Description

  The present invention relates to a metal cabinet having a side plate and a back plate formed of a metal plate, and belongs to the technical field of kitchen furniture.

  2. Description of the Related Art Conventionally, some cabinets installed in a kitchen are composed of a metal plate such as a stainless steel plate in order to impart durability, luxury, and the like. For example, Patent Document 1 discloses a metal cabinet formed by joining a member formed by bending a metal plate into a panel shape with a fixing member such as a screw.

  Based on the above technique, for example, in the case of a “side plate winning structure” as shown in FIG. 10, a pair of left and right side plates A (only shown on the right side) forming the storage space S and a back plate B connecting the rear end portion of the side plate A. Is formed by bending a relatively thin metal plate, and has large storage space forming surfaces A1 and B1 extending vertically and from both upper and lower end edges of the storage space forming surfaces A1 and B1. The upper flange surfaces A2 and B2 and the lower flange surfaces A3 and B3, which are bent toward the outer side, the fore end surface A4 which is bent toward the outside of the cabinet from the rear edge of the storage space forming surface A1 of the side plate A, and It has a small face B4 (only the right side is shown) bent from the left and right end edges of the storage space forming surface B1 of the back plate B toward the outside of the cabinet. Then, the side plate A and the back plate B are joined with screws C in a state where the small edge surface B4 of the back plate B is abutted against the rear end side of the storage space forming surface A1 of the side plate A.
