Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a top plate suitably used for office desks and the like.

[Prior Art] In an office desk or the like, a through hole is sometimes provided in the corner of the top plate for inserting a pole for attaching an optional fitting such as a telephone stand or a blindfold panel. Recently, a system has been developed in which the corners of the top plate are supported by leg supports, and wiring raised from the floor can be guided upward through grooves provided on the outer edges of the leg supports. In such a device, it is necessary to provide a wiring insertion hole in a corner of the top plate to lead the wiring onto the top plate.

Therefore, it is common sense to form such a through hole for inserting a pole or a wire insertion hole by drilling a hole from the top surface to the bottom surface of the top plate using a drilling tool such as a drill.

[Problems to be Solved by the Invention] However, when such a hole is formed in the corner portion of the top plate, the wall thickness of the corner tip portion becomes small, and the thin wall portion becomes easily damaged. Further, such a through hole requires drilling each top plate individually, and it is not possible to process a large number of top plates at the same time, so there is a problem that it is difficult to manufacture efficiently.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to solve the above problems, the present invention takes the following measures.

That is, the top plate according to the present invention includes a top plate main body and an edge member. The top plate main body has an edge attachment groove on the outer edge and a notch opening at the corner portion. The edge member includes an exterior part made of soft synthetic resin, a back plate part made of hard synthetic resin integrally formed on the inner surface of the exterior part, and a back plate part that protrudes inward from the back plate part and is attached to the top plate. The mounting leg is press-fitted into the edge mounting groove of the main body. Then, only a portion of the mounting leg portion is cut out to bend the edge member, and the bent portion of the edge member closes the outside of the notch provided in the corner portion of the top plate main body.

If you want to particularly improve the shape retention of the edge member at the corner, it is recommended to make the cutting width of the mounting leg smaller than the opening width of the notch so that the mounting leg exists within the notch. good.

The notch is designed to allow wiring to be passed through it or a pole for attaching optional equipment to be inserted therein.

[Function] With such a structure, a notch can be formed in each top plate body by stacking a large number of top plate bodies and cutting the corners with a rotating cutting blade or the like. can do. After that, by attaching an edge member to the outer edge of each top plate main body, the outside of the notch is closed by the edge member, and an opening form similar to that obtained when a through hole is formed can be obtained.

Moreover, the edge member is provided with a back plate portion made of hard synthetic resin on the inner surface side of the exterior portion made of soft synthetic resin,
This back plate portion also exists continuously at the bent corner portion. Therefore, even if the corners of the top plate are formed only by the knob members, there is no fear that the corner portions will be easily deformed or damaged by external forces.

In addition, the mounting legs made of hard synthetic resin also function as ribs to prevent bending and deformation of the mechanical and mechanical parts.
Make the cutting width of the mounting leg smaller than the opening width of the notch,
If you make the mounting legs extend into the notch from both sides, the part where the mounting legs are located will be the part of the top plate that is not buffered or knobbed (the part facing the notch). Linearity will be maintained even in Therefore, regardless of the shape of the notch opening, it is possible to bend the edge member relatively sharply only in the portion where the mounting leg portion is removed, and the bent shape can be maintained for a long period of time. become.
