Description

[Detailed explanation of the invention] This invention relates to the top plate of a kitchen sink, and more specifically, it provides high water resistance to the top plate, which lacks water resistance, so that a sink made of metal etc. can be integrated into the top plate. The present invention relates to a new structure of the upper plate.

In place of the conventional sink top plate, in which the flat counter surface and sink are integrally formed by pressing metal plates such as stainless steel, in recent years only the sink part has been made of metal,
A top plate including a flat counter surface is made of a material with poor water resistance, such as wood, and the sink portion is attached to an opening in the top plate.

The top plate has great advantages in terms of material costs, equipment costs, etc., and also eliminates the cold feeling of metal, giving a good impression to the user, but there is a drawback in the water resistance of the top plate part. Various proposals have been made to improve this water resistance.

Improving the water resistance of the surface of a wooden tabletop is distantly related by laminating a highly water-resistant board material such as melamine resin there, but in order to join the tabletop and the sink, It was difficult to treat the end portion of the formed sink mounting opening to improve its water resistance.

For this purpose, a member made of a highly water-resistant synthetic resin is integrally connected to the opening of the top plate, and when this synthetic resin member is joined to the top plate, the flange of the sink is simultaneously embedded in the member. A structure has been proposed in which a board and a sink are connected using a water-resistant member.

However, in such a structure, the weight of the sink is supported by a water-resistant member made of synthetic resin, which has drawbacks in terms of strength, and since the water-resistant member is exposed on the surface, The surrounding area could not be finished neatly, and there was a risk that the commercial value of the sink would decrease.

This invention was devised to solve the above-mentioned problems found in the prior art, and will be explained in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a top plate, in which a water-resistant surface plate 1b, which also serves as a decorative board, is laminated and integrated on top of a lower wooden board 1a.

An opening 2 is formed approximately in the center of the top plate 1 to accommodate a sink portion made of metal or other material.

The surface plate 1b is made of, for example, a thin plate made of melamine resin, and is bonded to the wooden substrate 1a, thereby forming the base plate 1a.
The surface of the top plate 1 is protected and the water resistance of the surface of the top plate 1 is improved.

The surface plate 1b extends toward the opening 2 together with a portion of the wooden substrate 1a below it to form an eave-like extension 1c.

As shown in the figure, the upper surface of the eave-like extension 1c is formed into an inclined surface 1d that slightly descends toward the opening, and serves as a mounting surface for a sink, which will be described later.

Reference numeral 3 denotes a water-resistant connecting member bonded to the periphery of the opening of the wooden board 1a, which is continuous with the end face of the extending portion 1c of the top plate and is bonded to the extending portion 1c.

The connecting material 3 is preferably selected from a material having high water resistance and elasticity, such as urethane resin.

As shown in FIG. 2, the connecting member 3 is formed by molding urethane resin into columns and is integrated with the peripheral edge of the extending portion 1c of the wooden board 1a and the flange portion 4a of the sink 4.

However, the extension part 1c is molded separately and attached with adhesive.
It may be joined to.

In the case of injection molding, as shown in the figure, a column space is created between the periphery of the extending portion 1c and the sink 4 using molds 5a and 5b), and urethane resin is placed in the column to form the top plate 1. The sink 4 is strongly joined to the sink 4, and the watertight sealing ability between the two is enhanced.

Furthermore, in the case of joining with adhesive, the connecting material 3 is fixed to the wooden substrate 1a with wood screws to achieve the same effect.

In the fixed state, the upper peripheral flange portion 4a of the sink 4
is placed and supported on the upper inclined surface of the extending portion 1c, and the upper surface of the connecting member 3 is covered with the flange portion 4a of the sink 4,
Exposure of the connecting member 3 is prevented.

Further, by placing the flange portion 4a on the descending slope of the extension portion 1c, the top plate 1 and the upper surface of the sink 4 can be positioned substantially on the same plane.

FIG. 3 shows another embodiment of this invention, in which a horizontal portion 1d extending horizontally at the tip of the extending portion 1c is further extended, and the presence of the horizontal portion 1d forms a surface plate 1b. This is designed to further improve the bondability with the wooden substrate 1a.

Also, c) When the surface plate 1b is made of a metal such as a stainless steel plate due to the presence of the filter horizontal portion 1d, the remaining stress on the surface plate 1b can be eliminated by machining the inclined surface of the extending portion 1c. .

In this way, according to the top plate of the kitchen sink of this invention, the upper part of the periphery of the opening of the top plate 1 extends toward the opening 2 to form the extending portion 1c, and the extending portion 1c Open the top surface 2
Since it is formed with an inclination 1d that descends toward , it is possible to reliably prevent water from entering between the sink 4 and the connecting member 3.

As a result, in cases where the top plate and the sink are constructed as separate bodies and the two are joined together, there is a risk that the top plate may be corroded by water entering through the joint between the two. This eliminates any obstacles to using a wooden top plate.

Further, the peripheral flange portion 4a of the sink 4 is placed and supported on the slope 1d of the extension portion 1c of the top plate 1, so the weight of the sink 4 is borne by the top plate 1, and the connecting member 3 No weight is applied to the sink 4, the mounting condition of the sink 4 is stable, and since the connecting member 1 is covered with the flange part 4a of the sink 4, the appearance is good and the commercial value of the sink can be increased.

Furthermore, since the sink 4 is embedded in the connecting member 3, coupled with the fact that it is supported by the top plate 1, the sink 4
The sink 4 can be fixed to the top plate 1 without requiring any special means for fixing the sink 4 to the top plate 1.
