Abstract

A faucet with a faucet housing, a tubular fastening device that is fastenable in a tap hole of a faucet carrier, and one or more flexible connection lines extending through the tubular fastening device to the faucet housing. The tubular fastening device has a tube section that is insertable into the tap hole, a flange that is placeable upon the faucet carrier, as well as an annular collar projecting beyond the flange, on which the faucet housing is fastened. At least two pivotal, longitudinally adjustable fastening clamps are arranged laterally at the tube section, which are adjustable via clamping screws operated from the faucet side against the bottom of the faucet carrier. The fastening clamps are received in the assembled stated in recesses of the fastening device, and pivot therefrom into a fastening position upon operation of clamping screws. The faucet housing has at the fastening side a receiving socket for a form-fitting, torque-proof reception of an annular collar of the tubular fastening device. The faucet is mountable in the pre-assembled state, by the faucet housing with the connection lines, connected thereto and guided through the tubular fastening device, being lifted off the tubular fastening device, inserted in the tap hole, to such an extent that the clamping screws are accessible.

First claim

The invention claimed is:

1. A faucet comprising a faucet housing ( 11 ) including a control valve and an outlet of the faucet, a tubular fastening device ( 1 ) which is fastenable in a tap hole ( 10 ′) of a faucet carrier ( 10 ), and one or more flexible connection lines ( 12 ) extending through the tubular fastening device ( 1 ) to the faucet housing ( 11 ), the faucet housing being in a pre-assembled state with the one or more flexible connection lines ( 12 );
the tubular fastening device ( 1 ) comprises a tube section ( 2 ) that is insertable into the tap hole ( 10 ′), a flange ( 3 ) that is placeable upon the faucet carrier ( 10 ), and an annular collar ( 4 ) projecting beyond the flange ( 3 ), on which the faucet housing ( 11 ) is fastenable,
at least two fastening clamps ( 5 ) arranged laterally at the tubular section ( 2 ) which are pivotable and longitudinally adjustable, that are adjustable in reference to a bottom of the faucet carrier ( 10 ) via clamping screws ( 6 ) extending inside the tubular fastening device ( 1 ), with the clamping screws ( 6 ) being operable from a faucet side of the fastening device ( 1 ),
the faucet housing ( 11 ) comprises at a fastening side a receiving socket ( 13 ) for form-fitting and non-rotatable plug-in reception of the annular collar ( 4 ) of the tubular fastening device ( 1 ) via insertion in an axial direction of the tubular fastening device, the faucet in the pre-assembled state is fastenable on the faucet carrier ( 10 ), and the faucet housing ( 11 ) with the connection lines ( 12 ), connected thereto and guided through the tubular fastening device ( 1 ) are lifted off the tubular fastening device ( 1 ) insertable in the tap hole ( 10 ′) to such an extent that the clamping screws ( 6 ) are accessible.

2. The faucet according to claim 1 , wherein the fastening clamps ( 5 ) are accepted in an assembled position in recesses ( 8 ) of the fastening device ( 1 ) from which they pivot out into a fastening position upon operation of the clamping screws ( 6 ).

3. The faucet according to claim 1 , wherein the faucet housing ( 11 ) comprises an outlet with a pull-out sprayer, which is connected via a pull-out hose extending through the faucet housing ( 11 ) to the faucet housing, with the pull-out hose extending through the tubular fastening device ( 1 ) and in a loop back to a connection at the faucet housing ( 11 ).

4. The faucet according to claim 1 , wherein the collar ( 4 ) of the fastening device ( 1 ) comprises a groove ( 4 ′) and the faucet housing ( 11 ) comprises a corresponding projection ( 13 ′) arranged inside the receiving socket ( 13 ).

5. The faucet according to claim 4 , wherein the faucet housing ( 11 ) includes a fastening screw in an area of the receiving socket ( 13 ) to fasten the faucet housing ( 11 ) plugged onto the collar ( 4 ).

6. The faucet according to claim 5 , wherein the fastening screw extends through the projection ( 13 ′).

7. The faucet according to claim 1 , wherein the receiving socket ( 13 ) and the collar ( 4 ) cooperate such that the faucet housing ( 11 ) is plugged onto the collar ( 4 ) in an axial direction in reference to the tubular fastening device ( 1 ).

8. The faucet according to claim 1 , wherein the flange ( 3 ) has at one side a straight formed edge section ( 9 ) for visual alignment of the fastening device ( 1 ) in reference to an edge of a kitchen sink serving as the faucet carrier ( 10 ).

9. The faucet according to claim 1 , wherein the faucet housing ( 1 ) includes a mixing valve, and the connection lines ( 12 ) comprise a warm water and a cold water line.
