Description

Technical field

The invention relates to a control device for a flush tank drain fitting according to the features of the preamble of claim 1.

BACKGROUND OF THE INVENTION

A German utility model according to DE 23 16 824 U1 discloses such a control device 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 top wall of the flush tank lid. Furthermore, the upper part of the body has a substantially cylindrical body which extends through an opening in the lid of the flushing tank into its interior. Inside the flushing tank there is also a lower part with a pot-shaped body whose internal thread is screwed onto the external thread of the cylindrical extension of the upper part. The lower body of the button or cartridge 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 manufacture and assembly of such a device is very costly, since said adjusting sleeve must be connected to the bottom and the control rod must be suspended. If service or repair is required, disassembly is not possible without the risk of damaging the control device and / or the entire drain fitting when putting the flush tank lid down.

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 button body formed in two parts. The upper part arranged 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 arranged in the flush tank lid on the threaded sleeve of the button body, has a relatively small diameter and an enlargement of the part of the protruding body or 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. When assembling, it is necessary to make a connection with the positive connection between the control button and the lever of the drain fitting and to carry out service or repairs it is necessary to disassemble this connection between the control button and the levers. The flush tank cover is mounted above the flush 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 flush-mounted installation, the above-mentioned adapted design of the control device is necessary, which results in a corresponding production and storage cost.

SUMMARY OF THE INVENTION

Starting from the foregoing, the invention has as its principal object the further development of a control device in the sense that simple assembly or dismantling is possible in a simple design. The control device should be used without any problems both for wall-mounted cisterns and flush-mounted cisterns. Furthermore, expensive connecting means between the control button and the drain fitting are to be omitted.

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

The designed control device has a functionally safe design 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. A 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 inwardly of said interior space, which is at least partly designed as a circular. Said 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 with 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 configured with an interference fit. 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, 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 flush 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, without necessity, to carry out maintenance measures if necessary. Although the force connection of the replaceable body with the clamping element and / or the flushing tank lid has proven to be the least suitable, it is within the scope of the invention to include a form-fitting connection, for example with clamp elements and / or stop elements.

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 actuating element in a linear manner 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 control button, the actuating element acts only by a force connection on the connecting part, by means of which the valve is

SK 281365 Β6 flow valve, opens or closes. For example, the coupling part can be formed as a flushing tank on a bridge, bracket or similar pivotally mounted lever, in particular a free end of the actuating element or pin, and which, when the actuating button is pushed, 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 hang up 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.

Other 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.

Overview of the figures in the drawing

The invention is explained in more detail below by way of example of embodiment shown in the drawings. Fig. show:

Fig. 1 shows a sectional view of an exploded control device with a flush tank lid, FIG. 2 shows the control device of FIG. 1 in an assembled state, FIG. Fig. 3 shows the flush tank cover arranged for vertical mounting together with a flush-mounted flush tank in an exploded state; 4 is a horizontally spaced flush tank cover.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows in cross-section the lid 2 of the flushing tank with a wall thickness 3 with a clamping element 4, which is preferably designed as an annular extension 5 facing the interior space of the lid 2. The extension 5 does not have to be circumferentially integral with the invention. or may be partially interrupted. The clamping element 4 serves for clamping the replaceable body 6 in the opening 7 of the flush tank cover 2, the opening 7 being closed sideways or limited by the clamping element 4. As will be explained below, the flush tank cover 2 together with the replaceable body 6 can be arranged in accordance with FIG. 1 in a vertical or horizontal position, i.e. rotating through 90 °. The clamping element 4 has an inner surface 3 and protrudes to a depth 9 above the inner surface 14 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 at 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 of plastic, which guarantees spring and elastic insertion and replaceable 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.

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 designed such that the outer surface 17 of the replaceable body 6 is substantially flush with the outer surface of the flush tank cover 2. For the 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 of 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 accurately positioning the replaceable body 6; 1, this stop surface is preferably designed as an opening 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, 22 are now, 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 of the wedge 32. The pins 24, 26 preferably do not have a cylindrical cross section, but the polygonal cross-section and the inner surfaces of the guide means 28, 30 are formed correspondingly. Thus, the pins 24, 26 and finally the control buttons 21, 22 are secured against rotation. Trigger elements or pins 24, 26 project with their free ends over the bottom 32 into the intermediate space 11. Free ends of the pins

24,26 are formed as locking elements 34, 36 so that the buttons 21, 22 together with the pins 24, 26 belonging thereto can be inserted into the replaceable body 6, the locking elements 34,36 being pushed over by 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 locking elements 34, 36 to be inserted together when the axial guides 28, 30 are inserted. The locking means, which are designed to be sufficiently resilient, then assume their position again and, by virtue of their increased diameter or the closing surface on their rear side, engage the control buttons 21, 22 in the removable body 6.

Fig. 2 shows the actuating 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. As long as the control buttons 21, 22 are in position 0 according to FIG. 1, their outwardly facing surfaces 41, 42 also substantially align with the outer surface 18 of the flush tank lid 2. To start flushing, for example, the control button 21 is pushed into the position shown, whereby the functional parts, not shown here, located inside the flushing tank, are brought into the

SK 281365 činnosti6 activities. Schematically, for example, a connecting piece 43 in the form of a lever is shown, which is mounted in a flushing tank 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 operating buttons 21 is shown in a depressed state in which flushing starts . In this case, the second control button 22, which can be referred to as a stop button, is pulled out of the flush tank lid 2 in the reverse direction. If necessary, 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 surfaces 45, 46 which abut with sufficient clearance on the inner guide surface 47 of the removable body 6. As can be seen, the side surfaces 45, 46 are considerably large as well as the guide surface 47, thereby making it easy control with low material costs. Therefore, even if the buttons 21, 22 are pressed or actuated strongly, there is no need to worry about damaging the explained pins 24, 26 or the actuators, as well as the associated axial guides. 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 a perspective view and an exploded view of the flush tank cover 2 in a vertical arrangement in front of the flush tank 48, which is installed under the plaster, on the front side of which a lining and / or tile is formed in a known manner. corresponds to the opening 49 at the upper end of the flush tank 48. 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 a drain valve with a valve such as and inlet valve. In the region of the aperture 49, there is shown a connecting piece (not shown). 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 21,22. other shapes or sizes.

Fig. 4 shows another embodiment in which the lid 2 of the flush tank 48 is arranged horizontally above the flush tank 48. Between the lid 2 of the flush tank 48 and the upper side 50 of the flush tank 48, a horizontal plate or shelf can be arranged in a known manner. The opening 49 of the flushing tank 48 is located in the region of the horizontally arranged upper side 50 of the flushing tank 48, and after removing the lid 2 of the flushing tank 48, the interior of the flushing tank is freely accessible.
