Description

[Detailed description of the invention] The present invention relates to a structure for fixing the washbasin bowl of a washbasin unit. Synthetic resin dowels 2, 2... are bored on both upper edges of the cabinet 1, and flanges formed on the lower surfaces of both sides of the washbasin bowl 3. 4, 4 with dowel fitting holes 5, 5
The flanges 4, 4 of the washing bowl 3 are placed on the upper edges of both sides of the cabinet 1 via the double-sided adhesive tape 7 with dowel insertion holes 6, 6, . . . 2... into the dowel insertion holes 6, 6... of the double-sided adhesive tape 7, and pass the tops of the dowels 2, 2... into the dowel fitting holes 5, 5... of the flanges 4, 4, and , 2 . . . are melted and the upper portions of the dowels 2 , 2 .

When assembling the washbasin unit by attaching the washbasin bowl 3 to the cabinet 1, if the cabinet 1 is made of resin molding, the wall thickness is thin, so conventionally the washbowl 3 is attached to the top of the cabinet 1 with an L-shaped cross section. The piece 8 is fixed, and as shown in FIG. I tried to keep ball 3 fixed. However, in this case, the washbasin bowl 3 is simply fixed to the cabinet 1 with adhesive force, so the washbasin unit is packed in a packaging box 10 having a pad 9 as shown in FIG. Stack them horizontally and store them as shown in b. During transportation, if a load W is applied from above as shown in FIG. 3C, there is a risk that the washbowl 3 and the cabinet 1 will be displaced by this load W. Furthermore, when the washbasin unit is installed as shown in Fig. 3a, in areas with high water pressure, the water tap 14 is attached to the heliuse pipe 11 via a cap nut 12 and a rubber gasket 13 as shown in Fig. 3c.
There is a risk that the faucet 14 may be pushed up by water pressure and disconnected from the hose pipe 11, but since the wash bowl 3 is simply fixed to the cabinet 1 with adhesive force, the double-sided adhesive tape 7 may peel off. There was also the problem that the washing bowl 3 rose above the cabinet 1 as shown in FIG. 3b.

The present invention has been made in view of the above points, and provides a washbasin bowl fixing structure for a washbasin unit that does not have the risk of the washbasin being dislocated from the cabinet or being lifted up from the cabinet. The purpose is to provide

The present invention will be explained in detail below with reference to Examples. The cabinet 1 is made of a synthetic resin molded product and is formed into a thin box shape, and on the inner side of the upper edge of the opening of the side plate is a mounting piece 8 that is also made of a thermoplastic synthetic resin molded product and has an L-shaped cross section. As shown in FIG. 4, they are fixed by means of fusion, adhesion, etc. A plurality of dowels 2 which are integrally molded with the mounting piece 8 and made of synthetic resin are protruded from the upper surface of the mounting piece 8. The wash basin 3 is made of enameled steel plate, and has a flange 4 extending from its lower surface.
An engagement hole 5 is provided at a position corresponding to the dowel 2. The engagement hole 5 may be formed by being cut out from the side end of the flange 4, or may be formed as a hole that opens only in the top and bottom. Further, the double-sided adhesive tape 7, which has adhesive layers on both upper and lower surfaces, is provided with dowel insertion holes 6 at positions corresponding to the dowels 2.

When installing the washing bowl 3 on the cabinet 1, the double-sided adhesive tape 7 is pasted on the mounting piece 8 of the cabinet 1 so that the dowel 2 passes through the dowel insertion hole 6. Next, the flange 4 of the toilet bowl 3 is pasted onto the double-sided adhesive tape 7 by passing the dowel 2 through the engagement hole 5 as shown in FIG. 5a. Thereafter, the upper part of the synthetic resin dowel 2 is melted and crushed by ultrasonic heating, and the protrusion 15 formed at the upper end of the dowel 2 is locked to the upper surface of the flange 4 at the peripheral edge of the engagement hole 5. Along with this protrusion 1
5 is fused to the flange 4. In this way, by inserting the dowels 2 into the engagement holes 5 of the flanges 4, 4 on both sides of the washbasin bowl 3, it is possible to prevent the mounting position of the washbasin bowl 3 on the cabinet 1 from shifting. By melting the upper end of the dowel 2 and locking it in the engagement hole 5, the washing bowl 3 can be prevented from floating up from the cabinet 1.

As mentioned above, according to the present invention, even if the washbasin unit is loaded horizontally and load is applied, it is possible to prevent the installation position of the washbowl from shifting to the cabinet, and it is also possible to prevent the installation position of the washbowl from shifting in the cabinet in areas with high water pressure. Even if a pushing force is applied, there is no fear that the wash bowl will come up from the cabinet.

Claims (1)

[Scope of utility model registration request] Protrude synthetic resin dowels on the upper edges of both sides of the cabinet, drill dowel fitting holes in the flanges formed on the lower surfaces of both sides of the washbasin bowl, and attach the dowels to the upper edges of both sides of the cabinet via double-sided adhesive tape with holes drilled through the dowel insertion holes. Place the flange of the wash bowl on the edge, insert the dowel into the dowel insertion hole of the double-sided adhesive tape, pass the top of the dowel through the dowel engagement hole of the flange, and melt the top of the dowel to remove the top of the dowel. The washbowl fixing structure of the washbasin unit consists of a dowel engagement hole that is secured to the top surface of the periphery of the dowel engagement hole.
