Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a peripheral wall structure of a box used as a container for freight transportation.

[Conventional technology]

As the above box, there is a conventional box shown in FIG. This one is composed of opposite side walls a, a and front and rear walls b, b and a bottom plate c.
The box main body A is constituted by the above, and the lid B constituted by the peripheral frame d and the top plate e is provided on the upper surface thereof.

The conventional box configured in this way is required to be fairly sturdy for the purpose of use, and thus is made of, for example, a material such as aluminum or duralumin. Has been riveted to.

[Problems to be solved by the device]

However, the above-mentioned conventional box has the following inconveniences during manufacture and use.

First, assembling work using rivets requires skill and is difficult to disassemble after assembling.

Therefore, storage when not in use is bulky.

In addition, it is preferable that this type of box is according to the height of the object to be transported because the fare is reduced, but since the height of the box body cannot be adjusted according to the above box, it is larger than the object to be transported. If you use a box, the freight cost will be higher.

Furthermore, if a plurality of boxes of various sizes are prepared according to the size of the object to be transported, the cost will increase and the storage when not in use will also increase.

Therefore, this device can be easily disassembled and assembled without requiring skill, and the depth (height) can be adjusted.
Another object of the present invention is to provide a box peripheral wall structure that does not become bulky if stored in a disassembled state.

[Means for Solving the Problems]

In order to solve the above problems, in the present invention, a box 1 in which a plurality of square frames 3 are vertically stacked to form a peripheral wall
In the above, the square frame 3 is composed of a pipe frame 6 having a substantially rectangular cross section forming each side thereof, and a connecting tool 8 for connecting the respective frames 6 to each other. Providing a ridge 10 in the length direction, a recess 11 into which the ridge 10 is fitted is provided on the other surface along the length direction,
The ridge 10 has a rib 10a that extends laterally along the entire length of the tip edge.
In addition, the recess 11 has a groove 11a into which the rib 10a fits along the entire length of the inner surface thereof, while the connector 8 is divided into two parts by the bisector of the corner of the square frame 3. Cage,
The divided pieces each have a support portion 12 fitted into the end opening of each frame at one end, and a bulge portion 8a is formed on the other end side where the divided pieces are overlapped. The cover body 13 extending in the up-down direction is fitted into the overlapped bulged portion 8a.

[Action]

In the box of the present invention configured as described above, each wall of the peripheral wall is formed by each frame at the time of assembling, and then each wall is connected by the connecting tool. In the configuration, the number of frames corresponding to the required height is selected, and one rib of the upper and lower frames is fitted in the other groove, and the ridge having the rib is pushed into the recess of the other frame. Combine frames. This action is performed between all the frames to form the peripheral wall.

On the other hand, at the open end of each frame of the peripheral wall, the support portion of the split piece of the connecting tool is fitted and supported to overlap the pair of split pieces, and the cover body is fitted to the bulging portion. By this fitting, the divided pieces are integrated, and the walls are integrated via a connecting tool made of the divided pieces to form a peripheral wall. That is, the peripheral wall is reliably connected by the cover body via the connecting tool.
