Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for fixing a washbasin to a washstand counter from the bottom side thereof.

[Conventional technology]

FIG. 5 is a plan view of a conventional mounting situation in which the wash basin 24 is fixed to the lower surface of the wash counter 22. The washstand counter 22 is attached to the wall surface 21 with one or both of its side ends 22a and rear end 22b supported by brackets 23, 23, etc., respectively. The washstand counter 22 has an opening 27 having a shape corresponding to the bowl 25 of the washbasin 24. The washbasin 24 has a basin part 25 aligned with this opening 27, and a fixture 3.
0 to the lower surface of the washroom counter 22.

FIG. 6 shows details of the mounting structure of the washbasin 24 in cross section. On the bottom surface of the washstand counter 22 attached to the wall surface 21 with a bracket 23,
A mounting portion 33 is formed of a boss protuberance 31 and a sleeve nut 32 embedded within the boss protuberance 31. The fixture 30 for the washbasin 24 is made up of a retaining plate 34 and a bolt 35, and the retaining plate 34 is inserted into the through hole 34a of the retaining plate 34 and screwed into the mounting portion 33. A board 34 is fastened to the lower surface of the washroom counter 22. Usually, the washbasin 24 has a flange 26 formed at the upper edge of the bowl 25 thereof. Therefore, the holding plate 3
The washbasin 24 is fixed to the washbasin counter 22 from the underside by sandwiching the flange 26 between the sink counter 4 and the underside 22a of the washstand counter and tightening the bolts 35. Furthermore, a sealing material 36 for preventing water leakage is interposed between the flange 26 of the washbasin 24 and the washstand counter 22.

[Problem that the invention attempts to solve]

In the conventional mounting structure described above, as shown in FIG.
is supported in a cantilevered state. Therefore, the holding plate 3
4 is subjected to bending stress due to the load of the washbasin 24. In addition, when water is stored in the pot 25 or the user touches the pot 25, the bending stress described above becomes even greater. As a result, the retaining plate 34 may bend or the bolt fixing portion may become distorted, creating a gap between the washstand counter 22 and the washbasin 24, which may cause water leakage or damage to the washbasin 24.
This has the disadvantage of causing rattling, etc.

Further, since the flange portions 26 of the washbasin 24 overlap so as to occupy a wide area around the opening 27 of the washstand counter 22, there is a problem that the area where faucet fittings etc. can be installed is narrowed.
This will be explained with reference to the plan view of FIG. 5. Normally, faucet fittings and the like are installed in the rear region 40 of the washstand counter 22. In this rear area 40, a faucet or the like cannot be installed in the part where the flange 26 of the washbasin 24 overlaps the washstand counter 22.
In particular, the width dimension d of the central region, which is optimal for installing a faucet fitting, becomes smaller. Therefore, the work of installing the faucet fittings was difficult. Moreover, the installation position of the faucet fitting is at least separated from the bowl part 25 of the washbasin 24 by the width of the flange part 26. As a result, the distance from the water supply pipe to the sink counter 22 to the water outlet becomes longer, which not only makes it impossible to use faucets with short necks, but also increases the distance between the faucet and the user, causing inconvenience. let

Further, faucet fittings and the like cannot be installed in the portion where the fitting 30 is provided. Incidentally, in order to securely attach the washbasin 24, it is desirable to increase the size of the fixture 30. This causes various problems such as the overlapping dimension (dimension L in FIG. 6) with the washbasin counter 22 (dimension L in FIG. 6), which causes the fixture 30 to also become an obstacle when installing faucet fittings and the like.

[Means for solving problems]

The present invention provides a mounting structure for a washbasin that can securely fix the washbasin to the washstand counter and also secure a wide area in which faucet fittings and the like can be installed. The feature is that the washbasin can be attached to the sink counter from the bottom side, and the rear part of the washbasin is provided with a hollow projecting edge with a through hole for bolt insertion, and the back of the projecting edge is The end is formed into a flat surface for the washbasin to stand on its own, and the washbasin is fixed to the underside of the washstand by bolts inserted through the through holes in the overhanging edge and suspended from the underside of the washstand. .

[Effect]

With the above configuration, the overhanging edge of the washbasin is directly fixed to the underside of the washstand by bolts. Therefore, since only tensile stress acts on the bolt, the fixed state is extremely stable. Since the bolts pass through the hollow projecting edge at two locations, the washbasin can be accurately positioned with respect to the washstand counter. Furthermore, even if the bolts become loose, the washbasin will not wobble.

Since the rear end of the overhanging edge provided at the rear of the washbasin is a flat surface, the overlapping area between the washbasin and the washstand is smaller than before, and therefore,
The rear area of the wash basin on the wash counter can be widened. That is, it is possible to secure a wide area of the washstand counter that can be used for installing faucet fittings and the like.

Furthermore, the washbasin used in the present invention has a structure that has a flat surface at the rear end, and the washbasin can stand on its own with this as the bottom surface. Therefore, when baking the wash basin, it is possible to place it vertically, occupying less space.

〔Example〕

FIG. 1 shows a cross-sectional view of the main parts of an embodiment of the present invention.

As shown in the figure, a washstand counter 1 is fixed to a wall surface 2 with brackets 4 and the like. A boss protrusion 5 is provided on the lower surface 1a of the washstand counter 1, and a mounting portion 7 is formed by embedding an embedded nut 6 having a flange on the outer periphery of the upper end. At the rear of the washbasin 3, a hollow projecting edge 8 is formed on the outer surface side of the bowl portion 12, and the projecting edge 8 has a rear end formed into a flat surface 13 and A through hole 10 is provided that passes through the top and bottom. Insert the stud bolt 9 into the through hole 10, screw the threaded part 9a at one end into the mounting part 7, make the threaded part 9b at the other end protrude from the lower surface 8a of the overhanging edge of the washbasin 3, and tighten the holding nut. 11 and tightening the holding nut 11, the washbasin 3 is fixed to the lower surface side of the washstand counter 1. In this embodiment, a double-threaded stud bolt 9 is used.
Instead of this, it is of course possible to screw in and use a regular bolt with a hexagonal head, and any other stud bolt other than the stud nut 6 may be used.

The washbasin 3 used in the mounting structure according to the present invention is
It does not have a flange for fixing to the lower surface 1a of the counter, but instead has a flat surface 13 at the rear end (see FIG. 2). By using the washbasin 3 in such a shape, the dimension l of the portion where the washstand counter 1 and the washbasin 3 overlap (see Figure 1)
can be made smaller. Faucet fittings etc.
As shown in the figure, since it is installed in the rear area 20 of the wash basin 3 on the wash counter 1, the above-mentioned dimension 1 becomes smaller, so that the area where faucet fittings etc. can be installed becomes wider. In particular, since the width b of the central portion of the rear region 20 is increased, installation of faucet fittings and the like is extremely easy. Moreover,
Since the faucet fittings can be installed very close to the bowl part 12 of the washbasin 3, it can be used even if the faucet neck is short, and the distance between the faucet and the user is shortened. Therefore, it has good operability.

As described above, by adopting the mounting structure according to the present invention, not only the mounting state of the washbasin 3 is strengthened, but also the mounting structure for the washbasin 3 that was conventionally
0 (see FIGS. 5 and 6) is no longer necessary, so the usable area of the washstand counter 1 is expanded.

By the way, the washbasin 3 according to the present invention has a flat surface 13 at the rear end, and as shown in FIG. Can be fired. According to this firing method, since the area occupied by each washbasin 3 is reduced, the number of pieces to be fired per process can be increased, and costs can be reduced through mass production. In addition, vertical firing improves thermal efficiency due to less ground contact area, reducing uneven firing.
This results in improved quality and increased yield.

In addition to the above-mentioned embodiments of the present invention,
Various applications are possible. For example, in the embodiment shown in FIG. 3, the washbasin 3 according to the present invention is fixed at four symmetrical locations, but the fixing locations and the number of fixing locations can be changed as appropriate. It is. In addition, the mounting structure according to the present invention only needs to be installed on the rear side of the washbasin, which requires the most strength, and the front side does not interfere with the installation of faucet fittings, etc., and is more durable than the rear side. Since the load is small, it does not prevent the use of a conventional mounting structure using a holding plate. In this way, the present invention can be modified as appropriate depending on the mode of implementation.

[Effect of idea]

As explained above, according to the present invention, the mounting condition of the washbasin is strong, so it does not cause the washbasin to wobble or create a gap between the washbasin and the washstand counter, causing water leakage. There is nothing to do. Furthermore, since the bolts vertically disposed on the underside of the washbasin counter penetrate through two hollow projecting edges provided on the washbasin, the washbasin can be accurately positioned with respect to the washstand. Further, even if the bolt is loosened, the washbasin will be less likely to rattle.

Since the washbasin used in the mounting structure according to the present invention has a flat surface formed at the rear end, the washbasin can stand on its own by using this as the bottom surface. Therefore,
Compared to conventional horizontal placement, each washbasin occupies a much smaller area and can be fired vertically. Therefore, it is possible to simultaneously fire a much larger number of products than in the past, resulting in lower firing costs. Furthermore, thermal efficiency is improved by reducing the ground contact area of the washbasin, thereby reducing uneven firing, resulting in improved quality and increased yield.

Furthermore, by forming a flat surface at the rear end of the washbasin, the rear area of the washbasin on the washstand becomes wider, and the area that can be effectively used on the washstand is expanded more than before. Since this area is used for installing faucet fittings, etc., installation work for faucet fittings, etc. is facilitated. Further, since the faucet fittings and the like can be placed in a position on the front side where the user can easily operate the faucet fittings, an excellent usability can be obtained.
