Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bottom plate joining device for an assembly type organizer box that can be folded into a small size, and its structure will be described in detail with reference to the accompanying drawings as follows.

In the assembly type organizing box in which a box body 4 is formed by assembling a bottom plate 1, left and right side plates 2, 2, and front and rear side plates 3, 3, the bottom plate 1 is divided into two to form two bottom half plates 1a and 1b. The ones in the drawing are the respective bottom half plates 1a and 1b.
The lower edges of the left and right side plates 2, 2 are connected to the outer edges of the bottom half plates 1a, 1b with plastic hinges 5, and fitting protrusions 6 are provided on the front and rear edges of the bottom half plates 1a, 1b and the left and right side plates 2, 2,
This figure shows a configuration in which each fitting protrusion 6 is assembled into the box body 4 shown in FIG. However, it is the same even if the present invention is applied to an assembly type organizing box with other configurations, and the bottom half plate 1 in the drawing
Although a and 1b show the case of a point symmetrical structure with good productivity, the same effect can be obtained even if the bottom plate 1 is divided asymmetrically.

A joint concave edge 8 is left on the inner edge of each of the bottom half plates 1a, 1b, and a joint flange 10 is formed in which several fitting holes 9 are bored on the upper surface.

The drawings show a case where the width of the joint concave edge 8 and the width of the joint protrusion 10 are formed to be the same width for good productivity. The other joint protrusion 1 is attached to the upper peripheral edge of the joint concave edge 8.
A joint plate 11 that is fitted onto the plate 1 is provided in a protruding manner.

A protrusion 13 that fits into the other fitting hole 9 is vertically provided on the lower surface of this joint plate 11.

In the drawing, two fitting holes 9 are formed on the upper surface of the joint flange 10, and two protrusions 13 corresponding to these are formed.
This figure shows a case in which the joint board 11 is vertically installed on the lower surface of the joint board 11.

In the figure, reference numeral 14 indicates a retaining protrusion, and reference numeral 15 indicates a retaining protrusion 14.
12 is a handle.

In general, prefabricated sorting boxes are made with the main purpose of being folded compactly to make them more convenient to transport and carry, but in order to increase the internal volume while giving stability to the box, the bottom plate area is If the size was increased, the area of the bottom plate would be increased and the volume in the folded state would increase, resulting in disadvantages such as inconvenience in transportation.

The present invention eliminates such drawbacks, and since it is constructed as described above, the joint concave edge 8 of one bottom half plate 1a is connected to the joint ridge 10 of the other bottom half plate 1b as shown in FIG. If the two bottom half plates 1a and 1b are joined by the protrusions 13, facing each other and fitting the protrusions 13 into the fitting holes 9 as shown in FIGS. The joint plate 11 of the bottom half plate 1a that is joined together and one of the bottom half plates 1a
Since the bottom surface of the bottom plate suppresses the top surface of the joint flange 10 of the other bottom half plate 1b, the overall appearance of the bottom plate 1 is improved, and the joint condition is also improved because the protrusion 13 provided in the vertical direction Since it fits into the fitting hole 9 that is also drilled in the vertical direction, there are two bottom halves 1a and 1b.
The bottom plate becomes firm and durable without separating.

In addition, since the bottom plate 1 is divided into two parts, the volume in the folded state can be more compact than that of the conventional single-plate bottom plate 1. For example,
To enable stable and easy-to-use items with a large bottom area to be folded into a small area convenient for carrying and transportation.

If this invention is applied to the bottom of an assembly-type organizing box, it will have many excellent practical effects, such as being able to be folded into a small size, having a large bottom surface after assembly, making it easy to use, and providing a large-capacity organizing box. do.
