Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to loads (articles) assembled with supports, shelves, etc.
The present invention relates to the structure of a connecting part of a shelf for storing.

2. Prior Art Conventional shelf connections are made using, for example, Utility Model Application Publication No. 63-36327.
As disclosed in the above publication, hooking holes are formed on both sides of the angled support, and hooking holes that can be locked in the hooking holes are formed in the connectors fixed to the four corners of the shelf board. ing.

Problems to be Solved by the Invention to L It was in a horizontal section for aesthetic reasons. Moreover, since the veneer is bent into an angular shape and a hook hole is formed in the box support, there is a drawback that the strength of the support is significantly reduced.The present invention solves the above-mentioned problems and can completely improve the aesthetic appearance of the shelf. In addition, the overall purpose is to provide a shelf connecting structure that can significantly improve mechanical strength.

Means for Solving the Problems In order to solve the above-mentioned problems, the first means of the present invention is to make both side plates of the angled support installed at the four corners a double structure consisting of an outer plate and an inner plate. An engaging protrusion is provided on one side of the inner side plate of the support column and the angle-shaped coupling members on the four corners of the shelf, and a connecting hole into which the engaging protrusion can be engaged is provided on the other side.

Furthermore, the second means includes forming the support with an angled side plate, an outer end edge of the side plate folded back along the length direction, and a t-side inner plate spaced apart from the outer plate at a predetermined distance. The inner edge of the inner plate is bent toward the outer plate to form a reinforcing edge whose tip is close to the inner surface of the outer plate, and the inner plate is provided with a connecting ring, which engages with the coupling member. Provide a protrusion
It is something.

Effect: By using the first method described above, the angle-shaped support has a double structure, so high strength is obtained, and since the connecting member on the shelf side and the inner plate of the support are connected, there are no irregularities or holes on the outside surface of the support. There is no need to form a top, and the aesthetic appearance can be improved.

By the second method, it is possible to fold the two plates to form a double structure, which is economical, and by folding the inner edge of the inner plate, the inner edge of the inner plate is bent and the reinforcing edge is used to form the connecting hole. The strength of the board can be improved.
