The structure of the returnable case 1 according to the present embodiment has been described above. Among the components, particularly long ones, that is, the upper side frames 6, 18 and the bottom side frame constituting the long side frame 3 and the short side frame 4, respectively. 7, 19, corner struts 8, 20, reinforcing struts 9, 21, trusses 11, 22, guard member 5, and skid 2, sliding material 30, foot material 31, and header 32 are hollow rectangular material having a rectangular cross section. By doing so, the overall weight is reduced.

Next, how to assemble the returnable case 1 will be described. In advance, on each of the mounting plates 13 and 25,
The clip nut 50 is mounted with the nut 53 inside.

[First Stage of Assembly] The bottom frame 19 of the short side frame 4 is placed on one header 32 of the skid 2 by sandwiching the bottom frame 19 between a pair of steady rest patches 33, so that the corner guides on both sides are provided. 35 and each mounting plate 25
The bolts 54 are screwed into the nuts 53 of the clip nuts 50, and one short side frame 4 is fixed to one short side portion of the skid 2.

[Second Stage of Assembly] Two Long Side Frames 3
Of the short side frame 4 and the mounting plate 13 which have already been erected by placing the bottom frame 7 on the foot members 31 at both ends between the center and end steadying patches 37 and 38 so as to be self-standing. Bolt insertion holes 29, 1
4 and the bolts 54 are screwed into the nuts 53 of the clip nuts 50, and the long side frames 3 are fixed to both long side portions of the skid 2. After one long-side frame 3 and two short-side frames 4 are assembled on the skid 2 in this manner, transport articles such as a cardboard case are stacked on the skid 2 from the side opening where the long-side frame 3 is to be assembled. And accommodate.

[Third Stage of Assembly] The other long-side frame 3 is assembled in the same manner as described above, and the guard member 5 is parallel to the long-side frame 3 to each of the reinforcing columns 21 of the short-side frame 4. It is bridged to the corresponding predetermined position, the engaging plates 40 at both ends are engaged with the upper side frame 18, and the matching mounting plate 25 and the engaging plates 40 are joined together by bolts 54.

As described above, the assembling of the returnable case 1 in a state in which the articles are stored is completed, and the returnable case 1 is transported as it is, for example, in a container by a forklift or the like in a container.

The returnable case 1 can be disassembled into a compact storage state after the goods have been transported and become empty. The method will be described.

[First Stage of Disassembly and Storage] By releasing the connection by the bolts 54 in all the parts, the guard member 5 is removed and the frames 3, 4 are left standing independently. The side frame 3 is removed from the steady rest patches 37 and 38, and the side frame 3 is placed on the skid 2 with the bottom frame 7 as an axis. The lower end of the corner support 8 is placed on the plate 34 a of the corner guide 35. . As described above, since the lower end of the corner post 8 protrudes below the width of the foot material 31 of the skid 2, the bottom frame 7 is located inside without interfering with the inner end steadying patch 38, Therefore, the pair of long side frames 3 overlap and are placed exactly on the surface of the deck plate 39 of the skid 2.

[Third Stage of Disassembly and Storage] A pair of short side frames 4 are laid on the skid 2 with the bottom frame 19 side as an axis. In this mounting state, the thickness of each member and the height of the header 32 are set so that each member mounted on the skid 2 does not exceed the height of the header 32 of the skid 2. .

[Second Stage of Disassembly and Storage] The guard member 5 is bridged between the headers 32 of the skid 2 and the engaging plate 40 is engaged with the header 32.

[Fourth Stage of Disassembly and Storage] As described above, the returnable case 1 folded and stored two-dimensionally (in a planar manner) on the corner guide 35 as shown in FIGS. By stacking, many are stacked and stored in a small space.

According to the returnable case 1 of the present embodiment, when stacking at the time of assembling, the protrusions 27a at the four corners formed on the corner guide 27 above the short side frame 4.
Are fitted into the fitting holes 31a at the four corners formed on the lower surface of the foot member 31 at both ends of the skid 2, so that the stacked state is favorably and stably maintained. In addition, the protrusion 27a is
The structure to be fitted into 1a functions effectively in the following cases.

As shown in FIG. 11, when a returnable case 60 having the same configuration as the returnable case 1 of the above embodiment and having a length exactly twice as long as the returnable case 1 is arranged on two returnable cases 1. When the returnable case 60 is placed at the center of the arranged returnable cases 1, the returnable case 60 can be stacked without any obstacle. The returnable case 60 includes a skid 61 and a long side frame 6.
2 and the short side frame (not shown)
The returnable case 1 of the present embodiment is assembled upward using the same corner guide 63 as described above, which is disposed at the upper end of the frame 1 and the upper end where the frames are joined. If a corner guide is also provided with a corner guide,
And the stacking becomes impossible. However, in the returnable case 1 of the present embodiment, the configuration is such that the corner guide does not protrude upward, and as a result, stacking on the upper side is possible. In addition, in the case of FIG. 11, the protrusion 2
A fitting hole to be fitted into 7a is formed.

According to the returnable case 1 of this embodiment, when assembling the frame 4, the base frame 19 is sandwiched between the center steady rest patch 37 and the end steady rest patch 38 arranged in a staggered manner. First, at this time, since the center steady rest patch 37 is higher than the width of the bottom frame 19, the short side frame 4 can be made to stand more stably and the assembling work is facilitated.

Further, when disassembling and storing, especially when the long side frame 3 is laid down on the skid 2,
The lower end of corner post 8 of long side frame 3 is skid 2
Projecting below the width of the foot material 31, the bottom frame 7 is connected to the inner end steadying patch 38 as described above.
And the pair of long side frames 3 can be placed exactly on the surface of the deck plate 39 of the skid 2. For this reason, the returnable case 1 at the time of storage does not need to be thick, and compactness at the time of storage can be achieved.

The returnable case 1 which constitutes each surface of the returnable case 1 at the time of assembly (the upper frames 6, 18, the lower frames 7, 19, the corner posts 8, 20) is a plate material that covers the entire surface. Instead, it is a prismatic member, and as described above, is hollow, so that significant weight reduction is realized.
