Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine BetƤtigungsvorrichtung fĆ¼r eine Auslaufgarnitur nach dem Oberbegriff von Anspruch 1.The present invention relates to an actuating device for an outlet fitting according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus der EP 1 995 386 ist eine gattungsgemƤss BetƤtigungsvorrichtung zur BetƤtigung einer Auslaufgarnitur in einem SpĆ¼lkasten bekannt geworden. Die BetƤtigungsvorrichtung weist ein TastengehƤuse auf, in welchem zwei Tasten gelagert sind. Die Tasten werden dabei bei der SpĆ¼lauslƶsung nach unten bewegt, wobei Ć¼ber diese Bewegung die Auslaufgarnitur zur SpĆ¼lauslƶsung betƤtigt wird.From the EP 1 995 386 is a generic actuator for actuating a spout in a cistern known. The actuating device has a key housing, in which two keys are mounted. The keys are thereby moved downwards during the flushing release, whereby the spout for triggering the flushing action is actuated by this movement.

Obwohl mit der BetƤtigungsvorrichtung nach der EP 1 995 386 ausserordentlich gute Resultate erzielt wurden, kam das BedĆ¼rfnis auf, dass die Tasten bezĆ¼glich des SpĆ¼lkastendeckels ausrichtbar sein sollen, so dass beispielsweise ein auf der Taste aufgedrucktes Logo zum SpĆ¼lkastendeckel ausgerichtet werden kann.Although with the actuator after the EP 1 995 386 Exceptionally good results were obtained, the need arose that the keys should be aligned with respect to the cistern lid, so that, for example, a logo printed on the key to the cistern lid can be aligned.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine BetƤtigungsvorrichtung anzugeben, deren Taste bezĆ¼glich eines SpĆ¼lkastendeckels, in welchem die BetƤtigungsvorrichtung eingebaut wird, ausrichtbar ist.The present invention has for its object to provide an actuator whose key is aligned with respect to a cistern lid, in which the actuator is installed.

Eine solche Aufgabe lƶst die BetƤtigungsvorrichtung nach Anspruch 1. DemgemƤss umfasst eine BetƤtigungsvorrichtung fĆ¼r eine Auslaufgarnitur eines SpĆ¼lkastens ein GehƤuse, das in eine Ɩffnung eines SpĆ¼lkastendeckels einsetzbar ist, mit mindestens einer in diesem GehƤuse entlang einer Achse bewegbar zum GehƤuse gelagerten Taste und ein DrĆ¼ckerelement, welches zur SpĆ¼lauslƶsung durch BetƤtigen der wenigstens einen Taste zur Auslaufgarnitur bewegbar ist. Das GehƤuse umfasst ein MontagegehƤuse, mit welchem die BetƤtigungsvorrichtung mit der Auslaufgarnitur und/oder dem SpĆ¼lkasten verbindbar ist und ein am MontagegehƤuse einstellbar, insbesondere verschwenkbar bzw. verdrehbar, gelagertes TastengehƤuse, wobei am TastengehƤuse die mindestens eine Taste gelagert ist. Mit dem MontagegehƤuse wird die BetƤtigungsvorrichtung im SpĆ¼lkasten gelagert. Das TastengehƤuse ist also zum MontagegehƤuse verschwenkbar bzw. verdrehbar, wodurch die im TastengehƤuse gelagerte Taste ausgerichtet werden kann.Such a problem is solved by the actuating device according to claim 1. Accordingly For example, an actuator for an outlet fitting of a flushing cistern comprises a housing which is insertable into an opening of a cistern lid, with at least one button mounted in this housing along an axis movable to the housing and a pusher element which is movable to SpĆ¼lauslƶsung by pressing the at least one button to Auslaufgarnitur is. The housing comprises a mounting housing, with which the actuating device with the spout and / or the cistern is connectable and adjustable on the mounting housing, in particular pivotable or rotatable, mounted key housing, wherein the at least one key is mounted on the key housing. With the mounting housing, the actuator is mounted in the cistern. The key housing is thus pivotable or rotatable relative to the mounting housing, as a result of which the key mounted in the key housing can be aligned.

Durch die Einstellbarkeit zwischen TastengehƤuse und MontagegehƤuse, lƤsst sich das TastengehƤuse relativ zum MontagegehƤuse einstellen. Somit lƤsst sich die Lage des TastengehƤuse und der Tasten relativ zum SpĆ¼lkastendeckel einstellen. Besonders vorteilhaft ist dies, wenn beispielsweise zwei Tasten vorhanden sind oder wenn ein auf der Taste angeordneter Aufdruck oder eine PrƤgung, wie beispielweise das Logo des Herstellers der BetƤtigungsvorrichtung, ausgerichtet werden soll.Due to the adjustability between key housing and mounting housing, the key housing can be adjusted relative to the mounting housing. Thus, the position of the key housing and the keys can be adjusted relative to the cistern lid. This is particularly advantageous if, for example, two buttons are present or if an imprint or embossment arranged on the button is to be aligned, for example the logo of the manufacturer of the actuating device.

Vorzugsweise steht das TastengehƤuse ausschliesslich Ć¼ber das MontagegehƤuse mit dem SpĆ¼lkasten bzw. der Auslaufgarnitur in Kontakt.Preferably, the key housing is exclusively on the mounting housing with the cistern or the outlet fitting in contact.

Vorzugsweise ist zwischen dem MontagegehƤuse und dem TastengehƤuse eine Kupplung, insbesondere eine Freilaufkupplung mit einer Verzahnung und mindestens einer in die Verzahnung eingreifende Sperrklinke, angeordnet. Die Freilaufkupplung sorgt dafĆ¼r, dass die relative Bewegung zwischen TastengehƤuse und MontagegehƤuse nur in eine Richtung erfolgen kann. In die andere Richtung ist die relative Bewegung zwischen MontagegehƤuse und TastengehƤuse gesperrt, wobei bei einer Einwirkung einer Kraft in diese andere Richtung sowohl das MontagegehƤuse als auch das TastengehƤuse bewegt wird. Die Freilaufkupplung kann auch als Einweg-Kupplung bezeichnet werden.Preferably, between the mounting housing and the key housing, a clutch, in particular a one-way clutch with a toothing and at least one engaging in the toothing pawl arranged. The freewheel clutch ensures that the relative movement between the key housing and mounting housing can only be done in one direction. In the other direction, the relative movement between the mounting housing and key housing is locked, and upon application of a force in this other direction, both the mounting housing and the key housing is moved. The one-way clutch may also be referred to as a one-way clutch.

Die besagte Sperrklinke arbeitet mit der Verzahnung zusammen, wobei die relative Bewegung zwischen MontagegehƤuse und TastengehƤuse in eine Freilaufrichtung, insbesondere nach Ɯberwinden einer durch die Kupplung bereitgestellten Reibungskraft, ermƶglicht wird und wobei die relative Bewegung zwischen MontagegehƤuse und TastengehƤuse in einer zur Freilaufrichtung gegengerichteten Sperrrichtung verunmƶglicht wird. Die Bewegung erfolgt vorzugsweise um die besagte Achse herum.The said pawl cooperates with the toothing, wherein the relative movement between the mounting housing and the key housing in a freewheeling direction, in particular, after overcoming a frictional force provided by the clutch, is made possible and wherein the relative movement between the mounting housing and key housing in a direction of freeance direction opposite locking direction is made impossible. The movement preferably takes place about said axis.

Bei einer Einwirkung einer Bewegung in Sperrrichtung auf die Taste bzw. das TastengehƤuse werden sowohl das TastengehƤuse als auch das MontagegehƤuse gemeinsam bewegt. Bei einer Einwirkung einer Bewegung in Freilaufrichtung kann sich das TastengehƤuse relativ zum MontagegehƤuse bewegen, insbesondere dann, wenn letzteres fest steht.Upon a reverse movement of the button or key housing, both the key housing and the mounting housing are moved together. When exposed to a movement in the freewheeling direction, the key housing can move relative to the mounting housing, especially if the latter is fixed.

Mit anderen Worten gesagt lƤsst die Kupplung bei der Einwirkung einer Bewegung auf das TastengehƤuse in die Freilaufrichtung die Relativbewegung zwischen TastengehƤuse und MontagegehƤuse zu und bei der Einwirkung einer Bewegung auf das TastengehƤuse in die Gegenrichtung, also die Sperrrichtung, wird die Bewegung gesperrt, wobei die Bewegung dann vom TastengehƤuse auf das MontagegehƤuse Ć¼bertragen wird. Hierdurch lƤsst sich einerseits das TastengehƤuse zum MontagegehƤuse ausrichten und andererseits kann auch das MontagegehƤuse mit einer Drehung beaufschlagt werden, welche Drehung beispielsweise fĆ¼r die Trennung der Verbindung zwischen MontagegehƤuse und Auslaufgarnitur einsetzbar ist. FĆ¼r die Montage hingegen stellt die Kupplung eine Reibungskraft bereit, welche dafĆ¼r sorgt, dass auch bei einer Bewegung ein Freilaufrichtung eine Bewegung von TastengehƤuse auf das MontagegehƤuse Ć¼bertragen wird. Wird diese Reibungskraft Ć¼berwunden kommt es zum besagten Freilauf.In other words, the clutch allows the relative movement between the key housing and mounting housing when a movement on the key housing in the freewheeling direction and in the action of a movement on the key housing in the opposite direction, ie the reverse direction, the movement is blocked, wherein the movement then transferred from the key housing to the mounting housing. This allows on the one hand align the key housing to the mounting housing and on the other hand, the mounting housing can be acted upon with a rotation, which rotation can be used for example for the separation of the connection between the mounting housing and outlet fitting. For assembly, however, the clutch provides a frictional force, which ensures that even with a movement of a freewheeling direction, a movement of key housing is transferred to the mounting housing. If this friction force is overcome, it comes to the said freewheel.

Vorzugsweise sind eine Vielzahl von Sperrklinken gleichmƤssig Ć¼ber den Umfang verteilt angeordnet. Die Verzahnung umfasst eine Vielzahl von ZƤhnen, welche ebenfalls gleichmƤssig um den Umfang verteilt angeordnet sind. Die Zahl der ZƤhne ist bevorzugt grƶsser als die Zahl der Sperrklinken.Preferably, a plurality of pawls are arranged uniformly distributed over the circumference. The toothing comprises a plurality of teeth, which are also distributed uniformly around the circumference. The number of teeth is preferably greater than the number of pawls.

Vorzugsweise ist die Verzahnung am MontagegehƤuse und die mindestens eine Sperrklinke am TastengehƤuse angeordnet. Die umgekehrte Anordnung ist aber auch denkbar.Preferably, the teeth on the mounting housing and the at least one pawl on the key housing is arranged. The reverse arrangement is also conceivable.

Vorzugsweise ist die Freilaufrichtung eine Bewegung im Uhrzeigersinn und die Sperrrichtung eine Bewegung im Gegenuhrzeigersinn. Die Drehrichtung definiert sich dabei in Blickrichtung entlang der Achse auf die von aussen sichtbare OberflƤche der Taste von oben. Folglich lƤsst sich also das TastengehƤuse bei einer Bewegung im Uhrzeigersinn zum MontagegehƤuse ausrichten. Bei einer Bewegung im Gegenuhrzeigersinn sperrt die Kupplung und die Bewegung wird vom TastengehƤuse auf das MontagegehƤuse Ć¼bertragen.Preferably, the freewheeling direction is a clockwise movement and the reverse direction is a counterclockwise movement. The direction of rotation defines itself in the direction of view along the axis of the externally visible surface of the button from above. Consequently, so the key housing can be aligned with a movement in a clockwise direction to the mounting housing. In a counterclockwise movement, the clutch disengages and movement is transferred from the key housing to the mounting housing.

In einer Weiterbildung der Erfindung umfasst das MontagegehƤuse eine kreisrunde Grundplatte und eine sich von der Grundplatte entlang einer Mittelachse erstreckenden Seitenwand, wobei die Seitenwand mit einem mindestens teilweise umlaufenden Flansch endet. Der Flansch erstreckt sich vorzugsweise von der Seitenwand nach aussen. Vorzugsweise umfasst das TastengehƤuse eine zylindrische Seitenwand mit einem von der Seitenwand abstehenden Kragenabschnitt.In a further development of the invention, the mounting housing comprises a circular base plate and a side wall extending from the base plate along a central axis, wherein the side wall terminates with an at least partially circumferential flange. The flange preferably extends outwardly from the side wall. Preferably, the key housing comprises a cylindrical side wall having a collar portion projecting from the side wall.

Besonders bevorzugt erstreckt sich der Kragenabschnitt Ć¼ber den Flansch, wobei zwischen Kragenabschnitt und Flansch die Freilaufkupplung angeordnet ist. Der Kragenabschnitt deckt also den Flanschabschnitt ab, wodurch dieser von ausserhalb nicht sichtbar ist.Particularly preferably, the collar portion extends over the flange, wherein between the collar portion and the flange, the overrunning clutch is arranged. The collar portion thus covers the flange portion, whereby this is not visible from outside.

Vorzugsweise stellen die Grundplatte und die Seitenwand des MontagegehƤuses einen Innenraum bereit, in welchem das TastengehƤuse mindestens teilweise einragt. Folglich wird also das TastengehƤuse im Innenraum des MontagegehƤuses gelagert.Preferably, the base plate and the side wall of the mounting housing provide an interior, in which the key housing at least partially protrudes. Consequently, therefore, the key housing is mounted in the interior of the mounting housing.

Vorzugsweise ist das TastengehƤuse im MontagegehƤuse verdrehbar gelagert, wobei zwischen TastengehƤuse und MontagegehƤuse ein Sicherungselement vorgesehen ist, welches eine axiale Verschiebung zwischen TastengehƤuse und MontagegehƤuse verhindert. Das Sicherungselement kann verschiedenartig ausgebildet sein. Besonders bevorzugt ist es eine Nut- und Kamm-Verbindung, wobei der Kamm in die Nut einragt.Preferably, the key housing is rotatably mounted in the mounting housing, wherein a fuse element is provided between the key housing and mounting housing, which prevents axial displacement between the key housing and mounting housing. The securing element can be designed in various ways. Particularly preferably, it is a groove and comb connection, wherein the comb protrudes into the groove.

Vorzugsweise wird die mindestens eine Taste mit einem RĆ¼ckstellelement, insbesondere einer Druckfeder, in der Ausgangsstellung gehalten, wobei das RĆ¼ckstellelement vorzugsweise zwischen Grundplatte und Taste gelagert ist.Preferably, the at least one key is held with a return element, in particular a compression spring in the initial position, wherein the return element is preferably mounted between the base plate and key.

In einer Weiterbildung der Erfindung umfasst das MontagegehƤuse ein Gewindeabschnitt mit einem Gewinde, insbesondere mit einem Aussengewinde, mit welchem Gewinde das MontagegehƤuse mit einer Auslaufgarnitur verbindbar ist.In a further development of the invention, the mounting housing comprises a threaded portion with a thread, in particular with an external thread, with which thread the mounting housing can be connected to an outlet fitting.

Vorzugsweise ist die Steigungsrichtung des Gewindes des Gewindeabschnittes gleich der Freilaufrichtung der Kupplung. Bei einem rechtsgƤngigen Gewinde ist die Freilaufrichtung im Uhrzeigersinn und die Sperrrichtung im Gegenuhrzeigersinn. Bei einem linksgƤngigen Gewinde umgekehrt. Dies bewirkt, dass wenn die Kupplung die Relativbewegung zwischen MontagegehƤuse und TastengehƤuse sperrt, eine Drehung auf die beiden GehƤuse die Trennung zwischen Gewinde und Auslaufgarnitur ermƶglicht wird. Der Gewindeabschnitt kann also aus dem GegenstĆ¼ck in der Auslaufgarnitur heraus gedreht werden. Weiter wird bewirkt, dass wenn die Kupplung die Relativbewegung zwischen MontagegehƤuse und TastengehƤuse zulƤsst die Montage zwischen Gewinde und Auslaufgarnitur herstellbar ist. Bei der Montage wird dabei die Kraft vom TastengehƤuse Ć¼ber die in der Kupplung vorliegende Reibung auf das MontagegehƤuse Ć¼bertragen und sobald das Gewinde bei der Auslaufgarnitur eingeschraubt ist, kommt es zu einem Durschleifen der Kupplung, so dass noch die Lage des TastengehƤuses relativ zum mittlerweile feststehenden MontagegehƤuse einstellbar wird.Preferably, the pitch direction of the thread of the threaded portion is equal to the freewheeling direction of the clutch. In a right-handed thread, the freewheeling direction is clockwise and the reverse direction counterclockwise. With a left-handed thread reversed. This causes that when the coupling locks the relative movement between the mounting housing and key housing, a rotation on the two housings, the separation between the thread and outlet fitting is made possible. The threaded portion can therefore be rotated out of the counterpart in the outlet fitting. Furthermore, it is ensured that when the coupling permits the relative movement between the mounting housing and the key housing, the assembly between the thread and the outlet fitting can be produced. During assembly, the force is transferred from the key housing on the present in the clutch friction on the mounting housing and once the thread is screwed in the outlet fitting, there is a major grinding of the clutch, so that still the position of the key housing relative to the now fixed mounting housing becomes adjustable.

BESCHREIBUNG BEVORZUGTER AUSFƜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In der Figur 1 wird eine BetƤtigungsvorrichtung 1 fĆ¼r eine Auslaufgarnitur 9 eines SpĆ¼lkastens gezeigt. Der SpĆ¼lkasten und die Auslaufgarnitur 9 sind im Wesentlichen aus dem Stand der Technik bekannt. Mit der BetƤtigungsvorrichtung 1 kann eine Kraft bzw. eine Bewegung auf die Auslaufgarnitur 9 bereitgestellt werden, welche dann zur SpĆ¼lauslƶsung fĆ¼hrt. Bei SpĆ¼lauslƶsung wird ein Ventilkƶrper der Auslaufgarnitur 9 von einem Ventil am SpĆ¼lkasten angehoben und das Wasser kann Ć¼ber dieses Ventil aus dem SpĆ¼lkasten zu einer Toilette oder einem Urinal abfliessen.In the FIG. 1 an actuator 1 is shown for a spout 9 a cistern. The cistern and the spout 9 are essentially known from the prior art. With the actuating device 1, a force or a movement can be provided to the outlet fitting 9, which then leads to SpĆ¼lauslƶsung. When SpĆ¼lauslƶsung a valve body of the spout 9 is raised by a valve on the cistern and the water can flow through this valve from the cistern to a toilet or urinal.

Die BetƤtigungsvorrichtung 1 umfasst ein GehƤuse 2, das in eine Ɩffnung 3 eines SpĆ¼lkastendeckels 4 einsetzbar ist. Weiter umfasst die BetƤtigungsvorrichtung mindestens eine in diesem GehƤuse 2 entlang einer Achse M bewegbar zum GehƤuse 2 gelagerte Taste 5. Ɯber die Taste 5 kann die besagte Bewegung zur Auslƶsung der SpĆ¼lung auf die Auslaufgarnitur 9 bereitgestellt werden. Der Benutzer bewegt dabei die Taste 5 von Hand. In besonders bevorzugten AusfĆ¼hrungsformen sind zwei Tasten, nƤmlich eine TeilmengenspĆ¼ltaste und eine VollmengenspĆ¼ltaste vorhanden. Weiter umfasst die Auslaufgarnitur 9 ein DrĆ¼ckerelement 6, welches zur SpĆ¼lauslƶsung durch BetƤtigen der wenigstens einen Taste 5 bezĆ¼glich der Auslaufgarnitur 9 und bezĆ¼glich des GehƤuses 2 bewegbar ist. Ɯber das DrĆ¼ckerelement 6 wird die SpĆ¼lung durch die Auslaufgarnitur 9 in bekannter Weise ausgelƶst.The actuating device 1 comprises a housing 2 which can be inserted into an opening 3 of a cistern lid 4. Furthermore, the actuating device comprises at least one button 5 movably mounted in this housing 2 along an axis M to the housing 2. Via the button 5, said movement for triggering the flushing onto the outlet fitting 9 can be provided. The user moves the key 5 by hand. In particularly preferred embodiments, there are two keys, namely a subset purge key and a full rate purge key. Furthermore, the outlet fitting 9 comprises a pusher element 6, which is movable for purging by operating the at least one button 5 with respect to the outlet fitting 9 and with respect to the housing 2. About the trigger element 6, the flushing is triggered by the outlet fitting 9 in a known manner.

In der Figur 1 wird die BetƤtigungsvorrichtung 1 in einer Montageposition gezeigt. Ɯber eine Drehung D um die Mittelachse M kann die BetƤtigungsvorrichtung 1 mit dem Gewinde 21 mit der Auslaufgarnitur 9 verbunden werden. Beim Gewinde handelt es sich vorzugsweise um ein Gewinde mit rechtsgƤngiger Steigung 25, so dass Ć¼ber eine Bewegung im Uhrzeigersinn die BetƤtigungsvorrichtung eingeschraubt werden kann.In the FIG. 1 the actuator 1 is shown in a mounting position. About a rotation D about the central axis M, the actuator 1 can be connected to the thread 21 with the outlet fitting 9. The thread is preferably a thread with a right-hand pitch 25, so that the actuator can be screwed by a movement in a clockwise direction.

In der Figur 2 wird die BetƤtigungsvorrichtung 1 in der montierten Stellung gezeigt. Hier liegt die BetƤtigungsvorrichtung 1 in der Ɩffnung 3 des SpĆ¼lkastendeckels 4 und steht zudem mit der OberflƤche 23 des SpĆ¼lkastendeckels 4 in Kontakt. Mit einem Kragenabschnitt 17 Ć¼berragt die BetƤtigungsvorrichtung die Ɩffnung 3 und sichert so den SpĆ¼lkastendeckel 4 zum SpĆ¼lkasten.In the FIG. 2 the actuator 1 is shown in the assembled position. Here the actuator 1 is located in the opening 3 of the cistern lid 4 and is also in contact with the surface 23 of the cistern lid 4. With a collar portion 17, the actuating device projects beyond the opening 3 and thus secures the cistern lid 4 to the cistern.

In der Figur 3 wird eine Schnittdarstellung durch die Mittelachse M der BetƤtigungsvorrichtung 1 gezeigt. Hier kann gut erkannt werden, dass das GehƤuse 2 ein MontagegehƤuse 7 und ein TastengehƤuse 8 umfasst. Mit dem MontagegehƤuse 7 wird die BetƤtigungsvorrichtung 1 mit der Auslaufgarnitur 9 bzw. dem SpĆ¼lkastendeckel 4 verbunden. Das MontagegehƤuse 7 steht also mit dem SpĆ¼lkastendeckel 4 bzw. mit der Auslaufgarnitur 9 in Kontakt. Das TastengehƤuse 8 ist am bzw. im MontagegehƤuse 7 einstellbar gelagert. In der vorliegenden AusfĆ¼hrungsform ist das TastengehƤuse 8 zum MontagegehƤuse 7 um die Mittelachse M verschwenkt bzw. verdrehbar. Am TastengehƤuse 8 ist die mindestens eine Taste 5 gelagert.In the FIG. 3 a sectional view through the central axis M of the actuator 1 is shown. Here it can be well recognized that the housing 2 comprises a mounting housing 7 and a key housing 8. With the mounting housing 7, the actuator 1 is connected to the outlet fitting 9 and the cistern lid 4. The mounting housing 7 is thus in contact with the cistern lid 4 or with the outlet fitting 9. The key housing 8 is mounted on or in the mounting housing 7 adjustable. In the present embodiment, the key housing 8 is pivoted to the mounting housing 7 about the central axis M or rotatable. At the key housing 8, the at least one key 5 is mounted.

Zwischen dem MontagegehƤuse 7 und dem TastengehƤuse 8 ist eine Kupplung 10 vorhanden. Die Kupplung 10 ist vorzugsweise eine Freilaufkupplung 10 mit einer Verzahnung 11 und mit mindestens einer in die Verzahnung 11 eingreifende Sperrklinke 12. Die Freilaufkupplung 10 kann auch als Einweg-Kupplung bezeichnet werden.Between the mounting housing 7 and the key housing 8, a clutch 10 is present. The clutch 10 is preferably an overrunning clutch 10 with a toothing 11 and with at least one engaging in the toothing 11 pawl 12. The overrunning clutch 10 may also be referred to as a one-way clutch.

Die Verzahnung 11 und die Sperrklinke 12 werden in den Figuren 4 und 5 entsprechend gezeigt. Die Kupplung hat die Funktion, das bei einer Einwirkung einer Bewegung auf das TastengehƤuse 8 in eine erste Richtung oder Freilaufrichtung, hier im Uhrzeigersinn UZ, die Relativbewegung zwischen TastengehƤuse 8 und MontagegehƤuse 7 zugelassen wird. Die Relativbewegung wird insbesondere nach Ɯberwinden der durch die Verzahnung 11 und Sperrklinke 12 bereitgestellten Reibungskraft zugelassen. Der eigentliche Freilauf setzt also erst dann ein, wenn eine genĆ¼gend grosse Kraft zwischen TastengehƤuse 8 und MontagegehƤuse 7 wirkt und die Sperrklinke 12 aus der Verzahnung 11 bewegt wird. Folglich kann der Installateur bei einer Drehung in Freilaufrichtung die Lage des TastengehƤuses 8 zum MontagegehƤuse 7 einstellen. Bei der Einwirkung einer Bewegung auf das TastengehƤuse 8 in eine zweite Richtung entgegen der ersten Richtung, hier mit GUZ angegeben, wird die Relativbewegung zwischen TastengehƤuse 8 und MontagegehƤuse 7 nicht zugelassen bzw. gesperrt. Die zweite Richtung kann dabei als Sperrrichtung bezeichnet werden. Folglich wird die Bewegung vom TastengehƤuse 8 auf das MontagegehƤuse 7 entsprechend Ć¼bertragen.The teeth 11 and the pawl 12 are in the FIGS. 4 and 5 shown accordingly. The coupling has the function that is permitted in a first direction or freewheeling direction, here in a clockwise direction UZ, the relative movement between the key housing 8 and mounting housing 7 in an action of a movement on the key housing 8. The relative movement is allowed in particular after overcoming the friction provided by the teeth 11 and pawl 12. The actual freewheel thus only sets in when a sufficiently large force acts between the key housing 8 and mounting housing 7 and the pawl 12 is moved out of the toothing 11. Consequently, the installer can adjust the position of the key housing 8 to the mounting housing 7 with a rotation in the freewheeling direction. Upon the action of a movement on the key housing 8 in a second direction opposite to the first direction, indicated here with GUZ, the relative movement between the key housing 8 and mounting housing 7 is not allowed or blocked. The second direction can be as Reverse direction can be called. Consequently, the movement is transmitted from the key housing 8 to the mounting housing 7 accordingly.

Von der Figur 4 kann erkannt werden, dass eine Vielzahl von Sperrklinken 12 gleichmƤssig Ć¼ber den Umfang verteilt angeordnet sind. In der vorliegenden AusfĆ¼hrungsform sind zwƶlf Sperrklinken 12 angeordnet. Es ist aber auch denkbar, weniger oder mehr als zwƶlf Sperrklinken 12 anzuordnen. Die Verzahnung 11 weist eine Vielzahl von ZƤhnen auf, welche ebenfalls in regelmƤssigen AbstƤnden um den Umfang des MontagegehƤuses 7 verteilt angeordnet sind. Je feiner die Aufteilung der ZƤhne der Verzahnung 11, desto genauer kann die Lage der Taste 5 bzw. des TastengehƤuses 8 zum MontagegehƤuse 7 eingestellt werden.Of the FIG. 4 can be seen that a plurality of pawls 12 are arranged distributed uniformly over the circumference. In the present embodiment, twelve pawls 12 are arranged. But it is also conceivable to arrange less than or more than twelve pawls 12. The toothing 11 has a plurality of teeth, which are also distributed at regular intervals around the circumference of the mounting housing 7. The finer the division of the teeth of the toothing 11, the more accurate the position of the key 5 and the key housing 8 can be adjusted to the mounting housing 7.

Die Verzahnung 11 ist also vorzugweise am MontagegehƤuse 7 und die mindestens eine Sperrklinke 12 ist vorzugweise am TastengehƤuse 8 angeordnet. Die Anordnung kann aber auch vertauscht werden.The toothing 11 is thus preferably on the mounting housing 7 and the at least one pawl 12 is preferably arranged on the key housing 8. The arrangement can also be reversed.

Die Freilaufrichtung UZ ist vorzugsweise eine Bewegung im Uhrzeigersinn und die Sperrrichtung GUZ ist vorzugweise eine Bewegung im Gegenuhrzeigersinn. Die Bewegungen kƶnnen aber auch gegengerichtet sein.The freewheeling direction UZ is preferably a clockwise movement and the reverse direction GUZ is preferably a counterclockwise movement. The movements can also be counter-directed.

Von der Figur 3 kann erkannt werden, dass das MontagegehƤuse 7 eine kreisrunde Grundplatte 13 und eine sich von der Grundplatte 13 entlang einer Mittelachse M erstreckenden Seitenwand 14 umfasst. Die Seitenwand 14 endet hier mit einem Flansch 15, welcher mindestens teilweise um die Mittelachse M umlaufend angeordnet ist. Vorzugweise verlƤuft der Flansch 15 vollstƤndig um die Mittelachse M herum. Grundplatte 13 und Seitenwand 14 definieren einen Innenraum 18.Of the FIG. 3 It can be seen that the mounting housing 7 comprises a circular base plate 13 and a side wall 14 extending from the base plate 13 along a central axis M. The side wall 14 ends here with a flange 15, which is at least partially arranged circumferentially around the central axis M. Preferably, the flange 15 extends completely around the central axis M around. Base plate 13 and side wall 14 define an interior space 18.

Das TastengehƤuse 8 umfasst in der vorliegenden AusfĆ¼hrungsform eine zylindrische Seitenwand 16, die einen von der Seitenwand 16 abstehenden Kragenabschnitt 17 umfasst. Die Seitenwand 16 begrenzt einen Innenraum 24, in welchem die Taste 5 gelagert ist. Die Taste 5 ist beweglich im Innenraum entlang der Mittelachse M gelagert. Weiter steht die Taste 5 drehfest zum TastengehƤuse 8. Eine Drehung auf die Taste 5 wirkt sich also in einer Drehung des TastengehƤuses 8 aus. Hierzu steht die Taste 5 Ć¼ber geeignete Mittel, wie FĆ¼hrungselemente, mit dem TastengehƤuse 8 in Verbindung.The key housing 8 in the present embodiment comprises a cylindrical side wall 16 which includes a collar portion 17 projecting from the side wall 16. The side wall 16 defines an interior 24 in which the key 5 is mounted. The button 5 is movably mounted in the interior along the central axis M. Next, the key 5 rotatably to the key housing 8. A rotation on the key 5 thus affects in a rotation of the key housing 8. For this purpose, the button 5 via suitable means, as guide elements, with the key housing 8 in conjunction.

Von der Figur 3 kann erkannt werden, dass der Kragenabschnitt 17 des TastengehƤuses 8 sich Ć¼ber den Flansch 15 des MontagegehƤuses 7 erstreckt. Die besagte Kupplung 10, insbesondere die Freilaufkupplung 10, ist dabei zwischen dem Kragenabschnitt 17 und dem Flansch 15 angeordnet. In anderen AusfĆ¼hrungsformen kann die Kupplung aber auch an anderen Orten angeordnet werden. Hier ist die Verzahnung 10 an der Aussenseite des Flansches 15 angeordnet und die Sperrklinken 12 sind an der Innenseite des Kragenabschnittes 17 angeordnet.Of the FIG. 3 can be seen that the collar portion 17 of the key housing 8 extends over the flange 15 of the mounting housing 7. The said clutch 10, in particular the one-way clutch 10, is arranged between the collar portion 17 and the flange 15. In other embodiments, however, the coupling can also be arranged in other locations. Here, the toothing 10 is arranged on the outside of the flange 15 and the pawls 12 are arranged on the inside of the collar portion 17.

Durch die Ɯberdeckung des Flansches 15 mit dem Kragenabschnitt 17 kann der Flansch 15 von aussen her nicht erkannt werden, so wie dies in der Figur 2 gezeigt wird. Der Benutzer sieht von aussen nur den Kragenabschnitt 17 und die Taste 5.Due to the overlap of the flange 15 with the collar portion 17, the flange 15 can not be recognized from the outside, as shown in the FIG. 2 will be shown. The user sees from outside only the collar portion 17 and the key 5.

Das TastengehƤuse 8 ragt mindestens teilweise in den Innenraum 18 des MontagegehƤuses 7 ein. Mit anderen Worten kann gesagt werden, dass das TastengehƤuse 8 im MontagegehƤuse 7 gelagert ist. Die Lagerung ist dabei verdreh- bzw. verschwenkbar ausgebildet, so dass das TastengehƤuse 8 zum MontagegehƤuse 7 um die Mittelachse herum verdreht bzw. verschwenkt werden kann. In der vorliegenden AusfĆ¼hrungsform ist zwischen dem TastengehƤuse 8 und dem MontagegehƤuse 7 ein Sicherungselement 19 vorgesehen, welches eine axiale Verschiebung zwischen TastengehƤuse 8 und MontagegehƤuse 7 verhindert. Das Sicherungselement 19 hat hier die Gestalt einer Nut- und Kammverbindung, wobei die Nut sich in die Seitenwand 14 des MontagegehƤuses 7 hineinerstreckt und wobei sich der Kamm von der Seitenwand 16 des TastengehƤuses 8 weg erstreckt. Andere Verbindungsarten sind selbstverstƤndlich ebenfalls denkbar.The key housing 8 projects at least partially into the interior 18 of the mounting housing 7. In other words, it can be said that the key housing 8 is mounted in the mounting housing 7. The bearing is rotatable or pivotable, so that the key housing 8 can be rotated or pivoted to the mounting housing 7 around the central axis. In the present embodiment, a securing element 19 is provided between the key housing 8 and the mounting housing 7, which prevents axial displacement between the key housing 8 and mounting housing 7. The securing element 19 here has the shape of a groove and comb connection, wherein the groove extends into the side wall 14 of the mounting housing 7 and wherein the comb of the side wall 16 of the key housing 8 extends away. Of course, other types of connections are also conceivable.

Die vorliegende AusfĆ¼hrungsform der BetƤtigungsvorrichtung 1 umfasst zudem ein RĆ¼ckstellelement 20, mit welchem die mindestens eine Taste 5 in der Ausgangstellung gehalten wird bzw. von der SpĆ¼lstellung in die Ausgangsstellung zurĆ¼ck bewegt wird. Das RĆ¼ckstellelement 20 ist vorzugsweise zwischen Grundplatte 13 und Taste 5 angeordnet. Hier hat das RĆ¼ckstellelement 20 die Gestalt einer Druckfeder.The present embodiment of the actuating device 1 also comprises a return element 20, with which the at least one key 5 is held in the initial position or is moved back from the flushing position to the starting position. The restoring element 20 is preferably arranged between base plate 13 and button 5. Here, the return element 20 has the shape of a compression spring.

Das MontagegehƤuse 7 umfasst weiter einen Gewindeabschnitt 21 mit einem Gewinde, der sich hier von der Grundplatte 13 des MontagegehƤuses 7 entlang der Mittelachse M gegenĆ¼ber dem Innenraum 18 wegerstreckt. Der Gewindeabschnitt 21 umfasst ein Aussengewinde und eine sich entlang der Mittelachse erstreckende Ɩffnung 26, in welcher das DrĆ¼ckerelement 6 bewegbar gelagert ist. Mit dem Gewindeabschnitt 21 lƤsst sich das MontagegehƤuse 7 mit der Auslaufgarnitur 9 verbinden, so wie dies in den Figuren 1 und 2 gezeigt ist. Hierzu weist die Auslaufgarnitur 9 ebenfalls ein passendes Gewinde auf.The mounting housing 7 further comprises a threaded portion 21 with a thread, the extends here from the base plate 13 of the mounting housing 7 along the central axis M with respect to the interior 18 wegerstreckt. The threaded portion 21 comprises an external thread and an opening 26 extending along the central axis, in which the pusher element 6 is movably mounted. With the threaded portion 21, the mounting housing 7 can connect to the outlet fitting 9, as in the Figures 1 and 2 is shown. For this purpose, the outlet fitting 9 also has a matching thread.

Das Gewinde 25 weist eine Steigungsrichtung auf, welche gleich der Freilaufrichtung gerichtet ist. Bei einem rechtsgƤngigen Gewinde ist die Freilaufrichtung im Uhrzeigersinn und die Sperrrichtung im Gegenuhrzeigersinn. Die Montage wird also bei einer Drehung im Uhrzeigersinn erfolgen, wobei die Drehbewegung Ć¼ber das TastengehƤuse 8 auf das MontagegehƤuse 7 Ć¼bertragen wird, bis die besagte Reibungskraft der Kupplung 10 Ć¼berwunden wird. FĆ¼r die Demontage heisst dies, dass wenn die Kupplung 10 die Relativbewegung zwischen MontagegehƤuse 7 und TastengehƤuse 8 sperrt eine Drehung auf die beiden GehƤuse 7, 8 eine Trennung zwischen Gewinde 21 und Auslaufgarnitur 9 ermƶglicht wird. Mit einem linksgƤngigen Gewinde, was ebenfalls einsetzbar wƤre, sind die Drehrichtungen entsprechend umgekehrt.The thread 25 has a pitch direction, which is directed equal to the freewheeling direction. In a right-handed thread, the freewheeling direction is clockwise and the reverse direction counterclockwise. The assembly will thus take place in a clockwise rotation, wherein the rotational movement is transmitted via the key housing 8 on the mounting housing 7 until said frictional force of the clutch 10 is overcome. For disassembly this means that when the clutch 10, the relative movement between the mounting housing 7 and key housing 8 blocks rotation on the two housings 7, 8 a separation between the thread 21 and outlet fitting 9 is possible. With a left-handed thread, which could also be used, the directions of rotation are reversed accordingly.

Die Taste 5 steht mit dem DrĆ¼ckerelement 6 Ć¼ber eine KontaktflƤche 22 in Verbindung. Die KontaktflƤche 22 ist dabei senkrecht zur Mittelachse M orientiert, so dass die Taste 5 relativ zum DrĆ¼ckerelement 6 bei der Einstellung der Lage der Taste 5 bewegt werden kann.The button 5 is connected to the pusher element 6 via a contact surface 22 in connection. The contact surface 22 is oriented perpendicular to the central axis M, so that the key 5 can be moved relative to the pusher element 6 in the adjustment of the position of the key 5.
