Definitions
- the present invention relates to a cistern with a lid.
- the cover and the actuating device are held by means of a threaded tube arranged on the drain valve.
- the threaded pipe must be cut to length on the commercially available cisterns of different dimensions, which is expensive.
- the actuation buttons arranged in the screw sleeve must also be adapted accordingly.
- a flushing mechanism for a toilet cistern which is set up to allow two different volumes of water to flow out of the previously filled cistern by acting on at least one actuation button.
- the mechanism is surrounded by the cistern and has an overflow pipe which is provided with a sealing valve at its lower end.
- the sealing valve and the associated mechanism are connected via two struts to an operating button which is arranged in a cover of the cistern.
- the struts used can be fixed at different intervals using locking devices.
- the mechanism can be tightened as a whole against the lid.
- the invention is based on the object of designing the actuating device in such a way that, in the case of cisterns with different dimensions, the cover is held securely in its covering position on the cistern with relatively simple means. It is part of the task to propose means with which the actuating device can be easily attached to different lids with different thicknesses.
- connection of the lid to the drain valve arranged at the bottom of the cistern can be considerably simplified, since an individual cut to length of a threaded pipe can be omitted.
- the struts are attached directly to the housing of the actuating device on opposite receptacles with a corresponding shaped piece, the opposite end regions the struts can be plugged into the receptacle on the drain valve by placing the lid on the cistern.
- the snap-in receptacles are designed so that they allow the struts to be pushed in but prevent them from being pulled out.
- a spring-elastic compensating element is arranged between the underside of the lid and the housing or the counterpart to adapt to different thickness covers of the cistern, so that the screwing depth of the screw sleeve into the housing remains the same regardless of the thickness of the lid, so that a special adjustment of actuating buttons of the actuating device is no longer required.
- the housing has a central housing, which is surrounded in a ring shape by an annular body, the annular body being connected to the central housing in an axially displaceable manner by means of two diametrically opposite leaf springs.
- resilient tongues being formed on the projections, which in the plug-in position surround corresponding recesses in the respective fitting and secure the strut in the plug-in position.
- resilient tongues are expediently formed on the end face of the ring body facing the cover, with which the difference in length between the individual latching steps of the struts for the cover of the cistern can be compensated.
- the individual struts are advantageously assembled from two parts, one part of the strut being formed on the drain valve, while the other part with the end opposite the shaped piece can be inserted into a sleeve formed on the strut attached to the drain valve.
- the sleeve has a resilient tongue which interacts with a toothing on the other part of the strut, in such a way that the end region opposite the shaped piece can be inserted into a sleeve and can be locked in steps with the resilient tongue.
- a sawtooth-like toothing can expediently be used, which allows insertion of one part of the strut into the sleeve of the other part of the strut but prevents it from being pulled out.
- the ring body with the resilient tongues, the leaf springs and the central housing is advantageously made in one piece from plastic.
- a cistern 1 is shown, in the bottom 11 of which a drain valve 2 is fastened in an opening.
- a flushing line (not shown in the drawing) for a toilet can be connected to a connecting piece 21 of the drain valve 2.
- the cistern 1 is filled with rinse water to a certain level by a float-controlled inlet valve, not shown in the drawing.
- the cistern 1 is closed with a lid 10.
- a screw sleeve 31 is arranged on the outside of the cover 10 and penetrates an opening in the cover 10 with a tubular pin and is screwed to a screw socket of a housing 30 of an actuating device 3.
- the screw sleeve 31 is screwed onto the housing 30 as far as it will go, the different wall thicknesses in the commercially available cisterns being compensated for with a resilient molded body 6 made of foam rubber.
- a button 32 which is accessible from outside for pressure actuation.
- a fluid for example air or water
- a valve lifter (not shown in the drawing) on the drain valve 2, so that it is moved into an open position and the flushing water present in the cistern 1 is released for the toilet flushing.
- a strut 4a, 4b Diametrically opposite, two receptacles 33 are formed in the housing 30, into each of which a strut 4a, 4b can be inserted with a shaped piece 40a.
- Each of the two struts 4a, 4b is provided after the shaped piece 40a with leaf spring-like bends 44, which are followed by a straight end piece which can be inserted and locked into a snap-in receptacle 20 on the drain valve 2.
- the leaf spring-like bends 44 With the help of the leaf spring-like bends 44, the step-like latching caused, for example, by a toothing on the struts 4a, 4b can be compensated.
- the actuating device 3 can be easily adapted to the commercially available lids with different thicknesses using the shaped piece 6. With the two struts 4a, 4b arranged in parallel, the respective cover 10 can also be fixed on the different cisterns commercially available.
- a modified housing 30 of the actuating device 3 is shown.
- the housing 30 is formed from a central housing 300 and an annular body 35, the central housing 300 being connected to the annular body 35 by means of two diametrically opposed, approximately S-shaped leaf springs 350.
- From the central housing 300 there is a screw socket 36, onto which the screw sleeve 31 can be screwed as far as it will go on the front side of the central housing 300.
- Two diametrically opposed, radial projections 330 are formed on the ring body 35.
- Each lead is made up of two oppositely strung together U profiles formed, as it is made in particular Fig. 5 can be seen from the drawing.
- a resilient locking tongue 331 is formed in the respective base part of the two U-profiles.
- a strut 4a, 4b with a shaped piece 40b is placed radially on the projections 330, as is particularly the case Fig. 3 can be seen from the drawing.
- recesses 401 are provided in the shaped pieces 40b, in each of which a resilient latching tongue 331 surrounds in the plug-in position and prevents radial pulling out.
- two diametrically opposite, resilient tongues 34 are integrally formed on the end face of the annular body 35 facing the cover 10, as is particularly the case Fig. 4 and Fig. 3 can be seen from the drawing.
- the housing 30, consisting of the central housing 300, the ring body 35, the leaf springs 350 and the spring tongues 34 is made in one piece from plastic by injection molding.
- the struts 4a, 4b each consist of a first part 41a and a second part 41b, as is in particular Fig. 2 can be seen from the drawing.
- the part 41b of the two struts is connected to the drain valve housing of the drain valve 2 and carries a sleeve 42 at its projecting end, each of which has a resilient latching lug 420.
- the associated other part 41a of the two struts has a toothing 43, as is particularly the case Fig. 3 can be seen from the drawing. Since a part 41a is to be inserted into a sleeve 42 at any depth, but not to be pulled out again, the toothing is sawtooth-like, and the detent 420 is also correspondingly sawtooth-like.
- the parts 41a of the two struts 4a, 4b with the shaped piece 40b are first pushed radially onto the projections 330 until they engage.
- the actuating device 3 is connected to the fluid line 5.
- the Actuator 3 with the screw sleeve 31 loosely connected to the cover 10.
- the cover with the parts 41a of the struts 4a, 4b arranged on the actuating device 3 is pushed into the sleeves 42 of the parts 41b of the struts 4a, 4b until the cover lies on the cistern 1 in its covering position.
- the screw sleeve 31 is screwed onto the screw socket 36 of the central housing 300 as far as it will go.
- the two weaker spring tongues 34 cause the two parts 41a of the struts 4a, 4b to be pulled out of the two sleeves 42 until the detents (420) come to rest on one tooth surface of the toothing (43). Then the two more strongly designed S-shaped leaf springs 350 are further deformed until the screw sleeve 31 rests on the end face of the central housing 300.
- the cover 10 of the two struts 4a, 4b can be connected to the housing of the drain valve 2 without play via the two leaf springs 350, the central housing 300 and the screw sleeve 31.
- the lid 10 can only be detached from the cistern 1 if the screw sleeve 31 is first unscrewed from the screw connector 36 of the central housing 300.

Description
Die vorliegende Erfindung betrifft einen Spülkasten mit einem Deckel.The present invention relates to a cistern with a lid.
Bei einer bekannten Ausbildung sind der Deckel und die Betätigungsvorrichtung mittels eines am Ablaufventil angeordneten Gewinderohres gehalten. Hierbei muss jedoch das Gewinderohr jeweils auf die im Handel erhältlichen, verschiedene Abmessungen aufweisenden Spülkästen abgelängt werden, was aufwendig ist. Darüber hinaus müssen auch die in der Schraubhülse angeordneten Betätigungstasten entsprechend angepasst werden.In a known embodiment, the cover and the actuating device are held by means of a threaded tube arranged on the drain valve. Here, however, the threaded pipe must be cut to length on the commercially available cisterns of different dimensions, which is expensive. In addition, the actuation buttons arranged in the screw sleeve must also be adapted accordingly.
Aus der
Auch aus der
Der Erfindung liegt die Aufgabe zugrunde die Betätigungsvorrichtung so auszubilden, dass bei Spülkästen mit unterschiedlichen Abmessungen der Deckel mit relativ einfachen Mitteln sicher in seiner Abdeckposition auf dem Spülkasten gehalten wird. Hierbei gehört es mit zur Aufgabe, Mittel vorzuschlagen, mit denen die Betätigungsvorrichtung an verschiedenen Deckeln mit unterschiedlicher Dicke problemlos befestigt werden kann.The invention is based on the object of designing the actuating device in such a way that, in the case of cisterns with different dimensions, the cover is held securely in its covering position on the cistern with relatively simple means. It is part of the task to propose means with which the actuating device can be easily attached to different lids with different thicknesses.
Diese Aufgabe wird bei einem erfindungsgemäßen Spülkasten gemäß den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved in a cistern according to the invention according to the features of
Dadurch, dass an dem Gehäuse oder dem Gegestück wenigstens eine Halterung für eine Strebe ausgebildet ist, die in der Länge variabel mit dem Ablaufventil verbindbar ist, ist der Deckel in Kombination mit den übrigen Merkmalen sicher und federelastisch auf dem Spülkasten gehalten.Characterized in that at least one bracket for a strut is formed on the housing or the counterpart, the length of which can be variably connected to the drain valve, the cover in combination with the other features is held securely and resiliently on the cistern.
Mit den vorgeschlagenen erfindungsgemäßen Maßnahmen kann die Verbindung des Deckels mit dem am Boden des Spülkastens angeordneten Ablaufventil erheblich vereinfacht werden, da eine individuelle Ablängung eines Gewinderohres entfallen kann.With the proposed measures according to the invention, the connection of the lid to the drain valve arranged at the bottom of the cistern can be considerably simplified, since an individual cut to length of a threaded pipe can be omitted.
Zweckmäßig werden dabei zwei als Zugstangen wirkende diametral gegenüberliegend angeordnete Streben vorgesehen.
Die Streben sind dabei unmittelbar am Gehäuse der Betätigungsvorrichtung an gegenüberliegend angeordneten Aufnahmen mit einem entsprechenden Formstück aufgesteckt werden, wobei die gegenüberliegenden Endbereiche der Streben mit dem Auflegen des Deckels auf den Spülkasten in Rastaufnahmen am Ablaufventil eingesteckt werden können. Dabei sind die Rastaufnahmen so ausgebildet, dass sie ein Einschieben der Streben ermöglichen aber ein Herausziehen verhindern.It is useful to provide two struts arranged diametrically opposite each other as tie rods.
The struts are attached directly to the housing of the actuating device on opposite receptacles with a corresponding shaped piece, the opposite end regions the struts can be plugged into the receptacle on the drain valve by placing the lid on the cistern. The snap-in receptacles are designed so that they allow the struts to be pushed in but prevent them from being pulled out.
Weiterhin wird zur Anpassung an unterschiedlich dicke Deckel des Spülkastens ein federelastisches Ausgleichselement zwischen der Unterseite des Deckels und des Gehäuses bzw. des Gegenstückes angeordnet, der Art, dass die Einschraubtiefe der Schraubhülse in das Gehäuse unabhängig von der Dicke des Deckels gleich bleibt, so dass eine besondere Anpassung von Betätigungstasten der Betätigungseinrichtung nicht mehr erforderlich ist.Furthermore, a spring-elastic compensating element is arranged between the underside of the lid and the housing or the counterpart to adapt to different thickness covers of the cistern, so that the screwing depth of the screw sleeve into the housing remains the same regardless of the thickness of the lid, so that a special adjustment of actuating buttons of the actuating device is no longer required.
Bei der Erfindung weist das Gehäuse ein Zentralgehäuse auf, das ringförmig von einem Ringkörper umgeben ist, wobei der Ringkörper mit zwei diametral gegenüberliegenden Blattfedern axial verschieblich mit dem Zentralgehäuse verbunden ist.In the invention, the housing has a central housing, which is surrounded in a ring shape by an annular body, the annular body being connected to the central housing in an axially displaceable manner by means of two diametrically opposite leaf springs.
Bevorzugt sind dabei diametral gegenüberliegend an dem Ringkörper Vorsprünge angeformt, auf die jeweils eine Strebe mit einem Formkörper radial aufschiebbar ist, wobei an den Vorsprüngen federnde Zungen ausgebildet sind, die in der Stecklage in entsprechende Ausnehmungen im jeweiligen Formstück einfassen und die Strebe in der Stecklage sichern. Hierbei werden zweckmäßig an der dem Deckel zugekehrten Stirnseite des Ringkörpers federnde Zungen ausgebildet, mit denen der Längenunterschied zwischen den einzelnen Raststufen der Streben zum Deckel des Spülkastens ausgeglichen werden kann.Are preferably diametrically opposite projections are formed on the ring body, onto each of which a strut with a molded body can be pushed radially, resilient tongues being formed on the projections, which in the plug-in position surround corresponding recesses in the respective fitting and secure the strut in the plug-in position. In this case, resilient tongues are expediently formed on the end face of the ring body facing the cover, with which the difference in length between the individual latching steps of the struts for the cover of the cistern can be compensated.
Die einzelnen Streben werden dabei vorteilhaft aus zwei Teilen zusammengefügt, wobei ein Teil der Strebe an dem Ablaufventil ausgebildet ist, während der andere Teil mit dem zum Formstück gegenüberliegenden Ende in jeweils eine an der am Ablaufventil befestigten Strebe ausgebildeten Muffe einschiebbar ist. Dabei weist die Muffe eine federnde Zunge auf, die mit einer Verzahnung an dem anderen Teil der Strebe zusammenwirkt, der Art, dass der dem Formstück gegenüberliegende Endbereich jeweils in eine Muffe einschiebbar ist und mit der federnden Zunge gestuft verrastbar ist. Zweckmäßig kann dabei eine sägenzahnartige Verzahnung eingesetzt werden, die ein Einschieben des einen Teils der Strebe in die Muffe des anderen Teils der Strebe ermöglicht aber ein Herausziehen verhindert.The individual struts are advantageously assembled from two parts, one part of the strut being formed on the drain valve, while the other part with the end opposite the shaped piece can be inserted into a sleeve formed on the strut attached to the drain valve. The sleeve has a resilient tongue which interacts with a toothing on the other part of the strut, in such a way that the end region opposite the shaped piece can be inserted into a sleeve and can be locked in steps with the resilient tongue. A sawtooth-like toothing can expediently be used, which allows insertion of one part of the strut into the sleeve of the other part of the strut but prevents it from being pulled out.
Vorteilhaft wird der Ringkörper mit den federnden Zungen, den Blattfedern und dem Zentralgehäuse einstückig aus Kunststoff hergestellt.The ring body with the resilient tongues, the leaf springs and the central housing is advantageously made in one piece from plastic.

Der Spülkasten 1 ist mit einem Deckel 10 verschlossen. An der Außenseite des Deckels 10 ist eine Schraubhülse 31 angeordnet, die mit einem rohrförmigen Zapfen eine Öffnung im Deckel 10 durchdringt und mit einem Schraubstutzen eines Gehäuses 30 einer Betätigungsvorrichtung 3 verschraubt ist. Die Schraubhülse 31 wird dabei bis zum Anschlag am Gehäuse 30 aufgeschraubt, wobei die verschiedenen Wandstärken bei dem im Handel erhältlichen Spülkästen mit einem federelastischen Formkörper 6 aus Moosgummi ausgeglichen wird. In der Schraubhülse 431 ist eine für die Druckbetätigung von außen zugängliche Taste 32 angeordnet. Bei einer Betätigung der Taste 32 wird ein Fluid, z.B. Luft oder Wasser über eine Fluidleitung 5 einem in der Zeichnung nicht dargestellten Ventilheber am Ablaufventil 2 zugeführt, so dass dieses in eine Offenstellung bewegt wird und das im Spülkasten 1 vorhandenes Spülwasser für die WC-Spülung freigegeben wird. Diametral gegenüberliegend sind im Gehäuse 30 zwei Aufnahmen 33 ausgebildet, in die jeweils eines Strebe 4a,4b mit einem Formstück 40a einschiebbar ist. Jede der beiden Streben 4a,4b ist im Anschluss an das Formstück 40a mit blattfederartigen Biegungen 44 versehen, an die sich ein grades Endstück anschließt, das in jeweils eine Rastaufnahme 20 am Ablaufventil 2 einsteckbar und verrastbar ist. Mit Hilfe der blattfederartigen Biegungen 44 kann die z.B. durch eine Verzahnung an den Streben 4a,4b verursachte stufenartige Verrastung kompensiert werden.
Die Betätigungsvorrichtung 3 kann mit Hilfe des Formstückes 6 an die im Handel erhältlichen Deckel mit unterschiedlicher Dicke problemlos angepasst werden. Mit den beiden parallel angeordneten Streben 4a,4b kann außerdem der jeweilige Deckel 10 auf die unterschiedlichen im Handel erhältlichen Spülkästen fixiert werden.In

Bei der Installation des Deckels 10 auf den Spülkasten 1 werden zunächst die Teile 41a der beiden Streben 4a,4b mit dem Formstück 40b auf die Vorsprünge 330 radial bis zur Verrastung aufgeschoben. Außerdem wird die Betätigungsvorrichtung 3 mit der Fluidleitung 5 verbunden. Sodann wird die Betätigungsvorrichtung 3 mit der Schraubhülse 31 lose mit dem Deckel 10 verbunden. Danach wird der Deckel mit den an der Betätigungseinrichtung 3 angeordneten Teilen 41a der Streben 4a,4b in die Muffen 42 der Teile 41b der Streben 4a,4b eingeschoben bis der Deckel in seiner Abdeckposition auf dem Spülkasten 1 liegt. Danach wird die Schraubhülse 31 auf den Schraubstutzen 36 des Zentralgehäuses 300 bis zum Anschlag aufgeschraubt. Hierbei verursachen zunächst die beiden schwächer ausgelegten Federzungen 34, dass die beiden Teile 41a der Streben 4a,4b soweit aus den beiden Muffen 42 herausgezogen werden, bis die Rastnasen (420) an jeweils einer Zahnfläche der Verzahnung (43) zur Anlage gelangen. Danach werden die beiden stärker ausgelegten s-förmigen Blattfedern 350 bis zur Anlage der Schraubhülse 31 an der Stirnseite des Zentralgehäuses 300 weiter verformt. Hierdurch kann von den beiden Streben 4a,4b über die beiden Blattfedern 350, das Zentralgehäuse 300 und die Schraubhülse 31 der Deckel 10 spielfrei mit dem Gehäuse des Ablaufventils 2 verbunden werden. Der Deckel 10 kann nur vom Spülkasten 1 gelöst werden, wenn zunächst die Schraubhülse 31 von dem Schraubstutzen 36 des Zentralgehäuses 300 abgeschraubt wird.When installing the
