Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembled shelf in which a shelf board and a side board of a unit shelf or the like are firmly fixed by a shelf holder, and the shelf board can be added or removed without moving.

Conventionally, assembled shelves have been made of wood-based materials or metal, but those made of wood-based materials are those made of natural wood planks or synthetic resin on the outer surface of particle board, fiberboard, etc. There are sheet overlays made of plywood, etc., but they have drawbacks such as warping and wrinkling, and are heavy and inconvenient to handle.Also, metal products are made of metal, even though they are sturdy due to the material. It has the disadvantage that it is not suitable for wooden houses due to its weight and the texture of the material.

The present invention was made in view of the above circumstances, and the side plates and shelf plates have high compressive strength, especially strength against bending and torsion, and are durable.The thickness of the shelf plates and side plates can be freely changed and heavy objects can be placed on them. Despite the fact that the side panels and shelf boards themselves are lightweight and strong, they do not warp or twist, and the exterior is covered with a decorative sheet, making it possible to produce assembled shelves in large quantities at low cost with an extremely beautiful and excellent design. This is what we intend to provide.

Hereinafter, the present invention will be explained in detail according to embodiments shown in the drawings.

The shelf board 1 and the side board 2 have substantially the same configuration.

That is, as shown in FIG.
Printed paper, cloth, vinyl chloride resin sheet or film (
It is simply called a ``decorative sheet.''

) 5 and at intervals corresponding to the thickness t and width L of the intended shelf board 1 or side board 2 as shown in FIG.
A surface plate 7 is prepared in which a plurality of V-shaped bending grooves 6 are opened in parallel in the longitudinal direction to reach the decorative sheet 5 but not damage it. On the surface of the substrate 4 on which the decorative sheet 5 is not attached, approximately circular core materials 8 are arranged at appropriate intervals, and columnar core materials 9 are also attached to the surface of the substrate 4 of the surface plate 7. The decorative sheet 5 is placed on the non-adhered surface, and as shown in FIG.
