Description

  The present invention relates to furniture provided with a top board, and more particularly to furniture provided with a top board such as a table or a desk.

  Conventionally, various types of furniture such as tables, desks, tabletops, etc., in which a top plate is supported by legs, have been provided. For example, in Patent Document 1, columnar reinforcing frame members provided with screw holes on both end surfaces are fixed to both ends of the lower surface on the long side of a flat rectangular top plate, and the reinforcing frame material is exposed from the upper surface of the top plate. A melamine resin decorative board is attached over the surface, and a pair of gate-shaped legs with a beam member connected to the upper ends of a pair of legs are closely attached to both end faces on the short side of the top board. A table in which a bolt is screwed into a screw hole of the reinforcing frame member through a through hole penetrating the upper end portion of the leg is disclosed.

  The top plate of the table described in Patent Document 1 has a reinforcing frame member fixed along the lower side of the long side of the top plate, and the reinforcing frame member is wound from the top surface of the top plate and a melamine resin decorative plate is attached. Because of the structure, the front and rear edges of the top plate are processed, but the ends of the top plate, the reinforcing frame material, and the decorative plate are exposed at both ends on the short side. It was covered with. As a result, the four-side end surfaces of the decorative melamine resin plate are not exposed to the outside, and peeling from the end surfaces is prevented. In addition, when connecting between the upper ends of the front and rear legs with a beam member, the leg body adopts a structure in which comb-like engagement teeth formed on each other's connecting part are engaged with each other. The meshing structure of the part is exposed.

However, since it is usually used while sitting on the long side of the top plate, the edge of the top and bottom is very thick due to the reinforcing frame material on this seating side, which becomes an obstacle during use. Or it becomes too heavy in appearance. Further, if seated on the gate-shaped leg body side, the curtain plate provided on the lower surface of the beam member also gets in the way, which makes it difficult to use.
