DESCRIPTION:
BRIEF SUMMARY
The invention relates to a sanitary faucet for surface attachment with a valve housing with at least one ring-shaped preferably circular ring-shaped connection mounting and with a water pipe section inserted with a connection end into the connection mounting, and the water pipe section in the connection mounting is sealed toward the valve housing by a seal and is rigidly connected to the valve housing.
BACKGROUND OF THE INVENTION
Sanitary faucets for surface attachment are known in a multiplicity of embodiments as bath faucets, spray faucets, sink faucets, bidet faucets etc. Such a sanitary faucet normally has a valve housing in which, with modern sanitary faucets, a single-lever mixing system is usually placed. To feed warm and cold water and to draw mixed water, such a valve housing usually has several connection mountings, into which connection ends of corresponding water pipe sections can be inserted. This is performed nowadays usually by having the valve housing in the connection mounting exhibit an inner thread into which the connection end of the water pipe section provided with a corresponding outer thread can be screwed. The seal is made as a pressure-stressed sealing ring in a way known in sanitary plumbing engineering.
The above-explained screw connections provided in previously known sanitary faucets of the type in question use much material because the wall thickness of the valve housing and of the water pipe sections must permit applying the threads. Further, the production technique is expensive with the requirement of cutting corresponding threads, etc.
SUMMARY OF THE INVENTION
The object of the invention is to indicate a sanitary faucet of the type in question that overall is made, and can be produced, more simply.
The object indicated above is achieved according to the teaching of the invention in that the water pipe section is only inserted with its connection end into the connection mounting and exhibits on the connection end at least one locking notch running essentially perpendicular to the insertion direction, preferably approximately tangential, in that in the valve housing there is provided at least one locking bore running essentially perpendicular to the insertion direction, preferably approximately tangential to the connection mounting, and leading into the connection mounting, in that when the locking notch and the locking bore are aligned, a locking pin, preferably a tangent pin can be inserted into the locking bore and further into the locking notch and in that, when the tangent pin is inserted, the water pipe section is rigidly connected to the valve housing. The essential core of the teaching of the invention is dispensing with a screw connection at the indicated points. Instead, a pin connection is made, which is considerably simpler in terms of production and is more cost effective. Relative to the material wall thicknesses, it is also more advantageous than a screw connection. Normally, a single locking pin suffices; but if greater operational stresses are expected, several locking pins placed distributed on the periphery of the connection mounting can be inserted. Depending on the configuration of the flow channel in the water pipe section, there are various arrangement possibilities for the locking pin. It can be made, for example, as a transverse pin, i.e., run transversely through the water pipe section. That is especially suitable with respect to attachment and to durability, but is unfavorable with respect to flow. Consequently, it is especially advisable to make the locking pin as a tangent pin and to orient the locking notch and the locking bore correspondingly.
Other preferred features include the fact that the locking pin, preferably made as a tangent pin, is made as a soldering pin and thus the connection end is rigidly connected to the valve housing by an interior brazing connection. The tangent pin here is used only temporarily mechanically to connect the connection end of the water pipe section to the valve housing. The actual operational, mechanical
