Then, a synthetic resin material 11 with a sealing property is applied along the upper end of the sink 3 and the inner peripheral edge of the opening 9, and a synthetic resin material 11 with a sealing property is applied to the recess formed by the mounting opening 8 and the flange 3a. Filling with resin material 11,
become stuck to each other. This prevents moisture from penetrating between the decorative board 7 and the sink 3, and even if it does, it will not drip onto the main body 1.

However, even with this configuration, in order to use the synthetic resin material 11 as shown in the figure, a mold is required to improve the appearance, and the fixing process takes a long time, so high costs are unavoidable.

The present invention was developed in light of the above circumstances, and its purpose is to provide a sink installation that reliably prevents moisture from penetrating and improves durability, while having a relatively simple structure. The aim is to provide equipment.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a mounting plate having an opening in the decorative board, communicating with the opening, and having a mounting opening having a diameter larger than the opening. is fixed to the lower surface of the decorative board, and a gasket with a substantially L-shaped cross section is adhered around the mounting opening on the bottom surface of this mounting board and around the opening on the bottom surface of the decorative board, and the flange of the sink is attached to the bottom surface of this gasket. abutting the parts to close the mounting opening of the mounting plate, and providing a fixing member on the lower surface of the mounting plate to press and fix the flange of the sink toward the packing, and attach the packing via the flange. The sink mounting device is characterized in that it presses the area around the installation opening of the board and the area around the opening of the decorative board.

(Function) With such a configuration, the packing closely contacts the area around the opening on the lower surface of the decorative board, the area around the mounting opening on the lower surface of the mounting plate, and the flange of the sink to prevent moisture from penetrating. Further, the entire circumferential surface of the mounting opening of the mounting plate is covered by the gasket.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Reference numeral 20 in FIGS. 2 and 3 denotes a top plate, which is made up of a decorative board 21 and a mounting plate 22 stacked one above the other and fixed to each other, and is provided in a vanity washbasin. The decorative board 21 is made of, for example, a synthetic resin material, and is slightly recessed approximately at the center thereof, and is provided with an opening 23 . The mounting plate 22 is made of wood, for example, and is adhered to the lower surface of the decorative board 21. The upper surface of this substantially central portion is recessed along the recessed portion, communicates with the opening 23, and has an attachment opening 24 having a larger diameter than the opening 23. In addition, the installation port 24
To explain this, this is a hole with a stepped cross section, with the diameter on the lower side being larger than on the upper side, which is the side to be bonded to the decorative board 21. Reference numeral 25 denotes a packing made of a rubber material, and is formed into a substantially L-shaped cross section. The top surface with the step is the mounting opening 2 on the bottom surface of the mounting plate 22.
4 and around the opening 23 on the lower surface of the decorative board 21. Patsukin 2 installed
The inner diameter of the opening 23 is the same as the diameter of the opening 23. Further, this lower surface is provided with a sealing surface 25a consisting of a large number of fine protrusions. A sink 26 is made of, for example, stainless steel. A flange 26a formed along the outer peripheral edge of the sink 26 is fixed by pressing against a sealing surface 25a of the gasket 25 by a fixing member 27, which will be described later. In other words, the collar portion 26a and the gasket 25 are press-fixed between the fixing member 27, the decorative board 21, and the mounting plate 22. The fixing member 27 includes a fixing piece 29 that is screwed onto the lower surface of the mounting plate 22 with machine screws 28, 28 such that one end protrudes into the mounting port 24, and this fixing piece 29.
A fixing bolt 30 is screwed into the protruding end of the mounting opening 24 of 9. A presser piece 31 is integrally provided at the tip of the fixing bolt 30, and is in contact with the flange 26a over a wide area.

Since the sink 26 is installed and fixed in this way, even if hot water is used, the decorative board 21 and the mounting board 2
2, between the decorative board 21 and the mounting plate 22, and the flange 26a of the sink 26, and between the flange 26a and the packing 25. That is, since the packing 25 is in contact with the periphery of the opening 23 on the lower surface of the decorative board 21 and is adhered along the periphery of the mounting opening 24 on the lower surface of the mounting plate 22, moisture penetration from between the decorative board 21 and the mounting plate 22 is prevented. completely prevent. Since the fixing member 27 presses and holds the flange 26a between the decorative board 21 and the mounting plate 22, the decorative board 2
1. Mounting plate 22, packing 25 and collar 26
This means that it is possible to completely prevent moisture from penetrating between a and a.

In particular, since the sealing surface 25a of the packing 25 is formed from a large number of fine protrusions, the unevenness and elasticity can ensure sealing performance against the flange 26a.

Note that before installing the sink 26, processing as shown in FIG. 4 is required. That is, as shown in FIG. A, the mounting plate 22 is first provided with a mounting opening 24 having a stepped cross section. This attachment port 24 has a larger diameter on the upper side and a smaller diameter on the lower side in the figure. However, the peripheral edge of the lower surface of the mounting plate 22 of the mounting port 24 needs to be recessed. As shown in Figure B, a packing 25 having a substantially L-shaped cross section is adhered along the circumferential surface of the mounting port 24 of the mounting plate 22.

The sealing surface 25a is on the upper side in the figure. Next, as shown in Figure C, the mounting plate 22 and the gasket 25 are turned upside down, and then the decorative board 21 with the opening 23 is placed on the upper surface of the mounting plate 22 and bonded. At this time, the decorative board 21 may be bonded to the packing 25 while being bent into a concave shape around the opening 23. Then, as shown in FIG. 2 above, the flange 26a of the sink 26 may be fixed with the fixing member 27. The entire circumferential surface of the mounting port 24 of the mounting plate 22 is covered with a packing.

In the above embodiments, a sink used in a vanity washstand has been described, but the present invention is not limited thereto, and can of course be applied to a sink provided in kitchen furniture such as a sink.

[Effect of idea]

As explained above, according to the present invention, the cross section approximately L
It has a relatively simple structure in which the letter-shaped seal seals the decorative board and the mounting plate at the same time, and the fixing member presses and fixes the seal through the flange of the sink, completely preventing moisture from penetrating. It is possible to improve the durability of the sink and its attached parts.

The entire periphery of the mounting opening on the mounting plate is covered with packing to improve the appearance.

Furthermore, since the seal is provided with a sealing surface consisting of a large number of small protrusions and brought into close contact with the flange, the sealing performance can be ensured.
