  The following embodiments are exemplarily shown to facilitate understanding of the present invention, and the present invention can be variously modified and implemented differently from the embodiments described herein. Must understand. However, in the following description of the present invention, when it is determined that specific descriptions of related known functions or components may make the subject matter of the present invention unclear, the detailed description thereof. And concrete illustration is omitted. Also, the attached drawings are not shown to scale for assisting the understanding of the invention, and the dimensions of some components may be shown as being exaggerated.

  The baby carrier 1 according to one embodiment of the present invention operates the load adjustment unit 100 while holding the baby to appropriately transmit the weight of the baby simultaneously transmitted to the left and right shoulder bands 20a, 20b and the waist band 30. It can be dispersed in proportions. This allows the user to selectively adjust the load distribution through the load adjustment unit 100 while holding the baby so that pain does not concentrate on the shoulders and lower back due to the baby's weight.

  Hereinafter, the structure of a baby carrier according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a baby carrier according to an embodiment of the present invention, and FIGS. 2A and 2B are diagrams of the baby carrier showing a state in which the hip seat of the load adjustment unit is in the first and second positions, respectively. Side view of FIG.

  Referring to FIG. 1, a baby carrier 1 according to an embodiment of the present invention may include a body 10, left and right shoulder bands 20a and 20b, a waist band 30, a headrest 50, and a load adjustment unit 100.

  The main body unit 10 can support the baby's hips and body in a state where the user holds the baby using the baby carrier 1. The left and right shoulder bands 20a and 20b are connected to the upper side of the main body 30, and the waist band 30 is connected to the lower side.

  The left and right shoulder bands 20a, 20b may be connected to each other by the fastening member 40 while being respectively hung on the user's shoulders. The fastening member 40 is fixed to the first and second belts 42a and 42b, one end of which is connected to the left and right shoulder bands 20a and 20b, and the other ends of the first and second belts 42a and 42b, respectively. And a pair of buckles 41, 43 that can be snapped together. If the user carries the left and right shoulder bands 20a, 20b on both shoulders and wears the pair of buckles 41, 43 of the fastening member 40, the baby carrier 1 can be stably worn on the upper body. If the baby is held in this state, the baby is not easily removed from the baby carrier 1, so that it is possible to prevent the baby from falling accident.

  The upper end of the front side of the waist band 30 is connected to the main body 10, and when the baby carrier 1 is worn by the user, the waist band 30 surrounds the waist of the user. The waistband 30 may be provided with snap fasteners (not shown) such as the buckles described above to facilitate the wearing and undressing of the baby carrier 1.

  The waist band 30 may have the fixing plate 31 coupled to the inside. The fixing plate 31 is disposed substantially on the front side of the waist band 30 so as to be located below the main body portion 10. The fixed plate 31 is coupled to the load adjusting unit 100 in a detachable manner, and transmits the weight of the baby to the waist band 30 through a hip sheet 130 described later in a second posture. The fixing plate 31 and the hip sheet 130 may be made of a material having a predetermined rigidity so as to support the weight of the baby. The specific configuration of the fixing plate 31 will be described later with reference to FIGS. 3A to 4.

  A base 110 in which the load adjustment unit 100 is separably coupled to the waist band 30, and a hip seat rotating in a first position folded in the base 110 and a second position opened in such a way as to maintain an angle with the base 110 And 130, and a posture holding unit 200 which holds the position of the hip seat 130 in any one of the first posture and the second posture.

  The base 110 is detachably coupled to the front of the waist band 30. However, the base 110 is not limited thereto, and may be fixed to the front of the waist band 30.

  The base 110 is rotatably hinged to one end of the hip sheet 130 at the upper front. As shown in FIG. 2A, a state in which the hip sheet 130 is folded on the base 110 is referred to as a first posture, and as shown in FIG. 2B, a state in which the hip sheet 130 is opened so as to maintain an angle with the base 110. It is called the second attitude. The load adjusting unit 100 changes the degree of the load applied to the left and right shoulder bands 20a and 20b and the waist band 30 according to the baby's weight by taking the first position and the second position.

  In this case, most of the baby's weight acts on the left and right shoulder bands 20a, 20b than the waist band 30. If the user uses the baby carrier 1 for a long time in this state, a greater load acts on the shoulder than the user's waist, so that the shoulder can feel pain.

  In this case, if the user changes the load adjustment unit 100 to the second position while holding the baby, the hip sheet 130 receives the weight of the baby added to the main body 10 and transmits it to the waist band 30. Thereby, it is possible to reduce the load applied to the user's shoulder while the substantial part of the load acting on the left and right shoulder bands 20a and 20b is dispersed to the waist band 30.

  Conversely, if the user feels pain in the lower back by using the load adjustment unit 100 in the second position for a certain period of time, the load adjustment unit 100 is changed to the first position and the main body 10 is not supported, A substantial portion of the load applied to the waist can be distributed to the shoulders.

  In this manner, the user changes the load adjustment unit 100 to any one of the first posture and the second posture to reduce the load acting on the left and right shoulder bands 20a and 20b and the waist band 30. The ratio can be changed. As a result, it is possible to reduce pain caused at the relevant portion by preventing the weight due to the weight of the baby from concentrating on any one of the shoulder and the waist of the user.

  FIG. 3A is an exploded perspective view showing the load adjustment unit and the waist band shown in FIG. 1, and FIG. 3B is a combined perspective view of the load adjustment unit and the waist band shown in FIG. 3A. FIG. 4 is a cross-sectional view taken along the line B-B displayed in FIG. 3B.

  The waist band 30 can be provided with a fixing plate 31 for detachably fixing the load adjustment unit 100 to the waist band 30. The fixing plate 31 is disposed along the longitudinal direction of the waist band 30 so as to surround a part of the user's belly and waist on the front inner side of the waist band 30.

  The fixing plate 31 includes a plurality of coupling protrusions 34 exposed to the outside of the waist band 30 on the front surface. The plurality of coupling protrusions 34 are each formed by a pin portion 22 protruding from the fixing plate 31 and a pin portion 22 head portion 23 having a cross-sectional area larger than the cross-sectional area of the pin portion at the tip of the pin portion 22 .

  The base 110 is separably fixed to the waist band 30, and one end of the hip sheet 130 is rotatably hinged on the front surface. The base 110 may be formed with a plurality of coupling holes 111 to which the plurality of coupling projections 34 of the waist band 30 are coupled. The plurality of coupling holes 111 are formed in a shape in which circles having different radii are partially overlapped in the vertical direction. Each coupling hole 111 is formed smaller than the circle 132 formed on the upper side than the circle 132 formed on the lower side.

  The lower circle 112 of each coupling hole 111 has a diameter equal to or larger than the diameter of the head portion 33 of the coupling protrusion 34 so that the head portion 33 of the coupling protrusion 34 passes. The upper circle 113 of each coupling hole 111 has a diameter equal to or larger than the diameter of the pin portion 32 so as to be able to accommodate the pin portion 32 of the coupling protrusion 34.

  The width of the portion where the lower circle 112 and the upper circle 113 meet is formed smaller than the diameter of the pin portion 32 of the coupling protrusion 34. As a result, when the base 110 is joined to the fixing plate 31, it is possible to determine whether or not the fixing is stable with a firm sound and feeling. The coupling holes 111 serve to fix the base 110 so as not to be easily removed after the base 110 is connected to the fixing plate 31.

  The process of bonding the base 110 to the fixing plate 31 is as follows. The base 110 is moved to the front surface of the fixing plate 31 and the pin portion 22 head portion 23 of the coupling protrusion 34 passes through the lower circle 112 of the coupling hole 111, and then the base 110 is moved downward to above the coupling hole 111 The pin portion 32 of the coupling protrusion 34 is placed on the circle 113. The process of separating the base 110 from the fixing plate 31 is performed in the reverse order of the process of connecting the base 110 to the fixing plate 31.

  When the user wears the baby carrier 1, the base 110 bends to have a predetermined curvature so as to protrude toward the front side where the load adjustment unit 100 is disposed so as to correspond to the bending of the belly. Accordingly, the base 110 is in close contact with a portion of the belly and the waist of the user, and the load transmitted from the hip sheet 130 in the second posture can be substantially uniformly transmitted to the portion of the belly and the waist through the base 110. Therefore, when the user wears the baby carrier 1, the user can feel comfortable wearing.

  In the hip seat 130, inclined portions 131 and 133 are provided at both sides of the central portion 132, and inclined at predetermined angles. Thereby, the inclined portions 131 and 133 can naturally support the baby's foot in the second posture. Also, in the first position, both sides of the hip seat should not protrude so that the baby's body (foot or thigh) will not touch.

  Referring to FIG. 4, a dispersion plate 35 supporting the lower end of the base 110 is disposed outside the waist band 30. The baby's weight applied to the hip sheet 130 in the second position is transmitted to the base 110. As a result, the base 110 is about to rotate in the counterclockwise direction with the coupling protrusion 111 as a reference point. Thereby, the lower end portion of the base 110 presses the front surface of the waist band 30. In this case, there is a problem that the load is concentrated on the portion of the waist band 30 which is in contact with the edge of the lower end of the inclined base 110. In order to disperse such concentrated load, one end 35a supports the lower end portion of the base 110 outside the waist band 30, and the other end 35b may dispose the dispersion plate 35 fixed to the waist band 30. it can. The dispersion plate 35 is spaced apart from the fixed plate 31.

  The dispersion plate 35 supports a portion hinged to the hip sheet 130 of the base 110 and a portion farthest away. In order for the dispersion plate 35 to support the lower end portion 116 of the base 110, the lower end portion 116 of the fixing plate 31 is formed with a concave arrangement groove 37 for arranging the dispersion plate 35. The arrangement groove 37 is formed larger than the dispersion plate 35. Thereby, the dispersion plate 35 and the fixing plate 31 are disposed apart from each other.

  When the lower end portion 116 of the base 110 is inclined toward the waist band 30, the dispersion plate 35 supports the lower portion of the base 110. This makes it possible to prevent concentration of force at any one point while the lower end portion 116 of the base 110 is inclined. The dispersion plate 35 can disperse the load concentrated on the edge of the inclined lower end portion 116 of the base 110. As indicated by the arrows in FIG. 4, the load applied to the hip sheet 130 is dispersed by the distribution plate 35 and acts on the user. This can reduce the pain applied to the user's abdomen.

  The posture holding unit 200 includes various embodiments, which will be described with reference to the following drawings.

  The insertion portion 255 is selectively inserted into any one of the first and second locking grooves 220 and 230 by changing the load adjustment unit 100 to the first or second position. When inserted into any one of the first and second locking grooves 220 and 230, the insertion portion 255 fixes the hip sheet 130 positioned in the first or second posture, and the first and second locking grooves. When the user comes out of the positions 220 and 230, the hip sheet 130 can be changed from any one of the first and second postures to one remaining posture.

  The elastic member 253 elastically supports the shaft portion 251 inside a part of the hinge portion 150. The elastic member 253 may be formed of a coil spring into which the shaft portion 251 is inserted. The elastic member 253 exerts an elastic force in the direction of pressing the locking shaft 250 to the locking rib 270 side. Thus, the locking shaft 250 can move linearly along a direction substantially perpendicular to the surface of the locking rib 270 in which the first and second locking grooves 220 and 230 are formed.

  The locking handle 257 pulls the insertion portion 255 out of the second locking groove 230 by pulling in a direction away from the locking rib 270 in the second posture. As a result, the hip sheet 130 is released from the state of being held open and folded into the base 110.

  Referring to FIGS. 7B and 7C, the process of changing the hip seat 110 of the load adjustment unit 100 from any one of the first posture and the second posture to the remaining one of the first posture and the second posture. To explain.

  As shown in FIG. 7B, the hip seat 130 is folded into the first posture base 110. In the first position, the baby's weight is placed on the main body portion 10 of the baby carrier 1 and the left and right shoulder bands 20a, 20b are pulled downward. In this case, the load applied to the left and right shoulder bands 20 a and 20 b by the baby's weight is greater than the load applied to the waist band 30.

  When the user uses the baby carrier 1 for a long time with the load adjustment unit 100 set in the first posture, pain can be felt on the shoulder. In this case, the user can reduce the pain applied to the shoulders by changing the load adjustment unit 100 from the first position to the second position through simple operation and transmitting a considerable portion of the load applied to the shoulders to the waist. .

  In order to change the load adjustment unit 100 from the first position to the second position, the user simply rotates the hip sheet 130 in the direction to be opened from the base 110, and the fixation to the hip sheet 130 in the first position is released. Be done.

  Then, when the user rotates the hip sheet 130 in the opening direction, the insertion portion 255 of the locking shaft 250 comes out of the fixing portion 225 of the first locking groove 220 and slides along the cam surface 223 to lock it. Exit the groove 220. Subsequently, the insertion portion 255 slides on one surface 270 a of the locking rib 270 which rotates with the hip seat 130.

  When the hip seat 130 is in the fully open second position, the insertion portion 255 of the locking shaft 250 is inserted into the second locking groove 230 as shown in FIG. 7C. Thereby, the hip seat 130 is fixed in the open state.

  When the load adjustment unit 100 is converted from the first position to the second position, the weight of the baby placed on the main body 10 is transmitted to the waist band 30 through the hip sheet 130, thereby the left and right shoulder bands 20a. 20b, the load applied to the user's shoulder is distributed to the waistband 30. Thus, the load applied to the waistband 30 acts more than the loads applied to the left and right shoulder bands 20a, 20b.

  Thus, by switching the load adjustment unit 100 from the first position to the second position, the user can reduce the pain applied to the shoulder.

  On the other hand, if the baby carrier 1 is used for a long time in a state where the load adjustment unit 100 is set in the second posture, pain in the waist can be felt. In this case, the pain in the lower back can be alleviated by rapidly changing the load adjustment unit 100 from the second posture to the first posture. Hereinafter, the process of switching the load adjustment unit 100 from the second posture to the first posture will be described.

  If the user pulls the locking handle 257 in the direction of the arrow shown in FIG. 6 to change the load adjustment unit 100 from the second position to the first position, the user of the locking shaft 250 inserted in the second locking groove 230. The insertion portion 255 comes out of the second locking groove 230. In this state, when the hip sheet 130 is rotated in the folding direction, the insertion portion 235 slides along the cam surface 223 of the first locking groove 220 while sliding while pressing the one surface 270 a of the locking rib 270 by the elastic member 253. And inserted into the first locking groove 230. If the insertion portion 235 is inserted into the fixing portion 225 of the first locking groove 230 while sliding along the cam surface 223 of the first locking groove 220, the hip sheet 130 is folded to the base 110 and the load adjusting unit 100 is assembled. Is changed to the first attitude.

  Meanwhile, a load control unit according to an embodiment of the present invention has a posture holding unit with various structures, and various embodiments of the load control unit will be described with reference to attached FIGS. 8 to 17C.

  As can be seen through FIGS. 8-17C, the basic structure of the load adjustment unit is similar to that of the embodiment of the invention described above. Therefore, the same parts and configurations as those in the embodiment described above are assigned the same reference numerals and quoted.

  FIG. 8 is a front view showing a load adjustment unit holding a second posture by another locking structure, and FIG. 9A is a front view showing a load adjustment unit holding a first posture by another locking structure. FIG. 9B is a cross-sectional view taken along the line FF shown in FIG. 9A, and FIG. 9C is a cross-sectional view taken along the line EE shown in FIG.

  Referring to FIGS. 8 to 9C, the posture holding unit 300 capable of operating the load adjustment unit 100 to change to the first or second posture is slidably disposed on the hip sheet 130 in a resilient manner. A locking shaft 350, and first and second locking grooves 320, 330 formed on the base 110 and to which the locking shaft 350 is fixably coupled.

  The locking shaft 350 of the posture maintaining unit 300 of the load adjustment unit 100 according to another embodiment of the present invention shown in FIG. 8 is formed in the hip sheet 130, and the first and second locking grooves 320, 330 have a base 110. Is formed. A locking shaft 250 is formed in the base 110, and the first and second locking grooves 220, 230 differ from the locking structure of the embodiment of FIG. 6 formed in the hip sheet 130.

  The base 110 includes a hinge hole 153 and a locking rib 370 in which first and second locking grooves 320 and 330 are formed. The locking rib 370 is protruded toward the hip seat 130 at the top of the base 110. The locking rib 370 is formed on the outer surface of the base 110, and the locking rib 370 is formed symmetrically on both upper sides of the base 110.

  The locking shaft 350 can move linearly along a direction perpendicular to the surface of the locking rib 370. The locking shaft 350 is elastically movable in the locking shaft housing 380 by an elastic member 353 described later. The locking shaft housing 380 is formed in the hip seat 130, and the locking shaft housing 380 is disposed adjacent to the surface of the locking rib 370.

  The first locking groove 320 and the second locking groove 330 are formed on one surface 370a of the locking rib at a predetermined distance from each other. One surface 370 a of the locking rib is a surface adjacent to the locking shaft receiving portion 380.

  The first and second locking grooves 320 and 330 are spaced apart from each other, and are disposed at positions where the locking shaft 350 is inserted according to the first and second postures in which the hip sheet 130 is folded or opened on the base. Ru. Accordingly, the locking shaft 350 is inserted into the first locking groove 320 when the hip seat 130 is in the first posture in which the hip seat 130 is folded to the base 110, and the hip seat 130 is opened at a predetermined angle with respect to the base 110. When positioned in the second position, the second locking groove 330 is inserted. As such, when the locking shaft 350 is inserted into the first or second locking groove 320, 330, the first or second position may be maintained.

  The first locking groove 320 is located above the second locking groove 330.

  Specifically, when the hip seat 130 maintains the second position, the locking shaft 350 is inserted into a second locking groove 330 formed on the lower side of the locking rib 370.

  The first locking groove 320 and the second locking groove 330 are formed to have a depth in which the insertion portion 355 of the locking shaft 350 is inserted. The first locking groove 320 and the second locking groove 330 are formed in a cylindrical shape corresponding to the insertion portion 355 of the locking shaft 350. The diameters of the first and second locking grooves 320 and 330 may be equal to or slightly larger than the diameter of the locking shaft 350.

  The locking shaft 350 may include a shaft 351, an insertion portion 355 and a locking handle 357. The shaft portion 351 is slidably provided in a part of the locking rib 370. The insertion portion 355 is extended to one end of the shaft portion 351 and selectively inserted into the first and second locking grooves 320 and 330. The other end of the shaft 351 is coupled with a locking handle 357 for the user to move the shaft 351.

  The insertion portion 355 is selectively inserted into any one of the first and second locking grooves 320 and 330 by changing the load adjustment unit 100 to the first or second position. When inserted into any one of the first and second locking grooves 320 and 330, the insertion portion 355 fixes the hip sheet 130 positioned in the first or second posture, and the first and second locking grooves. When the user goes out of 320 and 330, the hip seat 130 can change from any one of the first and second postures to one remaining posture.

  The elastic member 353 elastically supports the shaft portion 351 inside a part of the shaft housing portion 380. The elastic member 353 may be formed of a coil spring into which the shaft 351 is inserted. The elastic member 353 exerts an elastic force in a direction to press the locking shaft 350 toward the locking rib 370. Accordingly, the locking shaft 350 can move linearly along a direction substantially perpendicular to the surface of the locking rib 370 in which the first and second locking grooves 320 and 330 are formed.

  The locking handle 357 pulls the insertion portion 355 from the second locking groove 330 by pulling in a direction away from the locking rib 370 in the second position. As a result, the hip sheet 130 is released from the state of being held open and folded into the base 110.

  The locking shaft 350 is arranged to be exposed to the outside when the hip seat 130 is opened to the second position. The locking shaft 350 must move in the direction of the arrow to change the attitude of the hip seat 130. Since the locking handle 357 is exposed to the outside when the hip seat 130 is opened, there is an easy advantage when the user changes the hip seat 130 from the second posture to the first posture.

  When the load adjustment unit 100 is changed from the first position or the second position to the remaining position, the insertion portion 355 is disengaged from the first locking groove 320 or the second locking groove 330. Subsequently, the insertion portion 355 rotates with the hip seat 130 while sliding on one surface 370 a of the locking rib 370. At this time, when the insertion portion 355 exerts an elastic force in the direction of the locking rib 370 by the elastic member 353 and the hip sheet 130 is positioned in the first position or the second position, the insertion portion 355 is in the first locking groove 320. Or inserted into the second locking groove 330.

  Specifically, as shown in FIG. 9B, when the hip sheet 130 is in the first position, the insertion portion 355 is inserted into the first locking groove 320, and as shown in FIG. 9C, the hip sheet 130 is in the second position. The insertion portion 355 is inserted into the second locking groove 330.

  In the load adjustment unit 100 according to another embodiment of the present invention, in the first position, the locking unit 300 is disposed at a portion where the base 110 and the hip sheet 130 are hingedly connected. Thus, the locking handle 357 can be shielded by the hinge 150 of the baby carrier 1. If the hinge part 150 is arranged to shield the connection part of the load adjustment unit 100, the load adjustment unit 100 has an effect of appearing clean.

  When the load adjustment unit 100 maintains the first position, the locking shaft 350 is inserted into the first locking groove 320. The locking shaft 350 is inserted into a first locking groove 320 formed on the upper side of the locking rib 370 while the hip seat 130 is folded.

  Since the first locking groove 320 is formed in a shape corresponding to the insertion portion 355 of the locking shaft 350, the first locking groove 320 locks the locking shaft 350 to unlock the hip seat 130 fixed in the first position. It must be removed from the groove 320.

  Referring to FIGS. 9B and 9C, the process of changing the hip seat 130 of the load adjustment unit 100 from any one of the first posture and the second posture to the remaining one of the first posture and the second posture. To explain.

  As shown in FIG. 9B, the hip seat 130 is folded into the first posture base 110. To change the load adjustment unit 100 from the first position to the second position, the user pulls the locking shaft 350 in the direction of the arrow shown in FIG. 9A. When the locking handle 357 is pulled in the direction of the arrow, the insertion portion 355 of the locking shaft 350 comes out of the first locking groove 320. If the hip sheet 130 is rotated in the open direction in this state, the insertion portion 355 is inserted into the second locking groove 330 while sliding while pressing the one surface 370 a of the locking rib 370 by the elastic member 353.

  When the hip seat 130 is in the fully opened second state, as shown in FIG. 9C, the insertion portion 355 of the locking shaft 350 is inserted into the second locking groove 330. By inserting the locking shaft 350 into the second locking groove 330, the hip seat 130 is fixed to hold the second position.

  The user moves the locking shaft 350 in the arrow direction shown in FIG. 8 in order to change the load adjustment unit 100 from the second position to the first position. When the locking handle 357 is pulled in the direction of the arrow, the insertion portion 355 of the locking shaft 350 comes out of the second locking groove 330. In this state, when the hip sheet 130 is rotated in the folding direction, the insertion portion 355 is inserted into the first locking groove 320 while sliding while pressing the one surface 370 a of the locking rib 370 by the elastic member 353.

  FIG. 10 is a front view showing a load adjustment unit holding a second posture by still another locking structure, and FIG. 11A is a front view showing a load adjustment unit holding a first posture by another locking structure is there. 11B is a cross-sectional view taken along the line HH shown in FIG. 11A, and FIG. 11C is a cross-sectional view taken along the line G-G shown in FIG.

  Referring to FIGS. 10 to 11C, the posture maintaining portion 400 of the load adjustment unit 100 according to another embodiment of the present invention has a first locking groove 420 located below the second locking groove 430 and a first locking groove 400. Second locking grooves 420 and 430 are included. Specifically, the first locking groove 420 for fixing the hip sheet 130 in the first position is located below the second locking groove 430 for fixing the hip sheet 130 in the second position.

  The load adjusting unit according to still another locking structure shown in FIG. 10 is different from the embodiment of FIG. 8 in which the first locking groove 420 is formed above the second locking groove 430.

  When the hip seat 130 of the load adjustment unit 100 according to another embodiment of the present invention is fixed in the second position, as shown in FIG. 11C, the locking shaft 450 is a second locking formed above the hinge hole 153. The groove 430 is inserted. Thus, when the hip seat 130 is in the second position, the locking shaft 450 is not exposed to the outside. The locking shaft 450 is disposed on the outer surface of the hip seat 130.

  Since the locking handle 457 is not exposed to the outside in the second position, there is an advantage that the risk of the hip seat 130 being unlocked in the second position is reduced due to the user's erroneous operation.

  The locking portion 400 of the load adjustment unit 100 according to another embodiment of the present invention is exposed to the outside in order to be disposed on the outer surface of the hip seat 130 in the first position.

  When the load adjustment unit 100 maintains the first position, the locking shaft 450 is inserted into the first locking groove 420 as shown in FIG. 11B. The locking shaft 450 is inserted into a first locking groove 420 formed below the hinge hole 153 of the fixing bracket 470 when the hip seat 130 is folded.

  The first locking groove 420 is configured to first lock the locking shaft 450 in order to unlock the hip seat 130 fixed in the first position so that the first locking groove 420 is formed in a shape corresponding to the insertion portion 455 of the locking shaft 450. It must be pulled out of the groove 420.

  The user can pull the locking handle 457 in the direction of the arrow shown in FIG. 16 to unlock the hip seat 130 fixed in the first position. The locking handle 457 is exposed to the outside in the first position, which facilitates the user's access. Thus, the user can easily change the posture of the load adjustment unit 100.

  The process of changing the hip seat 130 of the load adjustment unit 100 from any one of the first posture and the second posture to the remaining one of the first posture and the second posture is the same as that of the embodiment of FIG. So, the explanation about this is omitted.

  FIG. 12 is a front view showing the load adjustment unit holding the second position through the support member, and FIG. 13A is a front view showing the load adjustment unit holding the first position through the support member. 13B is a cross-sectional view taken along the line JJ shown in FIG. 13A, and FIG. 13C is a cross-sectional view taken along the line I-I shown in FIG.

  Referring to FIGS. 12 to 13C, one side of the base 110 may be operated to change the load adjustment unit 100 to the first or second position with the hip seat 130 in the second position. A posture holding unit 500 can be provided.

  The posture holding unit 500 includes a support member 510 which is hinged at one end to the hip seat and holds the hip seat in an open state with respect to the base in the second posture.

  One end 512a, 512b of the support member 510 is hingedly connected to the hip sheet 130, and the other end 514 of the support member 510 is separably fixed to the hip sheet 130 in the first position, and is base 110 in the second position. The support member 510 is formed in a “U” shape, and one end 512 a, 512 b of the support member 510 is rotatably inserted into an insertion groove 511 formed in the hip sheet 130. The support member 510 is rotatable from the opened hip seat 130 to the base 110. The other end 514 of the hip sheet 130 is placed in a support groove 513 formed in the base 110.

  One end of the support member 510 may be disposed on the hip sheet 130, and the other end of the support member 510 may be placed on the base 110 to fix the hip sheet 130 in the second position.

  When the load adjustment unit 100 is in the first position, as shown in FIG. 13B, one end 512a, 512b of the support member 510 is hingedly connected to the hip sheet 130, and the other end 514 of the support member 510 is connected to the hip sheet 130. It is separably fixed to the formed accommodation groove 515.

  When the load adjustment unit 100 is in the second position, as shown in FIG. 13C, one end 512a, 512b of the support member 510 is hinged to the hip sheet 130, and the other end 514 of the support member 510 is formed on the base 110. Is placed on the support groove 513.

  First and second snap coupling members 535 are disposed at a hinge 150 where the hip seat 130 and the base 110 are hingedly connected. The first and second snap coupling members 531 and 535 are disposed on the hinge shaft 151. The first snap coupling member 531 is disposed on the hip seat 130, and the second snap coupling member 535 is disposed on the base 110. The first snap coupling member 531 and the second snap coupling member 535 are disposed adjacent to each other.

  The first snap coupling member 531 is disposed in a snap coupling housing 515 formed in the hip sheet 130 and is disposed between the elastic member 533 and the second snap coupling member 535. The elastic member 533 is disposed on a surface of the first snap coupling member 531 not adjacent to the second snap coupling member 535. The elastic member 533 has an elastic force in the direction in which the first snap coupling member 531 presses the second snap coupling member 533. Accordingly, the first snap coupling member 531 pressurizes the second snap coupling member 535 when the first snap coupling member 531 rotates with the hip sheet 130. One end of the first snap coupling member 531 contacts the elastic member 533, and the other end of the first snap coupling member 531 contacts the second snap coupling member 535. The other end of the first snap coupling member 531 is formed with a plurality of outwardly protruding protrusions 532.

  The second snap coupling member 535 is disposed fixed to the hinge shaft 151. The second snap coupling member 535 is disposed at a hinge 150 formed on the base 110. At one end of the second snap coupling member 535 in contact with the first snap coupling member 531, a groove 536 is formed which can be coupled to the protrusion 532 of the first snap coupling member 531. The protrusion 532 and the groove 536 are formed to mesh with each other in the first position or the second position.

  The first and second snap coupling members 535 are snapped to each other in the first position or the second position. If the hip seat 130 rotates in the first or second posture, the rotation of the hip seat 130 causes the first snap coupling member 531 to rotate. Thereby, the coupling of the first and second snap coupling members 531 and 535 is released. When the rotated hip sheet 130 is again in the first or second position, the first and second snap coupling members 531 and 535 are snapped to each other.

  When the hip sheet 130 is changed from the first position to the second position, the rotation of the hip sheet 130 causes the first snap coupling member 531 to rotate with the hip sheet 130. In the first posture state of the hip sheet 130, the first and second snap coupling members 531 and 535 are snap-connected to each other, but when the first snap coupling member 531 is rotated, the protrusions of the first snap coupling member 531 Grooves 536 of 532 and second snap coupling member 535 are not coupled to each other. As a result, the first snap coupling member 531 linearly moves in the direction opposite to the surface adjacent to the second snap coupling member 535. That is, the first snap coupling member 531 moves in the direction in which the elastic member 533 is disposed. The surface on which the hip seat 130 is in the second position, the first and second snap coupling members 535 are snapped to each other.

  When changing the hip sheet 130 of the load adjustment unit 100 from the first position to the second position, the user simply rotates the hip sheet 130 in the direction to be opened, thereby releasing the fixing of the hip sheet 130 in the first position. Be done.

  When the hip sheet 130 is in the second position, the first and second snap coupling members 535 may be snapped together to temporarily fix the hip sheet 130 in the second position. When the user separates the other end 514 of the support member 510 from the hip sheet 130 and places it in the support groove 513 of the base 110, the other end 514 of the support member 510 is placed on the base 110 to hold the hip sheet 130. It can be fixed in 2 postures. The support member 510 supports the hip seat 130 in the second position.

  When the load adjustment unit 100 is changed from the second posture to the first posture, the user separates the other end 514 of the support member 510 placed on the base 110 from the support groove 513, and the accommodation groove 515 of the hip sheet 130. Fix it to The other end 514 of the support member 510 is moved to the hip seat 130 to unlock the hip seat 130 fixed in the second position. The hip seat 130 that has been unlocked is folded in the first position.

  When the hip sheet 130 is in the first position, the first and second snap coupling members 535 may be snapped to each other to temporarily fix the hip sheet 130 in the first position. The fixing force by the first and second snap coupling members 535 is such that the fixing is released when the user opens the hip sheet 130 by hand.
