Abstract
A sanitary single-lever mixer comprising a housing, known per se, having a receiving compartment which is open towards the top. The housing is associated with a closing part which covers the upper opening of the receiving compartment and comprises a center passage. The adjusting lever or the handle extends through said passage. The closing part has a convex, spherical top when seen from above. The handle is associated with a cover element that has an outer exposed part with an exposed surface and a sliding element connected to the exposed part.
Claims8
A sanitary single-lever mixer comprising,
- a) a housing which has a receiving compartment which has an upper aperture;
- b) an adjusting lever for adjusting a flow of water which extends upwards and can be tilted about two axes which are perpendicular to one another;
- c) a handle which is connected, at one end, to the adjusting lever;
- d) a closing part which is associated with the housing, covers the upper aperture and has a central through-aperture through which the adjusting lever or the handle extends, and which closing part possesses an upper side which, viewed from above, is convex and spherical;
- and,
- e) a covering part which is associated with the handle and faces the upper side of the closing part and has an underside which is spherical and essentially complementary to the upper side of the closing part and slides on said upper side when the handle moves;
- wherein
- f) the covering part associated with the handle is made up of an outer, visible part which is provided with a visible surface, and a sliding part which is connected to said visible part, and on which the spherical underside of said covering part is constructed;
- and,
- g) the visible part of the covering part projects beyond the sliding part in a radial direction by means of a protruding rim but maintains a distance from the upper side of the closing part at the protruding rim.

- and,
- e) a covering part which is associated with the handle faces the upper side of the closing part and has an underside which is spherical and essentially complementary to the upper side of the closing part and slides on said upper side when the handle moves;
- wherein
- f) the covering part covers a fraction of the closing part only such that in every position of the adjusting lever a fraction of the convex spherical upper side of the closing part remains visible,
- g) the covering part associated with the handle is made up of an outer visible part having a visible surface and a sliding part which is connected to said visible part and comprising the spherical underside of said covering part.
