BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal assembly box used for various purposes such as transportation, storage and temporary storage of articles.

[0002]

2. Description of the Related Art In the above-mentioned assembling box, a side plate and a bottom plate are separately manufactured, and these are assembled and joined by any joining means. For example, Japanese Patent Application Laid-Open No. 4-44948 discloses a structure in which a side plate vertically divided at a corner portion is joined to a tray-like bottom plate so as to be able to fall down by a hinge structure, and the side plates are joined by a locking projection and a locking recess. Has been disclosed, and
No. 154221 or Japanese Utility Model Application Laid-Open No. 62-113027 discloses a method for joining side plates vertically divided at a corner portion.
The edge of the side plate is folded outward to form folded pieces of a predetermined width, and the folded pieces adjacent at the corners are embraced and tightened by a reinforcing plate having an L-shaped cross section provided with the folded pieces inward. In the example of adopting the structure of attaching, the outer engagement piece provided on the side plate is inserted into the inward engagement piece provided on the bottom plate, and the inserted state is set by setting the inner bottom plate on the bottom plate. An example in which a fixing structure is adopted is described.

[0003]

In the above assembly box, since the side plates are vertically divided at the corners, the strength of the joints (corners) is weakened, and the reinforcing plate or the like is damaged or deformed by an external force. Or there is a risk of In addition, in the joining of the side plate and the rising wall of the bottom plate, the structure of the side plate and the bottom plate is complicated in the hinge structure described above, leading to an increase in manufacturing cost. Since the pieces protrude from the box and hinder handling, there is a risk of breakage or deformation, and high strength cannot be expected because the joining is also at the corner of the peripheral edge of the bottom plate. Further, in any of the above, the joining structure between the side plates and the joining structure between the side plate and the bottom plate are different from each other, so that the manufacturing cost of the components relating to each structure becomes higher, and the assembly and disassembly of the box itself are further increased. It also takes time and effort.

[0004]

SUMMARY OF THE INVENTION The present invention provides an assembling box which can be easily disassembled and assembled with a simple structure and work, and which can secure the strength at the time of assembling and does not cost much. The configuration is composed of a tray-shaped bottom plate integrally having a rising wall on the four peripheral edges, and a side plate which is joined to the rising wall of the bottom plate and vertically divided except at a corner portion. Folded pieces having a predetermined width are provided on the both side edges and lower edge of the side plate and the upper edge of the rising wall of the bottom plate, respectively, and butt each other, and the butted fold pieces are folded inward on both sides. Characterized by being embraced and fastened by a connector having

[0005]

[Function] When the folded pieces provided on the respective side plates divided at portions other than the corner portion and the rising wall of the bottom plate are respectively butted, and a connecting body is attached to the abutting position,
The folded pieces of the connecting body hold and fix the folded pieces on the box side from both sides, respectively, and the side plates and the bottom plate are integrally joined, so that the box is assembled firmly. Conversely, when disassembling, each side plate and bottom plate can be easily separated simply by removing the connecting body. Because these can be done in a single operation,
Good workability is obtained.
