BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large collapsible container used for storing items such as beer and soft drinks, draft beer barrels, and moving luggage.

[0002]

2. Description of the Related Art As a conventional folding container, there is one disclosed in Japanese Utility Model Publication No. 55-36346. As shown in FIG. 18, four side wall plates b, c, d, and e are rotatably connected to the lower end of four side wall plates b, c, d, and e on the four circumferences of the bottom plate a. I am doing it. Then, the side walls b, c, d, and e are erected, and adjacent side wall plates are connected by a connecting tool f to retain the shape.

[0003]

[Problems to be Solved by the Invention] In the case of such a conventional example,
The side walls adjacent to each other are connected by a connecting tool f to maintain the shape,
Since all the connecting tools f are covered by the outer surface side and connected, there is a problem in that a large container cannot be assembled by one person. That is, in the case of a large container, since the side walls b, c, d, and e are heavy in weight, they cannot be assembled unless they are placed on the bottom plate a and stand side by side.
According to the conventional structure, one operator must ride on the bottom plate a to stand up the side wall plate, and the other operator must operate the connector outside the bottom plate a to connect. There is a problem that it takes manpower to assemble. Further, there is a problem that the operation of connecting with the connecting tool cannot be easily performed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a folding container that can be easily assembled even with a large container by a small number of human hands and can surely retain its shape. There is.

Next, the operation of the folding container A constructed as described above will be described. It is used to store and transport articles by assembling the folding container A into a rectangular box shape. The assembling is performed as follows. First, the left and right side wall plates 2c, 2 with respect to the bottom plate 1
d is raised vertically. At this time, the side wall plates 2c and 2d
When standing up, the side wall plates 2c and 2d are self-supporting so as not to fall down. Then, the side wall plate 2b is erected on the bottom plate 1 and the engagement step portion 16 and the engaged step portion 17 are engaged with each other. At this time, the engaging claw 11 and the engaging hole 14 of the engaging means B are engaged with each other to be engaged and connected, and the slide lock tool 20 of the locking means C is operated to be locked. At this time, the bottom plate 1
The slide lock 20 is locked by sliding the slide lock 20 from the inner surface of the side wall plate 2b while riding on the top. Next, the support wall portion 1 of the front side wall plate 2a, which is located in front of the bottom plate 1, is provided.
0 is raised. Also at this time, the engaging claw 11 and the engaging hole 14 of the engaging means B are engaged and engaged and the slide lock tool 20 of the locking means C is operated to be locked.
Then, the front upper door 5a and the lower front door 5b, which are two folds of the front door wall portion 5, are expanded and erected. Also at this time, the engaging claw 11 and the engaging hole 14 of the engaging means B are engaged and engaged and the slide lock tool 20 of the locking means C is operated to be locked. The bottom plate 1 is locked by the locking means C.
This is performed by sliding the slide lock tool 20 from the outer surface in front of.

In this way, the articles are stored in the assembled state of the folding container A. If necessary, the fork of the forklift is inserted into the fork insertion portion 7 and moved to the place for storing the articles by the forklift. In a place for storing articles, as shown in FIG. 8, the front upper door 5a and the front lower door 5b are tilted outward and folded in half to open the front opening, or the front upper door 5a is opened as shown in an imaginary line in FIG. It is also possible to open the front opening by tilting down only the top of the front lower door 5b. At this time, since there is the support wall portion 10, the side wall plates 2c and 2d are held so as not to spread even if the front upper door 5 and the front lower door 5b are tilted and folded in half as shown by the solid line in FIG. Articles are stored inside with the front opening opened, and the front upper door 5a and the front lower door 5b are erected to close the front opening. Then, the fork of the forklift is inserted into the fork insertion portion 7, and the folding container A storing the articles is moved by the forklift,
It is loaded on trucks and transported.

When articles are not stored in the folding container A, they are folded as follows. First, as shown in FIG. 9, the lock means C is unlocked, the upper front door 5a and the lower front door 5b are folded in two, and they are folded inward and stacked on the bottom plate 1, and the support wall portion 10 is the bottom plate. Stacked on top of 1. Next, the lock of the locking means C is released, and the side wall plate 2b on the back side is tilted down so that the side wall plate 2b is overlaid on the front upper door 5a, as shown in FIG. At this time, the rising wall 8
At the center of rotation of the side wall plate 2b, the upper front door 5a and the lower front door 5 are
Since the thickness is increased by the sum of the thickness of b, the side wall plate 2b is tilted so as to be parallel to the bottom plate 1. Next, the left and right side wall plates 2
One of the side walls 2c of c and 2d is laid down on the side wall 2b. Also at this time, the rotation center of the side wall plate 2c is higher than the rotation center of the side wall plate 2b on the rising wall 9.
Since the thickness of b is high, the side wall plates 2c are stacked horizontally. Next, as shown in FIG. 11 and FIG. 12, the other side wall plate 2d is tilted down to stack the side wall plate 2d on the side wall plate 2c. At this time, the shaft 4 of the side wall plate 2d moves upward along the long hole 3 and the center of rotation moves upward, so that the side wall plate 2d is placed on the side wall plate 2c in parallel with the bottom plate 1.
When the side wall plates 2c and 2d are folded and folded, the rotation centers of both the left and right side wall plates 2c and 2d can be moved up and down in the elongated holes 3, so that the side wall plate 2d is first pushed down and then the side wall plate 2c is moved. Even if it is tilted, it can be folded so that the side wall plates 2c and 2d are parallel to the bottom plate 1. That is, the side wall plates 2c and 2d
It can be folded in the same manner when any one of them is pushed down first. The folding container A thus folded is shown in FIG.
As shown in FIG. 3, a large number are loaded and stored or transported.
