[0024] Hereinafter, an embodiment of a shelf board and a cart equipped with the shelf board of the present invention will be described with reference to the drawings. The cart of the present invention can move between the back yard of a store and the sales floor of the store, and is used as a shelf for stocking merchandise in the back yard and as a means of transport for transporting merchandise from the back yard to the display shelves in the sales floor. [First embodiment]

[0025] As shown in Figures 1 to 3, the trolley 11 comprises a car body 12 arranged along the floor (ground), a first fence 13 standing up from the car body 12, a second fence 14 standing up from the car body 12 and spaced apart from the first fence 13, and a shelf board 15 spanning between the first fence 13 and the second fence 14.

[0026] The vehicle body 12 has a bottom plate portion 21 and a plurality of wheels 22 rotatably provided on the underside of the bottom plate portion 21. As shown in Fig. 2, the wheels 22 are not only rotatable around a rotation axis along the traveling direction, but may also be configured to be rotatable 360° in the horizontal direction around a support shaft 22A at that position. The bottom plate portion 21 may be formed of, for example, a synthetic resin material.

[0027] The first fence 13 is provided, for example, at the front end of the vehicle body 12. The first fence 13 has a pair of first vertical members 23 standing up from corners of the bottom plate portion 21, a first horizontal member 24 connecting approximately the tip ends of the pair of first vertical members 23, and a first intermediate horizontal member 25 connecting the pair of first vertical members 23 at intermediate positions. The tip end (upper end) of the first vertical member 23 is located at a height approximately equivalent to waist height of an adult. Here, the approximately tip end refers to the tip end of the first vertical member 23 or a portion near the tip end.

[0028] The second fence 14 is provided, for example, at the rear end of the vehicle body 12. The second fence 14 has a pair of second vertical members 26 standing up from the corners of the bottom plate portion 21, a second horizontal member 27 connecting the approximate tip ends of the pair of second vertical members 26, and a second intermediate horizontal member 28 connecting the intermediate positions of the pair of second vertical members 26. The tip end (upper end) of the second vertical member 26 is located at a height approximately equivalent to the waist height of an adult. Here, the approximate tip end refers to the tip end of the second vertical member 26 or a portion near the tip end. The diameter of the first horizontal member 24 is the same as the diameters of the first intermediate horizontal member 25, the second horizontal member 27, and the second intermediate horizontal member 28.

[0029] The shelf board 15 is, for example, detachably stretched between the first horizontal member 24 of the first fence 13 and the second horizontal member 27 of the second fence 14. Alternatively, the shelf board 15 may be detachably stretched between the first intermediate horizontal member 25 of the first fence 13 and the second intermediate horizontal member 28 of the second fence 14. The shelf board 15 is installed so as to be stretched between horizontal members of the same height between the first fence 13 and the second fence 14 so as to be disposed substantially horizontally. A plurality of shelves 15 may be installed for one cart 11 so that shelves are formed in a plurality of tiers on one cart 11.

[0030] As shown in Figures 4 and 8, shelf board 15 is formed into a rectangular shape when viewed from above. As shown in Figures 4 to 7, shelf board 15 includes a flat shelf board main body 31, a cover 32 attached to shelf board main body 31, and a fixing member 33 that fixes shelf board main body 31 and cover 32. Fixing member 33 is formed of, for example, a screw, but may be formed of a fixing means other than a screw, such as a rivet.

[0031] The shelf board body 31 has a long side portion 34, a short side portion 35 extending in a direction intersecting the long side portion 34, a recess 36 recessed inward from the short side portion 35, a through hole 37 provided near the recess 36, and a short side and one or more beams 38 extending in a direction intersecting with the short side 35. The short side 35 is an example of a side. In this embodiment, the recess 36 is recessed from the short side 35, but the position at which the recess 36 is provided is not limited thereto, and the recess 36 may be recessed from the long side 34. In that case, the cover 32 is provided so as to cover the long side 34. The shelf body 31 is preferably formed of, for example, a metal material (for example, iron or aluminum alloy). The portion of the shelf body 31 other than the beams 38 is, for example, made of flat sheet metal. The recess 36 and the handle 43 are preferably provided at a position away from the one or more beams 38 in the direction in which the short side 35 extends.

[0032] As shown in FIG. 7, one or more beams 38 are formed to have a rectangular cross section. Each of the beams 38 may be formed to have a rectangular cross section by welding a metal sheet bent into a convex shape to a flat metal sheet, or may be formed by bending a flat metal sheet into a substantially rectangular cross section by pressing. One or more beams 38 are provided across the entire width of the shelf board 15 in the longitudinal direction. In a modified example, one of the beams 38 may be provided to extend in a direction intersecting with the short side portion 35 at a position corresponding to the handhold 43, in which case both ends of the beam 38 may be integrated with the handhold 43.

[0033] As shown in Figs. 4 to 8, the cover 32 has a cover body 42 having a first portion 42A and a second portion 42B that cover the short side portion 35, a handle portion 43 that covers the recess 36, a second handle portion 44 that is provided to face the handle portion 43 and connects the first portion 42A and the second portion 42B, a hole portion 45 that is provided between the handle portion 43 and the second handle portion 44 and through which a hand is passed, and a hook portion 46 that is provided to protrude downward from the back side of the cover body 42. The cover 32 is preferably integrally molded from a synthetic resin material, for example. The hole portion 45 is formed in an elliptical shape that is elongated in the direction along the short side portion 35. The hook portion 46 is formed in an "L"-shaped cross section. The shelf board 15 can be hung from the first fence 13 or the second fence 14 in an upright position with its longitudinal direction aligned vertically (vertical) by hooking the hook portion 46 onto the first horizontal member 24 of the first fence 13 or the second horizontal member 27 of the second fence 14, etc.

[0034] As shown in Figs. 6 and 7, each of the first part 42A and the second part 42B of the cover body 42 has a bag-like shape into which the short side part 35 can be inserted and held. In other words, each of the first part 42A and the second part 42B has a bottomed frame shape with an opening on the shelf body 31 side. The first part 42A corresponds to one corner of the shelf 15, and the second part 42B corresponds to a corner of the shelf 15 different from the one corner. The second part 42B is provided separately from the first part 42A and is provided on the opposite side of the first part 42A with the handle part 43 interposed therebetween. The second part 42B is connected to the first part 42A via the handle part 43 and the second handle part 44.

[0035] As shown in Figures 6, 7 and 10, each of the first portion 42A and the second portion 42B includes a first abutment piece 47 abutting against the front side of the short side portion 35, a third abutment piece 51 abutting against the back side of one or more beam portions 38, a short wall portion 52 connecting the first abutment piece 47 and the third abutment piece 51 and extending along the short side portion 35, a substantially trapezoidal side wall portion 53 connecting the first abutment piece 47 and the third abutment piece 51 and extending along the long side portion 34, and a second through hole formed in the first abutment piece 47. The third abutment piece 51 has a boss portion 55 provided at a position facing the second through hole 54, a claw portion 56 protruding downward from the short wall portion 52, a receiving portion 57 into which the claw portion 56 extending from another shelf board 15 is inserted, a protruding piece 58 protruding downward from the underside of the third abutment piece 51, and a recess 61 (see FIG. 12) into which the horizontal members (first horizontal member 24, first intermediate horizontal member 25, second horizontal member 27, second intermediate horizontal member 28) of the first fence 13 and the second fence 14 are fitted. The recess 61 is provided in the vicinity of the hole 45.

[0036] As shown in FIG. 10, the tip of the first contact piece 47 is positioned outside the tip of the third contact piece 51. It is preferable that the first abutment piece 47 is positioned so that the tip of the first abutment piece 47 has a first chamfered portion 47A that is inclined upward as it approaches the inside of the shelf board 15. The shelf board main body 31 can be sandwiched and held between the first abutment piece 47 and the third abutment piece 51. As a modified example, the third abutment piece 51 may be formed in a positional relationship such that the tip of the third abutment piece 51 overlaps the tip of the first abutment piece 47 when viewed from above.

[0037] 6, the boss portion 55 is provided so as to protrude from the third contact piece 51 toward the first contact piece 47. A gap is provided between the boss portion 55 and the first contact piece 47, and the short side portion 35 of the shelf board main body 31 can be inserted into this gap.

[0038] As shown in FIG. 12, the recess 61 is provided between the claw portion 56 and the protruding piece 58 .

[0039] As shown in FIG. 8, the handle portion 43 has a gentle arc shape that is convex inward when viewed from above. As shown in FIG. 9 and FIG. 11, the handle portion 43 has an arc-shaped cross section that is convex outward. In other words, the handle portion 43 has a cross section that is approximately "C" shaped and opens inward. The handle portion 43 has a step portion 62 in which the recess 36 is housed, a top portion 63 provided adjacent to the step portion 62, a bottom portion 64 provided on the opposite side of the top portion 63, and a second abutment piece 65 that forms the bottom surface of the step portion 62 and extends inward. The top portion 63 is flush with the surface 31A of the shelf board main body 31. The top portion 63 has a first arc portion 63A that is processed into an arc shape so as to be convex toward the front side and the outside. As shown in FIG. 9, FIG. 10, etc., the top portion 63 is continuous with the first abutment piece 47.

[0040] As shown in Figs. 6, 7, 9, and 10, the bottom 64 is formed so as to be continuous with the third abutment piece 51 of the cover body 42 (the first portion 42A and the second portion 42B). The bottom 64 has a second arcuate portion 64A that is processed into an arcuate shape so as to be convex toward the back side and the outside. Here, the "arcuate cross section that is convex toward the outside" in the present invention can take various forms, and may have a flat surface between the top 63 and the bottom 64 as in this embodiment. In addition, the "arcuate cross section that is convex toward the outside" may have only the top 63 having the first arcuate portion 63A in the handgrip 43, or may have only the bottom 64 having the second arcuate portion 64A in the handgrip 43, or the handgrip 43 may have a cross section that is part or all of an ellipse. Alternatively, the "arcuate cross section that is convex toward the outside" may include a recess for hanging a finger between the top 63 and the bottom 64.

[0041] The second contact piece 65 comes into contact with the rear side of the recess 36. The second contact piece 65 has a second chamfered portion 65A at its tip that is inclined downward as it approaches the inside of the shelf board 15.

[0042] As shown in Figures 4, 5 and 9, the second handhold portion 44 is provided outside the handhold portion 43 and generally parallel to the handhold portion 43. The second handhold portion 44 has a third arc portion 44A at its upper portion, which is processed into an arc shape so as to be convex upward. The second handhold portion 44 has a flat abutment surface 44B at its lower portion, which abuts against either the first horizontal member 24 or the second horizontal member 27. The second handhold portion 44 is positioned above the horizontal members (first horizontal member 24, first intermediate horizontal member 25, second horizontal member 27, second intermediate horizontal member 28) of the first fence 13 and the second fence 14 when the shelf board 15 is placed between them. As shown in FIG. 12, the diameter D1 of the second handrail portion 44 is configured to be larger than the diameter D2 of the cross members (first cross member 24, first intermediate cross member 25, second cross member 27, second intermediate cross member 28) of the first fence 13 and the second fence 14.

[0043] Next, a process for assembling the shelf board 15 of this embodiment will be described with reference to Figures 4 to 11. The shelf board 15 is formed integrally by attaching the cover 32 to the short side portion 35 of the shelf board main body 31.

[0044] 6 and 7, the cover 32 is aligned with the shelf body 31 and inserted into the shelf body 31 so that the handle portion 43 is inserted into the recess 36. At this time, the short side portion 35 of the shelf body 31 is inserted into the bag-shaped first portion 42A and second portion 42B of the cover 32.

[0045] As shown in FIG. 10, the first abutment piece 47 of the cover body 42 (first portion 42A, second portion 42B) abuts against the front side of the short side portion 35. The third abutment piece 51 of the cover body 42 abuts against the back side of the short side portion 35. The second abutment piece 65 of the handle portion 43 abuts against the back side of the recess 36. At this time, since the first chamfered portion 47A is provided at the tip of the first abutment piece 47, the short side portion 35 is smoothly guided to the inside of the cover body 42 when the short side portion 35 is inserted. Similarly, as shown in FIG. 9, since the second chamfered portion 65A is provided at the tip of the second abutment piece 65, the recess 36 is smoothly guided to the outside of the second abutment piece 65 when the recess 36 is inserted.

[0046] In this way, the front side of the short side portion 35 is held by the first abutment piece 47, and the back side of the recess 36 is held by the second abutment piece 65. This makes the shape of the shelf board main body 31 stable, and even when a heavy product is placed on the shelf board main body 31, bending, sinking, etc. are prevented as much as possible.

[0047] With the short side portion 35 inserted into the cover body 42, the fixing member 33 is passed through the second through hole 54 of the cover 32 and the through hole 37 of the shelf body 31, and the fixing member 33 is fastened to the boss portion 55 to integrate the shelf body 31 and the cover 32. This completes the assembly process of the shelf 15.

[0048] Next, the operation of the shelf board 15 of this embodiment and the cart 11 equipped with this shelf board 15 will be described with reference to FIG. 13 and the like. The shelf board 15 of this embodiment is provided with a recess 36 (hole 45) and a handhold 43 into which a hand can be inserted. Therefore, as shown in FIG. 1 and FIG. 13, a worker can lift the shelf board 15 from a position between the first fence 13 and the second fence 14 by inserting one hand into one recess 36 (hole 45) and inserting the other hand into the other recess 36 (hole 45). Therefore, even when the shelf board 15 is installed so as to span between the first fence 13 and the second fence 14, or when the installation height of the shelf board 15 already installed between the first fence 13 and the second fence 14 is changed, the worker can lift the shelf board 15 from a position between the first fence 13 and the second fence 14 and can easily move the shelf board 15. Furthermore, because the handle portion 43 has an arc-shaped cross section that protrudes outward, the recessed portion 36 does not dig into the worker's hand, making it easy for the worker to hold the shelf board 15.

[0049] As shown in FIG. 1, the dolly 11 does not have a handle. In addition, when the shelf board 15 is stretched between the first horizontal member 23 and the second horizontal member 27, the second handhold 44 is integrated with either the first horizontal member 24 or the second horizontal member 27 via the abutment surface 44B. Therefore, an operator can push the dolly 11 from the rear side or pull the dolly 11 from the front side by inserting his / her hand into the recess 36 (hole 45) of the shelf board 15 or by gripping the second handhold 44. Therefore, there is no need to provide the dolly 11 with a handle as a handle portion, and the first fence 13 and the second fence 14 can be common parts. This reduces the manufacturing cost of the dolly 11. In addition, since the dolly 11 of this embodiment does not have a handle, as shown in FIG. 1, by stretching the shelf board 15 between the first horizontal member 24 and the second horizontal member 27, products larger than the shelf board 15 can also be placed on the shelf board 15. In particular, in this case, as shown in FIG. 2, the tip of the first vertical member 23 and the tip of the second vertical member 26 are flush with the first abutting piece 47 of the cover 32 of the shelf board 15, so that when a worker places a product on the shelf board 15, the worker may accidentally catch the product or his / her hand on the first vertical member 23 and the second vertical member 26. Therefore, it can handle large products and is easy for workers to use.

[0050] Also, as shown in Fig. 14, the worker can hang the shelf board 15 with one hand. In this case, the worker can hold the shelf board 15 in a hanging manner by holding the second handle portion 44 with the shelf board 15 held vertically. In this case, since the third arc portion 44A is formed on the second handle portion 44, the worker can hang the shelf board 15 easily. This makes the shelf board 15 easy to handle.

[0051] According to this embodiment, the following can be said: Shelf 15 comprises a flat shelf body 31 having a side portion and a recess 36 that is recessed inward from the side portion and allows a hand to be inserted, and a cover 32 attached to shelf body 31, the cover 32 having a cover body 42 that covers the side portion and a handhold portion 43 that covers the recess 36 and has an arc-shaped cross section that protrudes outward.

[0052] The trolley 11 comprises a car body 12, a first fence 13 standing up from the car body 12, a second fence 14 standing up from the car body 12 and spaced apart from the first fence 13, and a shelf 15 spanning between the first fence 13 and the second fence 14. The shelf 15 has a flat shelf body 31 having an edge and a recess 36 that is recessed inward from the edge and allows a hand to be inserted, and a cover 32 attached to the shelf body 31, the cover 32 having a cover body 42 that covers the edge and a handhold portion 43 that covers the recess 36 and has an arc-shaped cross-section that convex outward.

[0053] According to these configurations, the shelf board 15 is provided with the recess 36 recessed inward, so that when a worker lifts the shelf board 15, the worker can insert his / her hand into the recess 36 to lift the shelf board 15, and the worker can smoothly install the shelf board 15 or change the installation height of the shelf board 15. In addition, the recess 36 is covered by the handhold 43 with an arc-shaped cross section, so that the recess 36 can be prevented from digging into the hand of a worker who is holding the recess 36. As a result, the workload on the worker when lifting the shelf board 15 or changing the installation height of the shelf board 15 is reduced, and labor can be saved.

[0054] The handle portion 43 has a step portion 62 in which the recessed portion 36 is accommodated, and a top portion 63 that is provided adjacent to the step portion 62 and is flush with the surface of the shelf board body 31. According to this configuration, since the surface of the shelf board body 31 and the top portion 63 of the handle portion 43 are flush with each other, even if a product is placed at a position that straddles the shelf board body 31 and the handle portion 43, the product will not get caught on the top portion 63. This makes it possible to smoothly load and unload products, and reduces the workload of the worker. In addition, the recessed portion 36 and the upper side of the handle portion 43 can also be used as a product placement surface, and the problem of the installation space for the product being reduced due to the provision of the recessed portion 36 does not occur. This makes it possible to achieve both a reduction in the workload of the worker and a wide product installation space on the shelf board 15.

[0055] The cover body 42 has a first abutment piece 47 that abuts against the front side of the edge portion, and the handle portion 43 has a second abutment piece 65 that abuts against the back side of the recess 36. With this configuration, the front side of the shelf body 31 can be held by the first abutment piece 47 and the back side of the shelf body 31 can be held by the second abutment piece 65, so that the shelf body 31 can be held in a close position as if sandwiched from both sides. This improves the rigidity of the shelf body 31 and prevents the shelf 15 from bending significantly due to the weight of the products.

[0056] The shelf board body 31 has one or more beams 38 extending in a direction intersecting the side portions, and the recesses 36 and the handles 43 are provided at positions away from the one or more beams 38. The beam portion 38 can improve the rigidity of the shelf board 15. Furthermore, the recessed portion 36 and the handle portion 43 do not interfere with the beam portion 38, and the beam portion 38 can be installed, for example, across the entire width of the shelf board main body 31 in the direction intersecting with the side portions. This can further improve the rigidity of the shelf board 15.

[0057] The cover body 42 has a third contact piece 51 that contacts the back side of one or more beams 38, a top 63 that is continuous with the first contact piece 47, and the handle 43 has a bottom 64 that is provided on the opposite side to the top 63 and is formed so as to be continuous with the third contact piece 51. With this configuration, the rigidity of the handle 43 and the cover body 42 can be improved by adopting a structure in which they are continuous with each other.

[0058] The tip of the first contact piece 47 is positioned outside the tip of the third contact piece 51. With this configuration, a wide product installation surface can be formed on the front side of the shelf board 15. This makes it possible to reduce the workload of the worker while also ensuring a wide product installation space on the shelf board 15.

[0059] The shelf board 15 comprises a first part 42A provided on the cover body 42, a second part 42B provided on the cover body 42 on the opposite side of the first part 42A with a handle portion 43 therebetween, a second handle portion 44 provided opposite the handle portion 43 and connecting the first part 42A and the second part 42B, and a hole portion 45 provided between the handle portion 43 and the second handle portion 44 through which a hand can be passed.

[0060] According to this configuration, not only can the shelf board 15 be held by hanging it on the handle portion 43, but the shelf board 15 can also be held in one hand by hanging it on the second handle portion 44. This makes it possible to provide a shelf board 15 that is even more user-friendly for the worker.

[0061] The first fence 13 has a pair of first vertical members 23 extending from the vehicle body 12 to approximately waist height of an adult, and a first horizontal member 24 connecting approximately the tip ends of the pair of first vertical members 23, and the second fence 14 has a pair of second vertical members 26 extending from the vehicle body 12 to approximately waist height of an adult, and a second horizontal member 27 connecting approximately the tip ends of the pair of second vertical members 26, and the shelf board 15 is spanned between the first horizontal member 24 and the second horizontal member 27.

[0062] According to this configuration, the shelf board 15 can be used as the top board of the cart 11. In addition, since the cart 11 does not have a handle, products larger than the shelf board 15 can be placed on the shelf board 15. Therefore, the cart 11 can accommodate large products and is easy for workers to use.

[0063] The shelf board 15 has a first part 42A provided on the cover body 42, a second part 42B provided on the cover body 42 on the opposite side of the first part 42A with a handle portion 43 therebetween, a second handle portion 44 provided opposite the handle portion 43 and connecting the first part 42A and the second part 42B, and a hole portion 45 provided between the handle portion 43 and the second handle portion 44 through which a hand can be passed.

[0064] According to this configuration, when an operator lifts up the shelf board 15, he or she can grasp not only the handgrip 43 but also the second handgrip 44 to lift up the shelf board 15. In addition, the second handgrip 44 can be used as a handle when operating the cart 11. Therefore, the handle structure can be omitted from the fence of the cart 11, and the first fence 13 and the second fence 14 can be made into a common part, thereby reducing costs.

[0065] The diameter of the second handhold portion 44 is configured to be larger than the diameters of the first horizontal member 24 and the second horizontal member 27, and the second handhold portion 44 abuts against either the first horizontal member 24 or the second horizontal member 27. The second handhold 44 has an abutment surface 44B, and can be integrated with either the first horizontal member 24 or the second horizontal member 27 via the abutment surface 44B when the shelf board 15 is stretched between the first horizontal member 24 and the second horizontal member 27. This configuration makes it easy to use the second handhold 44 as a handle for operating the cart 11, reducing the workload of the worker.

[0066] The second handhold portion 44 has an arc-shaped cross section that is convex upward. With this configuration, when an operator pushes or pulls the cart 11, the operator can easily place his or her hand on the second handhold portion 44 from above, and the cart 11 can be structured so that the operator's hands do not hurt when operating the cart 11. This makes it possible to realize the cart 11 with a further reduced workload for the operator.

[0067] The cover body 42 has a recess 61 near the hole 45 into which either the first horizontal member 24 or the second horizontal member 27 is fitted. With this configuration, the recess 61 is provided near the hole 45 through which the worker's hand passes, making it easy for the worker to aim when aligning the recess 61 with either the first horizontal member 24 or the second horizontal member 27. This makes it possible to realize a cart 11 that is easy to work with and reduces the burden on the worker when installing the shelf board 15 so that it spans between the first fence 13 and the second fence 14 or when changing the installation height of the shelf board 15.

[0068] In the second embodiment described below, differences from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted. [Second embodiment]

[0069] A second embodiment of the cart will be described with reference to Fig. 15. In this embodiment, the configurations of the first fence 13 and the second fence 14 are different from those in the first embodiment.

[0070] The first fence 13 is provided, for example, at the front end of the vehicle body 12. The first fence 13 has a pair of first vertical members 23 standing up from the corners of the bottom plate portion 21, a first horizontal member 24 connecting the approximate tip ends of the pair of first vertical members 23, and a first intermediate horizontal member 25 connecting the intermediate positions of the pair of first vertical members 23. The tip end (upper end) of the first vertical member 23 is located at a height equal to or higher than the chest of an adult, and more preferably at a height corresponding to the height between the chest and the head of an adult. The tip end (upper end) of the first vertical member 23 may be at a height equal to or higher than the head of an adult. Here, the approximate tip end refers to the tip end of the first vertical member 23 or a portion in the vicinity of the tip end.

[0071] The second fence 14 is provided, for example, at the rear end of the vehicle body 12. The second fence 14 has a pair of second vertical members 26 standing up from the corners of the bottom plate portion 21, a second horizontal member 27 connecting the approximate tip ends of the pair of second vertical members 26, and a second intermediate horizontal member 28 connecting the intermediate positions of the pair of second vertical members 26. The tip end (upper end) of the second vertical member 26 is located at a height equal to or higher than the chest of an adult, and more preferably at a height corresponding to the height between the chest and the head of an adult. The tip end (upper end) of the second vertical member 26 may be at a height equal to or higher than the head of an adult. Here, the approximate tip end refers to the tip end of the first vertical member 23 or a portion in the vicinity of the tip end.

[0072] The shelf board 15 is, for example, detachably stretched between the first horizontal member 24 of the first fence 13 and the second horizontal member 27 of the second fence 14. Alternatively, the shelf board 15 may be detachably stretched between the first intermediate horizontal member 25 of the first fence 13 and the second intermediate horizontal member 28 of the second fence 14. The shelf board 15 is installed so as to be stretched between horizontal members of the same height between the first fence 13 and the second fence 14 so as to be disposed substantially horizontally. A plurality of shelves 15 may be installed for one cart 11 so that shelves are formed in a plurality of tiers on one cart 11.

[0073] Next, the operation of the shelf board 15 of this embodiment and the cart 11 equipped with this shelf board 15 will be described with reference to Fig. 15 etc. The shelf board 15 of this embodiment is provided with a recess 36 and a handhold 43 into which a hand can be inserted. Therefore, as shown in Fig. 15, By inserting one hand into one of the recesses 36 (holes 45) and the other hand into the other recess 36 (holes 45), the shelf board 15 can be lifted from a position between the first fence 13 and the second fence 14. Therefore, even when the shelf board 15 is installed so as to span between the first fence 13 and the second fence 14, or when the installation height of the shelf board 15 already installed between the first fence 13 and the second fence 14 is changed, the worker can lift the shelf board 15 from a position between the first fence 13 and the second fence 14 and can easily move the shelf board 15. In addition, since the handhold portion 43 has an arc-shaped cross section that is convex toward the outside, the recesses 36 do not dig into the worker's hand, making it easy for the worker to hold the shelf board 15.

[0074] As shown in FIG. 15, the dolly 11 does not have a handle. When the shelf board 15 is stretched between the first intermediate horizontal member 25 and the second intermediate horizontal member 28, the second handhold 44 is integrated with either the first intermediate horizontal member 25 or the second intermediate horizontal member 28 via the abutment surface 44B. Therefore, an operator can push the dolly 11 from the rear side or pull the dolly 11 from the front side by inserting his / her hand into the recess 36 (hole 45) of the shelf board 15 or by gripping the second handhold 44. Therefore, there is no need to provide the dolly 11 with a handle as a handle portion, and the first fence 13 and the second fence 14 can be made of a common part. This reduces the manufacturing cost of the dolly 11.

[0075] Also, as shown in Fig. 14, the worker can hang the shelf board 15 with one hand. In this case, the worker can hold the shelf board 15 in a hanging manner by holding the second handle portion 44 with the shelf board 15 held vertically. In this case, since the third arc portion 44A is formed on the second handle portion 44, the worker can hang the shelf board 15 easily. This makes the shelf board 15 easy to handle.

[0076] According to this embodiment, the following can be said. The first fence 13 has a pair of first vertical members 23 extending from the vehicle body 12 to a height above an adult's chest and a first intermediate horizontal member 25 connecting the pair of first vertical members 23, the second fence 14 has a pair of second vertical members 26 extending from the vehicle body 12 to a height above an adult's chest and a second intermediate horizontal member 28 connecting the pair of second vertical members 26, and the shelf board 15 is placed between the first intermediate horizontal member 25 and the second intermediate horizontal member 28.

[0077] According to this configuration, since a recess 36 is provided in the shelf 15, when attaching or detaching the shelf 15 from a position between the first fence 13 and the second fence 14, the worker does not need to grasp the long side portion 34 of the shelf 15, thereby improving the worker's work efficiency and reducing the workload.

[0078] The shelf board 15 has a first part 42A provided on the cover body 42, a second part 42B provided on the cover body 42 on the opposite side of the first part 42A with a handle portion 43 therebetween, a second handle portion 44 provided opposite the handle portion 43 and connecting the first part 42A and the second part 42B, and a hole portion 45 provided between the handle portion 43 and the second handle portion 44 through which a hand can be passed.

[0079] According to this configuration, not only can the shelf board 15 be held by hanging it on the handle portion 43, but the shelf board 15 can also be held in one hand by hanging it on the second handle portion 44. This makes it possible to provide a shelf board 15 that is even more user-friendly for the worker.

[0080] The cover body 42 has a recess 61 near the hole 45 into which either the first intermediate horizontal member 25 or the second intermediate horizontal member 28 is fitted. With this configuration, the recess 61 is provided near the hole 45 through which the worker's hand passes, making it easy for the worker to aim when aligning the recess 61 with either the first intermediate horizontal member 25 or the second intermediate horizontal member 28 from a position between the first fence 13 and the second fence 14. This provides excellent operability and makes it easy for the worker to position the shelf 15 between the first fence 13 and the second fence 14 or to change the installation height of the shelf 15. A trolley 11 with reduced work load can be realized.

[0081] The above-described embodiment can be embodied with various substitutions and modifications. In addition, the above-described embodiments can be combined appropriately to realize the present invention. [Explanation of symbols]
