Description

  The present invention relates to an assembly structure of an article storage such as a stocker stored in a lower space of a commodity display fixture such as a commodity display shelf so as to be drawable.

  The stocker in the conventional merchandise display shelf is a drawer type (see, for example, Patent Document 1) or a caster provided on the bottom surface of the bottom plate so that it can freely move on the floor surface (for example, Patent Document) 2).

  Such a stocker has a box-like assembly structure in which an upper surface is opened by respective constituent members of a front plate, a pair of left and right side plates, a rear plate, and a bottom plate.

However, in the stocker described in Patent Documents 1 and 2, since each component is assembled and integrated by welding to each other in the factory, the manufacturing process becomes complicated, and it is assembled in a box shape. Since the integrated product is subjected to a coating process, the painting operation is difficult and coating spots are likely to occur.
In addition, since the products assembled at the factory are packed as they are and then transported to the site, they cannot be transported in large quantities at a time, resulting in an increase in transportation costs.
JP 2007-130362 A JP 2000-201782 A

  In view of the above situation, the present invention can simplify the manufacturing process by omitting the welding work, facilitate the assembly work, and facilitate the painting work, and also cause coating spots. It is an object of the present invention to provide an assembly structure of an article storage box that can improve the finish of painting and can reduce the transportation cost.

  As described in the respective claims in the column “Claims”, the above-mentioned problems are solved by the invention having the following configuration.

(1) An assembly structure of an article storage room including a front plate, a pair of left and right side plates, a rear plate, and a bottom plate, and the boundary positions of the left and right side plates and the rear plate A single steel plate in which a plurality of slit-shaped holes are arranged along the plurality of holes is bent along the plurality of holes in a U-shape facing forward in plan view.

(2) In the above item (1), insertion grooves that open outward in the horizontal direction are formed on the left and right side edges and the rear edge of the bottom plate, respectively, and are bent into a U-shape in a plan view and connected to each other. The left and right side plates are respectively formed in the lower ends of the left and right side plates and the rear plate with insertion pieces extending in the inward horizontal direction to be inserted into the insertion grooves and inserted into the insertion grooves. In addition, each front end of the bottom plate is abutted against and abutted against the rear surface of the front plate, and is fixed and assembled to each other by a fixing means.

(3) In the above item (1) or (2), the corners of the left and right side plates and the rear plate are concealed from the inside by a corner member, and the corner member is Engage with the hole.

(4) In any one of the above items (1) to (3), the article storage case includes a front plate having a handle on the upper portion, a pair of left and right side plates, a rear plate, a bottom plate, and a bottom plate.
