Abstract

The unit has an operation frame (6), which is at least partly accessible from outside the plaster and has two keys. The keys are independently operable and are coupled to an operation mechanism (10-14,16,19), to open and close a drain valve. A first, larger, key (9) opens the drain valve to flush a first, larger, water quantity. A second, smaller, key (8) either closes the drain valve or releases a second, smaller, water quantity. An Independent claim is included for a flushing device for flushing a toilet.

Description

The invention relates to an actuating device according to the preamble of the claim 1. Such actuators are especially for under plaster built-in cisterns used by toilet flushing, the actuating mechanism partially mounted on and in the cistern and the user only the sees the respective operating frame with the buttons.

Stop and Go" Mechanismus erwünscht ist, eine andere Steuerung bzw. Dosierung der Spülmenge kann mit dieser Betätigungsvorrichtung nicht erreicht werden.An actuating device for a drain fitting is known from EP 733 749 A1, which is arranged in a cistern. Via a first actuation button, a bolt can be moved, which is connected to a triggering device for starting the washing process. If the user wants to interrupt the flushing, a second button is connected to the trigger device via a further pin in order to close the drain valve on the cistern again. The actuating device shown can be used for drain fittings in which a

Stop and Go "mechanism is desired, a different control or dosage of the flush volume can not be achieved with this actuator.

Furthermore, it is known to have two buttons in an actuating device for cisterns to provide, both via an actuation mechanism, an opening of the drain valve can cause in the cistern. With the first button there is a full rinse with about 9 liters of water, while with the second button one Rinsing with a reduced amount of water (e.g. 3 liters). This arrangement is also called two sets of technology and has the advantage that the operator can easily save water without interrupting the rinsing process.

When installing a cistern with a known actuator must always be determined beforehand whether a two set technique or a stop and Go technology should be used because different actuation mechanisms for both technologies required are. This is because of the high storage costs for two different systems unsatisfactory. Also, confusion between the two can Techniques for installing the flushing system for expensive downtimes during assembly to care.

The invention is therefore based on the finding that the separate provision of actuators for different techniques is unsatisfactory and it is therefore an object of the invention to provide an actuating device which can be used for both the two sets of technology and the stop and go technology is.

This task is carried out with an actuating device, in particular for flush-mounting built-in cisterns detached from toilet flushing, with an operating frame, which is at least partially accessible from the outside and on which two buttons are provided, which can be actuated separately and with an actuating mechanism are coupled, with a drain valve by means of the actuating mechanism can be opened and closed and the first button the drain valve opens so that a first amount of water flows out of the cistern, whereby through the Pressing the second button either the drain valve can be closed or a second amount of water flows out of the cistern, which is smaller than the first amount of water is. This training enables the use of the actuator both with the two sets of technology and with the stop and go technology. The The fitter only has to bring an actuating device for installation, which can be adapted for both techniques. Downtime due to wrong Actuator is thus safely avoided. Furthermore, the storage costs reduced because no two actuators are separate from each other must be in stock.

In a preferred embodiment of the invention, the actuation mechanism adjustable to set the function of the second button. The adjustment can take place via a lever, a switch or a rotating mechanism changed the power transmission path or the direction of the power transmission path becomes. The operator can operate the actuation mechanism without major assembly processes set to the desired operation. If the two sets Technology is selected, the flow rate can also preferably the adjustment mechanism can be adjusted.

If the actuating mechanism has a replaceable component to the Setting the function of the second button is the actuator as a kind Kit prepared so that the fitter only by choosing the right one Component, for example the right lever or switch, the desired function the actuator can adjust.

A particularly simple and reliable actuation mechanism is obtained if this has a first slider which is connected to the first key and has a second slider connected to the second key, wherein both sliders on a lever for opening and closing the drain valve Act. The length of the slider can be easily adapted to the respective Installation situation to be adjusted, especially if the slide is formed in several parts are. Preferably, the first button and the first slider a linkage can be raised to open the drain valve, and to close the Drain valve by the second button, the second slide engages the lever, to move the lever against the direction of actuation. Alternatively, you can use the first button and the first slider or the second button and the second Slider a linkage to open the drain valve can be raised.

The first buttons and are independent of the setting of the actuating device the second key is held in its initial position by means of a spring, so that they automatically return to their starting position after actuation.

According to a preferred embodiment of the invention, the operating frame mountable on a substantially horizontal top of a cistern, so that it is easily accessible. Alternatively, the actuating frame on a essential vertical front of a cistern can be mounted. Preferably the actuator is designed so that it both on a horizontal surface as well as on a vertical surface, so that for both applications are provided only a single actuator got to.

According to the invention, a flushing device for flushing the toilet is also provided, with a cistern on which a water supply and a drain valve are provided, the flushing device being an actuating device according to the invention having.

The flushing device shown in FIGS. 1 to 4 comprises a cistern 1 Plastic that can be attached to a wall of a house using side flanges 2 can. The cistern 1 is surrounded by a housing 3. On the bottom the cistern 1, an outlet 4 is provided in a toilet, not shown flows. At drain 4, a drain valve is arranged, which by means of an actuating mechanism can be opened and closed. At the top of the Cistern 1 is a shaft 5, usually arranged under plaster, provided with an operating frame 6 with a large button 9 with one facing the toilet Front edge 7 and another small button 8 is closed.

The buttons 8 and 9 can be pivoted about an axis 100 in the actuating frame 6 stored. The key 8 is with a bolt 10 and the key 9 with a bolt 11 connected. The length of the bolts 10 and 11 can be like the length the shaft 5 to be adapted to the particular installation situation.

The bolt 10 is connected to a slide 12 made of plastic, which in one Attachment 17 is slidably mounted. The slider 12 is through upwards a spring 24 biased so that it automatically in its after an operation upper starting position returns. The slider 12 is integral with an operating arm 16 formed of a T-shaped end piece with a Has nose 23 and a driver 26.

The bolt 11 connected to the button 9 is in one at its lower end Slider 13 made of plastic. The slider 13 is integral with an L-shaped Arm 130 formed, on which a spring 25 rests, which the arm 130 with the slide 13 biases upwards. The spring 25 is about a pin 22 arranged and supported on a further pin 23 with a spring arm.

To actuate the drain valve, a lever 14 is provided which can be pivoted is mounted about an axis 15. The lever 14 is at its lower end with a Rod 19 connected to retaining ribs 20 on which an actuator 21 for Drain valve is attached.

As shown in FIG. 5, the flushing operation is carried out by pressing the large button 9 initiated. As a result, the bolt 11 is downward against the force of the spring 25 pressed, the slider 13 being displaced with the arm 130. The arm 130 presses on the right of the axis 15 from the lever 14, so that the left part of the lever 14 is moved with the rod 19 upwards. This will the actuator 21 is raised so that the drain valve is opened.

To cancel the rinsing process before the full rinse is complete, according to FIG. 6 the small button 8 pressed so that the bolt 10 together with the slide 12th is moved down. At the same time, the actuating arm 16 of the slide presses 12 over the driver 26 to the left part of the axis 15 seen from the Lever 14 so that the lever 14 is pivoted and the rod 19 together with the actuator 21 is moved down. This will make the drain valve closed again.

If the user uses the Stop and Go technique for flushing described above does not want to use the actuation mechanism on the two sets Technology changed. For this purpose, the slide 12 is a modified slide 12 'replaced (Fig. 7-9).

The slider 12 'is coupled to a lever 16' which has an edge 27 which cooperates with a drop-shaped projection 28 on the lever 14. At a Movement of the lever 16 'slides the projection 28 over the edge 27, so that the lever 14 is also pivoted.

A full flush is obtained by pressing the large button 9 (Fig. 8). there is about the bolt 11, the slider 13, the driver 26, the lever 14, the Rod 19 and the actuator 21 opened the drain valve. Through the Force of the spring 25 and the gravity acting on the components mentioned the drain valve automatically closes again after full flushing when the the desired amount of water has flowed through the drain valve.

If the user only rinses with a reduced amount of water wants, must be pressed on the small button 8 (Fig. 9). This will remove the bolt 10 moved down with the slider 12 '. The slide 12 'presses the lever 16 'which is pivoted about the axis 22 so that the edge 27 is turned upwards and rotates the lever 14 over the projection 28. This will make the actuator 21 raised above the rod 19 and the drain valve opened. In order to the flushing process is shorter than with full flushing, the spring 24 presses on the Lever 16 ', so that an opposite movement over the edge 27 and the projection 28 the lever 14 is promoted. Depending on the strength of the spring force, the Drain a larger or smaller amount of water through the drain valve.

10 to 13 is a further embodiment of an inventive Actuating device shown on a cistern 1 'with a vertically installed Operating frame 6 is provided. The cistern 1 'is like that previous embodiment surrounded by a housing 3 and over Side flanges 2 attachable to a wall.

Despite the horizontally aligned arrangement of the actuating frame 6 and the Shaft 5, the actuation mechanism for the flushing is essentially the same the actuating mechanism described above, with the same reference numerals were used for essentially identical components.

In Fig. 12 the actuation mechanism is equipped for the two quantities of operation. For this purpose, the slide 12 'is movable via the button 8 and the bolt 10, which the Can pivot lever 16 '. An edge 27 'is formed on the lever 16' engages the projection 28 'and can thereby pivot the lever 14'. The Lever 14 'and the rod 19' are shaped differently in this embodiment than the lever 14 and the rod 19, but the function is identical. By actuation of the button 8 can accelerate the rod 19 'again via a spring force can be moved down to make the passage valve faster during the partial flushing to close. The button 9 is pressed in the same way for a full flush as in the previous embodiment.

In Fig. 13 the actuation mechanism for the stop and go technology is converted. For this purpose, a driver of the slide 16 engages the lever 14 'in order to remove it in the raised position and end the rinsing process. The movement of the slider 16 is in this case by pressing the button 8 and Forced movement of the pin 10. The button 9 directs the rinsing process over the Bolt 11, a slider 13, the lever 14 'and the rod 19'.

In the illustrated embodiments, the changeover from two quantities Technology on stop and go operation and vice versa by changing one Slider 12 and 12 'and the actuating arm 16 and the lever 16' reached. Alternatively it is possible for the slide 12 and the actuating arm 16 not to be integral train, but put together by means of snap connections, so that a change by simply changing the edge 27 'and the driver 26 can. Furthermore, the changeover can be implemented by other known mechanisms, for example using levers, switches or knobs.
