DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf used in an office or the like.

[0002]

2. Description of the Related Art As one of shelves used in offices and the like, a pair of left and right side walls is mounted on hook holes provided in columns or the like of a partition panel, and a shelf plate is held between these side walls. Things are known. The side wall body of this shelf is a hollow body in which a sheet metal outer plate and an inner plate are attached to each other, and they are joined at their peripheral edges by welding or the like, and claws and shelf receiving portions are attached to the outer plate and the inner plate. Usually, they are provided integrally by sheet metal processing.

[0003]

However, in order to manufacture such a side wall body, at least one of the face plates is provided.
Processing corresponding to a relatively complicated shape such as a peripheral portion or a corner portion must be performed. For this reason, it becomes impossible to use a thick sheet metal material, and there arises a problem that it is difficult to provide a nail or a shelf receiving portion formed by sheet metal processing with sufficient strength. In particular, since the claws are often provided offset on the same surface as the outer surface plate of the side wall body in order to prevent the entire shelf from protruding laterally from the left and right hook holes, the load easily acts as bending stress, The problem of easy deformation due to insufficient strength occurs. On the other hand, resin parts and the like are often used for the treatment of corner portions, etc., which are difficult to cope with simply by reducing the thickness of the face plate, and reinforcement between the face plates to compensate for insufficient strength. It is customary to hold a crosspiece or a urethane foam for preventing depression. For this reason, there is a problem that the total number of parts increases, which leads to an increase in the number of manufacturing steps, weight, cost and the like. Furthermore, the conventional one has a problem that the paint is easily peeled off or damaged due to the metal contact between the shelf plate and the side wall body by repeatedly attaching and detaching the shelf plate, and furthermore, a predetermined accuracy cannot be obtained by sheet metal processing. In many cases, there is a problem that rattling easily occurs between the shelf and the side wall.

An object of the present invention is to solve such a problem at once.

[0005]

In order to achieve the above object, the present invention employs the following configuration.

That is, in the shelf according to the present invention, a shelf plate is held between a pair of left and right side wall members, and the side wall members are attached to hook holes. A metal core material having a claw portion that engages with the hook hole at an edge thereof and a shelf receiving portion that supports a shelf plate formed at a horizontal lower edge of the face plate portion, and covers the face plate portion of the core material. The outer cover and the inner cover made of synthetic resin.
It is assumed .

As a specific mode of mounting the cover, the lower edge and the rear edge of both covers are brought into contact with the face plate portion of the core material, and the engaging portions provided at the front edge and the upper edge, respectively. Are engaged with each other at positions avoiding the face plate portion of the core material.

In order to prevent displacement of the covers, annular protrusions are provided on the opposing surfaces of both covers, respectively, and the engaging portions provided on the protrusions are provided with a face plate of a core material. It is effective to engage the concave and convex with each other at the avoided position.

In order to enhance the utility value of the raised portion, it is preferable to form a through window inside the raised portion.

In order to allow the two covers to be easily positioned with respect to the core material, the raised portions are fitted through holes provided in the face plate portion of the core material. It is desirable that the raised portion be provided with a locking piece that engages with the periphery of the hole at the penetrating position.

As a specific embodiment of the shelf receiving portion,
The shelf receiving portion is a bent piece provided integrally with the core material, and a side frame portion of a shelf plate is fitted between the bent piece and the inner surface cover from above.

In order to dispose the entire shelf without protruding laterally from the left and right hook holes, the claw portion of the core material is bent with respect to the face plate portion, and the claw engaging with the hook hole is formed on the outer surface. It is preferable to dispose them on substantially the same plane as the cover.

[0013]

With such a structure, the core material is covered.
Since it is separate from the shelf, the core material alone can be made thick without affecting the appearance of the shelf, and the nails and the like can have strength. On the other hand, since the cover is made of a synthetic resin and can be molded freely, it is possible to cope with complicated molding such as a corner without using auxiliary parts. Furthermore, since synthetic resin is lighter in weight than sheet metal, it is easy to secure the thickness necessary to prevent sticking. for that reason,
It is not always necessary to have a reinforcing bar, urethane foam, etc., which increase the number of parts, the number of manufacturing steps, the weight, etc. inside. In addition, since both sides of the shelf are pressed against the inner cover made of synthetic resin, even if the shelf is repeatedly attached and detached, the paint on each part will come off or be damaged due to the contact between metals. Is reduced, and
If the mounting state of the shelf is improved by utilizing the elasticity of the inner cover, it is possible to reduce the play between the shelf and the side wall.
