Description

[Detailed explanation of the idea] (b) Industrial application fields This invention relates to a shelf mounting structure for a washbasin.

(b) Conventional technology Conventionally, in a washstand in which a shelf or a mirror, etc. is placed on the upper surface of the inner part of the washbowl, when connecting and fixing the washbowl and the shelf, etc. The structure was such that a substantially rectangular metal piece c was stretched across the backs of the bowl a and the shelf b, etc., and the wash basin, shelf, etc. were fixed to the metal piece c with bolts d or the like.

(c) Problems that the invention aims to solve However, it is necessary for the back of the washstand e to be in close contact with the wall f of the room in which the washstand is installed, and for this reason, the thickness of the strip-shaped metal piece c is reduced. As a result, the same metal piece c becomes easy to bend, and the shelf b/
There was a drawback that the fixation of mirrors etc. became unstable.
In addition, in order to solve this drawback, it is possible to fix the upper part of the shelf b, mirror, etc. to the back wall f, but in this case, extra fixing work is required and the washbasin e
The installation work became complicated, and after the same unit was removed,
Installation marks such as holes for the above-mentioned fixing remain on the wall f,
There was a drawback that the wall f required repair. Furthermore, in these fixed structures, the wash basin a and the shelf b
A gap is likely to be created between the shelf b and the shelf b, and water enters this gap during washing and stains the wall f on the back side of the shelf b.
There was also a risk that it would cause corrosion.

(d) Means for solving the problem In this invention, the inner wall of the washbasin of the washstand is extended upward to form a rising wall, and a shelf is mounted on the top surface of the rising wall in surface contact. The purpose of the present invention is to provide a shelf mounting structure for a washbasin in which the upper surface of a rising wall and a shelf are tightened and fixed from above and below using washbasin operation fittings.

(E) Effect In this design, a mounting surface for mounting a shelf, etc. is formed at a high position at the back of the washbasin, that is, on the top surface of the rising wall. The washbasin and shelf are in contact with each other over a wide area, and the shelf is fastened to the top of the wall rising from above and below using washbasin operation fittings such as hot water mixers, switching faucets, shower equipment, pop-up handles, etc. When the shelf is attached and fixed to the washbowl in this way, the rising wall at the back of the washbowl and the mounting part of the shelf are in surface contact, so it is difficult for water to enter the boundary area. In addition, since the shelves are placed at a high position, water from washing the toilet is less likely to splash onto the shelves, and the shelf installation structure is simple and stable. The bolts are tightened and fixed from above and below in a state of surface contact, making it possible to create an integrally strong construction state.

(f) Effects According to this invention, since the shelves are mounted on the rising wall that extends upward, the shelves can be placed as high as possible, reducing the amount of water splashed during washing etc. Not only can the shelf be prevented from getting dirty, but the contact area between the washbowl and the shelf can be widened.Furthermore, since the washbasin operation fittings are used to tighten and fix from above and below, the shelf can be easily fixed without worrying about a simple structure. It can be firmly and stably fixed to the washbowl with surface contact, and furthermore, the contact area between the washbowl and the shelf is in close contact, making it difficult for water to enter, preventing corrosion of the wall surface. There is no need for separate parts or work to fix the unit to the wall, which simplifies the installation work of the unit, and also leaves no traces of attachment to the wall, making it easy to remove the unit. The effect is that there is no need to repair the installation marks on the wall afterwards.
