Description

[Detailed Description of the Invention] The present invention relates to a device for pivoting side panels together in a box body for an assembly type storage box that can be folded extremely compactly.

Conventionally, collapsible storage boxes that can be folded into a small size and are convenient to carry have been provided, but many of these types of storage boxes do not allow the folded state to overlap tightly. Since it is not possible to store a large number of units, it has the disadvantage of requiring a large space to store a large number of units.

The present invention aims to eliminate such drawbacks, and its structure will now be described in detail with reference to an embodiment shown in the accompanying drawings.

In a box body for an assembled storage box that can be folded into two layers by pivoting the four side plates 1, 2, 3, and 4 to each other at adjacent sides, the two side plates 1, 2 are A plurality of joint shaft cylinders 5 are provided on adjacent sides so as to fit between the respective extended surfaces of the inner and outer side surfaces of the side plates 1, 2, 3, and 4, and in a state in which adjacent ones are engaged with each other in multiple stages. Shaft rod 10 of comrade jointed shaft cylinder 5
Two connecting side plates a and b are formed by inserting the two side plates 1 and 2 in a bendable manner, and attaching shaft cylinder mounting portions 7 to both ends of the connecting side plates a and b. 2,
Side plates 1, 4 are fitted between the extension surfaces of the inner and outer side surfaces of 3 and 4, and the opposing inner surfaces are respectively
2, 3, 4 are provided on the inclined surfaces 8 that are inclined with respect to the inner surfaces, and a plurality of joint shaft tubes 9 are provided on the inclined surfaces 8 of the opposing shaft tube mounting portions 7, respectively, in a state in which adjacent ones are engaged with each other in multiple stages, A shaft rod 10 is attached to this adjacent joint shaft cylinder 9.
This invention relates to a pivoting device for side plates in a box body for an assembly type storage box, characterized in that two sets of connecting side plates a and b are connected by passing through the body.

In addition, in the drawing, a support bar 1 is provided at the inner lower edge of each side plate 1, 2, 3, 4 in order to support the bottom plate 11.
A side plate 1 with a protruding portion 1′ and a folded bottom plate 11,
In order to store the space between 2, 3, and 4, the bottom plate 11 is made up of two divided plates, and a storage recess 12 for storing each of the divided plates is provided on each side plate 1,
The figure shows a case in which it is formed on the inner side of parts 2, 3, and 4.

Symbols 13, 14, 15, 16 in the figure are each side plate 1,
2, 3, and 4, and the side plates 1,
The inner and outer sides of 2, 3, and 4 are reinforced with these reinforcing rods 13 and 1.
It is determined by the innermost and outermost edges of 4, 15, and 16.

Since the present invention is constructed as described above, in order to assemble this storage box, the vicinity of the shaft attachment part between the joint shaft cylinder 9 and shaft rod 10 of each connecting side plate a, b is pushed inwardly by hand. If the two side plates 1 and 3 and the two side plates 2 and 4 that make up each of the connecting side plates a and b are pulled apart until they form a right angle, the joint shaft cylinder 9 and the shaft rod will be separated. 10 is bent at a right angle, and the shaft attachment portions formed by the joint shaft cylinder 5 and shaft rod 6 of each of the side plates 1, 2 and 3, 4 are bent at a right angle to form four side plates. 1, 2, 3, and 4 are assembled into a box body arranged on the front, rear, left, and right sides.

Thereafter, by fitting the bottom plate 11, a box assembly type storage box is formed.

In this case, the joint shaft cylinder 5 and the joint shaft cylinder 9 are attached to the sides of each side plate 1, 2, 3, 4 in a state in which the adjacent shaft cylinders 5 and 9 are engaged with each other in multiple stages, and on the inner and outer sides of the side plates 1, 2, 3, 4. Since the shaft rods 6 and 10 are inserted between the joint shaft tubes 5 and 9 which are fitted in multiple stages and are fitted between the respective extension surfaces, no gaps are formed in these shaft joints. , and also each side plate 1, 2, 3,
Since the joint shaft cylinder 5 and the joint cylinder 9 do not protrude from the inner surface of the cylinder 4, it is extremely easy to use.

When folding it in the opposite direction, raise the bottom plate 11, and then manually spread the vicinity of the shaft attachment part between the joint shaft tube 9 and the shaft rod 10 of each connecting side plate a, b outward from each other. When the side plates 1, 3 and 2, 4 that make up the The folding work is completed when the two sheets are stacked one on top of the other.

In this case, since the joint shaft cylinder 9 and the bearing mounting part 7 are arranged to fit between the extension surfaces of the inner and outer sides of the side plates 1, 2, 3, and 4, the connecting side plates a, which are folded in two layers, There is no gap between the two connecting side plates a and b since the joint shaft cylinder 9 is provided on the inclined surface 8 formed on the opposite inner side of the bearing mounting part 7.
can be folded into an extremely compact rectangular plate shape, making it convenient to carry, and when not in use, the bottom plate can be removed and stored side by side or stacked.

In this way, the present invention can be easily assembled and folded, and the folded shape is an extremely compact rectangular plate with no gaps or irregularities, making it convenient to handle. This provides an effective pivoting device for attaching side plates to each other in a box body for an assembled storage box.
