Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container used for transporting, transporting, storing, etc. various articles, and particularly to a collapsible container.

[Prior art]

Traditionally, the first collapsible container
A structure as shown in Fig. 0 is known. In other words, in the figure, 11 is the frame, 12 is the bottom plate, 1
3 is a side plate consisting of an upper plate-like portion 14 and a lower plate-like portion 15. This side plate 13 is connected so that both plate-like parts 14 and 15 can be bent at a connecting part 16. The upper plate-shaped portion 14 of this side plate 13 is rotatably attached to the frame 11 by a mounting shaft 17, and the lower plate-shaped portion 15 is rotatably mounted to the bottom plate 12 by a mounting shaft 18. It is installed so that it can be moved. Therefore, if this connecting portion 16 is extended, both the upper and lower plate-like portions 1 of the side plate 13
4 and 15 are straight and have a flat shape,
It can be folded by bending from this connecting portion 16. Reference numeral 19 denotes a tilting plate attached to the frame 11 so that one edge thereof can be rotated by a mounting shaft 20.

The conventional folding container shown in FIG. 10 is assembled by extending the side plates 13 and then erecting the flap plates 19. After assembly, the side plates 13 are prevented from bending from the connecting portions 16 by the side plates 19, so that the side plates 13 are maintained in the assembled state.

On the other hand, if the side plate 13 is bent at the connecting portion 16 after tilting the tilting plate 19 toward the frame 11, it can be brought into a folded state.

Conventional collapsible containers having the structure described above cannot be increased in height (depth) when assembled. In order to increase the height, the gate plate 19 etc. must be made taller, but when increasing the height of the gate plate, etc., the maximum height should be the length of the long side of the frame, and the specified dimensions should be met. In addition, if the long sides of the frame are lengthened to make it foldable, the overall size of the container increases, making it difficult to transport it manually. Therefore, there was a certain limit to the height when the container was assembled.

[Structure of the invention]

The folding container of the present invention includes at least one intermediate frame disposed between the frame and the bottom plate,
The frame and the intermediate frame and between the intermediate frame and the bottom plate (or between each intermediate frame if multiple intermediate frames are arranged) are connected by bendable side plates and tilting plates, thereby connecting the upper stage above the intermediate frame. The height when assembled is a two-tiered structure in which the lower section and the lower part of the intermediate frame are each foldable, or in the case where multiple intermediate frames are provided, the space between the intermediate frames is also foldable and has three or more tiers. It is designed to have a large depth.

〔Example〕

Figures 1 and 2 are views showing an embodiment of the multi-tiered folding container of the present invention. Figure 1 is a perspective view of the assembled container, and Figure 2 is a perspective view of the folded container. FIG.

In FIG. 1, 1 is an intermediate frame, 2 is an upper part, and 3 is a lower part, the upper part being a frame 11, a side plate 13 consisting of an upper plate part 14 and a lower plate part 15,
It consists of a tilt plate 19, an intermediate frame 1, etc. Further, the lower section is made up of an intermediate frame 1, side plates 13, gate plates 19, bottom plate 12, and the like. Both the upper part 2 and the lower part 3 can be folded up by folding down the flap plate 19 and bending the side plate 13 at the connecting part 16, similar to the container shown in FIG. 10, so that they can be stored or carried as shown in FIG. Easy to compact.

3 to 6 are diagrams showing the structure of the intermediate frame 1. Among these figures, FIG. 3 is a view seen from above (top view), FIG. 4 is a view seen from below (bottom view), and FIG. 5
6 are sectional views taken along the - line and - line in FIG. 3, respectively.

As shown in these figures, the intermediate frame 1 is a rectangular frame similar to the frame shown in FIG. 10, and a support portion 4 having a constant width is provided on the inner surface thereof over the entire circumference. A lower plate-shaped portion of the side plate of the upper stage is attached to the upper side of the support part 4, and when the upper stage is assembled, the side plate and the gate plate are positioned on the support part 4 and support them. That is, attachment parts 5 and 6 are formed in the upper part of the support part 4, and these attachment parts 5.
The mounting portion 15a of the lower plate-like portion 15 of the side plate is inserted into the grooves 5a, 6a of No. 6 as shown by chain lines,
Rotatably mounted on a shaft. The mounting part 5 provided in the middle part of these mounting parts has a shape as shown in FIG. After inserting the shaft 15a into the groove 5a, the shaft is passed through from the right side of the drawing, and heat is applied to the portion 5b of the mounting portion 5 to deform or weld the shaft to prevent the shaft from coming off.

As described above, the upper plate-shaped portion of the side plate and the gate plate are attached to the frame, and the lower plate-shaped portion of the side plate is attached to the intermediate frame to form the upper stage portion. The claws 7 provided on the left and right sides of the intermediate frame 1 are shown in Figs. 3 and 8 (Fig. 3).
It has a structure as shown in the enlarged sectional view taken along the line (-) in the figure, and is designed to fit into the lower end of the gate plate when it is erected during assembly.

Next, on the lower side of the support part 4, in order to increase the strength of the intermediate frame 1, a wall plate is further provided inside the intermediate frame 1 to form a double structure, and a rib 8 is further provided in between. This support part 4
A mounting portion 9 is also provided on the lower side of the mount 9, to which the upper plate-shaped portion of the side plate is rotatably mounted by the same means. Further, the lower tier plate is rotatably mounted through the shaft hole 10 shown in FIG. 9 (an enlarged sectional view taken along the line - in FIG. 3).

In this manner, the side plates and the tilt plate are attached to the lower side of the support portion 4 of the intermediate frame 1, and the bottom plate is attached to the lower plate-shaped portion of the side plate, thereby forming the lower stage portion 3. Therefore, the lower section can be assembled by stretching out the bent portions of the side plates and erecting the gate plates.

In this way, the intermediate frame 1 has the structure shown in the figure, and the upper part is connected to the upper part of the frame, the side plates, and the tilt plate, and the lower part is connected to the lower part, which is made of the side plates and the bottom plate of the tilt plate. So, the upper part,
A container can be constructed by assembling the lower part. In this case, the container will have side walls formed by the upper and lower side plates and the intermediate frame, and by the upper and lower flap plates and the intermediate frame, respectively, and will be twice as tall as the conventional folding container. Moreover, if the upper and lower parts are folded, a compact shape as shown in FIG. 2 is obtained. Moreover, since there is no need to increase the outer circumferential dimensions of the frame, intermediate frame, etc., the device can be made large enough to be held not only when folded but also when assembled.

In the embodiment shown in FIG. 1, the heights of the upper and lower parts are the same, but it is also possible to make them different heights. However, if the heights of the upper and lower parts are made equal, it is convenient because the side plates and the flap plates can be molded using a common mold for the upper and lower parts.

In the above embodiments, the structure is such that only the upper part can be assembled and used while the lower part remains folded, or it is possible to use appropriate parts to hold the lower part in the folded state. In this way, it is possible to use both the upper and lower parts as a deep container by assembling them, or to use only the upper part as a normal deep container.

Although the description so far has been made regarding a two-tiered container, it is also possible to use two or more intermediate frames of the structure shown in the drawings to form a container with three or more tiers.
For example, using two intermediate frames, attach the upper plate member of the middle side plate to the upper intermediate frame, the lower plate member to the lower intermediate frame, and then attach the tilt plate to the upper intermediate frame. .

Incidentally, the support section 4 may have a structure in which only the ribs 8 support the side plates and the gate plate of the upper stage without providing the part shown by 4a in FIGS. 5 and 6.

〔Effect of the invention〕

The folding container of the present invention has a structure that can be folded by making it multi-tiered, and the height can be increased without increasing the outer circumference of the frame, etc., and tall products can be easily accommodated. be.
Moreover, since it has sufficient strength, it can be stacked. Furthermore, by fixing the lower part using appropriate parts, it becomes possible to use only the upper part, and it becomes possible to use it according to the shape and size of the product to be accommodated.
