Die Vorrichtung 1 ist ein Handdrücker, auch Taster genannt, der im wesentlichen aus einem Gehäuse 2, einem Deckel 3, zwei Tasten 4 und 5, zwei Bälgen 6 und einem im unteren Teil des Gehäuses gelagerten Halte- und Führungsteil 8 besteht. Diese Teile sind lösbar durch Rastmittel und Zusammenstecken miteinander verbunden. Die einzelnen Teile sind somit ohne Verwendung von Werkzeugen und zerstörungsfrei auswechselbar. Auch die Montage erfolgt ohne Verwendung von Werkzeugen durch Rastmittel, die weiter unten noch näher erläutert werden.The device 1 is a hand lever, also called a button essentially from a housing 2, a cover 3, two buttons 4 and 5, two bellows 6 and one in the lower part of the housing stored holding and guiding part 8. These parts are releasable by locking means and plugging together connected. The individual parts are therefore without the use of Exchangeable tools and non-destructive. Even the assembly takes place without the use of tools by locking means are explained in more detail below.

Das Gehäuse 2 ist dosenförmig ausgebildet und weist in seinem Boden vier Befestigungsstellen 26 auf, mit denen das Gehäuse mit hier nicht gezeigten Schrauben in einer Nische einer Gebäudewand befestigbar ist. Ebenfalls im-Boden sind zwei Öffnungen 24 eingearbeitet, durch die jeweils eine flexible Druckleitung 27 (Figur- 2) hindurchgezogen werden. Im Innern des Gehäuses 2 sind diese Druckleitungen 27 jeweils an einem Nippel 9 angeschlossen.The housing 2 is can-shaped and has in its Bottom four attachment points 26 with which the housing with Screws not shown here in a niche of a building wall is attachable. Two openings 24 are also incorporated in the base, through the respective flexible pressure line 27 (Figure 2) are pulled through. Inside the housing 2 are these pressure lines 27 are each connected to a nipple 9.

In das Gehäuse 2 ist ein Halte- und Führungsteil 8 eingesetzt, an dem die beiden Nippel 9, die beiden Bälge 6, die beiden Tasten 4 und 5 sowie die Rahmenabdeckung 3 lösbar befestigt sind. Die beiden Nippel 9 sind von der Unterseite des Teils 8 jeweils luftdicht in einen rohrförmigen, gummielastischen Ansatz 28 eines Balges 6 eingesetzt. Wie die Figur 2 zeigt, überragt das obere Ende des Nippels 9 die Öffnung 28 und greift in eine korrespondierende, hier nicht näher bezeichnete Öffnung des Ansatzes 28 ein. Die Nippel 9 verbinden jeweils eine pneumatische Leitung 27 mit einem Balg 6.A holding and guiding part 8 is inserted into the housing 2, on which the two nipples 9, the two bellows 6, the two buttons 4 and 5 and the frame cover 3 are releasably attached. The two nipples 9 are from the bottom of part 8, respectively airtight in a tubular, rubber-elastic approach 28 one Bellows 6 used. As Figure 2 shows, this towers over upper end of the nipple 9, the opening 28 and engages in a corresponding, opening of the approach not specified here 28 a. The nipples 9 each connect a pneumatic one Line 27 with a bellows 6.

Zur Befestigung der beiden Bälge 6 weist das Halte- und Führungsteil 8 gemäss Figur 6 einen Schlitz 14 auf, der eine grosse kreisförmige Öffnung 14d sowie drei kleinere Erweiterungen 14a, 14b und 14c besitzt. Die Bälge 6 weisen zu ihrer Befestigung in diesem Schlitz 14 jeweils auf der Unterseite einen tellerförmigen Ansatz 12 auf, wie die Figur 4 deutlich zeigt. Um einen ersten Balg am Teil 8 zu befestigen, wird der Teller 12 durch die grosse Öffnung 14d eingesetzt und der Balg 6 im Schlitz 14 in Figur 6 nach links verschoben, bis der Teller 12 den Schlitz 14 in die Erweiterung 14a einrastet. Ein zweiter Balg 6 wird ebenfalls mit seinem Teller 12 durch die Öffnung 14d eingesetzt und in Figur 6 nach rechts verschoben bis zur Erweiterung 14c. Ist lediglich ein Balg 6 vorgesehen, so wird dieser in Figur 6 bis zur Erweiterung 14b verschoben. Die Erweiterung 14b erlaubt somit die lösbare Befestigung eines einzigen Balges 6 etwa in der Mitte des Gehäuses 2.To hold the two bellows 6, the holding and guiding part 8 according to FIG. 6 has a slot 14 which has a large one circular opening 14d and three smaller extensions 14a, 14b and 14c. The bellows 6 have for their attachment in this slot 14 a plate-shaped on the underside Approach 12 on, as Figure 4 clearly shows. A first Attach bellows to part 8, the plate 12 through the large opening 14d inserted and the bellows 6 in the slot 14 in Figure 6 shifted to the left until the plate 12 the slot 14 snaps into extension 14a. A second bellows 6 is also inserted with his plate 12 through the opening 14d and shifted to the right in FIG. 6 until extension 14c. is only one bellows 6 is provided, this is shown in FIGS moved to extension 14b. The extension 14b thus allows the releasable attachment of a single bellows 6 approximately in the Middle of housing 2.

Zur Drehsicherung besitzt jeder Balg 6 an seinem Boden zwei angeformte Nocken 30, die jeweils in eine Öffnung 25 des Teils 8 eingreifen. Der Teller 12 besitzt mittig einen Durchgang, wie die Figur 2 zeigt. In diesem Durchgang 28 ist ein stutzenförmiger Ansatz eines Nippels 9 einsetzbar. Der Teller 12 ist aus gummielastischem Material wie der übrige Teil des Balges 6 und dichtet den Nippel 9 gegenüber dem Balg 6 ab. Die beiden Nippel 9 sind damit jeweils lösbar und dicht mit einem Balg 6 verbunden.To prevent rotation, each bellows 6 has two molded parts on its base Cam 30, each in an opening 25 of part 8 intervention. The plate 12 has a passage in the middle, such as Figure 2 shows. In this passage 28 is a neck-shaped Approach of a nipple 9 can be used. The plate 12 is out rubber-elastic material like the rest of the bellows 6 and seals the nipple 9 against the bellows 6. The two nipples 9 are each detachably and tightly connected to a bellows 6.

Der Teil 8 weist mehrere nach oben gerichtete elastisch auslenkbare Rastzungen 16 und 22 zur Befestigung des rahmenförmigen Deckels 3 und der Tasten 4 und 5 auf. Die Figur 1 zeigt eine der Rastzungen 16, die mit einer Rastnase in eine Öffnung 15 derRahmenabdeckung 3 eingreift. Vorzugsweise sind mehrere solche Rastzungen 16 am Teil 8 angeformt.The part 8 has several elastically deflectable upward Locking tongues 16 and 22 for fastening the frame-shaped Cover 3 and buttons 4 and 5. Figure 1 shows one of the Locking tongues 16, which have a locking lug in an opening 15 of the frame cover 3 engages. Preferably, there are several such locking tongues 16 molded on part 8.

Die beiden Tasten 4 und 5 sind jeweils haubenförmig ausgebildet und besitzen gemäss Figur 2, hier am Beispiel der Taste 5 gezeigt, eine gewölbte obere Wandung 4b und seitlich nach unten in eine Öffnung 3a der Rahmenabdeckung 3 eingreifende Führungswandung 5a. Die Taste 5 weist eine kleinere Tastfläche auf als die Taste 4, grundsätzlich sind beide Tasten aber ähnlich ausgebildet. Die grössere Taste 4 ist zur Auslösung einer Vollspülung und die kleinere Taste 5 zur Auslösung einer Teilspülung vorgesehen. Die Tasten 4 und 5 sind durch die genannten Rastzungen 22 mit dem Halte- und Führungsteil 8 verschiebbar gelagert und in der oberen Position verrastet. Die Tasten 4 und 5 können in der in den Figuren 1 und 2 gezeigten Position jeweils einzeln nach unten bewegt werden. Die gezeigte obere Position ist durch einen oberen Anschlag bestimmt.The two buttons 4 and 5 are each hood-shaped and according to FIG. 2, shown here using the example of the key 5, a curved upper wall 4b and laterally downwards in an opening 3a of the frame cover 3 engaging guide wall 5a. The key 5 has a smaller key area than that Key 4, but basically both keys are similar. The larger button 4 is for triggering a full flush and the smaller button 5 is provided for triggering a partial rinse. The keys 4 and 5 are by the locking tabs 22nd with the holding and guiding part 8 slidably mounted and in locked in the upper position. Keys 4 and 5 can be used in the in the position shown in Figures 1 and 2 each individually be moved down. The top position shown is by a upper stop determined.

Wie insbesondere die Figur 2 zeigt, übergreifen die Tasten 4 und 5 jeweils einen Balg 6. Der unterhalb der Taste 4 angeordnete Balg ist aus zeichnerischen Gründen weggelassen, ist aber sonst identisch mit dem gezeichneten Balg 6. Bei einer Tastbewegung an einer Taste 4 bzw. 5 wird der jeweilige Balg 6 durch ein unterseitig an der Taste angebrachtes, plattenförmiges Führungsteil 7 geführt. Dieses Führungsteil 7 besitzt einen mittigen Verbindungsteil 31 mit einem unteren Stutzen 21 sowie einem oberen Stutzen 20. Der Stutzen 20 ist in einen Ansatz 32 eingerastet Das gleiche gilt selbstverständlich auch für die Taste 5. Der untere Stutzen 21 greift in einen schlauchförmigen Ansatz 33 des Balges 6 ein und befestigt damit den Balg 6 am Teil 7. Wie die Figur 2 zeigt, liegt der Balg 6 an seinem oberen Ende unterseitig am Teil 7 an und ist an diesem seitlich geführt. Das Teil 7 verhindert somit, dass beim Niederdrücken der Taste 4 das obere Ende des Balges 6 seitlich ausweichen kann.As FIG. 2 in particular shows, the keys 4 overlap and 5 a bellows 6 each. The one arranged below the button 4 Bellows is omitted for drawing reasons, but is otherwise identical to the drawn bellows 6 on a key 4 or 5, the respective bellows 6 by a Plate-shaped guide part attached to the bottom of the button 7 led. This guide part 7 has a central one Connecting part 31 with a lower nozzle 21 and an upper Stub 20. The stub 20 is snapped into an extension 32 The same applies of course to button 5. The lower nozzle 21 engages in a tubular extension 33 of the bellows 6 and thus fastens the bellows 6 to part 7. How FIG. 2 shows, the bellows 6 lies on the underside at its upper end on part 7 and is guided laterally on this. The Part 7 thus prevents that when the button 4 is depressed can deflect the upper end of the bellows 6 laterally.

Die beiden Bälge 6 sind, wie in den Figuren 3 bis 5 gezeigt, vergleichsweise flach mit einem im wesentlichen rechteckigen und seitlich abgerundeten Querschnitt ausgebildet. Zur Stabilisierung weisen die Bälge 6 jeweils seitlich mehrere nach innen gezogene Stützfalten 10 auf. Diese Falten 10a sind an sich übliche Falten 10, jedoch so ausgebildet, dass sie bogenförmig in das Innere des Balges 6 eingreifen. Die Stützfalten 10a ermöglichen, dass der Balg 6 beim Zusammendrücken seine Form im wesentlichen beibehält. Die gezeigte flache Ausbildung der beiden Bälge 6 hat den wesentlichen Vorteil, dass diese in einem rechteckigen Gehäuse 2 wenig Platz beanspruchen und der Innenraum des Gehäuses 2 optimal genutzt wird. Das Gehäuse 2 kann deshalb mit Aussenmassen hergestellt werden, welche den üblichen Tasten entsprechen.As shown in FIGS. 3 to 5, the two bellows 6 are comparatively flat with a substantially rectangular and laterally rounded cross-section. For stabilization the bellows 6 each have a plurality of laterally drawn inwards Support folds 10 on. These folds 10a are usual per se Folds 10, however, so formed that they arcuate into the Intervene inside the bellows 6. The support folds 10a enable that the bellows 6 essentially compresses its shape maintains. The flat design of the two bellows 6 shown has the main advantage that this is in a rectangular housing 2 take up little space and the interior of the housing 2 is used optimally. The housing 2 can therefore have external dimensions be produced, which correspond to the usual keys.

Für die besonders einfache Montage werden die beiden Bälge 6, bzw. lediglich ein Balg 6 am Halte- und Führungsteil 8 befestigt. Nun werden die Mittel eingesetzt und die Leitungen 27 angeschlossen. Auf die Oberseite der Bälge 6 werden nun die Führungsteile 7 aufgesetzt. Nach dem Aufrasten der Tasten 4 und 5 können die miteinander verbundenen Teile in das Gehäuse 2 von oben eingesetzt werden. Schliesslich wird noch die Abdeckung 3 auf den Halterahmen aufgerastet. For particularly simple assembly, the two bellows 6, or only a bellows 6 is attached to the holding and guiding part 8. Now the means are used and the lines 27 are connected. The guide parts are now on the top of the bellows 6 7 put on. After snapping buttons 4 and 5 can the interconnected parts in the housing 2 of be used above. Finally, cover 3 snapped onto the holding frame.

Zur Auslösung einer Spülung wird die Taste 4 oder die Taste 5 gedrückt. Dadurch wird der entsprechende Balg 6 durch das sich nach unten bewegende Führungsteil 7 zusammengedrückt und dadurch wird der Luftdruck in der Kammer 35 erhöht. Dieser Druckimpuls wird über die entsprechende Leitung 27 an eine pneumatische Betätigung eines Spülkastens zur Auslösung einer Spülung weitergegeben. Pneumatische Betätigungen für Spülkästen sind bekannt und brauchen hier deshalb nicht erläutert zu werden. Nach der Betätigung kehrt die entsprechende Taste 4 bzw. 5 infolge der Elastizität des betätigten Balges 6 und des darin herrschenden Luftdrucks in die in den Figuren 1 und 2 gezeigte Grundstellung zurück. Eine separate Feder zur Rückstellung der Tasten 4 und 5 erübrigt sich deshalb.To trigger a rinse, press button 4 or button 5 pressed. As a result, the corresponding bellows 6 through downward moving guide part 7 compressed and thereby the air pressure in the chamber 35 is increased. This pressure pulse is via the corresponding line 27 to a pneumatic actuation a cistern passed to trigger a flush. Pneumatic actuators for cisterns are known and therefore need not be explained here. After actuation returns the corresponding key 4 or 5 due to the elasticity of the actuated bellows 6 and the one prevailing therein Air pressure in the basic position shown in Figures 1 and 2 back. A separate spring to reset buttons 4 and 5 therefore unnecessary.
