Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of manufacturing a vanity or kitchen counter.

[Background Art] Wooden counters have been known in which a soft resin layer such as soft urethane is formed over the entire length of the front end surface, but the soft resin layer has poor abrasion resistance, so It was not suitable for places where water is used, such as a vanity table. Furthermore, since a decorative board made of hard resin is usually attached to the counter surface, it is not possible to obtain the same texture as the counter surface with the soft resin layer. For this reason, counters with a hard resin layer such as hard urethane that has excellent wear resistance have been proposed instead of a soft resin layer, but the adhesive peels off due to shrinkage of the hard resin layer and is not practical. It was lacking in sex.

[Object of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to form a hard resin layer on the front end of the counter so that it can be used in areas where water is used, such as washstands and kitchens. The object of the present invention is to provide a practical counter by increasing the adhesive strength between the hard resin layer and the front end surface of the counter.

[Disclosure of the Invention] The counter manufacturing method of the present invention involves forming cutting grooves 5 extending from one side to the other on the surface of a wooden substrate 1, and then applying a decorative hard resin plate to the entire surface of the substrate 1. After that, the decorative hard resin board 2 is cut along the approximate center of the cutting groove 5, and then the substrate 1 is cut on the front end side of the cutting groove 5. Board 1 is placed approximately in the center of the front end surface.
A protrusion 3 having a thickness smaller than the thickness of the board 1 is formed over the entire length, and then a hard resin is formed from the back side of the front end of the decorative hard resin board 2 to the protrusion 3 on the front end surface of the substrate 1 by resin molding. The resin layer 4 is characterized in that it has a U-shaped cross section, and with this configuration, the above object can be achieved. That is, cutting grooves 5 are formed on the surface of the wooden substrate 1 from one side to the other.
is formed, and then a decorative hard resin board 2 is pasted on the entire surface of the substrate 1, and then a decorative hard resin board 2 is pasted on the entire surface of the substrate 1.
Since the cutting process is carried out along approximately the center of the cutting groove 5, the dimensional accuracy of the decorative hard resin board 2 can be improved compared to the case where the decorative hard resin board 2 is cut into the final shape in advance. Therefore, when the hard resin layer 4 is formed into a U-shaped cross section from the back side of the front end of the decorative hard resin board 2 to the protrusion 3 on the front end surface of the substrate 1 by resin molding. In this case, reliable adhesion between the decorative hard resin board 2 and the hard resin layer 4 can be ensured.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The board 1 is made of a wooden material such as plywood or wood, and an opening 6 for attaching a washing bowl is formed in the center of the board 1 using a numerically controlled router machine or the like, and the opening 6 is formed from one side to the other.
A cutting groove 5 is formed which is curved along the front end, and alignment through holes 7 are bored on both sides of the front end (FIGS. 1a and 1b). The depth of the cutting groove 5 is, for example, about 7 mm when the thickness of the substrate 1 is 18 mm. Next, a decorative hard resin board 2 made of a hard resin such as a melamine decorative board is attached to the entire surface of the routered board 1 using a rubber-based or vinyl acetate-based adhesive (Figure 2). . After this, the substrate 1 is fixed to a base etc. using the alignment through-hole 7, and the fourth
As shown in the figure, the decorative hard resin plate 2 is cut along approximately the center of the cutting groove 5 by the awl 8 through numerically controlled machining (cutting line C). The cut end of the decorative hard resin board 2 protrudes to approximately the center of the cutting groove 5. Cutting is done by numerical control, so
This protrusion length is constant over the entire length, and can be changed arbitrarily. In this case, the decorative hard resin board 2 is cut along the edge of the opening 6 for attaching the washing bowl. After that, as shown in FIG. 4, by cutting the substrate 1 at the front end side of the cutting groove 5 with an inverted T-shaped cone 9, the thickness of the substrate 1 is cut approximately at the center of the front end surface of the substrate 1. A protrusion 3 having a small thickness is formed over the entire length. Next, the hard resin layer 4 is formed into a U-shaped cross section from the back side of the front end of the decorative hard resin board 2 to the protrusion 3 on the front end surface of the substrate 1 by resin molding. In this way, a counter A as shown in FIG. 5 is manufactured. This counter A can be suitably used as a bathroom vanity or a kitchen top.

[Effects of the Invention] In the present invention, cutting grooves extending from one side to the other side are formed on the surface of a wooden substrate, and then a decorative hard resin plate is attached to the entire surface of the substrate, After this, the decorative hard resin board is cut along the approximate center of the cutting groove, so compared to the case where the decorative hard resin board is cut into the final shape in advance, the decorative hard resin board is cut into the final shape. Therefore, when the hard resin layer is formed into a U-shaped cross section from the back side of the front end of the decorative hard resin board to the protrusion on the front end of the board by resin molding, To,
It is possible to ensure reliable adhesion between the decorative hard resin board and the hard resin layer. As described above, since the counter manufactured by the present invention has a hard resin layer formed on the front end, it can be suitably used in places where water is used, such as washstands and kitchens. is formed in a U-shaped cross section from the back side of the front end of the decorative hard resin board to the protrusion on the front end surface of the board, so that the hard resin layer is formed between the decorative hard resin board and the protrusion of the board. The adhesive strength is increased by adhesion, and since the decorative hard resin board and the hard resin layer are both hard, it is possible to obtain the same texture.
