ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
Wash table fittings contain a fitting body intended to be fixed with a standing face to an at least approximately horizontal surface, through which is passed the lead for the fitting. Other fittings can also be installed on planar surfaces. Such fittings are referred to hereinafter as standing fittings.
SUMMARY OF THE INVENTION
The problem of the invention is to so improve a sanitary fitting that it can be more easily installed.
For solving this problem the invention proposes a sanitary fitting having a holding element having a holding tongue.
The holding element, during the manufacture of the fitting, is e.g. inserted from below into the fitting body and fixed. The holding element leaves a passage free for the lead. The holding element is fitted in such a way that the holding tongue is located on the fitting side remote from the center of gravity and normally on the side remote from the discharge spout. On installing the fitting the holding tongue passes through the opening of the fixing surface and can prevent tilting of the fitting, which could occur if the center of gravity of the fitting was outside the standing face. As a function of the strength and surface characteristics of the holding tongue a straight configuration can be sufficient to prevent said tilting. In particular, the holding tongue can be formed by a circumferential portion of a skirt or apron, which passes round part of or the entire circumference. Tilting is prevented by the corresponding dimensioning in that said skirt is only partly deformed.
The fixing to the fitting can e.g. take place by providing a rigid fit along a surface, e.g. a circumferential surface. The holding part is then inserted from below, whilst exerting a force.
Another possibility consists of fixing the holding part by snapping in.
Thus, a deformation and an undercut are used in order to perform the snap-in process.
According to a further development of the invention, on the plate side directed out of the fitting is fitted a spigot, which is smaller than the standard sizes of openings in the basin fixture, wash stand or other surface to which the fitting is to be fitted. The spigot only needs to protrude by a few millimeters. It consequently enables the fitter to align the fitting with respect to the opening without being able to be able to precisely observe it.
The holding tongue can have a projection on its outwardly directed side and this forms a holding shoulder facing the fitting. On tilting the holding shoulder engages on the underside of the wash stand, so that further tilting is prevented.
The holding projection can in particular be located in the vicinity of the end of the holding tongue.
According to the invention, it is also possible for the holding tongue to have several projections, whose length increases with increasing distance of the projection from the plate element. This permits an adaptation to different plate thicknesses. The outside of the holding tongue can have a stepped form.
Another possibility proposed by the invention consists of fitting several juxtaposed holding tongues to the plate.
The holding tongues can have different lengths, e.g. three holding tongues with three different lengths.
It is also possible in the case of several holding tongues, to arrange the projections with different distances from the standing face.
