DESCRIPTION OF PREFERRED EMBODIMENTS

In the FIG. 1 an actuator 1 for a drain valve of a cistern is shown in plan view. The actuator 1 essentially comprises one in the FIG. 1 invisible mounting frame 2, an actuating button 3, and at least one actuator element 4, which here in the FIG. 1 is not visible. The actuator 4 is operable with the actuating button 3 and acts on the Spülauslösung in a cistern of a toilet or urinal. The flushing can thus be triggered via the actuator element 4.

In the embodiment of the FIG. 1 For example, the actuating key 3 essentially comprises two areas, namely a left area 5 and a right area 6. These two areas 5, 6 are separated by a visualized dividing line 7. A pressure by the user on the left area 5, which is shown here larger, triggers a full flush, while a pressure on the right area 6 triggers a corresponding partial flush. For this purpose, two actuator elements are arranged. The left and right areas can also be reversed accordingly.

The actuating button 3 is preferably formed as a flat plate with a front surface 11 and a rear surface 22. Particularly preferably, the actuating button 3 is formed essentially in one piece.

Preferably, the actuating device 1 comprises exactly one single actuating button 3. Thus, a particularly simple design of the actuating device can be provided with the possibility of triggering a dual-flushing.

Of the FIG. 2 , which shows the actuator 1 in a side view, can be well recognized that it is directly and directly to the mounting frame 2 in connection with the operating button 3 or directly and directly mounted on the mounting frame 2. By a direct and direct connection or storage is meant that the actuating button 3 without further elements, such as a frame or a cover plate, is connected directly to the mounting frame 2. Consequently, it can also be said that the operation button 3 is frameless or without cover plate. In this way it can be prevented that the actuating button 3 hooked to a mounting frame, as these are known from the prior art. Furthermore, a complex positioning between the actuating button 3 and the actuator element 4 is eliminated because the actuating button 3 can act on the actuator element 4 with the entire rear surface 22. In addition, eliminates the production and installation of a corresponding cover plate.

The actuating button 3 is relative to the mounting frame 2 in the Spülauslösung from an initial position to an end position movable, in particular pivotable formed. Consequently, therefore, the actuating button 3 can be moved from the starting position during the operation to the mounting frame 2 toward the end position. After flushing then the operation button 3 is away from the mounting frame 2, that is moved from the end position to the starting position.

The mounting frame 2 is typically embedded in an opening in a masonry and communicates with elements of the cistern. The wall opening 8 is in the FIG. 2 symbolically indicated. The wall opening 8 extends from a Wall 9 in said wall 9 into it. The wall 9 is set back relative to the actuating button 3, so that the actuating button 3 with respect to the wall 9 is movable. In other words, it can also be said that the actuating button is moved in the Spülauslösung from the starting position in the direction of wall 9 in the end position. The movement is represented by the arrow B.

Related to the FIG. 1 can be well recognized that the actuating button 3 seen in a direction perpendicular to the actuating button 3 is greater than the mounting frame and also larger than the wall opening 8 in the wall 9 is formed. Thus, the mounting frame 2 and the wall opening in a direction perpendicular to the surface 11 of the actuating button 3 is substantially completely covered by the actuating button 3, which in the FIG. 1 is clearly recognizable. The full coverage has the advantage that the user does not see the mounting frame 2 or parts of the wall opening 9 with built-in actuator 1, but only the surface of the actuating button 3 perceives, as in the FIG. 1 is shown accordingly. In addition, the training as a flat actuating button 3 is visually very appealing because the user perceives in use only a single element. Also, such an operation button 3 is easier to clean.

Also from the FIG. 2 can be well recognized that the actuating button 3 has a greater extent than the mounting frame. 3

The mounting frame 2 or the wall 9 define a plane 10. The plane 10 extends substantially parallel to the wall 9 and can be defined by corresponding elements of the mounting frame 2. For example, a circumferential flange 26 of the mounting frame, as this in the Figures 2 and 4 can be recognized, the said level 10 ready.

The mounting frame 2 comprises according to the FIG. 4 essentially an interior 27, which is bounded by a rear wall 28 and peripheral side walls 29. The side walls 29 then joins a circumferential flange 26 at. The rear wall 28 furthermore comprises at least one opening 30 through which elements can be guided in the direction of the cistern.

The actuating button 3 is preferably pivotable about at least one axis A1, A2, A3. There are essentially two different embodiments conceivable. In a first embodiment, the actuating button 3 is pivoted about exactly one axis A1. The axis A1 preferably runs centrally through the actuating button 3. In a second embodiment, the actuating button 3 is pivoted about two spaced apart axes A2, A3.

In the FIG. 1 All three axes A1, A2 and A3 are drawn. In the first embodiment, the actuating button 3 pivots on the plane 10 at a pressure on the left area 5 and the right area 6 about the axis A1. This is a kind of rocking movement in two different directions of pivoting about the axis A1. In the second embodiment, the actuating button 3 pivots at a pressure on the right area 6 about the axis A2 on the plane 10 back. At a pressure on the left area 5, the actuating button 3 pivots about the axis A3 with respect to the plane 10th

Upon actuation, the operation button 3 comes to rest with the surface 11 at an angle to the plane 10. With a view to FIG. 1 can also be said that the actuating button 3 is pivoted about the respective axis A1 or A2 or A3 at an angle to the sheet plane. The leaf level according to the FIG. 1 corresponds essentially to the plane 10, which is defined by the installation arms 2 and the wall 9.

The axes A1, A2, A3 can run both in the horizontal or in the vertical. It is also conceivable that the axes A1, A2, A3 extend at an angle or inclined to the horizontal or to the vertical. The dividing line 7 is then correspondingly printed in a different position in order to signal the user the direction of actuation. The dividing line 7 preferably runs parallel to the axes A1, A2, A3.

In the FIG. 3 For example, the actuating button 3 is shown in a rear perspective view with the rear surface 22 clearly visible. The in the FIG. 3 shown actuating button 3 is suitable for use as a first embodiment with an axis A1. The operation key 3 for use as a second embodiment with two axes A2, A3 is in the FIGS. 6a to 6c shown and then explained further below.

Of the Figures 3 . 4 and 7 can be seen that the mounting frame 2 and the actuating button 3 are connected to each other via bearings 12 and then communicate with each other via these bearings 12. Here, two bearings 12 are present, the actuating button 3 are mounted on these two bearings 12 directly to the mounting frame 2. In other words, it can also be stated that preferably two bearing points 12 are provided per axis A1.

The bearing 12 preferably comprises a bearing element 14, 31 and a receiving element 13. The bearing element 14, 31 is formed in the receiving element 13 hooked. In the suspended state, the bearing element 14, 31 engages or protrudes into the receiving element 13, whereby the connection between the bearing element 14, 31 and receiving element 13 is provided. For this engagement bearing element 14, 31 and receiving element 13 are at least partially matching or complementary to each other.

The bearing element 14 may be formed sprung with a spring 17, as here the upper bearing element 14 in the FIG. 3 , or the bearing member 14 may be formed as a rigid bearing member 31, as the lower bearing member 31st

The bearing element 14, 31 is preferably a pin 14, 31, which can be spoken by a spring-loaded bearing pin 14 in the case of the presence of the spring 17 and a rigid bearing pin 31. By the spring, the operation button 3 can be easily hooked into the receptacles 13.

With reference to the FIG. 7 Now hanging the operation button 3 is explained on the mounting frame 2. In this case, the bearing pin 14 is pressed in a first step with the spring 17 in the corresponding receptacle 13 and the spring springs accordingly. In this case, the actuating button 3 can be pivoted in the direction of mounting frame 2 and also with respect to the corresponding receptacle 13 are positioned. If the installer then releases the actuating button 3, then the spring 17 and the rigid spring relax Journal 31 automatically engages in the corresponding receptacle 13 and is stored in these recordings. Thus, the installer can very easily hang the operating button 3 on the mounting frame 2.

In the present embodiment, the bearing 12 on the mounting frame 2 in the shape of receptacles 13 and the bearing 12 on the actuating button 3 have the shape of bearing pins 14, 31. The bearing pins 14 protrude into the receptacles 13 and are stored there by the receptacles 13 accordingly. In alternative embodiments, the bearing 12 on the actuating button 3 but also have the shape of receptacles 13 and then the bearing 12 is formed on the mounting frame 2 as a bearing pin 14, 31.

The bearing pin 14 extends along an axis M. Likewise, portions of the receptacles 13 also extend along a corresponding axis M. The axes M extend parallel to said plane 10. The actuating button 3 is pivotable about this axis M. The axis M is substantially the axis A1 or A2, as already explained above.

Depending on the material, the bearing pins 14 are formed directly on the actuating button 3. The actuating button 3 can be injected, for example, from a plastic. Alternatively, for example, when the operation button 3 is made of glass or other material than plastic, the journals 14 may be parts of a frame 23. The frame 23 is connected via the rear surface 22 of the actuating button 3 with the actuating button 3 in connection. In such an embodiment, the actuating button 3 comprises essentially two parts, namely the actuating button 3 itself and the frame 23 which is materially connected to the actuating button 3. The frame 23 is preferably glued to the rear surface 22, whereby a material-locking connection between frame 23 and actuating button 3 can be provided. Although here is the operation button 3 on the frame 23 with the mounting frame 2 in conjunction, it can be said that the actuating button 3 is directly connected to the mounting frame 2 in connection, because of the said cohesive connection actuating button 3 and frame 23 are to be regarded as integral ,

A bearing 12 preferably consists of a pair comprising a bearing pin 14, 31 and receptacle 13. The pairings are spaced apart from each other. In each case two pairs are arranged on a common center axis M, wherein the two bearing pins 14 and the two receptacles 13 run collinear.

Of the FIG. 4 can be seen that the receptacle 13 with respect to the direction of movement of the actuating button 3 from the starting position into the flushing position as a channel 15, here as an open channel 15, is formed. The channel 15 is thus formed in a direction perpendicular to the plane 10 seen from the actuating button 3 in the direction of mounting frame 2 open. Consequently, the bearing pin 14 can be moved in the direction of movement with respect to the fixed receptacle 13. Upon actuation of the actuating button 3, the bearing pin 14 can be moved through this open channel 15.

The channel 15 is designed to be closed to the actuating button 3, for which purpose the channel 15 has a wall 16. The wall 16 provides a stop for the bearing pin 14. The stop thus ensures that the actuating button 3 can not be moved from the starting position against the usual movement in the flushing position. The wall 16 essentially has a stop section 24, from which two wall sections 25 extend. The two wall sections 25 then preferably run parallel or at an angle or inclined to one another. In the latter case, the cross section of the open channel 15 increases in the direction from the starting position in the scavenging position.

The angled design has the advantage that in this way the pivoting of the actuating button 3 is made possible.

Based on FIGS. 5a to 5c Now, the situation in the operation of the operation button 3 according to the first embodiment will be explained. In both FIGS. 5a and 5b is the operation button in the starting position and in the FIG. 5c shown in the end position. Upon actuation, here on the right area 6 of the actuating button 3, the actuating button 3 pivots about the axis A1, which extends perpendicular to the drawing surface here. When pressed on the left area 7, the operation button 3 pivots to the other side.

In this operation, the bearing elements 14, 31 preferably remain in the corresponding receptacle 13. Under great effort but it can still come to a movement in the direction of the channel 15 of the receptacle 13, which has the advantage that so undesirable forces can be compensated.

The movement can be guided by means of guide elements 33 which protrude into guide openings 34. The guide elements 33 are pins 33 projecting from the actuating button 3, which project into the guide openings 34 in the mounting frame 2. Guide elements 33 and guide openings 34 are also in the Figures 3 and 4 recognizable.

Based on FIGS. 6a to 6c Now, the situation when the operation button 3 according to the second embodiment is operated will be explained. In both Figures 6a and 6b is the operation button in the starting position and in the FIG. 6c shown in the end position. In the second embodiment, the guide elements 33 each have a stop element 32 at their ends. This stop element 32 acts on the back 35 of the mounting frame 2, so that a stop against movement from the starting position to the front, ie against the direction of normal operation towards the end position, is provided.

Next, the stop member 32 at the same time the pivot axis A2 ready, about which the actuating button 3 pivots to the mounting frame 2. During the pivoting in this embodiment, the bearing element 14 is moved out of the recess 13 in the direction of the channel 15. With a pressure on the left region 5 or the right region 6, therefore, the bearing element 14 is moved out of the recess. At a pressure on the right-hand area 6, the stop elements 32 arranged on the left are in contact with the rear side 35 of the mounting frame 2, and at a pressure on the left area 5 the stop elements 32 arranged on the right are in contact with the rear side 35 of the mounting frame 2 ,

Consequently, the stop element 32 and the back 35 serve as a pivot bearing or pivot about which the actuating button is pivoted.

In both embodiments, the actuating button 3 can be pivoted so far until the actuating button 3 is present with the surface 11 on the wall 9 or the mounting frame 2. With the actuating button 3, the actuator element 4 is then actuated and the flushing is triggered.

Next can of the FIG. 4 be recognized that the actuator 1 additionally has an optional operating lever 19. This actuating lever 19 acts here on the actuator element 4 with a projection 20. When the actuating button 3 is actuated, it acts on the actuating lever 19, which is then correspondingly pivoted and strikes the actuator element 4. In the presence of this operating lever 19, the return element preferably acts on this actuating lever 19 on the actuating button 3. The actuating lever 19 is pivotally mounted in two mounting points 21 in the mounting frame 3. If now the optional actuating lever 19 is arranged between the actuator element 4 and the actuating button 3, then the surface 11 of the actuating button 3 acts on the actuating lever 19, which is then pivoted about the corresponding bearing point 21. The actuating lever 19 then acts with its projection 20 on the actuator element 4, whereby the flushing is triggered.

The provision of the actuating button 3 from the flushing position to the starting position is then via the return elements 18. From the FIG. 4 can be seen that a return element 18, is arranged here in the shape of a plurality of leaf springs 18 between the mounting frame 2 and the actuating button 3. The return elements 18 act on the rear surface 22 of the actuating button 3 and are connected via the rear wall 28 with the mounting frame 2 in connection.

The return element 18 provides a restoring force to the actuating button 3 ready. Thus, the operation key 3 is moved out of the scavenging position to the home position. In the initial position, the actuating button 3 then rests in accordance with the bearing point 12th

The actuator element 4 preferably has the shape of a pneumatic pressure transducer in the present embodiment. In this case, a pressure pulse is generated by the pneumatic pressure transducer, which acts on a Spülventilanordnung. A pressure hose can then be passed through the openings 30 in the cistern. With regard to the actuator element 4, it should also be noted that the actuator element 4 is arranged between the actuating button 3 and the mounting frame 2. The actuator element 4 is particularly preferably connected to the mounting frame 2 or is mounted in the mounting frame 2.

In summary, the actuator 1 has the advantage that a very simple manufacture and assembly of the actuator 1 is allowed. In addition, aesthetic requirements can also be taken into account. Further, the actuator 1 is safer in use because it can not come to a snag between the operation keys and a frame.
