BACKGROUND OF THE INVENTION

Upper which

From the German utility model according to DE 23 16 824 U1, such an actuating device is known with a body and a movably arranged push-button therein for actuating the flush tank drain fitting. The body is formed in two parts and has an outer body part with a flange or frame abutting the upper wall of the flush tank lid, the body portion further having a substantially cylindrical body, extending through an opening in the flush tank lid into its interior. Inside the flush tank there is also a lower part with a pot-shaped body, the internal thread of which is screwed onto the external thread of the cylindrical extension of the upper part. The lower body of the button or knob has bearings and fasteners for the control lever and further has fasteners for an adjustment sleeve in which the adjustment rod is slidably mounted. The construction and assembly of such a device is very costly, since said adjusting sleeve must be connected to the bottom and the control bar must be hung, service or repair is required, thus starting is not possible without risking damaging the flushing tank lid. the control device and / or the entire drainage fitting.

Furthermore, the flush tank outlet valve control device is also known from the German utility model according to DE 91 10 092 U1, which also has a two-part button body. The upper part disposed substantially on the upper side of the flush tank lid has a guide sleeve which extends through the opening of the flush tank lid into its interior and is provided with an external thread. In the direction from the inside, a threaded nut is screwed onto the outer thread of the guide sleeve, whereby the upper part is fixed to the flush tank lid. A substantially cylindrical rod is connected to the trigger button and extends through said threaded sleeve. The upper part of the button body protrudes at a relatively large distance over the outer surface of the flush tank lid and is exposed to the risk of damage. The opening which is provided in the flush tank lid for the threaded sleeve of the button body has a relatively small diameter and an enlargement of the body projecting inwardly or of the guide sleeve is not entirely possible with respect to the thread connection.

Finally, a control device is known from the German utility model according to DE 92 10 440 U1, the control button of which is actuated within the flush tank by levers which are connected to the valve body of the drain valve. During assembly, it is necessary to make a positive connection between the control button and the drain valve lever, and to carry out service or repairs, it is necessary to disassemble this connection between the control button and the levers. The flushing tank lid is mounted on top of the flushing tank body, which is filled with water in a known manner. The flush tank is designed for wall mounting and the lid with control button is freely accessible from above. The control device cannot be used in flush cisterns. For concealed installation, the above-mentioned, customized design of the control device is necessary, which makes the corresponding production and storage costs conditional.

SUMMARY OF THE INVENTION

Starting from the foregoing, the invention aims to further develop a control device in the sense that simple assembly or disassembly is possible with a simple design. The control device should be used without any problems for both wall-mounted cisterns and flush-mounted cisterns. Furthermore, expensive connecting means between the control button and the drain fitting are to be omitted.

The task solution is carried out according to the features set forth in the feature of claim 1.

The designed control device has a functionally safe construction and allows universal use both for the installation of wall-mounted cisterns and flush-mounted cisterns. The control button, preferably two control buttons, is housed in a body formed as a replaceable body and forms a prefabricated assembly therewith. The replaceable body with at least one operating button is arranged in the lid clamping element and protrudes into the interior of the flush tank or lid. The clamping element has an extension, preferably directed towards the inside of said interior space, which is at least partly formed circular. The extension has a depth which is a predetermined factor greater than the thickness of the lid wall in the region of its opening. The clamping element and / or the extension extend from the inner surface of the lid at a predetermined depth to the inner space surrounded by the lid. Thus, the size of the inner surface of the clamping element may be predetermined in accordance with the requirements so that the replaceable body abuts with its positive fit outer surface and / or substantially tightly on the inner surface. The connection between the replaceable body and the flushing tank lid, in particular its clamping element, is preferably formed in a positive fit. Furthermore, the replaceable body is preferably inserted into the clamping element of the flushing tank lid in a manner of stationary connection, the abutting surfaces of the replaceable body and the clamping element being mutually aligned with each other. The replaceable body and / or the clamping element are preferably made of plastic and, given the elasticity of the plastic, a problem-free, stationary fit is predetermined.

The replaceable body preferably has a stop, in particular in the form of a flange arranged in the region of the outer surface of the lid, in order to ensure a defined alignment of the replaceable body after insertion into the lid. The surface of the removable body, visible from the outside, is further arranged substantially so as to coincide with the outer surface of the lid. The same applies to the surface of at least one button. The replaceable body with at least one operating button must be pushed only into the clamping element as an easily replaceable module and can be removed again in the opposite direction if necessary without carrying out all the maintenance measures. Although the force connection of the replaceable body with the clamping element and / or the flushing tank lid has proved to be the least suitable, the form-fitting connection, for example with clamping elements and / or stop elements, is also within the scope of the invention.

The at least one actuating button is mounted in a linearly movable manner in a replaceable manner, and the replaceable body has a guide means for guiding the actuating button and / or the trigger element in a linear manner connected to the actuating button. The trigger element, which is preferably designed as a pin, is connected in particular to the positive connection with the connecting part, the connecting part itself being arranged and housed in the flush tank. When actuating the actuating button, the actuating element acts only by a force connection on the coupling part by means of which the drain valve is opened or closed. For example, the connector may be formed as a flushing tank on a bridge, bracket or similar pivoted lever, in particular supported by the free end of the actuating element or the pivot, and which is pivoted to open or close the drain valve. During installation, only the flushing tank lid must be fitted to the flushing tank or otherwise connected to it, at the same time at least one operating button being connected to the connecting piece. It is not necessary to suspend or establish another connection of the control button to the associated elements of the cistern. According to the invention, the actuating device formed as a separate module can be arranged for flushing tanks of different construction, with reference in particular to wall-mounted flushing cisterns and flush-mounted cisterns.

Further embodiments and particular embodiments of the invention are set forth in the subclaims and are further explained in the description below in an exemplary embodiment.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows in cross-section the cover 2 of the flushing tank with the wall thickness 3 with the clamping element 4, which is preferably formed as an annular extension 5 facing the interior space of the lid 2. The extension 5 does not have to run circumferentially the clamping element 4 serves to clamp the replaceable body 6 in the opening 7 of the flush tank lid 2, the opening 7 being closed from the side or limited by the clamping element 4. As will be explained further below, the flush tank cover 2 together with the replaceable body 6 can be arranged in a vertical or horizontal position, i.e. rotatable by 90 [deg.] in accordance with FIG. The clamping element 4 has an inner surface 8 and protrudes to a depth 9 above the inner surface 10 of the lid 2 into the interior 11. With the inner surface 8 of the clamping element 4 the outer surface 12 of the interchangeable body 6 is aligned so that the interchangeable body 6 can be inserted into the clamping element 4 and clamp firmly. The clamping element 4 is arranged on the edge 13 of the opening 7 of the lid 2 and protrudes from the edge 13 into the interior 11. The flush tank lid 2 and / or the replaceable body are preferably made of plastic which ensures spring and elastic insertion and fit For example, if the surfaces 8 and 12 are cylindrical, the inner diameter of the inner surface 8 is a predetermined value smaller than the outer diameter of the outer surface 12 of the exchangeable body 6.

For mounting, the replaceable body 6 is pushed in the direction of the arrow 14 with sufficient pressure into the clamping element 4 and thus into the interior 11 without the need for further fastening measures, such as a fixed screwing on the inside. The removable body 6 is pulled out against the direction of the arrow 14, whereby only the corresponding force must be exerted and special tools are as little necessary as loosening additional screws, fasteners or the like.

In order to guarantee a defined position of the replaceable body 6 in the flush tank lid 2, the replaceable body 6 has a stop 15, which is preferably designed as a small annular flange. The stop or flange 15 engages in a preferably annular opening 16 in the lid 2 of the flush tank. The stop 15 and the associated aperture 16 are preferably formed such that the outer surface 17 of the replaceable body 6 is substantially flush with the outer surface of the flush tank lid 2. For correct positioning of the replaceable body 6, this small nose 19 has an engagement with the corresponding groove 20 of the clamping element 4 or the flush tank lid 2. As can be seen, the depths of the openings 16 on the flange 15 coincide. Irrespective of the particular embodiment, the clamping element 4 and / or the flushing tank lid 2 has a stop surface for precisely positioning the replaceable body 6, according to FIG. 16 for the associated sleeve 15.

In the removable body 6 there are two control buttons 21, 22 for starting or interrupting the flushing. The two control buttons 21, 22 are linearly displaceable in the direction of the arrow 14 in the removable body 6 by means of a manual control, if necessary. The buttons 21 are now, although preferably in one piece, connected to the trigger element 24, 26, which are preferably designed as pins and are hereinafter referred to as. The replaceable body 6 has axial guide means 28, 30 for the pins 24, 26 in the bottom 32. The caps 24, 26 preferably have not a cylindrical cross section but a polygon cross section and an inner cross section.

28, 30, and finally, the control rotation. Triggering elements of the guide surface correspondingly. Thereby the pins 24, buttons 21, 22 secured against or pins 24, 26 protrude with their free ends across the bottom 32 into the space 11. The free ends of the pins 24, 26 are designed as locking elements 34, 36 so that the buttons

21, 22 together with the pins 24, 26 belonging thereto could be inserted into the replaceable body 6, with the locking elements 34, 36 slipping through the guide elements 28, 30. The free ends of the pins

24, 26 have at least one slot 38, 40 at least in the region of the locking elements 34, 36, which apparently allows the insertion of the locking elements by the axial guide elements 28 shown by the clamping elements in common 34, 36 when punching

If the pins 24, 26 are completely pushed in the manner, then the means, which are designed to be sufficiently flexible, assume their position again and make it possible to lock in place due to their increased diameter or the locking surface which is on their rear side. control buttons 21, 22 in the removable body 6.

Fig. 2 shows the control device in the assembled state according to which the replaceable body 6 is designed as a module anchored in the clamping element 4 of the flush tank cover 2. The outer surface 17 of the removable body 6, visible from the outside, is substantially flush with the outer surface 18 of the cover 2 of the removable body 6. When the push buttons 21, 22 are in position 0 of FIG. with external surface .18. cover 2 of the cistern. To start the flushing operation, for example, the control button 21 is pressed into the position shown, whereby the functional parts, not shown here, located inside the flushing tank, are actuated. Schematically, for example, a connecting piece 43 in the form of a lever, which is mounted in a flush tank, is pivotable about an axis 44 perpendicular to the plane of the drawing. The pins 24, 26 are not connected to the positive connection with the connecting piece or lever 42, but the pins 24, 26 only engage the two-arm lever 43 with their free ends. One of the control buttons 21 is shown in a depressed state in which flushing is triggered. In this case, the second control button 22, which can be referred to as a stop button, is pushed out of the flush tank lid 2 in the reverse direction. If necessary, the flushing can be interrupted by operating the control button 22 or the stop button in the direction of the arrow 14.

The buttons 21, 22 have side faces 45, 46 that abut with sufficient clearance on the inner guide surface 47 of the replaceable body 6. As is apparent, the side faces 45, 46 are considerably large as well as the guide surface 47, thereby achieving a light weight. Therefore, there is no need to worry about damaging the above-described pins 24, 26 or actuators as well as their associated axial guides, even when the buttons 21, 22 are pushed or actuated strongly. The replaceable body 6 and the axially movable pushbuttons 21, 22 can be produced without difficulty with large surfaces and / or in accordance with the requirements, without having to comply with dimensional or shape constraints.

Fig. 3 shows in a perspective view and in an exploded state the flush tank cover 2 in a vertical arrangement in front of the flush tank 48, which is installed under plaster, on which the lining and / or tiles are formed in a known manner after assembly. The opening 49 can be closed by the flush tank lid 2, which can be lowered if necessary to reach components arranged inside the flush tank 48, such as an outlet fitting with a flushing tank. valve as well as inlet valve. In the region of the aperture 49, there is shown a connecting piece not shown in greater detail. On the front side of the flush tank lid 2, the two control buttons 21, 22 of the removable body 6 can be seen. The outer contour of the removable body 6 is oval in this embodiment, but within the invention it can have the removable body 6 like the control buttons 2i, 22. other shapes or sizes.

Fig. 4 shows another embodiment in which the flush tank cover 2 is arranged horizontally above the flush tank 48. A horizontal plate or shelf may be arranged between the flush tank cover 2 and the flush tank top 50 in a known manner, which are preferably tiled. The opening 49 of the flush tank 48 is located in the region of the horizontally arranged upper side 50 of the flush tank 48 and after removal of the wolf 2 of the flush tank 48, the interior of the flush tank is freely accessible.
