Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION The present invention relates to an assembling storage box equipped with a swing door, a sliding door and the like, and is an improvement of the structure of a door frame.

[0002]

2. Description of the Related Art Most of small constructions such as storages are divided into element parts such as panels, columns and beams, which are integrated and supplied in a single packing case. Since the volume of the packaging kit of such an assembling storage is significantly smaller than the volume of the assembled storage, it is suitable for reducing the transportation cost and the storage cost at the time of inventory. On the other hand, since the number of fastening points and fitting engagement points increases, it is difficult to obtain sufficient assembly accuracy. In particular, when forming each element part using a thin steel plate as a material, each part is easily bent and deformed, and the allowable error dimension is set to a large value, so that, for example, the paired panel or column is distorted into a parallelogram shape. It is difficult to obtain sufficient assembly accuracy.

In the case of an assembling storage box having a door on the front side, the above-mentioned distortion of the shape becomes a problem. When the door frame is distorted, a part of the peripheral edge of the door abuts on the door frame, resulting in a malfunction such as scratches or abnormal noise of the coating film. In the case of a sliding door, the door may be caught and the opening / closing operation may not be performed smoothly. In order to avoid such a malfunction, there is an assembling storage box that supplies the door frame in a semi-finished state (Japanese Utility Model Publication No. 57-19013). There, the door frame is composed of an inverted gate-shaped main frame and an upper frame, which are separately screwed to the side plates. The main frame has a pair of side frames integrally fixed to the left and right ends of the lower frame.

[0004]

According to the main frame body previously formed in the inverted gate shape as described above, the pair of side frames and the lower frame can be correctly orthogonalized, but the upper frame is directly connected to this. Since it was not done, it was easy to get out of order when the door frame was assembled. Furthermore, it is necessary to prepare a packing case that can accommodate the gate-shaped main frame for distribution, but even if only the door and the door frame are packed separately from other element parts,
It is inevitable that the packaging of the entire packaging kit will become large.
Therefore, it is not possible to sufficiently reduce the cost required for transportation and storage, but it is inevitable that the main frame is bulky during manufacturing, and it is often used for processing such as welding, cleaning, painting, and handling during packaging. Invites predictions that require time and space.

The object of the present invention is to divide the door frame into four component parts, thereby sufficiently reducing the volume of the packing kit and reducing the cost required for transportation and storage.
Moreover, it is an object of the present invention to provide an assembling storage box in which each of the component parts can be properly assembled without distortion during assembly. An object of the present invention is to provide a storage cabinet which can easily and accurately assemble a door frame and can always open and close the door. An object of the present invention is to provide a storage cabinet equipped with a door frame that can exhibit the same degree of rigidity as a door frame having a welded structure and that is difficult to rattle in an assembled state.
