Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technique for fitting a washbowl to the bottom side of a hole provided in a counter so that the attachment part can be fitted in a good manner from the viewpoint of appearance and waterproofing.

[Background Art] Conventionally, as shown in FIG. 4, a hole 3 for attaching a washbowl with a decorative rim 2 is provided on the inner circumference of a counter 1, and the upper opening is connected to the counter 1.
The outer flange 5 provided on the upper outer periphery of the washbowl 4, which is slightly larger than the hole 3, was simply attached to the outer periphery of the hole 3 on the lower surface of the counter 1 using a fitting 11. The reason why the upper opening of the washbowl 4 is made slightly larger than the hole 3 of the counter 1 is that if the upper end of the inner wall of the washbowl 4 is exposed inside the hole 3 of the counter 1, the appearance will be extremely unsightly. As the product value deteriorates significantly, the upper opening of the washbowl 4 is made slightly larger than the hole 3 of the counter 1, taking into account manufacturing and assembly errors, and the upper end of the inner wall of the washbowl 4 is is located outside the hole 3. However, if the upper opening of the washbowl 4 is made slightly larger than the hole 3 of the counter 1, as shown in FIG. becomes a stepped portion 12, and there is a problem that dirt such as limescale adheres to this stepped portion 12 and it becomes dirty. There was a risk that water would leak through the space between the upper surface of the flange 5 and the upper surface of the flange 5 due to capillary action.
In particular, the corner between the lower surface of the decorative rim 2 and the inner wall of the washbowl 4 has an acute angle as shown in FIG. There was a problem that the water leaked outside through the space between the water and the top surface of the outer flange 5 of the washbasin 4.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to reduce the gap between the upper end of the inner wall of the washbowl and the lower end of the inner periphery of the hole in the counter. To provide a structure of a mounting part of a washbowl to a counter, which hides a stepped part to prevent dirt from adhering to this part and prevents water from leaking from the mounting part of the washbowl.

[Disclosure of the invention] The structure of the part for attaching the washbowl to the counter of the present invention is that the counter 1 is provided with a hole 3 for attaching the washbowl 4, and the upper opening is attached to the counter 1.
An outer flange 5 provided on the upper outer periphery of the washbowl 4, which is slightly larger than the hole 3, is attached to the outer periphery of the hole 3 on the lower surface of the counter 1, and a waterproof member 6 is installed between the lower surface of the counter 1 and the upper surface of the outer flange 5. intervene,
The inner periphery of the waterproof member 6 is substantially continuous with the inner periphery of the hole 3 of the counter 1, and the tip of the soft tongue piece 7 that protrudes downward from the inner periphery of the waterproof member 6 is attached to the washbowl 4. It is made of elastic contact with the inner surface. That is, in the present invention, the step 12 between the upper end of the inner wall of the washbowl 4 and the lower end of the inner circumference of the hole 3 of the counter 1 is hidden by the tongue piece 7 of the waterproof member 6, and dirt is removed from this part. In addition, the waterproof member 6 itself not only prevents water from leaking from the attachment part of the washbowl 4, but also the tongue piece 7 can prevent water from entering. By doing so, the conventional problems were solved and the above-mentioned purpose of the present invention was achieved.

The present invention will be explained in detail below with reference to Examples. The counter 1 is constructed by forming a decorative layer 10 such as a melamine decorative board on the upper surface of a base material 8 such as plywood. A counter 1 is provided with a hole 3 for attaching a washbowl with a decorative edge 2 on the inner circumference. The decorative edge 2 is for finishing the end of the counter 1, and is formed of hard urethane resin. The upper opening of the washbowl 4 is slightly larger than the hole 3 of the counter 1 (that is, the inner circumference of the decorative edge 2), and an outer flange 5 is provided on the outer circumference of the upper part of the washbowl 4. The waterproof member 6 is formed of urethane resin into an annular shape, and has a tongue piece 7 projecting downward from the inner circumference of the waterproof member 6. Here, at least the tongue piece 7 is soft. Of course, the entire waterproof member 6 may be made of soft urethane resin. Of course, the waterproof member 6 may be formed of a material other than urethane resin. Thus, the outer flange 5 of the washbowl 4 is placed on the outer periphery of the hole 3 on the lower surface of the counter 1 via the waterproof member 6, and in this state the washbowl 4 is attached to the counter 1 using the mounting fittings 11. In this case, the inner periphery of the waterproof member 6 is made to be substantially continuous with the inner periphery of the decorative edge 2 of the hole 3 of the counter 1, and a soft tongue piece 7 protrudes downward from the inner periphery of the waterproof member 6. The tip of the holder is brought into elastic contact with the inner surface of the washbowl 4. As the tongue piece 7 comes into elastic contact with the inner wall of the washbowl 4, it hides the step 12 between the upper end of the inner wall of the washbowl 4 and the lower end of the inner circumference of the hole 3 of the counter 1. . Therefore, in the present invention, the stepped portion 12 is not exposed, and there is no part to which dirt such as water scale may adhere. In the above embodiment, the decorative edge 2 and the waterproof member 6 are separate bodies, but the decorative edge 2 and the waterproof member 6 are integrally formed of urethane resin or the like (even in this case, at least the decorative edge 2 portion is made hard, When the decorative edge 2 is attached to the hole 3 of the counter 1, the waterproof member 6 may be attached to the lower surface of the counter 1 at the same time.

[Effects of the invention] As described above, in the present invention, a waterproof member is interposed between the lower surface of the counter and the upper surface of the outer flange of the washbowl, and the inner circumference of the waterproof member is inserted into the hole of the counter. The tip of the soft tongue piece that is substantially continuous with the inner circumference of the decorative edge and protrudes downward from the inner circumference of the waterproof member is in elastic contact with the inner surface of the washbowl, so that the tongue piece of the waterproof member closes the washbowl. The step between the upper end of the inner wall of the counter and the lower end of the inner periphery of the hole in the counter is hidden to prevent the step, where dirt such as water scale easily adheres, from being exposed to the outside, and to prevent dirt such as water scale from being exposed to the outside. The waterproof member itself not only prevents water from leaking from the washbowl attachment part, but also the tongue piece can prevent water from entering.
