Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage box made of a metal plate.

[0002]

2. Description of the Related Art Conventionally, for example, a tool storage box of a truck is fixed to an outer portion of a vehicle body in order to make maximum use of a carrier. That is, unlike a passenger car, it is detachably fixed to the vehicle body in a state of being exposed to the outside. For this reason, the storage box is provided with a certain degree of strength so that the storage box is not deformed or damaged even when a slight impact is applied from the outside.

[0003] When a storage box is made by combining a plurality of metal plates, it is common to manufacture by fixing the metal plates with bolts and nuts or welding.

[0004]

However, in a storage box made by fixing a metal plate with bolts, nuts, welding, or the like, the number of fixing points is large and the manufacturing cost is increased. There was a problem that the box would not look good because it would be visible. Furthermore, since the edge of the metal plate appears on the inner surface or the outer surface, there is a problem that the edge must be deburred.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a storage box which is easy to manufacture even if made from a metal plate and has a good appearance.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, an object of the present invention is to form an opening on one side for taking in and out of articles, a back plate opposite to the opening, side plates on both left and right sides, and both sides. In a storage box having a top plate and a bottom plate that are hung on a plate, the back plate has an outer back plate and an inner back plate, the left and right side plates have outer side plates and an inner side plate, respectively, and a back plate in the outer side plate. A double-folded edge formed by bending twice is formed on the joint side of the above, a bent-edge is formed on the outer back plate to abut against an outer surface side of the double-folded edge, and the inner back plate is formed with a bent edge. A bent edge whose inner surface abuts on the inner surface side with the double bent edge and an insertion groove provided near the bend are formed, and an insertion piece inserted into the insertion groove of the inner back plate is formed on the inner side plate. The insertion piece is attached to the outer back plate. It is characterized by being plugged Ri bending in contact with the inner edge.

The present invention is advantageous in that the top plate and the outer bottom plate are detachably attached to a connected body of the back plate formed by inserting the insertion piece of the inner side plate and the left and right side plates. It is a target.

Further, the present invention is effective when an inner bottom plate for supporting an inner side plate is detachably attached to a box structure in which the top plate and the outer bottom plate are attached to the connecting body.

Furthermore, the present invention is effective when a cover for covering the opening is attached to the bottom plate. Still further, according to the present invention, the outer bottom plate and the top plate attached to the back plate are provided with a connecting piece inserted from a rear side into a connecting hole of the outer back plate, and the connecting piece is provided between the outer side plate and the inner side. It is effective if located between the plates.

Still further, the present invention is effective when the inner side plate is formed with connecting pieces which are sequentially inserted into the connecting holes of the outer bottom plate and the top plate and the connecting holes of the outer side plate.
