Abstract

PURPOSE:To easily form a top board without rounding each corner of the top board body, by forming a recess having a shape such that it is cut wall- thicknesswise from the outer surface of in edge member, in the rear edge side of the edge member. CONSTITUTION:A recess 231 having a cut-in shape is formed in the rear edge side outer surface of a side edge member 23 laid along each of the left and right side edges of a top board body 1, being integrally formed with the side edge member 23 during resin molding. When the side edge makes contact with a wall or top boards are make contact with each other through their side edges, the recess 231 defines an opening which is used as a relief for a wiring laid cover a desk or a table, and for clamps with which a stand is installed. Accordingly, it is possible to eliminate the necessity of rounding each of the corners of a top board core 11, an outer surface decorating panel 12 and a rear surface decorating panel 13. Since the top board can be easily formed without increasing the number of process steps, and further since cutting an extrusion molding article to a predetermined length, can be simply made along the recess 231 so as to form the top board, the process can be simplified.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top board which is preferably used for desks, tables and the like arranged in offices.

[0002]

2. Description of the Related Art Recently, with the progress of office automation in offices, wirings of various devices have been often laid in the office. Then, in order to store and arrange the wiring in a nice manner, various devices have been devised. As a part of this, for example, in a desk or table having a shape in which a rear edge portion and a side edge portion are orthogonal to each other, a so-called R processing is applied to a corner portion on the rear edge side of the top plate, thereby R when the side edges are brought into contact with the wall or the side edges of the top plates are butted against each other
It is considered that the processed part forms an opening so that it can be used as a relief when wiring is laid on a desk or table or when clamps of a stand are attached.

[0003]

However, such a structure has a problem that the manufacturing process is complicated. That is, when R-working is applied to the corners, it is customary to perform punching work, but this work requires a separate process from the top plate manufacturing, so the number of processes increases and a dedicated machine tool is used. Will be required. In particular, since the top plate is generally constructed by stacking multiple plates in the thickness direction, the above processing is applied to each plate, and the total number of steps is further increased. become.

The present invention has been made in view of the above problems, and an object thereof is to provide a top plate having an opening on the trailing edge side, which can be easily and appropriately manufactured.

[0005]

The present invention adopts the following constitution in order to achieve the above object.

That is, the top plate of the present invention comprises a top plate body having a rear edge portion and a side edge portion orthogonal to each other, and an edge member attached to the side edge portion of the top plate body. In this top plate, a concave portion having a shape cut into the thickness from the outer side surface is provided on the rear edge side of the edge member.

[0007]

With such a structure, when the side edges of the top plate are brought into contact with the wall or the side edges of the top plates are abutted against each other, the concave portion forms an opening. The corners of the plate body do not need to be rounded, and the recess can be easily formed without increasing the number of steps when the edge member is resin-molded, for example.
Therefore, according to the present invention, the top plate for forming the opening at the rear edge can be manufactured extremely easily and appropriately as compared with the conventional case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

This top plate is used for an office desk and comprises a top plate main body 1 and an edge member 2 as shown in FIG.

As shown in FIG. 2, the top plate main body 1 has a top plate core material 11, a surface decorative plate 12 attached to the surface of the top plate core material 11, and a back surface of the top plate core material 11. Back decorative plate 1 to be worn
3 and 3 are polymerized in the thickness direction. Top plate core material 11
Is a rectangular thick plate and has an appropriate internal structure such as a structure in which steel thin plates are attached to both surfaces of a core material. The surface decorative plate 12 is a rectangular resin thin plate having the same size as the top plate core material 11, and is attached to the upper surface of the top plate body 1. The back surface decorative plate 12 is a rectangular plate having the same size as the top plate core material 11 and a thin plate made of an appropriate material, and is attached to the lower surface of the top plate body 1.

The edge member 2 includes a leading edge member 21 and
It is composed of a trailing edge member 22 and a side edge member 23. Leading edge member 21 and trailing edge member 22
Is made of resin having a wall thickness of, for example, about 5 mm, and is attached to the front edge and the rear edge of the top plate body 1, respectively. The side edge members 23 are made of resin and have a wall thickness of, for example, about 10 mm, and are attached to the left and right edges of the top plate body 1, respectively. On the outer surface of the side edge member 23 on the rear edge side, a recess 231 having a length of about 100 mm and a thickness of about 5 mm is integrally molded at the time of resin molding. That is, the concave portion 231 has a shape in which the front end faces the step portion 231a formed in the edge member 23, and the rear end is directly opened to the rear edge side of the top plate body 1. Then, due to the presence of the recess 231,
When the side edges of the top plate are brought into contact with the wall or the side edges of the top plates are abutted against each other, the recess 231 forms the opening 3 as shown in FIG. 3 and the wiring is performed on the desk or the table. It is used as a relief when pulling a and when attaching the clamps of the stand.

With such a structure, the top plate core member 11, the top decorative plate 12, and the back decorative plate 1 of the top plate main body 1 are formed.
It is not necessary to perform the corner R processing for forming the opening 3 on the sheet 3. Therefore, the number of manufacturing processes is reduced and the types of machine tools required for machining are reduced.
That is, the concave portion 231 of the side edge member 23 can be easily formed by resin molding without increasing the number of steps as described above, and also in the case of extrusion molding, the concave portion 231 is cut after cutting to a required length. Since it can be formed by performing a simple cutting along with, the process becomes extremely simple and appropriate as compared with the conventional method.

The structure of the present invention is not limited to that described above, and for example, the recess 231 may be provided in only one of the side edge members 23. Further, the shape of the concave portion can be modified in various ways other than those described above. Further, the shape of the top plate 1 is not particularly limited as long as at least the rear edge portion and the side edge portion are orthogonal to each other. Furthermore, the material of each member can be variously modified without departing from the spirit of the present invention.

[0014]

As described above in detail, the top plate of the present invention has
Since it is not necessary to perform the corner R processing for forming the opening on the top plate main body, the manufacturing process of the top plate is reduced, and the number of machine tools required for the processing is also reduced. That is, the recess of the edge member in the present invention can be easily formed by, for example, resin molding without increasing the number of steps. Therefore, the production of the top plate for forming the opening is extremely simple and appropriate as compared with the conventional case. Becomes
