DETAILED DESCRIPTION OF THE INVENTION

[0013] Next, the cover and the carriage according to the present invention will be described below by way of preferred embodiments with reference to the accompanying drawings. Note that the embodiments and drawings described below are intended to exemplify some of the embodiments of the present invention, and are not intended to limit the scope of the present invention to these configurations, and can be modified as appropriate within the scope of the gist of the present invention.

[0014] 1 to 4 show a dolly 50 to which a cover 10 according to this embodiment is attached. The dolly 50 is an article transport device suitable for use in transporting articles such as food to stores such as supermarkets and convenience stores, and is exemplified as a basket dolly. The dolly 50 includes a rear frame 52, left and right cross frames 54, 54 connected to the rear frame 52, a base 56 whose rear edge is hingedly connected to the lower edge of the rear frame 52, and a shelf 58 disposed above the base 56. In this way, the dolly 50 of this embodiment is capable of loading articles not only on the base 56 but also on the shelf 58. The dolly 50 includes casters 51 on its bottom.

[0015] As shown in Figures 2 and 4, the rear frame 52 is configured in a fence-like shape by combining metal rod-shaped bodies. The rear frame 52 has a rear surface portion 52a that forms the rear surface of the carriage 50, a side surface portion 52b that forms the rear side portion of the carriage 50, and a support portion 60 for supporting a shelf 58. The support portion 60 is formed in a groove shape that opens inward (see Figure 7). The support portion 60 has a horizontal support portion 60a that is arranged to bridge between the rod-shaped bodies that form the side surface portion 52b, and a vertical support portion 60b that extends downward from the rear end of the horizontal support portion 60a, and is formed in an "L" shape in side view (see Figures 5 and 6).

[0016] 1 and 3, the horizontal frame 54 is configured in a fence-like shape by combining metal rods. The horizontal frame 54 is hingedly connected to the front edge of the side portion 52b of the rear frame 52. The dolly 50 is used with the base portion 56 spanning the horizontal frames 54, 54 arranged opposite each other.

[0017] As shown in Fig. 5, shelf 58 has a connecting portion 62 provided on the rear side of shelf 58 and supported by a support portion 60 of rear frame 52, which is the main body side of dolly 50, and a hooking portion 64 provided on the front side of shelf 58 and supported by a front receiving portion 54a provided on the front portion of horizontal frame 54. Shelf 58 in this embodiment has two connecting portions 62, 62 arranged spaced apart in the front and rear, and shelf 58 is connected to side portion 52b of rear frame 52 by connecting portion 62. Shelf 58 is placed in a horizontal position where an article can be placed by arranging the two connecting portions 62, 62 on horizontal receiving portion 60a of support portion 60 and hooking hooking portion 64 onto front receiving portion 54a (see dotted line in Fig. 5). After removing the hooking portion 64 from the front support portion 54a, the shelf 58 rotates upward and positions the two connecting portions 62, 62 in the vertical support portion 60b of the support portion 60, thereby assuming a retracted position in which the shelf 58 is upright along the rear surface portion 52a of the rear frame 52 (see the dotted line in Figure 5).

[0018] When the dolly 50 according to this embodiment is not in use, the shelf 58 and base 56 can be raised so as to overlap the front side of the rear surface 52a of the rear frame 52, and the pair of horizontal frames 54, 54 can be folded using hinges at the rear edges as fulcrums so as to overlap the front sides of the rear surface 52a, shelf 58, and base 56. By nesting the folded dollies 50 so that they are placed one on top of the other, it is possible to store multiple dollies 50 while minimizing storage space.

[0019] The cover 10 shown in Figures 1 and 2 is for transporting goods, such as food, to a store such as a supermarket or convenience store. The cover 10 can be attached to the inside of a cart 50 having a shelf 58 without removing the shelf 58 (see Figure 6). The cover 10 of this embodiment is particularly suitable for attachment to a cart 50 for transport, which is called a basket cart, and which has three sides except for the front opening surrounded by a fence-like frame. The cover 10 is configured to have functions such as temperature control, dustproofing, and light-blocking, depending on the goods to be stored inside, such as keeping things cold or warm, and in this embodiment, a cold-keeping cover capable of maintaining a temperature suitable for storing food is exemplified.

[0020] As shown in FIGS. 8 to 11 , the cover 10 of this embodiment is formed into a rectangular parallelepiped shape by sewing or joining flexible, insulating sheets. The cover 10 includes a rear wall 12 that forms the back surface of the cover 10, left and right side walls 14, 14, each of whose rear edges is connected to the side edges of the rear wall 12 and that form the sides of the cover 10, and a bottom wall 16 that is connected to the lower edge of the rear wall 12 and the lower edges of the side walls and forms the bottom surface of the cover 10. The cover 10 also includes an opening / closing section 18 that is connected to the upper edge of the rear wall 12, and the opening / closing section 18 forms the top and front surfaces of the cover 10. The opening / closing section 18 is detachably attached to the upper and front edges of the side walls 14 by fasteners 20 such as zippers. By separating the opening / closing section 18 using the fasteners 20, the lower end of the opening / closing section 18 can be lifted upward around the upper end of the opening / closing section 18, opening the front surface of the cover 10 and providing an entrance / exit for items. Reference numeral 22 denotes a belt for attachment to a dolly 50. The belt 22 is wound around the rod-shaped members that make up the rear frame 52 and the side frames 54 of the carriage 50, and then fixed with a detachable fastener such as a hook-and-loop fastener provided on the belt 22.

[0021] As shown in Figures 9 and 12, the cover 10 is provided with a first opening 24 formed across the left and right sides of the rear wall 12, through which the shelf 58 of the cart 50 can be inserted, and second openings 26 formed in each of the left and right side walls 14, 14, connected to the first opening 24, through which a connecting portion connecting the shelf 58 to the main body of the cart 50 can be inserted. Also, as shown in Figures 7, 8 and 12, the cover 10 is provided with an inner covering portion 28 that covers the first opening 24 from the inside. Furthermore, as shown in Figures 1 to 3 and 8 to 10, the cover 10 is provided with an outer covering portion 30 that covers the second opening 26 from the outside.

[0022] As shown in Fig. 12, the first opening 24 is formed in the rear wall 12 at a position that aligns with the vertical position of the shelf 58. The first opening 24 is formed in a portion of the rear wall 12 in the vertical direction, from the right end to the left end of the rear wall 12, and is configured to allow the shelf 58, which is in a horizontal position, to be inserted from the front to the rear. In this embodiment, the first opening 24 is formed in a slit shape in which the upper and lower opening edges of the first opening 24 abut against each other. The first opening 24 expands vertically to allow the shelf 58 to be inserted therethrough, and after the shelf 58 has been inserted, the upper and lower opening edges of the first opening 24 abut against each other to close.

[0023] As shown in FIGS. 5, 9, and 10, the second opening 26 is formed in the rear of the side wall 14 and is connected to the first opening 24. The second opening 26 is formed in a partial range in the front-rear direction extending from the rear end of the side wall 14 to the front. The second opening 26 is also formed in a partial range in the up-down direction of the side wall 14, and the opening dimension in the up-down direction of the second opening 26 is set to be larger than the opening dimension in the up-down direction of the first opening 24. The second opening 26 in this embodiment is formed to fit the support portion 60 of the bogie 50. In this embodiment, the opening dimension in the front-rear direction of the second opening 26 is set to be equal to or larger than the dimension of the support portion 60 in the front-rear direction, and the opening dimension in the up-down direction of the second opening 26 is set to be equal to or larger than the dimension of the support portion 60 in the up-down direction. In this way, by forming the second opening 26 to match the size of the horizontal support portion 60a and the vertical support portion 60b in the support portion 60, it is possible to prevent the connecting portion 62 from getting caught on the side wall 14 when the shelf 58 is moved between the horizontal position and the retracted position, and the position of the shelf 58 can be changed smoothly even when the cover 10 is attached to the cart 50.

[0024] As shown in FIGS. 7 and 12 , the inner covering portion 28 is disposed inside the rear wall 12. The inner covering portion 28 is in the form of a flap, the upper end of which is connected to the rear wall 12 above the first opening 24 by sewing or the like. The lower end of the inner covering portion 28 is detachably held by an inner holding portion 32 provided below the first opening 24. The inner holding portion 32 in this embodiment is a hook-and-loop fastener, and a hook-and-loop fastener that adheres to the inner holding portion 32 is provided at the lower end of the inner covering portion 28. The left-to-right dimension of the inner covering portion 28 may be set to match the left-to-right dimension of the rear wall 12, but the inner covering portion 28 in this embodiment is formed slightly smaller than the left-to-right dimension of the rear wall 12. When the inner covering portion 28 in this embodiment is attached to the inner holding portion 32 so as to straddle the first opening 24 from top to bottom, it covers most of the first opening 24 and holds the first opening 24 so as not to open up or down.

[0025] 9 and 10, the outer covering part 30 is disposed on the outside of the side wall 14. The outer covering part 30 has a first flap 30a whose front end is fixed to the side wall 14 and whose rear end is detachable from the rear wall 12, and second flaps 30b which extend from the upper and lower ends of the first flap 30a and whose tip ends are detachable from the side wall 14. The outer covering part 30 is formed in a cross shape in a side view.

[0026] As shown in FIGS. 9 and 10 , the front end of the first flap 30a is connected to the front side of the second opening 26 in the side wall 14 by sewing or the like, and the rear end of the first flap 30a is detachably held by a rear holding part 34 provided on the outside of the rear wall 12. The rear holding part 34 is disposed on the rear side of the second opening 26. In this embodiment, the rear holding part 34 is a hook-and-loop fastener, and the hook-and-loop fastener that adheres to the rear holding part 34 is provided at the rear end of the first flap 30a. The front-to-rear dimension of the first flap 30a is set to be larger than the front-to-rear dimension of the second opening, and the up-to-down dimension of the first flap 30a is set to be equal to or larger than the up-to-down dimension of the second opening 26. In this embodiment, the first flap 30a is configured to cover the second opening 26 when attached to the rear holding part 34 across the second opening 26 from front to back.

[0027] 9 and 10 , the second flaps 30b include those that extend upward from the upper edge of the first flap 30a and those that extend downward from the lower edge of the first flap 30a, and both are formed at positions corresponding to the second opening 26. The tip of the upper second flap 30b is detachably held by a lateral holding portion 36 provided above the second opening 26 in the side wall 14. The tip of the lower second flap 30b is detachably held by a lateral holding portion 36 provided below the second opening 26 in the side wall 14. The lateral holding portion 36 in this embodiment is a hook-and-loop fastener, and a hook-and-loop fastener that adheres to the lateral holding portion 36 is provided at the tip of the second flap 30b. The front-to-rear dimension of the second flap 30b is preferably set to be larger than the front-to-rear dimension of the second opening, and the up-to-down dimension of the second flap 30b is set to a dimension that can fill the gap between the side wall 14 and the first flap 30a, which is spaced apart by the side surface portion 52b of the rear frame 52. In this embodiment, the upper second flap 30b is attached to the lateral holding portion 36 to cover the gap between the first flap 30a and the upper side of the second opening 26, and the lower second flap 30b is attached to the lateral holding portion 36 to cover the gap between the first flap 30a and the lower side of the second opening 26.

[0028] As shown in FIGS. 8 to 10 , a bag-shaped portion 38 capable of receiving a hooking portion 64 provided on the front portion of a shelf 58 is formed in the front portion of the side wall 14. The bag-shaped portion 38 is provided at a position corresponding to the front receiving portion 54a of the horizontal frame 54. The bag-shaped portion 38 is formed of a sheet material that is more flexible than the side wall 14. The shelf 58 is supported at its front side by the horizontal frame 54 by inserting the hooking portion 64 into the bag-shaped portion 38 from the inside and hooking the hooking portion 64 together with the bag-shaped portion 38 onto the front receiving portion 54a from the inside of the bag-shaped portion 38 (see FIG. 5 ). In this way, the side wall 14 can be attached to the horizontal frame 54 via the bag-shaped portion 38 without providing a hole for the hooking portion 64 to pass through.

[0029] The installation of the cover 10 according to this embodiment onto the dolly 50 will now be described. The hooking portions 64 of the shelf 58 are removed from the front receiving portions 54a of the horizontal frame 54. The inner covering portion 28 is also removed from the inner holding portion 32. The shelf 58, which is in a horizontal position, is passed through the first opening 24, which has been widened vertically, and the cover 10 is pushed from the front to the rear of the dolly 50. As the cover 10 is pushed into the dolly 50, the connecting portions 62 protruding laterally from the side surfaces of the shelf 58 pass through the second opening 26. With the connecting portions 62 supported by the horizontal receiving portions 60a of the support portions 60, the rear wall 12 of the cover 10 can be positioned along the rear surface portion 52a of the rear frame 52, and the side walls 14 of the cover 10 can be positioned along the side surface portions 52b of the rear frame 52 and the horizontal frame 54. The belt 22 is attached to the rear frame 52 and the horizontal frames 54, and the cover 10 is shaped to fit the rear frame 52 and the horizontal frames 54. The inner covering portion 28 is passed from top to bottom through the gap between the shelf 58 and the rear wall 12 and attached to the inner holding portion 32, thereby covering the first opening 24 from the inside with the inner covering portion 28. The outer covering portion 30 is pulled outward from between the rod-shaped members constituting the side portions 52b of the rear frame 52 and the rod-shaped members at the rear of the horizontal frames 54, and the first flap 30a is wrapped around it from front to back and attached to the rear holding portion 34. The second flap 30b is also pushed between the rod-shaped members constituting the side portions 52b of the rear frame 52 and attached to the horizontal holding portion 36. This causes the second opening 26 to be covered from the outside with the outer covering portion 30. By hooking the hooking portion 64 of the shelf 58 together with the bag-shaped portion 38 onto the front receiving portion 54a, the front portion of the shelf 58 is attached to the horizontal frame 54, and an item can be placed on the shelf 58. To remove the cover 10, simply follow the steps described above in reverse.

[0030] The cover 10 according to this embodiment includes a first opening 24 formed across the left and right sides of the rear wall 12 and through which a shelf 58 can be inserted, and second openings 26 formed in the left and right side walls 14 and connected to the first opening 24 and through which a connecting portion 62 of the shelf 58 can be inserted. The cover 10 not only allows the shelf 58 to pass through the first opening 24, but also allows the connecting portion 62, which remains connected to the support portion 60, to pass through the second opening 26. This allows the cover 10 to be attached even when the shelf 58 is attached to the cart 50. Similarly, the cover 10 can be removed even when the shelf 58 is attached to the cart 50. Because the shelf 58 does not need to be removed from the cart 50 when attaching or detaching the cover 10 to or from the cart 50, the cover 10 is easy to attach and detach even when the cover 10 has a shelf 58, reducing the effort and time required to attach and detach the cover 10 to and from the cart 50. At a site where the cart 50 is used, work of attaching and detaching covers 10 to a large number of carts 50 occurs, and therefore improving the efficiency of attaching and detaching covers 10 per cart 50 brings about a significant overall benefit. As described above, the cart 50 according to the present embodiment is provided with a cover 10 that is easy to attach and detach even when it has a shelf 58, thereby improving the efficiency of attaching and detaching covers 10. Moreover, the cover 10 is provided with an inner covering portion 28 that covers the first opening 24 from the inside, and therefore it is possible to minimize the deterioration of functions such as temperature control, dust prevention, and light blocking that occur when the first opening 24 is formed in the rear wall 12.

[0031] The cover 10 includes an outer covering 30 that covers the second opening 26 from the outside, thereby minimizing the degradation of functions such as temperature control, dustproofing, and light blocking that would otherwise occur due to the formation of the second opening 26 in the side wall 14. The outer covering 30 also includes a first flap 30a whose front end is fixed to the side wall 14 and whose rear end is detachably attached to the rear wall 12, and second flaps 30b that extend from the upper and lower ends of the first flap 30a and whose leading ends are detachably attached to the side wall 14. According to the outer covering 30 of this embodiment, not only can the first flap 30a cover the outside of the second opening 26, but the second flap 30b can also cover the gap between the first flap 30a and the side wall 14. This improves the sealing of the second opening 26 by the outer covering 30.

[0032] (Example of change) The present invention is not limited to the above-mentioned matters, but may be, for example, as follows: Note that the present invention is not limited to the specific descriptions of the embodiment and the following modified examples. (1) As in the embodiment described above, the outer covering part 30 is not limited to being attached at a position away from the first opening 24. As in another embodiment shown in Fig. 13, the outer covering part 30 may cover at least a portion of the first opening 24 from the outside. In this case, it is preferable that the outer covering part 30 covers the side edge of the first opening 24 that is not covered by the inner covering part 28, and it is even more preferable that the inner covering part 28 and the outer covering part 30 partially overlap to cover the first opening. (2) In the embodiment, the first opening is in the form of a slit, but is not limited to this. The first opening may be in the form of a narrow slit in which the distance between the upper and lower opening edges is smaller than the vertical dimension (thickness) of the shelf, or the first opening may be in the form of a narrow hole in which the distance between the upper and lower opening edges is equal to or greater than the vertical dimension (thickness) of the shelf. (3) In the above-described embodiment, the hook-and-loop fastener is used as an example of a means for fastening and unfastening. Snap buttons or other means may also be used.
