[0020] The tray rack of this embodiment will be described below with reference to the drawings. The tray rack of this embodiment is a cart that can hold multiple trays and is suitable for use in stores when stocking products such as fresh food from the back yard to the sales floor. [First embodiment]

[0021] As shown in FIGS. 1 to 3, the tray rack 11 includes a plurality of support columns 12 extending vertically, one or more shelves 13 extending horizontally between the support columns 12, trays 14 placed on the shelves 13, and a plurality of casters 15 attached to the lower ends of the support columns 12. The support columns 12 can connect the shelves 13 together in the vertical direction. In this embodiment, for example, four support columns 12 are provided corresponding to four corners 16 (see FIG. 4) of the shelf 13. The number of support columns 12 is arbitrary, and the plurality of support columns 12 are provided at any or all of the four corners 16. The support columns 12 may be made of, for example, a synthetic resin material or a metal material. The casters 15 are made of commonly available casters.

[0022] The tray 14 is configured as a flat plate with raised edges to prevent products placed on it from falling off. The tray 14 has a generally rectangular shape when viewed from above. The tray 14 may be made of, for example, a synthetic resin material or a metal material.

[0023] In this embodiment, the number of shelf boards 13 is four. The number of shelf boards 13 is not limited to this. The number of shelf boards 13 may be three or less, or five or more.

[0024] The shelf boards 13 are integrally molded from, for example, a synthetic resin material. As shown in Figs. 4 to 8, each shelf board 13 includes a substantially flat plate-shaped shelf board body 23 including a front surface 21 and a back surface 22, a pair of first side portions 24 extending in a longitudinal direction L of the shelf board 13 (shelf board body 23), a pair of second side portions 25 extending in a lateral direction S intersecting with the longitudinal direction L of the shelf board 13 (shelf board body 23), four corner portions 16 provided at positions where the pair of first side portions 24 and the pair of second side portions 25 intersect, a pair of first protrusions 26 protruding upward from each of the pair of first side portions 24, and a pair of second side portions 25 protruding upward from each of the pair of second side portions 25. The shelf board has a pair of second raised portions 27 that rise upward from the first raised portions 26, one or more first cutout portions 31 provided in each of the pair of first raised portions 26, one or more second cutout portions 32 provided in each of the pair of second raised portions 27, a first recess 33 provided at a position overlapping the first cutout portion 31, a third cutout portion 35 extending from the second side portion 25 towards an intermediate portion 34 in the longitudinal direction L, a cutout portion 36 provided in the central portion of the shelf board body 23, and a pair of beam portions 37 that extend in the longitudinal direction L and define part of the periphery of the cutout portion 36.

[0025] 12, the first side portion 24 is formed at an angle so that the height of the surface 21 decreases toward the outside in the short side direction S. The first raised portion 26 is provided as a protrusion that protrudes upward from the top of the first side portion 24. The first raised portion 26 surrounds the periphery of the placement location where the tray 14 is placed.

[0026] 4, 6, and 7, in this embodiment, a pair of first cutouts 31 are provided for each first raised portion 26. The first cutouts 31 are provided in pairs for each first raised portion 26, at positions spaced apart from each other in the longitudinal direction L. The pair of first cutouts 31 are provided in positions between the corner 16 and an intermediate position 26A of the first raised portion 26 in the longitudinal direction L, and are provided so as to cut out the first raised portion 26.

[0027] Each of the first cutouts 31 is recessed in a cone shape relative to the surrounding portion of the first protrusion 26. The first cutouts 31 are formed so that the height of their bases is flush with the height of the surrounding shelf body 23. A user can insert their fingers through the first cutouts 31 into the underside of the tray 14 placed on the shelf 13 (shelf body 23).

[0028] The first recess 33 is provided in the shelf body 23 so as to be recessed relative to the surrounding portion of the shelf body 23. More specifically, the first recess 33 is provided so as to straddle a position overlapping with the first cutout portion 31 and a part of the shelf body 23. The first recess 33 may be provided in a position adjacent to the first cutout portion 31. The first recess 33 is formed in a mortar shape so as to widen as it goes upward. As shown in Figures 5 and 10, the bottom of the first recess 33 is formed as a through-hole that penetrates the shelf body 23.

[0029] 10, second side portion 25 is formed at an angle so that the height of surface 21 decreases toward the outside in longitudinal direction L. Second raised portion 27 is provided as a protrusion that protrudes upward from the top of second side portion 25. Second raised portion 27 surrounds the periphery of the placement location where tray 14 is placed.

[0030] 9, in this embodiment, one second cutout 32 is provided for the second protrusion 27. The second cutout 32 is provided at an intermediate position 27A of the second protrusion 27 in the short-side direction S.

[0031] As shown in FIGS. 4 to 6, the third cutout 35 is cut out in a generally parabolic shape that convexes from the second side 25 toward the intermediate portion 34 in the longitudinal direction L. The third cutout 35 may be cut out in a semicircular or semi-elliptical shape. In this embodiment, the third cutout 35 is formed integrally with the second cutout 32. As shown in FIGS. 4, 5, and 10, the cross section of the third cutout 35 is bent to form a generally L-shape (an L-shape with arcuate corners). This minimizes a decrease in rigidity around the third cutout 35, preventing the shelf board 13 from easily bending.

[0032] As shown in Figures 4 to 6, the lightening portion 36 is provided in the center of the shelf board 13 and is formed into a substantially rectangular shape when viewed from above. The lightening portion 36 contributes to reducing the weight of the shelf board 13. Each cross section of the outer edge of the lightening portion 36 is formed by bending so as to form a substantially L-shape (an L-shape with arcuate corners), similar to the third cutout portion 35. This minimizes a decrease in rigidity around the lightening portion 36, preventing the shelf board 13 from easily bending.

[0033] The pair of beam portions 37 define part of the outer edge of the lightening portion 36. The width dimension of each of the pair of beam portions 37 in the short direction S increases toward the middle portion 34 in the longitudinal direction L. Therefore, as shown in Figures 4, 5, and 8, the beam portions 37, together with the cross-sectional shape of the outer edge of the lightening portion 36, are prevented from twisting around the central axis 41 as much as possible, and even when the lightening portion 36 is provided to reduce the weight of the shelf board 13, the rigidity of the shelf board 13 can be increased.

[0034] Next, the operation of the tray rack 11 of this embodiment will be described with reference to FIGS. 1 to 3, etc. Multiple trays 14 can be placed on the multiple shelves of the tray rack 11. One tray 14 can be placed on each shelf 13. The tray 14 is held in a position surrounded by the first raised portion 26 and the second raised portion 27 on the shelf 13. As shown in FIG. 2, the tray 14 can be removed in the longitudinal direction L of the shelf 13. That is, a user can use one hand to insert their fingers under the tray 14 through the first notch 31 and the first recess 33 on the first side 24 side and lift one end of the tray 14. Similarly, a user can use their other hand to insert their fingers under the tray 14 through the second notch 32 on the second side 25 side and the third notch 35 connected thereto and lift the other end of the tray 14.

[0035] Furthermore, if necessary, the user can use their left hand to insert their fingers under the tray 14 through the first cutout 31 and first recess 33 on the left side to lift the left end of the tray 14, and can use their right hand to insert their fingers under the tray 14 through the first cutout 31 and first recess 33 on the right side to lift the right end of the tray 14. By using either of these methods, the tray 14 can be removed in the longitudinal direction L. After removing the tray 14 in the longitudinal direction L, or if necessary, with the tray 14 still placed on the shelf 13, the user can perform any necessary operations, such as stocking products.

[0036] Similarly, tray 14 can be removed in the short-side direction S of shelf 13, as shown in Fig. 3. That is, a user can use one hand to insert their fingers under tray 14 through first notch 31 on first side 24 and lift one end of tray 14. The user can use their other hand to insert their fingers under tray 14 through second notch 32 on second side 25 and third notch 35 connected thereto and lift the other end of tray 14.

[0037] Furthermore, if necessary, the user can use their left hand to insert their fingers under the tray 14 through the first cutout 31 on the left side to lift the left end of the tray 14, or use their right hand to insert their fingers under the tray 14 through the first cutout 31 on the right side to lift the right end of the tray 14. By using either of these methods, the user can remove the tray 14 in the short-edge direction S. After removing the tray 14 in the short-edge direction S, or if necessary, with the tray 14 still placed on the shelf 13, the user can perform necessary operations such as stocking products. According to this embodiment, because the tray 14 can be removed in the short-edge direction S, product stocking can be performed smoothly even in sales areas where work space is limited.

[0038] According to this embodiment, the following can be said: The tray rack 11 is made up of a plurality of support columns 12 and one or more shelf boards 13 stretched between the plurality of support columns 12, and includes one or more shelves each having a pair of first side portions 24 extending in a longitudinal direction L, a pair of second side portions 25 extending in a lateral direction S intersecting the longitudinal direction L, a pair of first raised portions 26 protruding upward from each of the pair of first side portions 24, and a pair of second raised portions 27 protruding upward from each of the pair of second side portions 25. The tray 14 is capable of being placed on the shelf 13 at a position surrounded by a plate 13, a pair of first raised portions 26 and a pair of second raised portions 27, a first notch 31 provided in the pair of first raised portions 26 through which fingers can be inserted to the underside of the tray 14, and a second notch 32 provided in the pair of second raised portions 27 through which fingers can be inserted to the underside of the tray 14.

[0039] With this configuration, when removing tray 14 located inside first raised portion 26 and second raised portion 27, the user can easily insert their fingers under tray 14. This allows tray 14 located inside first raised portion 26 and second raised portion 27 to be easily pulled out from shelf board 13.

[0040] Tray rack 11 has first recesses 33 formed to be recessed more than the surrounding areas on shelf board 13 at least one of a position overlapping first cutout 31 and a position adjacent to first cutout 31. This configuration allows users to insert their fingers under trays 14 more easily. This makes it possible to realize tray rack 11 that makes it even easier for users to remove trays 14.

[0041] The first recess 33 is formed by a through-hole that penetrates at least a portion of the shelf board 13. This configuration prevents water and the like from accumulating in the first recess 33 when cleaning the tray rack 11, improving cleaning performance. Also, when removing the tray 14, the tray 14 can be lifted by inserting a finger into the through-hole. This improves the ease of removing the tray 14.

[0042] The multiple support columns 12 are provided at corners 16 where the first side 24 and the second side 25 intersect. With this configuration, the support columns 12 do not get in the way when removing the trays 14 from the shelves 13 in the short direction S. Therefore, with the above configuration, the trays 14 can be removed not only in the long direction L but also in the short direction S. This allows for smooth product removal operations even when work space is limited in a sales area, for example.

[0043] The tray rack 11 includes a third cutout 35 cut out in a generally parabolic shape that protrudes from the second side 25 of the shelf 13 toward the intermediate portion 34 in the longitudinal direction L. This configuration makes it easier for a user to insert their fingers underneath the tray 14 when removing the tray 14 in the longitudinal direction L, improving workability. Furthermore, the area surrounding the third cutout 35 widens from the corner 16 toward the intermediate portion 34 in the longitudinal direction L, thereby maintaining sufficient strength at the corner 16. Furthermore, forming the third cutout 35 in a parabolic shape prevents stress concentration near the apex of the third cutout 35, minimizing cracking near the apex. These features improve workability for users while maintaining the strength of the tray rack 11.

[0044] The tray rack 11 comprises a hollowed-out portion 36 provided in the center of the shelf board 13, and a pair of beam portions 37 extending in the longitudinal direction L, defining the periphery of the hollowed-out portion 36, and having a width dimension in the short direction S increasing toward the intermediate portion 34 in the longitudinal direction L.

[0045] This configuration can minimize the risk of the shelf boards 13, which also function as strength members of the tray rack 11, being twisted and bent around the central axis 41 of the beam portion 37. This prevents the rigidity of the tray rack 11 from being significantly reduced even when the support posts 12 are disposed at the corners 16 of the shelf boards 13. [Second embodiment]

[0046] A tray rack 11 of the second embodiment will be described with reference to Figures 13 and 14. Here, the parts different from the first embodiment will be mainly described, and a description of the parts common to the first embodiment will be omitted.

[0047] The first recess 33 is recessed relative to the surrounding portion of the shelf body 23. The first recess 33 is formed in a mortar shape so as to widen as it goes upward. As shown in Figures 13 and 14, the first recess 33 does not penetrate the shelf body 23 and is formed in a mortar shape with a bottom.

[0048] Even in this embodiment, the tray rack 11 is less easy to clean than the first embodiment, but the trays 14 can be easily pulled out from the shelf boards 13 via the first recesses 33. [Third embodiment]

[0049] A tray rack 11 of the third embodiment will be described with reference to Fig. 15. Here, differences from the second embodiment will be mainly described, and descriptions of parts common to the second embodiment will be omitted.

[0050] In this embodiment, the first recess 33 is omitted. Although this embodiment is less easy to insert fingers under the tray 14 than the second embodiment, the tray 14 can be easily pulled out from above the shelf board 13 via the first notch 31 and the second notch 32. [Fourth embodiment]

[0051] A tray rack 11 of the fourth embodiment will be described with reference to Figures 16 and 17. Here, the parts different from the first embodiment will be mainly described, and a description of the parts common to the first embodiment will be omitted.

[0052] In this embodiment, the third cutout portion 35 is omitted. Instead of the third cutout portion 35, the shelf board 13 has a second recess 43 at a position overlapping the second cutout portion 32.

[0053] In this embodiment, the second cutouts 32 are provided at intermediate positions 27A of the second raised portions 27 in the short direction S. Each of the second cutouts 32 is recessed in a cone shape relative to the surrounding portions of the second raised portions 27. The second cutouts 32 are formed so that the height of their bases is flush with the height of the shelf body 23. A user can insert their fingers through the second cutouts 32 into the underside of the tray 14 placed on the shelf 13 (shelf body 23).

[0054] The second recess 43 is provided in the shelf body 23 so as to be recessed relative to the surrounding portion of the shelf body 23. More specifically, the second recess 43 is provided so as to straddle a position overlapping with the second cutout portion 32 and a part of the shelf body 23. The second recess 43 may be provided in the vicinity of the second cutout portion 32. The second recess 43 is formed in a mortar shape so as to widen as it goes upward. As shown in Figures 16 and 17 , the bottom of the second recess 43 is formed as a through-hole that penetrates the shelf body 23.

[0055] According to this embodiment, the following can be said: The tray rack 11 has a second recess 43 formed to be recessed more than the surrounding parts on the shelf board 13 at a position overlapping with the second cutout portion 32 and / or a position adjacent to the second cutout portion 32.

[0056] This configuration allows the user to insert his or her fingers more easily under the tray 14. This makes it possible to realize a tray rack 11 that makes it even easier for the user to remove the tray 14.

[0057] The second recess 43 is configured as a through-hole that at least partially penetrates the shelf board 13. This configuration prevents water and the like from accumulating in the second recess 43 when cleaning the tray rack 11, thereby improving cleaning properties. [Fifth embodiment]

[0058] A tray rack 11 of the fifth embodiment will be described with reference to Figures 18 and 19. Here, the parts that differ from the fourth embodiment will be mainly described, and a description of the parts that are common to the fourth embodiment will be omitted.

[0059] The second recess 43 is recessed relative to the surrounding portion of the shelf body 23. The second recess 43 is formed in a mortar shape so as to widen as it goes upward. As shown in Figures 18 and 19, the second recess 43 does not penetrate the shelf body 23 and is formed in a mortar shape with a bottom.

[0060] In this embodiment, the tray rack 11 is less easy to clean than in the fourth embodiment, but the trays 14 can be easily pulled out from the shelf boards 13 via the second recesses 43. [Sixth embodiment]

[0061] A tray rack 11 of the sixth embodiment will be described with reference to Fig. 20. Here, differences from the fifth embodiment will be mainly described, and descriptions of parts common to the fifth embodiment will be omitted.

[0062] In this embodiment, the first recess 33 and the second recess 43 are omitted. Although this embodiment is less easy to insert fingers under the tray 14 than the fifth embodiment, the tray 14 can be easily pulled out from above the shelf board 13 via the first notch 31 and the second notch 32. [Seventh embodiment]

[0063] A tray rack 11 of the seventh embodiment will be described with reference to Fig. 21. Here, the parts different from the fifth embodiment will be mainly described, and a description of the parts common to the fifth embodiment will be omitted.

[0064] 21 , the first recess 33 is recessed in a substantially square shape, spanning both a position overlapping with the first cutout 31 and a position adjacent to the first cutout 31. Similarly, the second recess 43 is recessed in a substantially square shape, spanning both a position overlapping with the second cutout 32 and a position adjacent to the second cutout 32. The shape of the second recess 43 is the same as that of the first recess 33 (the second recess 43 is not shown in the drawing).

[0065] In this embodiment as well, the user can insert his or her fingers under the tray 14 through the first recess 33 and the second recess 43. This allows the tray 14 to be easily pulled out from above the shelf board 13. [Eighth embodiment]

[0074] A tray rack 11 of the tenth embodiment will be described with reference to Fig. 24. Here, differences from the fifth embodiment will be mainly described, and descriptions of parts common to the fifth embodiment will be omitted.

[0075] As shown in FIG. 24 , the shelf 13 has a first recess 51 provided on the side of the first protrusion 26 facing the tray 14, instead of the first cutout 31. That is, in this embodiment, the first protrusion 26 remains at the position where the first recess 51 was provided. In this embodiment, the first recess 33 is formed as a substantially rectangular recess spanning both a position overlapping the first recess 51 and a position adjacent to the first recess 51. The first recess 33 does not penetrate the shelf body 23 and has a bottom. A user can insert their fingers under the tray 14 through the first recess 51 and the first recess 33.

[0076] Similarly, instead of the second notch 32, the shelf 13 has a second recessed portion provided on the side of the second raised portion 27 facing the tray 14. That is, in this embodiment, the second raised portion 27 remains at the position where the second recessed portion was provided. In this embodiment, the second recessed portion 43 is formed as a substantially rectangular recess spanning both a position overlapping the second recessed portion and a position adjacent to the second recessed portion. The shape of the second recessed portion is the same as that of the first recessed portion 51 (the second recessed portion is not shown). The second recessed portion 43 does not penetrate the shelf body 23 and has a bottom. A user can insert their fingers under the tray 14 through the second recessed portion and the second recessed portion 43.

[0077] In this embodiment, too, the user can insert their fingers under the tray 14 through the first recess 51, the first concave portion 33, the second recess, and the second concave portion 43. This allows the tray 14 to be easily pulled out from the shelf board 13. [Eleventh embodiment]

[0078] The tray rack 11 of the eleventh embodiment will be described with reference to Fig. 25. Here, the parts that differ from the fourth embodiment will be mainly described, and the parts that are common to the fourth embodiment will not be described.

[0079] As shown in FIG. 25 , the shelf 13 has a first recessed portion 51 provided on the side of the first raised portion 26 facing the tray 14, instead of the first cutout portion 31. That is, in this embodiment, the first raised portion 26 remains at the position where the first recessed portion 51 is provided. In this embodiment, the first recessed portion 33 is formed as a substantially rectangular recess that spans both a position overlapping the first recessed portion 51 and a position adjacent to the first recessed portion 51. The bottom of the first recessed portion 33 is formed as a through-hole that penetrates the shelf body 23. A user can insert their fingers under the tray 14 through the first recessed portion 51 and the first recessed portion 33.

[0080] Similarly, instead of the second notch 32, the shelf 13 has a second recessed portion provided on the side of the second raised portion 27 facing the tray 14. That is, in this embodiment, the second raised portion 27 remains at the position where the second recessed portion was provided. In this embodiment, the second recessed portion 43 is formed as a substantially rectangular recess spanning both a position overlapping the second recessed portion and a position adjacent to the second recessed portion. The shape of the second recessed portion is the same as that of the first recessed portion 51 (the second recessed portion is not shown). The second recessed portion 43 is formed as a through-hole that penetrates the shelf body 23. A user can insert their fingers under the tray 14 through the second recessed portion and the second recessed portion 43.

[0081] In this embodiment, too, the user can insert their fingers under the tray 14 through the first recess 51, the first concave portion 33, the second recess, and the second concave portion 43. This allows the tray 14 to be easily pulled out from the shelf board 13.

[0082] The above-described embodiment can be further embodied with various substitutions and modifications, and it goes without saying that the above-described different embodiments can be appropriately combined to form a single invention. [Explanation of symbols]
