- EP 1 995 386 discloses an actuating device of the generic type for the actuation of a drain fitting in a flushing cistern.
- the actuating device has a push-button housing in which two push buttons are mounted. When flushing is triggered, the push buttons here are moved downwards, the drain fitting being actuated to trigger flushing by this movement.
- the present invention is based on the object of providing an actuating device, the push button of which is alignable in relation to a cistern lid in which the actuating device is installed.
- an actuating device for a drain fitting of a flushing cistern comprises a housing, which is insertable into an opening of a cistern lid, having at least one push button, which is mounted in said housing so as to be movable along an axis in relation to the housing, and a pusher element, which is movable towards the drain fitting to trigger flushing by actuating the at least one push button.
- the housing comprises an assembly housing, by which the actuating device can be connected to the drain fitting and/or the flushing cistern, and a push-button housing, which is adjustably, in particular pivotably or rotatably mounted on the assembly housing, the at least one push button being mounted on the push-button housing.
- the actuating device is mounted in the flushing cistern by the assembly housing.
- the push-button housing is, therefore, pivotably or rotatably mounted in relation to the assembly housing, on account of which the push button mounted in the push-button housing can be aligned.
- the push-button housing can be adjusted in relation to the assembly housing.
- the position of the push-button housing and of the push buttons in relation to the cistern lid can be adjusted. This is particularly advantageous when, for example, two push buttons are present or when an imprint or embossing which is located on the push button, for example the logo of the manufacturer of the actuating device, is to be aligned.
- the push-button housing is in contact with the flushing cistern or the drain fitting exclusively via the assembly housing.
- a clutch in particular an overrunning clutch having a toothing and at least one blocking latch which engages in the toothing, is located between the assembly housing and the push-button housing.
- the overrunning clutch ensures that the relative movement between the push-button housing and the assembly housing can only take place in one direction. In the other direction, the relative movement between the assembly housing and the push-button housing is blocked, both the assembly housing and also the push-button housing being moved when a force acts in said other direction.
- the overrunning clutch may also be described as a one-way clutch.
- Said blocking latch interacts with the toothing, the relative movement between the assembly housing and the push-button housing being enabled in an overrunning direction, in particular after overcoming a friction force provided by the clutch, and the relative movement between the assembly housing and the push-button housing being disabled in a blocking direction, which is opposite to the overrunning direction.
- the movement occurs preferably about said axis.
- both the push-button housing and also the assembly housing are moved collectively.
- the push-button housing can move in relation to the assembly housing, in particular in the event that the latter is in a fixed position.
- the clutch permits the relative movement between the push-button housing and the assembly housing, and in the event of a movement acting on the push-button housing in the opposite direction, that is to say the blocking direction, the movement is blocked, the movement then being transmitted from the push-button housing to the assembly housing.
- the push-button housing can be aligned in relation to the assembly housing and, on the other hand, a rotation can also be applied to the assembly housing, said rotation being usable, for example, for the separation of the connection between the assembly housing and the drain fitting.
- the clutch provides a friction force which ensures that a movement is transmitted from the push-button housing to the assembly housing also in the event of a movement in the overrunning direction. Once this friction force is overcome, said overrunning takes place.
- a multiplicity of blocking latches are located at uniform spacing along the circumference.
- the toothing comprises a multiplicity of teeth, which are likewise located at uniform spacing along the circumference.

- the direction of rotation is defined in the viewing direction from above along the axis onto the surface of the push button which is visible from the outside. Consequently, the push-button housing can thus be aligned in relation to the assembly housing in the event of a movement in the clockwise direction.
- the clutch is blocked and the movement is transmitted from the push-button housing to the assembly housing.
- the assembly housing comprises a circular base plate and a side wall, which extends from the base plate along a central axis, the side wall terminating with an at least partially encircling flange.
- the flange preferably extends from the side wall towards the outside.
- the push-button housing comprises a cylindrical side wall having a collar portion, which projects from the side wall.
- the collar portion extends over the flange, the overrunning clutch being located between the collar portion and the flange.
- the collar portion thus covers the flange portion, so that said flange portion is not visible from outside.
- the base plate and the side wall of the assembly housing provide an interior space, into which the push-button housing at least partially protrudes. Consequently, the push-button housing is thus mounted in the interior space of the assembly housing.
- the push-button housing is rotatably mounted in the assembly housing, a securing element, which prevents an axial displacement between the push-button housing and the assembly housing, being provided between the push-button housing and the assembly housing.
- the securing element may be configured in various ways. It is particularly preferably a groove-and-ridge connection, the ridge protruding into the groove.

- the overrunning direction is clockwise and the blocking direction is anticlockwise.
- the reverse applies.
- the force is transmitted from the push-button housing via the friction present in the clutch to the assembly housing and, as soon as the thread is screwed into the drain fitting, slippage occurs in the clutch, so that the position of the push-button housing in relation to the now stationary assembly housing can still be adjusted.

Description
- The present invention relates to an actuating device for a drain fitting according to the preamble of
claim 1. -
EP 1 995 386 discloses an actuating device of the generic type for the actuation of a drain fitting in a flushing cistern. The actuating device has a push-button housing in which two push buttons are mounted. When flushing is triggered, the push buttons here are moved downwards, the drain fitting being actuated to trigger flushing by this movement. - Whereas exceptionally good results have been achieved with the actuating device according to
EP 1 995 386, the requirement has arisen for the push buttons to be alignable in relation to the cistern lid, such that, for example, a logo printed on the push button can be aligned in relation to the cistern lid. - The present invention is based on the object of providing an actuating device, the push button of which is alignable in relation to a cistern lid in which the actuating device is installed.
- Such an object is achieved by the actuating device according to
claim 1. Accordingly, an actuating device for a drain fitting of a flushing cistern comprises a housing, which is insertable into an opening of a cistern lid, having at least one push button, which is mounted in said housing so as to be movable along an axis in relation to the housing, and a pusher element, which is movable towards the drain fitting to trigger flushing by actuating the at least one push button. The housing comprises an assembly housing, by which the actuating device can be connected to the drain fitting and/or the flushing cistern, and a push-button housing, which is adjustably, in particular pivotably or rotatably mounted on the assembly housing, the at least one push button being mounted on the push-button housing. The actuating device is mounted in the flushing cistern by the assembly housing. The push-button housing is, therefore, pivotably or rotatably mounted in relation to the assembly housing, on account of which the push button mounted in the push-button housing can be aligned. - On account of the adjustability between the push-button housing and the assembly housing, the push-button housing can be adjusted in relation to the assembly housing. As a result, the position of the push-button housing and of the push buttons in relation to the cistern lid can be adjusted. This is particularly advantageous when, for example, two push buttons are present or when an imprint or embossing which is located on the push button, for example the logo of the manufacturer of the actuating device, is to be aligned.
- Preferably, the push-button housing is in contact with the flushing cistern or the drain fitting exclusively via the assembly housing.
- Preferably, a clutch, in particular an overrunning clutch having a toothing and at least one blocking latch which engages in the toothing, is located between the assembly housing and the push-button housing. The overrunning clutch ensures that the relative movement between the push-button housing and the assembly housing can only take place in one direction. In the other direction, the relative movement between the assembly housing and the push-button housing is blocked, both the assembly housing and also the push-button housing being moved when a force acts in said other direction. The overrunning clutch may also be described as a one-way clutch.
- Said blocking latch interacts with the toothing, the relative movement between the assembly housing and the push-button housing being enabled in an overrunning direction, in particular after overcoming a friction force provided by the clutch, and the relative movement between the assembly housing and the push-button housing being disabled in a blocking direction, which is opposite to the overrunning direction. The movement occurs preferably about said axis.
- In the event of a movement in the blocking direction acting on the push button or the push-button housing, both the push-button housing and also the assembly housing are moved collectively. In the event of a movement acting in the overrunning direction, the push-button housing can move in relation to the assembly housing, in particular in the event that the latter is in a fixed position.
- In other words, in the event of a movement acting on the push-button housing in the overrunning direction, the clutch permits the relative movement between the push-button housing and the assembly housing, and in the event of a movement acting on the push-button housing in the opposite direction, that is to say the blocking direction, the movement is blocked, the movement then being transmitted from the push-button housing to the assembly housing. On account of this, on the one hand the push-button housing can be aligned in relation to the assembly housing and, on the other hand, a rotation can also be applied to the assembly housing, said rotation being usable, for example, for the separation of the connection between the assembly housing and the drain fitting. For assembling, however, the clutch provides a friction force which ensures that a movement is transmitted from the push-button housing to the assembly housing also in the event of a movement in the overrunning direction. Once this friction force is overcome, said overrunning takes place.
- Preferably, a multiplicity of blocking latches are located at uniform spacing along the circumference. The toothing comprises a multiplicity of teeth, which are likewise located at uniform spacing along the circumference. The number of teeth is preferably greater than the number of blocking latches.
- Preferably, the toothing is located on the assembly housing and the at least one blocking latch is located on the push-button housing. The reverse arrangement is, however, also conceivable.
- Preferably, the overrunning direction is a movement in the clockwise direction and the blocking direction is a movement in the anticlockwise direction. The direction of rotation is defined in the viewing direction from above along the axis onto the surface of the push button which is visible from the outside. Consequently, the push-button housing can thus be aligned in relation to the assembly housing in the event of a movement in the clockwise direction. In the event of a movement in the anticlockwise direction, the clutch is blocked and the movement is transmitted from the push-button housing to the assembly housing.
- In a development of the invention, the assembly housing comprises a circular base plate and a side wall, which extends from the base plate along a central axis, the side wall terminating with an at least partially encircling flange. The flange preferably extends from the side wall towards the outside. Preferably, the push-button housing comprises a cylindrical side wall having a collar portion, which projects from the side wall.
- Particularly preferably, the collar portion extends over the flange, the overrunning clutch being located between the collar portion and the flange. The collar portion thus covers the flange portion, so that said flange portion is not visible from outside.
- Preferably, the base plate and the side wall of the assembly housing provide an interior space, into which the push-button housing at least partially protrudes. Consequently, the push-button housing is thus mounted in the interior space of the assembly housing.
- Preferably, the push-button housing is rotatably mounted in the assembly housing, a securing element, which prevents an axial displacement between the push-button housing and the assembly housing, being provided between the push-button housing and the assembly housing. The securing element may be configured in various ways. It is particularly preferably a groove-and-ridge connection, the ridge protruding into the groove.
- Preferably, the at least one push button is held in the starting position by a restoring element, in particular a compression spring, the restoring element being mounted preferably between the base plate and the push button.
- In a development of the invention, the assembly housing comprises a threaded portion having a thread, in particular having an external thread, with which the assembly housing is connectable to a drain fitting.
- Preferably, the pitch direction of the thread of the threaded portion is identical to the overrunning direction of the clutch. In the case of a right-handed thread, the overrunning direction is clockwise and the blocking direction is anticlockwise. In the case of a left-handed thread, the reverse applies. This has the effect that, when the clutch blocks the relative movement between the assembly housing and the push-button housing, rotation applied to the two housings enables the separation of the thread and the drain fitting. The threaded portion can thus be unscrewed from the counterpart in the drain fitting. The further effect is that when the clutch permits the relative movement between the assembly housing and the push-button housing, assembling of the thread and the drain fitting can be carried out. During assembling, the force is transmitted from the push-button housing via the friction present in the clutch to the assembly housing and, as soon as the thread is screwed into the drain fitting, slippage occurs in the clutch, so that the position of the push-button housing in relation to the now stationary assembly housing can still be adjusted.
- Further embodiments are provided in the dependent claims.
- Preferred embodiments of the invention are described in the following by means of the drawings, which are intended to be merely of a descriptive nature and not to be interpreted as limiting. In the drawings:

By means of theactuating device 1, a force or a movement can be applied to thedrain fitting 9, this subsequently leading to triggering of flushing. Upon triggering of flushing, a valve body of thedrain fitting 9 is raised from a valve on the flushing cistern, and the water can flow out from the flushing cistern to a toilet or a urinal via said valve. - The
actuating device 1 comprises ahousing 2, which is insertable into anopening 3 of acistern lid 4. The actuating device further comprises at least onepush button 5, which is mounted in saidhousing 2 so as to be movable along an axis M in relation to thehousing 2.

The push-button housing 8 is adjustably mounted on or in theassembly housing 7. In the present embodiment, the push-button housing 8 is pivotable or rotatable about the central axis M in relation to theassembly housing 7. The at least onepush button 5 is mounted on the push-button housing 8. - A clutch 10 is present between the
assembly housing 7 and the push-button housing 8. The clutch 10 is preferably an overrunningclutch 10 having atoothing 11 and having at least one blockinglatch 12, which engages in thetoothing 11. The overrunningclutch 10 may also be described as a one-way clutch. - The
toothing 11 and the blockinglatch 12 are correspondingly shown inFIGS. 4 and 5 . The clutch has the function of permitting the relative movement between the push-button housing 8 and theassembly housing 7 when a movement acts on the push-button housing 8 in a first direction or overrunning direction, here in the clockwise direction UZ. The relative movement is in particular permitted after overcoming the friction force which is made available by thetoothing 11 and the blockinglatch 12. The actual overrunning thus only commences when a sufficiently great force acts between the push-button housing 8 and theassembly housing 7, and the blockinglatch 12 is moved out of thetoothing 11. Consequently, the fitter can adjust the position of the push-button housing 8 in relation to theassembly housing 7 with a rotation in the overrunning direction. In the event that a movement acts on the push-button housing 8 in a second direction opposite to the first direction, here indicated by GUZ, the relative movement between the push-button housing 8 and theassembly housing 7 is not permitted, or is blocked. The second direction here may be described as the blocking direction. Consequently, the movement is correspondingly transmitted from the push-button housing 8 to theassembly housing 7. - It can be seen from
FIG. 4 that a multiplicity of blocking latches 12 are located at uniform spacing along the circumference. Twelve blocking latches 12 are located in the present embodiment. It is, however, also conceivable to locate fewer or more than twelve blocking latches 12. Thetoothing 11 has a multiplicity of teeth, which are also located at regular spacing along the circumference of theassembly housing 7. The finer the pitch of the teeth of thetoothing 11, the more precisely the position of thepush button 5 or the push-button housing 8 can be adjusted in relation to theassembly housing 7. - The
toothing 11 is thus preferably located on theassembly housing 7, and the at least one blockinglatch 12 is preferably located on the push-button housing 8. The arrangement may, however, also be reversed. - The overrunning direction UZ is preferably a movement in the clockwise direction, and the blocking direction GUZ is preferably a movement in the anticlockwise direction. The movements may, however, also be in the opposite sense.
- It can be seen from
FIG. 3 that theassembly housing 7 comprises acircular base plate 13 and aside wall 14 which extends from thebase plate 13 along a central axis M. Theside wall 14 here terminates with aflange 15, which is located so that it at least partially encircles the central axis M. Preferably, theflange 15 completely encircles the central axis M. Thebase plate 13 and theside wall 14 define aninterior space 18. - The push-
button housing 8 in the present embodiment comprises acylindrical side wall 16 having acollar portion 17 which projects from theside wall 16. Theside wall 16 delimits aninterior space 24, in which thepush button 5 is mounted. Thepush button 5 is mounted in the interior space so that it is movable along the central axis M. Furthermore, thepush button 5 is rotationally fixed in relation to the push-button housing 8. A rotation of thepush button 5 thus has the effect of a rotation of the push-button housing 8. To this end, thepush button 5 is in connection with the push-button housing 8 by suitable means, such as guide elements. - It can be seen from
FIG. 3 that thecollar portion 17 of the push-button housing 8 extends over theflange 15 of theassembly housing 7. Said clutch 10, in particular the overrunningclutch 10, is located here between thecollar portion 17 and theflange 15. In other embodiments, the clutch may, however, also be located in other places. Here, thetoothing 11 is located on the outer side of theflange 15, and the blocking latches 12 are located on the inner side of thecollar portion 17. - As a result of the
flange 15 being covered by thecollar portion 17, theflange 15 cannot be recognized from the outside, as is shown inFIG. 2 . From the outside, the user only sees thecollar portion 17 and thepush button 5. - The push-
button housing 8 at least partially protrudes into theinterior space 18 of theassembly housing 7. In other words, it may be said that the push-button housing 8 is mounted in theassembly housing 7. The mounting here is rotatably or pivotably configured, so that the push-button housing 8 can be rotated or pivoted about the central axis in relation to the assembly housing. A securingelement 19, which prevents an axial displacement between the push-button housing 8 and theassembly housing 7, is provided between the push-button housing 8 and theassembly housing 7 in the present embodiment. The securingelement 19 here has the form of a groove-and-ridge connection, the groove extending into theside wall 14 of theassembly housing 7 and the ridge extending away from theside wall 16 of the push-button housing 8. Other types of connection are of course also conceivable. - The present embodiment of the
actuating device 1 additionally comprises a restoringelement 20, by which the at least onepush button 5 is held in the starting position or returned again from the flushing position to the starting position. The restoringelement 20 is preferably located between thebase plate 13 and thepush button 5. Here, the restoringelement 20 has the form of a compression spring. - The
assembly housing 7 further comprises a threadedportion 21 having a thread, which threadedportion 21 here extends away from thebase plate 13 of theassembly housing 7 along the central axis M in relation to theinterior space 18. The threadedportion 21 comprises an external thread and anopening 26 extending along the central axis in which thepusher element 6 is movably mounted. Theassembly housing 7 can be connected to thedrain fitting 9 by the threadedportion 21, as this is shown inFIGS. 1 and 2 . To this end, thedrain fitting 9 likewise has a matching thread. - The
thread 25 has a pitch direction which is oriented identically to the overrunning direction. In the case of a right-handed thread, the overrunning direction is in the clockwise direction and the blocking direction is in the anticlockwise direction. Assembling will thus take place in the case of a rotation in the clockwise direction, the rotational movement being transmitted via the push-button housing 8 to theassembly housing 7 until said friction force of the clutch 10 is overcome. - In the context of disassembling this means that, when the clutch 10 blocks the relative movement between the
assembly housing 7 and the push-button housing 8, a rotation of the twohousings thread 21 anddrain fitting 9. In the case of a left-handed thread, which can likewise be used, the rotational directions are correspondingly reversed. - The
push button 5 is in connection with thepusher element 6 via acontact face 22. Thecontact face 22 here is oriented perpendicularly to the central axis M, so that thepush button 5 can be moved in relation to thepusher element 6 during the adjustment of the position of thepush button 5. - 1 Actuating device
