Description

[Technical Field]

[0001] The present invention relates to a stroller with a basket. [Background technology]

[0002] Strollers used for taking babies and young children are widely used. As disclosed in JP2018-202982A, it is known that the seats of strollers have a seat and a back, and can be reclined by changing the inclination angle of the back relative to the seat.

[0003] Some strollers are equipped with a basket for storing luggage. The basket is attached to the front or rear legs that support the seat below the seat. This allows the space below the seat to be used effectively.

[0004] If the stroller tilts backward while being operated, luggage stored in the basket may fall out. If the rear wall of the basket is made higher to prevent this, it may interfere with the reclining function. In other words, the rear wall of the basket may interfere with the back of the seat, making it impossible to tilt the back as desired. DISCLOSURE OF THE INVENTION

[0005] The present invention has been made in consideration of the above points, and aims to reduce the risk of luggage stored in the basket falling out without interfering with the reclining function.

[0006] The stroller according to this embodiment is a stroller body including front and rear legs; A basket attached to the stroller body, Equipped with the stroller body includes a body frame including the front legs and the rear legs, and a seat support unit supported by the body frame and having a seat support and a back support, The back support is swingable relative to the main body frame, the car includes a bottom wall portion located below the seat support and a rear wall portion connected to a rear edge of the bottom wall portion; The rear wall is attached to the back support.

[0007] According to the present invention, the risk of luggage stored in the car falling out can be reduced without interfering with the reclining function. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present invention will now be described with reference to a specific example shown in the drawings.

[0010] Figures 1 to 11 are diagrams for explaining an embodiment of a stroller according to the present invention. Of these, Figures 1 to 4 show the overall structure of one specific example of the stroller. Figures 5 and 6 are perspective views showing parts of the stroller.

[0011] The stroller 10 of this embodiment has a main body frame 12, a seat support unit 50 having a back support 51 that can swing relative to the main body frame 12, and a reclining member 56 that is connected to the main body frame 12 and supports the back support 51 from the rear side. As shown in FIG. 1, the stroller 10 also has a basket 80. The basket 80 is attached below the seat support unit 50, which will be described later. This allows the space below the seat support unit 50 to be effectively used as space for storing luggage.

[0012] A stroller 10 shown in Figs. 1 to 4, which is one specific example of this embodiment, has a foldable stroller body 11. The stroller body 11 has a body frame 12 and a seat support unit 50 supported by the body frame 12. The body frame 12 has front legs 14 and rear legs 16, and a handle 40 that can swing back and forth. Front wheels 18 and rear wheels 19 are rotatably provided at the lower ends of the front legs 14 and rear legs 16, respectively. The front wheels 18 and rear wheels 19 are held by front wheel holding members 18a and rear wheel holding members 19a connected to the lower ends of the front wheels 18 and rear wheels 19, respectively. The front wheel holding members 18a and front wheels 18 form casters that are rotatable around rotation axes 18b extending horizontally and swivel around pivot axes extending vertically. The rear wheel holding member 19a and the rear wheel 19 also form a caster, and are rotatable around a rotation axis 19b extending in the horizontal direction, and are also rotatable around a swivel axis extending in the vertical direction.

[0013] In the illustrated example, the handle 40 can swing between a first position and a second position. In the illustrated example, the first position of the handle 40 is a rear-pushing position (see FIGS. 1 and 2), and the second position of the handle 40 is a forward-pushing position (see FIGS. 3A and 3B). As shown in FIG. 2, the handle 40 is inclined relative to the vertical and extends rearward at the first position, which is the rear-pushing position. When the handle 40 is placed in the first position, which is the rear-pushing position, the operator (guardian) grips the handle 40 from behind the baby to steer the stroller 10. At this time, the baby can face forward in the direction of travel and enjoy the scenery while the stroller 10 is traveling. As shown in FIGS. 3A and 3B, the handle 40 is inclined relative to the vertical and extends forward at the second position, which is the forward-pushing position. When the handle 40 is located in the second position, which is the facing-pushing position, the operator grips the handle 40 from the position on the side of the front legs 14 facing the baby to steer the stroller 10. At this time, the stroller 10 can be driven with the rear legs 16 of the stroller 10 facing forward in the direction of travel.

[0014] In this specification, the terms "front," "rear," "up," "down," "front-to-back direction," and "vertical direction" used with respect to a stroller and its components refer to the "front," "rear," "up," "down," "front-to-back direction," and "vertical direction" relative to an infant riding in the stroller and its components in an unfolded state, unless otherwise specified. More specifically, the "front-to-back direction" refers to the direction connecting the lower left and upper right of the page in FIG. 1, which corresponds to the left-to-right direction of the page in FIG. 2. Unless otherwise specified, "front" refers to the side facing the infant riding in the stroller, with the lower left of the page in FIG. 1 and the left of the page in FIG. 2 being the front side. Meanwhile, the "vertical direction" refers to the direction perpendicular to the running surface of the stroller. Therefore, when the running surface is horizontal, the "vertical direction" refers to the vertical direction. Furthermore, the "lateral direction" refers to the width direction, which is the direction perpendicular to both the "front-to-back direction" and the "vertical direction." Furthermore, the "rear side" used in connection with the back support 51, etc., means the side opposite to the side facing the baby riding in the stroller 10. Therefore, the "rear side" usually means the rear side or the lower side.

[0015] First, the stroller body 11 will be described as part of the overall configuration of the stroller 10. As shown in FIG. 1, the stroller body 11 is generally symmetrical about a plane that is located at the center in the lateral direction and that is aligned in the front-rear and up-down directions. As shown in FIG. 1, the stroller body 11 has a pair of front legs 14 arranged on the left and right, and a pair of rear legs 16 arranged on the left and right. The main body frame 12 further has a first link L1, a second link L2, a third link L3, and a fourth link L4 arranged on the left and right, respectively. The front legs 14, the rear legs 16, and the first to fourth links L1 to L4 function as links that make the stroller body 11 foldable and unfoldable. In the illustrated example, the first link L1 also functions as an armrest 21. That is, the armrest 21 constitutes the first link L1.

[0016] As shown in FIG. 2, the upper end portion of the front leg 14 is rotatably (swingably) connected to the front portion of the first link L1 located on the corresponding side (left or right). The upper end portion of the rear leg 16 is rotatably (swingably) connected to the front portion of the first link L1 located on the corresponding side (left or right). Also, as shown in FIGS. 3A and 3B, the upper portion of the second link L2 is rotatably (swingably) connected to the rear portion of the first link L1 located on the corresponding side (left or right). As shown in FIG. 5, in the illustrated example, the second link L2 has a main link member 22 and an upper connecting member 23 fixed to the upper end of the main link member 22. The main link member 22 is made of, for example, a metal pipe. The upper connecting member 23 is made of, for example, a resin molded part. The second link L2 is rotatably (swingably) connected to the rear end portion of the armrest 21 at the upper connecting member 23.

[0017] As shown in FIGS. 1 to 3B, the third link L3 is rotatably (swingably) connected to the front leg 14. The fourth link L4 is rotatably (swingably) connected to the rear leg 16. The third link L3 is rotatably (swingably) connected to at least one of the second link L2 and the fourth link L4. The fourth link L4 is rotatably (swingably) connected to at least one of the second link L2 and the third link L3. The second link L2 is rotatably (swingably) connected to at least one of the third link L3 and the fourth link L4.

[0018] As shown in FIGS. 1 and 5 , in the illustrated example, the third link L3 includes a frame member 24 and a front connecting member 25 and a rear connecting member 26 fixed to the frame member 24. The frame member 24 is made of, for example, a bent metal pipe. The front connecting member 25 and the rear connecting member 26 are made of, for example, a resin molded product. The frame member 24 is U-shaped and has a pair of side portions 24a extending in the front-to-rear direction and a connecting portion 24b connecting the pair of side portions 24a at the front. One end of the front connecting member 25 is rotatably connected to the front leg 14, and the other end is fixed to the front portion of the side portion 24a. The rear connecting member 26 is fixed to the rear end portion of the side portion 24a. In this example, the right-side third link L3 is formed by the side portion 24a of the frame member 24 located on the right side and the right-side front connecting member 25 and rear connecting member 26 fixed to the right side portion 24a. Similarly, the left third link L3 is formed by the side portion 24a of the frame material 24 located on the left side and the left front connecting member 25 and rear connecting member 26 fixed to this left side portion 24a.

[0019] As shown in FIG. 5 , in the illustrated example, the fourth link L4 has a main shaft member 28 rotatably connected to the rear leg 16 and an end member 29 fixed to the upper end portion of the main shaft member 28. The main shaft member 28 is made of, for example, a metal pipe. The end member 29 is made of, for example, a resin molded part. The main shaft member 28 is rotatably connected at its lower end portion to the middle portion of the rear leg 16. The end member 29 is rotatably connected to the second link L2 and the third link L3. In the illustrated example, the second link L2, the third link L3, and the fourth link L4 are rotatably connected to one another using the same shaft member 30. This shaft member 30 passes through the main link member 22 of the second link L2, the end member 29 of the fourth link L4, and the rear connecting member 26 forming the third link L3. With this configuration, the second link L2, the third link L3, and the fourth link L4 are rotatable relative to one another around an axis that coincides with the central axis of the shaft member 30.

[0020] The stroller body 11 further has a swingable handle 40. In the example shown, the handle 40 has a handle body 41 swingably attached to other components of the stroller body 11, and a holder 42 provided on the handle body 41. In the stroller body 11 shown, the handle 40 can swing between a first position (backward pushing position) inclined rearward from the vertical axis in a side view, and a second position (face-to-face pushing position) inclined forward from the vertical axis.

[0021] As shown in FIG. 1, the handle body 41 includes a pair of handle extensions 41a extending substantially parallel to each other and an intermediate portion 41b connecting the pair of handle extensions 41a. The handle body 41 has a substantially U-shape overall. The handle 40 is rotatably (swingably) connected to other components of the stroller body 11 at both ends of the U. In the illustrated example, the handle body 41 is rotatably connected to the other components using a shaft member 30. That is, the second link L2, the third link L3, the fourth link L4, the handle 40, and a back frame member 31 (described later) are rotatable relative to each other around the same axis defined by the shaft member 30. A holder 42 provided on the handle 40 engages with a first position retaining member 36 (see FIGS. 3A and 3B) of the main body frame 12, thereby maintaining the handle 40 in the first position shown in FIG. 2. A retaining member 42 provided on the handle 40 engages with a second position retaining member 37 (see Figure 2) of the main body frame 12, thereby maintaining the handle 40 in the second position shown in Figures 3A and 3B.

[0022] As shown in FIG. 1, the stroller body 11 has, as laterally extending components, a front connecting member 15 that connects the pair of front legs 14 and a rear connecting member 17 that connects the pair of rear legs 16. The front connecting member 15 functions as a footrest. A central connecting member 27 is provided between the pair of rear connecting members 26. The front connecting member 15, rear connecting member 17 and central connecting member 27 can suppress lateral deformation of the stroller 10. Furthermore, a flexible guard member 38 is removably provided between the pair of first links L1.

[0023] The stroller body 11 configured as described above can be folded by rotating each component relative to the other. Specifically, the handle 40, which is positioned in the first position, is first pulled up and rearward, and then pushed downward, causing the fourth link L4 to rotate clockwise in FIG. 2 relative to the rear legs 16. This operation causes the first link L1 and the third link L3 to rotate clockwise in FIG. 2 relative to the second link L2. This operation causes the handle 40 and the front legs 14 to move closer to each other while maintaining a substantially parallel arrangement in a side view, and also causes the handle 40 to be lowered. In this manner, the stroller body 11 can be folded as shown in FIG. 4. In the folded state shown in FIG. 4, the dimensions of the stroller 10 in the front-to-rear and up-to-down directions can be reduced. On the other hand, the stroller body 11 can be unfolded from the folded state by following the steps of the folding operation described above in reverse.

[0024] The stroller body 11 has a state maintaining mechanism (not shown) that restricts the relative rotation of the two components. By operating this state maintaining mechanism, the stroller body 11 can be folded. In the example shown, the handle 40 has a remote control device 43 connected to the state maintaining mechanism. As shown in FIG. 1, the remote control device 43 is provided on the middle part 41b of the handle body 41. By operating the remote control device 43, the state maintaining mechanism is activated, and the stroller body 11 can be folded.

[0025] As shown in FIGS. 1 to 3B, the illustrated stroller body 11 further includes a back frame member 31, an upper frame member 32, and a connecting frame member 33 that connects the back frame member 31 and the upper frame member 32. The back frame member 31 and the upper frame member 32 are both U-shaped. As shown in FIG. 1, a base cloth member 34 is held in a tensioned state by the frame member 24 and the back frame member 31. As shown in FIG. 6, the base cloth member 34 is attached to a pair of side portions 24a and a connecting portion 24b of the frame member 24. As shown in FIGS. 6 and 7, the back frame member 31 includes a pair of side frame portions 31a and a connecting frame portion 31b that connects the ends of the pair of side frame portions 31a. The base cloth member 34 is attached to the pair of side frame portions 31a and the connecting frame portion 31b.

[0026] The base cloth material 34, together with the frame material 24, the back frame material 31, the upper frame material 32, and the connecting frame material 33, supports a cushioned seat material 70, shown by the two-dot chain line in Figure 2. In the illustrated example, of the components included in the stroller body 11, the frame material 24, the back frame material 31, the upper frame material 32, the connecting frame material 33, and the base cloth material 34 form a seat support unit 50 that supports the seat material 70. The other components included in the stroller body 11 form the main body frame 12. Of the components that make up the seat support unit 50, the back frame material 31 and the region 34a held by the back frame material 31 of the base cloth material 34 form a back support body 51 that supports the back of the infant. Furthermore, the region 34b held by the frame material 24 and the frame material 24 of the base cloth material 34 form a seat support body 52 that supports the infant's buttocks. Hereinafter, the region 34a of the base fabric material 34 held by the back frame member 31 will also be referred to as the "back region 34a." Additionally, the region 34b of the base fabric material 34 held by the frame members 24 will also be referred to as the "seat region 34b." Note that the back frame member 31, the upper frame member 32, and the connecting frame member 33 are not shown in Figure 4.

[0027] As shown in FIG. 5 , the back frame member 31 is penetrated by the pivot members 30 at both ends thereof, specifically at the base ends of a pair of side frame members 31 a in the illustrated example. That is, the base end of the back support member 51 is connected to the rear end of the seat support member 52 via the pivot members 30. The back frame member 31 is rotatable (swingable) relative to the frame member 24 and other components. That is, the back support member 51 is rotatably (swingably) connected to the seat support member 52 via the pivot members 30. The swinging of the back support member 51 relative to the seat support member 52 enables the seat support unit 50 (and therefore the seat member 70) to recline. In the positions shown in FIGS. 3A , 5 , and 6 , the back support member 51 is inclined and reclined, allowing an infant to lie on the seat member 70. In the position shown in FIG. 3B , the back support member 51 is in an upright position, allowing an infant to sit on the seat member 70.

[0028] The upper frame member 32 is rotatably (swingably) connected at both ends to the rear end portion of the first link L1. The rotation axis of the upper frame member 32 relative to the first link L1 is aligned with the rotation axis of the second link L2 relative to the first link L1. A pair of connecting frame members 33 are provided between the back frame member 31 and the upper frame member 32, spaced apart in the lateral direction. The connecting frame members 33 are rotatably connected to the back frame member 31 and the upper frame member 32 at both ends.

[0029] The connecting frame member 33 is connected to the tip end of the back frame member 31, i.e., the connecting frame member 31b. When the back support member 51 is lying down together with the seat support member 52 as shown in Fig. 3A, the connecting frame member 33 stands up relative to the back frame member 31 that forms the back support member 51. The connecting frame member 33 covers and protects the baby's head from behind. On the other hand, when the back support member 51 is in an upright position as shown in Fig. 3B, the connecting frame member 33 extends upward from the tip end of the back frame member 31 and functions as a headrest.

[0030] 3A and 3B, the stroller body 11 further has a reclining mechanism 55. The reclining mechanism 55 maintains the back support 51 at a predetermined inclined position relative to the seat support 52 by restricting the tilting of the back support 51 toward the rear side. In the example shown, the reclining mechanism 55 has a reclining member 56 connected to the main body frame 12. The reclining member 56 is connected to the main body frame 12 and is positioned on the rear side of the back support 51, thereby supporting the back support 51 from the rear side.

[0031] The reclining member 56 shown in the figure is configured as a long, thin string-like or belt-like member. One end of the reclining member 56 is connected to the main frame 12, and the other end is fixed to the back support 51, thereby restricting the free tilting of the back support 51 toward the rear side. In the example shown in the figure, the reclining members 56 are configured as a pair of left and right string-like or belt-like members. One end of each reclining member 56 is connected to the rear portion of the corresponding first link L1, particularly to the connection position between the first link L1 and the second link L2.

[0032] The illustrated reclining mechanism 55 further includes a fastener 57 that fastens the reclining members 56 to the back support 51. In the illustrated example, the fastener 57 fastens the pair of reclining members 56 to each other on the rear side of the back support 51. As a result, the back support 51 is disposed between the pair of reclining members 56 and is restricted from further rocking rearward. The illustrated fastener 57 can releasably hold the pair of reclining members 56. More specifically, the fastener 57 is formed with a through-hole through which each reclining member 56 movably passes. The fastener 57 is detachable and attachable to any position along the longitudinal direction of each reclining member 56.

[0033] FIG. 7 is a plan view showing the back support 51 and the reclining mechanism 55 removed from the stroller body 11 and the seat support unit 50. FIG. 7 shows the rear side of the back support 51. As shown in FIG. 7, a cover member 35 is provided on the rear side of the base cloth material 34. The cover member 35 extends elongatedly in the horizontal direction. End openings 35a are formed between the cover member 35 and the base cloth material 34 at both ends. A reclining member 56 on the corresponding side is inserted through each end opening 35a. The cover member 35 has a central opening 35b formed in its horizontal center. The pair of reclining members 56 inserted through the end openings 35a into the path between the cover member 35 and the base cloth material 34 extend from the central opening 35b. Fixing devices 57 are fixed to the pair of reclining members 56 extending from the central opening 35b. The fixing devices 57 are sized so that they cannot pass through the central opening 35b. By providing the cover member 35 on the base fabric material 34, a path for the reclining members 56 extending laterally can be formed. This allows the reclining members 56 to stably maintain the swing position of the back support 51. As shown in FIG. 7, each reclining member 56 may be covered with a tubular cover 58.

[0034] In the stroller 10 having the seat support unit 50 and reclining mechanism 55 described above, the relative tilt angle of the back support 51 with respect to the seat support 52 can be easily changed by operating the fixing device 57. In the states shown in Figures 1, 3A, 5, and 6, the reclining member 56 is retracted into the central opening 35b, and the back support 51 is tilted backward. In the state shown in Figure 3B, the reclining member 56 is pulled out from the central opening 35b, and the back support 51 is standing up.

[0035] Next, a description will be given of the car 80. As shown in Fig. 1 to Fig. 3B, the car 80 is provided below the seat support unit 50. Fig. 8 is a perspective view of the car 80 as seen from the rear.

[0036] As shown in FIG. 8 , the basket 80 is formed by sewing a flexible fabric. Because the basket 80 is formed from a flexible material, the stroller body 11 can be folded with the basket 80 attached to the stroller body 11. In the example shown, the basket 80 is made from a fabric that is strong enough to support luggage stored in the basket 80. A strong fabric refers to a fabric that has high tear strength, burst strength, and abrasion resistance. Of course, the basket 80 may contain materials other than fabric. The basket 80 may also be made from materials other than fabric.

[0037] The car 80 has a bottom wall 81 that forms the bottom surface of the car 80. The bottom wall 81 is attached to the main body frame 12 below the seat support 52 of the seat support unit 50. In the illustrated example, the bottom wall 81 has a generally rectangular shape and has a pair of side edges 81a that extend generally in the front-to-rear direction, and a front edge 81b and a rear edge 81c that extend generally in the width direction. The front edge 81b connects the front ends of the pair of side edges 81a, and the rear edge 81c connects the rear ends of the pair of side edges 81a.

[0038] In the illustrated example, the car 80 has a pair of side wall portions 85, a front wall portion 90, and a rear wall portion 95. The pair of side wall portions 85 extend generally in the front-to-rear direction. The pair of side wall portions 85 are spaced apart from each other in the width direction. Lower edges of the side wall portions 85 are connected to corresponding side edges 81a of the bottom wall portion 81. The front wall portion 90 and the rear wall portion 95 extend generally in the width direction. Lower edges of the front wall portion 90 and the rear wall portion 95 are connected to the front edge portion 81b and the rear edge portion 81c of the bottom wall portion 81, respectively. The front edge and the rear edge of each side wall portion 85 are connected to the front wall portion 90 and the rear wall portion 95, respectively. The side wall portion 85, the front wall portion 90, and the rear wall portion 95 extend upward from the bottom wall portion 81. The side wall portion 85, the front wall portion 90, and the rear wall portion 95 form a circumferential wall. Such a peripheral wall reduces the risk of luggage contained in the basket 80 falling out of the basket 80.

[0039] Strollers are often tilted backward when going over large steps, etc., which often causes luggage stored in the basket to fall backward. Therefore, it is desirable to increase the height of the rear wall of the basket. In other words, it is desirable to increase the vertical dimension of the rear wall. In the illustrated example, the height of the rear wall 95 is higher than the height of the front wall 90. As can be seen from FIGS. 3A and 3B , at least a portion of the upper edge 95a of the rear wall 95 is located above the rear end of the seat support 52. In other words, at least a portion of the upper edge 95a of the rear wall 95 is located above the shaft member 30 that rotatably connects the third link L3 to the second link member L2 and the handle 40. This effectively reduces the risk of luggage stored in the basket 80 falling backward from between the bottom wall 81 of the basket 80 and the seat support 52.

[0040] The bottom wall 81, side wall 85, and front wall 90 of the basket 80 are attached to the main body frame 12. In the example shown in FIG. 9, a front edge 81b of the bottom wall 81 (and therefore a lower edge of the front wall 90) is connected to the front legs 14 via connectors 82. More specifically, attachment strings serving as the connectors 82 are attached to both ends of the front edge 81b of the bottom wall 81. The attachment strings 82 are inserted through through-holes 18c formed in the front wheel holding members 18a and connected to the front wheel holding members 18a. In the example shown in FIG. 10, a rear edge 81c of the bottom wall 81 (and therefore a lower edge of the rear wall 95) is connected to the rear legs 16 via connectors 83. In the example shown, attachment strings serving as the connectors 83 are attached to both ends of the rear edge 81c of the bottom wall 81. The attachment string 83 is inserted through a through-hole 19c formed in the rear wheel holding member 19a and connected to the rear wheel holding member 19a. The free ends of the attachment strings 82, 83 are prevented from slipping out of the through-holes 18c, 19c by being enlarged in size. In the illustrated example, the rear edge 81c of the bottom wall 81 (and therefore the lower edge of the rear wall 95) is connected to the rear connecting member 17 via an additional connector 84. In the illustrated example, an attachment cloth serving as the connector 84 is attached to the center of the rear edge 81c of the bottom wall 81. The attachment cloth 84 is connected to the rear connecting member 17 by being wrapped around the rear connecting member 17. The attachment cloth 84 is provided with a hook-and-loop fastener serving as a fastener 84a. The attachment cloth 84 is maintained in a state where it is wrapped around the rear connecting member 17 using the hook-and-loop fastener 84a.

[0041] In the example shown in FIG. 10 , the upper edge of the side wall 85 is connected to the rear leg 16 via a connector 86. Specifically, an attachment string serving as the connector 86 is attached to the center of the upper edge of the side wall 85. The attachment string 86 is connected to the rear leg 16 by being wound around the connection between the rear leg 16 and the fourth link L4. A ring-shaped member serving as a fastener 86a is attached to the free end of the attachment string 86. The attachment string 86 is maintained in a state where it is wound around the connection between the rear leg 16 and the fourth link L4 using the ring-shaped member 86a.

[0042] 9, the upper edge of the front wall 90 is connected to the front leg 14 via a connector 91. Specifically, attachment strings serving as the connectors 91 are attached to both ends of the upper edge of the front wall 90. The attachment strings 91 are connected to the front leg 14 by being wound around the connection between the front connecting member 25 and the front leg 14. A ring-shaped member serving as a fastener 91a is attached to the free end of the attachment string 91. The attachment string 91 is maintained in a state where it is wound around the connection between the front connecting member 25 and the front leg 14 using the ring-shaped member 91a.

[0043] However, if the height of the rear wall portion 95 is increased, there is a risk that the back support 51 and the rear wall portion 95 will interfere with each other when the seat support unit 50 is reclined, making it impossible to reclining the back support 51 to the desired position. For example, if both ends of the upper edge portion 95a of the rear wall portion 95 are connected to the main body frame 12 on both sides of the seat support unit 50, there is a risk that the back support 51, which swings relative to the main body frame 12, will interfere with the rear wall portion 95, which does not move relative to the main body frame 12, when the seat support unit 50 is reclined. In consideration of this, the rear wall portion 95 is attached to the back support 51. This allows the upper edge portion 95a of the rear wall portion 95 to move together with the back support 51. This prevents interference between the rear wall portion 95 and the back support 51 when the seat support unit 50 is reclined. Furthermore, the gap between the upper edge 95a of the rear wall 95 and the back support 51 can be maintained at a constant size regardless of the tilt angle of the back support 51. If the gap between the upper edge 95a of the rear wall 95 and the back support 51 is too large, there is a risk that luggage stored in the basket 80 will fall through the gap. If the gap between the upper edge 95a of the rear wall 95 and the back support 51 is too small, it is difficult to put luggage in or take luggage out of the basket 80 through the gap. Therefore, by maintaining a constant size of the gap between the upper edge 95a of the rear wall 95 and the back support 51 regardless of the tilt angle of the back support 51, it is possible to reduce the risk of luggage stored in the basket 80 falling through the gap, and it is also easy to put luggage in or take luggage out of the basket 80 through the gap regardless of the tilt angle of the back support 51.

[0044] In the example shown in FIGS. 8 and 11, attachment strings serving as connectors 96 are attached to both ends of the upper edge 95a of the rear wall 95. Specifically, the attachment strings 96 are connected to the back support 51 by being wound around the looped strings 34c attached to the back region 34a of the base fabric material 34. A looped member serving as a fastener 96a is provided at the free end of the attachment string 96. The attachment string 96 is maintained in a state where it is wound around the looped string 34c using the looped member 96a. Note that FIG. 11 is a plan view showing the top side of the back support 51. The top side of the back support 51 is the side opposite to the back side of the back support 51 shown in FIG. 7.

[0045] In the illustrated example, the upper edge 95a of the rear wall 95 is detachably connected to the back support 51. Specifically, the attachment string 96 is detachably connected to the loop string 34c. This allows the rear wall 95 to be removed from the back support 51 to widen the passageway for luggage into or out of the car 80 at the rear of the car 80. Therefore, large luggage can be taken in and out of the car 80 through the widened passageway.

[0046] 11, the upper edge 95a of the rear wall 95 is connected to the upper surface of the back support 51. Specifically, the looped string 34c to which the attachment string 96 is connected is attached to the upper surface of the base cloth material 34. Therefore, the attachment string 96 passes on the widthwise outer side of the back support 51 and is connected to the upper surface of the back support 51. In the illustrated example, the attachment string 96 passes on the widthwise outer side of a pair of side frame portions 31a of the back frame member 31 and is connected to the upper surface of the base cloth material 34. This allows the upper edge 95a of the rear wall 95 to be maintained in a state in which it is expanded to approximately the same width dimension as the back support 51. As a result, the risk of luggage stored in the basket 80 falling rearward from between the rear legs 16 is effectively reduced.

[0047] 11, the upper edge 95a of the rear wall 95 is located below the path of the reclining member 56 on the back side of the back support 51. This reduces the risk that the rear wall 95 will interfere with the operation of the reclining member 56 (particularly the fixing device 57) when reclining the seat support unit 50.

[0048] In the example shown in FIG. 8 , an insertion passage 97 extending in the width direction is formed in the upper edge 95a of the rear wall 95. More specifically, the upper edge 95a of the rear wall 95 is formed in a cylindrical shape, and the internal space of the cylindrical upper edge 95a forms the insertion passage 97. A rubber string 98 is inserted through the insertion passage 97. Both ends of the rubber string 98 are fixed to both ends of the upper edge 95a of the rear wall 95. The upper edge 95a of the rear wall 95 expands and contracts in response to expansion and contraction of the rubber string 98. This contracts the upper edge 95a of the rear wall 95 to reduce the gap between the upper edge 95a and the seat support unit 50, thereby reducing the risk of luggage falling through the gap. Furthermore, by expanding the upper edge 95a as needed, the gap between the upper edge 95a and the seat support unit 50 can be expanded, allowing luggage to be loaded and unloaded through the gap.

[0049] In the illustrated example, a plate member 99 is disposed within the insertion passage 97. As can be seen from FIG. 8 , the vertical dimension of the plate member 99 is greater than the vertical dimension of the rubber cord 98. The plate member 99 is fixed to the rear wall portion 95 within the insertion passage 97. The plate member 99 is made of, for example, polypropylene and is flexible. The rubber cord 98 is located behind the plate member 99. As a result, by pulling the plate member 99 rearward, the rubber cord 98 is pulled rearward and stretched, and the upper edge portion 95a of the rear wall portion 95 stretches. In other words, by pulling the plate member 99 rearward, the rubber cord 98 is stretched, and the gap between the upper edge portion 95a of the rear wall portion 95 and the seat support unit 50 can be enlarged. As described above, the vertical dimension of the plate material 99 is larger than the vertical dimension of the rubber band 98, so when operating the upper edge portion 95a of the rear wall portion 95, it is easier to grasp the plate material 99 than to grasp the rubber band 98.

[0050] Because the upper edge 95a of the rear wall 95 is attached to the back support 51, the upper edge 95a of the rear wall 95 is located behind the seat support 52 in a side view of the stroller 10. In addition, because the lower edge of the rear wall 95 is connected to the rear legs 16, the rear wall 95 extends between the back support 51 and the rear legs 16 in a side view of the stroller 10.

[0051] In the illustrated example, as shown in Figure 3A, when the back support 51 is in the most reclined position relative to the main body frame 12, the attachment string 96 connecting the rear wall 95 and the back support 51 is located forward of the rotation axis 19b of the rear wheels 19 held at the lower end portions of the rear legs 16. This reduces the risk that the center of gravity of luggage stored in the basket 80 will be behind the rotation axis 19b of the rear wheels 19, and reduces the risk of the stroller 10 unintentionally tipping backward.

[0052] In the example shown in FIG. 8 , the side wall 85 has a front side wall 87 that forms a front region and a rear side wall 88 that forms a rear region. A front edge of the front side wall 87 is connected to the front wall 90. A rear edge of the rear side wall 88 is connected to the rear wall 95. In the example shown, the connection position of the front side wall 87 and the rear side wall 88 in the front-to-rear direction is approximately the same as the connection position of the rear leg 16 and the fourth link L4 in the front-to-rear direction. The height of the front side wall 87 is the same as the height of the front wall 90. The height of the rear side wall 88 is higher than the height of the front side wall 87. In the example shown, the rear side wall 88 extends to an upper edge 95a of the rear wall 95. The rear side wall 88 extends between the rear leg 16 and the rear wall 95 in a side view of the stroller 10. Such a rear side wall portion 88 further effectively reduces the risk of baggage contained in the basket 80 falling rearward.

[0053] In the illustrated example, the bottom wall 81, front wall 90, and lower regions of the rear wall 95 of the basket 80 are integrally formed from a first cloth material I. Furthermore, the lower regions of the front side wall 87 and the rear side wall 88 are integrally formed from a second cloth material II. The region other than the lower region of the rear side wall 88 and the intermediate region of the rear wall 95 are integrally formed from a third cloth material III. The intermediate region of the rear wall 95 is the region between the lower region and the upper edge 95a of the rear wall 95. The upper edge 95a of the rear wall 95 is formed from a fourth cloth material IV. The internal space of the cylindrically formed fourth cloth material IV forms the insertion passage 97. As described above, the bottom wall 81 is formed from a portion of the first cloth material I. Furthermore, the front wall 90 is formed from a portion of the first cloth material I. Furthermore, the rear side wall 88 is formed from a portion of the second cloth material II and a portion of the third cloth material III. The rear wall portion 95 is formed by a part of the first cloth material I, a part of the third cloth material III, and a fourth cloth material IV.

[0054] In the embodiment described above, the stroller 10 comprises a stroller body 11 including front legs 14 and rear legs 16, and a basket 80 attached to the stroller body 11. The stroller body 11 includes a body frame 12 including the front legs 14 and rear legs 16, and a seat support unit 50 supported by the body frame 12 and having a seat support 52 and a back support 51. The back support 51 is swingable relative to the body frame 12. The basket 80 includes a bottom wall 81 located below the seat support 52, and a rear wall 95 connected to a rear edge 81c of the bottom wall 81. The rear wall 95 is attached to the back support 51.

[0055] According to this embodiment, the rear wall 95 can reduce the risk of luggage stored in the basket 80 falling rearward from the basket 80. Furthermore, even if the vertical dimension of the rear wall 95 of the basket 80 is increased, there is no problem in that the back support 51 and the rear wall 95 interfere with each other when reclining the seat support unit 50, preventing the back support 51 from being tilted to the desired position. This is because the rear wall 95 is attached to the back support 51, and therefore the upper edge 95a of the rear wall 95 moves together with the back support 51 when reclining the seat support unit 50.

[0056] In the embodiment described above, at least a portion of the upper edge 95a of the rear wall 95 is located higher than the rear end of the seat support 52. This effectively reduces the risk that luggage stored in the basket 80 will fall rearward from between the bottom wall 81 of the basket 80 and the seat support 52.

[0057] In the embodiment described above, the stroller body 11 has the first link L1, the front legs 14 connected to the first link L1 and rotatable relative to the first link L1, the rear legs 16 connected to the first link L1 and rotatable relative to the first link L1, and the handle 40 connected to the first link L1 and rotatable relative to the first link L1. This allows the stroller body 11 to be folded, thereby reducing the dimensions of the stroller 10.

[0058] Furthermore, in the embodiment described above, the basket 80 further has a side wall portion 85 connected to the side edge portion 81a of the bottom wall portion 81. At least a portion of the side wall portion 85 is connected to the rear wall portion 95 and extends between the rear legs 16 and the rear wall portion 95 in a side view of the stroller 10. This further effectively reduces the risk of luggage stored in the basket 80 falling rearward.

[0059] In the embodiment described above, the attachment string 96 for attaching the rear wall portion 95 to the back support 51 passes along the widthwise outer side of the back support 51 and connects to the upper surface of the back support 51. In the illustrated example, the back support 51 includes a frame member 31 having a pair of side frame portions 31a spaced apart in the widthwise direction, and a base cloth material 34 stretched across the frame member 31. The attachment string 96 for attaching the rear wall portion 95 to the back support 51 passes along the widthwise outer side of the pair of side frame portions 31a and connects to the upper surface of the base cloth material 34. This allows the upper edge 95a of the rear wall portion 95 to be maintained in a state that is approximately the same as the widthwise dimension of the back support 51. As a result, the risk of luggage stored in the basket 80 falling rearward between the rear legs 16 is effectively reduced.

[0060] Furthermore, in the embodiment described above, when the back support 51 is in the most reclined position relative to the main body frame 12, the attachment cord 96 is located forward of the rotation axis 19b of the rear wheels 19 held at the lower end portions of the rear legs 16. This reduces the risk that the center of gravity of luggage stored in the basket 80 will be behind the rotation axis 19b of the rear wheels 19, and reduces the risk of the stroller 10 unintentionally tipping backward.

[0061] In the embodiment described above, an insertion passage 97 extending in the width direction is formed in the upper edge 95a of the rear wall 95. An elastic cord 98 is inserted through the insertion passage 97. This allows the upper edge 95a of the rear wall 95 to expand and contract in accordance with the expansion and contraction of the elastic cord 98. As a result, by contracting the upper edge 95a of the rear wall 95 and reducing the gap between the upper edge 95a and the seat support unit 50, it is possible to reduce the risk of luggage falling through the gap. Furthermore, by expanding the upper edge 95a to expand the gap between the upper edge 95a and the seat support unit 50 as needed, it is possible to load and unload luggage through the gap.

[0062] In the embodiment described above, a plate member 99 is disposed inside the insertion passage 97. The rubber cord 98 is located behind the plate member 99. This allows the rubber cord 98 to be stretched by pulling the plate member 99 rearward. Therefore, it is easy to stretch the rubber cord 98 and increase the gap between the upper edge portion 95a and the seat support unit 50.

[0063] Furthermore, in the embodiment described above, the stroller 10 further includes reclining members 56 that are connected to the main frame 12 on both sides of the back support 51 and pass through the back side of the back support 51 to support the back side of the back support 51. The upper edge 95a of the rear wall 95 is located below the path of the reclining members 56 on the back side of the back support 51. This prevents the rear wall 95 from interfering with the operation of the reclining members 56 when reclining the seat support unit 50.

[0064] Although several modifications of the above-described embodiment have been described, it is of course possible to combine a plurality of modifications as appropriate. [Explanation of symbols]
