Summary of the Invention

Problems to be Solved by the Invention

[0006] Incidentally, in the shopping cart of Patent Document 1 mentioned above, it is conceivable to provide a bag placing portion for placing a bag on the first frame body. In this case, it is conceivable to arrange the bag placing portion between the respective vertical frames on the lower end side of the first frame body and provide it in a state of being connected to each of those vertical frames respectively.

[0007] Here, in a shopping cart, it is required to increase the capacity of the bag so that as many items as possible can be accommodated in the bag. In this case, for example, it is conceivable to increase the capacity of the bag by increasing the dimension of the bag in the front-rear direction.

[0008] However, in the configuration of providing the above-mentioned bag placing portion, when the dimension of the bag in the front-rear direction is increased, accordingly, it is necessary to increase the dimension of the bag placing portion in the front-rear direction. In this case, when the first frame body and the second frame body are in a folded state, there is a possibility that the bag placing portion interferes with the horizontal frame of the second frame body, and it may become impossible to fold each frame body sufficiently. Then, it will lack compactness in the front-rear direction in the folded state, which is not preferable.

[0009] The present invention has been made in view of the above circumstances, and a main object thereof is to provide a shopping cart that can be folded compactly in the front-rear direction while ensuring sufficient capacity of the bag.

Means for Solving the Problem

[0010] In order to solve the above problems, a shopping bag according to a first invention includes a first frame body having a pair of left and right first vertical frame portions with front wheels attached to lower ends thereof, a second frame body having a pair of left and right second vertical frame portions with rear wheels attached to lower ends thereof, a bag placing portion that is respectively connected to lower ends of the first vertical frame portions and is provided to extend in the front-rear direction for placing a bag capable of accommodating purchased items, and a reinforcing frame that connects lower ends of the second vertical frame portions. The first frame body and the second frame body are a shopping cart that can be switched between a deployed state in which the front wheels and the rear wheels are spaced apart front and rear and a folded state in which the front wheels and the rear wheels are close to each other front and rear. The bag placing portion and the reinforcing frame are configured such that when the first frame body and the second frame body are in the folded state, the reinforcing frame enters below the bag placing portion.

[0011] According to the first invention, when the first frame body and the second frame body are in the folded state, the reinforcing frame enters below the bag placing portion. Therefore, even if the front-rear dimension of the bag placing portion is increased, it is possible to avoid interference between the bag placing portion and the reinforcing frame when each frame body is folded. Therefore, the front-rear dimension of the bag can be increased, and as a result, the capacity of the bag can be sufficiently ensured. Further, in the configuration where the reinforcing frame enters below the bag placing portion when each frame body is folded, each frame body can be folded in a compact state in the front-rear direction. Therefore, from the above, it is possible to fold the bag compactly in the front-rear direction while sufficiently ensuring the capacity of the bag.

[0012] The shopping bag of the second invention, in the first invention, the bag placing portion has a rear side portion extending rearward with respect to the first frame body and a front side portion extending forward with respect to the first frame body in a side view. When the first frame body and the second frame body are in the folded state, the reinforcing frame is configured to enter below the rear side portion. The bag placing portion extends downward from the front side portion, and when the first frame body and the second frame body are in the deployed state, it is spaced upward from the ground contact surface of the shopping cart, and when the first frame body and the second frame body are in the folded state, it includes a grounding portion that contacts the ground contact surface.

[0013] According to the second invention, since the bag placing portion extends forward and rearward with respect to the first frame body respectively, it is possible to secure the capacity of the bag while supporting the load of the bag placed on the bag placing portion in a well-balanced manner. Further, a grounding portion extends downward from the front side portion of the bag placing portion, and when the first frame body and the second frame body are in the folded state, the grounding portion contacts the ground contact surface. Thereby, in the configuration where the bag placing portion has a front side portion, the bag can be supported in a stable state when each frame body is folded.

[0014] The shopping bag of the third invention, in the second invention, when the first frame body and the second frame body are in the folded state, the rear wheel is positioned behind the front wheel, and the grounding portion is positioned in front of the front wheel. By placing the rear wheel and the grounding portion on the ground contact surface respectively, the shopping cart stands on its own with the front wheel spaced upward from the ground contact surface.

[0015] According to the third invention, when the first frame body and the second frame body are in the folded state, the rear wheel and the grounding portion are placed on the ground contact surface at positions spaced apart front and rear, so that the shopping cart stands on its own with the front wheel spaced upward from the ground contact surface. Thereby, the bag can be supported in a more stable state when each frame body is folded.

[0016] In the shopping bag according to the fourth invention, in any one of the first to third inventions, the reinforcing frame is bent so that the middle part is positioned forward of both end parts connected to each of the first vertical frame parts, and in the folded state of the first frame body and the second frame body, the middle part of the reinforcing frame enters below the bag placing part.

[0017] According to the fourth invention, since the reinforcing frame is bent so that the middle part is positioned forward of both end parts thereof, it is possible to make it difficult for the legs of a user standing behind the cart to hit the reinforcing frame when the shopping cart is moved. Therefore, it becomes possible to facilitate the movement of the shopping cart. Further, when the first frame body and the second frame body are in the folded state, since the middle part of the reinforcing frame enters below the bag placing part, the above effect can be obtained while ensuring the front - rear compactness in the folded state.

[0018] In the shopping bag according to the fifth invention, in any one of the first to fourth inventions, the first frame body and the second frame body are arranged to intersect each other so as to form a substantially X - shaped in side view, and are rotatably connected at the intersecting portion so as to be switchable between the unfolded state and the folded state, and are provided so as to straddle the first frame body and the second frame body above the intersecting portion, and are arranged above the bag and include a basket placing portion on which a shopping basket can be placed.

[0019] According to the fifth invention, since the basket placement part is provided above the bag, in the store, by placing the shopping basket on the basket placement part, it becomes possible to use the shopping cart as a shopping cart. Further, in the configuration where the basket placement part is provided above the bag, since the height dimension of the bag is restricted by the basket placement part, it is difficult to secure the capacity of the bag by increasing the height dimension of the bag. In this regard, in the fifth invention, since the first invention is applied to such a configuration, it is possible to sufficiently secure the front-rear dimension of the bag, and as a result, it is possible to sufficiently secure the capacity of the bag.

[0020] The shopping bag of the sixth invention is the bag according to any one of the first to fifth inventions, wherein the bag has a bag body for accommodating the purchased items and a pair of left and right wheels attached to the lower end portion of the bag body, the bag body is placed on the bag placing portion, and in the placed state, each wheel is disposed at a position outside the bag placing portion, and when the first frame body and the second frame body are in the folded state, the reinforcing frame enters below the wheel.

[0021] According to the sixth invention, since the bag has wheels, the bag can be taken out of the shopping cart and moved while rolling the wheels. Further, the bag body is placed on the bag placing portion, and in the placed state, each wheel is disposed at a position outside the bag placing portion. Thereby, it becomes possible to support the bag with wheels in a stable state.

[0022] Further, when the first frame body and the second frame body are in the folded state, the reinforcing frame enters below the wheels of the bag at a position outside the bag placing portion. Therefore, even in the configuration of supporting the bag with wheels as described above, it is possible to fold each frame body compactly without interference between the wheels and the reinforcing frame.

[0023] The shopping bag of the seventh invention is the bag according to any one of the first to sixth inventions, and includes the bag placed on the bag placing portion.

[0024] According to the seventh invention, in the shopping cart with a bag, the effects of the first to sixth inventions can be achieved.

Embodiments for Carrying Out the Invention

[0026] Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. FIGS. 1 and 2 are both perspective views of the shopping cart 10 in the deployed state as seen from the front. In FIG. 2, the state where the bag 13 is removed from the shopping cart 10 is shown. FIG. 3 is a side view of the shopping cart 10 in the deployed state, and FIG. 4 is a side view of the shopping cart 10 in the folded state. For convenience, in FIG. 3, the shopping basket K is shown by a two-dot chain line. FIG. 5 is a perspective view of the shopping cart 10 in the deployed state as seen from the rear.

[0027] In the following description, the moving direction when moving the shopping cart 10 is defined as the front-rear direction, and the direction orthogonal to the front-rear direction is defined as the left-right direction. Further, in the following description, unless otherwise specified, the configuration of the shopping cart 10 in the deployed state is referred to.

[0028] As shown in FIGS. 1 to 3, the shopping cart 10 includes a first frame body 11 and a second frame body 12 that constitute the framework of the cart 10, a bag 13 for storing the purchased items (goods), a bag placing portion 14 for placing the bag 13, and a basket placing portion 15 for placing the shopping basket K. According to this shopping cart 10, in a store such as a supermarket, the shopping basket K can be placed on the basket placing portion 15 to be used as a shopping cart. Also, after shopping, the purchased items can be stored in the bag 13 and carried home.

[0029] The first frame body 11 and the second frame body 12 are arranged to intersect each other so as to form a substantially X shape in a side view. The first frame body 11 extends obliquely backward, and the second frame body 12 extends obliquely forward. A front wheel 16 is attached to the lower end portion of the first frame body 11, and a rear wheel 17 is attached to the lower end portion of the second frame body 12. Also, the first frame body 11 extends above the second frame body 12, and a handle 18 for the user to grip when moving the shopping cart 10 is provided on the upper end side of the first frame body 11.

[0030] The first frame body 11 and the second frame body 12 are rotatably connected at an intersection portion 19 where they intersect. These frame bodies 11, 12 can be switched between an unfolded state (the state shown in FIGS. 1 to 3) in which they are unfolded forward and backward and a folded state (the state shown in FIG. 4) in which they are folded forward and backward by the rotation. In the unfolded state of each frame body 11, 12, the front wheel 16 and the rear wheel 17 are separated from each other in the front-rear direction, and in the folded state of each frame body 11, 12, the front wheel 16 and the rear wheel 17 approach each other in the front-rear direction.

[0031] The first frame body 11 has a pair of left and right vertical frame portions 21, a horizontal frame 22 spanned across the middle portions of the respective vertical frame portions 21, and a handle frame 23 spanned across the upper end portions of the respective vertical frame portions 21. Each vertical frame portion 21 has a lower frame 25, an upper frame 26 disposed above the lower frame 25, and a connector 27 connecting the lower frame 25 and the upper frame 26. The lower frame 25 and the upper frame 26 are formed of a metal pipe material or bar material, and the connector 27 is formed of a resin material. A front wheel 16 is attached to the lower end portion of each lower frame 25, and a handle frame 23 is spanned across the upper end portion of each upper frame 26. A handle 18 is constituted by the handle frame 23. Note that the vertical frame portion 21 corresponds to the "first vertical frame portion".

[0032] The second frame body 12 has a pair of left and right vertical frames 31 and a horizontal frame 32 connecting the lower end sides of the respective vertical frames 31. Each vertical frame 31 and the horizontal frame 32 are formed of a metal pipe material or bar material. Each vertical frame 31 intersects the lower frame 25 of the first frame body 11 in an X shape, and a shaft portion 28 extending in the left-right direction is provided at the intersecting portion 19 thereof. The vertical frame 31 and the lower frame 25 are rotatably connected via the shaft portion 28, and thus the first frame body 11 and the second frame body 12 are rotatably connected via the shaft portion 28. Thereby, each of the frame bodies 11, 12 can be switched between the above-described deployed state and folded state by rotation about the shaft portion 28. Note that the vertical frame 31 corresponds to the "second vertical frame portion".

[0033] The horizontal frame 32 extends in the left - right direction, and both of its end portions are respectively connected to each vertical frame 31. The horizontal frame 32 is bent and formed such that the middle portion in its left - right direction is located in front of both end portions in the left - right direction. Specifically, the horizontal frame 32 has a pair of end frame portions 32a that extend forward from the connection end portions connected to each vertical frame 31, and an intermediate frame portion 32b that connects the front end portions of each end frame portion 32a and extends in the left - right direction. Each end frame portion 32a extends while inclining inward in the left - right direction as it goes forward. Also, each end frame portion 32a, and thus the horizontal frame 32, extends while inclining downward as it goes forward in a side view. Note that the horizontal frame 32 corresponds to the "reinforcing frame".

[0034] Subsequently, in addition to FIG. 1, the bag 13 will be described with reference to FIG. 6. FIG. 6 is a perspective view showing the bag 13. Note that in FIG. 6, the front cover 43 is shown in a state of being removed from the bag body 41.

[0035] As shown in FIG. 1, the bag 13 is formed in a substantially rectangular parallelepiped shape with a vertical length and is placed on the bag placing portion 14 in a detachable state. As shown in FIG. 6, the bag 13 has a box - shaped bag body 41, a tray 42 provided inside the bag body 41, and a plurality of covers 43, 44. The bag body 41 is formed with a front - side opening 45 that opens forward and an upper - side opening 46 that opens upward. The front - side opening 45 and the upper - side opening 46 are continuous with each other, and items can be put in and taken out of the bag body 41 through these openings 45, 46.

[0036] A plurality of trays 42 are provided vertically. It is possible to place the purchased items on these trays 42. Also, among the covers 43, 44, there are a front cover 43 that opens and closes the front - side opening 45 and an upper cover 44 that opens and closes the upper - side opening 46. The front cover 43 is detachably attached to the bag body 41 via, for example, a hook - and - loop fastener or the like. Also, the upper cover 44 can be opened backward, for example, by connecting the rear - edge portion to the bag body 41.

[0037] A pair of left and right wheels 48 are attached to the lower end of the bag body 41. Each wheel 48 is arranged at the rear part of the bag body 41. Thereby, it is possible to take out the bag 13 from the bag placing part 14 (and thus the shopping cart 10) and move it while rolling the wheels 48. Therefore, for example, after shopping and returning home, it is possible to take out the bag 13 from the shopping cart 10 at the entrance and carry it to the indoor side.

[0038] A handle 49 for gripping when moving the bag 13 is attached to the back side of the bag body 41. The handle 49 is rotatably attached to the back side of the bag body 41. When the bag 13 is placed on the bag placing part 14, that is, when the bag 13 is attached to the shopping cart 10, the handle 49 is arranged along the back of the bag body 41 (see FIG. 5). On the other hand, when taking out the bag 13 from the shopping cart 10 and moving it, the handle 49 is rotated upward to a state where it stands up above the bag body 41 (see FIG. 6).

[0039] Next, before describing the bag placing part 14, the basket placing part 15 will be described.

[0040] As shown in FIGS. 1 to 3, the basket placing part 15 is provided straddling the frames 11 and 12 above the intersection part 19 where the first frame body 11 and the second frame body 12 intersect. Specifically, the basket placing part 15 is provided straddling the middle part of the first frame body 11 and the upper end part of the second frame body 12. In this case, the basket placing part 15 is arranged above the bag 13.

[0041] The basket placement part 15 is formed in a U-shaped frame shape in plan view. The basket placement part 15 has a pair of left and right arms 51 extending in the front-rear direction and a front-end frame 52 spanned across the front-end parts of the respective arms 51. The rear end side of each arm 51 is rotatably supported by a coupler 27 of the first frame body 11. As a result, the basket placement part 15 can be moved between a placement position (see FIG. 3) where it is placed on the bag 13 and the shopping basket K can be placed, and a retracted position (see FIG. 4) where it is flipped up toward the first frame body 11 side from the placement position by the above-described rotation.

[0042] The front end part of each arm 51 is connected to the upper end part of a vertical frame 31 of the second frame body 12. As a result, when the basket placement part 15 is switched from the placement position to the retracted position, the first frame body 11 and the second frame body 12 are switched from the deployed state to the folded state in conjunction therewith (see FIG. 4). In this case, the shopping cart 10 is in a folded state folded back and forth as a whole. Further, when the basket placement part 15 is switched from the retracted position to the placement position, the respective frame bodies 11 and 12 are switched from the folded state to the deployed state in conjunction therewith. In this case, the shopping cart 10 is in a deployed state deployed back and forth as a whole (see FIG. 3).

[0043] Next, the bag placement part 14 will be described.

[0044] As shown in FIGS. 2 and 3, the bag placement part 14 is composed of a frame body 54 formed in a frame shape by a metal bar. The bag placement part 14 is disposed between the respective vertical frame parts 21 on the lower end side of the first frame body 11 and is connected to the lower end sides of the respective vertical frame parts 21.

[0045] The frame body 54 is formed by bending a rectangular frame formed in a rectangular frame shape by a bar so as to form a substantially Z shape in side view. The frame body 54 is formed having a first part 54a extending in the front-rear direction, a second part 54b extending upward from the rear end part of the first part 54a, and a third part 54c extending downward from the front end part of the first part 54a.

[0046] The bag placing part 14 has a placing part 55 on which the bag 13 is placed, a receiving part 56 that receives the bag 13 from behind, and a grounding part 57. The placing part 55 is constituted by the first part 54a of the frame body 54, the receiving part 56 is constituted by the second part 54b, and the grounding part 57 is constituted by the third part 54c.

[0047] Both sides of the placing part 55 in the left - right direction are respectively connected to the lower - end sides of the respective vertical frame parts 21 (specifically, the lower frame 25) of the first frame body 11. Specifically, the placing part 55 is connected to each vertical frame part 21 via a connecting bar 59 extending left - and - right. Also, the placing part 55 is connected to each vertical frame part 21 at the middle part in the front - rear direction (specifically, approximately the central part). In this case, in side view, the placing part 55 has a rear - side part 55a extending rearward with respect to the vertical frame part 21 and a front - side part 55b extending forward with respect to the vertical frame part 21.

[0048] The bag body 41 of the bag 13 is placed on the placing part 55. In such a placed state, the respective wheels 48 of the bag 13 are respectively arranged on both the left and right sides sandwiching the placing part 55 (see also Fig. 5). Therefore, each wheel 48 is arranged at a position deviated from the placing part 55 and is in a non - placed state with respect to the placing part 55. Also, each wheel 48 is arranged behind the connecting bar 59 and is located at the same position as the rear end part of the placing part 55 in the front - rear direction. Note that each wheel 48 is attached to the bag body 41 in a state of protruding downward from the lower surface of the bag body 41 placed on the placing part 55.

[0049] The bag placing part 14 is arranged in a state inclined rearward. In this case, in side view, the placing part 55 is inclined upward as it goes forward, and the receiving part 56 is inclined rearward as it goes upward. Thereby, the bag 13 is placed on the placing part 55 in a state inclined rearward, and the inclined bag 13 is received from behind by the receiving part 56.

[0050] On the back side of the bag 13, a hook 61 is provided at its upper part. When the bag 13 is placed on the bag placing part 14, the hook 61 is hooked on the horizontal frame 22 of the first frame body 11 (see Fig. 5). Also, the bag 13 is disposed between the vertical frame parts 21 of the first frame body 11.

[0051] The grounding part 57 of the bag placing part 14 extends obliquely forward downward from the front end part of the placing part 55. The lower end part of the grounding part 57 is spaced upward from the ground surface G (floor surface or ground surface), and is disposed in front of the front wheel 16. Also, a stopper part 62 protruding upward from the placing part 55 is fixed to the grounding part 57. By this stopper part 62, the bag 13 is prevented from falling forward.

[0052] Subsequently, the configuration around the bag placing part 14 in the folded state of the shopping cart 10 will be described with reference to Fig. 4.

[0053] As shown in Fig. 4, in the folded state of the shopping cart 10, in other words, in the folded state of the first frame body 11 and the second frame body 12, the grounding part 57 extends vertically downward, and its lower end part contacts the ground surface G. Also, together with this, the front wheel 16 is spaced upward from the ground surface G. Thereby, in the folded state of each frame body 11, 12, the grounding part 57 and the rear wheel 17 are placed on the ground surface G, and the shopping cart 10 is made to stand on its own in that placed state. In this case, in a side view, the rear wheel 17 is located behind the front wheel 16, and the grounding part 57 is located in front of the front wheel 16. Also, in the folded state of each frame body 11, 12, the placing part 55 extends horizontally in the front-rear direction. Therefore, the bag 13 on the placing part 55 is supported in an upright state (that is, a non-inclined state).

[0054] In the folded state of each frame body 11, 12, the horizontal frame 32 of the second frame body 12 enters below the placement part 55 of the bag placing part 14. In this case, the intermediate frame part 32b of the horizontal frame 32 enters at least below the placement part 55. Further, in the state where the horizontal frame 32 has entered below the placement part 55, the rear end part of the horizontal frame 32 is positioned at substantially the same position as the rear end part of the placement part 55 in the front-rear direction.

[0055] In the folded state of each frame body 11, 12, the horizontal frame 32 extends horizontally rearward from the vertical frame 31 in a side view. Therefore, the horizontal frame 32 enters below the placement part 55 in a horizontal orientation. In this case, the horizontal frame 32 and the placement part 55 are arranged parallel to each other in a side view. Further, in the folded state of each frame body 11, 12, the horizontal frame 32 also enters below each wheel 48 of the bag 13 placed on the placement part 55.

[0056] According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

[0057] When the first frame body 11 and the second frame body 12 are in a folded state, since the horizontal frame 32 enters below the bag placing part 14, even if the front-rear dimension of the bag placing part 14 is increased, it is possible to avoid interference between the bag placing part 14 and the horizontal frame 32 when each frame body 11, 12 is folded. Therefore, the front-rear dimension of the bag 13 can be increased, and as a result, the capacity of the bag 13 can be sufficiently ensured. Further, in the configuration where the horizontal frame 32 enters below the bag placing part 14 when each frame body 11, 12 is folded, each frame body 11, 12 can be folded in a compact state in the front-rear direction. Thus, from the above, it is possible to fold compactly in the front-rear direction while sufficiently ensuring the capacity of the bag 13.

[0058] Since the bag placing portion 14 has a rear side portion 55a that extends rearward with respect to the first frame body 11 and a front side portion 55b that extends forward with respect to the first frame body 11 in a side view, it is possible to secure the capacity of the bag 13 while supporting the load of the bag 13 placed on the bag placing portion 14 in a well-balanced manner. Further, a grounding portion 57 extends downward from the front side portion 55b of the bag placing portion 14, and when the first frame body 11 and the second frame body 12 are in a folded state, the grounding portion 57 comes into contact with the ground surface G. Thereby, in the configuration where the bag placing portion 14 has the front side portion 55b, the bag 13 can be supported in a stable state when the respective frame bodies 11, 12 are folded.

[0059] When the first frame body 11 and the second frame body 12 are in a folded state, the rear wheels 17 and the grounding portion 57 are placed on the ground surface G at positions spaced apart front and rear, so that the shopping cart 10 stands independently with the front wheels 16 spaced upward from the ground surface G. Thereby, the bag 13 can be supported in a more stable state when the respective frame bodies 11, 12 are folded.

[0060] Since the horizontal frame 32 is bent and formed such that the middle portion (middle frame portion 32b) is positioned forward of both end portions thereof, it is possible to make it difficult for the legs of a user standing behind the cart to hit the horizontal frame 32 when the shopping cart 10 is moved. Therefore, it becomes possible to facilitate the movement of the shopping cart 10. Further, when the first frame body 11 and the second frame body 12 are in a folded state, the middle frame portion 32b of the horizontal frame 32 enters below the bag placing portion 14, so that the above-described effect can be obtained while ensuring the front-rear compactness in the folded state.

[0061] In the configuration where the basket placement part 15 is provided above the bag 13, since the height dimension of the bag 13 is restricted by the basket placement part 15, it is difficult to secure the capacity of the bag 13 by increasing the height dimension of the bag 13. In this regard, in the above-described embodiment, in such a configuration, the above-described configuration in which the horizontal frame 32 enters below the bag placement part 14 when the respective frame bodies 11 and 12 are folded is applied. Therefore, the front-rear dimension of the bag 13 can be sufficiently secured, and as a result, the capacity of the bag 13 can be sufficiently secured.

[0062] The bag body 41 of the bag 13 is placed on the bag placement part 14, and in the placed state, the respective wheels 48 of the bag 13 are arranged at positions deviated from the bag placement part 14. Thereby, it becomes possible to support the bag 13 with wheels in a stable state.

[0063] Further, when the first frame body 11 and the second frame body 12 are in the folded state, the horizontal frame 32 enters below the wheels 48 of the bag 13 located at positions deviated from the bag placement part 14. Therefore, even in the configuration of supporting the bag 13 with wheels as described above, the respective frame bodies 11 and 12 can be folded compactly without interference between the wheels 48 and the horizontal frame 32.

[0064] The present invention is not limited to the above-described embodiment, and may be implemented, for example, as follows.

[0065] · A configuration may be adopted in which the grounding part 57 is not provided. In this case, when the respective frame bodies 11 and 12 are in the folded state, the shopping cart 10 may be made to stand on its own by grounding the front wheels 16 and the rear wheels 17 on the ground surface G at positions separated from each other in the front-rear direction.

[0066] · In the above-described embodiment, the bag placement part 14 is formed in a frame shape, but the bag placement part 14 may be formed in a plate shape.

[0067] · The bag 13 does not necessarily have to have wheels and may not have wheels. Also, the bag 13 does not necessarily have to be detachable from the bag mounting portion 14, and for example, the bag 13 may be fixed to the bag mounting portion 14 and provided in a non-detachable manner.

[0068] · In the above embodiment, the basket mounting portion 15 moves between the mountable position and the retracted position, and the frame bodies 11 and 12 are switched between the deployed state and the folded state in conjunction with this movement. However, the movement of the basket mounting portion 15 and the state switching of the frame bodies 11 and 12 do not necessarily have to be interlocked, and they may be configured to be performed independently of each other.

[0069] · The horizontal frame 32 may be formed linearly across the entire width in the left-right direction. Even in this case, by allowing the horizontal frame 32 to enter below the bag mounting portion 14, the same effects as in the above embodiment can be obtained.

[0070] · In the above embodiment, the present invention is applied to the shopping cart 10 provided with the basket mounting portion 15, but the present invention may also be applied to a shopping cart not provided with the basket mounting portion 15.

[0071] · In the above embodiment, the present invention is applied to the shopping cart 10 with a bag provided with the bag 13, but the present invention may also be applied to a shopping cart not provided with a bag. In that case, a bag is prepared separately from the shopping cart, and the prepared bag is placed on the bag mounting portion 14 of the shopping cart for use.
