The present invention relates to an actuating arrangement for a drain valve of a cistern according to the preamble of claim 1. Furthermore, the invention relates to a cistern according to claim 16 and claim 17 and a method for assembling an actuating arrangement according to claim 18.

STATE OF THE ART

From the EP 2 388 380 an actuating arrangement has become known in which an actuating plate with actuating buttons flush with a wall, in which the actuating plate is installed, can be aligned. For alignment, a spacer armature is provided which communicates with a plate and cooperates with an adjusting element.

From the pamphlets EP 0 544 616 . DE 20 2007 002924 . DE 20 2013 007881 . EP 1 647 638 and EP 0 905 328 Further actuation arrangements have become known.

Although good results have been achieved in the assembly and the orientation of the actuator plate, it has been shown that the actuator assembly is not flexible enough to use with respect to the different structures of preambles.

PRESENTATION OF THE INVENTION

Based on this prior art, the invention has for its object to provide a, in particular flush-mounted, actuating arrangement, which overcomes the disadvantages of the prior art. In particular, the actuator assembly should be more flexible with respect to wall structures of different thicknesses.

Such an object is achieved by the actuation arrangement according to claim 1. Accordingly, an actuation arrangement for a drain valve of a cistern comprises an actuation unit with which a flushing process can be triggered, and at least one spacer which extends along a spacer axis and which communicates with a front end with the actuation unit and with the opposite rear end directly or indirectly connectable to the cistern. The spacer is designed to be cut to length in a predetermined grid size.

By arranging the cut-to-length spacer, the installer can adjust the distance between the cistern and the operating unit fixedly disposed behind a pretext such that the operating unit can be positioned with the front relative to the pretext. The ablängbaren spacer, the actuator assembly can be much more flexible, especially for preambles of different thickness, are used. The installer is provided by the cutting or shortening of the spacer in the predetermined grid a very easy-to-use solution for positioning the actuator relative to the pretext.

The spacer is formed in cross-section transverse to the Distanzhalteachse seen substantially U-shaped with a base leg and two protruding from the base leg side legs. This U-shaped design has the advantage that the operating unit can be well supported.

The actuating unit is formed substantially rectangular when viewed in the direction of the distance holding axis, wherein exactly two separately formed spacers are arranged, whose base legs are parallel to each opposite sides of the rectangle. Preferably, the two spacers are formed substantially identical to each other.

The actuation unit preferably comprises at least one actuation sensor or at least one actuation key, via which the flushing can be triggered.

Preferably, the spacer comprises a base element for connecting the Spacer with the actuator and at least one of the base member in the direction of the Distanzhalteachse subsequent and the grid dimension defining distance holding element, which communicates with the base member via at least one connection point, preferably in the form of a connecting web. The spacer element can be connected directly or indirectly with the cistern.

The base element thereby provides the front end and the spacer element provides the rear end. The base element is connected to the actuating unit and the spacer element is connected to the cistern directly or indirectly via another element.

The predetermined grid size is preferably in the range of 2 to 10 millimeters. Particularly preferred at 5 to 10 millimeters, in particular 6 or 8 millimeters.

Particularly preferably, the base element is adjoined by a multiplicity of identically designed spacer holding elements, which in each case communicate with the preceding distance holding element via at least one connection point.

Between two connection points and also between two adjacent distance holding elements or between the base element and the directly following distance holding element in each case a materialless space is present. In other words, the spacer elements are spaced from one another or the base element and the spacer element each with a gap to each other and are exclusively via the connection points with each other.

The spacer is preferably formed in one piece. The base element and the at least one spacer element and the connection points are formed as an integral part. The length of this integral part can be shortened or shortened by breaking or disconnecting the joints.

Particularly preferably, the spacer is designed as a plastic injection-molded part.

Preferably, the at least one connection point between the base member and the spacer element or between the spacer element and the adjacent spacer element formed with predetermined breaking points. Particularly preferably, the predetermined breaking points are separable without tools.

Preferably, the predetermined breaking point lies directly on the adjacent spacer holding element, which is located at a smaller distance from the base element. This ensures when cutting to length that the spacer element or the base element, which comes directly or indirectly in communication with the cistern, has no residues of the connection points.

Particularly preferably, each of the spacer elements and preferably also the base element comprises latching means, in particular at least one latching recess, so that the spacer can be connected directly or indirectly to the flushing box via a latching connection. Since the spacer is connected to the front end with the actuating unit, it can also be said that in this advantageous embodiment, the actuating unit is connected via a latching connection with the cistern directly or indirectly.

Particularly preferably, the spacer and / or the base member and / or the spacer elements is designed as a cut-border, which surround a frame opening in the actuator unit only partially but not completely surrounds. It is therefore a partially interrupted enclosure. The enclosure thus has at least one intermediate space. The formation of the spacer as abwegable and partially interrupted enclosure has the advantage that a mechanically stable element is provided, with which the position of the actuator unit can be adjusted, at the same time the installation or removal of components in the cistern through the frame opening or not only minimally hindered. Consequently, it is a further object of the invention to provide an actuator assembly which allows easy adjustment of the position and the stable storage of the operating unit, while access to the cistern should not be hindered in the case of revision.

Preferably, the base leg of the spacer is parallel to the width of the Rectangles and the side legs are parallel to the length. The side legs are preferably shorter, more preferably substantially shorter than half the length of the rectangle. This design has the advantage that the side legs do not completely surround the rectangle so that space can be created for mounting or dismounting for cistern components.

The spacer is preferably connected to the actuating unit via at least one adjusting element, the distance and position between the spacer and the actuating unit being adjustable via the adjusting element. By adjusting the distance and location between the spacer and the actuator unit, the installer can make a fine adjustment, so that the actuator unit can be aligned with its front side substantially flush with the wall.

Particularly preferably, the maximum adjustable distance of the adjusting element substantially corresponds to the simple grid size or corresponds to at most twice the grid size.

Preferably, the adjusting element is a screw with a screw head and an adjoining threaded shaft, the screw head being rotatable in at least one screw head receptacle on the actuating unit and fixedly mounted on the actuating unit with respect to a movement in the direction of the threaded shaft. The threaded shank engages in a threaded receptacle arranged on the base element. By rotating the screw, the distance between the screw head and the screw receptacle in the base element is changed, which leads to a change in the distance between the base element and the actuating unit due to the mounting of the screw head in the screw receptacle.

Particularly preferred exactly four screws are arranged at the respective corners of the rectangular actuating unit.

Particularly preferably, the actuating unit comprises a mounting frame with a central frame opening bounded by frame webs and a mounted in the mounting frame actuator module with the operation buttons or actuation sensors. The Actuating module is preferably latched to the mounting frame, wherein the mounting frame for this purpose has a latching cam.

Through the frame opening access to the cistern can be provided when the actuator module has been removed from the mounting frame. The frame opening thus serves as a revision opening.

Preferably, the mounting frame on said at least one screw head receptacle. Consequently, the spacer elements are on the adjustment, which are stored in the arranged on the mounting frame screw head receptacle, on the mounting frame with the actuator in combination.

Particularly preferably, the at least one spacer is seen in the direction of the distance holding axis outside the clear width of the frame opening, preferably in the region of the frame webs. Consequently, the at least one spacer is arranged such that it does not prevent access through the frame opening to the cistern.

Preferably, the actuating device further comprises a connection frame, which is connectable to the cistern and which has a receptacle for the spacer into which receptacle of the spacer, in particular with the spacer element or the base member protrudes. The connection frame serves the said indirect connection of the actuator unit with the cistern. In alternative embodiments, the connection frame can be dispensed with, wherein the cistern then has a corresponding receptacle for the spacer element or the base element, wherein it then comes to said direct connection with the cistern.

Particularly preferably, the receptacle of the connecting frame has locking means, in particular locking tongues, which cooperate with the locking means of the base element or the at least one spacer element.

The particularly preferred embodiment of the actuating device comprises in Substantially seen from the cistern, the said connection frame, at least one of said spacers, which is in communication with the connection frame, said mounting frame, which communicates with the spacer, and arranged in the mounting frame actuating module.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the FIG. 1 an actuator assembly 1 for a drain valve of a cistern is shown. With the actuator assembly 1, a drain valve can be operated within the cistern, so that a sanitary fitting, such as a toilet or a urinal, rinse water can be supplied.

The actuating arrangement 1 comprises an actuating unit 2 with at least one actuating button 3 or an actuating sensor, via which a rinsing process can be triggered. In the present embodiment, exactly two operation keys 3 are arranged. In alternative embodiments, the actuating unit 2 can also be designed without actuating buttons. Here then corresponding sensor elements are arranged on the actuating unit.

Further, the actuator assembly 1 comprises at least one extending along a spacer axis D spacer 4, which with its front end 5 with the Actuator 2 is in communication and with the opposite rear end 6 is directly or indirectly connected to the cistern. The spacer 4 is designed such that the spacer 4 is formed in a predetermined raster R ablängbar. The cut spacer 4 then has a length X. The spacer 4 thus has elements which correspond to the predetermined grid size R and which can be cut to length by the installer according to the needs during assembly. Thus, the installer can adjust the position of the operating unit 2 via the spacer 4 with respect to the cistern to which the spacer 4 is mounted directly or indirectly. The cistern thus serves as a reference for the position of the actuator unit. 2

In the figures, a mechanical actuator 2 is shown. As mentioned above, however, the actuating unit can also be an electrically formed or a pneumatically formed actuating unit. Particularly preferably, the actuating unit 2 comprises a mounting frame 18 and a mounted in the mounting frame 18 actuating module 25 with the operation buttons 3 or the actuation sensors. The mounting frame 18 serves to receive the actuating module 25 and the actuating module 25, the flushing can be triggered. The actuating module 25 is preferably firmly connected to the mounting frame 18. Particularly preferably via a latching connection.

Based on FIG. 3 Now, the structure of the spacer according to the present embodiment will be explained in more detail below. In the FIG. 3 the actuator unit 2 is shown without the actuator module 25, ie only with the mounting frame 18. The spacer 4 comprises in the present embodiment, a base member 7 for connecting the spacer 4 with the actuator unit 2. Here, the base member 7 for connecting the spacer 4 with the mounting frame 18. The base member 7 closes in the direction of the Distanzhalteachse D at least one grid R defining distance holding element 8 at. The spacer element 8 is connected via at least one connection point 9, preferably in the form of a connecting web, with the base member 7 in connection. The junction 9 is severed in the lengthening of the spacer according to the length to be cut. The spacer element 8 or the base element 7, when all spacer elements 8 have been separated from the base element 7, are directly or indirectly with the cistern connectable. In the direct connection, the spacer element 8 or the base element 7 is in direct contact with the cistern. In the figures, the indirect connection is shown, in which case the spacer element 8 and the base member 7 are indirectly connected via a connecting frame 21 with the cistern. The connecting frame 21, which in the FIG. 3 is shown is connected to the cistern. For this purpose, the connection frame 21 has corresponding connection means 26.

Particularly preferably, both the base element 7 and each of the spacer elements 8, the said grid dimension R on. In other words, the extension of the base member 7 and that of the spacer holding members 8 in the direction of the spacer axis D are respectively identical to each other.

Like in the FIG. 3 can be well recognized, the distance holding element 8, which is directly in the base member 7, a plurality of identically formed spacer holding elements 8 connects. In other words, the base element 7 is adjoined by a multiplicity of identically designed spacer holding elements 8, which in each case communicate with the preceding distance holding element 8 via a connection point 9. In the in FIG. 3 Shown embodiment, 9 distance holding elements 8 are arranged.

The connection points 9 between the base element 7 and the first distance holding element 8 or between subsequent distance holding elements 8 are preferably formed with predetermined breaking points. These predetermined breaking points are in particular separable without tools. The installer can therefore cut the distance holder 4 by a separation of not required distance holding elements 8 to the desired length in the predetermined grid R dimension. With regard to the connection point 9, the predetermined breaking point is arranged such that it lies directly on the adjacent distance holding element 8, which lies at a smaller distance from the base element 7. This prevents that parts of the connection points 9 remain at a breaking off or separating the unneeded spacer elements 8 on the spacer 4. In the region of the predetermined breaking point, the material thickness of the connection point 9 can be selected somewhat smaller.

In alternative embodiments but can also be dispensed with the predetermined breaking point. The installer can then disconnect the joints 9, for example with a knife.

The connection points 9 adjoin in the direction transverse to the Distanzhalteachse D at intermediate spaces 37. In other words, each of the connection point 9 adjoins a gap 37. The intermediate space 37 provides an interruption or a material-free point between two adjacent distance-holding elements 8 or between the first distance-holding element 8 and the base element 7. The connection points 9 have a cross-section with respect to the distance-holding axis D which is smaller than that of the distance-holding elements 8 or of the base element 7.

In the FIG. 3 can also be well recognized that each of the spacer elements 8, here also the base member 7, locking means 10 have. The locking means 10 serve to provide a latching connection with the cistern or with the connecting frame 21. The connecting frame 21 and the cistern have corresponding locking means. Particular preference is given to corresponding locking tongues 23, which engage in the recesses 11. The actuating unit 2 or the mounting frame 18 are thus connected via the locking means 10 so the locking recesses 11 and locking tongues 23 with the cistern or with the connecting frame 21.

The connecting frame 21, which also in the FIG. 5 is shown has an opening 27 in the present embodiment. The opening 27 serves to provide access in case of revision to the cistern. The opening 27 may also be referred to as a revision opening.

With regard to the shape of the spacer 4 or of the base element 7, it can be stated that this is essentially identical between the spacer 4 and the base element 7. The spacer 4 or the base element 7 or the spacer holding elements 8 are formed in cross-section transversely to the Distanzhalteachse D seen substantially U-shaped. Consequently, the spacer 4 and the base member 7 and the Distance support elements 8 a base leg 12 and two projecting from the base leg 12 side legs 13. The side legs 13 are inclined at an angle to the base leg 12. The angle between side legs 13 and base leg 12 is preferably at 90 degrees.

The operation unit 2 has a substantially rectangular shape when viewed in the direction of the spacer axis D. Particularly preferred are as in the FIG. 3 shown exactly two spacers 4 arranged. The base legs 12 of the spacers 4 each extend parallel to opposite sides B or L of the rectangle of the actuating unit 2. In other words, the two spacers 4 are relative to each other with respect to the rectangle. In the particularly preferred embodiment, the base leg 12 of the spacer 4 is parallel to the width B of the rectangle and the side legs 13 are parallel to the length L. The side legs 13 are shorter, in particular substantially shorter than half the length L of the rectangle formed. As a result, a gap 28 is created, which can be helpful in the removal or installation of components in the cistern. This space 28 may in the FIGS. 4 and 5 be recognized very well. In other words, the spacer 4 or the base element 7 or the spacer elements 8 is designed as a cut-away and discontinuous enclosure, which enclosure surrounds a frame opening 20 in the actuator unit 2 in sections but not completely. The enclosure is interrupted by said gap 28.

From FIG. 3 can be further recognized that the spacer 4 via an adjustment 14 with the actuator unit, here with the mounting frame 18, in conjunction. With the adjustment 14, the distance and the position between the spacer and the actuator unit 2, here at the mounting frame 18, set. In the present embodiment, exactly four adjustment elements 14 are arranged. The adjusting elements 14 are placed in such a way that they lie at the corners of the rectangle, which defines the basic shape of the actuating unit 2. Consequently, the installer can adjust the inclination and / or the distance of the operating unit 2 with respect to the spacers 4 by suitable actuation of the respective adjusting elements.

About the adjustment 14 can be, as in the FIG. 8d shown the front surface 39 of the Align operating unit 2 and the mounting frame 18 relative to the pretext. In particular, the alignment follows flush.

The maximum adjustable distance of the adjusting elements 14 essentially corresponds to the grid dimension R. In alternative embodiments, the maximum distance preferably corresponds to twice the grid dimension R. The installer can thus make a corresponding fine adjustment by the actuation of the adjusting elements 14, so that the mounting frame or the operating unit 2 at Installation can be well aligned.

In the FIG. 6 For example, a particularly preferred adjustment member 14 in the form of a screw is shown. The screw has a screw head 15 with an adjoining threaded shaft 16. The threaded shaft 16 engages in a threaded receptacle 24, which is arranged here on the base member 7, a. By rotating the screw 14, the distance between the screw head 15 and the base element 7 changes. The screw head 15 has a circumferential groove 29. About this groove of the screw head 15 is connected to the actuator unit 2 here with the mounting frame 18. The screw head 15 is mounted in a corresponding screw head receptacle 17 such that the screw 14 is rotatable about its central axis and is mounted with respect to a movement in the direction of the threaded shaft 16 fixed to the actuator unit 2. For this purpose, the shaft receptacle 17, which in the FIG. 7 shown in detail, a groove 29 matching counterpart 30. The counterpart 30 engages in the groove 29 a. In the present embodiment, the screw head receptacle 17 is a substantially circular opening 31 with a radial opening 32. The radial opening 32 thereby provides access to the circular opening 31. Furthermore, at least one cam 33 is arranged in the front area of the radial opening 32. The screw head 15 can be inserted along the arrow P in the screw head receptacle 17. In this case, the counterpart 30 engages in the groove 29 a. The cams 33 prevent the screw head 15 from sliding out of its screw head receptacle 17. When the screw head 15 is inserted along the direction of the arrow P, the screw head is slightly spring-deformed and then returns to its starting position. Thus, the screw head 15 is held in the screw head receptacle.

Of the FIGS. 4 and 5 can be well recognized that the actuator unit 2 in the present embodiment comprises a mounting frame 18. The mounting frame 18 serves to receive the actuating module 25. In the FIGS. 4 and 5 the mounting frame 18 is shown without the actuator module. In the Figures 1 and 2 is the actuation module used accordingly. The mounting frame 18 includes a peripheral frame web 19 of a frame opening 20 limited. Through the frame opening 20 access to the interior of the cistern can be created. The actuating module 25 is preferably latched in the mounting frame, wherein the mounting frame here has a latching cam 34. Other types of attachment of the actuating module 25 in the mounting frame 18 are also conceivable.

As already mentioned, in the present embodiment, the mounting frame 18 comprises said at least one screw head receptacle 17. The spacer 4 is arranged with respect to the frame opening 20 so that it lies outside the clear width of the frame opening 20 in the direction of the spacer axis D. In other words, the spacer 4 thus does not reduce the frame opening 20, and it is still possible to provide good access to the inspection opening on the cistern. The spacers 4 are preferably in the region of the frame webs 19, so that when viewed in the direction of the Distanzhalteachse D are not visible.

If the actuator unit 2 is connected via the connecting frame 21 with the cistern, as in the embodiment of the FIG. 5 is shown, the spacers 4 are also arranged with respect to the opening 27 in the connecting frame 21 such that they do not protrude into the inside width of the opening 27 of the connecting frame 21.

Based on FIGS. 8a to 8d Now single assembly steps for the inventive actuator 1 are shown. According to a first step in the FIG. 8a is shown, the distance X between the foremost surface 35 of a prewall and a contact surface 36 between the spacer and the cistern is measured. Here, the contact surface 36 is part of the connecting frame 21. However, it can also be part of the cistern. The distance X corresponds to the distance to be cut. In a next step, which in the FIG. 8b is shown, the distance X is measured at the inventive actuator 1. In this case, the dimension X is measured from the front side 39 of the actuating unit 1 and then the spacer 4 is cut to length on the basis of the measured distance X and the removing spacer elements 8 are separated.

The thus prepared actuator 1 is then inserted into the opening in the pretext. In this case, the spacer 4 comes with the contact surface 36 of the cistern or the connecting frame 21 in contact and is applied to this. This is in the FIG. 8c shown accordingly.

The mounting frame 18 or the actuating unit 2 can then optionally be fixed accordingly with a silicone seal in the recess in the pretext.

In a preferred but optional step, according to the FIG. 8d the adjusting elements 14 are actuated so that the front side 39 of the actuating unit 2 is flush with the surface of the pretext.
