Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a member for a top plate attached with a thermosetting resin decorative laminate used for, for example, a bathroom vanity or a sink. To provide a new member for a top plate with a water tank that is easy to manufacture and excellent in economical efficiency.

Conventional top plates with water tanks attached with thermosetting resin decorative boards include those using the so-called over-sintering method, in which the flange of the water tank is joined from the top surface of the opening of the large board, and the one using the so-called over-sintering method, in which the flange of the water tank is joined from the top surface of the opening of the large board. There is a so-called under-sinter method in which seven lung parts of the water tank are joined together.

FIGS. 1 and 2 are longitudinal cross-sectional views of a water tank joint portion of a conventional top plate with a water tank.

First of all, Fig. 1 shows the opening of the top plate (1,0 melamine resin decorative board) which has a base plate opening e→ which is smaller than the outer peripheral edge (b) of the aquarium flange part (a). This figure shows a top plate with a water tank to which the water tank flange portion (A) is joined via a silicone resin filler layer (E) formed on the surface adjacent to C). Although this large plate with a water tank has the advantage of being easy to manufacture, since it is an oversink type, it has the following problems. In other words, in this top plate with an aquarium, the aquarium flange part (on the melamine resin decorative board) is placed on the upper surface of the aquarium via a silicone resin filler layer (e).
A) is mounted and joined from the top of the top plate. As a result, a corner is formed between the decorative board () and the outer peripheral edge (b) of the aquarium flange, so water and dirt tend to accumulate in this corner, resulting in poor cleaning performance. For long-term use, the aquarium flange part (a) and melamine resin decorative board)
There is a drawback that water can enter through gaps in the joint surface and rot the base plate opening (c). Then the second
The figure shows another example of a baseplate, which has three baseplate openings that are larger than the outer periphery (B) of the water tank flange (A), and is attached to this baseplate so that the openings (C) Melamine resin decorative board with a protrusion (T) between 1 and 0 thick)
A urethane resin primary injection hardening layer H) is formed on the back side of the protruding part (G) of the top plate to which is pasted, and the water tank flange part H) is joined to this back side via a silicone resin filler layer (W). This figure shows a top plate with a water tank on which a reinforcing tool is wrapped and a second injection hardening layer of urethane resin is formed on the back side of the flange.

This top plate with a water tank is an undersink type, so the water tank is located below the surface of the top plate, making it easy to sweep up water.

Furthermore, since the water tank flange portion (a) is surrounded by primary and secondary urethane resin injected hardening layers, it has a structure that is excellent for water drainage. However, this large board with a water tank requires the formation of a primary injection hardening layer (T) of urethane resin that reinforces the protruding parts (T) of the melamine-resinated decorative board, which makes manufacturing complicated, and is also said to be less economical. There was a big drawback.

The present invention solves the various drawbacks of the conventional art described above.In summary, the present invention solves the problem of the opening of a thermosetting resin decorative board having a thickness of 2.0 mm or more and having an opening smaller than the outer peripheral edge of the aquarium flange. The aquarium flange portion is bonded to the back surface via an adhesive water-resistant resin layer, and a hardened thermosetting resin layer is formed on the back surface of the flange portion and a part of the back surface of the thermosetting resin decorative board adjacent thereto. The present invention provides a member for a top plate with an aquarium.

Embodiments of the present invention will be specifically described below based on the drawings. First, FIG. 3 shows a perspective view of a top plate member with a water tank according to the present invention. This figure shows the appearance of a top plate member with a water tank in which a water tank (3) is brought into contact with the end surface (2) of a decorative board made of thickened melamine resin and laminated resin. Next, FIG. 4 shows a vertical sectional view of the aquarium mounting portion of the A-x longitudinal section of the top plate member with an aquarium shown in FIG. This member for a top plate with an aquarium has a melamine resin decorative board opening (6) smaller than the outer periphery (5) of the aquarium flange (4) on the back side of the opening of the 3,0 melamine resin decorative board (1).
