Description

Die Erfindung betrifft einen Spülkasten mit einem Deckel für ein WC oder dergleichen, wobei eine Betätigungsvorrichtung für ein am Boden des Spülkastens angeordnetes Ablaufventil vorgesehen ist, die mit einer von außen einsetzbaren, den Deckel in einer Öffnung wenigstens zum Teil durchgreifenden Schraubhülse und einem an der Innenseite des Deckels angeordneten Gegenstück oder Gehäuse befestigt ist.The invention relates to a cistern with a lid for a toilet or the like, wherein an actuating device for a arranged at the bottom of the cistern discharge valve is provided with an externally applicable, the lid in an opening at least partially cross-threaded and a sleeve on the inside the cover arranged counterpart or housing is attached.

Bei einer bekannten Ausbildung ist 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 of the lid and the actuator is held by means of a drain valve arranged on the threaded tube. In this case, however, the threaded pipe must be cut to the commercially available, various dimensions having cisterns each, which is expensive. In addition, also arranged in the screw actuator buttons must be adjusted accordingly.

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 has the object of providing the actuator so that in cisterns with different dimensions of the lid with relatively simple means is securely held in its covering position on the cistern. Here it is part of the task to propose means by which the actuator can be easily attached to different lids with different thickness.

Diese Aufgabe wird bei einem gattungsgemäßen Spülkasten dadurch gelöst, dass an dem Gehäuse oder dem Gegenstück wenigstens eine Halterung für eine Strebe ausgebildet ist, die in der Länge variabel mit dem Ablaufventil verbindbar ist, so dass der Deckel sicher auf dem Spülkasten gehalten ist.This object is achieved in a generic cistern in that at least one holder for a strut is formed on the housing or the counterpart, which is variable in length connected to the drain valve, so that the lid is securely held on the cistern.

Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 13 angegeben.Further embodiments of the invention are specified in claims 2 to 13.

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. Zweckmäßig werden dabei zwei als Zugstangen wirkende diametral gegenüberliegend angeordnete Streben vorgesehen.With the proposed measures according to the invention, the connection of the lid with the arranged at the bottom of the cistern discharge valve can be considerably simplified, since an individual lengthening of a threaded tube can be omitted. Suitably, two diametrically opposed struts acting as tie rods are provided.

Die Streben können 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 ermögfichen aber ein Herausziehen verhindern.The struts can be attached directly to the housing of the actuator on opposing receptacles arranged with a corresponding fitting, the opposite end portions of the struts can be inserted with the laying of the lid on the cistern in locking receptacles on the drain valve. The locking receptacles are designed so that they allow insertion of the struts but prevent withdrawal.

In weiterer Ausgestaltung der Erfindung kann zur Anpassung an unterschiedlich dicke Deckel des Spülkastens zweckmäßig ein federelastisches Ausgleichselement zwischen der Unterseite des Deckels und des Gehäuses bzw. des Gegenstückes angeordnet werden, 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. Als federelastisches Ausgleichselement kann beispielsweise eine Schraubenfeder, Blattfedern oder ein Moosgummiformkörper eingesetzt werden.In a further embodiment of the invention, a resilient compensation element between the underside of the lid and the housing or the counterpart can be arranged to adapt to different thickness lid of the cistern suitably, the way that the depth of insertion of the screw into the housing regardless of the thickness of the lid remains the same, so that a special adjustment of operation buttons of the actuator is no longer required. As a resilient compensation element, for example, a coil spring, leaf springs or a foam rubber body can be used.

Zum Längenausgleich bei der Verwendung von gestuften Rastpositionen der Streben können die Streben blattfederartige Biegungen aufweisen.For length compensation in the use of stepped detent positions of the struts, the struts may have leaf spring-like bends.

In einer anderen Ausgestaltung 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. Diametral gegenüberliegend sind dabei 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. 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.In another embodiment of the invention, the housing has a central housing which is annularly surrounded by an annular body, wherein the annular body with two diametrically opposed leaf springs is axially displaceably connected to the central housing. Diametrically opposite are projections formed on the annular body, on each of which a strut with a shaped body is radially slidable, wherein on the projections resilient tongues are formed, which engage in the insertion position into corresponding recesses in the respective fitting and secure the strut in the inserted position. In this case, resilient tongues are expediently formed on the end face of the annular body facing the cover, with which the difference in length between the individual latching stages of the struts can be compensated for the lid of the cistern. The individual struts are advantageously joined together from two parts, wherein a part of the strut is formed on the drain valve, while the other part with the opposite end to the fitting in each case one formed on the attached to the drain valve strut sleeve is inserted. In this case, the sleeve has a resilient tongue which cooperates with a toothing on the other part of the strut, the way that the end portion opposite the fitting is in each case inserted into a sleeve and can be latched stepped with the resilient tongue. Appropriately, a sawtooth-like toothing can be used, which allows insertion of one part of the strut in the sleeve of the other part of the strut but prevents withdrawal.

Vorteilhaft wird der Ringkörper mit den federnden Zungen, den Blattfedern und dem Zentralgehäuse einstückig aus Kunststoff hergestellt.Advantageously, the annular body with the resilient tongues, the leaf springs and the central housing is made in one piece from plastic.

Der Einfachheit halber sind bei den Ausführungsbeispielen in der Zeichnung gleiche oder entsprechende Elemente mit jeweils gleichen Bezugszeichen versehen.For the sake of simplicity, the same or corresponding elements are provided with the same reference numerals in the embodiments in the drawing.

In Fig. 1 der Zeichnung ist ein Spülkasten 1 gezeigt, in dessen Boden 11 ein Ablaufventil 2 in einer Öffnung befestigt ist. An einem Anschlussstutzen 21 des Ablaufventils 2 kann eine in der Zeichnung nicht dargestellte Spulleitung für ein WC angeschlossen werden. Der Spülkasten 1 wird von einem in der Zeichnung nicht dargestellten schwimmergesteuerten Zulaufventil bis zu einem bestimmten Niveau mit Spülwasser gefullt.In Fig. 1 of the drawing, a cistern 1 is shown, in the bottom 11, a drain valve 2 is fixed in an opening. At a connecting piece 21 of the drain valve 2, a Spulleitung not shown in the drawing for a toilet can be connected. The cistern 1 is filled by a float-controlled inlet valve, not shown in the drawing up to a certain level with rinse water.

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 41 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 zugeführe, so dass dieses in eine Offenstellung bewegt wird und das im Spülkasten 1 vorhandenes Spülwasser für die WC-Spülung freigegeben wird.The cistern 1 is closed with a lid 10. On the outside of the lid 10, a screw sleeve 31 is arranged, which penetrates with a tubular pin an opening in the lid 10 and is screwed to a screw socket of a housing 30 of an actuating device 3. The screw sleeve 31 is thereby screwed to the stop on the housing 30, wherein the different wall thicknesses is compensated in the cisterns available in the trade with a resilient molding 6 made of sponge rubber. In the threaded sleeve 41 for the printing operation externally accessible button 32 is arranged. Upon actuation of the key 32, a fluid, eg air or water, is supplied via a fluid line 5 to a valve lifter (not shown in the drawing) on the drain valve 2, so that it is moved into an open position and in the Cistern 1 existing rinse water for toilet flushing is released.

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 Formstuck 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.Diametrically opposite two receptacles 33 are formed in the housing 30, in each of which a strut 4a, 4b with a molding 40a is inserted. Each of the two struts 4a, 4b is provided subsequent to the molded piece 40a with leaf spring-like bends 44, which is followed by a straight end piece, which can be inserted and latched into a respective latching receptacle 20 on the drain valve 2. By means of the leaf spring-like bends 44, the e.g. by a toothing on the struts 4a, 4b caused step-like locking can be compensated.

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.The actuator 3 can be easily adapted by means of the fitting 6 to the commercially available cover with different thickness. In addition, with the two parallel struts 4a, 4b, the respective cover 10 can be fixed to the different commercially available cisterns.

Bei dem in Fign. 2 bis 5 der Zeichnung dargestellten Ausführungsbeispiel ist ein abgewandeltes Gehäuse 30 der Betätigungsvorrichtung 3 dargestellt. Das Gehäuse 30 wird dabei aus einem Zentralgehäuse 300 und einem Ringkörper 35 gebildet, wobei das Zentralgehäuse 300 mit dem Ringkörper 35 über zwei diametral gegenüberliegend angeordneten, etwa s-förmigen Blattfedern 350 verbunden ist. Aus dem Zentralgehäuse 300 steht ein Schraubstutzen 36 vor, auf den die Schraubhülse 31 bis zum Anschlag an der Stirnseite des Zentralgehäuses 300 aufschraubbar ist.In the case of FIG. 2 to 5 of the drawing illustrated embodiment, a modified housing 30 of the actuator 3 is shown. The housing 30 is formed from a central housing 300 and an annular body 35, wherein the central housing 300 is connected to the annular body 35 via two diametrically opposed, approximately s-shaped leaf springs 350 is connected. From the central housing 300 is a screw socket 36, to which the screw sleeve 31 can be screwed to the stop on the end face of the central housing 300.

Am Ringkörper 35 sind zwei diametral gegenüberliegende, radiale Vorsprünge 330 angeformt. Jeder Vorsprung ist aus zwei gegenläufig aneinandergereihten U-Profilen gebildet, wie es insbesondere aus Fig. 5 der Zeichnung zu entnehmen ist. Im jeweiligen Basisteil der beiden U-Profile ist jeweils eine federnde Rastzunge 331 ausgebildet. Auf die Vorsprünge 330 wird jeweils eine Strebe 4a,4b mit einem Formstück 40b radial aufgesteckt, wie es insbesondere aus Fig. 3 der Zeichnung zu entnehmen ist. Zur Sicherung in der Stecklage sind in den Formstücken 40b Ausnehmungen 401 vorgesehen, in die in der Stecklage jeweils eine federnde Rastzunge 331 einfasst und ein radiales Herausziehen verhindert.On the annular body 35, two diametrically opposed, radial projections 330 are formed. Each projection is formed from two oppositely juxtaposed U-profiles, as can be seen in particular from Fig. 5 of the drawing. In the respective base part of the two U-profiles is respectively a resilient latching tongue 331 is formed. A strut 4a, 4b with a shaped piece 40b is radially attached to the projections 330, as can be seen in particular from FIG. 3 of the drawing. For securing in the inserted position 40b recesses 401 are provided in the fittings, in each of which a resilient latching tongue 331 engages in the inserted position and prevents radial withdrawal.

Außerdem sind an der dem Deckel 10 zugekehrten Stirnseite des Ringkörpers 35 zwei diametral gegenüberliegende, federnde Zungen 34 angeformt, wie es insbesondere aus Fig. 4 und Fig. 3 der Zeichnung zu entnehmen ist.In addition, two diametrically opposite, resilient tongues 34 are integrally formed on the lid 10 facing the end face of the annular body 34, as can be seen in particular from Fig. 4 and Fig. 3 of the drawing.

Das Gehäuse 30, bestehend aus dem Zentralgehäuse 300, dem Ringkörper 35, den Blattfedern 350 und den Federzungen 34 ist einstückig aus Kunststoff im Spritzgießverfahren hergestellt.The housing 30, consisting of the central housing 300, the annular body 35, the leaf springs 350 and the spring tongues 34 is manufactured in one piece from plastic by injection molding.

Die Streben 4a,4b bestehen jeweils aus einem ersten Teil 41a und einem zweiten Teil 41b, wie es insbesondere aus Fig. 2 der Zeichnung zu entnehmen ist. Der Teil 41b der beiden Streben ist mit dem Ablaufventilgehäuse des Ablaufventils 2 verbunden und trägt an seinem vorstehenden Ende eine Muffe 42, die jeweils eine federnde Rastnase 420 aufweist. Der zugehörige andere Teil 41a der beiden Streben trägt eine Verzahnung 43, wie es insbesondere aus Fig. 3 der Zeichnung zu entnehmen ist. Da jeweils ein Teil 41a in jeweils eine Muffe 42 beliebig tief einschiebbar aber nicht wieder herausziehbar sein soll, ist die Verzahnung sägezahnartig ausgebildet, wobei auch die Rastnase 420 entsprechend sägezahnartig ausgebildet ist.The struts 4a, 4b each consist of a first part 41a and a second part 41b, as can be seen in particular from FIG. 2 of the drawing. The part 41b of the two struts is connected to the drain valve housing of the drain valve 2 and carries at its projecting end a sleeve 42, each having a resilient latch 420. The associated other part 41a of the two struts carries a toothing 43, as can be seen in particular from Fig. 3 of the drawing. Since in each case a part 41a in each case a sleeve 42 can be pushed in any depth but not pulled out again, the toothing is formed like a sawtooth, wherein the locking lug 420 is formed according to a sawtooth.

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 Zentratgehäuse 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 lid 10 on the cistern 1, the parts 41a of the two struts 4a, 4b are first pushed with the fitting 40b on the projections 330 radially to the catch. In addition, the actuator 3 is connected to the fluid line 5. Then, the actuator 3 with the screw 31 is loosely connected to the lid 10. Thereafter, the lid with the on the actuator 3 arranged parts 41 a of the struts 4 a, 4 b inserted into the sleeves 42 of the parts 41 b of the struts 4 a, 4 b until the lid is in its covering position on the cistern 1. Thereafter, the screw sleeve 31 is screwed onto the screw socket 36 of the central housing 300 to the stop. Initially cause the two weaker designed spring tongues 34 that the two parts 41 a of the struts 4 a, 4 b are pulled out of the two sleeves 42 until the locking lugs (420) on each tooth surface of the toothing (43) come to rest. Thereafter, the two stronger s-shaped leaf springs 350 are further deformed until the installation of the screw sleeve 31 on the front side of the central housing 300 .. This can be from the two struts 4a, 4b on the two leaf springs 350, the centrate housing 300 and the screw sleeve 31 of Cover 10 are connected without play with the housing of the drain valve 2. The lid 10 can only be solved by the cistern 1, when first the screw sleeve 31 is unscrewed from the screw socket 36 of the central housing 300.
