Description

DETAILED DESCRIPTION OF THE INVENTION This invention involves laminating a decorative board on the upper surface of a furniture for a living room, especially a wooden board, forming an opening in the center for installing a sink, and making the wood around the opening water-resistant. The present invention relates to a method for manufacturing an upper plate coated with a resin.

In recent years, the upper panels of kitchen furniture such as sinks have been made of a wooden board laminated with decorative boards, with an opening formed in the center and a metal sink attached to the opening to connect the two. Things have been proposed and put into practical use. When joining such a wooden top board and a metal sink, it is necessary to make the top surfaces of the two flush with each other from the viewpoint of commercial value. recessed,
A method is adopted in which the upper flange of the sink is overlapped and joined to this recessed portion. However, as a result of removing the decorative board around the opening, the wood is exposed and there is a risk that water may seep in and rot the wood. Therefore, the edges of the opening are usually recessed deeply to ensure water resistance. A method of filling with resin is used.

The present invention aims to provide a method suitable for manufacturing such an upper plate, and will be described in detail below with reference to the drawings.

First, as shown in FIGS. 1 and 2, grooves 2 are formed in the upper surface of a substrate 1, which will be the upper wooden substrate. The groove 2 is formed in an annular shape corresponding to the outer periphery of an opening for installing a sink formed in the upper plate. Two holes 3 are formed at approximately symmetrical positions, the upper end communicating with the groove 2 and the lower end communicating with the lower surface of the substrate 1.

Next, as shown in FIG. 3, a water-resistant synthetic resin board 4 serving as a decorative board is fixed and laminated on the entire upper surface of the substrate 1. The upper surface of the groove 2 is completely closed by the lamination of the synthetic resin plates 4, so that the groove 2 only communicates with the lower surface of the substrate 1 through the hole 3.

Next, as shown in FIG. 4, a water-resistant synthetic resin, preferably an epoxy resin, or a urethane resin 5 is injected into the groove 3 from one side of the hole 3 to fill it. If resin is seen flowing out from the other hole 3, filling of the groove 3 is completed, and the injection is stopped.

After the injected resin has hardened, the substrate 1 and the decorative resin plate 4 are cut out along approximately the center line 6 of the groove 2 in order to form an opening for mounting the sink as shown in FIG. At this time, the decorative resin plate 4 at the opening periphery
is cut out within the upper surface of the injected resin 5.

As a result, it is possible to obtain an upper board consisting of a wooden board and a water-resistant decorative board, which has an opening in the center for attaching the sink, and the wooden part around the opening is coated with water-resistant synthetic resin, as shown in Fig. 6. As shown in FIG.
The sink 7 and the upper plate can be joined together while the sink 7 is placed thereon.

As explained above, according to the present invention, it is possible to extremely easily and mass-produce a top plate in which a water-resistant decorative board is laminated on a wooden board and the wooden part around the sink mounting opening is coated with a water-resistant resin. It can be done.

Claims (1)

[Claims] 1. An annular groove 2 is recessed in the upper surface of the wooden board 1 along the opening for installing the sink, and a hole 3 with the upper end communicating with the groove 2 and the lower end communicating with the lower surface of the board 1 is provided at approximately symmetrical positions. After forming the individual parts, a water-resistant decorative board 4 is superimposed on the upper surface of the substrate 1 to seal the upper surface of the groove 2, and then water-resistant resin is filled into the groove 2 from one of the holes 3 and hardened. A method for manufacturing a top plate of furniture for a living room, characterized in that a substrate 1 and a decorative board 4 are cut out along the lines to form an opening for installing a sink.
