Description

[Detailed explanation of the idea] This proposal concerns a collapsible container.

The present invention seeks to provide a simple and inexpensive container that can be easily assembled and folded.

The present invention will be explained below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a rectangular bottom plate, the peripheral edge of which is an upright edge 11, and both sides 11a of the upright edge 11.

Inward protruding pieces 13 a and 13 b are protruded from appropriate positions of 11 b, and the front and rear sides are formed into a pair of inwardly directed guide rails 12 a and 12 b with a U-shaped cross section. .

Reference numeral 2 denotes a rectangular frame having substantially the same shape as the outline of the bottom plate 1, and has a bow-shaped cross section.

Reference numerals 3a and 3b denote left and right side plates, which are suspended from the left and right sides 21a and 21b of the frame 2 through pivot joints 4a and 4b, and have step portions 32a and 32b on the outer edge of the lower end. Sliding protrusions 31 a, 31 a, 31 b on the sides,
31 b protrudes and connects it to the guide rail 12 a.
, 12b.

5a and 5b are a front plate and a rear plate, which are the front side part 2 of the frame 2.
The guide rail 1 is suspended from the rear side 22a and the rear side 22b by a pivot 6a, and has a width that fits between the inner surfaces of the vertical side plates 3a and 3b.
Engagement tongue piece 51 a that engages with the inside of 2 a and 12 b
, 51 a, 51 b, and 51 b.

Therefore, when assembling, first, the frame 2 is pulled up.

Then, the sliding protrusions 31a, 31 of both side plates 3a, 3b
a, 31 b, 31 b are guide rails 12 a,
12 b, both side plates 3a and 3b are in a vertical state, and the lower outer edges of both side plates are on both sides 1 of the bottom plate upright edge 11.
1 all b Abuts against the inner surface, and the step 3 on the outer edge of the lower end
2a.

32b engages with the inward projecting pieces 13a, 13b of the raised edge side portions 11a, 11b.

Next, the front plate 5a and the rear plate 5b are pushed from the inside to make them vertical, and are fitted between the inner surfaces of the side edges of the vertical inner plates 3a and 3b, respectively, and the lower ends are attached to the guide rails 12a, 1.
2 b Abutting against, engaging tongue pieces 51a, 51a, 51
b, 51 b as force id 1/-/l/12 a, 12
b.

This results in the assembled state shown in FIG.

When folding, perform the reverse operation to assemble, and
, fold back plate 5b and side plates 3a, 3b inward, lower frame 2, fold side plates 3a, 3b down, and fold front plate 5a and rear plate 5b thereon. , fold as shown in FIG.

It should be noted that each of the above members is molded from a suitable synthetic resin.

According to the present invention, it can be assembled and folded extremely easily by raising and lowering the frame body 2, and no special supporting metal fittings, springs, etc. are required for assembly, and the structure can be provided simply and inexpensively.

Further, the side plates 3a, 3b, the front plate 5a, and the rear plate 5b are suspended from the frame 2 by pivoting, and therefore, even without a spring or the like, their own weight acts effectively to support the frame 2. As it is pulled up, it is automatically assembled smoothly and without any danger, and in the assembled state, both side plates 3a and 3b are supported by the front plate 5a and rear plate 5b and folded inward. Moreover, since the front plate and the rear plate are in a hanging state, they do not easily bend inward due to the action of their own weight and engagement friction. responds strongly to external forces, so
The assembled form can be firmly maintained.

Furthermore, in the folded state, it becomes flat with no wasted space, which is convenient because it does not take up much space for storage or transportation.

It is not only used for transportation, but has various other uses, and is extremely useful in practice.
