DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The nesting rack 100 of this embodiment is rectangular in plan view and, as shown in Figure 1, has pillars 20a, 21a erected at the two corners on the front opening side and pillars 20b, 21b erected at the two corners on the rear side.

[0016] In the embodiment shown in FIG. 1, a rectangular bottom plate 30 is provided at the lower ends of the support columns 20a, 20b, 21a, and 21b. In the embodiment shown, the bottom plate 30 is rectangular in plan view, surrounded by a front edge on the front side, two side edges on both left and right sides extending in the front-rear direction from both ends of the front edge toward the back, and a back edge on the back side extending in the left-right direction perpendicular to the two side edges. In the embodiment shown, between the both side edges, two support pieces extending in the front-rear direction with a predetermined interval between them are bridged between the front edge and the back edge, and between the front edge and the back edge, two support pieces extending in the left-right direction with a predetermined interval between them are bridged between one side edge and the other side edge.

[0017] The upper parts of the pillars 20a, 20b, 21a, and 21b are connected by beams 31, 31, and 31, except for the front side.

[0018] The left-right distance between the support columns 20a and 21a on the front opening side is greater than the left-right distance between the support columns 20b and 21b on the rear side. This allows nesting racks of the same structure and size as the nesting rack 100 shown in Figure 1 to be stored in a nested manner from the front opening side toward the rear.

[0019] In addition, nesting racks of the same structure and size can be stably stacked above or below the nesting rack 100 shown in FIG.

[0020] In the illustrated embodiment, the four support columns 20a, 20b, 21a, and 21b form a rectangular body, which has engagement means 32, 32 at both lower ends on the front side and engagement means 33, 33 at both upper ends on the rear side. These are used when stably stacking the containers in the vertical direction as described above.

[0021] In the illustrated embodiment, the above-mentioned engaging means 32, 32 and engaging means 33, 33 are used to stably stack nesting racks of the same structure and size above or below the nesting rack 100 shown in Figure 1, but this is not limited to this, and nesting racks can be stably stacked in the vertical direction by using engaging means of various shapes and structures that have been conventionally adopted and used.

[0022] In the illustrated embodiment, a rectangular bottom plate 30 in plan view is provided at the lower ends of the columns 20a, 20b, 21a, and 21b, and beams 31, 31, 31 are provided at the upper ends of the columns 20a, 20b, 21a, and 21b except on the front side, but a structure or form in which beams 31, 31, 31 are provided at the lower ends of the columns 20a, 20b, 21a, and 21b and a top plate having a structure corresponding to the bottom plate 30 of the above-mentioned structure is provided at the upper ends may also be used. This is a so-called reverse nesting rack.

[0023] In a nesting rack, whether it is the nesting rack 100 shown and described above or a reverse nesting rack, a removable intermediate shelf may be arranged at a predetermined intermediate height position in the vertical direction of the supports 20a, 20b, 21a, and 21b.

[0024] When the items to be stored in the nesting rack are small or have a small vertical size, i.e., when the stored items are low in height, a large amount of unstored space may be created inside the nesting rack as shown in Fig. 1, making it impossible to use the nesting rack effectively. In order to prevent this situation from occurring, a removable intermediate shelf can be placed at a predetermined intermediate height position in the vertical direction of the supports 20a, 20b, 21a, and 21b.

[0025] The intermediate shelf is large enough to fit within a rectangle in plan view formed by the four pillars 20a, 20b, 21a, 21b of the nesting rack, and has appropriate strength depending on the application, such as for heavy-duty storage of heavy items or for light-duty storage of not so heavy items. Various structures, shapes and forms, such as lattice-like, lattice-like, board-like, mesh-frame-like, etc. have traditionally been used for the intermediate shelf.

[0026] The above-mentioned four pillars 20a, 20b, 21a, 21b, bottom plate 30, beams 31, 31, engaging means 32, 32, engaging means 33, 33, etc. that make up the nesting rack 100 are typically made of a metal such as steel, and the intermediate shelf is also often made of a metal such as steel, but may also be made of a suitable material such as light metal, synthetic resin, or in some cases wood.

[0027] When this intermediate shelf is positioned at a predetermined intermediate height position in the vertical direction of the four pillars 20a, 20b, 21a, and 21b that make up the nesting rack 100, a stopper or other fastener is placed at the desired height position on the four pillars 20a, 20b, 21a, and 21b depending on the height, size, etc. of the items to be stored, and the intermediate shelf is attached and removably positioned at that position.

[0028] The nesting rack 100 of this embodiment is shown in FIG. 1 and is a nesting rack of the conventionally known structure and configuration described above, with an improved hanging structure for attaching and detaching the intermediate shelf at a predetermined intermediate height position in the vertical direction.

[0029] The following description will focus on the latching structure of the nesting rack 100 according to this embodiment, which is an improvement over nesting racks of known structures and configurations.

[0030] The nesting rack 100 of this embodiment includes four posts 20a, 21a, 20b, and 21b, four hanging devices 1a, 1b, 11a, and 11b, and an intermediate shelf .

[0031] As shown in Figure 1, the four pillars 20a, 21a, 20b, and 21b consist of pillars 20a, 21a erected at two corners on the front opening side of nesting rack 100, which is rectangular in plan view, and pillars 20b, 21b erected at two corners on the rear side of nesting rack 100, which is rectangular in plan view.

[0032] The support 20a has a rectangular cross section and is provided with a plurality of hanging holes 24a, 24b, 24c, and 24d at predetermined intervals in the vertical direction. The hanging holes 24a, etc. are formed penetrating the support 20a in the left-right direction.

[0033] The support pillar 20b has a rectangular cross section and is provided with a plurality of hanging holes 26a, 26b, 26c, and 26d at predetermined intervals in the up-down direction. The hanging holes 26a, etc. are formed penetrating the support pillar 20b in the front-rear direction.

[0034] The support 21a has a rectangular cross section and is provided with a plurality of hanging holes 25a, 25b, 25c, and 25d at predetermined intervals in the vertical direction. The hanging holes 25a, etc. are formed penetrating the support 21a in the left-right direction.

[0035] The support pillar 21b has a rectangular cross section and is provided with a plurality of hanging holes 27a, 27b, 27c, and 27d at predetermined intervals in the up-down direction. The hanging holes 27a, etc. are formed penetrating the support pillar 21b in the front-rear direction.

[0036] In this embodiment, the sizes of the rectangular cross sections of the pillars 20a, 20b, 21a, and 21b are the same.

[0037] The hanging holes 24a to 27d formed in the pillars 20a to 21b are formed at the same vertical height position of each of the four pillars 20a to 21b. That is, the vertical height position where the hanging hole 24a is formed in the pillar 20a, the vertical height position where the hanging hole 26a is formed in the pillar 20b, the vertical height position where the hanging hole 25a is formed in the pillar 21a, and the vertical height position where the hanging hole 27a is formed in the pillar 21b are the same. The vertical height position where the hanging hole 24b is formed in the pillar 20a, the vertical height position where the hanging hole 26b is formed in the pillar 20b, the vertical height position where the hanging hole 25b is formed in the pillar 21a, and the vertical height position where the hanging hole 27b is formed in the pillar 21b are the same. The vertical height position where hanging hole 24d is formed in support 20a, the vertical height position where hanging hole 26d is formed in support 20b, the vertical height position where hanging hole 25d is formed in support 21a, and the vertical height position where hanging hole 27d is formed in support 21b are the same.

[0038] In the illustrated embodiment, the multiple hanging holes formed in each of the posts 20a to 21b are four holes spaced a predetermined distance apart in the vertical direction, but the holes can be arranged in various forms, such as one hole at a predetermined height, two holes at a predetermined height, etc., taking into account the vertical size of the items to be stored in the nesting rack 100.

[0039] The four hanging devices 1a, 1b, 11a, 11b are respectively hung on the four pillars 20a, 21a, 20b, 21b, and the four hanging devices 1a, 1b, 11a, 11b can be attached to and detached from the four pillars 20a to 21b at the positions of the above-mentioned hanging holes 24a to 27d of the four pillars 20a to 21b.

[0040] In the illustrated embodiment, the middle shelf 40 has two side edges 41b, 41d extending in the front-to-rear direction from the front opening side toward the rear side, and a rear edge 41c which is an edge extending in the left-right direction at the rear side perpendicular to the two side edges 41b, 41d.

[0041] As shown in Figures 1 and 2, the intermediate shelf 40 is positioned at the midpoint in the vertical direction between the four pillars 20a, 21a, 20b, and 21b by having two side edges 41b, 41d extending in the front-to-rear direction from the front opening side toward the rear side, and a rear edge 41c extending in the left-right direction at the rear side, hung on the four hanging devices 1a, 1b, 11a, and 11b.

[0042] In other words, by hanging the two side edges 41b, 41d and the rear edge 41c on the four hanging devices 1a, 1b, 11a, 11b, the intermediate shelf 40 is positioned at any intermediate height position in the vertical direction between the four pillars 20a to 21b.

[0043] In FIG. 1, four hanging devices 1a to 11b are attached at the height positions of the through holes 24b, 26b, 27b, and 25b, and an intermediate shelf 40 is disposed at this height position.

[0044] As described above, the four fasteners 1a, 1b, 11a, 11b are fastened to the fastener holes 24a, 24b, 24c, 24d, 25a, 25b, 25c, 25d, 26a, 26b, 26c, 26d, 27a, 27b, 27c, 27d formed at the same vertical height in the four posts 20a, 21a, 20b, 21b, respectively. In the illustrated embodiment, the fasteners include first fasteners 1a and 1b which are fastened to hanging holes 24a, 24b, 24c, and 24d of support 20a and hanging holes 26a, 26b, 26c, and 26d of support 20b, and second fasteners 11a and 11b which are fastened to hanging holes 25a, 25b, 25c, and 25d of support 21a and hanging holes 27a, 27b, 27c, and 27d of support 21b.

[0059] As shown in Figures 3 to 5 and 6 to 8, the first fastening devices 1a, 1b and the second fastening devices 11a, 11b differ only in whether the second abutment plate 4 and the fifth abutment plate 14 extend perpendicular to the first abutment plate 3 and the fourth abutment plate 13 from the left or right side edge at the lower end of the first abutment plate 3 and the fourth abutment plate 13, respectively. Otherwise, they have the same structure and size.

[0060] As an example of a state in which the hanging devices (first hanging devices 1a, 1b, second hanging devices 11a, 11b) are attached to the positions of the hanging holes 24a to 27d formed in each of the four pillars 20a, 20b, 21a, 21b that constitute the nesting rack 100 shown in Figure 1, a state in which a corresponding hanging device (second hanging device 11a) is attached to the pillar 21a located on the right side toward the front opening side of the nesting rack 100 will be described below with reference to Figures 9 to 12, taking an example in which the second hanging device 11a is attached to the pillar 21a at the position where the hanging hole 25b of the pillar 21a is formed.

[0061] Fig. 9 is a diagram illustrating a state in which the second support rod 12 is inserted into the hook hole 25b of the support 21a to attach the second hook 11a to the support 21a, and Fig. 9(a) is a side view illustrating the relationship between the position and extending direction of the hook hole 25b formed in the support 21a and the extending direction of the second support rod 12. Fig. 9(b) is a cross-sectional view of the support 21 in the state illustrated in Fig. 9(a) as viewed from above.

[0062] Fig. 10(a) is a side view of the second fastener 11a rotated 90 degrees in the direction indicated by the arrow 100 in Fig. 9(a) from the state shown in Fig. 9(a). Fig. 10(b) is a cross-sectional view of the support 21a in the state shown in Fig. 10(a) in a plan view.

[0063] Fig. 11(a) is a side view showing a state in which the second hook 11a is advanced in the direction shown by the arrow 101 in Fig. 10(a) from the state shown in Fig. 10(a) to insert the second support rod 12 into the hook hole 25b of the support pillar 21a. Fig. 11(b) is a cross-sectional view of the support pillar 21a in the state shown in Fig. 11(a) in a plan view.

[0064] Fig. 12(a) is a side view showing a state in which the second fastener 11a is attached to the support pillar 21a by rotating the second fastener 11a by 90 degrees in the direction shown by the arrow 102 in Fig. 11(a) from the state shown in Fig. 11(a). Fig. 12(b) is a cross-sectional view of the support pillar 21a in the state shown in Fig. 12(a) in a plan view.

[0065] As shown in Figure 12(a), the fourth abutment plate 13 is flat and extends in a direction perpendicular to the second support rod 12 to support the second support rod 12. When the second support rod 12 is inserted into the hanging hole 25b of the support 21a, the fourth abutment plate 13 abuts against a fifth outer wall surface 23a among the four outer wall surfaces 23a, 23b, 23c, and 23d of the support 21a, and extends downward, with the side supporting the second support rod 12 being the upper side in the vertical direction of the support 21a.

[0066] 12(a) and (b), the fifth abutment plate 14 is flat and extends from the side edge of the lower end of the fourth abutment plate 13 perpendicular to the fourth abutment plate 13 to abut against a sixth outer wall surface 23b perpendicular to the fifth outer wall surface 23a of the support 21a.

[0067] As shown in Figures 12(a) and (b), the sixth abutment plate 15 is flat, extends perpendicular to the tip edge of the fifth abutment plate 14, faces the fifth outer wall surface 23a of the support 21a, and abuts against the seventh outer wall surface 23c perpendicular to the sixth outer wall surface 23b.

[0068] As shown in Figures 12(a) and (b), the second support plate 6 is flat and extends from the tip edge of the lower end side of the fourth abutment plate 13 perpendicular to the fourth abutment plate 13 in the opposite direction to the extension direction of the fifth abutment plate 14.

[0069] In the above-mentioned Figures 9 to 12, as an example of attaching the second hanging devices 11a, 11b to the posts 21a, 21b of the nesting rack 100 shown in Figure 1, an example has been described in which the second hanging device 11a is attached to the post 21a at a position where the hanging hole 25b of the post 21a is formed.

[0070] As described above, the first fasteners 1a, 1b and the second fasteners 11a, 11b differ only in whether the second abutment plate 4 and the fifth abutment plate 14 extend perpendicular to the first abutment plate 3 and the fourth abutment plate 13 from the left or right side edge of the lower end of the first abutment plate 3 and the fourth abutment plate 13, as shown in Figures 3 to 5 and 6 to 8, but otherwise have the same structure and size.

[0071] Therefore, when the first hanging devices 1a, 1b are attached to the pillars 20a, 20b of the nesting rack 100 shown in Figure 1, this can be done in the same manner as when the second hanging devices 11a, 11b are attached to the pillars 21a, 21b, as described with reference to Figures 9 to 12.

[0072] That is, the hanging devices 1 and 11 employed in this embodiment are hanging devices that are attached to a vertically extending and erected support pillar with a rectangular cross section, such as the pillars 20a, 20b, 21a, and 21b shown in Figure 1, and are used to support an object to be supported, such as an intermediate shelf 40, in a horizontal position.

[0073] A support rod 2 is inserted into horizontally extending hook holes 24a to 24d of a vertically extending support having a rectangular cross section, for example, a support rod 20a shown in FIG. 1, a flat first contact plate 3 that supports the support rod 2 at its upper end and extends downward while contacting a first outer wall surface 22a of the support rod 20a, and a second outer wall surface 22b that extends perpendicular to the first contact plate 3 from one or the other side edge of the lower end of the first contact plate 3 and perpendicular to the first outer wall surface 22a of the support rod 20a. Alternatively, it is provided with a flat second abutment plate 4, 14 that abuts against the fourth outer wall surface 22d, a flat third abutment plate 5, 15 that extends perpendicular to the tip edge of the second abutment plate 4, 14, faces the first outer wall surface 22a of the support 20a, and abuts against the second outer wall surface 22b or the third outer wall surface 22c that is perpendicular to the fourth outer wall surface 22d, and a flat support plate 6, 16 that extends from the tip edge of the lower end side of the first abutment plate 3 perpendicular to the first abutment plate 3 and in the opposite direction to the extension direction of the second abutment plate 4, 14.

[0074] As described above, the hanging structure of this embodiment is a hanging structure that has hanging holes 24a-27d extending horizontally, and is composed of a rectangular cross-sectional pillar that extends vertically and is erected, such as the pillars 20a, 20b, 21a, and 21b shown in FIG. 1, and hanging devices 1 and 11 of the structure described above, and is used to support an object to be supported, that is, a supported object, in a horizontal state.

[0075] When such a hanging structure is adopted for the nesting rack 100 shown in Figure 1, the above-mentioned pillars 20a, 20b, 21a, 21b are erected at each corner of the rectangular shape that constitutes the nesting rack 100 when viewed in a plane, and the pillars 20a, 21a erected on the front opening side of the nesting rack 100 have hanging holes 24a, -, 24d, 25a, -, 25d that penetrate in the left-right direction, and the pillars 20b, 21b erected on the rear side have hanging holes 26a, -, 26d, 27a, -, 27d that penetrate in the front-rear direction from the front opening side toward the rear side.

[0076] As shown in Figure 13, which shows a plan view with some parts omitted, the side edge 41b of the middle shelf 40 is supported by a first hanging device 1a attached to the support pillar 20a, the rear edge 41c of the middle shelf 40 is supported by the first hanging device 1a attached to the support pillar 20b and the second hanging device 11b attached to the support pillar 21b, and the side edge 41c of the middle shelf 40 is supported by the second hanging device 11a attached to the support pillar 21a.

[0077] That is, the first fastener 1a is attached to the post 20a at a position where the fastener holes 24a to 24d are formed, and the first support plate 6 supports the lower surface of the side edge 41b of the intermediate shelf 40 horizontally.

[0078] The first fastener 1b is attached to the post 20b at a position where the fastener holes 26a to 26d are formed, and the first support plate 6 supports the lower surface of the rear edge 41c of the intermediate shelf 40 horizontally.

[0079] The second fastener 11b is attached to the post 21b at a position where the fastener holes 27a to 27d are formed, and the second support plate 16 supports the lower surface of the rear edge 41c of the intermediate shelf 40 horizontally.

[0080] The second fastener 11a is attached to the post 21a at a position where the fastener holes 25a to 25d are formed, and the second support plate 16 supports the lower surface of the side edge 41d of the intermediate shelf 40 horizontally.

[0081] When the first support plate 6 of the first hanging devices 1a, 1b has a hanging piece portion 7 rising obliquely upward from its tip edge as shown in FIG. 3, and the second support plate 16 of the second hanging devices 11a, 11b has a hanging piece portion 17 rising obliquely upward from its tip edge as shown in FIG. 6, the side edge 41b of the intermediate shelf 40 is supported horizontally by the first support plate 6 of the first hanging device 1a attached to the support post 20a as shown in FIG. 13 with some parts omitted. When the rear edge 41c of the intermediate shelf 40 is supported horizontally by the first support plate 6 of the first hanging device 1b attached to the support pillar 20b and by the second support plate 16 of the second hanging device 11b attached to the support pillar 21b, and the side edge 41c of the intermediate shelf 40 is supported horizontally by the second support plate 16 of the second hanging device 11a attached to the support pillar 21a, the presence of the hanging pieces 7, 17 advantageously prevents the intermediate shelf 40 from moving left-right and front-to-back.

[0082] The hanging devices (first hanging devices 1a, 1b, second hanging devices 11a, 11b) employed in the hanging structure of this embodiment are used as described above, and therefore can be made of metal such as steel, like the four pillars 20a, 20b, 21a, 21b, bottom plate 30, beams 31, 31, engaging means 32, 32, engaging means 33, 33, etc., which constitute the nesting rack 100. Also, as long as the required strength can be exhibited, they can be made of an appropriate material such as light metal or synthetic resin.

[0083] Although an embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiment and can be modified in various ways within the technical scope as understood from the description of the claims.

[0084] For example, in the above, the hanging devices (first hanging devices 1a, 1b, second hanging devices 11a, 11b) are attached to the four pillars 20a, 20b, 21a, 21b at the positions where the hanging holes 24b, 26b, 27b, 27b are formed, and the intermediate shelf 40 is arranged at this vertical height position, but it is also possible to attach the hanging devices (first hanging devices 1a, 1b, second hanging devices 11a, 11b) to the four pillars 20a, 20b, 21a, 21b at the positions where the hanging holes 24a, 26a, 27a, 27a are formed, and arrange the intermediate shelf 40 at this vertical height position.

[0085] In addition, in the above, four hanging holes 24a to 27d are formed on each of the four supports 20a, 20b, 21a, and 21b at a predetermined interval in the vertical direction, but taking into account the size of the articles to be stored in the nesting rack 100, it is possible to form the rack so that three hanging holes are formed on each of the supports.
