Description

[0001] Adapter for connecting a sanitary fitting to an S-connection, sanitary installation with such an adapter, use of an adapter and method for attaching a sanitary fitting

[0002] The present invention relates to an adapter for connecting a sanitary fitting, a sanitary installation with such an adapter, a use of an adapter and a method for fastening a sanitary fitting.

[0003] Sanitary fittings for showers or bathtubs usually have two liquid inlets for cold water and hot water, arranged at a standardized distance from each other. When installing such a sanitary fitting on a wall, the liquid inlets of the sanitary fitting must be connected to a cold water pipe and a hot water pipe, which protrude from the wall at a defined pipe spacing. Since the pipe spacing often does not exactly correspond to the distance between the liquid inlets of the sanitary fitting, an S-connector is screwed into the cold water pipe and the hot water pipe. By adjusting the angle of rotation of the S-connectors in the cold water pipe and / or the hot water pipe, a deviation between the pipe spacing and the distance between the liquid inlets of the sanitary fitting (for example, of up to approx.+ / - 15 mm [millimeters]) can be compensated for, allowing the fluid inlets to be connected to the cold and hot water pipes via the S-connectors and / or allowing the plumbing fixture to be mounted horizontally on the wall. Inaccuracies in the alignment of the S-connectors can be compensated for when attaching the plumbing fixture to the S-connectors using union nuts (e.g., up to approximately + / - 1.5 mm).

[0004] Flush-mounted plumbing fixtures require special S-connectors for wall installation, so any existing S-connectors must be removed when retrofitting flush-mounted plumbing fixtures. This can cause deposits to build up between the S-connectors and the water pipes, which must be laboriously cleaned or removed to prevent damage to the plumbing fixture. Furthermore, the special S-connectors must be resealed to prevent leaks, which increases the installation effort.

[0005] In addition, sleeves are available for installing flush-mounted plumbing fixtures, which are screwed onto the existing S-connectors. However, inaccuracies in the alignment of the S-connectors are not possible with either the sleeves or the flush-mounted plumbing fixtures, as these cannot be attached to the S-connectors using union nuts. Therefore, the existing S-connectors must be frequently realigned and thus rotated. This can, in turn, loosen deposits between the S-connectors and the water pipes, which require extensive cleaning and removal.

[0006] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide an adapter for connecting a sanitary fitting to an S-connection, with which inaccuracies in the alignment of the S-connections can be compensated without rotating the S-connections. In addition, a sanitary installation is to be provided with an adapter that can compensate for inaccuracies in the alignment of the S-connections without rotating the S-connections. Furthermore, the use of an adapter is to be specified by which inaccuracies in the alignment of the S-connections can be compensated without rotating the S-connections. In addition, a method for attaching a sanitary fitting to an S-connection is to be proposed.

[0007] These objects are achieved with an adapter according to the features of independent claim 1. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention. Furthermore, the features listed in the claims are further specified and explained in the description, with further preferred embodiments of the invention being presented. This is achieved by an adapter for connecting a sanitary fitting to an S-connection, which adapter comprises at least the following: a sleeve element, at least having a first end face, a second end face, and a first internal thread; and an eccentric sleeve,

[0008] The sleeve element has a receptacle on the second end face in which the eccentric sleeve is rotatably arranged, so that a connecting piece of the eccentric sleeve, which can be arranged in a connection receptacle of the sanitary fitting, can be arranged eccentrically relative to the sleeve element by rotating the eccentric sleeve relative to the sleeve element. The sleeve element with the eccentric sleeve can be pushed onto the S-connector along an axial direction via the first end face (of the sleeve element) and can be connected to a first external thread of the S-connector (the first external thread is therefore present on an outer peripheral surface of the S-connector) via the first internal thread (the first internal thread is therefore present on an inner peripheral surface of the sleeve element).

[0009] The S-connector is used to connect a water pipe and a sanitary fitting. The water pipe can, for example, be a warm water pipe for hot water or a cold water pipe for cold water. The sanitary fitting can, in particular, provide mixed water to a shower, bathtub, washbasin and / or kitchen sink as needed. The sanitary fitting can, for example, be a flush-mounted sanitary fitting, a shower fitting, a bathroom fitting and / or a thermostatic mixer fitting. The sanitary fitting can have a mixing valve, a thermostatic mixing valve, a mixing cartridge or a thermostatic mixer cartridge through which the cold water with a cold water temperature and the hot water with a hot water temperature can be mixed to form mixed water with a desired mixed water temperature.The hot water temperature is in particular a maximum of 90°C, preferably 25°C to 90°C, particularly preferably 55°C to 65°C and / or the cold water temperature is in particular a maximum of 25°C (Celsius), preferably 1°C to 25°C, particularly preferably 5°C to 20°C. The sanitary fitting can have a fitting housing and / or can be fastened to a support, such as a wall. The sanitary fitting or the fitting housing can have a first liquid inlet for the hot water and / or a second liquid inlet (hereinafter the two liquid inlets are also referred to as the connection receptacle of the sanitary fitting) for the cold water. The first liquid inlet and the second liquid inlet can, for example, have an inlet distance of, for example, 120 mm to 180 mm, preferably (essentially) 150 mm.The first fluid inlet can be connected to the hot water pipe via a (first) S-connection, and / or the second fluid inlet can be connected to the cold water pipe via a (second) S-connection. The sanitary fitting can be supplied with hot water, in particular, via the hot water pipe, and / or cold water, in particular, via the cold water pipe, from a public water supply network and / or a water heater. Furthermore, the hot water pipe can be connected to a hot water source for the hot water, and / or the cold water pipe can be connected to a cold water source for the cold water.

[0010] The S-connector can have a second external thread for connecting to the (wall-side) water pipe. The S-connector can be screwed into the water pipe via the second external thread. For this purpose, the water pipe can have a corresponding internal thread. The second external thread is formed in particular in the area of ​​a second connection of the S-connector. Furthermore, the S-connector has the first external thread.

[0011] The first external thread is formed in particular in the region of a first connection of the S-connector. The S-connector comprises, in particular, a fluid channel extending from the second connection to the first connection. Thus, the water can be guided from the second connection to the first connection via the fluid channel.

[0012] The liquid channel can, for example, have a length of 50 mm to 200 mm, preferably 50 mm is 100 mm. In particular, the water can enter the second connection and exit from the first connection. The S-connection is, in particular, tubular in design between the second connection and the first connection or between the second external thread and the first external thread. In addition, the S-connection can have a diameter of a maximum of 25 mm, preferably a maximum of 3 / 4" (inch), in particular over its entire length. Furthermore, the S-connection can have a wall thickness of 1 mm to 10 mm, preferably 1 mm to 5 mm, in the region of the second external thread and / or first external thread or in the region of the second connection or first connection. Furthermore, the S-connection can be made at least partially of metal, such as brass, and / or have a coated or chrome-plated surface. The second external thread orthe second connection can have a second connection longitudinal axis and the first external thread or the first connection can have a first connection longitudinal axis. The second connection longitudinal axis is in particular a center axis of the second external thread or the second connection and / or the first connection longitudinal axis is in particular a center axis of the first external thread or the first connection. The second external thread extends in particular around the second connection longitudinal axis and / or the first external thread in particular around the first connection longitudinal axis. The second connection longitudinal axis and first connection longitudinal axis also have in particular a straight course. The second external thread and the first external thread or the second connection and the first connection can be connected to one another, for example, via a transverse channel which runs at least partially transversely or at an angle to the first longitudinal axis and / or second longitudinal axis.The second external thread can have, in particular, a second length of 10 mm (millimeters) to 50 mm, preferably 10 mm to 30 mm, parallel to the second connection longitudinal axis. Furthermore, the first external thread can have, in particular, a first length of 10 mm to 50 mm, preferably 10 mm to 30 mm, parallel to the first connection longitudinal axis. In addition, the first external thread can extend parallel to the first connection longitudinal axis over at least 75%, preferably over at least 95%, of a first connection length of the first connection. Furthermore, the second external thread can extend parallel to the second connection longitudinal axis over at least 75%, preferably over at least 95%, of a second connection length of the second connection. The first external thread and the second external thread orThe first connection and the second connection have a longitudinal spacing of, for example, 10 mm to 100 mm, preferably 30 mm to 70 mm, in particular parallel to the first connection longitudinal axis and the second connection longitudinal axis. The first connection longitudinal axis and the second connection longitudinal axis run parallel and at a spacing from one another. The spacing can be, for example, 1 mm to 100 mm, preferably 5 mm to 50 mm. As a result, the S-connection has, in particular, an S-shaped profile. An S-shaped profile is characterized in particular by straight but radially offset connections, between which a bend or deflection is provided.

[0013] The sanitary fitting can be connected to the S-connector using the adapter. In particular, the sanitary fitting can be connected to the first S-connector using a first adapter and to the second S-connector using a second adapter. The first adapter and the second adapter can be identical.

[0014] The adapter has a sleeve element for fastening to the S-connector. The sleeve element can be fastened in particular to the first connection or the first external thread of the S-connector. The S-connector can be secured against twisting relative to the water pipe when the sleeve element is fastened. The sleeve element can be designed as a sleeve or screw sleeve (with the first internal thread). The sleeve element can consist at least partially of plastic and / or metal, such as brass. The sleeve element can have an outer circumferential surface, which can in particular be partially designed as a nut (which can therefore be grasped, for example, by an open-end wrench and rotated thereby). The outer circumferential surface of the sleeve element can, for example, have a (first) outer diameter of, for example, 20 mm to 40 mm.

[0015] The sleeve element extends in particular along the axial direction from a first end face to a second end face. The sleeve element can be pushed along an axial direction via the first end face onto the S-connector and can be connected to a first external thread of the S-connector via the first internal thread. The sleeve element has a receptacle on the second end face. The end faces and the first internal thread are arranged in particular concentrically to one another. The eccentric sleeve is a separate component that is rotatably arranged in the receptacle. The eccentric sleeve can be pushed into the sleeve element in particular via the first end face and can thus be arranged in the receptacle. The eccentric sleeve extends from the receptacle with a (sleeve-like) connecting piece along the axial direction. The connecting piece can have a seal (e.g.a sealing ring) so that the connecting piece forms a fluid-tight connection with the connection receptacle of the sanitary fitting. The connecting piece is arranged eccentrically to the part of the eccentric sleeve that is located in the receptacle. By rotating the eccentric sleeve relative to the sleeve element, the connecting piece can be arranged eccentrically relative to the end faces and the first internal thread of the sleeve element.

[0016] The sanitary fitting or the fluid inlets / connection receptacles of the sanitary fitting can be plugged onto the adapter or the connection piece of the eccentric sleeve so that the sanitary fitting is flush with a support or the wall.

[0017] In particular, the eccentric sleeve has a disk-shaped, circular connecting element with a first central axis extending along the axial direction for rotatable arrangement in the receptacle. In particular, the sleeve element has a stop for the connecting element on the second end face, so that the connecting element can be supported against the stop with respect to the axial direction.

[0018] In particular, the adapter has a seal that can be arranged in the receptacle of the sleeve element and along the axial direction between the connecting element and the S-connector. In particular, the seal is designed as a flat seal with a sieve. The sieve can prevent, for example, deposits from getting into the sanitary fitting. In particular, the seal is clamped between the front end of the S-connector and the connecting element by screwing the sleeve element onto the S-connector when the connecting element is supported on the stop formed on the receptacle. In particular, the connecting piece extends in a sleeve-like manner along an axial direction around a second central axis, wherein the first central axis (of the sleeve element) and the second central axis (of the connecting piece) run parallel but offset from one another.

[0019] The eccentric sleeve of the adapter is in particular eccentric and (in particular relative to the sleeve element, about a first central axis of the sleeve element and / or indefinitely) rotatable on the sleeve element, so that inaccuracies in the alignment of the S-connections can be compensated for without rotating the S-connections and / or so that in particular an offset between the S-connection and a connection receptacle of the sanitary fitting can be compensated for. The eccentric sleeve can be made at least partially of plastic and / or metal, such as brass. The receptacle of the sleeve element serves in particular as a pivot bearing for the eccentric sleeve. The sleeve element and the eccentric sleeve can be flowed through, in particular, by water when the sanitary fitting is in use.

[0020] The eccentric sleeve can have an eccentricity relative to the sleeve element, which can be, for example, up to 10 mm, preferably up to 5 mm, particularly preferably (essentially) 2 mm.

[0021] In particular, the sleeve element (according to a first embodiment of the adapter) has a second external thread (on an outer circumferential surface of the sleeve element). The adapter has, in particular, a nut that can be arranged on the second external thread and a locking plate that interacts with the sanitary fitting. The (disk-shaped) locking plate can be arranged, in particular, along the axial direction between the nut and a connection plate of the sanitary fitting, so that by rotating the nut relative to the sleeve element, the locking plate can be displaced together with the sanitary fitting or at least with the connection plate along the axial direction towards the S-connection (or the wall). The sanitary fitting (or the part of the sanitary fitting that does not comprise the connection plate) can, for example, be connected or connectable to the connection plate via at least one clamping screw.In particular, the adapter (according to a second embodiment of the adapter) has a mounting plate that is supported on the first end face of the sleeve element relative to the axial direction, wherein the mounting plate has at least one threaded receptacle for a clamping screw. The sanitary fitting can be fastened to the mounting plate via the at least one clamping screw and can be displaced along the axial direction toward the S-connection (or the wall).

[0022] By rotating the eccentric sleeve relative to the sleeve element, inaccuracies in the alignment of the S-connectors can be compensated for without rotating the S-connectors, for example, during renovation and / or retrofitting of the plumbing fixture. In particular, by turning the nut (first design of the adapter) or by screwing the clamping screw into the threaded receptacle (second design of the adapter), especially on the first adapter and the second adapter, the position of the plumbing fixture relative to the wall can be adjusted, allowing, for example, the plumbing fixture to be arranged flush with the wall.

[0023] Following a further aspect, a sanitary installation is also proposed which has at least the following:

[0024] - at least one S-connection;

[0025] - at least one adapter as proposed here, which is attached to the at least one S-connector; and

[0026] - a sanitary fitting attached to the at least one adapter.

[0027] For further details on the plumbing installation, please refer to the adapter description.

[0028] Following yet another aspect, the use of an adapter proposed here for connecting a plumbing fixture to an S-connector is also proposed. For further details on the use, please also refer to the full description of the adapter.

[0029] A method for attaching a sanitary fitting to an S-connection extending from a wall using an adapter described here is also proposed. The method comprises at least the following steps: a) arranging the eccentric sleeve (and any seal present) in the receptacle of the sleeve element; b) sliding the sleeve element with the eccentric sleeve (and the seal) onto the S-connection; c) connecting the sleeve element to the S-connection via the first internal thread of the sleeve element and the first external thread of the S-connection (wherein the seal is arranged along the axial direction between a front end of the S-connection and the eccentric sleeve); d) aligning the eccentric sleeve with the connection receptacle of the sanitary fitting (e.g. using a template or via the sanitary fitting); e) tightening the sleeve element and thus fixing a position of the eccentric sleeve relative to the S-connection (and any seal).Clamp the seal between the front end of the S-connector and the eccentric sleeve); f) Slide the sanitary fitting onto the adapter so that the eccentric sleeve (or the connection piece) is positioned in a connection receptacle of the sanitary fitting.

[0030] The above (non-exhaustive) division of the process steps into a) to f) is primarily intended to serve as a distinction and does not enforce any order and / or dependency. Individual or multiple steps can be repeated multiple times (e.g. steps c) to e) or only steps d) and e)). Steps a) to f) are preferably carried out in the order listed, although some steps can also be carried out at least partially simultaneously (e.g. steps c) to e)). The steps of the process are particularly carried out manually. If necessary, step a) can already be carried out as component assembly independently of the other steps of the process, so that the process for attaching the sanitary fitting to the installation site begins with step b).

[0031] In particular, the sleeve element has a second external thread, wherein the adapter (designed according to the first embodiment) has a nut that can be arranged on the second external thread and a locking plate that interacts with the sanitary fitting. The locking plate is arranged on the adapter at least immediately after step e) (if necessary also earlier, i.e. during one of steps a) to e)), wherein the locking plate is arranged along the axial direction between the nut and the wall. During step f), a connecting plate of the sanitary fitting is pushed over the locking plate along the axial direction, the locking plate is then rotated (e.g. by approximately 90 degrees) and thus a positive connection with the connecting plate is formed with respect to the axial direction. By rotating the nut relative to the sleeve element, the locking plate is locked together with the sanitary fitting (orAt least the connecting plate) is displaced along the axial direction toward the wall. In particular, each adapter has its own locking plate. In particular, even with two adapters, only one common connecting plate is provided.

[0032] In particular, the remaining part of the sanitary fitting (without the connection plate) can be or will be connected to the connection plate via at least one clamping screw.

[0033] In particular, the adapter (designed according to the second embodiment) has a mounting plate, which in step b) is pushed onto the S-connector together with the sleeve element and the eccentric sleeve. The mounting plate is supported on the first end face of the sleeve element opposite the axial direction. The mounting plate has at least one threaded receptacle for a clamping screw. During step f), the sanitary fitting is attached to the mounting plate via the clamping screw and is displaced along the axial direction toward the wall (by further screwing the clamping screw into the threaded receptacle). In particular, each adapter has its own mounting plate.

[0034] The use of indefinite articles ("a", "an", "an" and "another"), particularly in the patent claims and the description reproducing them, is to be understood as such and not as a numeral. Terms or components introduced accordingly are therefore to be understood as being present at least once and, in particular, can also be present multiple times.

[0035] As a precaution, it should be noted that the numerals used here ("first", "second", ...) primarily serve (only) to distinguish between several similar objects, quantities, or processes, and therefore do not necessarily prescribe any interdependence and / or sequence of these objects, quantities, or processes. Should a dependence and / or sequence be necessary, this is explicitly stated here or will be obvious to the person skilled in the art upon studying the specifically described embodiment. To the extent that a component can occur multiple times ("at least one"), the description of one of these components can apply equally to all or part of the majority of these components, but this is not mandatory.

[0036] 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 of the invention, but are not limited thereto. Identical components in the figures are provided with the same reference numerals. They show, by way of example and schematically:

[0042] Fig. 1 shows a cross-sectional view of a sanitary installation 27 according to a first embodiment. Fig. 2 shows a part of the sanitary installation 27 according to Fig. 1 in a front view. Fig. 3 shows the sanitary installation 27 according to Fig. 1 in a perspective view. Figs. 1 to 3 are described together below.

[0043] The sanitary installation 27 comprises two S-connections 4, 5, two adapters 1, 2 (constructed according to the first embodiment), and a sanitary fitting 3. Each adapter 1, 2 is arranged on an S-connection 4, 5. The sanitary fitting 3 is attached to the S-connections 4, 5 via the two adapters 1, 2.

[0044] Each adapter 1, 2 comprises a sleeve element 6, having at least a first end face 7, a second end face 8 and a first internal thread 9, as well as an eccentric sleeve 10. The sleeve element 6 has a receptacle 11 on the second end face 8, in which the eccentric sleeve 10 is rotatably arranged, so that a connecting piece 12 of the eccentric sleeve 10, which can be or is arranged in a connecting receptacle 13 of the sanitary fitting 3, can be arranged eccentrically relative to the sleeve element 6 by rotating the eccentric sleeve 10 relative to the sleeve element 6. The sleeve element 6 with the eccentric sleeve 10 can be pushed onto the S-connector 4, 5 along an axial direction 14 via the first end face 7 (of the sleeve element 6) and can be connected or connected via the first internal thread 9 to a first external thread 15 of the S-connector 4, 5. The sanitary fitting 3 can be fastened or is fastened to a support, such as a wall 28.The sanitary fitting 3 has a first liquid inlet for the hot water and a second liquid inlet (these two liquid inlets are referred to as connection receptacles 13 of the sanitary fitting 3) for the cold water. The first liquid inlet and the second liquid inlet can, for example, have an inlet distance of 120 mm to 180 mm, preferably (essentially) 150 mm. The first liquid inlet is connectable or connected to the hot water line via the first S-connection 4, and the second liquid inlet is connected to the cold water line via the second S-connection 5.

[0045] The S-connector 4, 5 has a second external thread 20 (here located in the wall 28) for connection to the (wall-side) water pipe. The S-connector 4, 5 can be screwed into the water pipe via the second external thread 20. Furthermore, the S-connector 4, 5 has the first external thread 15.

[0046] The first external thread 15 is formed in the region of a first connection of the S-connector 4, 5. The S-connector 4, 5 comprises a fluid channel extending from the second connection (in the wall 28 or oriented toward the water line) to the first connection (oriented toward the adapter 1, 2). Thus, the water can be guided via the fluid channel from the second connection to the first connection. Each S-connector 4, 5 has an S-shaped profile.

[0047] The sanitary fitting 3 can be connected to the S-connectors 4 and 5 using the adapters 1 and 2. The first adapter 1 and the second adapter 2 are identical.

[0048] The adapter 1, 2 has a sleeve element 6 for fastening to the S-connector 4, 5. The sleeve element 6 is fastened to the first connection or the first external thread 15 of the S-connector 4, 5. The S-connector 4, 5 is secured against rotation relative to the water pipe when the sleeve element 6 is fastened. The sleeve element 6 is designed as a sleeve or screw sleeve (with the first internal thread 9). The sleeve element 6 has an outer circumferential surface, which is partially designed as a nut 21 (in Fig. 1 above the second external thread 20 or the nut 21) (which can therefore be grasped, for example, by an open-end wrench and rotated thereon).

[0049] The sleeve element 6 extends along the axial direction 14 from a first end face 7 to a second end face 8. The sleeve element 6 can be pushed along an axial direction 14 over the first end face 7 onto the S-connector 4, 5 and can be connected via the first internal thread 9 to a first external thread 15 of the S-connector 4, 5. On the second end face 8, the sleeve element 6 has a receptacle 11. The end faces 7, 8 and the first internal thread 9 are arranged concentrically to one another.

[0050] The eccentric sleeve 10 is a separate component from the sleeve element 6 and is rotatably arranged in the receptacle 11. The eccentric sleeve 10 can be inserted into the sleeve element 6 via the first end face 7 and thus arranged in the receptacle 11. The eccentric sleeve 10 extends from the receptacle 11 with a (sleeve-like) connecting piece 12 along the axial direction 14. The connecting piece 12 has a seal (a sealing ring) on ​​an outer circumferential surface, so that the connecting piece 12 forms a fluid-tight connection with the connection receptacle 13 of the sanitary fitting 3. The connecting piece 12 is arranged eccentrically to the part of the eccentric sleeve 10 that is arranged in the receptacle 11. By rotating the eccentric sleeve 10 relative to the sleeve element 6, the connecting piece 12 can be arranged eccentrically relative to the end faces 7, 8 and the first internal thread 9 of the sleeve element 6.

[0051] The sanitary fitting 3 or the liquid inlets / connection receptacles 13 of the sanitary fitting 3 can be plugged onto the adapters 1, 2 or the connection piece 12 of the eccentric sleeves 10, so that the sanitary fitting 3 is flush with a support or the wall 28.

[0052] For rotatable arrangement in the receptacle 11, the eccentric sleeve 10 has a disc-shaped, circular connecting element 16 with a first central axis 17 extending along the axial direction 14. The sleeve element 6 has a stop 29 for the connecting element 16 on the second end face 8, so that the connecting element 16 can be supported on the stop 29 with respect to the axial direction 14.

[0053] The adapter 1, 2 has a seal 18 arranged in the receptacle 11 of the sleeve element 6 and along the axial direction 14 between the connecting element 16 and the S-connector 4, 5. The seal 18 is designed as a flat seal with a sieve. The sieve can prevent, for example, deposits from entering the sanitary fitting 3. The seal 18 is clamped between the front end of the S-connector 4, 5 and the connecting element 16 by screwing the sleeve element 6 onto the S-connector 4, 5, when the connecting element 16 is supported on the stop 29 formed on the receptacle 11.

[0054] The connecting piece 12 extends along the axial direction 14 in a sleeve-like manner around a second central axis 19, wherein the first central axis 17 (of the sleeve element 6) and the second central axis 19 (of the connecting piece 12) run parallel but offset from one another.

[0055] The eccentric sleeve 10 of the adapter 1, 2 is eccentric and attached to the sleeve element 6 so as to be infinitely rotatable about a first central axis 17 of the sleeve element 6, so that inaccuracies in the alignment of the S-connectors 4, 5 can be compensated for without rotating the S-connectors 4, 5 and / or so that, in particular, an offset between the S-connector 4, 5 and a connection receptacle 13 of the sanitary fitting 3 can be compensated for. The receptacle 11 of the sleeve element 6 serves as a pivot bearing for the eccentric sleeve 10. Water can flow through the sleeve element 6 and the eccentric sleeve 10 when the sanitary fitting 3 is in use.

[0056] The eccentric sleeve 10 can have an eccentricity (i.e., the offset between the first central axis 17 and the second central axis 19) relative to the sleeve element 6, which can be, for example, up to 10 mm. The sleeve element 6 according to the first embodiment of the adapter 1, 2 has a second external thread 20 on an outer circumferential surface of the sleeve element 6. The adapter 1, 2 has a nut 21 arranged on the second external thread 20 and a locking plate 22 that interacts with the sanitary fitting 3. The disc-shaped locking plate 22 is arranged along the axial direction 14 between the nut 21 and a connecting plate 23 of the sanitary fitting 3, so that by rotating the nut 21 relative to the sleeve element 6, the locking plate 22 can be displaced together with the sanitary fitting 3 or at least with the connecting plate 23 along the axial direction 14 towards the S-connection 4, 5 (or the wall 28). The sanitary fitting 3 (orThe connecting part (i.e., the part of the sanitary fitting 3 which does not comprise the connecting plate 23) can be connected to the connecting plate 23 via at least one clamping screw 26 which is screwed into a threaded receptacle 25 of the connecting plate 23 (the clamping screws 26 are indicated in Fig. 3).

[0057] By rotating the eccentric sleeve 10 relative to the sleeve element 6, inaccuracies in the alignment of the S-connections 4, 5 with regard to a distance 30 can be compensated for without rotating the S-connections 4, 5, for example during renovation and / or retrofitting of the sanitary fitting 3. By rotating the nut 21 on the first adapter 1 and on the second adapter 2, a position of the sanitary fitting 3 relative to the wall 28 can be adjusted, so that, for example, the sanitary fitting 3 can also be arranged flush with the wall 28.

[0058] In the method for fastening the sanitary fitting 3 to the S-connections 4, 5 extending from a wall 28 with the adapters 1, 2, according to step a), the eccentric sleeve 6 and the seal 18 are arranged in the receptacle 11 of the sleeve element 6. According to step b), the sleeve element 6 with the eccentric sleeve 10 and the seal 18 is pushed onto the S-connection 4, 5. According to step c), the sleeve element 6 is connected to the S-connection 4, 5 via the first internal thread 9 of the sleeve element 6 and the first external thread 15 of the S-connection 4, 5, wherein the seal 18 is arranged along the axial direction 14 between a front end of the S-connection 4, 5 and the eccentric sleeve 10. According to step d), the respective eccentric sleeve 10 is aligned with the connection receptacles 13 of the sanitary fitting 3, which are arranged at a distance 30 from each other (see Fig. 2).The second center axes 19 of the connecting pieces 12 are then arranged concentrically with the connection receptacles 13. According to step e), the sleeve element 6 is tightened, thus fixing the position of the eccentric sleeve 10 relative to the S-connector 4, 5, and clamping the seal 18 between the front end of the S-connector 4, 5 and the eccentric sleeve 10. According to step f), the sanitary fitting 3 is pushed onto the adapter 1, 2, so that the eccentric sleeve 10 or the connecting piece 12 is arranged in the respective connection receptacle 13 of the sanitary fitting 3.

[0059] The locking plate 22 is arranged on the adapter 1, 2 at least immediately after step e) (possibly also earlier, i.e. during one of steps a) to e)), wherein the locking plate 22 is arranged along the axial direction 14 between the nut 21 and the wall 28. During step f), a connection plate 23 of the sanitary fitting 3 is pushed over the locking plate 22 along the axial direction 14, the locking plate 22 is then rotated (e.g., by approximately 90 degrees) and thus a positive connection with the connection plate 23 is formed with respect to the axial direction 14 (see Figs. 2 and 3). By rotating the nut 21 relative to the sleeve element 6, the locking plate 22 is displaced together with the sanitary fitting 3 or at least the connection plate 23 along the axial direction 14 towards the wall 28. Each adapter 1, 2 has its own locking plate 22.For two adapters 1, 2, only one common connection plate 23 is provided.

[0060] In particular, the remaining part of the sanitary fitting 3 (without connection plate 23) can be or become connected to the connection plate 23 via at least one clamping screw 26 (see Fig. 3).

[0061] Fig. 4 shows a cross-sectional view of part of a sanitary installation 27 according to a second embodiment. Fig. 5 shows the part of the sanitary installation 27 according to Fig. 4 in a front view. Fig. 6 shows the sanitary installation 27 according to Figs. 4 and 5 in a perspective view. Figs. 4 to 6 are described together below. Reference is made to the explanations for Figs. 1 to 3.

[0062] The plumbing installation 27 comprises two S-connections 4, 5, two adapters 1, 2 (constructed according to the second embodiment), and a plumbing fitting 3. Each adapter 1, 2 is arranged on an S-connection 4, 5. The plumbing fitting 3 is attached to the S-connections 4, 5 via the two adapters 1, 2.

[0063] Each adapter 1, 2 comprises a sleeve element 6, having at least a first end face 7, a second end face 8 and a first internal thread 9, as well as an eccentric sleeve 10. The sleeve element 6 has a receptacle 11 on the second end face 8, in which the eccentric sleeve 6 is rotatably arranged, so that a connecting piece 12 of the eccentric sleeve 6, which can be or is arranged in a connecting receptacle 13 of the sanitary fitting 3, can be arranged eccentrically relative to the sleeve element 6 by rotating the eccentric sleeve 10 relative to the sleeve element 6. The sleeve element 6 with the eccentric sleeve 10 can be pushed along an axial direction 14 via the first end face 7 (of the sleeve element 6) onto the S-connection 4, 5 and can be connected or connected via the first internal thread 9 to a first external thread 15 of the S-connection 4, 5.

[0064] The sanitary fitting 3 can be connected to the S-connectors 4 and 5 using the adapters 1 and 2. The first adapter 1 and the second adapter 2 are identical.

[0065] The adapter 1, 2 has a sleeve element 6 for attachment to the S-connector 4, 5. The sleeve element 6 is attached to the first connection or the first external thread 15 of the S-connector 4, 5. The S-connector 4, 5 is secured against rotation relative to the water pipe when the sleeve element 6 is attached. The sleeve element 6 is designed as a sleeve or screw sleeve (with the first internal thread 9). The sleeve element 6 has an outer circumferential surface designed as a nut 21 (which can therefore be gripped, for example, by an open-end wrench and rotated thereon). The sleeve element 6 extends along the axial direction 14 from a first end face 7 to a second end face 8. The sleeve element 6 can be pushed along an axial direction 14 via the first end face 7 onto the S-connection 4, 5 and can be connected via the first internal thread 9 to a first external thread 15 of the S-connection 4, 5.On the second end face 8, the sleeve element 6 has a receptacle 11. The end faces 7, 8 and the first internal thread 9 are arranged concentrically to each other.

[0066] The eccentric sleeve 10 is a separate component from the sleeve element 6 and is rotatably arranged in the receptacle 11. The eccentric sleeve 10 can be inserted into the sleeve element 6 via the first end face 7 and thus arranged in the receptacle 11. The eccentric sleeve 6 extends from the receptacle 11 with a (sleeve-like) connecting piece 12 along the axial direction 14. The connecting piece 12 has a seal (a sealing ring) on ​​an outer circumferential surface, so that the connecting piece 12 forms a fluid-tight connection with the connection receptacle 13 of the sanitary fitting 3. The connecting piece 12 is arranged eccentrically to the part of the eccentric sleeve 10 that is arranged in the receptacle 11. By rotating the eccentric sleeve 10 relative to the sleeve element 6, the connecting piece 12 can be arranged eccentrically relative to the end faces 7, 8 and the first internal thread 9 of the sleeve element 6.

[0067] For rotatable arrangement in the receptacle 11, the eccentric sleeve 10 has a disc-shaped, circular connecting element 16 with a first central axis 17 extending along the axial direction 14. The sleeve element 6 has a stop 29 for the connecting element 16 on the second end face 8, so that the connecting element 16 can be supported on the stop 29 with respect to the axial direction 14.

[0068] The adapter 1, 2 has a seal 18 arranged in the receptacle 11 of the sleeve element 6 and along the axial direction 14 between the connecting element 16 and the S-connector 4, 5. The seal 18 is designed as a flat seal with a sieve. The sieve can prevent, for example, deposits from entering the sanitary fitting 3. The seal 18 is clamped between the front end of the S-connector 4, 5 and the connecting element 16 by screwing the sleeve element 6 onto the S-connector 4, 5, when the connecting element 16 is supported on the stop 29 formed on the receptacle 11.

[0069] The connecting piece 12 extends along the axial direction 14 in a sleeve-like manner around a second central axis 19, wherein the first central axis 17 (of the sleeve element 6) and the second central axis 19 (of the connecting piece 12) run parallel but offset from one another.

[0070] The eccentric sleeve 10 of the adapter 1, 2 is eccentric and attached to the sleeve element 6 so as to be infinitely rotatable about a first central axis 17 of the sleeve element 6, so that inaccuracies in the alignment of the S-connectors 4, 5 can be compensated for without rotating the S-connectors 4, 5 and / or so that, in particular, an offset between the S-connector 4, 5 and a connection receptacle 13 of the sanitary fitting 3 can be compensated for. The receptacle 11 of the sleeve element 6 serves as a pivot bearing for the eccentric sleeve 10. Water can flow through the sleeve element 6 and the eccentric sleeve 10 when the sanitary fitting 3 is in use.

[0071] The eccentric sleeve 10 can have an eccentricity (i.e. the offset between the first central axis 17 and the second central axis 19) relative to the sleeve element 6, which can be up to 10 mm, for example.

[0072] Each adapter 1, 2 according to the second embodiment variant has a mounting plate 24, which is supported on the first end face 7 of the sleeve element 6 opposite the axial direction 14, wherein the mounting plate 24 has two threaded receptacles 25 for clamping screws 26. The sanitary fitting 3 can be fastened to the mounting plate 24 via the clamping screws 26 and can be displaced along the axial direction 14 toward the S-connection 4, 5 (or the wall 28). By rotating the eccentric sleeve 10 relative to the sleeve element 6, inaccuracies in the alignment of the S-connections 4, 5 can be compensated for without rotating the S-connections 4, 5, for example during renovation and / or retrofitting of the sanitary fitting 3. By screwing the clamping screws 26 into the threaded receptacles 25 on the first adapter 1 and on the second adapter 2, the position of the sanitary fitting 3 relative to the wall 28 can be adjusted, so that e.g.the sanitary fitting 3 can also be arranged flush with the wall 28.

[0073] Steps a) to f) are carried out in the same way as in the first design variant (see explanations for Figs. 1 to 3).

[0074] In the second embodiment, the fastening plates 24 are pushed onto the S-connector 4, 5 in step b) together with the sleeve element 6 and the eccentric sleeve 10. The fastening plates 24 are supported on the first end face 7 of the sleeve element 6 opposite the axial direction 14. The fastening plates 24 each have two threaded receptacles 25 for clamping screws 26. During step f), the sanitary fitting 3 is fastened to the fastening plate 24 via the clamping screws 26 and is successively moved along the axial direction 14 towards the wall 28 by further screwing the clamping screws 26 into the threaded receptacles 25. Each adapter 1, 2 has its own fastening plate 24.
