[0005] This is aided by a device for attaching a sanitary fitting to a support, which has at least the following features: - a base to which the sanitary fitting can be attached; - a shaft that is connected to the base; - a fastening element for attaching the device to the support; - a fluid valve located in the shaft or fastening element; and - at least one water guide attached to the liquid valve and extending at least partially through the shaft, wherein the liquid valve can be adjusted into an open position and a closed position by means of the at least one water guide.

[0006] Sanitary fittings can be, in particular, kitchen sink fittings, washbasin fittings, and / or window fittings. Sanitary fittings primarily serve to provide a liquid, such as water, at a sink or washbasin as needed. A sanitary fitting can include a fitting body, which may be made, at least partially, of plastic and / or (cast) metal, such as brass. The fitting body may have a (protruding or branching) spout that is rigidly or movably connected to the fitting body. The spout may be at least partially tubular or hose-like. The fitting body or spout has at least one outlet for the liquid. This outlet may, for example, be designed as or include a jet or aerator.The liquid can be discharged, for example, into the surrounding area of ​​the sanitary fitting via at least one outlet opening.

[0007] The sanitary fitting can include a mixing valve for mixing cold water at a specific temperature and hot water at a specific temperature to produce a mixture at a desired temperature. The cold water temperature is particularly at most 25 °C, preferably 1 °C to 25 °C, and more preferably 5 °C to 20 °C, and / or the hot water temperature is particularly at most 90 °C, preferably 25 °C to 90 °C, and more preferably 55 °C to 65 °C. The mixing valve can, for example, be designed as a mixing cartridge and / or be at least partially located within the fitting body of the sanitary fitting.

[0008] The device allows the sanitary fitting to be attached to the support structure, which could be, for example, a sink, washbasin, or worktop. The support structure may have a mounting opening for the device and / or the sanitary fitting. The mounting opening may extend, in particular completely, through the support structure. The mounting opening may extend along a longitudinal axis. The device may be a quick-release fastener for the sanitary fitting.

[0009] The device comprises a base to which the sanitary fitting can be attached, for example, via a bayonet connection. The base can be made at least partially of plastic and / or metal. The base can be at least partially sleeve-shaped or tubular. The base can extend along a longitudinal axis. The base can have a length of, for example, 10 mm to 50 mm (particularly parallel to the longitudinal axis), an inner diameter of 20 mm to 60 mm (particularly perpendicular to the longitudinal axis), and / or an outer diameter of 22 mm to 70 mm (particularly perpendicular to the longitudinal axis). The base can have an internal thread. The base can be arranged or attached to a top surface of the support. The base can be arranged on the mounting opening and / or coaxially with the mounting opening, such that the longitudinal axis runs parallel or coaxially with the longitudinal axis of the mounting opening.The base can have a mounting section for the sanitary fitting or the fitting body. The mounting section can be at least partially annular and / or tubular. The fitting body can be arranged on the mounting section, in particular with a fitting housing opening. The fitting housing opening can have an inner diameter that corresponds (essentially) to an outer diameter of the mounting section. The sanitary fitting or the fitting body can be movable relative to the device and / or the base between a mounting position and a release position. In particular, the sanitary fitting or the fitting body can be rotatable relative to the device and / or the base between the mounting position and the release position about an axis of rotation, for example at an angle of 20° to 90°, preferably 30° to 50°, and particularly preferably (essentially) 40°.The axis of rotation can be parallel or coaxial with the longitudinal axis. In the fixed position, the sanitary fitting or fitting body is attached to the fixture or base. The sanitary fitting or fitting body can be secured in the fixed position, for example by means of a screw or setscrew, to prevent unwanted movement towards the release position. In the release position, the sanitary fitting or fitting body can be detached from the fixture or base. In particular, the sanitary fitting or fitting body can be pulled off the fixture or base in the release position, for example, parallel to the axis of rotation and / or longitudinal axis.

[0010] The device comprises a shaft connected to the base. The shaft can be formed integrally with the base or be a separate component. The shaft can extend parallel or coaxially to the longitudinal axis. The shaft can have a length of, for example, 70 mm to 200 mm (particularly parallel to the longitudinal axis) and / or an outer diameter of, for example, 20 mm to 60 mm (particularly perpendicular to the longitudinal axis).

[0011] The device comprises a fastening element for attaching the device to the support. The fastening element may be at least partially sleeve-shaped. The fastening element may be an adjusting sleeve or a mounting sleeve. The fastening element may extend parallel or coaxially to the longitudinal axis. The fastening element may have a length of, for example, 100 mm to 300 mm (particularly parallel to the longitudinal axis) and / or an outer diameter of 22 mm to 80 mm (particularly perpendicular to the longitudinal axis). The fastening element may have an inner diameter that corresponds (essentially) to the shaft's outer diameter (particularly perpendicular to the longitudinal axis). The fastening element may have an internal thread by which it can be screwed onto the shaft.The fastening element can be screwed onto the shaft in particular until the fastening element rests against an underside of the carrier.

[0012] The device comprises a fluid valve located in the stem and / or the mounting element. Specifically, the fluid valve is located below the support (after the device is attached to the support). In particular, the fluid valve is not located in the sanitary fitting and / or the fitting body (after the sanitary fitting is attached to the device). This eliminates the need for the fluid valve to require any installation space above the support and / or within the sanitary fitting, thus enabling a slimmer design for the sanitary fitting and / or fitting body. The fluid valve can be part of a quick-change system. The fluid valve can be secured in the stem and / or the mounting element with a locking mechanism. The locking mechanism can be, for example, a clip or a nut.

[0013] The device comprises at least one water channel attached to the liquid valve. In particular, a longitudinal end of the at least one water channel may be attached to the liquid valve. The at least one water channel may be made at least partially of plastic and / or metal. The at least one water channel may be at least partially rigid and / or inflexible. The at least one water channel may be at least partially a pipe and / or not a (flexible) hose. The device may have two (first) water channels, one for cold water and one for hot water.

[0014] For example, the device can have a cold water line for cold water and a hot water line for hot water. The liquid, cold water and / or hot water, can be conveyed from the liquid valve to the sanitary fitting via the at least one water line. The at least one water line extends, in particular from the liquid valve, at least partially through the stem. The at least one water line can extend at least partially through the mounting element and / or the base. The at least one water line can extend towards a base opening of the base, up to the base opening of the base, or through the base opening of the base.A longitudinal end of at least one water channel can be connected to the sanitary fitting, the fitting housing, a cartridge adapter of the sanitary fitting or at least a (second) water channel of the sanitary fitting, for example via a plug connection and / or in particular permanently.

[0015] The liquid valve is adjustable to an open and a closed position via at least one water channel. Specifically, the liquid valve is adjustable to the open and closed positions via at least one water channel when the sanitary fitting or fitting body is moved or rotated relative to the device and / or base between the mounting position and the release position. When the sanitary fitting or fitting body is in the mounting position, the liquid valve is in the open position. When the sanitary fitting or fitting body is in the release position, the liquid valve is in the closed position. In the open position, liquid can flow to the sanitary fitting via at least one water channel.In the closed position, no liquid can flow to the sanitary fitting via the at least one water channel, thus preventing uncontrolled leakage into the environment, particularly if the sanitary fitting is detached from the device. The at least one water channel can be movable and / or rotatable around its axis of rotation by the sanitary fitting or fitting housing if the sanitary fitting or fitting housing is connected to the device. Movement or rotation of the sanitary fitting or fitting housing can be transmitted to the at least one water channel. The liquid valve can be actuated by the movement of the at least one water channel.

[0016] The device allows the sanitary fitting to be replaced with minimal effort.

[0017] The shaft may have a thread. In particular, the shaft may have an external thread. The shaft can be connected or connectable to the base and / or the fastening element via the thread.

[0018] The shaft can be at least partially tubular in shape.

[0019] The fastening element can be at least partially tubular in shape.

[0020] The liquid valve can be rotated into the open and closed positions by means of at least one water guide.

[0021] The liquid valve can have a rigid valve disc and a movable valve disc. The rigid valve disc and / or the movable valve disc can be made at least partially of ceramic. The movable valve disc can be arranged on the rigid valve disc and / or be rotatable, in particular about the axis of rotation. The rigid valve disc and / or the movable valve disc can be arranged in a valve housing of the liquid valve. The rigid valve disc can have at least one first liquid channel and the movable valve disc at least one second liquid channel. For example, the rigid valve disc can have one first liquid channel each for the cold water and the hot water, and the movable valve disc can have one second liquid channel each for the cold water and the hot water.In the open position, the first and second liquid channels can at least partially align, allowing liquid to flow through the liquid valve, i.e., the liquid valve is open. In the closed position, the first and second liquid channels do not align, so no liquid can flow through the liquid valve, i.e., the liquid valve is closed.

[0022] The device may have a connection element for at least one liquid supply line. Liquid, for example from a public water supply network and / or from a hot water source, can be supplied to the device via the at least one liquid supply line. The connection element may have a connection, for example in the form of a socket or a nipple, for the at least one liquid supply line. The connection element may have a cold water connection for a cold water supply line and a hot water connection for a hot water supply line. The connection element may be at least partially located in the shaft and / or the mounting element. The connection element may be manufactured as an injection-molded plastic part. The connection element may be attached to the liquid valve.

[0023] The connection element can be part of the liquid valve. The connection element can be at least partially located in the valve housing and / or attached to the valve housing.

[0024] Following another aspect, a sanitary fitting is proposed which has a fitting body that is attached to a device described here.

[0025] The valve body can be movable relative to the device between a fixed position and a release position, wherein a fluid valve of the device can be adjusted to an open position when the valve body is moved into the fixed position and to a closed position when the valve body is moved into the release position. In particular, the valve body can be rotatable relative to the device between the fixed position and the release position, especially about the axis of rotation, wherein the fluid valve of the device can be rotated into the open position when the valve body is rotated into the fixed position, especially about the axis of rotation, and into the closed position when the valve body is rotated into the release position, especially about the axis of rotation.

[0026] For further details regarding the sanitary fitting, please refer to the full description of the device.

[0027] The invention and its technical context are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention, but that the invention is not limited to this embodiment.

The device 1 comprises a base 4 connected to a shaft 5. The shaft 5 has a thread 17, which is an external thread. The shaft 5 is screwed to the base 4 via the thread 17. The base 4 and the shaft 5 are each tubular and extend along a longitudinal axis 18. The shaft 5 is inserted from above through a mounting opening 19 of the support 3, so that the base 3 sits on a top surface 20 of the support 3 in a desired orientation and the longitudinal axis 18 is aligned coaxially with a longitudinal axis 22 of the mounting opening 19.

[0029] The device 1 comprises a tubular fastening element 6 in the form of an adjusting sleeve extending along the longitudinal axis 18. The fastening element 6 is screwed onto the shaft 5 on a side of the shaft 5 opposite the base 4, extending to a bottom surface 21 of the support 3, thus securing the device 1 to the support 3. A liquid valve 7 is arranged in the fastening element 6. The liquid valve 7 can be inserted into the fastening element 6 from below. The liquid valve 7 has a valve housing 23 in which a rigid valve disc 11 and a movable valve disc 12 are arranged. The rigid valve disc 11 is fixedly arranged in the valve housing 23. The movable valve disc 12 is rotatable about a pivot axis 25 on the rigid valve disc 11 between an open position 10 (shown here) and a closed position.The liquid valve 7 includes a connection element 13 to which a cold water supply line (not shown) and a hot water supply line (also not shown) can be connected. The liquid valve 7 and the connection element 13 are secured in the mounting element 6 by a retainer 24. Two first water channels 8 for the cold water and the hot water are attached to the movable valve disc 12, of which . Fig. 1 only one is visible. The first water channels 8 extend from the movable valve disc 12 through the shaft 5 to a base opening 26 of the base 4.

[0030] Fig. Figure 2 shows the sanitary fitting 2 in a longitudinal section, which is attached to the support 3 by the device 1.

The valve housing 14 is placed with the valve housing opening 28 onto a mounting section 29 of the base 4, so that the two second water channels 9 are connected to longitudinal ends 32 of the two first water channels 8 (liquid-conducting). The valve housing 14 is connected to the mounting section 29 of the base 4 via a bayonet connection and secured to the mounting section 29 with a screw 31 in a mounting position 15. After loosening the screw 31, the valve housing 14 is rotated on the mounting section 29 about a housing pivot axis 30 between the mounting position 15 shown here and a position shown in Fig. The valve body 14 is rotatable in the release position 16 shown in Figure 3. In the fixed position 15, the valve body 14 is attached to the mounting section 29, and in the release position 16, it can be detached or removed from the mounting section 29 parallel to the housing rotation axis 30. The housing rotation axis 30 is coaxial with the rotation axis 25 of the movable valve disc 12 of the liquid valve 7. When the valve body 14 is rotated between the fixed position 15 and the release position 16, the movable valve disc 12 can be rotated about the rotation axis 25 between the open position 10 and the closed position via the water guides 8, 9.

[0031] When the valve body 14 is rotated into the mounting position 15, the movable valve disc 12 is in the open position 10. In the open position 10, the liquid valve 7 is open, allowing cold and hot water to flow via the water channels 8, 9 and the cartridge adapter 27 to a mixing valve 33. The cold and hot water can be mixed by the mixing valve 33 to produce mixed water at the desired temperature. The mixed water can then be discharged via an outlet of the valve body 14 (not shown) to the surrounding area 34 of the sanitary fitting 2.
