Detailed Description

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

Fig. 1 to 4 schematically show a schematic view of a child's bed 1000 in an embodiment of the application. The child's bed 1000 is primarily intended to provide rest or play for children or infants. Specifically, the crib 1000 has a substantially rectangular frame structure, and includes a bed frame 10 (see fig. 5, 13 or 17) and a crib cover 1200 (e.g. a cloth cover, etc. see fig. 1 to 4) covering the outside of the bed frame 10, wherein the bed frame 10 is foldable, such that the crib 1000 is foldable and switchable between an unfolded state and a folded state. The child's bed 1000 has a small volume after folding, and is convenient for storage and transportation.

Fig. 5 shows a perspective view of a bed frame 10 according to a first embodiment of the present application. The frame 10 includes a first upright 111, a second upright 112, and an arm rest tube mechanism 120. Wherein the second upright 112 is disposed opposite to the first upright 111. The armrest tube mechanism 120 is movably coupled between the first upright 111 and the second upright 112, and the armrest tube mechanism 120 is switchable between an extended position (see fig. 5 and 6) and a collapsed position (see fig. 8). The armrest tube mechanism 120 is at least partially parallel to a horizontal plane when the armrest tube mechanism 120 is in the extended position.

In the above-mentioned bed frame 10, the armrest pipe mechanism 120 is movably connected between the first upright 111 and the second upright 112, so that the armrest pipe mechanism 120 has an unfolded position and a folded position, and when the armrest pipe mechanism 120 is in the folded position, the whole bed frame 10 is in a folded state, so that the volume of the bed frame 10 is reduced for storage and transportation. Because the armrest pipe mechanism 120 is at least partially parallel to the horizontal plane when in the extended position, the basket cover 1200 (e.g., cloth cover) mounted on the armrest pipe mechanism 120 tends to be flat when the armrest pipe mechanism 120 is in the extended position, so that the degree of fit between the basket cover 1200 and the armrest pipe mechanism 120 is better, and the appearance of the bed frame 10 covered with the basket cover 1200 is tidier.

In some embodiments, the first upright 111 and the second upright 112 are provided in plurality, the plurality of first uprights 111 and the plurality of second uprights 112 are alternately arranged along the circumferential direction, and the handrail tube mechanism 120 is provided between adjacent first uprights 111 and second uprights 112. Thus, when each armrest pipe mechanism 120 is in the extended position, each first upright 111, each armrest pipe mechanism 120, and each second upright 112 are sequentially connected and enclosed to form an annular structure. It should be understood that the term "plurality" as used herein means at least two.

Specifically, referring to fig. 5, the first upright 111 and the second upright 112 are provided with two, respectively, and the armrest pipe mechanism 120 is provided with four. When each arm rest tube mechanism 120 is in the extended position, each first upright 111 and each second upright 112 are connected by the arm rest tube mechanism 120 to form a rectangular bed frame 10. Referring to fig. 5-8, in some embodiments, the armrest tube mechanism 120 includes a first armrest tube set 121, the first armrest tube set 121 including a first armrest tube 122. The first armrest tube 122 has a first pivot end 1221A and a first slide end 1221B. The first pivot end 1221A is pivotally connected to the first upright 111 or the second upright 112, and the first sliding end 1221B is pivotally connected to the second upright 112 or the first upright 111. In other words, when the first pivot end 1221A is pivoted to one of the first upright 111 and the second upright 112, the first sliding end 1221B is pivoted to the other and slidingly connected thereto. When the armrest tube mechanism 120 is in the deployed position, the first and second uprights 111, 112 are spaced apart from one another (see fig. 5 and 6), and the corresponding first armrest tube 122 is at least partially parallel to a horizontal plane.

Referring to fig. 6 and 7, in some embodiments, the first handrail tube 122 includes a first tube segment 1222 and a second tube segment 1223 that are connected to each other and disposed at an angle. The first end of the first tube section 1222 away from the second tube section 1223 is a first pivot end 1221A, and the first end of the second tube section 1223 away from the first tube section 1222 is a first slide end 1221B. The first pivot end 1221A and the first sliding end 1221B are disposed at the ends of each tube segment, which is advantageous for improving the convenience of the connection between the first armrest tube 122 and the first upright 111 and the second upright 112, and simultaneously, when the armrest tube mechanism 120 is in the extended position, the first armrest tube 122 has the maximum extended length, so that the distance between the first upright 111 and the second upright 112 is maximized, and further, the bed frame 10 has a larger accommodation space in the extended state to support the child's bed cover 1200, thereby improving the area of the child's bed cover 1200 in the extended position, and providing a larger space for children to rest or entertain. More specifically, referring to fig. 6 and 7, when the armrest tube mechanism 120 is in the deployed position, the first tube segment 1222 is parallel to a horizontal plane, and the second tube segment 1223 extends downward from the second end of the first tube segment 1222.

In some embodiments, the angle α between the first tube segment 1222 and the second tube segment 1223 is greater than 90 °.

More specifically, in some embodiments, the angle α between the first tube segment 1222 and the second tube segment 1223 is 150 °. Of course, in some alternative embodiments, the angle α between the first tube segment 1222 and the second tube segment 1223 may also be 100 °, 120 °, 140 °, or the like, without limitation.

To improve the ease with which the first arm rest tube 122 is connected to the first upright 111 and the second upright 112, and to improve the ease with which the first arm rest tube 122 is switched between the extended position and the collapsed position, see fig. 6 and 8, the bedframe 10, in some embodiments, further includes a top corner 130. More specifically, in some embodiments, the first upright 111 or the second upright 112 is provided with a top corner 130, each top corner 130 has a first pivot portion Q1, and the first pivot portion Q1 is configured to pivot with the first pivot end 1221A.

Further, in some embodiments, the bedframe 10 also includes a slider 140. The first upright 111 or the second upright 112 is slidably provided with a slider 140. The sliding members 140 are each provided with a second pivot portion Q2, and the second pivot portion Q2 is configured to pivot with the first sliding end 1221B. When the top corner 130 connected to a certain first handrail tube 122 is provided to one of the first upright 111 and the second upright 112, the slider 140 connected to the first handrail tube 122 is provided to the other. When the user needs to switch the bed frame 10 from the unfolded state to the folded state, i.e. when the armrest pipe mechanism 120 is switched from the unfolded position to the folded position (when the state shown in fig. 6 is switched to the state shown in fig. 8), the user pushes or pulls the sliding member 140, so that the sliding member 140 drives the first sliding end 1221B of the first armrest pipe 122 to move downward (in the F1 direction) along the corresponding first upright 111 or second upright 112, and further the first sliding end 1221B of the first armrest pipe 122 can rotate at the second pivot portion Q2 of the sliding member 140, and simultaneously the first pivot end 1221A of the first armrest pipe 122 rotates at the first pivot portion Q1 of the top corner 130, so as to drive the first upright 111 and the second upright 112 to close to each other. When the user needs to switch the bed frame 10 from the folded state to the unfolded state, i.e. when the armrest pipe mechanism 120 is switched from the folded position to the unfolded position (when the state shown in fig. 8 is switched to the state shown in fig. 6), the sliding member 140 is pushed to drive the sliding member 140 to move the first sliding end 1221B of the first armrest pipe 122 upward (in the F2 direction) along the corresponding first upright 111 or second upright 112, so that the first sliding end 1221B of the first armrest pipe 122 can rotate at the second pivot portion Q2 of the sliding member 140, and simultaneously the first pivot end 1221A of the first armrest pipe 122 can rotate at the first pivot portion Q1 of the top corner 130, thereby driving the first upright 111 and the second upright 112 to be far away from each other.

More specifically, in some embodiments, as shown in fig. 5 and 6, in the annular bed frame 10 formed by connecting and enclosing the plurality of first upright posts 111, the plurality of second upright posts 112 and the plurality of first armrest tube groups 121, each of the top corners 130 disposed on the first upright posts 111 or the second upright posts 112 includes a first top corner 131 and a second top corner 132, and the first top corner 131 and the second top corner 132 are connected to each other and disposed at an included angle. The first top corner 131 and the second top corner 132 are each provided with a first pivot portion Q1, and the first pivot portion Q1 is configured to pivot with the first pivot end 1221A of the first handrail tube 122. Similarly, each sliding member 140 on the second upright 112 or the first upright 111 may also include a first sliding portion 141 and a second sliding portion 142, where the first sliding portion 141 and the second sliding portion 142 are connected to each other and disposed at an included angle. The first sliding portion 141 and the second sliding portion 142 are respectively provided with a second pivoting portion Q2, and the second pivoting portion Q2 is configured to pivot with the first sliding end 1221B of the first handrail tube 122. Thus, when the slider 140 slides on the second upright 112 or the first upright 111, the first sliding ends 1221B of the two first handrail tubes 122 connected to the same slider 140 slide up and down along with the slider 140 and pivot relative to the slider 140. At the same time, the first pivot ends 1221A of the two first handrail tubes 122 connected to the same top corner 130 pivot with respect to the top corner 130.

Referring to fig. 5 to 8, in the present embodiment, the first handrail tube group 121 includes two first handrail tubes 122. The first pivot end 1221A of one of the first handrail tubes 122 is pivotally connected to the first upright 111, and the first sliding end 1221B of one of the first handrail tubes 122 is pivotally connected to the second upright 112. The first pivot end 1221A of the other first armrest tube 122 is pivotally connected to the second upright 112, and the first sliding end 1221B of the other first armrest tube 122 is slidably pivotally connected to the first upright 111. In other words, when the first handrail tube group 121 includes two first handrail tubes 122, the first pivot end 1221A of one first handrail tube 122 is pivoted to the first upright 111, and the first sliding end 1221B of the first handrail tube 122 is pivoted to the second upright 112 and slidingly connected thereto, and the first pivot end 1221A of the other first handrail tube 122 is pivoted to the second upright 112, and the first sliding end 1221B of the first handrail tube 122 is slidingly pivoted to the first upright 111. More specifically, when the armrest tube mechanism 120 is in the deployed position, the two first armrest tubes 122 within the first armrest tube group 121 are juxtaposed in the horizontal direction, and the projections of the first tube sections 1222 of the two first armrest tubes 122 on a vertical plane parallel to the LR direction (left-right direction) and perpendicular to the horizontal plane at least partially overlap (see fig. 7).

The meaning of the above-mentioned "the two first handrail tubes 122 are juxtaposed in the horizontal direction, and the projections of the first tube sections 1222 of the two first handrail tubes 122 on the vertical plane parallel to the LR direction (left-right direction) and perpendicular to the horizontal plane at least partially overlap" will be described below with reference to fig. 5 and 7.

Fig. 5 schematically shows the bed frame 10 of this embodiment comprising two first uprights 111 and two second uprights 112 and a handrail tube mechanism 120. When the bed frame 10 is in the unfolded state, the bed frame 10 has a substantially square structure and is substantially symmetrical left and right and front and rear. Referring to fig. 5 and 7, taking one of the first upright 111 and the second upright 112 disposed in the left-right direction as an example, when the two first handrail tubes 122 disposed therebetween are in the deployed position, the first tube sections 1222 of the two first handrail tubes 122 are disposed side by side in the horizontal direction (specifically, can be regarded as being in the front-rear direction), and there is a partial overlap of the two first tube sections 1222 in the front-rear direction. Or, taking one of the first upright 111 and the second upright 112 disposed in the front-rear direction as an example, when the two first handrail tubes 122 disposed therebetween are in the deployed position, the first tube sections 1222 of the two first handrail tubes 122 are disposed in parallel in the horizontal direction (specifically, may be regarded as the left-right direction), and the two first tube sections 1222 are partially overlapped in the left-right direction.

It should be noted that unless explicitly specified and limited otherwise, in the various embodiments of the present application, terms of the orientations of the bedframe 10 such as "front", "back", "left", "right", etc. are based on the "front", "back", "left", "right" orientations shown in the bedframe 10 in the drawings, and the "front", "back" directions are schematically shown by arrows B, P, and the "left", "right" directions are schematically shown by arrows L, R. These directional terms are used only to make the description of the embodiments of the present application clearer and are not used to unduly limit the scope of the present application.

Referring to fig. 5 and 6, in some embodiments, a top corner 130 is provided on each of the first and second posts 111, 112. Each vertex 130 includes a first vertex 131 and a second vertex 132, the first vertex 131 and the second vertex 132 being interconnected and disposed at an included angle. The first top corner 131 and the second top corner 132 are each provided with a first pivot portion Q1, and the first pivot portion Q1 is configured to pivot with the first pivot end 1221A of the first handrail tube 122.

With continued reference to fig. 5 and 6, in some embodiments, a slider 140 is slidably disposed on both the first post 111 and the second post 112. The slider 140 can slide up and down on the first column 111 and the second column 112. Each sliding member 140 includes a first sliding portion 141 and a second sliding portion 142, where the first sliding portion 141 and the second sliding portion 142 are connected to each other and disposed at an included angle. The first sliding portion 141 and the second sliding portion 142 are respectively provided with a second pivoting portion Q2, and the second pivoting portion Q2 is configured to pivot with the first sliding end 1221B of the first handrail tube 122. When each first armrest pipe group 121 is switched from the unfolded position to the folded position, the sliding members 140 on each first upright 111 and each second upright 112 move downward (in the direction of F1) along the corresponding first upright 111 and second upright 112, and at the same time, the first sliding end 1221B of each first armrest pipe 122 pivots relative to the second pivoting portion Q2 of the sliding member 140, and the first pivoting end 1221A of each first armrest pipe 122 pivots relative to the first pivoting portion Q1 of the top corner 130, so that each first upright 111 and each second upright 112 can be close to each other, and the bed frame 10 can be switched from the unfolded state to the folded state. When each first armrest tube group 121 is switched from the folded position to the unfolded position, the sliding members 140 on each first upright 111 and each second upright 112 move upward (in the F2 direction) along the corresponding first upright 111 and second upright 112, and at the same time, the first sliding end 1221B of each first armrest tube 122 pivots relative to the second pivoting portion Q2 of the sliding member 140, and the first pivoting end 1221A of each first armrest tube 122 pivots relative to the first pivoting portion Q1 of the top corner 130, so that each first upright 111 and each second upright 112 are separated from each other, and the bed frame 10 is switched from the folded state to the unfolded state.

Referring to fig. 6 and 9, in some embodiments, the top corner 130 is provided with a locking mechanism 150. When the armrest tube mechanism 120 is in the extended position, the locking mechanism 150 can be in locking engagement with the slider 140 to limit the slider 140 from sliding relative to the upright 110 to maintain the bedframe 10 in the extended position.

With continued reference to fig. 6 and 9, in some embodiments, the locking mechanism 150 includes a locking member 151 pivotally connected to the top corner 130. Specifically, the top corner 130 has a supporting seat 133 thereon, and the locking member 151 is pivotally connected to the supporting seat 133. The lock 151 has an operation end 1511 and a lock end 1512, and the slider 140 is provided with a lock engagement portion 143. The locking member 151 is pivotable between a locking position and a unlocking position. The locking end 1512 can be in locking engagement with the locking engagement portion 143 when the locking member 151 is in the locked position. When the locking piece 151 is located at the unlocking position, the locking end 1512 can be disengaged from the locking engagement portion 143. More specifically, the pivot point of the locking member 151 and the supporting base 133 is located between the operating end 1511 and the locking end 1512, so that the locking member 151 is in a "see-saw" structure when pivoted on the supporting base 133, i.e. the operating end 1511 is pressed and rotated to bring the operating end 1511 close to the center of the first upright 111 or the second upright 112, so that the locking end 1512 is tilted away from the center of the first upright 111 or the second upright 112 when the locking member 151 is rotated. Of course, the locking piece 151 may be provided so that the operating end 1511 is pulled to disengage the locking end 1512 from the locking engagement portion 143.

Further, referring to fig. 9, in some embodiments, the locking mechanism 150 further includes a reset member 152. The operating end 1511 is operable to pivot the locking member 151 from the locking position to the unlocking position, and the reset member 152 is operable to bias the operating end 1511 to pivot the locking member 151 toward the locking position. The restoring member 152 is, for example, a spring, which abuts against the operation end 1511 and provides a restoring force to the operation end 1511 away from the center of the first upright 111 or the second upright 112. When the user needs to switch the locking member 151 from the locking position to the unlocking position, the user simply presses the operating end 1511, and the locking end 1512 is tilted away from the center of the first upright 111 or the second upright 112, so that the locking end 1512 can be disengaged from the locking engagement portion 143. Under the action of the reset element 152, the user only needs to release the operating end 1511, so that the locking element 151 can be switched from the unlocking position to the locking position.

Alternatively, in other embodiments, the supporting base 133 may be omitted, and the locking member 151 is directly pivoted to the top corner 130 (see fig. 32). Specifically, the top corner 130 is provided with a mounting seat 134, and a pressing channel 1341 is provided in the mounting seat 134. The operating end 1511 of the locking member 151 extends into the mounting block 134 and is received in the pressing channel 1341. More specifically, the pressing channel 1341 penetrates the mounting base 134 along the length direction thereof, and a button 153 is movably disposed in the pressing channel 1341, and the button 153 is located at a side of the operating end 1511 opposite to the upright post 110 and abuts against the operating end 1511. In this way, the user can push the operating end 1511 to rotate around the pivot point of the locking member 151 and the vertex angle 130 by directly pressing the button 153 horizontally, so that the locking end 1512 is tilted to disengage the locking engagement portion 143. Thus, the user can drive the locking piece 151 to rotate only by horizontally pressing the button 153 without pressing the rotating operation end 1511, so that the operation is more convenient and quick.

Of course, in some alternative embodiments, the implementation of the locking mechanism 150 is not limited to the above examples, so long as it can function as a locking slider 140.

Referring to fig. 5-9, in some embodiments, the first armrest stack 121 further includes a rotational coupling mechanism 123. The two first handrail tubes 122 are pivotally connected by a rotary connecting mechanism 123. Specifically, when the first handrail tube group 121 includes two first handrail tubes 122, the two first handrail tubes 122 are rotatably connected by the rotation connecting mechanism 123. When the sliding member 140 corresponding to one of the first handrail tubes 122 moves downward on the first upright 111 or the second upright 112, the first sliding end 122B of the first handrail tube 122 moves downward, so that the first handrail tube 122 inclines and has a downward moving tendency, at this time, the rotating connection mechanism 123 is driven by the first handrail tube 122 to also move downward, and under the action of the rotating connection mechanism 123, the other first handrail tube 122 can be driven to also have a downward moving tendency, so that the sliding member 140 corresponding to the other first handrail tube 122 can move downward relative to the second upright 112 or the first upright 111. It can be seen that the rotation connection mechanism 123 has a linkage function, and can enable the two first handrail tubes 122 between the adjacent first upright 111 and second upright 112 to rotate synchronously. By providing the rotational connection 123, a user may push or pull only a single slider 140 downward to collapse all of the armrest tube mechanism 120, thereby allowing the entire child bed 1000 to collapse.

Specifically, the rotational connection 123 is connected to the first tube sections 1222 of the two first armrest tubes 122, and the two first tube sections 1222 have overlapping areas when the two first armrest tubes 122 are in the deployed position. Further, when the armrest tube mechanism 120 is in the deployed position, i.e., the two first armrest tubes 122 are in the deployed position, the rotational connection 123 is located below each first tube segment 1222. Thus, the problem that the child bed cover 1200 does not fit to the ground due to the rotation connecting mechanism 123 protruding above the horizontal plane where the first armrest pipe 122 is located can be avoided.

It should be noted that "when the armrest pipe mechanism 120 is in the deployed position, the rotation connection mechanism 123 is located below each of the first pipe sections 1222" means that when the armrest pipe mechanism 120 is in the deployed position, the rotation connection mechanism 123 has an end portion with the first connection portion 12311 located at a lower level than an upper surface of the first pipe section 1222, as seen in a direction along which the first connection portion 12311 (see fig. 7) and the second connection portion 12312 (see fig. 7) are disposed on the rotation connection mechanism 123, in other words, the end portion of the rotation connection mechanism 123 with the first connection portion 12311 does not protrude from a horizontal plane where the upper surface of the first pipe section 1222 is located, so as to improve the degree of fit of the child bed covering 1200 covering the armrest pipe mechanism 120.

Referring to fig. 6-8, in some embodiments, the rotational coupling mechanism 123 includes a rotational member 1231. The rotation members 1231 are provided in two, and each rotation member 1231 is provided with a first connection portion 12311 and a second connection portion 12312. Each first armrest pipe 122 is correspondingly connected to the first connection part 12311 of each rotating member 1231, and the two second connection parts 12312 are rotatably connected. When the two first handrail tubes 122 of the first handrail tube group 121 are at the unfolded position, the two rotating members 1231 are overlapped with each other, and when the two first handrail tubes 122 of the first handrail tube group 121 are switched from the unfolded position to the folded position, the two rotating members 1231 are mutually rotated to form a certain included angle by the second connecting portion 12312. Specifically, as the first upright 111 and the second upright 112 approach each other, the angle between the two rotating members 1231 gradually increases.

Specifically, in some embodiments, as shown in fig. 10, the rotating member 1231 includes a first clamping plate 12313, a connecting plate 12314, and a second clamping plate 12315. The connecting plate 12314 is connected between the first clamping plate 12313 and the second clamping plate 12315, and the first clamping plate 12313, the connecting plate 12314 and the second clamping plate 12315 are enclosed to form a clamping groove 12316 (see fig. 10), so that the rotating member 1231 has a generally U-shaped structure. The first clamping plate 12313 and the second clamping plate 12315 are respectively provided with a first connecting portion 12311 and a second connecting portion 12312, and the first connecting portion 12311 is closer to the notch of the clamping groove 12316 than the second connecting portion 12312. The first armrest pipe 122 is limited in the clamping groove 12316 and connected to the two first connecting portions 12311. More specifically, the first and second connection portions 12311 and 12312 are both limiting holes. The first handrail tube 122 is placed in the catching groove 12316, and the first handrail tube 122 is connected to the first handrail tube 122 through a stopper hole (first connecting portion 12311) by a connecting member such as a screw or a bolt, so that the first handrail tube 122 can be stably mounted on the rotating member 1231. Further, the two rotating members 1231 may be rotatably connected through a limiting hole (second connecting portion 12312) by a rotating shaft or the like.

Referring to fig. 10, in some embodiments, the rotating member 1231 further includes a stiffener 12317. The first clamp plate 12313 and the second clamp plate 12315 are provided with reinforcing ribs 12317, and the reinforcing ribs 12317 on the first clamp plate 12313 extend toward the second clamp plate 12315, and the reinforcing ribs 12317 on the second clamp plate 12315 extend toward the first clamp plate 12313. The structural strength of the rotating member 1231 can be integrally improved by adding the reinforcing ribs 12317. In addition, the end of each stiffener 12317 adjacent to the notch of the clamping groove 12316 may be used to support the first armrest tube 122 (see fig. 7) that is confined within the clamping groove 12316.

Referring to fig. 11 and 12, in further alternative embodiments, the rotational coupling mechanism 123 includes two rotational coupling portions 1232, each rotational coupling portion 1232 including a clamping plate 12321 and a coupling post 12322 secured to the clamping plate 12321. The clamping plate 12321 is provided with a first connecting portion 12311, and the two first handrail tubes 122 are respectively connected with the first connecting portions 12311 of the two rotating connecting portions 1232 and pivotally connected by the connecting posts 12322 of the two rotating connecting portions 1232.

With continued reference to fig. 11 and 12, the clamping plates 12321 of the two rotating connection portions 1232 and the connection posts 12322 of the two rotating connection portions 1232 are surrounded to form the clamping groove 12316. The two first handrail tubes 122 are limited in the clamping groove 12316 and connected to the corresponding first connecting portions 12311. Or one of the two first handrail tubes 122 is positioned in the clamping groove 12316 to be connected with the corresponding first connecting portion 12311, and the other one is positioned outside the clamping groove 12316 and connected with the corresponding first connecting portion 12311. Or two first handrail tubes 122 are located outside the clamping groove 12316 and connected to the corresponding first connecting portions 12311.

Referring to fig. 13 and 14, in some embodiments, the bed frame 10 further includes a first guard assembly 160. Specifically, the first protection component 160 is disposed on the first handrail tube 122 and is located at a pivot point of the two first handrail tubes 122, that is, at a connection point of the first handrail tubes 122 and the rotation connection mechanism 123. When the armrest tube mechanism 120 is switched from the extended position to the collapsed position, the two first armrest tubes 122 are respectively pivoted relative to the rotational coupling mechanism 123 and enclose the rotational coupling mechanism 123 to form a first shear nip 127 (see fig. 8). The first guard assembly 160 is configured to shield the first shear trapping region 127 (see, for comparison, fig. 8 and 14). Thus, in the folding process of the bedstead 10 by the user, the child's bed cover 1200 can be prevented from entering the first shearing clamping area 127, so that the influence on the folding smoothness of the bedstead 10 is avoided, and meanwhile, the hand of the user can be prevented from entering the first shearing clamping area 127 by mistake, so that the possible clamping injury is prevented.

In one embodiment, at least one first handrail tube 122 is provided with a first shielding assembly 160, of the two first handrail tubes 122 between the first upright 111 and the second upright 112. In other words, any one of the first handrail tubes 122 may be provided with the first protection component 160, or both of the first handrail tubes 122 may be provided with the first protection component 160.

Referring to fig. 14 and 15, in some embodiments, the first guard assembly 160 includes a first guard shield 161 and a first guard connector 162 that are interconnected. The first protective barrier 161 is for shielding the first shear stuffed section 127. In this embodiment, the first protection baffle 161 has a substantially trapezoidal sheet structure, and the first protection connector 162 is disposed at a bottom edge of the first protection baffle 161. In this embodiment, the first protection baffle 161 and the first protection connector 162 are integrally formed, and in other embodiments, the first protection baffle 161 and the first protection connector 162 may be connected by riveting, welding, or the like. The side of the first guard connection 162 facing away from the first guard connection 162 forms a first arcuate concave surface 1621 that is capable of conforming to the outer wall of the first armrest tube 122. In this embodiment, two first connecting protrusions are disposed at intervals on one side of the first arc-shaped concave surface 1621, and each first connecting protrusion is provided with a first connecting hole 1622. In other embodiments, the number of the first connecting protrusions and the first connecting holes 1622 may be more or less than two. Two first fixing holes (not shown in the drawings) opposite to the two first connecting holes 1622 are provided on the corresponding first handrail tube 122, and two fasteners (e.g., blind bolts, screws or rivets, etc.) pass through the corresponding first connecting holes 1622 and the first fixing holes, respectively, to connect the first protection assembly 160 and the first handrail tube 122. In this manner, stability of the first shielding assembly 160 after installation may be improved. Of course, in other alternative embodiments, the first protection component 160 may be further connected to the first handrail tube 122 by a clamping manner, or the first protection component 160 may be further integrally formed on the first handrail tube 122.

Fig. 16 shows a perspective view of a bedframe 10 according to a second embodiment of the application, the bedframe 10 being similar to the first embodiment described above, including a first upright 111, a second upright 112, and a handrail tube mechanism 120. Wherein the second upright 112 is disposed opposite to the first upright 111. The armrest tube mechanism 120 is movably coupled between the first upright 111 and the second upright 112, and the armrest tube mechanism 120 is switchable between an extended position (see fig. 16 and 17) and a collapsed position (see fig. 19). The armrest tube mechanism 120 is at least partially parallel to a horizontal plane when the armrest tube mechanism 120 is in the extended position.

As can be seen by comparing the frame 10 of the first embodiment with the frame 10 of the second embodiment (see fig. 5 and 16), the arm rest tube mechanism 120 of the frame 10 of the second embodiment is different from the arm rest tube mechanism 120 of the frame 10 of the first embodiment.

Referring to fig. 16, in some embodiments, the armrest tube mechanism 120 includes a second armrest tube set 124, the second armrest tube set 124 includes both a second armrest tube 125 and a third armrest tube 126, and both the second armrest tube 125 and the third armrest tube 126 are provided. Referring to fig. 17, each of the second handrail tubes 125 has a second pivot end 1251A and a second sliding end 1251B, the two second pivot ends 1251A are pivoted, and the two second sliding ends 1251B are slidably disposed on the first upright 111 and the second upright 112, and are pivoted to the first upright 111 and the second upright 112, respectively. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B, the two third pivot ends 1261A are pivoted, and the two fourth pivot ends 1261B are pivoted to the first upright 111 and the second upright 112 respectively. When the armrest pipe mechanism 120 is in the extended position, at least a portion of each second armrest pipe 125 and at least a portion of each third armrest pipe 126 are parallel to a horizontal plane. Therefore, when the armrest tube mechanism 120 is in the unfolded position, the basket cover 1200 (e.g. cloth cover) mounted on the armrest tube mechanism 120 is flat, so that the basket cover 1200 is better attached to the armrest tube mechanism 120, and the appearance of the bed frame 10 coated with the basket cover 1200 is tidy.

Referring to fig. 18, in some embodiments, the second handrail tube 125 includes a third tube segment 1252 and a fourth tube segment 1253 that are connected and disposed at an angle, a first end of the third tube segment 1252 away from the fourth tube segment 1253 is a second pivot end 1251A, and a first end of the fourth tube segment 1253 away from the third tube segment 1252 is a second slide end 1251B. Meanwhile, the third handrail tube 126 includes a fifth tube segment 1262 and a sixth tube segment 1263 that are connected and disposed at an included angle, a first end of the fifth tube segment 1262 away from the sixth tube segment 1263 is a fourth pivot end 1261B, and a first end of the sixth tube segment 1263 away from the fifth tube segment 1262 is a third pivot end 1261A. When the armrest tube mechanism 120 is in the extended position, each third tube segment 1252 and each fifth tube segment 1262 are in a horizontal plane, and the fourth tube segment 1253 extends downward from the second end of the third tube segment 1252 and the sixth tube segment 1263 extends downward from the second end of the fifth tube segment 1262. And the second handrail tube 125 and the third handrail tube 126 connected to the first upright 111 or the second upright 112 are juxtaposed in the horizontal direction and the projected portions of the fifth tube section 1262 and the third tube section 1252 on the vertical plane parallel to the front-rear direction (BP direction) and perpendicular to the horizontal plane coincide.

The meaning of "the second handrail tube 125 and the third handrail tube 126 are juxtaposed in the horizontal direction and the projected portion of the fifth pipe section 1262 and the third pipe section 1252 on the vertical plane parallel to the front-rear direction and perpendicular to the horizontal plane overlap" mentioned above is explained below with reference to fig. 16 and 18.

Fig. 16 schematically illustrates the frame 10 of this embodiment comprising two first uprights 111 and two second uprights 112 and a handrail tube mechanism 120. When the bed frame 10 is in the unfolded state, the bed frame 10 has a substantially square structure and is substantially symmetrical left and right and front and rear. In this embodiment, one of the first upright 111 and the second upright 112 disposed in the front-rear direction is taken as an example, when two second handrail tubes 125 and two third handrail tubes 126 disposed therebetween are in the deployed position, the second handrail tubes 125 and the third handrail tubes 126 are disposed in parallel in the horizontal direction (specifically, can be regarded as being in the left-right direction), and the third tube section 1252 of the second handrail tubes 125 and the fifth tube section 1262 of the third handrail tubes 126 are partially overlapped in the left-right direction (see fig. 16 and 18).

Referring to fig. 16 and 18, in some embodiments, the second pivotally connected ends 1251A of the two third tube segments 1252 are juxtaposed in a horizontal direction and have a partial overlap in projection on a vertical plane parallel to the front-to-back direction and perpendicular to the horizontal plane. Specifically, taking one of the first upright 111 and the second upright 112 disposed along the front-rear direction as an example, when the two second handrail tubes 125 disposed therebetween are in the unfolded position, the second pivot ends 1251A corresponding to the two third tube segments 1252 are disposed in parallel in the horizontal direction (specifically, can be considered as being in the left-right direction), and the second pivot ends 1251A corresponding to the two third tube segments 1252 are partially overlapped in the left-right direction.

In some embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 is greater than 90 °.

More specifically, in some embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 is 150 °. Of course, in some alternative embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 may also be 100 °, 120 °, 140 °, etc., without limitation.

In some embodiments, the angle α (not shown) between the fifth tube segment 1262 and the sixth tube segment 1263 is greater than 90 °.

More specifically, in some embodiments, the angle α between the fifth tube segment 1262 and the sixth tube segment 1263 is 150 °. Of course, in some alternative embodiments, the included angle α between the fifth pipe segment 1262 and the sixth pipe segment 1263 may be 100 °, 120 °, 140 °, or the like, which is not particularly limited herein.

Referring to fig. 16 and 18, the second armrest tube group 124 also includes, for example, the rotational coupling mechanism 123 described in the first embodiment. Specifically, the rotation connection mechanism 123 is connected to the second handrail tube 125 and the third handrail tube 126. In this embodiment, two rotation connection mechanisms 123 are provided in one second handrail tube group 124, and the second handrail tube 125 and the third handrail tube 126 which are disposed opposite to each other are connected by one rotation connection mechanism 123 along the parallel direction of the second handrail tube 125 and the third handrail tube 126.

Referring to fig. 16, in some embodiments, the bedframe 10 also includes, for example, the top corners 130 and the sliders 140 described in the first embodiment, and the top corners 130 have a locking mechanism 150. Referring to what is described in the first embodiment, each of the first and second columns 111 and 112 is provided with a top corner 130 and a slider 140.

Specifically, the vertex angle 130 includes a first vertex angle portion 131 and a second vertex angle portion 132, the first vertex angle portion 131 and the second vertex angle portion 132 are connected to each other and are disposed at an included angle, the first vertex angle portion 131 and the second vertex angle portion 132 are both provided with a first pivot portion Q1, and the first pivot portion Q1 is pivoted with a fourth pivot end 1261B. Specifically, the sliding member 140 includes a first sliding portion 141 and a second sliding portion 142, where the first sliding portion 141 and the second sliding portion 142 are connected to each other and disposed at an included angle, and the first sliding portion 141 and the second sliding portion 142 are both provided with a second pivot portion Q2, and the second pivot portion Q2 is pivoted to the second sliding end 1251B.

When the bed frame 10 of the present embodiment is used, the operation of the armrest pipe mechanism 120 disposed between the first upright 111 and the second upright 112 can be described when the user needs to switch the bed frame 10 from the expanded state to the collapsed state, that is, when the armrest pipe mechanism 120 is switched from the expanded position to the collapsed position (when the state shown in fig. 17 is switched to the state shown in fig. 19).

Referring to fig. 17-19, a user pushes or pulls the slider 140 such that the slider 140 moves the second sliding end 1251B of the corresponding second handrail tube 125 downward (in the F1 direction) on the corresponding first and second upright 111, 112. Since each third tube segment 1252 is horizontally disposed in the expanded state, the fourth tube segment 1253 extends downward from the second end of the third tube segment 1252, the fifth tube segment 1262 is horizontally disposed, and the sixth tube segment 1263 extends downward from the second end of the fifth tube segment 1262, when the second sliding end 1251B moves downward with the sliding member 140, the second handrail tube 125 pivots, and the two second pivoting ends 1251A pivot with respect to each other such that the two second handrail tubes 125 approach each other. Meanwhile, the rotation connection mechanism 123 moves downwards along with the second handrail tube 125, under the linkage action of the rotation connection mechanism 123, the third handrail tube 126 has a downward rotation trend relative to the correspondingly arranged top angle 130, and the two third pivot ends 1261A rotate relative to each other, so that the two third handrail tubes 126 are close to each other, and finally the first upright post 111 and the second upright post 112 are close to each other. By providing the rotational connection 123, a user may push or pull only a single slider 140 downward to collapse all of the armrest tube mechanism 120, thereby allowing the entire child bed 1000 to collapse.

When the bed frame 10 of the present embodiment is used, the operation of the armrest pipe mechanism 120 disposed between the first upright 111 and the second upright 112 can be similarly described when the user needs to switch the bed frame 10 from the collapsed state to the expanded state, that is, when the armrest pipe mechanism 120 is switched from the collapsed position to the expanded position (when the state shown in fig. 19 is switched to the state shown in fig. 17).

Referring to fig. 19, the user pushes the sliding member 140, so that the sliding member 140 drives the second sliding end 1251B of the second handrail tube 125 to move upward along the corresponding first upright 111 and second upright 112, and at this time, the two second handrail tubes 125 move away from each other to push the first upright 111 and second upright 112 away from each other. In this process, the fourth pivot ends 1261B of the two third handrail tubes 126 rotate upward relative to the first pivot portion Q1, and the two third handrail tubes 126 are further away from each other to push the first upright 111 and the second upright 112 away from each other. When the two second handrail tubes 125 and the two third handrail tubes 126 are fully deployed, the sliding member 140 can be locked to the first upright 111 and the second upright 112 by the locking mechanism 150.

Referring to fig. 20-22, the second embodiment provides a bed frame 10 that can further include a second guard assembly 170. Wherein fig. 20 shows a portion of the structure of the frame 10 when the second arm rest tube set 124 is in the expanded position, fig. 21 shows the frame 10 of fig. 20 with the second arm rest tube set 124 in a transition position between the expanded position and the collapsed position, and fig. 22 shows the frame 10 of fig. 20 with the second arm rest tube set 124 in the collapsed position. In this embodiment, a second guard assembly 170 is disposed on each of the second handle tubes 125 and/or the third handle tubes 126. In other words, the second guard assembly 170 may be disposed only on each second handrail tube 125, or only on each third handrail tube 126, or both the second handrail tube 125 and the third handrail tube 126. Further, the second protection component 170 is located at a pivot joint with the second handrail tube 125 and the third handrail tube 126 connected to the first upright 111 or the second upright 112, i.e. at a joint between the second handrail tube 125 and the rotation connection mechanism 123, and/or at a joint between the third handrail tube 126 and the rotation connection mechanism 123. When the handrail tube mechanism 120 is switched from the deployed position to the retracted position, the second handrail tube 125 and the third handrail tube 126, which are connected to the first upright 111 or the second upright 112, respectively, pivot relative to the corresponding rotation connection mechanism 123, and enclose the corresponding rotation connection mechanism 123 to form a second shearing clamping area 128 (see fig. 19), and the second protection assembly 170 is configured to shield the second shearing clamping area 128 (see fig. 19 and 22, respectively). Thus, in the folding process of the bedstead 10, the child's bed cover 1200 can be prevented from entering the second shearing clamping area 128, so that the influence on the folding smoothness of the bedstead 10 is avoided, and meanwhile, the hand of the user can be prevented from mistakenly entering the second shearing clamping area 128, so that the possible clamping injury is prevented.

As shown in fig. 19, when the armrest tube mechanism 120 is switched from the extended position to the collapsed position, the two sixth tube segments 1263 pivot relative to one another and gradually enclose to form the third shear grip region 129. Specifically, here, the region formed by the inner periphery of the two sixth pipe segments 1263 is referred to. Specifically, as shown in fig. 20 to 22, in the present embodiment, the second guard assembly 170 is disposed on each of the third handrail tubes 126, and when the second guard assembly 170 is disposed on each of the third handrail tubes 126, the second guard plate 170 extends from the fifth tube segment 1262 toward the sixth tube segment 1263, so that the second guard assembly 170 also serves to shield the third shearing pinch-in region 129 (see fig. 19 and 22). In this way, not only can the child's cover 1200 be similarly prevented from entering the third pinch-out region 129, but also a hand can be prevented from misentering the third pinch-out region 129.

Specifically, as shown in fig. 23, the second guard assembly 170 of the bed frame 10 in the second embodiment includes a second guard shield 171 and a second guard connector 172 connected to each other. The second protective baffle 171 is used for shielding the second shearing and filling region 128 and the third shearing and filling region 129. In this embodiment, the second protection baffle 171 has a substantially trapezoidal sheet structure, and the second protection connector 172 is disposed at the bottom edge and the side edge of one side of the second protection baffle 171. In this embodiment, the second protection baffle 171 and the second protection connector 172 are integrally formed, and in other embodiments, the second protection baffle 171 and the second protection connector 172 may be connected by riveting, welding, or the like. The side of the second guard connection 172 facing away from the second guard baffle 171 forms a second arcuate concave surface 1721 that is capable of conforming to the outer wall of the second handrail tube 125 and/or the third handrail tube 126. In this embodiment, two second connecting protrusions are disposed at a side of the second arc concave surface 1721 at intervals, and each second connecting protrusion is provided with a second connecting hole 1722. In other embodiments, the number of the second connecting protrusions and the second connecting holes 1722 may be more or less than two. Two second fixing holes (not shown in the drawing) opposite to the two second connecting holes 1722 are provided on the corresponding second handrail tube 125 and/or the third handrail tube 126, and two fasteners (such as a blind rivet, a screw or a rivet) pass through the corresponding second connecting holes 1722 and the second fixing holes to connect the second protection assembly 170 with the second handrail tube 125 and/or the third handrail tube 126. In this way, stability of the second shield assembly 170 after installation may be improved. Of course, the second protection plate 170 may also be mounted on the second handrail tube 125 and/or the third handrail tube 126 by other manners, such as a clamping connection, etc., without being limited thereto.

As shown in fig. 17 and 18, when the armrest tube mechanism 120 is switched between the deployed position and the stowed position, the two sixth tube segments 1263 pivot relative to one another and gradually enclose to form the third shear pinch region 129. Specifically, here, the outer sides of the two sixth pipe segments 1263 enclose a formed area. Alternatively, in other alternative embodiments, the second shield plate 171 of the second shield assembly 170 may have other shapes. For example, the second shield 171 may have a substantially rectangular sheet-like structure. As shown in fig. 27 and 28, in an embodiment, the second protective barrier 171 includes a first plate 1711 and a second plate 1712 connected together. The first plate 1711 is a right trapezoid sheet structure, the second plate 1712 is a triangle sheet structure, and the second plate 1712 is disposed at the oblique side edge of the first plate 1711, so that the whole second protective baffle 171 is rectangular. Thus, as shown in fig. 24 to 26, when the second protective baffle 171 is mounted on each of the third handrail tubes 126, the first plate body 1711 can be used to block both the second shearing clamping area 128 and the third shearing clamping area 129, and the third shearing clamping area 129 is always blocked, that is, it is equivalent to that either the third shearing clamping area 129 on the inner side of the sixth tube segment 1263 or the third shearing clamping area 129 on the outer side of the sixth tube segment 1263 is blocked (see fig. 18, 19, 22 and 26). Specifically, as shown in fig. 27 and 28, an arc-shaped groove 1713 is formed at the junction of the first plate 1711 and the second plate 1712. The arc-shaped groove 1713 is adapted to the sixth pipe segment 1263, and plays a role in avoiding, so that after the second protective baffle 171 is installed on the third handrail pipe 126, the first plate 1711 and the second plate 1712 can be in the same vertical plane, so as to respectively cover the third shearing clamping area 129 inside the sixth pipe segment 1263 and the third shearing clamping area 129 outside the sixth pipe segment 1263. Specifically, a second connecting hole 1722 is formed on the groove wall of the arc-shaped groove 1713 and the first plate 1711, and two fasteners (such as a blind rivet, a screw or a rivet) respectively pass through the corresponding second connecting hole 1722 to connect the sixth pipe segment 1263 and the rotating connecting mechanism 123 (such as the rotating member 1231 or the clamping plate 12321) so as to connect the second protection assembly 170 with the third handrail tube 126.

The "inner side" of the sixth pipe section 1263 refers to a side of the sixth pipe section 1263 facing an angle smaller than 180 degrees with respect to the fifth pipe section 1262, and the "outer side" of the sixth pipe section 1263 refers to a side of the sixth pipe section 1263 facing away from an angle smaller than 180 degrees with respect to the fifth pipe section 1262. In other words, the "inner side" of the sixth pipe segment 1263 refers to the lower side of the sixth pipe segment 1263 in the deployed state of the handrail tube mechanism as shown in fig. 24, and the "outer side" of the sixth pipe segment 1263 refers to the upper side of the sixth pipe segment 1263 in the deployed state of the handrail tube mechanism as shown in fig. 24. Alternatively, in some alternative embodiments, the armrest tube mechanism 120 includes a second armrest tube set 124, and the second armrest tube set 124 may include only two second armrest tubes 125 as described above. Each second handrail tube 125 has a second pivot end 1251A and a second sliding end 1251B, the two second pivot ends 1251A are pivoted, and the two second sliding ends 1251B are slidably disposed on the first upright 111 and the second upright 112, and are pivoted to the first upright 111 and the second upright 112, respectively. Each second armrest tube 125 has at least a portion of its tube section parallel to the horizontal plane when the armrest tube mechanism 120 is in the extended position.

Alternatively, in other alternative embodiments, the armrest tube mechanism 120 includes a second armrest tube set 124, and the second armrest tube set 124 may include only two of the third armrest tubes 126 described above. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B, the two third pivot ends 1261A are pivoted, and the two fourth pivot ends 1261B are pivoted to the first upright 111 and the second upright 112 respectively. Each third handrail tube 126 has at least a portion of its tube segments parallel to the horizontal when the handrail tube mechanism 120 is in the deployed position.

Fig. 29 shows a perspective view of a bed frame 10 according to a third embodiment of the present application, which bed frame 10 is similar to the first or second embodiment described above. The bed frame 10 includes a plurality of columns 110 (which may be considered as first column 111 and second column 112 in the first embodiment or the second embodiment) and a plurality of arm rest tube mechanisms 120. More specifically, the plurality of columns 110 are arranged at intervals along the circumferential direction, and the handrail tube mechanism 120 is movably connected between two adjacent columns 110. The armrest tube mechanism 120 is switchable between an extended position and a collapsed position to enable the bedframe 10 to be switched between an extended state and a collapsed state. The armrest tube mechanism 120 is at least partially parallel to a horizontal plane when the armrest tube mechanism 120 is in the extended position. Wherein the plurality of columns 110 are spaced apart from one another when the frame 10 is in the expanded state (see fig. 17), and the plurality of columns 110 are collapsed from one another when the frame 10 is in the collapsed state.

In some examples of the third embodiment, the armrest tube mechanism 120 includes at least one of a first armrest tube set 121 and a second armrest tube set 124.

Specifically, the bed frame 10 in the third embodiment shown in fig. 29 includes both the first arm rest tube set 121 and the second arm rest tube set 124. Specifically, reference may be made to the first arm rest tube set 121 in the bed frame 10 provided in the first embodiment, and reference may be made to the second arm rest tube set 124 in the bed frame 10 provided in the second embodiment, with respect to the second arm rest tube set 124.

In some embodiments, as shown in fig. 29, the bedframe 10 includes four columns 110 that are circumferentially spaced apart. For clarity of understanding of the handrail tube mechanism 120 disposed between the columns 110, the four columns 110 may be referred to as a first column 111, a second column 112, a third column 113, and a fourth column 114 in that order. The first armrest pipe group 121 is disposed between the first upright 111 and the second upright 112, and between the third upright 113 and the fourth upright 114, and the two first armrest pipe groups 121 are disposed opposite to each other. A second armrest pipe group 124 is arranged between the first upright 111 and the fourth upright 114 and between the second upright 112 and the third upright 113, and the two second armrest pipe groups 124 are arranged oppositely. When in the expanded state, the bed frame 10 has a generally rectangular configuration.

Referring to fig. 29, in some embodiments, the first upright 111, the second upright 112, the third upright 113, and the fourth upright 114 are each provided with a top corner 130 and a slider 140. The top corner 130 includes a first top corner 131 and a second top corner 132, the first top corner 131 and the second top corner 132 are connected to each other and are disposed at an included angle, and the first top corner 131 and the second top corner 132 are both provided with a first pivot portion Q1. Specifically, one first pivot portion Q1 is pivoted to the first pivot end 1221A of the first handrail tube 122, and the other first pivot portion Q1 is pivoted to the fourth pivot end 1261B of the third handrail tube 126.

With continued reference to fig. 29, in some embodiments, the slider 140 includes a first slider portion 141 and a second slider portion 142, the first slider portion 141 and the second slider portion 142 being connected to each other and disposed at an angle. The first sliding portion 141 and the second sliding portion 142 are each provided with a second pivoting portion Q2. Specifically, one second pivot portion Q2 is pivoted to the first sliding end 1221B of the first handrail tube 122, and the other second pivot portion Q2 is pivoted to the second sliding end 1251B of the second handrail tube 125.

Referring to fig. 30, further, in a third embodiment, the bedframe 10 includes both a first guard assembly 160 and a second guard assembly 170. Specifically, the structure and the arrangement position of the first guard assembly 160 can refer to the first guard assembly 160 in the bed frame 10 provided in the first embodiment, and the structure and the arrangement position of the second guard assembly 170 can refer to the second guard assembly 170 in the bed frame 10 provided in the second embodiment, which are not described herein.

It should be noted that, in the third embodiment, the second shielding plate 171 in the second shielding assembly 170 may have a trapezoidal sheet structure (see fig. 23 and 30), and may have a rectangular sheet structure (see fig. 27 and 31).

Referring to fig. 33 and 34, the fourth embodiment of the present application also provides a frame 10, and the frame 10 is a variation of the frame 10 shown in the first embodiment and includes a plurality of upright posts 110 and a plurality of arm rest tube mechanisms 120. Wherein, a plurality of stand columns 110 are arranged at intervals along the circumferential direction, and a handrail mechanism 120 is movably connected between every two adjacent stand columns 110. The arm rest tube mechanism 120 includes at least one pair of arm rest tubes including two arm rest tubes that are interdigitated and pivotally connected, each arm rest tube mechanism 120 being switchable between an expanded position and a collapsed position to enable the bed frame 10 to be switchable between an expanded state and a collapsed state.

It should be noted that, the "pair of handrail tubes" in the fourth embodiment may refer to two first handrail tubes 122, but it should be emphasized that the two first handrail tubes 122 are straight tubes, that is, the first tube segments 1222 and the second tube segments 1223 are aligned. In addition, the fourth embodiment of the bed frame 10 omits the rotation connection mechanism 123 in comparison with the first embodiment of the bed frame 10, that is, when two first arm rest pipes 122 are provided between the two upright posts 110, the two first arm rest pipes 122 are directly pivoted instead of being pivoted through the rotation connection mechanism 123.

Further, referring to Figs. 35 and 36, the fourth embodiment of the bedframe 10 also includes a plurality of third guard assemblies 180. Specifically, each pair of handrail pipes is provided with a third protection component 180, and the third protection component 180 is mounted on at least one handrail pipe and is located at the pivot joint of the two handrail pipes. Each third guard assembly 180 is configured to shield a fourth sheared-filling area α1 (see fig. 34) formed between two handrail tubes (i.e., the two first handrail tubes 122) of a corresponding pair of handrail tubes when each handrail tube mechanism 120 is switched between the deployed position and the collapsed position. In this way, the child's bed cover 1200 or hand can also be prevented from being accidentally inserted into the fourth cut-and-fill area α1 when folding this type of bed frame 10.

In particular, referring to fig. 35 and 36, the third shield assembly 180 includes a third shield-and-shield plate 181 and a third shield connector (not shown in the drawings) that are connected to each other. The third shielding plate 181 is used for shielding the fourth shearing stuffed section α1. In this embodiment, the third shielding plate 181 has a substantially rectangular plate structure, and the third shielding connector is disposed at an edge of one side of the third shielding plate 181. In this embodiment, the third shielding plate 181 and the third shielding connector are integrally formed, and in other embodiments, the third shielding plate 181 and the third shielding connector may be connected by riveting, welding, or the like. A third arc-shaped concave surface (not shown in the drawing) which can be attached to the outer wall of the handrail tube is formed on one side of the third protection connecting member facing away from the third protection barrier 181. In this embodiment, two third connecting protrusions (not shown in the drawings) are disposed at intervals on one side of the third arc-shaped concave surface, and each third connecting protrusion is provided with a third connecting hole (not shown in the drawings). In other embodiments, the number of the third connecting protrusions and the third connecting holes may be more than two or less than two. Two third fixing holes (not shown in the drawing) opposite to the two third connecting holes are formed in the corresponding handrail tube, and two fasteners (such as blind rivets, screws or rivets) respectively penetrate through the corresponding third connecting holes and the corresponding third fixing holes to connect the third protection assembly 180 with the handrail tube. In this manner, stability of the third shielding assembly 180 after installation may be improved. Of course, in other alternative embodiments, the third protection assembly 180 may be connected to the handrail tube by a snap connection, or the third protection assembly 180 may be integrally formed on the handrail tube.

Referring to fig. 37 and 38, a fifth embodiment of the present application also provides a frame 10, which is a variation of the frame 10 shown in the second embodiment described above, and which includes a plurality of upright posts 110 and a plurality of arm rest tube mechanisms 120. Wherein, a plurality of stand columns 110 are arranged at intervals along the circumferential direction, and a handrail mechanism 120 is movably connected between every two adjacent stand columns 110. The handrail tube mechanism 120 includes two pairs of handrail tubes, which are pivotally connected to each other. Specifically, each pair of handrail tubes comprises two handrail tubes, and the two handrail tubes are mutually intersected and pivoted. Each arm rest tube mechanism 120 is switchable between an extended position and a collapsed position to switch the bedframe 10 between an extended state and a collapsed state.

It should be noted that, in the fifth embodiment, the "pair of handrail pipes" may refer to the second handrail pipe 125 and the third handrail pipe 126, but it should be emphasized that the second handrail pipe 125 and the third handrail pipe 126 are straight pipes, that is, the third pipe section 1252 and the fourth pipe section 1253 are aligned, and the fifth pipe section 1262 and the sixth pipe section 1263 are aligned. In addition, the frame 10 of the fifth embodiment omits the rotation connection mechanism 123, compared with the frame 10 of the second embodiment, that is, the direct pivoting between the second arm rest pipe 125 and the third arm rest pipe 126 is equivalent to the pivoting through the rotation connection mechanism 123.

Further, referring to Figs. 39 and 40, the bed frame 10 of the fifth embodiment further includes a plurality of third guard assemblies 180. Specifically, each pair of handrail tubes is provided with a third protection assembly 180, and the third protection assembly 180 is mounted on at least one handrail tube and located at the pivot point of the two handrail tubes, i.e. the third protection assembly 180 may be mounted on the second handrail tube 125 and/or the third handrail tube 126. Thus, each third guard assembly 180 may be used to shield a fourth sheared-filled region α1 (see fig. 34) formed between the second handrail tube 125 and the third handrail tube 126 as each handrail tube mechanism 120 is switched between the deployed position and the collapsed position. In this way, the child's bed cover 1200 or hand can also be prevented from being accidentally inserted into the fourth cut-and-fill area α1 when folding this type of bed frame 10.

The present application also provides a bed frame 10 (not shown), the bed frame 10 including both a plurality of columns 110 and a plurality of arm tube mechanisms 120. Wherein, a plurality of stand columns 110 are arranged at intervals along the circumferential direction, and a handrail mechanism 120 is movably connected between every two adjacent stand columns 110. Specifically, the armrest pipe mechanism 120 includes the armrest pipe mechanism 120 of the fourth embodiment described above and also includes the armrest pipe mechanism 120 of the fifth embodiment described above for the entire bed frame 10. In other words, the bed frame 10 can be also considered similar to the bed frame 10 of the third embodiment, except that each of the first arm rest tubes 122 in the first arm rest tube set 121 is a straight tube, each of the second arm rest tubes 125 and the third arm rest tubes 126 in the second arm rest tube set 124 is a straight tube, and the rotation connection mechanism 123 is omitted. Two first handrail pipes 122 of the first handrail pipe group 121 are directly pivoted, and a second handrail pipe 125 of the second handrail pipe group 124 is directly pivoted with a third handrail pipe 126. Further, since the third guard assembly 180 is also provided to each of the armrest pipe mechanisms 120 of the bedframe 10, the bedframe 10 can still be prevented from being pinched by the child's bed cover 1200 or hands during folding by the third guard assembly 180. In summary, depending on the type of the bed frame 10, different types of guard assemblies (e.g., the first guard assembly 160, the second guard assembly 170, the third guard assembly 180, etc.) may be selectively disposed on the arm rest tube of the bed frame 10. Each guard assembly is configured to block a sheared filled region (e.g., a first sheared filled region 127, a second sheared filled region 128, a third sheared filled region 129, a fourth sheared filled region α1, etc.) formed between two handrail tubes of a corresponding pair of handrail tubes when each handrail tube mechanism 120 is switched between an extended position and a retracted position. Thus, the child bed cover or the hand can be prevented from being stuffed.

The bed frame 10 and the child's bed 1000 according to one aspect of the present application have at least the following technical effects:

In the bed frame 10 and the child's bed 1000 of the present application, the armrest pipe mechanism 120 is movably connected between the first upright 111 and the second upright 112, so that the armrest pipe mechanism 120 has an extended position and a retracted position, and when the armrest pipe mechanism 120 is in the retracted position, the whole bed frame 10 can be in a retracted state, so that the volume of the bed frame 10 is reduced for storage and transportation. When the armrest pipe mechanism 120 is in the unfolded position, at least part of the armrest pipe mechanism 120 is parallel to the horizontal plane, so that the child bed coating (such as a cloth cover) mounted on the armrest pipe mechanism 120 tends to be flat when the armrest pipe mechanism 120 is in the unfolded position, so that the child bed coating is better in fit with the armrest pipe mechanism 120, and further, the appearance of the bedstead 10 coated with the child bed coating is tidy. In other words, the upper surface of the armrest pipe member is flattened when the bedframe according to the present application and the cot 1000 including the same are in the unfolded state, so that the covering of the cot laid on the bedframe is more conformable and flattened.

In another aspect, the bed frame 10 and the cot 1000 according to the present application have at least the following technical effects:

In the bedframe 10 and the child's bed 1000 of the present application, no matter how the bedframe 10 is configured (for example, the upper ends of the armrest pipe mechanisms 120 are flush, or the first armrest pipe 122, the second armrest pipe 125 and the third armrest pipe 126 may be straight pipes, etc.), the cut-and-fill area may be blocked by providing the protection component (for example, the first protection component 160 is provided to block the first cut-and-fill area 127, the second protection component 170 is provided to block the second cut-and-fill area 128 and the third cut-and-fill area 129, or the protection component 180 is provided to block the fourth cut-and-fill area α1), so that during the folding process of the bedframe 10 by a user, the child's bed cover 1200 is prevented from entering the cut-and-fill area, thereby avoiding the influence on the folding smoothness of the bedframe 10, and avoiding the hand of the user from entering the cut-and-up situation that may occur.

Referring back to fig. 1-4, the child's bed cover 1200 of the child's bed 1000 may include a generally rectangular bottom support sheet 1210 and four side support sheets 1220 connected to four sides of the bottom support sheet 1210, respectively. Wherein the shape of the bottom support sheet 1210 is adapted to the horizontal cross-sectional shape of the bedframe 10 in the unfolded state. For example, in this embodiment, the bed frame 10 has a rectangular horizontal cross-sectional shape and the bottom support sheet 1210 in the expanded state. More specifically, each side support piece 1220 is connected between the corresponding first upright 111 and second upright 112, i.e., a side support piece 1220 is connected between each first upright 111 and each second upright 112. The bottom support sheet 1210 is connected to two first uprights 111 and two second uprights 112. The bottom support piece 1210 and the four side support pieces 1220 enclose a receiving cavity.

In some embodiments, the child's bed cover 1200 may also include a guard 1230. The protecting members 1230 are connected to the end of each side supporting piece 1220 far from the bottom supporting piece 1210, and the protecting members 1230 are sleeved on each handrail tube mechanism 120. By connecting the bottom support piece 1210 and the side support pieces 1220 to the bed frame 10, a receiving space of the child's bed 1000 can be defined, and the child can play in the receiving space. In addition, the protecting member 1230 is sleeved on the armrest pipe mechanism 120, so that the problems of collision, clamping and the like caused by the exposed armrest pipe mechanism 120 can be avoided, and the attractiveness of the child bed 1000 is improved. The protector 1230 may be made of a flexible material. For example, the protector 1230 may be a cloth cover.

In some embodiments, the side support piece 1220 is, for example, a sheet-like cloth, or a sheet-like mesh, etc., and is not particularly limited herein. Further, when the lateral support piece 1220 is a sheet-shaped mesh cloth, the lateral support piece 1220 may be regarded as being transparent, and the user may observe the child's condition in the accommodation space at any time outside the frame 10.

Further, in some embodiments, an operating member 1300 (shown in fig. 1, 2, and 41) is provided at a substantially central location of the bottom support sheet 1210. For example, the operator 1300 may be a webbing, a rope, or a loop (such as a rigid pull ring, pull handle, or hook), or the like. In this embodiment, the operating member 1300 may be a webbing tab. The operation member 1300 can be operated to switch the bed frame 10 from the unfolded state to the folded state.

When the user needs to switch the child bed 1000 from the unfolded state to the folded state, the user presses the operation end 1511 to make the locking member 151 at the unlocking position, and then, the user pulls the operation member 1300 upward or pushes or pulls the sliding member 140 along the direction F1, so that the first upright column 111 and the second upright column 112 included in the bed frame 10 can be close to each other under the cooperation of the armrest pipe mechanism 120, the top corner 130 and the sliding member 140, and the child bed 1000 can be folded.

Referring to fig. 1-4 and 41-43, in some embodiments, the cot 1000 further includes a hammock 200. Hammock 200 is removably attached to the frame 10 and is mounted within the frame 10. Of course, in some alternative embodiments, the hammock 200 can also be fixedly attached to the frame 10. In one embodiment of the present application, the hammock 200 can be received within a receiving cavity defined by the bottom support sheet 1210 and the four side support sheets 1220.

Referring to fig. 1, in one embodiment, the hammock 200 is provided with a manipulation port 201, which manipulation port 201 is positioned opposite the manipulation member 1300. When the user needs to switch the child bed 1000 from the unfolded state to the folded state, the user can make the hand pull the operation piece 1300 upwards through the operation opening 201, the operation piece 1300 moves upwards to drive the bottom support piece 1210 to fold upwards, and the bottom support piece 1210 folds to drive the four upright posts to fold, so that the child bed 1000 is switched to the folded state. When the cot 1000 is in the unfolded state, a mattress may be laid in the hammock 200 to conceal the operation opening 201 so as to carry an infant. The hammock 200 and the child's bed have smaller volumes after folding, and are convenient for storage and transportation.

Specifically, as shown in fig. 41 and 43, the hammock 200 includes a hammock cover 210 and a support member 220 that is supported on the bottom of the hammock cover 210. The hammock cover 210 includes a generally rectangular bottom cover 211 and four side covers 212 attached to the four sides of the bottom cover 211, respectively. The bottom wrap 211 and the four side wraps 212 enclose a receiving cavity 230 for receiving the mattress 300 and the infant. In this embodiment, four side wraps 212 are removably attached to four side support tabs 1220 by zippers 240. In other embodiments, the four side wraps 212 may be detachably connected to the four side support tabs 1220 by means of button fastening, velcro bonding, or the like, or directly and fixedly connected. A first opening 2111 is provided in a substantially middle position of the bottom cover 211, opposite to the operation piece 1300. In this embodiment, the hammock cover 210 is made of mesh material, so that the entire hammock 200 is more lightweight and breathable. In other embodiments, the hammock cover 210 may be formed of other lightweight, breathable, non-mesh materials.

Specifically, as shown in fig. 43 to 45, the support assembly 220 includes a pivot base 221 and a plurality of support tube sets 222 circumferentially pivoted to the pivot base 221. In the present embodiment, the pivot base 221 has a substantially circular ring structure, and a second opening 2211 is formed in the middle of the pivot base 221. The second opening 2211 is opposite to the first opening 2111 and the operation member 1300, that is, the operation opening 201 of the present application may include the second opening 2211 and the first opening 2111. The operator can operate the operation member 1300 via the second opening 2211 and the first opening 2111. The pivot mount 221 includes a first side 2212 (shown in fig. 45) facing away from the bottom cover 211 and a second side 2213 (shown in fig. 46) facing toward the bottom cover 211. The second surface 2213 of the pivot base 221 is provided with a plurality of pivot components 2214 in a ring, and each pivot component 2214 comprises two pivot components 2214a which are oppositely arranged at intervals. In the present embodiment, the number of the pivot assemblies 2214 is four, and the support tube sets 222 are correspondingly four and pivotally connected to the four pivot assemblies 2214 respectively.

Further, the length of each support tube set 222 is less than the length of each column 110 when the hammock 200 is in the expanded state. In this way, the length of each support tube group 222 is shorter, and the gravitational moment to which each support tube group 222 is subjected is smaller, so that the support stability of the whole support assembly 222 is better.

Specifically, each support tube assembly 222 includes a plurality of tube segments connected to one another, the plurality of tube segments being at least partially collapsible with one another. It should be understood that a plurality herein refers to at least two. In the present embodiment, as shown in fig. 43 to 45, each of the support tube groups 222 includes a support inner tube 2221 and a support outer tube 2222 slidably sleeved outside the support inner tube 2221. The support inner tube 2221 has a first end 2221a and a second end 2221b, and the support outer tube 2222 has a third end 2222a and a fourth end 2222b. The first end 2221a of the inner support tube 2221 is pivotally connected to the corresponding pivot assembly 2214, and the second end 2221b of the inner support tube 2221 is inserted into the outer support tube 2222 via the third end 2222a of the outer support tube 2222, so as to be slidably sleeved with the outer support tube 2222, and the fourth end 2222b of the outer support tube 2222, which is far from the pivot assembly 221, is connected to the hammock cover 210. In other embodiments, not shown, each support tube group 222 includes a first tube section, a second tube section, and a third tube section that are connected in sequence from a direction toward the pivot base 221 to a direction away from the pivot base 221, wherein the second tube section is foldable with the first tube section or the second tube section is foldable with the third tube section. Of course, the present application is not limited thereto, and the support tube group 222 may be folded by sliding or folding in other ways.

In this embodiment, as shown in fig. 43 and 44, the fourth ends 2222b of the four support tube groups 222 are respectively connected to the four top corners of the bottom cover 211. Specifically, sleeves 2112 extending toward the center of the bottom cover 211 are provided at the four top corners of the bottom cover 211, respectively. In this embodiment, the sleeve 2112 is sewn to the bottom cover 211 using the same mesh material as the bottom cover 211. The support outer tube 2222 of each support tube group 222 is inserted into the sleeve 2112, and the support outer tube 2222 is fixedly connected to the sleeve 2112 by fasteners 2113, such as blind rivets. In this embodiment, the length of sleeve 2112 is the same as the length of the supporting outer tube 2222. By the arrangement, on one hand, the extension and retraction of the support tube group 222 can be prevented from being influenced due to the overlong length of the sleeve 2112, and on the other hand, the sleeve 2112 can be ensured to have enough length, so that the support tube group 222 can be prevented from irregularly swinging along with the folding or unfolding process of the child bed 1000, and the folding and unfolding can be prevented from being influenced.

As shown in fig. 45 to 47, the support tube group 222 is switchable between an extended state and a shortened state. In the present embodiment, the extended state of the support tube group 222 refers to a state in which the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 are farthest from each other, and the shortened state of the support tube group 222 refers to a state in which the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 are closest to each other. When the support tube group 222 is in an extended state, the support inner tube 2221 extends at least partially out of the support outer tube 2222. When the support tube group 222 is in the contracted state, the support inner tube 2221 is contracted within the support outer tube 2222, i.e., the support inner tube 2221 is entirely hidden within the support outer tube 2222. Of course, in other embodiments, the support inner tube 2221 need not be entirely recessed within the support outer tube 2222, i.e., a portion of the support inner tube 2221 is recessed within the support outer tube 2222. The distance between the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 is smaller when the support tube group 222 is in the contracted state than when the support tube group 222 is in the extended state.

In this embodiment, the inner tube and the outer tube are hollow tubular structures, and the length of the support outer tube 2222 is greater than or equal to the length of the support inner tube 2221, so that when the support tube group 222 is in a shortened state, the support inner tube 2221 is fully retracted within the support outer tube 2222. In this embodiment, the length of the support outer tube 2222 is slightly longer than the length of the support inner tube 2221 to ensure that the support inner tube 2221 is maximally retracted into the support outer tube 2222. In other embodiments, the lengths of the support outer tube 2222 and the support inner tube 2221 may also be adjusted according to the size and folding condition of the child's bed. As shown in fig. 48 and 49, when the child's bed is in the collapsed state, the plurality of support tube sets 222 pivot to a position substantially below the pivot base 221 relative to the pivot base 221, and the support tube sets 222 switch to the collapsed state, so that the child's bed can have a smaller volume and is convenient for storage and transportation. The hammock 200 is mounted within the frame 10, and the hammock 200 is switchable between an expanded state and a collapsed state. One or more arm tube mechanisms 120 of the frame 10 may form a top rim 1110 of the frame 10. When the hammock 200 is in the collapsed state, the collapsed height of the support member 220 is lower than the height of the highest point of the top rim 1110. That is, the length of the support outer tube 2222 is less than or equal to the vertical distance of the bottom wrap 211 to the highest point of the top rim 1110 when the hammock 200 is in the unfolded state, so that the overall height of the cot after folding can be reduced.

The structure of one of the support members 220 is described in further detail below:

As shown in fig. 50 and 51, the support assembly 220 further includes a contact preventing assembly 223, and the contact preventing assembly 223 is provided between the support inner tube 2221 and the support outer tube 2222 to prevent direct contact therebetween. Specifically, the contact prevention assembly 223 includes a first contact prevention member 2231 disposed on the support inner tube 2221 and a second contact prevention member 2232 disposed on the support outer tube 2222, with each of the first contact prevention member 2231 and the second contact prevention member 2232 being at least partially located between the support inner tube 2221 and the support outer tube 2222.

The contact preventing assembly 223 is provided such that only the first contact preventing member 2231 is partially in contact with the support outer tube 2222, only the second contact preventing member 2232 is partially in contact with the support inner tube 2221, the support inner tube 2221 and the support outer tube 2222 are not in direct contact, the contact area is small, and sliding is smooth. And the first contact preventing member 2231 and the second contact preventing member 2232 can be made of plastic materials, so that friction between the first contact preventing member 2231 and the inner supporting tube 2221 or the outer supporting tube 2222 is reduced, and relative sliding between the inner supporting tube 2221 and the outer supporting tube 2222 is smoother.

As shown in fig. 54 and 55, the first contact-preventing member 2231 includes a first insertion portion 2231a and a first abutting portion 2231b that are connected to each other. The first insertion portion 2231a has a substantially cylindrical structure, and a first engagement finger 2231c is provided on a side wall of the first insertion portion 2231 a. The first abutting portion 2231b has a substantially truncated cone-like structure having a radial dimension larger than that of the first insertion portion 2231 a. The first abutment portion 2231b is integrally formed with the first insertion portion 2231a, and the first abutment portion 2231b closes one end of the first insertion portion 2231 a. The first abutting portion 2231b is fixed to one end of the first insertion portion 2231a and closes one end of the first insertion portion 2231 a. The support inner tube 2221 is provided with a first engagement hole 2221c. When the first contact preventing member 2231 is mounted on the support inner tube 2221, the first inserting portion 2231a is inserted into the support inner tube 2221 through the second end 2221b of the support inner tube 2221, and the first engaging finger 2231c is engaged with the first engaging hole 2221c, so as to fix the first contact preventing member 2231 and the support inner tube 2221. The first abutting portion 2231b is located outside the support inner tube 2221 and closes the second end 2221b of the support inner tube 2221. The radial dimension of the first abutment 2231b is greater than the outer diameter of the support inner tube 2221.

As shown in fig. 55, the second contact preventing member 2232 includes a second insertion portion 2232a and a second abutting portion 2232b that are connected to each other. The second insertion portion 2232a has a substantially cylindrical structure, and a second engagement finger 2232c is provided on a side wall of the second insertion portion 2232 a. The second abutting portion 2232b is a boss structure formed integrally with one end of the first insertion portion 2231 a. Or the second abutting portion 2232b is substantially a boss structure fixed to one end of the first insertion portion 2231 a. The support outer tube 2222 is provided with a second engagement hole 2222c (see fig. 48 and 49). When the second anti-contact member 2232 is mounted on the support outer tube 2222, the second inserting portion 2232a is inserted into the support outer tube 2222 through the third end 2222a of the support outer tube 2222, and the second engaging finger 2232c is engaged with the second engaging hole 2222c, so as to fix the second anti-contact member 2232 and the support outer tube 2222.

Further, as shown in fig. 50 and 51, the fourth end 2222b of the support outer tube 2222 is also provided with an end cap 224, and the end cap 224 is at least partially plugged into the support outer tube 2222 to close the support outer tube 2222.

Further, the support tube group 222 is in an extended state when the hammock 200 is in the deployed state, and the support tube group 222 is in a shortened state when the hammock 200 is in the collapsed state. When the support tube group 222 is in the extended state, as shown in fig. 51, the first abutting portion 2231b of the first contact preventing member 2231 and the second insertion portion 2232a of the second contact preventing member 2232 abut against the stopper. In this way, the maximum extension length of the support tube group 222 can be limited on the one hand, and the support inner tube 2221 can be prevented from falling out of the support outer tube 2222 on the other hand. When the hammock 200 is in the folded state, the first abutment 2231b of the first contact prevention member 2231 and the end cover 224 abut against a limit. Of course, the third end 2222a of the supporting outer tube 2222, i.e. the end of the supporting outer tube 2222, in which the second anti-contact member 2232 is inserted, may also abut against the pivot base 221 to limit.

The folding process of the child bed in this embodiment is specifically described below:

When the child bed is folded, after the locking member 151 is unlocked as described above, the four upright posts 110 are in the unlocked state, as shown in fig. 41, the operation member 1300 may be pulled upward through the first opening 2111 and the second opening 2211, so that the bottom support sheet 1210 is folded toward the operation member 1300, i.e., toward the center position, and lifted upward, and at the same time, the bottom support sheet 1210 drives the four upright posts 110 to be drawn toward the center position together. In this way, on one hand, the bottom supporting piece 1210 is folded between the four upright posts 110 in the folded state and does not fall down, and on the other hand, the bottom supporting piece 1210 lifted up can simultaneously generate an upward pushing force to the pivot base 221, so that the supporting component 220 can be folded well, that is, the supporting tube set 222 can pivot downward relative to the pivot base 221, and simultaneously is contracted to the state shown in fig. 49 under the pushing action of the bottom supporting piece 1210 and the bottom cladding 211. Then, the child's bed is gradually collapsed to the collapsed state shown in fig. 57 through the intermediate state shown in fig. 56. After folding the child's bed, the folded child's bed may be wrapped with a mattress 300 and secured by webbing 310 on the mattress 300, as shown in fig. 58. Because the hammock 200 is in the collapsed state, the collapsed height of the support member 220 is less than the height of the highest point of the top rim 1110. Therefore, the folding hammock 200 is wrapped in the child's bed, and the high point of the hammock 200 is lower than the top frame 1110, so the folding size of the child's bed is not affected by the folding hammock 200, so as to ensure that the folding volume of the child's bed is smaller.

In an embodiment not shown, the operation member 1300 may not be provided, and when the child bed is folded, the four upright posts 110 may be directly released and folded by applying an external force, and then the bottom support sheet 1210 may drop downward under the action of gravity, and at this time, the bottom support sheet 1210 needs to be manually lifted up to be folded. In the folding process, the support tube set 222 will not automatically pivot downward relative to the pivot base 221 and retract, and the support assembly 220 will prevent the folding of the entire child bed, so it is necessary to manually lift the pivot base 221 to rotate and retract the support tube set 222 relative to the pivot base 221 before continuing to fold the child bed into the folded state.

In the present embodiment, after the support tube group 222 is pivoted downward relative to the pivot base 221 during folding of the child's bed, the support inner tube 2221 of the support tube group 222 can automatically slide into the support outer tube 2222, i.e., the support tube group 222 can automatically retract, so as to achieve a folding height of the support assembly 220 lower than the height of the highest point of the top rim 1110. In other embodiments, during folding of the child's bed, after the support tube group 222 is pivoted downward relative to the pivot base 221, the support inner tube 2221 of the support tube group 222 does not automatically slide into the support outer tube 2222, and then an external force needs to be applied to slide the support inner tube 2221 into the support outer tube 2222, so that the support tube group 222 is contracted to achieve a folding height of the support assembly 220 lower than the height of the highest point of the top rim 1110.

The child's bed and hammock 200 have at least the following technical effects:

The crib comprises a bedstead and a hammock, wherein the bedstead comprises a top frame, and the hammock comprises a hammock coating and a supporting component. When the hammock is installed in the bedstead, the hammock can be switched between an unfolding state and a folding state, and when the hammock is in the folding state, the folding height of the supporting component is lower than the height of the highest point of the top frame, so that the hammock 200 has a smaller volume after being folded, and is convenient to store and transport.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
