Description

[0001] Water fitting comprising a housing with at least one water connection and with an outflow opening

[0002] The invention relates to a water fitting comprising a housing with at least one water connection, preferably a cold and a hot water connection, and with an outflow opening, wherein the water fitting further comprises a cartridge arranged in the housing, which has a tiltable, preferably also pivotable, adjusting element in the region of its upper end, and preferably protruding from the upper side of the housing, and a lever head connected to the adjusting element, which can be tilted between its shut-off position, in which the water fitting is closed, and a flow position, in which water flows out of the outflow opening.

[0003] A water faucet consists of a housing with a cartridge inside. The housing is attached to a wall or a sink, for example. The housing has a spout with an outlet opening. Additionally, a lever head is provided that can be manually tilted at least about a horizontal axis to regulate the amount of water flowing out. To change the amount of water, the lever head is pivoted about the horizontal axis and moved into different positions. If the lever head is tilted as far downwards as possible about the horizontal axis, the water flow stops. The cartridge is a unit located inside the housing that is used to adjust the amount of water and, if necessary, to mix cold and hot water. The water faucet can be designed as a single-lever mixer.A single-lever mixer also allows you to adjust the desired water temperature. If the faucet is designed as a single-lever mixer, it has both a cold and a hot water connection. When the lever head is pivoted left or right around a vertical axis, more cold or hot water is allowed to pass through the cartridge, thereby adjusting the overall temperature of the mixed water. A single-lever mixer is often used in kitchens and bathrooms to mix hot and cold water, delivering more or less water per unit of time depending on the infinitely variable position of the lever head.

[0004] In daily practice, it's common to see a lever head tilted too far into its flow position. This results in more water flowing out than is actually needed. This is especially noticeable with children. Children regularly set high flow rates, resulting in increased water consumption.

[0005] The object of the invention is to avoid the aforementioned disadvantages and to provide a water fitting by means of which water consumption can be limited.

[0006] This object is achieved in that, in order to reduce the maximum amount of water flowing out via the outflow opening in the flow position, a tilting path limiting device is provided which is preferably arranged in a detachable manner and has at least one stop surface, wherein in the maximum possible flow position the tilting path limiting device strikes the housing either directly or indirectly with at least one stop surface and in this way the maximum possible tilting path of the lever head from its shut-off position into its flow position is reduced or strikes the lever head directly or indirectly and in this way the maximum possible tilting path of the lever head from its shut-off position into its flow position is reduced.

[0007] The tilt limiting device can be attached to the lever head. If the tilt limiting device's stop surface directly abuts the housing, the stop surface is in direct contact with the housing. However, it is also entirely possible for the housing to have a damping layer, for example, in the area where it interacts with the stop surface in the maximum flow position. In this case, the tilt limiting device's stop surface indirectly abuts the housing in the flow position.

[0008] Alternatively, the tilt limiting device can be attached to the housing. If the tilt limiting device's stop surface directly abuts the lever head, the stop surface is in direct contact with the lever head. However, it is also entirely possible for the lever head to have a damping layer, for example, in the area where it interacts with the stop surface in the maximum yield position. In this case, the tilt limiting device's stop surface indirectly abuts the lever head in the yield position.

[0009] The water flow is adjusted by tilting the adjustment element around a horizontal axis. By pivoting the adjustment element around the vertical axis, the proportion of cold and hot water, and thus the temperature of the water flowing through the outlet, can be adjusted.

[0010] The tilt limiting device limits the tilting travel of the lever head. In this way, the maximum escaping water flow is reduced by the tilt limiting device, thus lowering water consumption and therefore costs. On the one hand, this affects the cost of the water saved. On the other hand, it also reduces the energy costs for heating the water. The tilt limiting device can be factory-installed on a water fixture. However, the tilt limiting device is also suitable for retrofitting to a water fixture. Installation is simple and can be carried out by anyone without prior experience. The tilt limiting device is mounted either on the back of the lever head or on the back of the housing and limits the tilting travel of the lever head without further compromising functionality or aesthetics.

[0011] Advantageously, the lever head can have an edge region pointing in the direction of the housing, and the tilting travel limiting device can have a receiving groove, preferably U-shaped, open in the direction of the edge region to be received, for receiving the edge region of the lever head, which consists of two legs connected to one another by a web and arranged at a distance from one another. In this embodiment, the two legs, together with the web, create a receiving groove which receives the edge region pointing in the direction of the housing. In this respect, the two legs encompass the edge region of the lever head, whereas the part of the edge region pointing in the direction of the housing rests or almost rests on the web. This enables precise positioning of the tilting travel limiting device and improves its hold on the lever head.

[0012] It is further conceivable for the lever head to have an edge region pointing in the direction of the housing, and for the tilting travel limiting device to have a preferably L-shaped receiving angle, open in the direction of the edge region to be accommodated, for receiving the edge region of the lever head. The receiving angle is formed with two legs, one leg resting on the inside or outside of the edge region and the other leg being arranged on the edge of the edge region, preferably parallel to this. In this embodiment, the two legs create a receiving angle which receives the edge region pointing in the direction of the housing. This enables precise positioning of the tilting travel limiting device and improves its hold on the lever head.

[0013] Advantageously, the tilt-path limiting device can have at least one adhesive strip for attachment to the lever head. The adhesive strip serves to secure or reinforce the attachment between the receiving groove or the receiving angle of the tilt-limiting device and the lever head. For example, it is conceivable for the adhesive strip to be attached to one of the two legs of the receiving groove and thus, in the assembled state, to be arranged between this leg and the lever head. It is also conceivable for the adhesive strip to be arranged on the web of the receiving groove. Other arrangements of the adhesive strip are also conceivable, for example, on the inside or outside of the edge region of the lever head.

[0014] Furthermore, it is conceivable for the tilt-path limiting device to have at least one clamping section for fastening to the lever head that at least partially surrounds the lever head on the outside. The clamping section serves to secure or reinforce the fastening between the tilt-path limiting device and the lever head.

[0015] In addition, the tilt-travel limiting device can have a clamping section at each of its two opposite ends for attachment to the lever head, at least partially enclosing the lever head on the outside. The clamping section serves to secure or reinforce the attachment between the tilt-travel limiting device and the lever head.

[0016] Advantageously, the tilting path limiting device can be formed by two separate elements, one element being designed as a stop element having a stop surface and the other element being designed as a connecting element forming the connection to the lever head, and the stop element being displaceable relative to the connecting element by means of an adjusting device. By displacing the stop element, the maximum possible tilting path can be limited and / or the limitation can be adjusted. The further the stop element is removed from the connecting element, the shorter the maximum possible tilting path. In this respect, the maximum amount of water flowing out through the outflow opening in the flow position is reduced.

[0017] It is also conceivable that the relative displacement between the stop element and the connecting element can be achieved by rotating the adjustment device. Rotating the adjustment device thereby displaces the stop element translationally in the direction away from the connecting element. The stop element does not undergo any rotational displacement. By moving the stop element, the maximum possible tilting path can be limited and / or the limitation can be adjusted. The further the stop element is removed from the connecting element, the shorter the maximum possible tilting path. In this respect, the maximum amount of water flowing out through the outflow opening in the flow position is reduced.

[0018] In addition, the tilting travel limiting device can have an electric motor and a power storage unit for motor-driven rotation of the adjustment device. Rotating the adjustment device translates the stop element in the direction away from the connecting element. The stop element does not undergo any rotational displacement. By moving the stop element, the maximum possible tilting travel can be limited and / or the limitation can be adjusted. The further the stop element is removed from the connecting element, the shorter the maximum possible tilting travel. This reduces the maximum amount of water flowing out through the outlet opening in the flow position.

[0019] Advantageously, the relative displacement between the stop element and the connecting element can be carried out by pressing the adjusting device. Pressing the adjusting device displaces the stop element translationally in the direction facing away from the connecting element. The adjusting device therefore acts in a similar way to the ballpoint pen mechanism of a push-button ballpoint pen. In this respect, the adjusting device can act, for example, like a locking tensioning mechanism, which has springs that can assume two stable positions and maintain them without the influence of external forces. By pressing the adjusting device, a first stable position can be assumed in which the stop element is away from the connecting element. By pressing it again, a second stable position can be assumed in which the stop element is close to the connecting element.Pressing the adjustment device merely moves the stop element translationally in the direction away from the connecting element. The stop element does not undergo any rotational displacement. By moving the stop element, the maximum possible tilting travel can be limited and / or the limit can be adjusted. The further the stop element is removed from the connecting element, the shorter the maximum possible tilting travel. This reduces the maximum amount of water flowing out through the outlet opening in the flow position.

[0020] It is also conceivable that the relative displacement between the stop element and the connecting element can be carried out by pivoting the stop element. In this design, the adjustment device is designed as a pivoting joint which connects the stop element to the connecting element. When the stop element is pivoted, the stop surface, which is spaced apart from the adjustment device by the length or thickness of the stop element, is deflected towards the housing. By displacing the stop element, the maximum possible tilting path can be limited and / or the limitation can be adjusted. The further the stop surface of the stop element is away from the connecting element, the shorter the maximum possible tilting path. In this respect, the maximum quantity of water flowing out through the outflow opening in the flow position is reduced.

[0021] In addition, the surface of the web facing away from the receiving groove can form the stop surface. This makes the design of the tilt-limiting device less complicated and more robust. Advantageously, the tilt-limiting device can be made at least partially, preferably entirely, of plastic, metal, or a similar material. A plastic design has the particular advantage that the tilt-limiting device is lightweight and does not damage the water fitting.

[0022] If, in the maximum possible flow position, the tilting path limiting device strikes the lever head directly or indirectly with at least one stop surface, it is advisable if the lever head has an edge region pointing in the direction of the housing at least in the region facing away from the outlet opening and the tilting path limiting device is fastened to the housing, preferably on the side facing away from the outflow opening, in such a way that the stop surface is aligned in the direction of the edge region of the lever head.

[0023] Furthermore, the tilting travel limiting device can comprise a stop element having a stop surface and a connecting element forming the connection to the housing and having a mounting surface. The stop element can be displaced relative to the connecting element by means of an adjustment device. The maximum permissible tilting travel can be adjusted by means of the relative displacement.

[0024] The connecting element can be designed as a profile rail comprising a web and at least one sliding flange projecting on one side of the web and having an inner surface facing the web and an outer surface facing away from the web, wherein the inner surface has, at least in a partial area, a toothing, preferably extending parallel to the web, and wherein the adjusting device has counter-toothing that interacts with the toothing of the connecting element. wherein the adjusting device can be moved against a restoring force from its toothing position to its displacement position in order to release the connection between the toothing of the connecting element and the counter-toothing of the adjusting device for the purpose of relative displacement of the stop element relative to the connecting element. If a sliding flange is provided on each side of the web, the profile rail has a type of double-T profile.

[0025] The adjustment device can have a receiving area for receiving the profile rail, wherein the receiving area comprises a slot corresponding to the web and an undercut for each sliding flange corresponding to the respective sliding flange. In such a configuration, the adjustment device is designed like a slide that can be moved along the profile rail.

[0026] It is advisable that, when the adjustment device is in its toothing position, a free space of height h is provided between the housing or the mounting flange with the mounting surface on the one hand and at least the area of ​​the adjustment device having the counter-toothing on the other hand, wherein height h corresponds at least to the required displacement path of the adjustment device to release the connection between the toothing of the connecting element and the counter-toothing into its displacement position. If the stop element is to be moved relative to the connecting element, the adjustment device is pressed. In this way, the connection between the toothing of the connecting element and the counter-toothing is released and the stop element can be moved, for example shifted, relative to the connecting element.

[0027] The adjusting device can be made of an elastic material, at least in the area having the counter-toothing. An elastic material is understood to be a material that changes its shape under the application of force and returns to its original shape when the applied force is removed. To release the connection between the toothing of the connecting element and the counter-toothing of the adjusting device for the purpose of relative displacement of the stop element with respect to the connecting element, the adjusting device is compressed in the elastically designed area. After displacement and subsequent removal of the applied pressure, the elastic material returns to its original shape, so that the connection between the toothing of the connecting element and the counter-toothing of the adjusting device is restored.

[0028] The adjusting device can consist of two resiliently interconnected partial sections, viewed in the longitudinal extension of the receiving region, forming a pivoting region, and the adjusting device can consist of a resilient material at least in the pivoting region, wherein the partial section has the counter-toothing and can be displaced from its toothing position into its displacement position against a restoring force.

[0029] The adjustment device and the stop element can be designed as a single piece.

[0030] The tilt travel limiting device can have a push button for moving the adjustment device.

[0031] The tilt limiting device can have at least one adhesive strip on its mounting surface for attaching the tilt limiting device to the housing. This allows the tilt limiting device to be easily adhered to a housing without the need for tools and can be removed just as easily.

[0058] In all figures, identical reference symbols are used for identical or similar components.

[0059] Fig. 1 a, Fig. 1 b and Fig. 1 c show a water fitting 1 comprising a housing 2 with a water connection (not shown) and with an outlet opening 3. Also not shown is a cartridge arranged in the housing 2. The cartridge has, in the region of its upper end, a tiltable adjustment element protruding from the upper side of the housing 2.

[0060] 4 and a lever head 5 connected to the adjusting element 4.

[0061] The lever head 5 can be tilted between its shut-off position, in which the water fitting 1 is closed and no water flows out of the outlet opening 3, and a flow position in which water flows out of the outlet opening 3. Fig. 1 a shows the lever head 5 in its shut-off position, whereas Fig. 1 c shows the lever head 5 in its maximum flow position.

[0062] Furthermore, Fig. 1a and Fig. 1b show, among others, a tilting path limiting device 7, which serves to reduce the maximum amount of water flowing out through the outflow opening 3 in the flow position. The tilting path limiting device 7 is detachably arranged and has a stop surface 6. In the maximum possible flow position shown in Fig. 1b, the tilting path limiting device 7 strikes with its stop surface 6 directly against the housing 2 and in this way reduces the maximum possible tilting path of the lever head 5 from its shut-off position to its flow position.

[0063] The lever head 5 has an edge region 8 pointing in the direction of the housing 2. The tilting path limiting device 7 comprises a U-shaped receiving groove 9 open in the direction of the edge region 8. The receiving groove 9 serves to receive the edge region 8 of the lever head

[0064] 5 and consists of two legs 11 connected to one another by a web 10 and arranged at a distance from one another. The surface of the web 10 facing away from the receiving groove 9 forms the stop surface 6.

[0065] Comparing Fig. 1b and Fig. 1c, it is evident that the tilting path limiting device 7 significantly reduces the maximum angle of inclination (a, b) of the lever head 5. The lower maximum angle of inclination reduces the maximum tilting path. Thus, the maximum angle of inclination (a) of the lever head 5 in Fig. 1b, i.e., with the tilting path limiting device 7, is significantly smaller than the maximum angle of inclination (b) of the lever head 5 in Fig. 1b. Therefore, the reduced angle of inclination (a) in Fig. 1b and the resulting reduced tilting path of the lever head 5 reduce the maximum amount of water flowing out through the outflow opening 3.

[0066] Fig. 2a, Fig. 2b, Fig. 2c and Fig. 2d each show a detailed section of various embodiments of a water fitting 1 according to the invention with a lever head 5 and a tilting travel limiting device 7. In these illustrated embodiments, the tilting travel limiting device 7 is formed by two separate elements, one element being designed as a stop element 12 having the stop surface 6 and the other element as a connecting element 13 forming the connection to the lever head 5. The stop element 12 is displaceable relative to the connecting element 13 by means of an adjusting device 14.

[0067] Fig. 2a shows an embodiment of the tilting travel limiting device 7, in which the relative displacement between the stop element 12 and the connecting element 13 can be carried out by rotating the adjusting device 14. The adjusting device 14 is designed as a type of screw and has a thread. The thread causes the stop element 12 to move away from the connecting element 13 when the adjusting device 14 is rotated in one direction along the adjusting device 14 and to move towards the connecting element 13 when the adjusting device 14 is rotated in the other direction along the adjusting device 14. If the stop element 12 is moved away from the connecting element 13, the distance between the housing 2 (not shown here) and the stop surface 6 is reduced. In this respect, the maximum tilting travel is also reduced.When shifting in the opposite direction, the maximum possible tilting path is increased again, but it still remains smaller than the maximum possible tilting path without a tilting path limiting device 7.

[0068] Fig. 3a shows the same object as Fig. 2a. In contrast to the embodiment according to Fig. 2a, the tilting path limiting device 7 according to Fig. 3a has an adhesive strip 17 in addition to the attachment to the lever head 5. The adhesive strip 17 connects the receiving groove 9 to the lever head 5.

[0069] Fig. 2b shows an embodiment of the tilting travel limiting device 7, in which the tilting travel limiting device 7 has an electric motor 15 and a power storage device 16 for motor-driven rotation of the adjusting device 14. The adjusting device 14 therefore has a thread. The thread causes the stop element 12 to move away from the connecting element 13 when the adjusting device 14 is rotated in one direction along the adjusting device 14 and to move towards the connecting element 13 when the adjusting device 14 is rotated in the other direction along the adjusting device 14. If the stop element 12 is moved away from the connecting element 13, the distance between the housing 2 (not shown here) and the stop surface 6 is reduced. In this respect, the maximum tilting travel is also reduced.If the movement is in the opposite direction, the maximum possible tilting distance is increased again, but it still remains smaller than the maximum possible tilting distance without the tilting distance limiting device 7.

[0070] Fig. 3b shows the same object as Fig. 2b, wherein the tilting path limiting device 7 according to Fig. 3b again has an adhesive strip 17 in addition to the attachment to the lever head 5. The adhesive strip 17 connects the receiving groove 9 to the lever head 5.

[0071] Fig. 2c shows an embodiment of the tilt travel limiting device 7, in which the relative displacement between the stop element 12 and the connecting element 13 can be carried out by pressing the adjusting device 14. The adjusting device 14 acts in a similar way to the ballpoint pen mechanism of a push-button ballpoint pen. In this respect, the adjusting device 14 acts like a locking tensioning mechanism which has springs. The adjusting device 14 allows the setting of two stable positions. By pressing the adjusting device 14, a first stable position can be assumed in which the stop element 12 is away from the connecting element 13. By pressing it again, a second stable position can be assumed in which the stop element 12 is close to the connecting element 13. The first pressing of the adjusting device 14 merely displaces the stop element 12 translationally in the direction facing away from the connecting element 13.Pressing the adjustment device 14 a second time merely displaces the stop element 12 translationally in the direction facing the connecting element 13. The stop element 12 does not undergo any rotational displacement. If the stop element 12 is moved away from the connecting element 13, the distance between the housing 2 (not shown here) and the stop surface 6 is reduced. Accordingly, the maximum tilting travel is also reduced. Upon displacement in the opposite direction, the maximum possible tilting travel is increased again, but it still remains smaller than the maximum possible tilting travel without the tilting travel limiting device 7.

[0072] Fig. 3c shows the same object as Fig. 2c, wherein the tilting path limiting device 7 according to Fig. 3c again has an adhesive strip 17 in addition to the attachment to the lever head 5. The adhesive strip 17 connects the receiving groove 9 to the lever head 5.

[0073] Fig. 2d shows an embodiment of the tilt-path limiting device 7, in which the relative displacement between the stop element 12 and the connecting element 13 can be achieved by pivoting the stop element 12. In the illustrated state, the stop element 12 is adjusted such that the tilt path is maximally limited. In this respect, the stop surface 6 is spaced away from the connecting element 13 by the thickness of the stop element 12 and the gap between the stop element 12 and the connecting element 13. Starting from this state, the stop element 12 can also be "pivoted out" so that the stop surface 6 no longer strikes the housing 2 in the event of tilting. This increases the maximum possible tilt path, but is still smaller than the maximum possible tilt path without the tilt-path limiting device 7.

[0074] Fig. 3d shows the same object as Fig. 2d, wherein the tilting path limiting device 7 according to Fig. 3d again has an adhesive strip 17 in addition to the attachment to the lever head 5. The adhesive strip 17 connects the receiving groove 9 to the lever head 5.

[0075] Fig. 4a and Fig. 4b show an alternative embodiment of a tilting path limiting device 7. The tilting path limiting device 7 again comprises the U-shaped receiving groove 9 which is open in the direction of an edge region 8 (not shown) and which is formed by the two by the web

[0076] 10 interconnected, spaced-apart legs 11. The receiving groove 9 serves to receive the edge region 8 of the lever head 5. The surface of the web 10 facing away from the receiving groove 9 forms the stop surface 6. In the illustrated embodiment, the width of the receiving groove 9 increases slightly towards its free end. This makes it easier to slide it onto the edge region 8 of the lever head 5. The leg 11 resting on the outside of the lever head 5 has, in the region of its two opposite ends, a clamping section 18, 19 each approximately adapted to the contour of the lever head 5. By means of these clamping sections 18, 19, the tilt travel limiting device 7 can be detachably attached to a lever head 5. The clamping sections 18, 19 act like a clasp which clamps around the lever head 5 over a length which is greater than half the circumference of the lever head 5.In addition, an adhesive strip 17 can also be used for fastening to the edge area 8 of a lever head 5, for example on the inside of one of the two legs.

[0077] 11 may be provided. In this respect, the tilting path limiting device 7 shown has two clamping sections 18, 19 for fastening to a lever head 5, partially enclosing the outside of a lever head 5. Figs. 5a and 5b show a side view and a rear view of a water fitting 1 with a tilting path limiting device 7 in its shut-off position. The tilting path limiting device 7 is the tilting path limiting device 7 shown in Figs. 4a and 4b. As can be seen from the figures, the clamping sections 18, 19 of the tilting path limiting device 7 partially enclose the outside of the lever head 5, specifically over a length that is greater than half the circumference of the lever head 5. The tilting path limiting device 7 is thus detachably fastened to the lever head 5.

[0078] 6 to 18 show a further embodiment of a tilting travel limiting device 7 according to the invention. The tilting travel limiting device 7 is fastened to the housing 2 of a water fitting 1 (not shown) on the side facing away from the outflow opening 3 in such a way that the stop surface 6 is oriented in the direction of the edge region 8 of the lever head 5. The lever head 5 has, at least in the region facing away from the outlet opening 3, an edge region 8 pointing in the direction of the housing 2. In the maximum possible flow position, the tilting travel limiting device 7 strikes with the stop surface 6 directly against the lever head 5, namely in the edge region 8.

[0079] The tilting path limiting device 7 in turn comprises the stop element 12 having the stop surface 6 and the connecting element 13 forming the connection to the housing 2 and having a mounting surface 20, wherein the stop element 12 is displaceable relative to the connecting element 13 by means of the adjusting device 14.

[0080] The connecting element 13 is designed as a profile rail, as can be seen, for example, in Figs. 10 to 13. It has a web 21 and, on each side of the web 21, a projecting sliding flange 22, wherein each sliding flange 22 has an inner surface facing the web 21 and an outer surface facing away from the web 21. The inner surface of both sliding flanges 22 has, in a partial area, a toothing 23 extending parallel to the web 21. At its opposite end, the web 21 has a further mounting flange forming the mounting surface 20. The profile rail is thus designed in the manner of a double-T profile. An adhesive strip 17 for fastening the tilt travel limiting device 7 to the housing 2 is provided on its mounting surface 20.

[0081] The adjusting device 14 has, as can be seen, for example, in Figs. 14 and 15, a counter-toothing 24 that interacts with the toothing 23 of the connecting element 13. As Figs. 14 and 15 show, the adjusting device 14 has a receiving area for receiving the profile rail, wherein the receiving area comprises a slot 25 corresponding to the web 21 and, for each sliding flange 22, an undercut 26 corresponding to the respective sliding flange 22. The adjusting device 14 is thus designed in the manner of a carriage that can be moved along the profile rail.

[0082] The adjusting device 14 consists, viewed in the longitudinal extension of the receiving area, of two sections 28, 29 resiliently connected to one another to form a pivoting area 27, wherein the adjusting device 14 is made of a resilient material at least in the pivoting area 27. The section 29 has the counter-toothing 24 and can be displaced from its toothed position into its displacement position against a restoring force. The pivoting area 27 is formed by an incision. As a result of the incision, this area (pivoting area 27) is thinner, so that the two sections 28, 29 can pivot relative to one another in the pivoting area 27. The pivoting area 27 thus forms a type of hinge. The adjusting device 14 can, for example, be made of a plastic.

[0083] As can be seen from Fig. 10, for example, the tilting travel limiting device 7 has a pusher 30 for displacing the adjusting device 14. The pusher 30 acts on the partial section 29, which can be displaced against a restoring force and has the counter-toothing 24. As shown in Fig. 8, for example, when the adjusting device 14 is in its toothing position, a free space 31 with the height h is provided between the mounting flange with the mounting surface 20, on the one hand, and the region of the adjusting device 14 having the counter-toothing 24, on the other hand. The height h corresponds at least to the required displacement path of the adjusting device 14 to release the connection between the toothing 23 of the connecting element 13 and the counter-toothing 24 into its displacement position.

[0084] If a relative displacement between the stop element 12 and the connecting element 13 is desired, the adjusting device 14 is pressed. For this purpose, pressure is exerted on the pusher 30. As a result, the area of ​​the adjusting device 14 having the counter-toothing 24, namely the section 29, is displaced in the direction of the mounting flange with the mounting surface 20, thus releasing the connection between the toothing 23 of the connecting element 13 and the counter-toothing 24. The stop element 12 can then be displaced relative to the connecting element 13. Once the stop element 12 is in its desired position, no further pressure is exerted on the pusher 30.Due to the resilient design, the section 29 of the adjusting device 14 having the counter-toothing 24 is displaced back into its original position, so that the connection between the toothing 23 of the connecting element 13 and the counter-toothing 24 of the adjusting device 14 is restored.

[0085] In the illustrated embodiment, the adjusting device 14 and the stop element 12 are formed in two parts. The pusher 30 has two pins 32 on its underside, which, when assembled, are inserted into holes 33 in the section 29 of the adjusting device 14.
