Abstract

PURPOSE:To obtain the top plate of a desk and a table effectively at low cost by following method in which a four peripheral frame is spot-welded to the inner peripheral edge of a back plate, and a front plate is arranged on said frame, and further after the peripheral edge-member consisting of a elastic body is fitted to the four peripheral frame, it is carried into a shape-keeping stand, and then the foaming resin which has been poured is caused to foam. CONSTITUTION:The four peripheral frame 4 consisting of a front plate 4a, a back plate 4b and a pair of side plate 4c is spot-welded to the peripheral internal side of a back plate 3. Next, a front plate 1 is stuck onto the four peripheral frame 4 by way of the tape with adhesive on both surfaces, and then a front edge 2a, a rear edge and a side edge 2c and a corner edge 2d are fitted thereon. The top plate thus obtained is carried into a shape-keeping stand, and at the condition in which the shape of a top plate is kept without deform, foaming resin 8 is charged from the pouring port equiped at a part of the back plate and is caused to foam. After the foaming resin is filled in the gap between the front plate 1 and the back plate 3 and further in the inner part of the four peripheral frame 4, it is hardened, thereby providing the objective top plate of a desk and a table.

図したものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a top plate for a desk, table, etc.・ Conventionally, in metal desks, tables, etc., a gap was created between the top plate and the back plate to form the thickness of the top plate.
There are two types: one in which a reinforcing frame is placed in the gap, and the other in which the gap is filled with foamed resin.The present invention belongs to the latter type, and its purpose is to simplify the manufacturing process as much as possible and reduce costs. It is intended to provide a top plate that can be used for measuring purposes as well as having a sufficient level of accuracy.

以下図面に示した実施例に基いて本発明方法を説明する

鋼板１ｂとの貼り合せからなる。1 to 5 show an embodiment of the top plate according to the present invention, and FIG. 1 is a perspective view of the completed top plate, with the top plate 1
and a peripheral edge material 2 made of an elastic body that goes around the top plate 1, and the peripheral edge material 2 includes a front edge 2a and a rear edge 2.
b, a pair of side edges 2C and a corner edge 2d, and the top plate 1 is made of a decorative board 1a' and a steel plate 1b bonded together as shown in the second figure.

c and 4c are spot welded to each other via the mounting plate 5. At this time, after the mounting plate 5 is spot welded to each of the four peripheral frames 4, the mounting plate 5 is spot welded to the back plate 3. . (Or, of course, there is no problem if you do the opposite.) Next, as shown in FIG.
After fitting the rear edge 2b and side edge 2c to the front plate 4a, rear plate 4b, and side plate 4c, respectively, the corner edges 2d are finally fitted to the four corners to form a top plate, which is not shown in the drawing. While the top plate is fitted into the top plate to prevent it from losing its shape, foamed resin 8 is filled and foamed at a desired position, for example, through an injection hole provided in a part of the back plate 3, as shown in the fourth figure. Top plate 1
Not only does it fill the gap between the top plate and the back plate 6, but it also fills the inside of the four-frame frame 4 through a large number of through holes 6, and is bonded to the peripheral material 2, thereby further improving the reinforcement of the peripheral edge of the top plate. be.
