Description

Push cart

[0001] The present invention relates to a push cart.

[0002] When taking babies or pets out, push carts such as strollers and pet carts are used (see, for example, JP2018-114796A). For a push cart to smoothly overcome bumps on the traveling surface, it is effective to lift the wheels located at the front in the traveling direction. To lift the wheels, it is effective to place a foot on a cross member provided near the wheel located at the rear in the traveling direction of the push cart, and then pull the handle of the push cart backward and downward. Here, the cross member is a member extending in the width direction, and an example of this is a member connecting a pair of rear legs.

[0003] However, many push carts have a basket member attached to the bottom. The basket member is attached to the push cart by wrapping a string-like attachment member around the crossover member. However, when the attachment member is wrapped around the crossover member, it is difficult to place one's foot on the crossover member.

[0004] The present invention has been made in consideration of the above points, and an object of the present invention is to provide a platform on which a car member is attached so that a foot can be placed stably.

[0005] The push cart according to the present invention comprises a cart body having a pair of legs spaced apart in the width direction, wheels held at the lower end portions of each of the pair of legs, a cross member extending in the width direction between the pair of legs or the pair of wheels, and a footrest member provided on the cross member; and a basket member attached to the cart body, wherein the basket member has a basket main body portion forming a storage section and an attachment member extending from the basket main body portion and attaching the basket main body portion to the cart body, and a passageway for the attachment member is formed between the cross member and the footrest member.

[0006] According to the present invention, it is possible to stably place one's feet on the cross member to which the basket member is attached.

[0008] In the following, a stroller used for taking babies and small children will be described as an example of a push cart. However, the present invention is not limited to strollers and can be widely used for carts that are configured to be pushed by the user's hands, such as a push cart configured as a pet cart used to transport pets.

[0009] Figures 1 to 9 are diagrams illustrating one embodiment of the present invention. Of these, Figures 1 to 4 show the overall configuration of a stroller as a specific example of a push cart, or the overall configuration of a stroller body as a specific example of a cart body. Also, Figures 4A to 5 show the cross members and foot rest members included in the stroller body (cart body), and Figures 6 to 8 show the foot rest members. Note that components shown in some figures may be omitted in other figures.

[0010] As shown in Figures 1 and 2, the stroller (push cart) 10 of this embodiment has a stroller body (cart body) 15 and a basket member 70 supported by the stroller body 15. As shown in Figure 2, which shows the stroller 10 from the rear, the stroller body 15 has a cross member 25 extending in the width direction and foothold members 40 provided on the cross member 25. The stroller 10 described below is designed to allow stable footholds on the cross member 25 to which the basket member 70 is attached.

[0011] Below, we will explain each component of the stroller 10 in order. As shown in Figure 1, the stroller 10 and stroller body 15 shown in the figure are generally symmetrical overall with respect to a plane that is located in the center in the lateral direction and that extends in the front-to-back and up-to-down directions.

[0012] In this specification, the terms "front," "rear," "up," "down," "front-to-back direction," and "vertical direction" with respect to a stroller (push cart) 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 pages in Figures 1 and 2, and corresponds to the left-to-right direction of the page in Figure 3. Unless otherwise specified, "front" refers to the side toward which an infant riding in the stroller faces, with the lower left side of the page in Figure 1, the upper right side of the page in Figure 2, and the left side of the page in Figure 3 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."

[0013] 1, the stroller 10 includes, in addition to the stroller body 15 and the basket member 70, a seat 60 supported by the stroller body 15. The seat 60 is a location on which a baby sits or lies down.

[0014] Next, the stroller body 15 will be described with reference to Figures 1 to 4. This stroller body 15 is configured to be foldable. The stroller body 15 has a pair of front legs 21 arranged on the left and right, and a pair of rear legs 23 arranged on the left and right. The stroller body 15 also 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 21, the rear legs 23, and the first to fourth links L1 to L4 function as links that configure the stroller body 15 to be foldable and unfoldable.

[0015] 1 and 2 , the front legs 21 rotatably support front wheels 22 at their lower end portions. The front wheels 22 form casters and are rotatable and swivelable. The rear legs 23 rotatably support rear wheels 24 at their lower end portions. The front legs 21 and the rear legs 23 may be made of metal pipes such as aluminum alloy pipes.

[0016] As shown in Figures 1 and 2, the upper end portions of the front legs 21 are rotatably (swingably) connected to the front portion of the first link L1 located on the corresponding side (left or right). The upper end portions of the rear legs 23 are rotatably (swingably) connected to the front portion of the first link L1 located on the corresponding side (left or right). The first link L1 may be formed using, for example, a resin molded part. In the illustrated example, the first link L1 may function as an armrest.

[0017] As can be seen from Fig. 3, the second link L2 is rotatably (swingably) connected to the rear end portion of the first link L1 located on the corresponding side (left or right). In the illustrated example, the second link L2 is configured as part of the handle 30. The handle 30 has an overall U-shape. The handle 30 has a pair of shafts 31 and a connecting portion 32 that connects the pair of shafts 31. Each shaft 31 constitutes the second link L2. The connecting portion 32 connects the upper end portions of the pair of shafts 31. The handle 30 can be configured using a metal pipe such as an aluminum alloy.

[0018] As shown in Figure 2, the third link L3 is rotatably connected to the rear leg 23 located on the corresponding side (left or right). The third link L3 may be formed using, for example, a metal pipe made of aluminum alloy or the like or a resin molded part. In the illustrated example, the third link L3 is rotatably connected at its lower end to the middle part of the rear leg 23.

[0019] 2 and 3, the fourth link L4 is rotatably connected to the front leg 21 arranged on the corresponding side (left or right). In the example shown, the front end portion of the fourth link L4 is rotatably connected to the middle portion of the front leg 21. The fourth link L4 constitutes a part of the seat support unit that supports the seat 60.

[0020] In the illustrated example, the second link L2, the third link L3, and the fourth link L4, which are arranged on the same side (left or right) in the width direction, are rotatably connected to one another using the same shaft member 35 (see FIG. 3). This shaft member 35 passes through the second link L2, the third link L3, and the fourth link L4. With this configuration, the second link L2, the third link L3, and the fourth link L4 are rotatable relative to one another about an axis that coincides with the central axis of the shaft member 35.

[0021] The stroller body 15 has a seat support unit 38 as a component for supporting the seat 60. As shown in FIG. 3, the seat support unit 38 has a seat support 38A and a back support 38B. The back support 38B is pivotable relative to the seat support 38A. The seat support 38A includes a pair of side frame elements 39a and a front frame member 39b and a rear frame member 39c that connect the pair of side frame elements 39a (see FIG. 2). The pair of side frame elements 39a are spaced apart in the width direction. Each side frame element 39a extends in the front-to-rear direction and constitutes the fourth link L4 described above. The front frame member 39b extends in the width direction and connects the front end portions of the pair of side frame elements 39a. The rear frame member 39c extends in the width direction and connects the rear end portions of the pair of side frame elements 39a.

[0022] Furthermore, the stroller body 15 has a lateral member extending laterally between a pair of legs or a pair of wheels. The illustrated stroller body 15 has a front connecting member 26 (see FIG. 1) that connects the pair of front legs 21 and a rear connecting member 27 (see FIG. 2) that connects the pair of rear legs 23. The front connecting member 26 functions as a footrest. The front connecting member 26 and the rear connecting member 27 may be made of, for example, a metal pipe such as an aluminum alloy or a resin molded part. In addition, a flexible guard member 28 is removably provided between the pair of first links L1.

[0023] 2, in the illustrated example, a foothold member 40 is provided on the cross member 25 formed by the rear connecting member 27. The foothold member 40 will be described in detail later.

[0024] The stroller body 15 having the above configuration can be folded by rotating each component relative to the other. Specifically, the handle 30 constituting the second link L2 is first pulled upward and rearward, and then pushed downward, thereby rotating the third link L3 clockwise in FIG. 3 relative to the rear legs 23. This operation causes the first link L1 and the fourth link L4 to rotate clockwise in FIG. 3 relative to the second link L2. This operation moves the handle 30 and the front legs 21 closer to each other while maintaining a substantially parallel relationship in a side view, and lowers the position of the handle 30. The stroller body 15 can be folded in this manner. In the folded state, the dimensions of the stroller 10 in the front-to-rear and up-to-down directions can be reduced. To unfold the stroller body 15 from the folded state, the above-described folding procedure can be reversed.

[0025] The seat 60 and basket member 70 attached to the stroller body 15 are flexible. Therefore, the seat 60 and basket member 70 deform as the stroller body 15 is folded and unfolded, and do not interfere with these operations of the stroller body 15.

[0026] Next, the basket member 70 attached to the stroller body 15 will be described.

[0027] The basket member 70 provides a storage section that functions as a storage space. There are no particular limitations on what can be stored in the storage section of the basket member 70, and various items that are allowable depending on the configuration of the basket member 70, such as a lap blanket or toys, may be stored. The basket member 70 has a basket main body 71 that forms the storage section, and an attachment member 72 that extends from the basket main body 71. The basket main body 71 may be configured as a sewn product. The attachment member 72 is a member for attaching the basket main body 71 to the stroller main body (cart main body) 15.

[0028] Various configurations may be employed for the attachment member 72. For example, the attachment member 72 may be configured as an elongated string-like or belt-like member, and such a string-like or belt-like member may further include a fastener such as a hook-and-loop fastener, a button, or a clip, or may be configured solely with a fastener.

[0029] As shown in FIG. 2 , the illustrated attachment member 72A is constructed by folding back a sewn belt material at the tip away from the basket body 71, and can be considered a belt-like member overall. The belt material is sewn only at the tip of the belt-like member, maintaining the belt material in a folded state. Therefore, the tip of the belt material is curved back slightly away from the opposing belt material, and the tip portion of the belt-like member may have a tapered outer shape toward the tip. With this attachment member 72A, when the folded portion of the belt material is passed through the retaining hole 16 provided in the stroller body 15, the tip of the belt material is prevented from expanding and freely slipping out of the retaining hole 16. Meanwhile, by holding down the tip of the belt material, the attachment member 72A can be removed from the retaining hole 16 of the stroller body 15.

[0030] 2 has four first attachment members 72A extending upward from the basket main body 71 and three attachment members 72B, 72C extending downward and rearward from the basket main body 71. The first attachment members 72A extending upward from the basket main body 71 are held to the stroller main body 15 by passing through holding holes 16 provided in a pair of third links L3 and a pair of fourth links L4. By using the first attachment members 72A, the basket member 70 is held in a suspended state from the stroller main body 15.

[0031] Three attachment members 72B, 72C extend downward and rearward from the basket main body 71 and are spaced apart in the width direction. The second attachment members 72B located on both sides are held to the stroller main body 15 by passing through the rear connecting members 27 or the retaining holes 16 provided in the rear wheels 24. Meanwhile, the third attachment member 72C located in the center in the width direction has a different configuration from the other attachment members 72A. The third attachment member 72C is configured as a belt-like member with fasteners such as hook-and-loop fasteners. As shown in Figures 4A to 4C, the third attachment member 72C is attached to the crossover member 25 by going around the crossover member 25 and forming a loop-shaped portion through which the crossover member 25 passes using fasteners (not shown).

[0032] The three attachment members 72B, 72C extending downward, and particularly the third attachment member 72C located in the center in the width direction, can stabilize the position of the basket member 70 suspended from the stroller body 15. This prevents the basket body 71 containing items and the like from shaking, and effectively prevents the stroller 10 from becoming unstable when the basket body 71 shakes.

[0033] Furthermore, the third attachment member 72C located in the center in the width direction can effectively prevent the bottom of the basket main body 71 from deforming and coming into contact with the running surface due to, for example, heavy items stored in the basket main body 71. In particular, in the basket member 70 shown in Figure 3, the bottom of the basket main body 71 is inclined so that it is positioned downward toward the rear. When attaching the stroller body 15 to such a basket main body 71, the above-mentioned effects of the third attachment member 72C become even more pronounced.

[0034] Next, the footrest members 40 provided on the crossover members 25 will be described in detail. The footrest members 40 are portions on which the feet of a user of the stroller (push cart) 10 are placed. In a push cart configured as the stroller 10, the user, acting as a guardian of an infant riding in the stroller 10, places their feet on the footrest members 40 when steering the stroller 10.

[0035] The running surface TP (see FIG. 3 ) on which the stroller cart 10 travels may have a step. To smoothly overcome this step, it is effective to lift the wheels positioned in front of the stroller cart in the direction of travel while the stroller is moving. Otherwise, the wheels in front of the stroller cart will collide with the step, preventing the stroller from moving. Also, when crossing a railroad crossing, for example, the running surface TP may have a groove or other depression. In such a situation, it is also effective to lift the wheels positioned in front of the stroller cart in the direction of travel while the stroller is moving. Otherwise, the wheels in front of the stroller cart will get stuck in the depression, preventing the stroller from moving.

[0036] As shown by the thick arrow in Figure 3, the user pulls the handle 30 downward and backward to lift the wheel 22 at the front in the direction of travel. At this time, the user can prevent the push cart 10 itself from moving backward by placing their feet on the footrests 40. Placing their feet on the footrests 40 encourages the push cart 10 as a whole to rotate clockwise in Figure 3 around the rotation axis of the wheel located at the rear in the direction of travel, thereby lifting the wheel 22 at the front in the direction of travel.

[0037] As shown in FIG. 2 , the footrest 40 extends along the width direction and is provided on only a portion of the entire width of the crossover member 25, which is formed by the rear connecting member 27. Also, as shown in FIG. 4A , when viewed from the width direction, the footrest 40 is provided on only a portion of the entire circumference of the crossover member 25. That is, the footrest 40 does not encircle the crossover member 25. According to this specific example, a user who sees the footrest 40 can visually recognize that the footrest 40 is a location on which to place a foot, which allows the user to effectively use the footrest 40. That is, when going over a step or a recess, the user places their foot on the footrest 40, which allows the front wheel 22, which is held by the front leg 21 in the forward direction of travel, to rise. As a result, the vehicle can stably go over uneven surfaces such as steps and recesses.

[0038] In the illustrated example in particular, the footrest 40 is located on a portion of the crossover member 25 that includes the center of the crossover member 25 in the width direction. Therefore, by placing a foot on the footrest 40, the stroller 10 is prevented from swaying from side to side, and the front wheels 22 can be lifted stably.

[0039] 4A to 4C, the footrest 40 is attached to the crossover member 25 so as to cover the highest position of the crossover member 25 in the up-down direction from above when viewed from the width direction. According to this specific example, the crossover member 25 can stably support the footrest 40 from below. Therefore, when a foot is placed on the footrest 40, the footrest 40 can be effectively prevented from coming off the crossover member 25.

[0040] 4B and 4C show the cross member 25 and the foothold member 40 in cross sections along both the up-down direction and the front-to-rear direction, i.e., in cross sections perpendicular to the width direction. 4B and 4C show cross sections at different positions in the width direction. More specifically, FIG. 4B shows the foothold member 40 together with the cross member 25 in a cross section taken along line B-B in FIG. 7, and FIG. 4C shows the foothold member 40 together with the cross member 25 in a cross section taken along line CC in FIG. 7.

[0041] However, the installation position of such foothold member 40 on crossover member 25 overlaps with the installation position of third attachment member 72C on crossover member 25, which is important for stably holding car main body 71. If third attachment member 72C is wrapped around foothold member 40 together with crossover member 25, it is not possible to place a foot on foothold member 40 stably, and in the first place, there is a possibility that third attachment member 72C may become soiled, which may discourage people from placing their feet on foothold member 40 at all.

[0042] In contrast, according to this embodiment, as shown in FIGS. 4B and 4C , a passage path PW for the third attachment member 72C is formed between the crossover member 25 and the footrest member 40. Therefore, the third attachment member 72C can pass through the passage path PW between the inner surface of the crossover member 40 and the crossover member 25 without passing over the outer surface of the crossover member 40. This prevents the third attachment member 72C from getting between the footrest member 40 and the foot. Furthermore, the footrest member 40 is attached to the crossover member 25 so as to cover the highest position of the crossover member 25 in the vertical direction from above when viewed from the width direction. This allows for stable application of force to the crossover member 25 via the footrest member 40. This allows the front wheel 22, held by the leg 21 at the front in the traveling direction, to be easily lifted. As a result, unevenness formed on the running surface TP (see FIG. 3 ) can be stably overcome.

[0043] Additionally, it is possible to effectively prevent the third attachment member 72C from becoming soiled by shoes or the like placed on the foothold member 40. Furthermore, because the third attachment member 72C is disposed on the passage path PW formed between the foothold member 40 and the crossover member 25, it is possible to prevent the third attachment member 72C from shifting position on the crossover member 25 and further prevent the third attachment member 72C from becoming detached from the crossover member 25. This also makes it possible to more stably hold the car main body 71 using the third attachment member 72C.

[0044] Next, the footrest member 40 will be described. As shown in FIGS. 4A to 4C , when viewed from the width direction, the footrest member 40 covers approximately half of the entire circumference of the crossover member 25. In the illustrated example, the rear connecting member 27 constituting the crossover member 25 has a flat portion 25a with a flat outer surface and a curved portion 25b with a curved outer surface. In particular, in the illustrated crossover member 25, the outer surface of one curved portion 25b is semicircular. A pair of flat portions 25a connects the ends of the two curved portions 25b. As a result, in a cross section perpendicular to the width direction, the crossover member 25 has a major axis LA parallel to the direction in which the pair of flat portions 25a extend and a minor axis SA parallel to the direction in which the pair of flat portions 25a face each other. The major axis LA and the minor axis SA are orthogonal to each other. The long axis LA extends along the central axis of the rear leg 23 to which the cross member 25 (rear connecting member 27) is attached, and is inclined relative to the vertical direction so as to be positioned at the top and forward.

[0045] The footrest 40 covers the rearward and somewhat upper half of the cross member 25, as defined by the longitudinal axis LA. In particular, the illustrated footrest 40 covers an area exceeding the rearward and somewhat upper half of the cross member 25, as defined by the longitudinal axis LA. Such footrest 40 can easily be attached to and secured to the cross member 25, while still covering the required area of ​​the cross member 25.

[0046] 4B and 4C , when viewed from the width direction, the passage path PW extends linearly on the flat portion 25a along the outer surface of the crossover member 25 and extends curvedly on the curved portion 25b. Furthermore, as shown in FIG. 5 , the passage path PW has openings facing forward and slightly downward at both ends. Because the passage path PW has a pair of openings, the third attachment member 72C can be attached to and detached from the crossover member 25 when the foothold member 40 is fixed on the crossover member 25.

[0047] More specifically, during attachment, the third attachment member 72C is inserted into the passageway PW through one of the openings, allowing the third attachment member 72C to pass through the passageway PW. Then, the tip of the third attachment member 72C that has passed through the passageway PW is fastened to the portion of the third attachment member 72C that is located between the passageway PW and the basket main body 71 using a fastener such as a hook-and-loop fastener, button, or clip. This allows the third attachment member 72C extending from the basket main body 71 to be attached to the cross member 25. During removal, the portion of the third attachment member 72C that has passed through the passageway PW is retracted into the passageway PW, and then the third attachment member 72C is pulled out from the passageway PW. Making the basket member 70 detachable from the stroller main body 15 allows the basket member 70 to be kept clean by washing, for example.

[0048] The foothold member 40 will be described in more detail with reference to Figures 5 to 8. Figure 5 is a front view of the foothold member 40 attached to the crossover member 25. Figure 6 is a perspective view of the foothold member 40 alone, with the crossover member 25 removed. Figure 7 is a plan view of the foothold member 40 from the side facing the crossover member 25, and Figure 8 is a cross-sectional view taken along line XIII-XIII in Figure 7.

[0049] As can be seen from FIGS. 5 and 7 , the foothold member 40 includes a pair of first portions (first regions) 41 located at both ends in the width direction and attached to the cross member 25, and a second portion (second region) 42 located between the pair of first portions 41 in the width direction. The second portions 42 form a passageway PW between the foothold member 40 and the cross member 25. As shown in FIG. 2 , the first portions 41 of the foothold member 40 are attached to the cross member 25 using fasteners such as screws or rivets. In this specific example, the first portions 41 attached to the cross member 25 restrict the position of the third attachment member 72C from shifting in the width direction. This prevents the third attachment member 72C from unintentionally coming off the cross member 25 and further allows the third attachment member 72C to be stably held on the cross member 25.

[0050] As can be seen from Figures 2 and 8, the second portion 42 of the footrest 40 protrudes more from the cross member 25 than the first portion 41. That is, the footrest 40 protrudes more from the second portion 42, which is located between the pair of first portions 41. In other words, the thickness of the footrest 40 is greater at the second portion 42 than at the first portion 41. This external shape of the footrest 40 makes it easier for the user to place their foot on the second portion 42. By placing their foot in an area centered on the second portion 42, which is the middle portion of the footrest 40 in the width direction, a force can be applied more stably to the cross member 25 via the footrest 40.

[0051] In particular, the second portion (second region) 42 of the foothold member 40 may be positioned at the widthwise center of the crossover member 25. With this configuration, force can be applied more stably to the crossover member 25 via the foothold member 40. Furthermore, the third attachment member 72C is positioned at the widthwise center, allowing the car main body 71 to be attached more stably.

[0052] 2 and 8, the height to which the foothold member 40 protrudes from the crossover member 25 increases from both ends in the width direction toward the center in the width direction. In other words, the thickness of the foothold member 40 increases from both ends in the width direction toward the center in the width direction. This external shape of the foothold member 40 makes it easier to place the foot on the second portion 42, and allows for more stable application of force to the crossover member 25 via the foothold member 40.

[0053] As shown in FIG. 6 , the foothold member 40 has a plate-shaped portion 45 that covers the cross member 25 , and a first rib 51 that protrudes from the plate-shaped portion 45 toward the cross member 25 in the first portion 41 .

[0054] The plate-like portion 45 is a plate-like portion having a planar expanse. However, holes or the like may be provided in the plate-like portion 45. The plate-like portion 45 shown in FIG. 2 is curved. As shown in FIG. 2, the plate-like portion 45 has an outer rib 46 on its outer surface facing away from the cross member 25. A plurality of outer ribs 46 (three ribs in the illustrated example) are provided spaced apart in a direction perpendicular to the width direction. The outer ribs 46 function as anti-slip devices for shoes (feet) placed on the foothold member 40. The outer ribs 46 visually inform the user of the position where the foot should be placed.

[0055] 4B and 5, the first rib 51 extending from the plate-like portion 45 in the first section 41 contacts the cross member 25 at its tip, which is the farthest from the plate-like portion 45. Such a first rib 51 allows the foothold member 40 to be made smaller and lighter while still maintaining sufficient rigidity. Furthermore, by maintaining the first rib 51 in contact with the cross member 25, the foothold member 40 can be stably positioned on the cross member 25. Furthermore, the position of the third attachment member 72C can be effectively prevented from shifting in the width direction.

[0056] As shown in Figures 6 and 8, the first rib 51 includes a first vertical rib 51a and a first horizontal rib 51b. As shown in Figures 4B and 4C, the first vertical rib 51a extends along the outer surface of the cross member 25 when viewed from the width direction. The first horizontal rib 51b extends in the width direction. With this configuration, the foothold member 40 can be made sufficiently small and lightweight while maintaining sufficient rigidity.

[0057] In particular, in the illustrated example, as shown in FIGS. 4B and 4C , the first vertical rib 51 a extends in a curved line along the outer surface of the cross member 25 when viewed from the width direction. As shown in FIGS. 6 to 8 , the first portion 41 has a plurality of first vertical ribs 51 a spaced apart in the width direction. The first cross ribs 51 b extend linearly in the width direction. The first portion 41 has a plurality of first cross ribs 51 b spaced apart in a direction perpendicular to the width direction. As can be seen from FIG. 6 , the plurality of first cross ribs 51 b are spaced apart along the outer surface of the cross member 25 when viewed from the width direction. As shown in FIGS. 4B , 4C , and 7 , the first vertical ribs 51 a and the first cross ribs 51 b extend from the plate-shaped portion 45 along a plane perpendicular to the width direction. Furthermore, the first portion 41 has through-holes 51 c through which fasteners such as screws and rivets pass to attach the foothold member 40 to the cross member 25.

[0058] As shown in FIG. 6 , the foothold member 40 has a second rib 52 that protrudes from the plate-shaped portion 45 toward the cross member 25 in the second section 42. As shown in FIG. 6 , the protruding height of the second rib 52 from the plate-shaped portion 45 is smaller than the protruding height of the first rib 51 from the plate-shaped portion 45. As a result, as shown in FIGS. 4B , 4C , and 5 , the tip of the second rib 52, which is farthest from the plate-shaped portion 45, is separated from the cross member 25. A passage path PW is formed between the tip of the second rib 52 and the cross member 25. Therefore, the difference between the protruding height of the first rib 51 from the plate-shaped portion 45 and the protruding height of the second rib 52 from the plate-shaped portion 45 is approximately the same as the thickness of the passage path PW and is greater than or equal to the thickness of the third attachment member 72C that passes through the passage path PW.

[0059] In the illustrated example, the distance from the tip of the second rib 52 to the cross member 25 is approximately constant. This makes the thickness of the passage path PW approximately constant at the position facing the second rib 52. This configuration makes it possible to prevent the third attachment member 72C from becoming clogged in the passage path PW, particularly when the tip of the third attachment member 72C is inserted into the passage path PW during attachment of the third attachment member 72C.

[0060] As shown in Figures 6 and 8, the second rib 52 includes a second vertical rib 52a and a second horizontal rib 52b. As shown in Figures 4B and 4C, the second vertical rib 52a extends along the outer surface of the crossover member 25 when viewed in the width direction. The second horizontal rib 52b extends in the width direction. This configuration allows the foothold member 40 to be sufficiently lightweight while maintaining sufficient rigidity. As shown in Figures 4B, 4C, and 7, the second vertical rib 52a and the second horizontal rib 52b extend from the plate-like portion 45 along a plane perpendicular to the width direction.

[0061] 4B and 4C , the second vertical rib 52a extends in a curved shape along the outer surface of the crossover member 25 while being spaced apart from the crossover member 25 when viewed from the width direction. According to this specific example, when the third attachment member 72C is attached to or detached from the crossover member 25, the second vertical rib 52a can guide the third attachment member 72C along the passage path PW between the crossover member 25 and the foothold member 40. This makes it easy to attach the basket member 70 to the stroller body 15 using the third attachment member 72C.

[0062] In the illustrated example, the distance from the tip of the second vertical rib 52a to the cross member 25 is generally constant at each position along the outer surface of the cross member 25 when observed in the width direction. This configuration allows the third attachment member 72C to move smoothly through the passage path PW when attaching and detaching the third attachment member 72C to and from the cross member 25.

[0063] 4B and 4C, the protruding height of the second vertical rib 52a from the plate-like portion 45 gradually decreases toward both ends 52ae at both end portions along the outer surface of the crossover member 25 when viewed from the width direction. According to this specific example, the change in height of the second vertical rib 52a can smoothly guide the insertion of the third attachment member 72C into the passage path PW between the crossover member 25 and the footrest member 40. This makes it easy to attach the basket member 70 to the stroller body 15 using the third attachment member 72C.

[0064] As shown in Figures 6 to 8, the second portion 42 of the foothold member 40 is provided with multiple second vertical ribs 52a. The multiple second vertical ribs 52a are spaced apart in the width direction. As shown in Figures 7 and 8, the arrangement pitch P2 of the multiple second vertical ribs 52a is smaller than the arrangement pitch P1 of the multiple first vertical ribs 51a. This configuration ensures sufficient strength in the second portion 42 of the foothold member 40, which is spaced apart from the crossover member 25. This allows the force applied to the foothold member 40 to be efficiently transmitted to the crossover member 25. Furthermore, the third attachment member 72C is more easily supported by two or more second vertical ribs 52a within the passage path PW between the crossover member 25 and the foothold member 40. This stabilizes the state of the third attachment member 72C within the passage path PW, allowing the basket member 70 to stably hold items and the like. In addition, when the third mounting member 72C is attached to or detached from the cross member 25, the two or more second vertical ribs 52a can stably guide the third mounting member 72C along the passage path PW between the cross member 25 and the foothold member 40.

[0065] More preferably, the arrangement pitch P2 of the plurality of second vertical ribs 52a is smaller than the width W of the belt-like third attachment member 72C shown by the two-dot chain line in each of Figures 7 and 8. According to this specific example, the third attachment member 72C is supported by two or more second vertical ribs 52a within the passage path PW between the cross member 25 and the foothold member 40. This makes it possible to stabilize the support state of the basket member 70, and also to stably guide the third attachment member 72C within the passage path PW.

[0066] The second rib 52 also includes a second horizontal rib 52b extending in the width direction. This second horizontal rib 52b can also contribute to guiding the belt-like third attachment member 72C within the passage path PW. That is, when the belt-like third attachment member 72C is moved within the passage path PW, the leading end of the third attachment member 72C comes into contact with the second horizontal rib 52b extending in the width direction, thereby preventing the third attachment member 72C from moving obliquely relative to the passage path PW. That is, the second horizontal rib 52b contacts the leading end of the belt-like third attachment member 72C to adjust the orientation of the third attachment member 72C. More specifically, the orientation of the third attachment member 72C can be adjusted so that the leading end of the third attachment member 72C extends in a direction perpendicular to the longitudinal direction of the passage path PW. As a result, when the basket member 70 is attached or detached using the third attachment member 72C, the second horizontal rib 52b allows the third attachment member 72C to be stably guided within the passage path PW.

[0067] In the illustrated example, as shown in FIG. 4C , the cross member 25 includes a flat portion 25a with a flat outer surface and a curved portion 25b with a curved outer surface in the area covered by the foothold member 40. The tip of the second cross rib 52b faces a connection portion 25c between the flat portion 25a and the curved portion 25b. As can be seen from FIG. 5 , this connection portion 25c extends linearly, particularly in the width direction. In the illustrated example, the tip of the second cross rib 52b faces the connection portion 25c and extends along the connection portion 25c. According to this specific example, the second cross rib 52b is provided in the area where the third attachment member 72C changes direction within the passage path PW. Therefore, when the third attachment member 72C changes direction within the passage path PW during attachment and detachment of the third attachment member 72C to and from the cross member 25, the tip of the third attachment member 72C is more likely to come into contact with the second cross rib 52b. In other words, the second cross rib 52b is provided in an area within the passage path PW where the third attachment member 72C is likely to become clogged, thereby effectively facilitating movement of the third attachment member 72C along the passage path PW.

[0068] As shown in Figure 4C, when viewed from the width direction, multiple second horizontal ribs 52b are provided along the outer surface of the crossover member 25. Furthermore, two connection portions 25c are present within the passage path PW. One second horizontal rib 52b is disposed facing each connection portion 25c. Therefore, the illustrated configuration allows the third attachment member 72C to move more smoothly within the passage path PW.

[0069] As shown in FIG. 7 , the plate-shaped portion 45 includes a pair of side edges 45c located at both ends in the width direction, and a first edge 45a and a second edge 45b extending in the width direction, connecting the pair of side edges 45c. The side edges 45c extend perpendicular to the width direction. As shown in FIGS. 6 and 7 , each of the first longitudinal ribs 51a extends from the first edge 45a to the second edge 45b. As shown in FIG. 5 , the first edge 45a to the second edge 45b are spaced apart from the cross member 25 at the second portion 42 and at least a region including a portion of the first portion 41 adjacent to the second portion 42. In the example shown in FIG. 5 , the first edge 45a and the second edge 45b are spaced apart from the cross member 25 at all ends in the width direction or along their entire lengths. In this way, by forming a gap between the crossover member 25 and the first edge 45a or the second edge 45b of the plate-like portion 45, the user can easily notice the existence of the passageway PW and can easily identify the entrance to the passageway PW. Furthermore, while the stroller 10 is in use, it is possible to prevent a large force that would attempt to peel the foothold member 40 from being applied to the plate-like portion 45 by the third attachment member 72C. Furthermore, it is possible to greatly expand the foothold member 40 from the crossover member 25, making it easier to place a foot on the foothold member 40 in a stable manner.

[0070] 5 and 7, the first edge 45a and the second edge 45b have recesses 47 formed in the second portion 42. These recesses 47 make it easier for the user to notice the passageway PW and to grasp the entrance to the passageway PW. Furthermore, when attaching or detaching the basket member 70, the recesses 47 make it easier to insert the third attachment member 72C into the passageway PW and to pull the third attachment member 72C out of the passageway PW. Furthermore, the recesses 47 can also prevent the third attachment member 72C from exerting a large force on the plate-shaped portion 45 that would peel the foothold member 40 from the crossover member 25 while the stroller 10 is in use.

[0071] In the embodiment described above, the push cart (stroller) 10 has a cart body (stroller body) 15 and a basket member 70 attached to the cart body 15. The cart body 15 has a pair of legs 23 spaced apart in the width direction, wheels 24 held at the lower end portions of each of the pair of legs 23, a cross member 25 extending in the width direction between the pair of legs 23 or the pair of wheels 24, and a footrest member 40 provided on the cross member 25. The basket member 70 has a basket body portion 71 forming a storage section, and a third attachment member 72C extending from the basket body portion 71 and attaching the basket member 70 to the cart body 15.

[0072] According to this embodiment, a passage path PW for the attachment member 72C is formed between the crossover member 25 and the footrest member 40 provided on the crossover member 25. This effectively prevents the attachment member 72C from being positioned on the footrest member 40, allowing a foot to be placed stably on the footrest member 40. This allows a force to be applied stably to the crossover member 25 via the footrest member 40, thereby lifting the wheel 22 held by the leg 21 at the front in the direction of travel. As a result, steps and recesses can be stably overcome. This also effectively prevents the attachment member 72C from becoming soiled by shoes or the like placed on the footrest member 40.

[0073] Although one embodiment has been described with reference to the illustrated specific examples, it is not intended that the embodiment be limited to these specific examples. The above-described one embodiment can be implemented with various other specific examples, and various omissions, substitutions, changes, additions, etc. can be made within the scope of the gist of the embodiment.

[0074] An example of the modification will be described below with reference to the drawings. In the following description and the drawings used in the following description, parts that can be configured similarly to the above-described specific example will be designated by the same reference numerals as those used for the corresponding parts in the above-described specific example, and duplicated descriptions will be omitted.

[0075] The stroller body 15, footrest members 40, and basket member 70 described above are merely examples, and various modifications are possible. Furthermore, in the specific example described above, the footrest members 40 are provided on the crossover member 25 located between the pair of rear legs 23, but this is not limiting. For example, the footrest members 40 may be provided on the crossover member 25 located between the pair of rear wheels 24. Furthermore, as shown in Figure 9, in a stroller 10 with a swingable handle 30, the footrest members 40 may be attached to the crossover member 25 (for example, the front connecting member 26 described above) extending in the width direction between the pair of front legs 21, or to the crossover member 25 extending in the width direction between the pair of front wheels 22.

[0076] Furthermore, as already explained, the cross member 25, footrest member 40 and basket member 70 described above are not limited to application to the stroller 10, but can also be used, for example, in a push cart used as a pet cart for taking pets out, or a push cart used as a dolly for transporting goods.
