7. The sanitary faucet (1) according to claim 5, comprising at least one backflow preventer (18) by means of which a backflow of a liquid into at least one supply channel (6, 7) of the fastener (1) can be at least partially prevented.

8. A method for securing a sanitary faucet (2) to a support (5), comprising the following steps: a) securing the fastener (1) according to claim 1 to the support (5); and b) securing the sanitary faucet (2) to the fastener (1), whereby at least one valve (8, 9) of the fastener (1) opens at least one supply channel (6, 7) of the fastener (1).

Description

(1) The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but the invention is not limited thereto. The same reference numerals are used for the same components in the figures. In an exemplary and schematic manner,

(2) FIG. 1 shows a side view of a sanitary faucet;

(3) FIG. 2 shows a longitudinal section of the sanitary faucet before its attachment to a support; and

(4) FIG. 3 shows a longitudinal section of the sanitary faucet while it is being secured to the support.

(5) FIG. 1 shows a side view of the sanitary faucet 2. The sanitary faucet 2 has a faucet body 15, at the outlet 16 of which an outlet opening 19 is formed. Furthermore, the sanitary faucet 2 has a control element 20, which can be used to control a delivery of a liquid via the outlet opening 19. A fastener 1 is used to detachably secure the sanitary faucet 2 to a support 5 shown in FIGS. 2 and 3.

(6) FIG. 2 shows a longitudinal section of the sanitary faucet 2 before its attachment to the support 5 in the area 21 shown in FIG. 1. The support 5 has an opening 4, in which a fastener 1 is secured. For this purpose, the fastener 1 has an annular locking element 14 with a snap hook 23 on an outer surface 22 of a coupling body 3. The locking element 14 can be adjusted along the outer surface 22 of the coupling body 3 against a lower surface 24 of the support 5, such that the coupling body 3 can be tightly secured in the opening 4. A first supply channel 6 and a second supply channel 7 are formed in the coupling body 3, which supply channels open into a mount 13 of the coupling body 3 for the sanitary faucet 2. Cold water can be supplied to the sanitary faucet 2 via the first supply channel 6 and hot water via the second supply channel 7. For this purpose, the fastener 1 can be connected to supply lines for the cold water and hot water, which are not shown here. A first valve 8 is arranged in the first supply channel 6, which closes the first supply channel 6 when the sanitary faucet 2 is not secured to the coupling body 3. For this purpose, the first valve 8 has a valve body 10 which is pressed against a valve seat 12 formed on the coupling housing 3 by a spring 11. A second valve 9 identical to the first valve 8 is arranged in the second supply channel 7. When the sanitary faucet 2 is inserted into the mount 13 of the coupling housing 3, the valve bodies 10 of the valves 8, 9 are pushed away from the valve seats 12 by connecting nipples 25 of an adapter 17 of the sanitary faucet 2, and the valve bodies 10 of the valves 8, 9 are moved to an open position. To illustrate this open position, the second valve 9 is shown with a valve body 10 lifted off the valve seat 12.

(7) FIG. 3 shows the same longitudinal section as in FIG. 2 of the sanitary faucet 2 in its attachment to the support 5. In FIG. 3, the sanitary faucet 2 and the adapter 17 have been inserted into the mount 13 of the coupling housing 3 until the connecting nipples 25 of the adapter 17 reach an end face 26 of the valve body 10. When the sanitary faucet 2 is further inserted into the fastener 1 until the adapter 17 is seated on a bottom 27 of the mount 13, the valve bodies 10 of the first valve seat 8 and second valve seat 9 are moved from the valve seats 12 to an open position. This open position is shown for the second valve 9. In the open position, the sanitary faucet 2 can be supplied with cold water via the first supply channel 6 and with hot water via the second supply channel 7. The faucet body 15 of the sanitary faucet 2 can then be screwed/bolted to the fastener 1, such that the sanitary faucet 2 is secured to the support 5. When the sanitary faucet 2 is re-detached from the fastener 1 and the adapter 17 is pulled out of the mount 13, the valve bodies 10 are automatically again pressed against the valve seats 12 by the springs 11, closing the first supply channel 6 and the second supply channel 7. In the adapter 10, one backflow preventer 18 is arranged in a first liquid channel 28 for the cold water and in a second liquid channel 29 for the hot water, respectively, which prevent the cold water and hot water from escaping via the connecting nipples 25 when the sanitary faucet 2 is detached.

(8) The fastener 1 can be used to detach the sanitary faucet 2 from the support with little effort, i.e., the support can be cleaned more easily.
