  Here, the living space of the baby sitting on the seat 60 described above is mainly defined by the seat portion 65, the back portion 70, and the side frame members 73 of the seat 60. As described above, the side frame members 73 are connected to the side support portions 72 connected to the base 61. Here, if the distance between the pair of bases 61 is increased to expand the living space, the distance between the pair of first link members 21 disposed on both sides of the base 61 and the pair of front legs 30 The distance between the pair of rear legs 35 and the like also increases, and the vehicle width of the stroller 10 increases. However, the width of the baby carriage 10 has certain restrictions depending on the usage environment of the baby carriage 10 and the like. Therefore, in the illustrated example, a device is devised to secure a wide living space while suppressing the width of the baby carriage 10.

  Specifically, as shown in FIG. 10, the pair of side support portions 72 are inclined outward in the width direction from the corresponding base portions 61 upward. More specifically, the upwardly extending portions 72a of the pair of side support portions 72 extend upward and outward in the width direction from the base bodies 61a of the corresponding base portions 61, and face upward in a front view (front view). The shape of the letter spreads out. Therefore, the rear connecting portion 72b connected to each of the upper extending portions 72a is located outside in the width direction from the end of the upper extending portion 72a on the base body 61a side. By connecting the side frame members 73 to the rear connection portion 72b, the side frame members 73 are extended as compared with the case where the pair of side support portions 72 extend vertically upward from the base. The dimension W1 in the width direction of the region surrounded by is expanded. Thereby, the living space defined by the seat portion 65, the back portion 70, and the side frame members 73 is also expanded.

  Particularly, in the illustrated example, the width direction dimension W1 of the region surrounded by the side frame member 73 is larger than the width direction dimension W2 of the back portion 70. Therefore, the side wall formed by the side frame member 73 and the back part 70 on the side of the baby sitting on the seat 60 is inclined outward from the back part 70 in the width direction. Thereby, the space for the infant sitting on the seat 60 to move the limbs and upper body is expanded.

  In the illustrated example, the side support portion 72 extends above the first link member 21 in a state where the seat 60 is held by the stroller main body 20, as is well shown in FIG. . Here, in the illustrated example, as will be described later, even if the baby carriage main body 20 is folded while holding the seat 60, the side support portions 72 do not interfere with the pair of first link members 21 so that the side support portions Reference numeral 72 is located on the inner side in the width direction of the inner side surfaces of the pair of first link members 21 facing each other. However, the present invention is not limited to this, and the side support portions 72 may extend outward in the width direction from the inner side surfaces of the pair of first link members 21. Particularly in the illustrated example, the seat 60 is detachably held by the stroller body 20. Therefore, when the seat 60 is to be removed when the baby carriage main body 20 is folded, the side support portions 72 extend outward in the width direction from the inner side surfaces of the pair of first link members 21. May be.

  In FIG. 8, illustration of the seat plate 68, the guard member 76, the top support member 77, and the like is omitted.

  Next, the holding member 50 provided on the stroller main body 20 to hold the seat 60 will be described. As shown in FIG. 6, a pair of holding members 50 are provided at positions between the pair of first link members 21 in the width direction. The pair of holding members 50 are arranged apart from each other in the width direction. As shown in FIG. 1, the seat 60 is held by the pair of holding members 50 at a position between the pair of first link members 21 in the width direction.

  The holding member 50 has a support portion 53 that supports the supported portion 63 provided on the seat 60. The support portion 53 can be formed as a receiving hole that opens upward, or an insertion portion that projects upward. In addition, the supported portion 63 can be configured as a downwardly projecting insertion portion that can be inserted into the receiving hole of the supporting portion 53 or a downwardly opened receiving hole that can insert the inserting portion of the supporting portion 53. In the illustrated example, the holding member 50 has, as the support portion 53, a receiving hole formed in the support surface 52 facing upward. The support surface 52 extends in the front-rear direction. In other words, a receiving hole as a support portion 53 is formed at the center of the support surface 52 that extends in the front-rear direction. The support surface 52 faces upward, and the receiving hole forming the support portion 53 opens upward.

  On the other hand, in the seat 60, a pair of bases 61 arranged apart from each other in the width direction has a supported portion 63. That is, a pair of holding members 50 are provided separately from each other in the width direction corresponding to the respective bases 61. The supported surface 62 is provided on the base body 61a and faces downward. The supported surface 62 extends in the front-rear direction corresponding to the support surface 52. An insertion portion forming the supported portion 63 protrudes downward from a center portion of the supported surface 62 in the front-rear direction.

  According to such a configuration of the support portion 53 and the supported portion 63, the seat 60 can be held on the front leg 30 via the holding member 50 by lowering the seat 60 onto the baby carriage main body 20 from above in the vertical direction. It becomes possible. More specifically, when the seat 60 is lowered, the supported portions 63 projecting downward from each of the pair of base portions 61 are inserted into the corresponding support portions 53 of the holding member 50. Then, the seat 60 is held on the stroller body 20 by the contact of the supported surface 62 of the base body 61 a with the support surface 52 of the holding member 50. Since the support portion 53 is engaged with the supported portion 63 while the seat 60 is held by the stroller main body 20, the relative movement of the seat 60 to the stroller main body 20 in the horizontal direction is restricted.

  Further, the pair of holding members 50 and the pair of bases 61 are arranged apart from each other in the width direction. Therefore, in a state where the seat 60 is held by the stroller main body 20, the displacement caused by the relative rotation of the seat 60 and the stroller main body 20 about the axis along the front-rear direction, and the seat about the axis along the vertical direction The displacement due to the relative rotation of the stroller body 60 and the stroller body 20 can be effectively regulated. In addition, as shown in FIGS. 6 and 8, the support surface 52 extends forward and backward in the support portion 53, and the supported surface 62 of the base body 61 a extends before and after the supported portion 63. Therefore, in a state where the seat 60 is held by the stroller main body 20, the displacement due to the relative rotation of the seat 60 and the stroller main body 20 about the axis along the width direction can be effectively controlled. From the above, the seat 60 provided on the stroller main body 20 can stably hold the seat 60.

  In the illustrated example, the stroller main body 20 has a link structure for allowing a folding operation. These link structures include a pair of configurations symmetrical about the center plane in the width direction and separated from each other in the width direction. The pair of holding members 50 are disposed between the pair of components, and the seat 60 is held between the pair of components. Specifically, the seat 60 is held between the pair of first link members 21, between the pair of front legs 30, between the pair of rear legs 35, and between the pair of handle extension portions 42. Such an arrangement of the seat 60 makes it possible to avoid interference with the components of the stroller main body 20. That is, the holding member 50 can hold the seat 60 such that the seat 60 is separated from the baby carriage main body 20. Therefore, as shown in FIG. 9, the direction of the seat 60 held by the stroller main body 20 via the holding member 50 can be changed. Thereby, the infant shown in FIG. 9A is turned forward in the traveling direction of the stroller 10 only by changing the orientation of the seat 60, and the infant shown in FIG. It is possible to switch between the face-to-face state facing the operator (guardian). Further, such an arrangement of the seat 60 can also avoid interference between the stroller main body 20 and the seat 60 during the folding operation. Therefore, as shown in FIG. 3, the stroller main body 20 can be folded while holding the seat 60. In the illustrated baby carriage 10, the baby carriage 10 can be folded while the seat 60 is held by the baby carriage main body 20 in any of the facing state and the back state.

  Further, as shown in FIG. 8, the seat 60 has a protrusion 64 urged inward in the width direction from each supported portion 63. As shown in FIG. 6, in the holding member 50, a protrusion receiver 54 that receives the protrusion 64 is formed on a wall portion in the width direction of a wall portion that forms the support portion (receiving hole) 53. The projection 64 is automatically buried inside the supported portion 63 when the supported portion 63 is inserted into the supporting portion 53 because the lower side surface is inclined. When the projection 64 reaches a position facing the projection receiver 54, the projection 64 is fitted into the projection receiver 54 by an urging force from an urging unit (not shown). That is, by inserting the supported portion 63 into the support portion 53, the seat 60 is fixed to the holding member 50.

  As shown in FIG. 6, the holding member 50 has a projection release unit 55 at a position facing the projection receiver 54. The protrusion releasing means 55 protrudes inward in the width direction from the holding member 50. By pushing the projection releasing means 55 outward in the width direction, the projection 64 fitted in the projection receiver 54 can be pushed out from the projection receiver 54. That is, when the seat 60 is detached from the stroller main body 20, the fixing by the fixing means constituted by the projection 64 and the projection receiver 54 can be released by operating the projection releasing means 55.

  Next, the mounting structure and the mounting position of the holding member 50 to the baby carriage main body 20 will be described.

  In the present embodiment, as shown in FIG. 7, each holding member 50 is connected to a plurality of connection positions JPX and JPY of the baby carriage main body 20 that are separated from each other. As a result, in the illustrated example, each holding member 50 is fixed to the stroller main body 20 and is stably held by the stroller main body 20. Further, the support portion 53 of the holding member 50 is located above one connection position JPX of the stroller main body 20. Therefore, the weight of the seat 60 held by the holding member 50 can be stably and efficiently supported by the stroller body 20. Thereby, the play of the holding member 50 with respect to the baby carriage main body 20 can be effectively reduced. Further, since it is not necessary to increase the size of the holding member 50 or to provide a large number of holding members 50, the design of the baby carriage 10 can be improved.

  In the illustrated example, first, each holding member 50 is connected to the handle extension portion 42 at the rotation axis AR1 between the second link member 22 and the handle extension portion 42. As a specific configuration, as shown in FIGS. 6 and 7, each holding member 50 is connected to a main shaft member 25 that rotatably connects the second link member 22 and the handle extension 42. That is, in the illustrated example, the first connection position JPX of the holding member 50 to the stroller main body 20 is the main shaft member 25. The main shaft member 25 passes through the holding member 50. The main shaft member 25 further penetrates the second link member 22 and the third link member 23. Therefore, the holding member 50 is connected not only to the handle extension 42 of the handle 40 but also to the second link member 22 and further to the third link member 23 via the main shaft member 25.

  Further, each holding member 50 is connected to a reinforcing connection member 45 of the handle 40. The reinforcing connecting member 45 is connected to the handle extension 42 as a part of the handle 40. That is, in the illustrated example, the second connection position JPY of the holding member 50 to the stroller main body 20 is the reinforcing connecting member 45. As shown in FIG. 7, the holding member 50 has a through hole 56 through which the reinforcing connection member 45 passes. The cross-sectional shape of the reinforcing connecting member 45 is somewhat flattened from a circular shape. The through hole 56 of the holding member 50 is also somewhat flat. Therefore, the relative rotation of the holding member 50 with respect to the stroller main body 20 about the axis along the width direction is restricted by the reinforcing connecting member 45 penetrating through the through hole 56 of the holding member 50.

  In such a stroller 10, the first connection position JPX of the holding member 50 to the stroller main body 20 is the main shaft member 25, which is connected to a lower portion of the holding member 50. Then, as shown in FIG. 7, the support portion 53 of the holding member 50 is disposed at a position displaced upward from the main shaft member 25 in the up-down direction. Therefore, the weight of the seat 60 held by the holding member 50 can be efficiently supported by the stroller body 20 without increasing the size of the holding member 50 or providing a large number of holding members 50.

  Further, a second connection position JPY of the holding member 50 to the stroller main body 20 is a reinforcing connection member 45 and is connected to a rear portion of the holding member 50. Therefore, as shown in FIG. 7, the holding member 50 faces the reinforcing connecting member 45 from the front along the front-rear direction. The support portion 53 of the holding member 50 is disposed at a position shifted forward from the reinforcing connection member 45 in the front-rear direction. Therefore, the stroller main body 20 can efficiently and stably receive the inertial force from the seat 60 during forward movement via the holding member 50. Thereby, the occurrence of rattling of the holding member 50 with respect to the baby carriage main body 20 can be more effectively suppressed.

  Furthermore, if the distance between the two connection positions JPX and JPY of the stroller main body 20 is close, the holding member 50 will easily rattle against the stroller main body 20. On the other hand, if the vertical insertion length IL of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60 along the vertical direction is long, the rattling of the seat 60 with respect to the holding member 50 is effectively suppressed. be able to. On the other hand, if the insertion length IL is long, a large force is applied to the holding member 50, and the holding member 50 is likely to rattle to the stroller main body 20. In this regard, as shown in FIG. 7, the separation distance D between the two connection positions JPX and JPY is longer than the vertical insertion length IL of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60. It is getting longer. This also makes it possible to more effectively suppress the occurrence of rattling of the holding member 50 with respect to the stroller main body 20.

  In addition, in order to efficiently support the force applied to the holding member 50 by the stroller body 20, the distances D1 and D2 from the support portions 53 of the holding member 50 to the connection positions JPX and JPY to the stroller body 20 are reduced. Is effective. The distance from the support portion 53 of the holding member 50 to any one of the connection positions JPX, JPY, in particular, the shortest distance between the support portion 53 of the holding member 50 and any one of the connection positions is determined by the support portion 53 and the supported position. It is preferable that the insertion length IL of the portion 63 in the vertical direction is shorter than the insertion length IL. In the illustrated example, the shortest distance from the support portion 53 of the holding member 50 to any of the connection positions JPX and JPY is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63. ing. That is, as shown in FIG. 7, the shortest distance D1 between the support portion 53 and the first connection position JPX is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63, and The shortest distance D1 between the support portion 53 and the second connection position JPY is shorter than the vertical insertion length IL of the support portion 53 and the supported portion 63 in the vertical direction.

  Particularly, in the illustrated example, the distance D1 along the vertical direction from the support portion 53 to the first connection position JPX located below the support portion 53 is determined by the insertion of the support portion 53 and the supported portion 63 in the vertical direction. It is shorter than the length IL. Therefore, the stroller body 20 can efficiently support the weight of the seat 60 held by the holding member 50 at the first connection position JPX. Further, the distance D2 along the front-rear direction from the support portion 53 to the second connection position JPY located behind the support portion 53 is longer than the vertical insertion length IL of the support portion 53 and the supported portion 63. It is getting shorter. Therefore, at its second connection position JPY, baby carriage main body 20 can efficiently and stably receive inertial force from seat 60 during forward movement via holding member 50.

  As a result of the above mounting structure, the support portion 53 of the holding member 50 is located in a region surrounded by the first link member 21, the handle extension portion 42 of the handle 40, and the rear leg 35, as shown in FIG. . That is, the support portion 53 of the holding member 50 is generally located at the center of the stroller main body 20. Thus, the seat 60 can be stably and efficiently supported.

  By the way, as described above, the first connection position JPX of the holding member 50 to the stroller main body 20 is the main shaft member 25, and the second connection position JPY is the reinforcing connection member 45. Therefore, the holding member 50 is connected to the second link member 22, the third link member 23, and the handle extension 42 of the handle 40 via the main shaft member 25. The holding member 50 is connected to the handle extension 42 of the handle 40 via the reinforcing connection member 45. That is, the holding members 50 are connected to different positions on the handle extension 42 of the handle 40 via different paths. For this reason, the holding member 50 is fixed to the handle 40. Here, "fixed with respect to the handle 40" means not only that the handle is directly connected to the handle, but also that the handle is indirectly connected to the handle via another member and the relative position of the handle 40 to the handle. Is maintained constant.

  As described above, in the unfolded state shown in FIG. 2, the handle 40 is disposed at a high position. On the other hand, in the folded state shown in FIG. 3, the handle 40 is arranged at a lower position. By fixing the holding member 50 to such a handle 40, the seat 60 is arranged at a high position in the vertical direction in the deployed state. By arranging the seat 60 at a high position, the infant on the seat 60 can effectively avoid the influence of heat and dust from the ground. Further, since the seat surface 65A of the seat 60 is high, it is possible to easily and stably carry the infant on and off. On the other hand, in the folded state, as shown in FIG. 3, the handle 40 is located at a lower position. Along with the handle 40, the seat 60 is also arranged at a low position. Therefore, the folding size of baby carriage 10 can be reduced.

  Further, the direction of the holding member 50 is also constant with respect to the handle 40. Therefore, the seat 60 held by the holding member 50 does not generate a large moment during the folding operation. On the other hand, the weight of the seat 60 pushes down the handle 40. That is, the weight of the seat 60 assists the folding operation for lowering the handle 40. Therefore, the folding operation can be performed smoothly.

  In the illustrated example, the seat surface 65A formed by the seat 60 is located above the connection position JP1 between the first link member 21 and the front leg 30 in the side view shown in FIG. . Similarly, in the side view shown in FIG. 2, the swing axis AS <b> 1 of the back portion 70 with respect to the seat portion 65 is located above the connection position JP <b> 2 between the first link member 21 and the rear leg 35. In addition, in the side view shown in FIG. 2, the swing axis AS1 of the back portion 70 with respect to the seat portion 65 is located above the connection position JP4 between the handle 40 and the second link member 22. Further, in the side view shown in FIG. 2, the swing axis AS <b> 2 of the side frame member 73 with respect to the side support part 72 is located above the first link member 21. Further, the swing axis AS2 of the side frame member 73 with respect to the side support portion 72 is located above the connection position JP1 between the first link member 21 and the front leg 30, and the first link member 21 and the rear leg 35 Is located above the connection position JP2 of the first link member 21 and the handle 40. In the specific example illustrated in this manner, the seat 60 is held at a high position when the baby carriage 10 is deployed, so that it is possible to easily carry the baby in and out, recline, open and close the hood, and the like. On the other hand, since the seat 60 is fixed to the handle 40 as described above, the folding size of the baby carriage 10 can be sufficiently reduced.

  The stroller 10 having the above-described configuration travels when an operator (user or guardian) grips the handle connecting portion 43 of the handle 40 and presses the handle 40. In this baby carriage 10, as shown in FIG. 9, the direction of the seat 60 is changed, and the holding member 50 can hold the seat 60. That is, it is not necessary to swing the handle 40 when switching between the back state and the facing state. Therefore, the possibility that the handle 40 interferes with other components of the baby carriage 10 is reduced. For this reason, the reinforcing connecting member 45 for connecting the pair of handle extending portions 42, which has been considered impossible to install, can be installed on the handle main body 41.

  In the illustrated example, the handle 40 includes a pair of handle extensions 42 in addition to a handle body 41 having a pair of handle extensions 42 and a handle connecting portion 43 that connects ends of the pair of handle extensions 42. Further, a reinforcing connecting member 45 for connecting the portion 42 at a position separated from the handle connecting portion 43 is further provided. The handle connecting portion 43 effectively reinforces the handle main body 41, so that the rigidity of the handle 40 is improved. As a result, when a force is applied to the handle connecting portion 43 which is the upper end of the handle 40, the deformation of the handle 40 can be effectively suppressed. As a result, the force applied to the handle 40 is effectively used for running the baby carriage 10. Further, the operator can sufficiently grasp the state of the running surface and the like via the handle 40. From these, the maneuverability of the stroller 10 can be significantly improved.

  In addition, in the illustrated baby carriage 10, the member connected between both ends in the width direction of the reinforcing connecting member 45 extends at a position shifted from the connection position between the reinforcing connecting member 45 and the handle extending portion 42. It is connected to the section 42. More specifically, a member connected between both ends in the width direction of the reinforcing connection member 45 includes the holding member 50. As a result, the rigidity of the handle 40 can be further improved. In particular, the holding member 50 has a function of holding the seat 60, so that the rigidity of the handle 40 can be efficiently improved without increasing the number of components.

  This member connected between both ends in the width direction of the reinforcing connection member 45 is connected to the handle extension 42 on the rotation axis AR1 between the second link member 22 and the handle extension 42. . More specifically, the member connected between both ends in the width direction of the reinforcing connection member 45 further includes the main shaft member 25. In such a stroller 10, the rigidity of the handle can be further improved. In particular, the rigidity of the main shaft member 25 can be improved, whereby the folding operation and the unfolding operation can be smoothly performed.

  According to the embodiment described above, the seat 60 is a seat held by the stroller main body 20, and includes a pair of bases 61 having a supported portion 63 supported by the support portion 53 of the stroller main body 20. A seat 65 connected to the pair of bases 61, a back 70 connected to the pair of bases 61 and swingable with respect to the bases 61, and each base 61 being inclined upward and outward in the width direction. A pair of extended side support portions 72, side frame members 73 connected to the pair of side support portions 72 and swingable with respect to the side support portions 72, a back portion 70 and the side frame members 73; And a connecting frame member 74 that is rotatable with respect to the back portion 70 and the side frame member 73. In the seat 60, the pair of side support portions 72 to which the side frame members 73 are connected expand upward when viewed from the front. Therefore, the dimension W1 in the width direction of the region surrounded by the side frame member 73 can be made sufficiently large, whereby the space for the infant sitting on the seat 60 to move its limbs and upper body is expanded. That is, the livability of the baby carriage 10 is improved.

  Further, in the above-described specific example, the side support portion 72 includes an upper extension portion 72a that extends upward from the base 61 so as to be inclined outward in the width direction, and a rearward or rearward portion from the upper extension portion 72a. A rearward extending portion 72b extending upward and connected to the side frame member 73. In this case, it is easy to swingably connect the side frame member 73 to the side support portion 72 while tilting the side support portion 72 outward in the width direction.

  Further, in the above specific example, the width direction dimension W1 of the region surrounded by the side frame member 73 is larger than the width direction dimension W2 of the back part 70. In the seat 60, the side wall formed by the side frame member 73 and the back portion 70 is inclined outward from the back portion 70 in the width direction. This makes it easier for infants sitting on the seat 60 to move their limbs and upper body.

  In the above-described specific example, the stroller 10 includes the stroller main body 20 and the above-described seat 60 held by the stroller main body 20, and the stroller main body 20 includes a pair of strollers spaced apart in the width direction. The armrest 21 includes a support portion 53 that is arranged on the center side in the width direction with respect to the pair of armrests 21 and supports the seat 60. The side support portion 72 extends above the armrest 21. In this stroller 10, the pair of side support portions 72 can extend outward in the width direction from the inner side surfaces of the pair of armrests 21 facing each other. In this case, the livability of the baby carriage 10 is suppressed from being limited by the interval between the pair of armrests 21.

  Further, in the above specific example, the support portion 53 supports the seat 60 so as to be detachable. In this case, when the baby carriage 10 is designed, it is not necessary to consider the interference between the baby carriage body 20 and the side support portions 72 when the baby carriage main body 20 is folded. That is, the seat 60 may be removed from the stroller body 20 when the stroller body 20 is folded. Therefore, it can be more effectively suppressed that the livability of the stroller 10 is limited by the interval between the pair of armrests 21. In addition, the support part 53 can hold | maintain the seat 60 by changing the front-back direction.

  Although one embodiment has been described with a plurality of specific examples, these specific examples are not intended to limit the embodiment. The above-described embodiment can be carried out in various other specific examples, and various omissions, replacements, and changes can be made without departing from the gist of the embodiment.

  Hereinafter, an example of a modification will be described with reference to the drawings. In the following description and the drawings used in the following description, portions that can be configured in the same manner as in the above-described specific example will be denoted by the same reference numerals as those used for corresponding portions in the above-described specific example, and will be described in duplicate. Is omitted.

  For example, in the specific example described above, the example in which the holding member 50 is connected to the stroller main body 20 at the two connection positions JPX and JPY has been described. However, the present invention is not limited to this example. 20 may be connected.

  Further, in the specific example described above, an example is shown in which the support portion 53 of the holding member 50 is provided at a position shifted upward in the vertical direction from any one connection position of the stroller main body 20. It is not limited to the example. For example, the support portion 53 of the holding member 50 may be located between the two connection positions JPX and JPY.

  Further, the support portion 53 of the holding member 50 may be positioned on a provisional straight line connecting the two connection positions JPX and JPY. According to such a stroller 10, the stroller body 20 can efficiently receive the weight of the seat 60 held by the holding member 50. Thereby, the play of the holding member 50 with respect to the baby carriage main body 20 can be effectively prevented.

Further, the support portion 53 of the holding member 50 may be located between the two connection positions JPX and JPY in the front-rear direction. According to such a stroller 10, the stroller body 20 can efficiently receive the weight of the seat 60 held by the holding member 50.
