It should be noted that in this specification, the "front", "rear", "up", "down", "front-rear direction" and "relative to" the stroller 10 and the stroller body 20 without special instructions The term "up and down direction" refers to "front", "rear", "up", "down", "based on the operator (user, protector) of the stroller 10 in the deployed state. Front and back direction" and "up and down direction". Therefore, the “front-back direction” refers to the direction connecting the lower left and upper right of the paper surface in FIG. 1, and corresponds to the left-right direction of the paper surface in FIG. 2. In addition, as long as there is no special instruction, “front” refers to the side facing the operator who operates the stroller 10, and the lower left side of the paper in FIG. 1 and the left side of the paper in FIG. 2 are the front side of the stroller 10. On the other hand, "up and down direction" refers to a direction orthogonal to the front-rear direction and orthogonal to the landing surface. Therefore, when the ground surface is horizontal, "up and down direction" refers to the vertical direction. In addition, the "width direction" refers to the horizontal direction, and is a direction orthogonal to both the "front-rear direction" and the "vertical direction".

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. It should be noted that several constituent elements included in the stroller 10 are shown in some drawings, but the illustration is omitted in other drawings.

As described above, the stroller 10 includes the stroller body 20 and the seat 60 held by the holding member 50 provided on the stroller body 20. In addition, as indicated by the two-dot chain line in FIGS. 1 and 2, the stroller 10 has a seat cushion 80 detachably fixed to the seat 60. Infants and children ride on the cushion 80. In addition, the stroller 10 may further include constituent elements (not shown) such as a storage basket and a hood.

First, the stroller body 20 will be described with reference to the illustrated example. As shown in FIGS. 1 to 4, the stroller body 20 as a whole has a substantially symmetrical structure centered on the widthwise center plane along the front-rear direction. The stroller body 20 has wheels 33, 38 and a handle 40, and is a stroller that the operator can push forward by holding the handle 40. As shown in FIG. 4, the stroller body 20 has the first to third link members 21 to 23 in addition to the handle 40, the front leg 30 including the wheel 33 at the lower end, and the rear leg 35 including the wheel 38 at the lower end The main components. Since these constituent elements can perform the folding operation of the stroller body 20, the relative operation can be performed.

As shown in FIGS. 2 and 4, the first link member 21 is located above the front legs 30 and the rear legs 35 and extends in the front-rear direction. The pair of first link members 21 are provided so as to be separated in the width direction. The first link member 21 is formed as a resin molded product, for example.

As shown in FIGS. 2 and 4, a front leg 30 is connected to the first link member 21. Corresponding to the pair of first link members 21, the pair of front legs 30 are provided so as to be separated in the width direction. That is, each front leg 30 is connected to the first link member 21 on the corresponding side in the width direction. The front leg 30 is connected to the front part of the first link member 21, particularly the front end part of the first link member 21. The front leg 30 has a longitudinal direction. The front leg 30 is inclined with respect to the up-down direction and the front-back direction so that the longitudinal direction of the front leg 30 faces forward and downward. In the illustrated example, the front leg 30 is connected to the first link member 21 at its upper end. The front leg 30 is movably connected to the first link member 21. In other words, the first link member 21 and the front leg 30 can rotate around the axis along the width direction.

In the illustrated example, the front leg 30 includes a front leg main material 31 connected to the first link member 21 at one end thereof, a front wheel holding member 32 connected to the front leg main material 31, and an axle not shown The front wheel 33 held by the front wheel holding member 32. The front leg main material 31 has a longitudinal direction. The front leg main material 31 can be formed using a metal and/or resin pipe material, for example. The front wheel holding member 32 has a longitudinal direction and is formed as an extension of the front leg main material 31. The front wheel holding member 32 is connected to the lower end portion of the front leg main material 31. The front wheel holding member 32 is connected to the front leg main material 31 at its upper end portion.

As shown in FIG. 4, the front wheel holding member 32 holds an axle (not shown) to which the front wheels 33 are attached at the lower end portion. The front wheel holding member 32 has an attachment portion 32a attached to the front leg main material 31, an axle holding portion 32c that holds the front wheel 33 by the axle, and an intermediate support portion 32b therebetween. In the illustrated example, the intermediate support portion 32b is shifted inward in the width direction from the mounting portion 32a. As a result, the intermediate support portion 32b supports the axle holding portion 32c at a position shifted inward in the width direction from the front leg main material 31. The axle holding portion 32c may be rotatable with respect to the intermediate support portion 32b. At this time, the front wheel holding body including the front wheel 33 and the front wheel holding member 32 functions as a caster. In addition, in the illustrated example, the front wheel holding body has a pair of front wheels 33 on both sides of the axle holding portion 32c in the form of two wheels. Since the intermediate support portion 32b is shifted toward the inner side in the width direction relative to the mounting portion 32a, it is possible to avoid the front wheel 33 on the outer side in the width direction from protruding greatly in the width direction.

The front wheel holding member 32 is formed using a resin molded product, for example. In addition, the front wheel holding member 32 may include a metal pipe for reinforcement. For example, the intermediate support 32b may include a metal tube.

It should be noted that, in this specification, the inner side in the width direction refers to the side closer to the center of the stroller body 20 in the width direction. On the other hand, the outer side in the width direction refers to the side farther from the center of the stroller body 20 in the width direction.

As shown in FIGS. 4 and 5, the stroller body 20 has a member connecting a pair of front legs 30. In the illustrated stroller body 20, as shown in FIG. 5, the stroller body 20 has a front leg connecting member 26 connecting a pair of front legs 30 and a front member 27 provided on the front leg connecting member 26. The front leg connecting member 26 is formed using a metal pipe, for example. The front member 27 is formed using a resin molded product, for example.

Both ends of the front leg connecting member 26 are connected to the front wheel holding member 32. Therefore, in order to ensure the connection of the front leg connecting member 26 to the front leg 30, it is not necessary to provide another member on the front leg main material 31. In addition, in the side view shown in FIG. 2, the front leg connecting member 26 is blocked by the front wheel holding member 32. Therefore, it is also appropriate from a design point of view. In addition, the front member 27 is rotatable with respect to the front leg connecting member 26 about the rotation axis extending in the width direction. The front member 27 constitutes a part of the second link member 22 as described later.

As shown in FIGS. 2 and 4, a rear leg 35 is also connected to the first link member 21. Corresponding to the pair of first link members 21, the pair of rear legs 35 are provided so as to be separated in the width direction. That is, each rear leg 35 is connected to the first link member 21 on the corresponding side in the width direction. The rear leg 35 is connected to the front portion of the first link member 21, and particularly to the front end portion of the first link member 21. The rear leg 35 has a longitudinal direction. The rear leg 35 is inclined with respect to the up-down direction and the front-rear direction so that the longitudinal direction of the rear leg 35 faces rearward and downward. In the illustrated example, the rear leg 35 is connected to the first link member 21 at its upper end portion. The rear leg 35 is movably connected to the first link member 21. In other words, the first link member 21 and the rear leg 35 can rotate about the axis along the width direction.

In particular, as shown in FIG. 2, the rear leg 35 and the corresponding front leg 30 are connected to the first link member 21 at the same position. That is, the connection position JP1 of the first link member 21 and the front leg 30 and the connection position JP2 of the first link member 21 and the rear leg 35 coincide. Therefore, the rotation axis of the front leg 30 relative to the first link member 21 and the rotation axis of the rear leg 35 relative to the first link member 21 also coincide.

In the illustrated example, the rear leg 35 has a rear leg main material 36 connected to the first link member 21 at one end thereof, a rear wheel holding member 37 connected to the rear leg main material 36, and an axle not shown The rear wheel 38 held by the rear wheel holding member 37. The rear leg main material 36 is formed using a metal tube, for example. In the illustrated example, the rear leg main material 36 is bent or bent at its middle portion. In addition, the lower portion of the rear leg main material 36 is located closer to the inner side in the width direction than the upper portion of the rear leg main material 36. This can suppress the rear wheel holding member 37 and the rear wheels 38 from protruding outward in the width direction. The rear wheel holding member 37 is formed using a resin molded product, for example. The rear wheel holding member 37 may be provided with a braking mechanism of the rear wheels 38.

As shown in FIG. 4, the stroller body 20 has a rear leg connecting member 28 that connects a pair of rear legs 35. Both ends of the rear leg connecting member 28 are connected to the rear wheel holding member 37. Therefore, it is not necessary to provide a separate member on the rear leg main material 36 in order to ensure the connection of the rear leg connecting member 28 to the rear leg 35. In addition, in a side view, the rear leg connecting member 28 is blocked by the rear wheel holding member 37. Therefore, it is also appropriate from a design point of view. The rear leg connecting member 28 is formed using, for example, a resin molded product.

As shown in FIGS. 2 and 4, a handle 40 is also connected to the first link member 21. Hereinafter, the handle 40 will be described. As shown in FIG. 4, the handle 40 has a U-shaped handle body 41 and a reinforcement coupling member 45 that reinforces the handle body 41. The handle body 41 has a handle extension protrusion 42 arranged separately in the width direction, and a handle connection portion 43 connecting the handle extension protrusion 42. The pair of handle extension protrusions 42 are provided corresponding to the pair of first link members 21. The pair of handle extension protrusions 42 may have a symmetrical configuration. The handle extension protrusion 42 becomes a rod-shaped member having a longitudinal direction. The handle extension protrusion 42 is inclined with respect to the up-down direction and the front-back direction so as to face rearward and upward. Each handle extension protrusion 42 is connected to the corresponding first link member 21. Each handle extension protrusion 42 is connected to the rear portion of the first link member 21, particularly the rear end portion. The handle extension protrusion 42 is connected to the first link member 21 at its middle portion. The handle extension protrusion 42 is rotatable with respect to the first link member 21 about an axis extending in the width direction.

The handle coupling portion 43 connects the pair of handle extension protrusions 42 at the upper end portion of the pair of handle extension protrusions 42. The handle coupling portion 43 is a portion held by the operator of the stroller 10. The stroller body 20 has a fixing mechanism (not shown) for maintaining its expanded state. In addition, the handle coupling portion 43 is provided with an operating device 44 for remotely operating the fixing mechanism. The operator of the stroller 10 can start the folding operation of the stroller body 20 in the unfolded state by operating the operation device 44.

The handle body 41 is formed using a metal tube, for example. The handle extension protrusion 42 and the handle coupling portion 43 may be integrally formed.

The reinforcing connecting member 45 is formed using, for example, a resin molded product and/or a metal pipe. The reinforcing connecting member 45 connects the pair of handle extension protrusions 42 along the width direction. The reinforcement coupling member 45 is connected to the handle extension protrusion 42 at a position separated from the handle coupling portion 43. In particular, as shown in FIG. 2, the reinforcing connecting member 45 has a pair of handles near the end of the handle extension protrusion 42 on the side of the handle connection protrusion 43 that is not connected to the handle extension 43, that is, near the lower end of the handle extension protrusion 42. The extension protrusion 42 is connected. In other words, the reinforcement connecting member 45 is connected to the lower end portion of each handle extension protrusion 42 on the side separated from the handle connection portion 43 and the connection position JP3 of the handle extension protrusion 42 connected to the first link member 21. The handle extension protrusion 42 is connected.

Each protective support material 75 can rotate slightly around the base 61 about an axis extending in the width direction. In addition, the seat 60 has a pair of hood support materials 77 fixed by the respective side support portions 72. Although not shown in the figure, a hood frame is hung between a pair of hood support materials 77, and a hood cloth is attached to the hood frame.

It should be noted that in FIG. 8, illustrations of the seat plate 68, the protective material 76, the hood support material 77 and the like are omitted.

Next, the holding member 50 provided in the stroller body 20 and holding the seat 60 will be described. As shown in FIG. 6, a pair of holding members 50 is provided at a position between the pair of first link members 21 in the width direction. The pair of holding members 50 are arranged separately in the width direction. As shown in FIG. 1, the pair of holding members 50 hold the seat 60 in 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 may be formed as a receiving hole that opens upward, or as an insertion portion that protrudes upward. In addition, the supported portion 63 may be configured as a downwardly protruding insertion portion that can be inserted into the receiving hole of the supporting portion 53 or a downwardly opening receiving hole into which the insertion portion of the supporting portion 53 can be inserted. In the example of the drawings, the holding member 50 has a receiving hole formed in the supporting surface 52 facing upward as the supporting portion 53. The support surface 52 expands in the front-rear direction. In other words, a receiving hole as a supporting portion 53 is formed in the central portion of the supporting surface 52 that expands in the front-rear direction. The support surface 52 faces upward, and the receiving hole that becomes the support portion 53 opens upward.

On the other hand, the pair of base portions 61 of the seat 60 that are arranged apart in the width direction have a supported portion 63. That is, a pair of holding members 50 are provided so as to be separated in the width direction corresponding to each base 61. The base 61 has a supported surface 62 facing downward. The supported surface 62 and the supporting surface 52 are expanded in the front-rear direction. The insertion portion to be the supported portion 63 protrudes downward from the 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, by lowering the seat 60 from above in the vertical direction onto the stroller body 20, the seat 60 can be held to the front legs 30 via the holding member 50. More specifically, by lowering the seat 60, the supported portions 63 protruding downward from the pair of base portions 61 are inserted into the supporting portions 53 of the corresponding holding member 50. Then, by contacting the supported surface 62 of the base 61 with the support surface 52 of the holding member 50, the seat 60 is held on the stroller body 20. In a state where the seat 60 is held by the stroller body 20, the support portion 53 is engaged with the supported portion 63, so the seat 60 is restricted from moving relative to the stroller body 20 in the horizontal direction.

In addition, the pair of holding members 50 and the pair of bases 61 are arranged separately in the width direction. Therefore, in a state where the seat 60 is held by the stroller body 20, it is possible to effectively limit the deviation caused by the relative rotation of the seat 60 and the stroller body 20 centered on the axis along the front-rear direction, and The vertical axis is the center of the seat 60 and the stroller body 20 due to the relative rotation caused by the deviation. In addition, as shown in FIGS. 6 and 8, the support surface 52 expands forward and backward at the support portion 53, and the supported surface 62 expands back and forth before and after the supported portion 63. Therefore, even in a state where the seat 60 is held by the stroller body 20, it is possible to effectively limit the deviation caused by the relative rotation of the seat 60 and the stroller body 20 centered on the axis along the width direction. Thereby, the seat 60 can be stably held by the seat 60 provided in the stroller body 20.

It should be noted that, in the example shown in the figure, the stroller body 20 has a link structure for enabling a folding operation. These link structures include a pair of structures separated symmetrically about the center plane in the width direction in the width direction. In addition, the pair of holding members 50 are arranged between the pair of structures, and the seat 60 is held between the pair of structures. Specifically, the seat 60 is held between a pair of first link members 21, a pair of front legs 30, a pair of rear legs 35, and a pair of handle extension protrusions 42. Such an arrangement of the seat 60 can avoid interference with constituent elements of the stroller body 20. That is, the holding member 50 separates the seat 60 from the stroller body 20 and holds the seat 60. Therefore, as shown in FIG. 9, the orientation of the seat 60 held by the stroller body 20 via the holding member 50 can be changed. Thereby, only by changing the orientation of the seat 60, the infant and child shown in (a) of FIG. 9 can face the back of the stroller 10 in the traveling direction and the infant and child shown in (b) of FIG. The operator (protector) of the stroller 10 switches between the opposite states. In addition, such a configuration of the seat 60 can also avoid interference between the stroller body 20 and the seat 60 during the folding operation. Therefore, as shown in FIG. 3, the stroller body 20 can be folded with the seat 60 held. In the illustrated stroller 10, the stroller 10 can be folded in a state where the seat 60 is held by the stroller body 20 in any of the opposite state and the back state.

In addition, as shown in FIG. 8, the seat 60 has a protrusion 64 that receives a force from each supported portion 63 inward in the width direction. In addition, as shown in FIG. 6, in the holding member 50, a protrusion receiving portion 54 that receives the protrusion 64 is formed on the inner wall in the width direction of the walls forming the support portion (accommodation hole) 53. Since the lower side surface of the protrusion 64 is inclined, when the supported portion 63 is inserted into the support portion 53, it is automatically buried inside the supported portion 63. Then, when the protrusion 64 reaches a position opposite to the protrusion receiving portion 54, the protrusion 64 is fitted into the protrusion receiving portion 54 by an urging force from an unshown urging mechanism. 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 protrusion releasing mechanism 55 at a position opposite to the protrusion receiving portion 54. The protrusion releasing mechanism 55 protrudes inward in the width direction from the holding member 50. By pressing the protrusion releasing mechanism 55 outward in the width direction, the protrusion 64 embedded in the protrusion receiving portion 54 can be pushed out from the protrusion receiving portion 54. That is, when the seat 60 is detached from the stroller body 20, by operating the protrusion releasing mechanism 55, the fixing by the fixing mechanism composed of the protrusion 64 and the protrusion receiving portion 54 can be released.

Next, the attachment structure and attachment position of the holding member 50 to the stroller body 20 will be described.

In the present embodiment, as shown in FIG. 7, each holding member 50 is connected to a plurality of mutually separated connection positions JPX, JPY of the stroller body 20. As a result, in the illustrated example, each holding member 50 is fixed to the stroller body 20 and is stably held by the stroller body 20. In addition, the support portion 53 of the holding member 50 is located above one connection position JPX of the stroller 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. This can effectively reduce the looseness of the holding member 50 with respect to the stroller body 20. In addition, there is no need to enlarge the holding member 50 or provide a large number of holding members 50, so the design of the stroller 10 can also be improved.

In the illustrated example, first, each holding member 50 is connected to the handle extension protrusion 42 on the rotation axis AR1 of the second link member 22 and the handle extension protrusion 42. As a specific configuration, as shown in FIGS. 6 and 7, each holding member 50 is connected to a spindle member 25 that rotatably connects the second link member 22 and the handle extension protrusion 42. That is, in the illustrated example, the first connection position JPX of the holding member 50 with respect to the stroller body 20 is the spindle member 25. The spindle member 25 penetrates the holding member 50. The main shaft member 25 also 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 protrusion 42 of the handle 40 via the spindle member 25, but also to the second link member 22 and even the third link member 23.

In addition, each holding member 50 is connected to the reinforcing connection member 45 of the handle 40. The reinforcing coupling member 45 is connected to the handle extension protrusion 42 as a part of the handle 40. That is, in the illustrated example, the second connection position JPY of the holding member 50 with respect to the stroller body 20 is the reinforcement coupling member 45. As shown in FIG. 7, the holding member 50 has a through-hole 56 through which the reinforcing coupling member 45 passes. The cross-sectional shape of the reinforcing connecting member 45 is circular and slightly flat. The through hole 56 of the holding member 50 is also slightly flat. Therefore, by allowing the reinforcing coupling member 45 to penetrate the through-hole 56 of the holding member 50, the relative rotation of the holding member 50 relative to the stroller body 20 along the axis in the width direction is restricted.

In such a stroller 10, the first connection position JPX of the holding member 50 and the stroller body 20 is the main shaft member 25 and is connected to the lower portion of the holding member 50. Further, as shown in FIG. 7, the support portion 53 of the holding member 50 is arranged at a position offset upward from the main shaft member 25 in the vertical direction. Therefore, the weight of the seat 60 held by the holding member 50 can be effectively supported by the stroller body 20 without increasing the size of the holding member 50 or providing a large number of holding members 50.

In addition, the second connection position JPY of the holding member 50 and the stroller body 20 is the reinforcing coupling member 45 and is connected to the rear portion of the holding member 50. Therefore, as shown in FIG. 7, the holding member 50 faces the reinforcement coupling member 45 from the front in the front-rear direction. In addition, the support portion 53 of the holding member 50 is arranged at a position shifted forward from the reinforcement coupling member 45 in the front-rear direction. Therefore, the stroller body 20 can effectively and stably withstand the inertial force from the seat 60 when moving forward through the holding member 50. This can effectively suppress the occurrence of looseness of the holding member 50 relative to the stroller body 20.

In addition, if the distance between the two connection positions JPX and JPY of the stroller body 20 is close, the holding member 50 is easily loosened relative to the stroller body 20. On the other hand, if the insertion length IL of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60 in the vertical direction is long, it is possible to effectively suppress the seat 60 from loosening relative to the holding member 50. On the other hand, if the insertion length IL is long, a large force is applied to the holding member 50 and loosening of the holding member 50 relative to the stroller body 20 is likely to occur. In this regard, as shown in FIG. 7, the distance D between the two connection positions JPX and JPY is made longer than the insertion length IL in the vertical direction of the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60. This can further effectively suppress the occurrence of looseness of the holding member 50 with respect to the stroller body 20.

In addition, in order to use the stroller body 20 to effectively withstand the force applied to the holding member 50, it is effective to shorten the distances D1, D2 from the support portion 53 of the holding member 50 toward the stroller body 20 to the connection positions JPX, JPY . 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 preferably greater than the length of the support portion 53 and the supported portion 63 The vertical insertion length IL is short. In the illustrated example, the shortest distance from the support portion 53 of the holding member 50 to any of the connection positions JPX, JPY is shorter than the insertion length IL of the support portion 53 and the supported portion 63 in the vertical direction. 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 support portion 53 is connected to the second The shortest distance D2 between the positions JPY is shorter than the insertion length IL of the support portion 53 and the supported portion 63 in the vertical direction.

In particular, in the illustrated example, the distance D1 in the vertical direction from the support portion 53 to the first connection position JPX located below the support portion 53 is greater than the vertical insertion length of the support portion 53 and the supported portion 63 IL is short. Therefore, the stroller body 20 can effectively support the weight of the seat 60 held by the holding member 50 at the first connection position JPX. In addition, the distance D2 in the front-rear direction from the support portion 53 to the second connection position JPY located behind the support portion 53 is shorter than the insertion length IL in the vertical direction of the support portion 53 and the supported portion 63. Therefore, the stroller body 20 can effectively and stably receive the inertial force from the seat 60 at the time of forward movement through the holding member 50 at the second connection position JPY.

As a result of the above mounting structure, as shown in FIG. 2, the support portion 53 of the holding member 50 is located in the area surrounded by the first link member 21, the handle extension protrusion 42 of the handle 40 and the rear leg 35. That is, the support portion 53 of the holding member 50 is located approximately in the center of the stroller body 20. Thereby, the seat 60 can be supported stably and efficiently.

However, as described above, the first connection position JPX of the holding member 50 and the stroller body 20 is the main shaft member 25, and the second connection position JPY is the reinforcement coupling member 45. Therefore, the holding member 50 is connected to the second link member 22, the third link member 23, and the handle extension protrusion 42 of the handle 40 via the spindle member 25. In addition, the holding member 50 is connected to the handle extension protrusion 42 of the handle 40 via the reinforcement coupling member 45. In other words, the holding member 50 is connected to mutually different positions on the handle extension protrusion 42 of the handle 40 via mutually different paths. Therefore, the holding member 50 is fixed with respect to the handle 40. Here, "fixed with respect to the handle 40" not only means directly connected to the handle, but also includes indirectly connected to the handle through other components and constantly maintains the relative position with the handle 40.

As described above, in the expanded state shown in FIG. 2, the handle 40 is arranged at a high position. On the other hand, in the folded state shown in FIG. 3, the handle 40 is arranged at a low position. By fixing the holding member 50 with respect to such a handle 40, the seat 60 is arranged at a high position in the vertical direction in the expanded state. By arranging the seat 60 at a high position, it is possible to effectively prevent infants on the seat 60 from being affected by heat and dust from the ground. In addition, since the seat surface 65A of the seat 60 is high, it is possible to easily and stably carry on and off the infant. On the other hand, in the folded state, as shown in FIG. 3, the handle 40 is arranged at a low position. Along with the handle 40, the seat 60 is also arranged in a low position. Therefore, the folding size of the stroller 10 can be reduced.

In addition, the orientation of the holding member 50 is also constant with respect to the handle 40. Therefore, during the folding operation, the seat 60 held by the holding member 50 does not generate a large torque. On the other hand, the weight of the seat 60 presses the handle 40. That is, the weight of the seat 60 assists the folding operation of lowering the handle 40. Therefore, the folding operation can be smoothly performed.

In the illustrated example, in the side view shown in FIG. 2, the seat surface 65A formed by the seat 60 is located above the connection position JP1 of the first link member 21 and the front leg 30. . Similarly, in the side view shown in FIG. 2, the back portion 70 is positioned above the connection position JP2 of the first link member 21 and the rear leg 35 with respect to the swing axis AS1 of the seat 65. In addition, in the side view shown in FIG. 2, the back portion 70 is located above the connecting position JP4 of the handle 40 and the second link member 22 relative to the swing axis AS1 of the seat 65. In the side view shown in FIG. 2, the side frame member 73 is located above the first link member 21 with respect to the swing axis AS2 of the side support 72. In addition, the side frame member 73 is located above the connection position JP1 of the first link member 21 and the front leg 30 with respect to the swing axis AS2 of the side support portion 72, and is located more than the first link member 21 and The connection position JP2 of the rear leg 35 is closer to the upper position, and is located higher than the connection position JP3 of the first link member 21 and the handle 40. In this way, in the specific example shown in the drawing, since the seat 60 is held at a high position in the unfolded state of the stroller 10, it is possible to easily carry on and off the infant, adjust the seatback, and open and close the hood, etc. . On the other hand, as described above, since the seat 60 is fixed to the handle 40, the folding size of the stroller 10 can be sufficiently reduced.

The stroller 10 including the above-described structure travels by the operator (user, protector) holding the handle coupling portion 43 of the handle 40 and pressing the handle 40. In this stroller 10, as shown in FIG. 9, by changing the orientation of the seat 60, the holding member 50 can hold the seat 60. That is, when switching between the back state and the opposite state, the handle 40 does not need to be actuated. Therefore, the possibility that the handle 40 interferes with other constituent elements of the stroller 10 is low. Therefore, it is also possible to provide the reinforcing body connecting member 45 which connects the pair of handle extension protrusions 42 that was previously considered impossible to be provided to the handle body 41. In the illustrated example, the handle 40 has a handle body 41 including a pair of handle extension protrusions 42 and a handle coupling portion 43 connecting the ends of the pair of handle extension protrusions 42 and a pair of handles The extension protrusion 42 is a reinforcement coupling member 45 coupled at a position separated from the handle coupling portion 43. The handle coupling portion 43 effectively reinforces the handle body 41 to improve the rigidity of the handle 40. As a result, when a force is applied to the handle coupling portion 43 which is the upper end portion 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 when the stroller 10 is traveling. In addition, the operator can fully grasp the state of the traveling surface and the like through the handle 40. Thus, the handleability of the stroller 10 can be significantly improved.

In addition, in the illustrated stroller 10, the member connected between both ends in the width direction of the reinforcing link member 45 is shifted from the handle at a position offset from the connection position of the reinforcing link member 45 and the handle extension protrusion 42 The extension protrusion 42 is connected. More specifically, the member connected between both ends in the width direction of the reinforcing coupling member 45 includes the holding member 50. As a result, the rigidity of the handle 40 can be further improved. In particular, since the holding member 50 has a function of holding the seat 60, it is possible to effectively increase the rigidity of the handle 40 without increasing the number of parts.

In addition, the member connected between the both ends in the width direction of the reinforcing connecting member 45 is connected to the handle extension protrusion 42 on the rotation axis AR1 of the second link member 22 and the handle extension protrusion 42. More specifically, the member connected between both ends in the width direction of the reinforcing coupling 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 increased, so that the folding operation and the unfolding operation can be smoothly performed.

According to one embodiment described above, the stroller 10 has a foldable stroller body 20 and a seat 60 held by the stroller body by the holding member 50 provided on the stroller body. The stroller body includes a first link member 21, a front leg 30 and a rear leg 35 rotatably connected to the first link member, a handle 40 rotatably connected to the first link member, and a handle provided on the front leg and the handle The second link member 22 that can rotate relative to the front leg and the handle. The holding member 50 is fixed with respect to the handle. In such a stroller 10, when the stroller body 20 is folded, the handle 40 approaches the front leg 30, and the handle 40 is lowered. Thereby, the folding size of the stroller 10 in the front-rear direction and the vertical direction can be reduced. In addition, in the stroller 10, the holding member 50 that supports the seat 60 is fixed to the handle 40. Therefore, the seat 60 also descends when the stroller body 20 is folded. Thereby, the folding size of the stroller 10 can also be effectively reduced. In addition, compared with the first link member 21 and the second link member 22, the direction of the handle 40 changes less with the folding operation. Therefore, the orientation change of the seat 60 during folding is also suppressed, and the stroller 10 can be stably folded. In addition, the folding motion of the stroller 10 as the handle 40 is lowered can be guided by the weight of the seat 60. As described above, according to the present embodiment, the folding size of the stroller 10 can be sufficiently miniaturized. In addition, the folding operation of the stroller 10 can be performed smoothly and stably.

In one specific example described above, the holding member 50 holds the seat 60 so that the seat 60 is separated from the stroller body 20. In such a stroller 10, if the seat 60 does not interfere with components other than the handle 40 of the stroller body 20, the stroller 10 can be folded without removing the seat 60 from the stroller body 20.

In one specific example described above, the stroller body 20 can hold the seat 60 in a detachable manner, and can hold the seat 60 while changing the front-rear direction. That is, in the stroller 10, it is possible to ride the infant (in the opposite state) and toward the movement direction of the stroller so as to face the operator of the stroller 10 (the protector of the infant, the user of the stroller) Infant and infant ride forward (back state) on both sides. In addition, if the seat 60 does not interfere with constituent elements other than the handle 40 of the stroller body 20, the stroller 10 can be folded with the seat 60 attached to the stroller body 20 without depending on the orientation of the seat 60.

In a specific example described above, the holding member 50 is connected to the handle 40 at two or more positions. Thereby, the holding member 50 can be fixed to the handle 40 with a simple structure.

In a specific example described above, the handle 40 has: a handle body 41 having a pair of handle extension protrusions 42 and a handle coupling portion 43 connecting the pair of handle extension protrusions 42; and a pair of handle extension protrusions 42 in The reinforcement coupling member 45 coupled at a position separated from the handle coupling portion 43, and the holding member 50 are connected to the reinforcement coupling member 45. In such a stroller 10, the rigidity of the handle 40 is improved by reinforcing the connecting member 45. In addition, by connecting the holding member 50 to the reinforced connection portion 45, the seat 60 can be stably held by the stroller body 20.

In one specific example described above, the holding member 50 is connected to the handle extension protrusion 42 on the rotation axis AR1 of the second link member 22 and the handle extension protrusion 42. The positions of the rotation axis AR1 of the second link member 22 and the handle 40 are lowered when the stroller body 20 is folded. With this lowering, the second link member 22 and the handle 40 rotate about the rotation axis AR1. On the other hand, in this stroller 10, the weight of the seat 60 held by the holding member 50 can be applied to the rotation axis AR1 of the second link member 22 and the handle extension protrusion 42. Therefore, the weight of the seat 60 can smoothly guide the folding operation of the stroller body 20.

In one specific example described above, the holding member 50 is connected to the handle extension protrusion 42 via the spindle member 25 that rotatably connects the second link member 22 and the handle extension protrusion 42. The position of the main shaft member 25 is lowered during the folding operation of the stroller body 20, and the second link member 22 and the handle 40 relatively rotate with the lowering. In addition, when the weight of the seat 60 held by the holding member 50 is applied to the main shaft member 25, the folding operation of the stroller body 20 can be smoothly guided.

In a specific example described above, the stroller body 20 further includes a pair of third link members 23 provided between each rear leg 35 and the handle 40 and rotatable relative to the corresponding rear leg 35 and handle 40. The third The link member 23 is rotatably connected to the handle extension protrusion 42 and the second link member 22 in the AR1 through the spindle member 25. In such a stroller 10, the weight of the seat 60 held by the holding member 50 is applied to the main shaft member 25, thereby also guiding the folding of the third link member 23 and the rear leg 35 connected to the third link member 23 Time action. Therefore, the folding operation of the stroller body 20 can be further smoothly guided.

In one specific example described above, a pair of holding members 50 are provided separately between the both ends of the reinforcing connecting member 45 in the width direction. In the stroller 10, the seat 60 can be held by the pair of holding members 50 separated in the width direction. Thus, the stroller body 20 can hold the seat 60 more stably. In addition, the seat 60 can also be held inside the both ends of the reinforcing connection member 45. At this time, by not interfering with the constituent elements of the stroller body 20, the stroller 10 can be folded with the seat 60 attached to the stroller body 20.

In a specific example described above, in the side view of the stroller 10, the holding member 50 is located in an area surrounded by the first link member 21, the handle 40, and the rear leg 35. That is, in a side view, the stroller body 20 can bear the weight of the seat 60 held by the holding member 50 in the area surrounded by the first link member 21, the handle 40 and the rear leg 35. In this way, the stroller body 20 receives the seat 60 in the region with high rigidity, so that the seat 60 can be stably held to improve the maneuverability of the stroller 10.

In the above specific example, in the side view of the stroller 10, the seat surface 65A formed by the seat 60 is located above the connection position JP1 of the first link member 21 and the front leg 30. In addition, the seat 60 has a seat 65 and a back 70 that can be slid with respect to the seat 65. In a side view of the stroller 10, the back 70 is located with respect to the swing axis AS1 of the seat 65 than the first link member The connecting position JP2 of 21 and the rear leg 35 is close to the upper position. In addition, the seat 60 has a seat 65 and a back 70 that can be slid with respect to the seat 65. In a side view of the stroller 10, the back 70 is located relative to the swing axis AS1 of the seat 65 than the handle 40 and the second The connecting position JP4 of the link member 22 is close to the upper position. In this way, by raising the height of the seat 60, the riding comfort of the stroller 10 can be improved, and the infant can be easily boarded and seated on the seat 60. It should be noted that when the stroller 10 is folded, the seat 60 and the handle 40 are lowered together. Therefore, even if the position of the seat surface 65A is raised, the folding size of the stroller 10 can be sufficiently reduced.

In a specific example described above, the seat 60 has a seat 65, a back 70 that can be moved relative to the seat 65, and a position that is located above the back 70 and can be moved relative to the back 70 In the side view of the stroller 10, the side frame 73 that is moved by the seat 65 is located at a position where the first frame member 21 is connected to the handle 40 with respect to the axis of rotation AS2 of the seat 65. JP3 is near the top. In addition, the seat 60 has a seat 65, a back 70 that can be moved relative to the seat 65, and a seat that is located above the back 70 and that can be moved relative to the seat 65 as the back 70 moves. In the side view of the stroller 10, the side frame 73 is located above the first link member 21 with respect to the swing axis AS2 of the seat 65. In this way, by raising the height of the side frame 73, the side frame 73 can effectively protect the infant. In addition, the side frame material 73 can be easily operated. It should be noted that when the stroller 10 is folded, the seat 60 and the handle 40 are lowered together.
