After assembling one long side frame 3 and two short side frames 4 on the skid 2 in this way, transportation 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 next. And house.

[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 arranged parallel to the long side frame 3 on each of the reinforcing columns 21 of the short side frame 4. It is bridged to a corresponding predetermined position, the engaging plates 40 at both ends are engaged with the upper frame 18, and the mounting plate 25 and the engaging plates 40 which are matched are joined with a bolt 54.

As described above, the assembling of the returnable case 1 containing the articles is completed, and the returnable case 1 is transported by being stacked in a container, for example, by a forklift or the like.

Now, the returnable case 1 can be disassembled into a compact storage state when the goods are transported and emptied. The method will be described.

[First stage of disassembling / storing] By removing the connection by the bolts 54 at all parts, the guard member 5 is removed and the frames 3 and 4 are left standing independently. The side frame 3 is removed from each steady rest patch 37, 38, and the bottom frame 7 is used as an axis to tilt the side frame 3 onto the skid 2, and the lower end of the corner strut 8 is placed on the plate portion 34a of the corner guide 35. . As described above, since the lower end portion of the corner strut 8 projects below the width of the foot material 31 of the skid 2, the bottom frame 7 is positioned inside the end steady rest patch 38 without interfering with the inner end steady rest patch 38. Therefore, the pair of long side frames 3 are overlapped 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 placed on the skid 2 by stacking them on the skid 2 with the bottom frame 19 side as an axis.

[Fourth stage of disassembling / storing] The returnable case 1 folded and stored thinly two-dimensionally (planarly) as described above is placed on the corner guide 35 as shown in FIGS. 4 and 5. Many are piled up by stacking, and many are stored in a small space.

According to the returnable case 1 of the present embodiment, the projections 27a at the four corners formed on the corner guide 27 above the short-side frame 4 are stacked at the time of assembly.
However, by being fitted into the fitting holes 31a at the four corners formed on the lower surface of the foot material 31 at both ends of the skid 2, the stacked state is favorably and stably maintained. Further, the protrusion 27a is fitted into the fitting hole 3
The configuration of fitting into 1a works effectively in the following cases.

As shown in FIG. 11, when the returnable case 60 having the same structure as the returnable case 1 of the above embodiment and having a length exactly twice is loaded on the returnable case 1 in which two returnable cases 1 are arranged side by side. When the returnable case 60 is placed in the center of the arranged returnable cases 1, there is nothing that interferes with the returnable case 60 and the returnable case 60 can be loaded. The returnable case 60 has a skid 61 and a long side frame 6.
2 and short side frame (not shown) has skid 6
1 and the corners of the upper end where the respective frames are joined are assembled using the same corner guide 63 as described above. If the configuration also includes a corner guide, the corner guide will be the skid 61.
It becomes impossible to load by hitting the header 64 of. However, in the returnable case 1 of this embodiment, the corner guide is not projected upward, and as a result, stacking on the top is possible. In addition, in the case of FIG. 11, the protrusion 2 is formed on the lower surface of the foot material 65 at both ends of the skid 61 of the returnable case 60 to be stacked on top.
A fitting hole that fits into 7a is formed.

According to the returnable case 1 of this embodiment, when the frame 4 is assembled, the bottom frame 19 is sandwiched between the central steady rest patch 37 and the end steady rest patch 38 which are arranged in a zigzag pattern. First of all, the center steady rest 37 is made wider than the width of the bottom frame 19, so that the short side frame 4 can be made to stand more stably and the assembling work is facilitated.

Furthermore, when disassembling and storing, especially when the long side frame 3 is laid down on the skid 2,
The lower end of the corner pillar 8 of the long side frame 3 is the skid 2
Since it protrudes below the width of the foot material 31, the bottom frame 7 is, as described above, the inner end steady rest patch 38.
It is located inside the end steady rest patch 38 without interfering with, so that the pair of long side frames 3 can be placed exactly on the surface of the deck plate 39 of the skid 2. Therefore, the returnable case 1 when stored does not have to be thick, and the size can be reduced when stored.

The returnable case 1 which constitutes each surface of the returnable case 1 at the time of assembly (top frame 6, 18, bottom frame 7, 19, corner support 8, 20 etc.) is a plate material covering the entire surface. Rather, it is a prismatic member and is hollow as described above, so that a significant weight reduction is also realized.

[0036]

As described above, according to the returnable case of the present invention, when the assembled state is stacked, the fitting portion on the lower surface of the skid is fitted into the protrusion of the frame in the assembled state, thereby making The effect is that the stacked state is favorably and stably maintained.

Further, in the case where the frame is constructed to have an upper frame, a bottom frame and a pair of columns that connect them in parallel to each other, at least one side of the four sides of the skid and at both ends and an intermediate part thereof. , Stabilizing patches that make the frame self-supporting are arranged in a zigzag pattern alternately on the outside and inside along the length direction of one side,
Furthermore, by projecting the lower end of the column below the bottom frame and setting the protruding length to be longer than the distance between the inner steady rest and the outer edge of the skid, the bottom frame is It is located inside the end baffle patch without interfering with the brace patch, which allows the frame to be placed snugly on the surface of the skid, which promotes compactness, and in addition, the brace patch placed in the middle part If the height of the frame is set higher than that of the bottom frame, the frame sandwiched between the steady rest patches at both ends and the middle part can be stably made to stand, and the assembling or disassembling work becomes easy.
