Description

[Detailed Description of the Invention] The present invention relates to a container used for transporting and transporting various articles, and particularly to a collapsible container.

Conventionally, containers of this type are known to be container-shaped that cannot be folded or have a structure in which each part can be separated, but containers that cannot be disassembled have a large volume when not in use. This has the disadvantage that it takes up a lot of space when stored.

Moreover, those having a structure in which each part can be separated have problems such as being troublesome to assemble.

The present invention was developed in view of the above circumstances, and is foldable and extremely easy to assemble.
Furthermore, the present invention provides a folding container that solves the problem of weakening of strength that may occur due to the folding type.

The details of the folding container of the present invention will be explained below based on the drawings.

Fig. 1 is a perspective view showing the entire container, and 1 is a frame, 2 is a bottom plate, and 3 is a side plate, which consists of an upper plate-like part 4 and a lower plate-like part 5, and these parts are connected. The parts 6 are connected so as to be bent at this part.

The upper plate-like portion 4 of the side plate 3 is rotatably attached to the frame 1 by a mounting shaft 7, and the other lower plate-like portion 5 is rotatably mounted to the bottom plate 2 by a mounting shaft 8. It is installed so that it can be moved.

Therefore, if this connecting portion 6 is extended, both the upper and lower plate-like portions 4 and 5 of the side plate 3 become straight in one plane, and if they are bent from this connecting portion 6, they can be folded.

Reference numeral 9 denotes a gate plate attached to the frame 1 so that one edge thereof can be rotated by a mounting shaft 10.

After the side plate 3 is stretched out, this tilting plate 9
The container is assembled by standing it up, and conversely, by folding the flap plate 9 toward the frame 1 and folding the side plate 3 at its connecting portion 6, the container is folded.

Next, the more specific structure of each part of the folding container of the present invention will be explained.

First, to explain the structure of the side plate 3, on the side of the connecting part 6 of the lower plate-like part 5, as shown in FIG. 2A, there are hook-shaped protrusions having a cross-sectional shape as shown in FIG. Several portions 5a are provided.

On the other hand, the above-mentioned protrusion 5 is provided on the connecting portion 6 side of the upper plate-like portion 4.
A recess 4a is formed at a position opposite to a.

That is, when the side plate 3 is folded, the protrusion 5a is located at the position shown by the chain line in FIG. 2B, and when the side plate 3 is extended, the protrusion 5a is located at the position shown by the solid line. In this state, the protruding portion 5a is fitted into the four portions 4a.

Similarly, the upper plate-like portion 4 also has a protruding portion 4b, and the lower plate-like portion 5 has four portions 5b formed at corresponding positions, and these are the second protrusions when the side plate 3 is extended. It is fitted exactly as shown in Figure B.

Further, another protrusion 4C having a similar shape is formed on the side plate 3.
As shown in FIG. 3, a recess 9a into which the protrusion 4C fits
It is formed on the gate plate 9.

Also, a hole or recess 9b is formed in the lower part of the tilting plate 9, and this part is configured to exactly engage with three claws 2C, 2d, and 2e arranged on the bottom plate 2 with slight vertical shifts. ing.

That is, when the tilting plate 9 is moved vertically, the part indicated by reference numeral 9C is below the pawl 2C provided on the bottom plate 2, and the parts indicated by reference numerals 9d and 9e are respectively attached to the pawl 2d.
, 2e.

Further, a gripping hole 9f is formed in the upper part of the tilting plate 9.

Reference numeral 11 denotes a pin attached to the lower part of the gate plate 9 so as to be able to move up and down within a certain range.When the gate plate 9 is stood upright, it is inserted into the small hole 2a formed in the bottom plate 2, and forms a stopper for these pins. However, this prevents the tilting plate 9 from moving relative to the bottom plate 2.

Further, reference numeral 12 denotes a fork-like member with a spring-like tip 12a, which is inserted into the groove 13 of the shape shown in FIG. 3 provided in the frame 1 when the container is folded as shown in FIG. The spring-like member 12 is inserted while its tip 12a is narrowed by the groove 13, whereby the frame 1 and the bottom plate 2 can be made immovable, and these constitute a stopper.

Furthermore, an appropriate number of holes 5C are formed at appropriate locations on the lower end surface of the plate-like portion 5 on the lower side of the side plate 3, and the holes 5C in the bottom plate 2 are formed at appropriate locations.
A hook-shaped protrusion 2f is provided at a position in contact with.

These parts are enlarged in FIG. 5, and when the side plate 3 is stretched straight and the lower plate-shaped part 5 is stood up at almost a right angle to the bottom plate 2, the bottom plate 2 becomes The bar-shaped protrusion 2f serves to fix the lower plate-shaped portion 5.

In FIG. 5, A is a view from outside the container, and B is a view from inside the container.

Next, a method for assembling and folding the folding container of the present invention will be explained.

First, when assembling, as shown in FIG. 1, the side plate 3 is stretched out so that the upper plate part 4 and the lower plate part 5 are on the same plane, and then the gate plate 9 is erected.

If this tilting plate 9 is made vertical, the tip of the pin 11 (it is more preferable to have a curved surface) as described above.
When the pin 11 reaches the position of the small hole 2a of the bottom plate 2, the pin 11 is inserted into the small hole 2a by its own weight, and as a result, the gate plate 9 becomes immovable relative to the bottom plate 2.

In this case, the side plates 3 are prevented from being bent inward by the flap plates 9, so that the container is maintained in the assembled state.

On the other hand, when folding an assembled container, first turn the container upside down.

As a result, the pin moves due to its own weight and is dislodged from the hole 2a, allowing the tilting plate to move.

Now, by folding the fan plate so that it is almost horizontal, the side plate 3, which could not be moved due to being obstructed by the fan plate 9, can be folded at its connecting part 6.
It is sufficient to fold the frame 1 and the bottom plate 2 until they overlap. In this case, the frame 1 and the bottom plate 2 are fixed by a stopper constituted by the spring-like member 12 and the structure 13 as described above.

As explained above, the folding container of the present invention is easy to assemble and fold, and when assembled, the plurality of pairs of protrusions and recesses formed on the upper and lower plate-like parts of the side plates fit together. In this way, the strength of the folds (connections), which are the weakest parts of foldable products, is increased.

In particular, this connecting part prevents it from falling outward.
There is no risk that this connection will bend outward when the container is filled with items.

Further, the structure includes another protrusion 4C and a recess 9a formed in the flap plate to similarly prevent the side plate 3 from bending outward, thereby further increasing the strength of the side plate.

In addition, the bottom plate 2 is provided with claws 2C, 2d, and 2e, and the opening plate 9 is also provided with a hole 9b having the shape shown in the figure, so that the bottom plate 2 is supported by the opening plate 9, and items can be placed therein. This prevents the bottom plate 2 from bending when

Similarly, the hook-shaped protrusion 2f of the bottom plate 2 also prevents the bottom plate from bending.

Since the container has a structure with high strength when assembled, even if it is made of synthetic resin material, a container with sufficient strength can be constructed.

Furthermore, if the frame 1 is provided with a groove 13 and the bottom plate 2 is provided with a spring-like member 12, the frame 1 and the bottom plate 2 are fixed together when the container is folded, making it convenient to carry. There is a hole 9f for gripping on the tilting plate 9 so that the grip can be easily held.
