Abstract

The actuating device has a tilt button (4) which is mounted on a holder (3) and is connected to the valve body (8) of a discharge valve, via a two-armed lever (6), such that, when the tilt button (4) is pivoted, the valve body (8) can be lifted in order to open the discharge valve. The lever (6) is mounted in a frame (7), an engagement part of the lever (6) rolling, without sliding, on a rolling-contact curve (7b) of the frame (7) when the tilt button (4) is actuated. In this arrangement, the turning point of the lever (6) is displaced such that the comparatively large initial force reduction decreases continuously and the path reduction increases. As a result, the discharge valve can be opened by a small amount of force, with a relatively small button displacement. <IMAGE>

Description

Die Erfindung betrifft eine Betätigungsvorrichtung für das Ablaufventil eines Spülkastens gemäss Oberbegriff des Anspruchs 1.The invention relates to an actuating device for the drain valve of a cistern according to the preamble of claim 1.

Eine Betätigungsvorrichtung der genannten Art ist durch die CH-A-665 865 des Anmelders bekannt geworden. Diese weist eine im Spülkasten gelagerte Wipptaste auf, die von Hand zur Auslösung des Spülvorganges verschwenkt werden kann. Durch Zurückschwenken der Wipptaste kann bei Bedarf die Spülung vor der vollständigen Entleerung des Spülkastens unterbrochen werden. Die Bedienung der Betätigungsvorrichtung ist damit sehr einfach und gleichzeitig kann der Spülwasserverbrauch drastisch vermindert werden. Zudem lässt sich eine solche Betätigungsvorrichtung mit vergleichsweise wenigen und robusten Bauteilen kostengünstig realisieren. Die Betätigungsvorrichtung eignet sich auch für das Ablaufventil von Unterputz-Spülkästen, wie die CH-A-651 341 zeigt.An actuator of the type mentioned is known from the applicant's CH-A-665 865. This has a rocker button mounted in the cistern, which can be swiveled by hand to trigger the flushing process. If necessary, the flushing can be interrupted before the cistern is completely emptied by swiveling the rocker button back. The operation of the actuating device is therefore very simple and at the same time the consumption of flushing water can be drastically reduced. In addition, such an actuating device can be implemented inexpensively with comparatively few and robust components. The actuator is also suitable for the drain valve of concealed cisterns, as shown in CH-A-651 341.

Die Erfinder haben sich nun die Aufgabe gestellt, eine Betätigungsvorrichtung der genannten Art zu schaffen, die bei geringerer Raumbeanspruchung zugleich bedienungsfreundlicher ist. Die oben genannten Vorteile sollen hierbei erhalten bleiben. Die Aufgabe ist durch die Erfindung gemäss Anspruch 1 gelöst.The inventors have now set themselves the task of creating an actuating device of the type mentioned, which is also easier to use with less space. The advantages mentioned above should be retained. The object is achieved by the invention according to claim 1.

Durch die Verschiebung des Drehpunktes während der Betätigung nimmt die Kraftuntersetzung ab und die Weguntersetzung zu. Die Zunahme der Weguntersetzung hat zur Folge, dass der Tastenhub kleiner wird, ohne dass eine Veränderung am Ablaufventil notwendig ist. Die Kraftuntersetzung hat zur Folge, dass die Spülung mit geringerem Druck auf die Taste ausgelöst werden kann. Die zu Anfang einer Spülung vergleichsweise hohe Last des Ventilkörpers am zweiarmigen Hebel, verursacht durch den Druck des Spülwassers auf dem Ventilteller, kann somit mit geringerem Kraftaufwand überwunden werden. Bei einer Spülunterbrechung ist es dann auch bei kleinem Kraftaufwand möglich, den Ventilkörper in die Schliessstellung zu bringen. Die Betätigung ist somit auch bei einer Unterbrechung bedienungsfreundlicher.By shifting the fulcrum during actuation, the force reduction and the path reduction increase. The increase in the step-down ratio means that the key travel becomes smaller without the need to change the drain valve. The force reduction means that the flushing can be triggered with less pressure on the button. The comparatively high load of the valve body on the two-armed lever at the beginning of a flushing, caused by the pressure of the flushing water on the valve plate, can thus be overcome with less effort. If the flushing is interrupted, it is then possible to bring the valve body into the closed position even with little effort. The operation is therefore more user-friendly even when there is an interruption.

Der kleinere Hub hat einen wesentlicheren Vorteil, dass die Taste in den beiden Endstellungen auf der Oberseite des Spülkastendeckels weniger vorsteht bzw. weniger in diesem versenkt wird.The smaller stroke has a more important advantage that the button protrudes less on the top of the cistern lid in the two end positions or is sunk less.

Die erfindungsgemässe Betätigungsvorrichtung ist somit trotz kompakterer Bauweise bei gleicher Anzahl Einzelteile bedienungsfreundlicher als die bekannten Vorrichtungen dieser Art. Durch die kompaktere Bauweise der Betätigungsvorrichtung sind das Einlauf- und das Ablaufventil für Einstell- und Revisionsarbeiten besser zugänglich.The actuating device according to the invention is therefore more user-friendly than the known devices of this type, despite the more compact design with the same number of individual parts. The more compact design of the actuating device makes the inlet and the outlet valve more accessible for adjustment and revision work.

Nach einer Weiterbildung der Erfindung ist der Hebel ohne gleiten auf einer Wälzkurve des Gestells abrollbar gelagert. Ein solches Lager kann kostengünstig mit Kunststoffteilen hergestellt werden und ist sehr robust sowie wartungsfrei.According to a development of the invention, the lever is mounted such that it can be rolled on a rolling curve of the frame without sliding. Such a bearing can be manufactured inexpensively with plastic parts and is very robust and maintenance-free.

Eine in konstruktiver Hinsicht besonders vorteilhafte Führung des Hebels wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass vor und nach der Wälzkurve des Gestells nach oben verlaufende Gleitflächen anschliessen, an denen der Hebel formschlüssig geführt ist. Das Lager und die Führung des Hebels kann dann durch einen herzförmigen Ausschnitt des Gestells realisiert werden. Ist der herzförmige Ausschnitt oben offen, so kann der Hebel bei der Montage von oben in den Ausschnitt eingesetzt werden, was eine besonders einfache und funktionssichere Verbindung ergibt. Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen und der nachfolgenden Beschreibung sowie der Zeichnung.A particularly advantageous design of the lever is achieved according to a further development of the invention in that before and after the rolling curve of the frame, upward sliding surfaces are connected, to which the lever is guided in a form-fitting manner. The bearing and the guidance of the lever can then be realized by a heart-shaped cutout of the frame. If the heart-shaped cutout is open at the top, the lever can be inserted into the cutout from above, which results in a particularly simple and functionally reliable connection. Further advantageous features result from the dependent claims and the following description and the drawing.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine Teilansicht eines Spülkastens mit einer montierten erfindungsgemässen Betätigungsvorrichtung,
  • Fig. 2 eine weitere Ansicht der Betätigungsvorrichtung nach Fig. 1, und
  • Fig. 3a bis 3d schematische Teilansichten der erfindungsgemässen Betätigungsvorrichtung.
An embodiment of the invention is explained below with reference to the drawing. Show it:
  • 1 is a partial view of a cistern with a mounted actuating device according to the invention,
  • Fig. 2 shows a further view of the actuating device according to Fig. 1, and
  • 3a to 3d are schematic partial views of the actuating device according to the invention.

Die Betätigungsvorrichtung weist einen Halter 3 auf, der vorzugsweise lösbar mit einer Vorderwand 1a und einer Rückwand 1b eines Spülkastenkörpers 1 verbunden ist. Am Halter 3 ist ein nach oben ragender Lagerteil 3a für eine Wipptaste 4 angeformt. Zwei am Lagerteil 3a angeformte Lagerzapfen 3b greifen in Lagerschlitze 4b der Wipptaste 4 ein. Die Oberseite 4a der Wipptaste 4 ist gemäss Fig. 2 geneigt und bündig zur Oberseite 2a eines Spülkastendeckels 2, der eine Oeffnung 2b für die Taste 4 aufweist.The actuating device has a holder 3, which is preferably detachably connected to a front wall 1a and a rear wall 1b of a cistern body 1. An upwardly projecting bearing part 3a for a rocker button 4 is formed on the holder 3. Two bearing pins 3b formed on the bearing part 3a engage in bearing slots 4b of the rocker button 4. The top 4a of the rocker button 4 is inclined according to FIG. 2 and is flush with the top 2a of a cistern lid 2, which has an opening 2b for the button 4.

Im Spülkasten ist ein Schwimmerventil angeordnet, von dem hier lediglich der obere Teil des Ventilkörpers 8 gezeigt ist. Das Schwimmerventil ist ein an sich bekanntes Ablaufventil und der Ventilkörper 8 ist in der Regel gleichzeitig ein Ueberlaufrohr. Zur Auslösung des Spülvorganges wird der Ventilkörper 8 durch ein Verschwenken der Wipptaste 4 angehoben. Die hierzu nötige Anfangskraft ist vergleichsweise hoch, da der Ventilkörper 8 durch den Druck des Spülwassers auf den Ventilsitz gedrückt wird. Am oberen Ende des Ventilkörpers 8 ist eine Oese 8a angeformt, in die ein zapfenförmiger Mitnehmer 6b eines Hebels 6 eingreift. Ein weiterer zapfenförmiger Mitnehmer 6a des Hebels 6 ist in einen vorne offenen Führungsschlitz 4d der Taste 4 eingesetzt. Der Hebel 6 ist in einem Gestell 7 gelagert, das am Halter 3 abgestützt ist. Der Hebel 6 und das Gestell 7 bilden ein Getriebe, das Schwenkbewegungen der Taste 4 in vertikale Bewegungen des Ventilkörpers 8 umwandelt. Wird die Taste 4 an der Stelle und in Richtung des Pfeiles 5 verschwenkt, so wird der Ventilkörper 8 angehoben und somit das Ablaufventil geöffnet. Wird die Taste 4 losgelassen, so fällt der Ventilkörper 8 nach der vollständigen Entleerung des Spülkastens zurück auf den Ventilsitz und lässt über den Hebel 6 die Taste 4 zurück in die in Fig. 1 und 2 gezeigte Ruhelage fallen. Wird vor der vollständigen Entleerung des Spülkastens die Wipptaste 4 am oberen Ende in Richtung des Pfeiles 9 in die genannte Ruhelage gedrückt, so wird wieder über den Hebel 6 der Ventilkörper nach unten bewegt und das Ablaufventil geschlossen. Auf diese Weise kann der Spülvorgang vorzeitig unterbrochen werden, wenn nicht die gesamte Spülwassermenge benötigt wird.A float valve is arranged in the cistern, of which only the upper part of the valve body 8 is shown here. The float valve is a drain valve known per se and the valve body 8 is usually an overflow pipe at the same time. To trigger the flushing process, the valve body 8 is raised by pivoting the rocker button 4. The initial force required for this is comparatively high since the valve body 8 is pressed onto the valve seat by the pressure of the flushing water. At the An eyelet 8a is integrally formed in the upper end of the valve body 8, into which a peg-shaped driver 6b of a lever 6 engages. Another peg-shaped driver 6a of the lever 6 is inserted into a guide slot 4d of the button 4 which is open at the front. The lever 6 is mounted in a frame 7 which is supported on the holder 3. The lever 6 and the frame 7 form a gear that converts the pivoting movements of the button 4 into vertical movements of the valve body 8. If the button 4 is pivoted at the point and in the direction of the arrow 5, the valve body 8 is raised and the drain valve is thus opened. If the button 4 is released, the valve body 8 falls back onto the valve seat after the cistern has been completely emptied and, via the lever 6, the button 4 falls back into the rest position shown in FIGS. 1 and 2. If the rocker switch 4 at the upper end in the direction of arrow 9 is pressed into said rest position before the cistern is completely emptied, the valve body is moved down again via the lever 6 and the drain valve is closed. In this way, the flushing process can be interrupted prematurely if the entire amount of flushing water is not required.

Der Hebel 6 ist vorzugsweise aus einem Stück aus geeignetem Kunststoff hergestellt und weist zwischen den Mitnehmern 6a und 6b zwei parallele und quer zur Drehachse verlaufende Führungsteile 6c und zwischen diesen einen Eingriffsteil 6d auf. Der Hebel 6 ist in einem oben offenen Ausschnitt 7c des Gestells 7 gelagert. Das Lager ist ein Wälzlager bei welcher der Eingriffsteil 6d ohne zu gleiten auf einer nach oben gebogenen Wälzkurve 7b des Gestells 7 abrollt. Die Wälzkurve 7c des Mitnehmerteils 6d ist vorzugsweise gerade. Vor und nach der Wälzkurve 7b weist das Gestell 7 nach oben verlaufende Führungsrechen 7a auf, an denen der Eingriffsteil 6d gleitend geführt ist. Wesentlich ist nun, dass der Drehpunkt des Hebels 6 sich während einer Betätigung derart verschiebt, dass der Kraftarm beim Anheben des Ventilkörpers laufend kürzer und der Lastarm entsprechend laufend grösser wird. Zum Oeffnen des Ablaufventils wird dadurch eine grosse Kraftuntersetzung und anschliessend zunehmende Weguntersetzung erreicht. Der anfängliche grosse Kraftaufwand zum Anheben des Ventilkörpers 8 ist somit an der Taste 4 stark untersetzt, während nach dem Oeffnen des Ablaufventils der Ventilkörper 8 dennoch mit vergleichsweise geringer Hub der Taste 4 vollständig angehoben werden kann. Dies soll anhand der Fig. 3a bis 3d näher erläutert werden.The lever 6 is preferably made from a single piece of suitable plastic and has between the drivers 6a and 6b two parallel and transverse to the axis of rotation guide parts 6c and between them an engagement part 6d. The lever 6 is mounted in a cutout 7c of the frame 7 which is open at the top. The bearing is a roller bearing in which the engagement part 6d without slide on an upwardly curved rolling curve 7b of the frame 7 rolls. The pitch curve 7c of the driver part 6d is preferably straight. Before and after the rolling curve 7b, the frame 7 has upwardly extending guide rakes 7a, on which the engaging part 6d is slidably guided. It is now essential that the fulcrum of the lever 6 shifts during actuation in such a way that the power arm is continuously shorter and the load arm is correspondingly continuously larger when the valve body is raised. In order to open the drain valve, a large reduction in force and subsequently increasing displacement are achieved. The initial great effort to lift the valve body 8 is thus greatly reduced at the button 4, while after opening the drain valve the valve body 8 can still be raised completely with a comparatively small stroke of the button 4. This will be explained in more detail with reference to FIGS. 3a to 3d.

Die Fig. 3a zeigt den Hebel 6 bei geschlossenem Ablaufventil. Der ungefähre Angriffspunkt des Mitnehmers 6a ist mit C, derjenige des Mitnehmers 6b mit A und der Auflagepunkt des Hebels 6 mit B bezeichnet. Wie ersichtlich, ist der Abstand der Punkte B und C wesentlich grösser als der Abstand der Punkte A und B. Wird nun die Wipptaste 4 in Richtung des Pfeils 5 verschwenkt, so wird der Hebel 6 um den Punkt B verschwenkt, wobei der Angriffspunkt A angehoben und somit das Ablaufventil geöffnet wird. Die hierbei wirksame Kraftuntersetzung entspricht dem Verhältnis der genannten Abstände. Die Lage des Hebels 6 kurz nach dem Oeffnen des Ablaufventils ist in Fig. 3b gezeigt. Wird nun die Taste 4 weiter in gleicher Richtung verschwenkt, so wandert der Punkt B auf der Wälzkurve 7b nach rechts und entsprechend nimmt die Länge des Kraftarmes ab, während diejenige des Lastarmes zunimmt. In Fig. 3c ist der Hebel 6 in einer Position gezeigt, in welcher der Ventilkörper 8 etwa zur Hälfte angehoben ist. Der Auflagepunkt B′ befindet sich etwa in der Mitte der Wälzkurve 7b. Schliesslich zeigt die Fig. 3 die Lage des Hebels 6 bei vollständig angehobenem Ventilkörper 8. Der Drehpunkt B˝ befindet sich nun am rechten Ende der Wälzkurve 7b. Beim Uebergang von der Position nach Fig. 3c in die Position nach Fig. 3d wird die Weguntersetzung ständig grösser. Beim Schliessen des Ablaufventils gilt dann das umgekehrte. Die Kraftuntersetzung nimmt dann zu und die Weguntersetzung ab. Bei einer Spülunterbrechung sind die Hebelverhältnisse ebenfalls vorteilhaft, da der Ventilkörper 8 anfänglich sehr schnell nach unten bewegt wird und die Kraftuntersetzung dann am grössten ist, wenn der Ventilkörper gegen die nach oben wirkende Kraft des ausströmenden Spülwassers auf den Ventilsitz gedrückt werden muss.3a shows the lever 6 with the drain valve closed. The approximate point of engagement of the driver 6a is designated by C, that of the driver 6b by A and the contact point of the lever 6 by B. As can be seen, the distance between points B and C is considerably greater than the distance between points A and B. If the rocker switch 4 is now pivoted in the direction of arrow 5, the lever 6 is pivoted about point B, the point of attack A being raised and thus the drain valve is opened. The effective reduction in force corresponds to the ratio of the distances mentioned. The position of lever 6 shortly after opening the drain valve is shown in Fig. 3b. If the button 4 is now pivoted further in the same direction, point B on the pitch curve 7b moves to the right and the length of the power arm decreases accordingly, while that of the load arm increases. In Fig. 3c, the lever 6 is shown in a position in which the valve body 8 is raised about half. The bearing point B 'is located approximately in the middle of the pitch curve 7b. Finally, FIG. 3 shows the position of the lever 6 with the valve body 8 fully raised. The pivot point B˝ is now at the right end of the rolling curve 7b. When moving from the position according to FIG. 3c to the position according to FIG. 3d, the step-down ratio is constantly increasing. The reverse applies when the drain valve is closed. The force reduction then increases and the path reduction decreases. In the event of an interruption in flushing, the lever ratios are also advantageous since the valve body 8 is initially moved very quickly downward and the force reduction is greatest when the valve body has to be pressed onto the valve seat against the upward force of the outflowing flushing water.

Damit die Taste 4 immer in eine genau definierte Ruhelage zurückgeht, ist die Gewichtsverteilung so gewählt, dass sich in der Ansicht nach Fig. 2 bezüglich der Achse 3b ein Drehmoment im Gegenuhrzeigersinn ergibt. Dies kann beispielsweise durch eine entsprechend grosse oder massive Ausbildung eines hinteren Bereichs 3e erreicht werden. Ein Spiel des Mitnehmers 6b in der Oese 8a hat damit keinen Einfluss auf die Ruhelage der Taste 4.So that the button 4 always returns to a precisely defined rest position, the weight distribution is selected so that in the view according to FIG. 2 there is a torque in the counterclockwise direction with respect to the axis 3b. This can be achieved, for example, by a correspondingly large or massive design of a rear region 3e. A play of the driver 6b in the eyelet 8a thus has no influence on the rest position of the button 4.
