DESCRIPTION

Activation device for an outlet fitting of a cistern, cistern with an activation device of this type as well as a procedure for mounting an activation device in a cistern

The invention relates to an activation device according to the preamble of claim 1.

Document DE-U-295 10 495 publishes an activation device of the type indicated at the beginning. To fix it in the tank, a fixing screw is provided, which is screwed into a screw fixing unit of a washing mechanism.

EP-A-0 209 478 publishes an activation device with a push button housing, which can be placed for activation on a retaining ring, which is arranged on the bottom side of the tank lid and penetrates into the inside of a hole in the tank lid.

Document FR-2 819 835 publishes an activation device, which has a push button housing, which has a threaded appendix that projects downwards, which is screwed for fixing the push button housing on a yoke of the mechanism washed.

Document US-B-6,425,145 publishes a push button with integrated membrane valve, which has a housing, which is supported on the inner side with a flange, for example in a tank cover.

Another activation device is known in the state of the art from EP-A-1 995 386. In this device, the push button housing is fixed with a nut on a tank cover. The nut is screwed onto a part of the push button housing that projects on the bottom side of the tank cover and rests in the state mounted on the bottom side of the tank cover. The activation device can be raised with the tank cover from the outlet taps. Another activation device is also known from EP-A-0 479 714 of the applicant. In this device, the push button housing is fixed in the same way by means of a nut in a hole in a tank cover. This activation device can also be lifted with the tank cover from the outlet taps. The two activation devices mentioned are especially suitable for ceramic tanks.

The invention has the task of creating an activation device of the aforementioned type, which can be mounted even more easily.

The task is solved according to claim 1. In the activation device according to the invention, the fixing member is thus inserted together with the housing in the hole of the tank. In this way, the subsequent placement of a fixing nut is not necessary. The fixing element and the push button housing can be configured as a unit and can be inserted into said hole. The push button housing is fixed through the fixing member automatically through tension fixing on the wall in the tank wall. For fixing the push button housing, it only has to be inserted from above into said hole. It is not necessary to screw up a nut. The assembly is simplified in this way essentially and can be done without a tool.

In addition, it is provided that the fixing member is movable in the push button housing. In this way it is especially possible to detach the fixing member again by means of displacement, so that the push button housing can be removed again out of the hole. For detachment, it is especially provided that the fixing member moves in the housing of downward push buttons. The movement is performed especially against a recovery force, for example against a spring element.

In addition, it is provided that the fixing member has at least one extendable arm or a spring leg, with which the push button housing can be attached in the hole of the tank housing. During insertion of the push button housing, this at least one extendable arm or spring arm is first deflected inwardly and then preferably flexibly elapses to the expanded position, in which the push button housing is Marched on the wall mentioned. Preferably, at least two extendable arms of this type are provided. Obviously more than three extendable arms of this type can be provided. These move during insertion of the push button housing first radially inwardly and then radially outward.

According to a development of the invention, it is provided that at least one push button rod is housed in the push button housing, which is movable for the activation of the washing with the push button down. This push button rod is housed in a limited way in the push button housing. At a lower end, this push button rod is engaged with the outlet tap. At the upper end, the push rod rests on the push button. Preferably, two pushrods of this type are housed in the push button housing. One of these push-button rods is used to activate a partial wash and the

Another push button rod is used to activate a total wash.

The at least one push rod is provided with rotating retaining means. These rotating retention means make it possible to fix the push button rod in an adjusted position through a rotation about its longitudinal axis. For release, the push rod can be turned in the direction of reverse rotation around its longitudinal axis. Such rotating retention means are known per se.

According to a development of the invention, it is provided that the push button housing is essentially shaped in the form of a bowl and a flange that projects outwardly is present on a top edge, which can be tensioned with the fixing member against one side exterior of said cistern wall. This allows a particularly suitable fixation of the push button housing in said hole. The push button is pressed against said outer side through the fixing force of the fixing member. The push button housing remains fixed in this way.

The invention also relates to a cistern with an activation device of this type. The activation device is specially mounted on a tank lid. The cistern is, for example, a ceramic cistern.

During assembly of the fixing device, the push button housing with the fixing member from above is inserted into the hole of the tank housing and fixed with the fixing member in this hole. The push button housing is inserted in this way together with the fixing member from above in the hole. The fixing member fixes the push button housing in said hole. After fixing the push button housing, the at least one push rod is preferably adjusted with respect to the outlet taps. Preferably, in this case, a stop element is arranged in the at least one push button rod, which moves with the push button rod down and is positioned at an upper end of the outlet tap. This enables an especially precise adjustment of the at least one push rod. If the position of the push button rod has been adjusted, then it is preferably fixed by means of a rotating retention movement. This fixation could be easily detached if necessary and the push button rod could be adjusted again.

Other advantageous features are deduced from the patent dependent claims, the following description as well as the drawing. An exemplary embodiment of the invention is explained in detail below with the help of the drawing. In this case:

Figure 1 shows a section through an upper part of a tank, in which the push button housing is inserted together with two push button rods into a hole in the tank.

Figure 2 shows a section according to figure 1, in which the two push-button bars are positioned fully.

Figure 3 shows a section according to Figure 1, in which the two push-button bars are fixed in the adjusted position.

Figure 4 shows a section according to Figure 1, in which the fixing device is fully assembled.

Figure 5 shows a section according to Figure 1, in which the push button of the activation device has been moved for the wash down activation, and

Figures 6 to 10 show schematically the individual steps during fixing the push button housing in a cistern hole.

The tank 1 shown only partially in Figure 1 has a tank housing 4 and a cover 45. The wall 12 of the cover 45 has a hole 11 for example round circular, in which a fixing device 2 is inserted. The fixing device 2 has not yet inserted the push-button 37 shown in Figure 4. Inside the tank housing 4 there is a known outlet fitting 3, which has an outlet valve not shown at a lower end, which can be opened with the activation device 2 for a wash activation. The washing water that exists in an interior space 5 of the tank housing 4 is discharged in this way, for example, in a toilet bowl not shown here. The outlet faucet 3 is configured in such a way that optional a partial wash or a full wash is possible. Correspondingly, the activation device has a first push rod 14 and a second push rod 15. The first push rod 14 collaborates with a first slide 7 and the second push rod 15 collaborates with a second slide 8 of the outlet faucet 3. These slides 7 and 8 are housed in a faucet piece 6 and can be moved against the recovery force of a spring 9 down. A lever 10 is provided for opening the valve. The push button 37 correspondingly has a first piece of push buttons 38 and a second piece of push buttons 39. If only the first piece of push buttons 38 moves down, the first push button rod 14 is then moved correspondingly for the activation of a partial wash down. If the second piece of push buttons 31 is moved down, then the first piece of push buttons 38 is dragged and the two push rod rods 14 and 15 are moved down

for the activation of a total wash. The activation device 2 can also be configured in such a way that only a total wash is possible. Correspondingly, an activation device of this type 2 has only one push rod.

The activation device 2 has a push button housing 13, in which a fixing member 18 is housed. With this fixing element 18, the push button housing 13 can be fixed in the hole 11. This is explained in detail to then with the help of figures 6 to 10. The push button housing 13 and the fixing member 18 are shown schematically here for simple understanding.

As shown in Figure 6, the roof housing 13 has a flange 21 projecting outwards at an upper edge. From this, a lateral wall 22, for example cylindrical, projects downwards. The side wall 22 has side holes 23 and is integrally formed in a bottom 27, in which a fixing member 18 is movably housed. To this end, the fixing member 18 has a guide piece 31 projecting towards below, which penetrates through a hole 32 of a bottom 27. A spring element 26 is arranged between the bottom 27 and a wall 30. The retaining projections 33 at the lower end of the guide piece 31 prevents the organ of fixing 18 can be raised above the position shown in figure 6. The fixing member 18 has two opposite spring legs 24, which project in the position according to figure 6 laterally through the holes 23 beyond the housing of push buttons 13.

To tie the push button housing 13 into the hole 11, it is inserted together with the fixing member 18 according to figure 6 in the direction of the arrow 25 in the hole 11. The two legs of the spring 24 are deflected in this case. according to figure 7 in a flexible elastic way inwards. The push button housing 13 is inserted according to figure 7 into the hole 11 to the point that the tab 21 rests on an outer side 19 of the wall 12 of the tank 1. To tie the push button housing 18 into the hole 11, the fixing member 18 is now moved in a button 36 against the recovery force of the spring element 26 downwards. The two arms of the spring 24 are also correspondingly moved downwards and thus leave the hole 11, so that they can finally be expanded in accordance with Figure 8 and can reach the expanded starting position. The arms of the expanded spring 24 are thus totally below the wall 12. The push button housing 13 cannot now be lifted out of the hole 11, since the two arms of the spring 24 rest on the lower side 20 Through the tension of the spring element 26, the legs of the spring 24 are tensioned against the lower side 20. Correspondingly, the flange 21 is pressed on the outer side.

19.

From the position shown in Fig. 8, the fastener 18 can be moved in the pushbutton 36 further down until the wall 39 rests on the bottom 27. During this movement, the two legs of the spring 24 move through a stop in the side wall 22 radially inward. At the same time, the fixing member 18 is tied in a retaining part 28 of the bottom 27. The retaining part 28 penetrates in this case in the hole 29 of the wall 30. Since the two legs of the spring 24 are articulated towards inside, the push button housing 13 according to figure 10 can be removed in the direction of the arrow 34 out of the hole 11. Through the release of the retention piece 28, the fixing member 18 can be brought back to the starting position shown in figure 6. The push button housing 13 can be mounted again.

The push button housing 13 shown in Figure 1 has been assembled in accordance with Figures 6 to 8. The two pushbutton bars 14 and 15, which have been omitted in Figures 6 to 10 for reasons of the drawing, must be positioned. now with respect to the outlet faucet 3. In this case, the push-rod rods are movably housed in a slide 41. For the housing two guide pieces 42 and 43 are provided. The first guide piece 42 receives the first push button rod 14 and the second guide piece 43 receives the second push rod 15. These guide pieces 42 and 43 are housed vertically in the slide 41. For the regulation of the push rod 14 and 15, these they are rotated around its longitudinal axis, so that they fit with the guide piece 42 and 43, respectively, and move in each case in the longitudinal direction downwards to the position shown in figure 2. Some stop elements 16 di The positions on the pushbutton bars 14 and 15 move in this case in the same way downwards. The desired position is achieved as soon as these stop elements 16 rest on the faucet part 6. The two push-button rods 14 and 15 are rotated in each case around their longitudinal axis, for example around 90 °, so which are tied with the first guide piece 42 or with the second guide piece 43. The two stop elements 16 are articulated in the same way and no longer form any stop in the articulated position. The two pushrod rods 14 and 15 are now positioned exactly with respect to the outlet faucet 3 or with respect to the two slides 7 and

8. These positions are shown in Figure 3.

The push button pieces 38 and 39 are then placed on the two push button rods 14 and 15 or inserted into the push button housing 13. Through the pressing of the two push button pieces 38 and 39 or a wash can be activated from the first piece of push buttons 38. The push button 37 is projected as clearly shown on the outer side 19 of the tank housing 4. However, this is not mandatory. The push button 37 could also be flush with respect to the outer side 10

or with respect to a screen 44 of the push button housing. Screen 44 is set as
