Faucet with a quick fastening device

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) FIGS. 1 to 3 show a quick fastening device for the use with a faucet according to the invention. This represents a tubular fastening part 2, which has in the upper section a flange 3 and an annular collar 4 abutting thereto. Two pivotal fastening clamps 5 are provided at the side of the tube section 2, each adjustable in the axial direction via a clamping screw 6. The clamping screw 6 is located inside the tubular fastening device 1 and the fastening clamps 5 project in the pivoted-out state through slot-shaped openings 7 out of the tubular section 2 towards the outside. In the assembled position shown in FIGS. 1 and 2 the fastening clamps are pivoted inwardly into respective recesses 8, so that they are located inside the perimeter of the tubular section 2. Alternatively the fastening clamps may also be arranged in the assembled position inside its circumference underneath the tubular section 2 in a virtual extension.

(14) In the exemplary embodiment the pivotal motion of the fastening clamps occurs in a radial plane. However it is just as well possible and included in the scope of the present invention that the fastening clamps 5 during operation of the clamping screws fold in a tipping motion out of a vertical into a horizontal direction. The pivoting out of the fastening clamps 5, which may also be a folding out in the above-mentioned sense, can occur, like in the exemplary embodiment, due to friction forces in the thread of the clamping screw 6. Similarly, it is also possible to provide springs, which apply a force in the pivotal direction upon the fastening clamps 5, or to provide wedge-shaped extending guides at the tubular section 2 and/or the recesses 8 so that the pivoting of the fastening clamps 5 occurs based on the wedge-effect by the clamping screws 6 during the axial adjustment.

(15) For the assembly, the tubular section 2 with the fastening clamps 5, pivoted inwardly in the assembled position, can be plugged through a tap hole of a faucet carrier 10, such as a kitchen sink, a countertop, or a wash basin. The flange 3 comprises at one side a straight section 9, which serves as an alignment mark and allows an alignment of the fastening device 1 in reference to the faucet carrier. Subsequently the fastening screws 6 are tightened from the top. Here, initially the fastening clamps 5 pivot outwardly due to the friction in the internal thread until they are abutting the slot-shaped opening 7 at the edge. The pivoted-out position of the fastening clamps 5 is here also called the fastening position, because in this position the fastening device 1 can be held via the fastening clamps 5 and their clamping screws 6 against the faucet carrier 10. By another operation of the clamping screws 6 the fastening clamps 5 are now adjusted upwards in the direction of the flange 3 until they contact the bottom of the faucet carrier. The fastening screws 5 therefore fix via the clamping screws 6 the flange 3 of the fastening device in reference to the faucet carrier 10. This position is shown in FIG. 3.

(16) According to the present invention, the fastening device 1 is however not installed separately from the faucet in the tap hole, but the faucet is mounted in the pre-assembled state, thus with the connection lines already connected and guided through the fastening device 1. An exemplary embodiment of such a pre-assembled faucet in an assembled state is shown in FIG. 4. The faucet shows, in addition to the fastening device 1, a faucet housing 11 with connection lines 12 connected thereto. The connection lines 12 are guided through the tubular fastening device 1. At the end of the connection lines 12, facing away from the faucet housing 11, conventional connection sockets with cap nuts are provided for connecting to angle valves of conventional design, which are not shown in the drawings. At its bottom end, the faucet housing comprises a socket 13 which is formed to receive the annular collar 4 of the fastening device 1. The receiving socket 13 and the collar 4 form a fitting, which is sized such that the parts can be inserted into each other manually without play.

(17) For the assembly the fastening device 1, as shown in FIG. 4, is removed from the faucet housing 11 and inserted into the tap hole 10 of the faucet carrier 10. This state is shown in FIG. 5. Subsequently, with an assembly tool for screws 14, as shown in FIG. 6, for example a screwdriver or a battery-operated screwdriver, the fastening screws are tightened and thus the fastening clamps 5 are initially pivoted out and then tightened towards the bottom of the faucet carrier 10. FIG. 7a shows in a view diagonally from the bottom the pivoting out of the frontal fastening clamp 5. By another operation of the corresponding fastening screw the fastening clamp 5 is adjusted to the position shown in FIG. 7b at the bottom of the faucet carrier 10 and tightened thereto.

(18) Now the faucet housing 11 is placed onto the fastening device 1, anchored with the help of fastening screws and corresponding fastening clamps in the tap hole 10 of the faucet carrier 10. The plug-in connection between the end collar 4 of the fastening device and the socket 13 of the faucet housing is embodied in a non-rotatable fashion. For this purpose, a groove 4 is provided in the collar 4 of the fastening device, which extends in the direction of the axial extension of the tubular fastening device 1. A projection 13 at the interior of the receiving socket 13 of the faucet housing 11 engages the groove 4 and this way prevents any rotation of the faucet housing 11 on the collar 4. The projection 13 has a radially extending threaded bore, into which a set screw is screwed to secure the faucet housing, as shown in FIG. 8. A cross-section through the faucet housing 11 and the collar 4 at the elevation of the fastening screw is shown in FIG. 9. The fastening screws 6 are guided through the axially extending bores 6. The connection lines 11 extend in the hollow interior of the fastening device 1.

(19) The lower end of the faucet housing 11 is formed by a radial projection 13 showing an enlarged interior diameter, which serves as a cover like a push-in rosette for the flange 3 of the fastening device 1.
