Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Betätigungseinheit für eine Betätigungsvorrichtung einer Spüleinrichtung nach dem Oberbegriff von Anspruch 1.The present invention relates to an actuating unit for an actuating device of a flushing device according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Eine Betätigungsplatte dieser Art ist im Stand der Technik aus der EP 2 045 405 des Anmelders bekannt geworden. Die bekannte Betätigungsplatte umfasst eine Lagerplatte mit wenigstens einem Betätigungselement, welches zur feststehenden Lagerplatte verschwenkbar ist. Das Betätigungselement ist über ein Federelement mit der Lagerplatte verbunden. Das Federelement wird über eine Heissniete mit der Lagerplatte und dem Betätigungselement verbunden. Mit der Heissniete kann eine sehr gute und auch langlebige Verbindung zwischen Lagerplatte und Betätigungselement erreicht werden.An actuator plate of this type is known from the prior art EP 2 045 405 of the applicant. The known actuating plate comprises a bearing plate with at least one actuating element which can be pivoted relative to the fixed bearing plate. The actuating element is connected to the bearing plate via a spring element. The spring element is connected to the bearing plate and the actuating element via a hot rivet. A very good and long-lasting connection between the bearing plate and the actuating element can be achieved with the hot rivet.

Allerdings ist der Vorgang des Erhitzens und des lokalen Aufschmelzens der Heissniete während der Herstellung nachteilig, weil dieser Vorgang relativ viel Zeit in Anspruch nimmt. Zudem ist der Prozess schwierig zu überwachen.However, the process of heating and locally melting the hot rivets during production is disadvantageous because this process takes a relatively long time. The process is also difficult to monitor.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Der Erfindung liegt nun eine Aufgabe zugrunde, eine Betätigungseinheit anzugeben, welche die Nachteile des Standes der Technik überwindet. Insbesondere soll die Herstellung der Betätigungseinheit vereinfacht werden.The invention is based on an object of specifying an actuating unit which overcomes the disadvantages of the prior art. In particular, the manufacture of the actuation unit is to be simplified.

Diese Aufgabe löst eine Betätigungseinheit nach Anspruch 1. Eine Betätigungseinheit für die Betätigung einer Spüleinrichtung umfasst eine Lagerplatte, mindestens ein relativ zur Lagerplatte bewegbares Betätigungselement und mindestens ein gefedert ausgebildetes Lagerelement, das mit einem ersten Ende mit der Lagerplatte und mit einem zweiten Ende mit dem mindestens einen Betätigungselement verbunden ist. Das Lagerelement steht mit mindestens einem der beiden Enden über eine formschlüssige und/oder kraftschlüssige Verbindung mit der Lagerplatte und/oder dem Betätigungselement in Verbindung.An actuating unit for actuating a flushing device comprises a bearing plate, at least one relative to the actuating unit Bearing plate movable actuating element and at least one spring-mounted bearing element which is connected at a first end to the bearing plate and at a second end to the at least one actuating element. The bearing element is connected to at least one of the two ends via a positive and / or non-positive connection with the bearing plate and / or the actuating element.

Aufgrund der Verbindung über die formschlüssige und/oder kraftschlüssige Verbindung zwischen dem Lagerelement und der Lagerplatte bzw. dem Betätigungselement kann eine einfach herstellbare Verbindung geschaffen werden. Dies insbesondere unter der Massgabe, dass die Vorteile des gefederten Lagerelementes, nämlich insbesondere dessen Langlebigkeit, erhalten bleiben.Because of the connection via the positive and / or non-positive connection between the bearing element and the bearing plate or the actuating element, a connection that is easy to produce can be created. This, in particular, provided that the advantages of the spring-loaded bearing element, namely in particular its durability, are retained.

Darüber hinaus ist die Verbindung einfacher dimensionierbar und effizienter herstellbar.In addition, the connection is easier to dimension and more efficient to produce.

Vorzugsweise ist die besagte Verbindung ausschliesslich formschlüssig und/oder kraftschlüssig. Die besagte Verbindung ist demnach nicht stoffschlüssig.Said connection is preferably exclusively positive and / or non-positive. The said connection is therefore not cohesive.

Insbesondere wird die besagte Verbindung ohne thermische Einwirkung auf die Lagerplatte und/oder das Betätigungselement hergestellt. Folglich wird die Verbindung nicht durch eine Materialverformung negativ beeinflusst.In particular, said connection is made without thermal action on the bearing plate and / or the actuating element. Consequently, the connection is not adversely affected by material deformation.

Vorzugsweise ist die besagte Verbindung eine mechanische Schnappverbindung mit einer Aufnahme und einem Schnappkörper. Der Schnappkörper ist in die Aufnahme einschiebbar und wird in der Aufnahme formschlüssig und/oder kraftschlüssig gehalten.Said connection is preferably a mechanical snap connection with a receptacle and a snap body. The snap body can be inserted into the receptacle and is held in the receptacle in a positive and / or non-positive manner.

Das mindestens eine Lagerelement stellt vorzugsweise die einzige mechanische Verbindung zwischen Lagerplatte und Betätigungselement bereit. Das Lagerelement bildet ein Gelenk, mit welchem das Betätigungselement zur Lagerplatte verschwenkbar ist. Das Lagerelement ist vorzugsweise als Blattfeder ausgebildet.The at least one bearing element preferably provides the only mechanical connection between the bearing plate and the actuating element. The bearing element forms a joint with which the actuating element can be pivoted to the bearing plate. The bearing element is preferably designed as a leaf spring.

Die Zuordnung von Aufnahme und Schnappkörper kann beliebig sein. Das heisst die Aufnahme kann sowohl an der Lagerplatte und/oder dem Betätigungselement angeordnet sein oder sie kann auch Teil des Lagerelementes sein. Die Aufnahme ist vorzugsweise einstückig und integral mit der Lagerplatte und/oder mit dem Betätigungselement ausgebildet. Bezüglich der Zuordnung und der Ausbildung kann gleiches für den Schnappkörper gelten.The assignment of receptacle and snap body can be arbitrary. This means that the receptacle can be arranged both on the bearing plate and / or the actuating element or it can also be part of the bearing element. The inclusion is preferred integrally and integrally formed with the bearing plate and / or with the actuating element. With regard to the assignment and the training, the same can apply to the snap body.

Bei der ersten Variante ist die Aufnahme also vorzugsweise am Betätigungselement und/oder an der Lagerplatte angeordnet. Gerade wenn die Lagerplatte und das Betätigungselement mit einem Spritzgiessverfahren hergestellt werden, kann die Aufnahme sehr einfach hergestellt werden.In the first variant, the receptacle is therefore preferably arranged on the actuating element and / or on the bearing plate. Especially when the bearing plate and the actuating element are produced using an injection molding process, the holder can be produced very easily.

In einer zweiten Variante der Schnappverbindung ist die Aufnahme Teil des mindestens einen Endes des Lagerelementes und der Schnappkörper ist an der Lagerplatte und/oder dem Betätigungselement angeformt.In a second variant of the snap connection, the receptacle is part of the at least one end of the bearing element and the snap body is molded onto the bearing plate and / or the actuating element.

Das Lagerelement ist entlang einer Steckrichtung mit der Lagerplatte und/oder dem Betätigungselement verbindbar. Das Lagerelement und/oder die Lagerplatte bzw. das Betätigungselement verfügen über mindestens ein gefedert ausgebildetes Anschlagselement, welches eine Bewegung gegen die Steckrichtung verhindert.The bearing element can be connected to the bearing plate and / or the actuating element along a plug-in direction. The bearing element and / or the bearing plate or the actuating element have at least one spring-loaded stop element which prevents movement against the direction of insertion.

Die Steckrichtung erstreckt sich vorzugsweise entlang einer Geraden oder ist mindestens abschnittsweise gekrümmt.The insertion direction preferably extends along a straight line or is curved at least in sections.

Während des Steckvorgangs kann es aufgrund der federnden Eigenschaften des Lagerteils zu einer federnden Verformung desselben kommen, was die Montage begünstigt.During the plug-in process, the resilient properties of the bearing part can result in a resilient deformation thereof, which favors assembly.

Vorzugsweise ist das Anschlagselement als Federlasche ausgebildet, welche im verbundenen Zustand in eine Ausnehmung einragt und in der Ausnehmung mit einer Flanke in Kontakt kommt.The stop element is preferably designed as a spring tab which, when connected, protrudes into a recess and comes into contact with a flank in the recess.

Die Flanke ist vorzugsweise winklig zur Steckrichtung geneigt. Die winklige Neigung ist vorzugsweise derart, dass bei Auftreten einer Kraft entgegen der Steckrichtung die Bewegung der Federlasche in der Ausnehmung blockiert wird oder die Federlasche tiefer in die Ausnehmung einfährt.The flank is preferably inclined at an angle to the direction of insertion. The angled slope is preferably in such a way that when a force occurs counter to the direction of insertion, the movement of the spring clip is blocked in the recess or the spring clip moves deeper into the recess.

In einer zweiten Ausführung ist die Federlasche Teil der Lagerplatte und/oder des Betätigungselements und die Ausnehmung ist Teil des Lagerelementes.In a second embodiment, the spring tab is part of the bearing plate and / or the actuating element and the recess is part of the bearing element.

Die besagte Aufnahme umfasst Begrenzungsbereiche zur Sicherung des Lagerteils. Die Aufnahme ist mit den Begrenzungsbereichen vorzugsweise derart ausgebildet, dass diese die Bewegung des Lagerteils in alle Richtungen ausser in die Richtung gegen die Steckrichtung einschränkt. Die Bewegung gegen die Steckrichtung wird durch das Anschlagselement gesichert.The said recording includes boundary areas for securing the bearing part. The receptacle is preferably designed with the delimitation areas in such a way that it restricts the movement of the bearing part in all directions except in the direction opposite to the plugging direction. The movement against the direction of insertion is secured by the stop element.

Mit anderen Worten gesagt sind die Begrenzungsbereiche, insbesondere derart angeordnet sind, dass sie eine Bewegung des Lagerelementes in der Aufnahme quer zur Steckrichtung verhindern. Die Begrenzungsbereiche sind beispielsweise Seitenwände, welche den Raum der Aufnahme, in welcher Teile des Lagerelementes zu liegen kommen, mindestens teilweise begrenzen. Die Begrenzungsbereiche stehen vorzugsweise in direktem Kontakt mit dem Lagerteil.In other words, the delimitation areas are, in particular, arranged in such a way that they prevent movement of the bearing element in the receptacle transversely to the direction of insertion. The delimitation areas are, for example, side walls which at least partially delimit the space of the receptacle in which parts of the bearing element come to lie. The boundary areas are preferably in direct contact with the bearing part.

Die Steckrichtung zur Herstellung der besagten Verbindung ist rechtwinklig zur rückwärtigen Oberfläche der Lagerplatte orientiert.The direction of insertion for establishing said connection is oriented at right angles to the rear surface of the bearing plate.

Das Anschlagselement ist vorzugsweise um eine Achse federnd verschwenkbar. Die Orientierung dieser Achse kann rechtwinklig oder parallel zum Basisabschnitt sein.The snap body preferably has a flat base section, said stop element extending at right angles from the base section. The stop element can preferably be pivoted resiliently about an axis. The orientation of this axis can be perpendicular or parallel to the base section.

Die Orientierung kann aber auch in Abhängigkeit zur Steckrichtung definiert werden. Vorzugsweise steht die Achse rechtwinklig zur Steckrichtung.The orientation can also be defined depending on the direction of insertion. The axis is preferably perpendicular to the direction of insertion.

Der Basisabschnitt liegt vorzugsweise an einer ebenen Fläche der Aufnahme flächig an.The base section preferably lies flat against a flat surface of the receptacle.

Vorzugsweise wird das Lagerelement unter Vorspannung montiert, derart, dass das mindestens eine Betätigungselement in seiner Ausgangslage gehalten wird.

Durch die Vorspannung bzw. der daraus resultierenden Kraft, wird das Betätigungselement nach Betätigung wieder in seine Ausgangslage bewegt.The bearing element is preferably mounted under pretension in such a way that the at least one actuating element is held in its initial position. After actuation of the actuating element, it is actuated against a force provided by the preload. Due to the preload or the resulting force, the actuating element is moved back into its initial position after actuation.

Vorzugsweise wird die Vorspannung durch eine winklig geneigte Ausbildung der Aufnahme zur Lagerplatte und/oder zum Betätigungselement erreicht, wobei die Neigung vorzugsweise derart ist, dass der Abstand zwischen Aufnahme und Lagerplatte bzw. Betätigungselement mit abnehmender Distanz zur Mitte des Lagerelementes kleiner wird. Beispielsweise kann hierfür die oben erwähnte ebene Fläche der Aufnahme winklig geneigt ausgebildet sein.The prestress is preferably achieved by an angularly inclined design of the receptacle relative to the bearing plate and / or the actuating element, the inclination preferably being such that the distance between the receptacle and the bearing plate or actuating element becomes smaller as the distance to the center of the bearing element decreases. For example, the above-mentioned flat surface of the receptacle can be designed to be inclined at an angle.

Alternativ kann die Vorspannung auch durch das Lagerelement selbst erreicht werden. Hierfür weist das Lagerelement zwischen den beiden Enden, insbesondere mittig zwischen den beiden Enden, eine Knickstelle zur Vorspannung des Lagerelementes als solches.Alternatively, the prestress can also be achieved by the bearing element itself. For this purpose, the bearing element has a kink between the two ends, in particular centrally between the two ends, for pretensioning the bearing element as such.

Besonders bevorzugt wird die Vorspannung durch die oben erwähnte geneigte Fläche und durch den oben erwähnten Knick erreicht.The prestress is particularly preferably achieved by the above-mentioned inclined surface and by the above-mentioned kink.

Erfindungsgemäss ist das gefedert ausgebildete Lagerelement ein aus einem federelastischen Werkstoff. Besonders bevorzugt ist das Lagerelement ein aus Federstahl gefertigtes Stanz- und Biegeteil. Das Lagerelement kann aber auch aus Kunststoff sein.According to the spring-formed bearing element is made of a resilient material. The bearing element is particularly preferably a stamped and bent part made of spring steel. The bearing element can also be made of plastic.

Die Lagerplatte und das mindestens eine Betätigungselement sind vorzugsweise aus Kunststoff und werden mittels eines Kunststoffspritgiessverfahrens hergestellt.The bearing plate and the at least one actuating element are preferably made of plastic and are produced by means of a plastic injection molding process.

Das Betätigungselement ist vorzugsweise eine Betätigungstaste. Besonders bevorzugt sind pro Lagerplatte jeweils zwei Betätigungselemente, insbesondere zwei Betätigungstasten angeordnet.The actuating element is preferably an actuating button. Two actuating elements, in particular two actuating buttons, are particularly preferably arranged per bearing plate.

Vorzugsweise ist das mindestens eine Betätigungselement mit zwei im Abstand zueinander angeordneten Lagerelementen an der Lagerplatte gelagert. Hierdurch ergeht eine besonders stabile Lagerung.The at least one actuating element is preferably mounted on the bearing plate with two bearing elements arranged at a distance from one another. This results in a particularly stable storage.

In einer weiteren Ausführungsform wird das Ende des Lagerelementes, welches nicht über die besagte Steckverbindung mit der Lagerplatte und/oder dem Betätigungselement in Verbindung steht an der Lagerplatte bzw. dem Betätigungselement während des Spritzgiessverfahrens angespritzt. Das heisst, dass das Lagerelement in die Spritzgiessform eingelegt wird und dann mit seinem Ende an die Lagerplatte bzw. an das Betätigungselement angespritzt wird. Das Lagerelement ist in dieser Ausführungsform als Einlegeteil ausgebildet. In dieser Ausführungsform ist mit anderen Worten ein Ende des Lagerelementes mit der Steckverbindung mit der Lagerplatte oder dem Betätigungselement in Verbindung und mit dem anderen Ende steht das Lagerelement mit dem Betätigungselement oder der Lagerplatte in Verbindung.In a further embodiment, the end of the bearing element, which is not connected to the bearing plate and / or the actuating element via the said plug connection, is injection-molded onto the bearing plate or the actuating element during the injection molding process. This means that the bearing element is inserted into the injection mold and then its end is molded onto the bearing plate or onto the actuating element. In this embodiment, the bearing element is designed as an insert. In other words, in this embodiment, one end of the bearing element is connected to the plug connection with the bearing plate or the actuating element and the other end is connected to the actuating element or the bearing plate.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

Die Figur 1 zeigt eine Betätigungseinheit 1 für die Betätigung einer Spüleinrichtung. Die Spüleinrichtung kann beispielweise ein in einem Spülkasten angeordnetes Spülventil sein.The Figure 1 shows an actuating unit 1 for actuating a flushing device. The flushing device can be, for example, a flushing valve arranged in a flushing cistern.

Die Betätigungseinheit 1 umfasst eine Lagerplatte 2 und mindestens ein, hier zwei, relativ zur Lagerplatte 2 bewegbare Betätigungselemente 3. Die Betätigungselemente 3 lassen sich zur feststehenden Lagerplatte 2 bewegen, insbesondere verschwenken. Das mindestens eine Betätigungselement 3 wirkt dabei auf die Spüleinrichtung, welche in den Figuren nicht dargestellt ist, in bekannter Art und Weise ein.The actuating unit 1 comprises a bearing plate 2 and at least one, here two, actuating elements 3 that can be moved relative to the bearing plate 2. The actuating elements 3 can be moved to the fixed bearing plate 2, in particular pivoted. The at least one actuating element 3 acts on the flushing device, which is not shown in the figures, in a known manner.

Die Lagerplatte 2 weist eine Vorderseite 15, welche in der Figur 1 gezeigt ist, und eine Rückseite 16 mit einer rückwärtigen Oberfläche 13 auf. Über die Rückseite 16 bzw. die rückwärtigen Oberfläche 13 wird die Betätigungseinheit 1 beispielsweise an einem Rahmen oder einem Spülkasten befestigt.The bearing plate 2 has a front 15, which in the Figure 1 and a rear side 16 with a rear surface 13. The actuating unit 1 is fastened, for example, to a frame or a cistern via the rear side 16 or the rear surface 13.

Die Lagerplatte 2 sowie das Betätigungselement 3 werden vorzugsweise aus Kunststoff hergestellt. Insbesondere mit einem Spritzgiessverfahren.The bearing plate 2 and the actuating element 3 are preferably made of plastic. Especially with an injection molding process.

In den Figuren 2 bis 6 werden verschiedene Ausführungsformen von der Rückseite 16 der Betätigungseinheit 1 her gezeigt. Die Betätigungseinheit 1 umfasst nebst der Lagerplatte 2 und dem mindestens einen relativ zur Lagerplatte 2 bewegbaren Betätigungselement 3 mindestens ein gefedert ausgebildetes Lagerelement 4. Das Lagerelement 4 steht mit einem ersten Ende 5 mit der Lagerplatte 2 und mit einem zweiten Ende 6 mit dem mindestens einem Betätigungselement 3 in Verbindung. Das Betätigungselement 3 steht also über das Lagerelement 4 mit der Lagerplatte 2 in Verbindung. Mit anderen Worten gesagt lenkt das Lagerelement 4 das Betätigungselement 3 an der Platte an und bildet eine Art Scharnier, welches die Bewegung zwischen Betätigungselement 3 und feststehender Platte ermöglicht. Die Betätigungselemente 3 sind demnach gelenkig mit dem gefedert ausgebildeten Lagerelementen 4 verbunden. Beim Druck auf das Betätigungselement 3 wird dieses relativ zur Platte zur Rückseite 16 verschwenkt. Sobald der Druck wegfällt sorgt die Lagerplatte 2 aufgrund ihrer gefederten Ausbildung für eine Rückstellung des Betätigungselementes 3 in die Ausgangslage.In the Figures 2 to 6 Various embodiments are shown from the rear 16 of the actuating unit 1. In addition to the bearing plate 2 and the at least one actuating element 3 which is movable relative to the bearing plate 2, the actuating unit 1 comprises at least one spring-loaded bearing element 4. The bearing element 4 has a first end 5 with the bearing plate 2 and a second end 6 with the at least one actuating element 3 in connection. The actuating element 3 is thus connected to the bearing plate 2 via the bearing element 4. In other words, the bearing element 4 articulates the actuating element 3 on the plate and forms a kind of hinge which enables the movement between the actuating element 3 and the fixed plate. The actuating elements 3 are accordingly articulated to the spring-formed bearing elements 4. When the actuating element 3 is pressed, it is pivoted relative to the plate toward the rear 16. As soon as the pressure drops, the bearing plate 2 ensures a resetting of the actuating element 3 into the starting position due to its spring-loaded design.

In der gezeigten, nicht unter die Erfindung fallenden Form der Betätigungseinheit sind zwei Betätigungselemente 3 nebeneinander angeordnet. Jedes der Betätigungselemente 3 ist mit jeweils zwei Lagerelementen 4 mit der Lagerplatte 2 in Verbindung. Die Zahl der Betätigungselemente 3 kann auch kleiner oder grösser sein. Ebenso kann die Zahl der Lagerelemente pro Betätigungselement 3 ebenfalls kleiner oder grösser sein.In the form of the actuation unit which is not covered by the invention, two actuation elements 3 are arranged next to one another. Each of the actuating elements 3 is connected to the bearing plate 2 by two bearing elements 4. The number of actuating elements 3 can also be smaller or larger. Likewise, the number of bearing elements per actuating element 3 can also be smaller or larger.

Das Lagerelement 4 ist mit mindestens einem der beiden Enden 5, 6 über eine formschlüssige und/oder kraftschlüssige Verbindung mit der Lagerplatte 2 und/oder dem Betätigungselement 3 in Verbindung. Die Verbindung zwischen Lagerelement 4 und Lagerplatte 2 bzw. Betätigungselement 3 ist demnach nicht stoffschlüssig. Das heisst bei der Herstellung der Verbindung kommt es zu keinerlei Aktionen, welche einen Stoffschluss bedingen.The bearing element 4 is connected to at least one of the two ends 5, 6 via a positive and / or non-positive connection with the bearing plate 2 and / or the actuating element 3. The connection between the bearing element 4 and the bearing plate 2 or actuating element 3 is therefore not cohesive. This means that there are no actions during the establishment of the connection that require a material connection.

Besonders bevorzugt steht das Lagerelement 4 mit beiden Enden 5, 6 über die formschlüssige und/oder kraftschlüssige Verbindung mit der Lagerplatte 2 und dem Betätigungselement 3 in Verbindung. Das heisst die Verbindung von Lagerelement 2 zur Lagerplatte 2 und die Verbindung von Lagerplatte 2 zum Betätigungselement 3 ist vorzugsweise gleich ausgebildet.The bearing element 4 is particularly preferably at both ends 5, 6 via the positive and / or non-positive connection with the bearing plate 2 and the Actuator 3 in connection. That is, the connection of the bearing element 2 to the bearing plate 2 and the connection of the bearing plate 2 to the actuating element 3 is preferably of the same design.

Dabei ist die besagte Verbindung als mechanische Schnappverbindung ausgebildet. Die Schnappverbindung umfasst dabei eine Aufnahme 7 und einen Schnappkörper 8. Der Schnappkörper 8 ist dabei in die Aufnahme 7 einschiebbar und wird dort formschlüssig und/oder kraftschlüssig, nicht aber stoffschlüssig, gehalten.The said connection is designed as a mechanical snap connection. The snap connection comprises a receptacle 7 and a snap body 8. The snap body 8 can be inserted into the receptacle 7 and is held there in a form-fitting and / or force-fitting manner, but not materially.

Die Aufnahme 7 ist jeweils am Betätigungselement 3 und der Lagerplatte 2 angeordnet und der Schnappkörper 8 ist Teil des Lagerelementes 4. Dabei stellen die Enden 5, 6 des Lagerelementes 4 die Schnappkörper 8 bereit.The receptacle 7 is arranged on the actuating element 3 and the bearing plate 2 and the snap body 8 is part of the bearing element 4. The ends 5, 6 of the bearing element 4 provide the snap body 8.

Die Ausbildung der Aufnahme 7 und auch die Ausbildung der Schnappkörper ist in der Form nach den Figuren 2 bis 4 unterschiedlich zu der erfindungsgemässen Ausführungsform nach den Figuren 5 und 6.The formation of the receptacle 7 and the formation of the snap body is in the form of the Figures 2 to 4 different from the embodiment according to the invention according to the Figures 5 and 6 .

In der Ausbildung nach den Figuren 2 bis 4 werden die Schnappkörper 8 entlang einer Steckrichtung S, welche hier parallel zur rückwärtigen Oberfläche 13 verläuft, in die Aufnahme 7 eingeschoben. Das heisst, der Schnappkörper 8 wird entlang der Steckrichtung S parallel zur rückwärtigen Oberfläche 13 während der Montage bewegt und so in die Aufnahme 7 eingesetzt.In training after the Figures 2 to 4 the snap bodies 8 are inserted into the receptacle 7 along a plug-in direction S, which here runs parallel to the rear surface 13. This means that the snap body 8 is moved along the insertion direction S parallel to the rear surface 13 during assembly and is thus inserted into the receptacle 7.

In der erfindungsgemässen Ausführungsform nach den Figuren 5 bis 6 werden die Schnappkörper 8 entlang einer Steckrichtung S, welche hier rechtwinklig zur rückwärtigen Oberfläche 13 verläuft, in die Aufnahme 7 eingeschoben. Das heisst, die Montage kann somit von oben erfolgen, was unter gewissen Umständen einen Vorteil darstellen kann.In the embodiment according to the invention Figures 5 to 6 the snap bodies 8 are inserted into the receptacle 7 along a plug-in direction S, which runs here at right angles to the rear surface 13. This means that the assembly can be done from above, which can be an advantage in certain circumstances.

Die Wahl, ob die Form der Betätigungseinheit mit der Montagerichtung parallel zur rückwärtigen Oberfläche 13 oder die erfindungsgemässe Ausführungsform mit der Montagerichtung rechtwinklig zur rückwärtigen Oberfläche 13 eingesetzt wird, hängt im Wesentlichen von den geometrischen Gegebenheiten, welche sich aufgrund der Form der Lagerplatte 2 und der Betätigungselemente 3 ergibt, ab.The choice of whether the shape of the actuator unit is parallel to the mounting direction rear surface 13 or the embodiment according to the invention is used with the mounting direction perpendicular to the rear surface 13 depends essentially on the geometric conditions, which are due to the shape of the bearing plate 2 and the actuators 3 results from.

Vorzugsweise verfügt das Lagerelement 4 im Bereich des Schnappkörpers 8 über mindestens ein gefedert ausgebildetes Anschlagselement 9. Hier sind zwei seitlich zum Lagerelement 4 angeordnete Federlaschen 10 als Anschlagselement 9 vorgesehen. Die Federlasche 10 federt bei der Montage leicht ein und ragt dann in die Ausnehmung 11 ein. Die Aufnahme 7 hat weiterhin eine Ausnehmung 11 mit einer Flanke 12. Das Anschlagselement 9 kommt dabei mit der Ausnehmung 11 und der Flanke 12 in Kontakt. Dabei ragt das Anschlagselement 9 in die Ausnehmung 11 ein und steht mit einer Fläche an der Flanke 12 an. Durch diesen Kontakt kann eine Bewegung gegen die Steckrichtung S verhindert werden, sobald die Schnappverbindung zwischen der Aufnahme 7 und dem Schnappkörper 8 hergestellt ist. Dies wird insbesondere in den Figuren 3 und 6 verdeutlicht: Wenn nun eine Kraft F entgegen der Steckrichtung S aufgebracht wird, so wirken das Anschlagselement 9, welches mit der Flanke 12 in Kontakt ist, entgegen dieser Bewegung und blockieren den Schnappkörper 8 entsprechend in der Aufnahme 7.The bearing element 4 preferably has at least one spring-loaded stop element 9 in the region of the snap body 8. Two spring tabs 10 arranged laterally to the bearing element 4 are provided as stop element 9. The spring tab 10 springs slightly during assembly and then protrudes into the recess 11. The receptacle 7 also has a recess 11 with a flank 12. The stop element 9 comes into contact with the recess 11 and the flank 12. The stop element 9 projects into the recess 11 and is in contact with a surface on the flank 12. A movement against the plug direction S can be prevented by this contact as soon as the snap connection between the receptacle 7 and the snap body 8 is established. This is particularly evident in the Figures 3 and 6 illustrates: If a force F is now applied counter to the insertion direction S, the stop element 9, which is in contact with the flank 12, counteracts this movement and accordingly blocks the snap body 8 in the receptacle 7.

Andere Ausbildungen des Anschlagelementes 9 sind ebenfalls denkbar.Other designs of the stop element 9 are also conceivable.

Die Flanke 12 ist vorzugsweise leicht winklig zur Steckrichtung S geneigt ausgebildet. Die Neigung ist dabei so, dass bei der Anwendung der Kraft F die Federlasche 10 blockiert wird oder dass die Federlasche 10 sich weiter vom Schnappkörper 8 weg entfernt und so der Bewegung in Steckrichtung S entgegenwirkt.The flank 12 is preferably inclined at a slight angle to the insertion direction S. The inclination is such that when the force F is applied, the spring tab 10 is blocked or that the spring tab 10 moves further away from the snap body 8 and thus counteracts the movement in the insertion direction S.

Die Aufnahme 7 umfasst weiter Begrenzungsbereiche 19, welche derart ausgebildet sind, dass diese die Bewegung des Lagerteils 4 in alle Richtungen ausser in die Richtung gegen die Steckrichtung S einschränkt. Die Begrenzungsbereiche 19 werden in der gezeigten Ausführungsform durch Wandbereiche der Aufnahme bereitgestellt. Bezüglich der Bewegung gegen die Steckrichtung S wirkt das Anschlagselement. Folglich wird das Lagerteil 4 in der Aufnahme 7 festgesetzt und kann nicht relativ zur Aufnahme 7 verschoben werden.The receptacle 7 further includes boundary areas 19 which are designed such that they restrict the movement of the bearing part 4 in all directions except in the direction opposite to the plug-in direction S. In the embodiment shown, the delimitation areas 19 are provided by wall areas of the receptacle. The stop element acts with respect to the movement against the insertion direction S. Consequently, the bearing part 4 is fixed in the receptacle 7 and cannot be moved relative to the receptacle 7.

In den gezeigten Ausführungsformen nach den Figuren 2 bis 6 ist das Anschlagselement 9 Teil des Schnappkörpers 8 und die Ausnehmung 11 mit der Flanke 12 sind Teile der Aufnahme 7. Eine umgekehrte Anordnung ist aber auch denkbar.In the embodiments shown after the Figures 2 to 6 is the stop element 9 part of the snap body 8 and the recess 11 with the flank 12 are parts of the receptacle 7. An inverted arrangement is also conceivable.

Der Schnappkörper 8 weist einen ebenen Basisabschnitt 18 auf. Das besagte Anschlagselement 9 erstreckt sich dabei vom Basisabschnitt 18 rechtwinklig weg. In der Form nach den Figuren 2 bis 4 kann das Anschlagselement 9 um eine Achse, welche rechtwinklig zum Basisabschnitt 18 orientiert ist, federnd sich relativ zum Basisabschnitt 18 verschwenken. In der erfindungsgemässen Ausführungsform nach den Figuren 5 bis 6 kann das Anschlagselement 9 um eine Achse, welche parallel zum Basisabschnitt 18 orientiert ist, federnd sich relativ zum Basisabschnitt 14 verschwenken.The snap body 8 has a flat base section 18. Said stop element 9 extends away from base section 18 at right angles. In the form of the Figures 2 to 4 the stop element 9 can pivot about an axis which is oriented at right angles to the base section 18, relative to the base section 18. In the embodiment according to the invention Figures 5 to 6 the stop element 9 can pivot about an axis which is oriented parallel to the base section 18, relative to the base section 14.

Der Basisabschnitt 18 liegt dabei flächig in der Aufnahme 7 auf.The base section 18 lies flat in the receptacle 7.

Weiter erstrecken sich Haltebereiche 17 ebenfalls rechtwinklig vom Basisabschnitt 18 weg. Diese Haltebereiche 17 stehen dabei mit Teilen der Aufnahme 7, hier mit entsprechenden Begrenzungsbereiche 19 in Kontakt, so dass der Schnappkörper 8 nicht aus der Aufnahme 7 herausfallen kann.Furthermore, holding areas 17 also extend at right angles from the base section 18. These holding areas 17 are in contact with parts of the receptacle 7, here with corresponding delimitation areas 19, so that the snap body 8 cannot fall out of the receptacle 7.

In der Figur 5 wird aber auch noch eine weitere Variante gezeigt. Beim Betätigungselement 3, welches rechter Hand angeordnet ist, ist die Verbindung zwischen Lagerplatte 2 und Lagerelement 4 gemäss der erfindungsgemässen Ausführungsform ausgebildet und die Verbindung zwischen Lagerelement 4 und Betätigungselement 3 ist nach der nicht unter die Erfindung fallenden Form ausgebildet. Das heisst, die in Figur 2 bis 4 gezeigte Verbindungsform mit der erfindungsgemässen Ausführungsform der Verbindung kann an jeweils einem Ende eines Lagerelements verwendet werden.In the Figure 5 another variant is also shown. In the actuating element 3, which is arranged on the right hand, the connection between the bearing plate 2 and the bearing element 4 is formed according to the embodiment according to the invention and the connection between the bearing element 4 and the actuating element 3 is designed in accordance with the form not covered by the invention. That is, the in Figure 2 to 4 Connection form shown with the embodiment of the connection according to the invention can be used at one end of a bearing element.

Das Lagerelement 4 ist, vorzugsweise in allen Ausführungsformen, unter Vorspannung montiert, und zwar derart, dass das mindestens eine Betätigungselement 3 in seiner Ausgangslage gehalten wird. Das Betätigungselement 3 weist dabei einen Ansatz 20 auf, welcher an einem korrespondierenden Bereich 21 der rückwärtigen Oberfläche 13 entsprechend ansteht. Das heisst, die Vorspannung drückt das Betätigungselement 3 mit dem Ansatz 20 immer an den korrespondierenden Bereich 21, welcher einen Anschlag bezüglich einer Bewegung des Lagerelementes nach vorne bildet.The bearing element 4 is, preferably in all embodiments, mounted under pretension in such a way that the at least one actuating element 3 is held in its initial position. The actuating element 3 has an extension 20, which on a corresponding region 21 of the rear surface 13 pending accordingly. This means that the pretension always presses the actuating element 3 with the projection 20 against the corresponding region 21, which has a stop forms a forward movement of the bearing element.

Die Vorspannung kann verschiedenartig erreicht werden. Besonders bevorzugt ist es, dass die Vorspannung durch eine winklig geneigte Ausbildung der Aufnahme 7 zur Lagerplatte 2 und/oder zum Betätigungselement 3 erreicht wird. Die Neigung kann beispielsweise in der Figur 3 erkannt werden. Der Basisabschnitt 18 liegt hier leicht schräg bzw. winklig geneigt zur rückwärtigen Oberfläche 13. Die Neigung der Aufnahme 7 ist vorzugsweise derart, dass der Abstand zwischen Aufnahme 7 und Lagerplatte 2 bzw. Betätigungselement 3 mit abnehmender Distanz zur Mitte des Lagerelementes 4 kleiner wird. Hierdurch wird die entsprechende Vorspannung erreicht.The preload can be achieved in various ways. It is particularly preferred that the pretensioning is achieved by an angularly inclined configuration of the receptacle 7 relative to the bearing plate 2 and / or the actuating element 3. The inclination can, for example, in the Figure 3 be recognized. The base section 18 here lies slightly obliquely or at an angle to the rear surface 13. The inclination of the receptacle 7 is preferably such that the distance between the receptacle 7 and the bearing plate 2 or actuating element 3 becomes smaller as the distance to the center of the bearing element 4 decreases. The corresponding preload is hereby achieved.

Die Vorspannung kann aber auch durch eine Knickstelle 14, welche der Vorspannung des Lagerelementes 4 als solches dient, erreicht werden. Auch ist es denkbar, dass man die beiden Konzepte, nämlich die winklig geneigte Ausbildung der Aufnahme 7 und Knickstelle 14 miteinander kombiniert.The bias can also be achieved by a kink 14, which serves to bias the bearing element 4 as such. It is also conceivable that the two concepts, namely the angularly inclined design of the receptacle 7 and kink 14, are combined with one another.

Im Bereich der Knickstelle kann das Lagerelement 4 seitlich leicht eingeschnürt sein.In the area of the kink, the bearing element 4 can be slightly constricted on the side.

Das Lagerelement 4 ist in allen Ausführungsformen aus einem federelastischem Werkstoff, insbesondere Federstahl, hergestellt. Grundsätzlich sind aber auch andere federelastische Werkstoffe denkbar.The bearing element 4 is made in all embodiments from a resilient material, in particular spring steel. In principle, however, other spring-elastic materials are also conceivable.

In der Figur 7 wird eine Detailansicht des Lagerelementes 4 und Teilen von Lagerplatte 2 und Betätigungselement 3 nach einer weiteren, nicht unter die Erfindung fallenden Form gezeigt. In dieser Form wird das Ende 6 des Lagerelementes 4 dem Betätigungselement 3 während des Spritzgiessverfahrens angespritzt. Das wird durch den angespritzten Bereich 22 gezeigt. Das hiesst das Lagerelement 4 wird integraler Bestandteil des Betätigungselementes 3. Das erste Ende 5 steht über eine der oben beschriebenen formschlüssigen und/oder kraftschlüssigen Verbindung mit der Lagerplatte 2 in Verbindung. Allgemein ausgedrückt heisst dies, dass das Ende 6 des Lagerelementes, welches nicht über die besagte Steckverbindung dem Betätigungselement in Verbindung steht, dem Betätigungselement während des Spritzgiessverfahrens angespritzt wird.In the Figure 7 a detailed view of the bearing element 4 and parts of the bearing plate 2 and the actuating element 3 is shown according to a further form not falling under the invention. In this form, the end 6 of the bearing element 4 is molded onto the actuating element 3 during the injection molding process. This is shown by the molded area 22. This means that the bearing element 4 becomes an integral part of the actuating element 3. The first end 5 is connected to the bearing plate 2 via one of the positive and / or non-positive connection described above. In general terms, this means that the end 6 of the bearing element, which is not connected to the actuating element via the said plug connection, is molded onto the actuating element during the injection molding process.

Die Konfiguration nach Figur 7 kann auch umgekehrt sein: Die angespritzte Verbindung kann auch zwischen dem ersten Ende 5 und der Lagerplatte 2 vorgesehen sein, während dann das zweite Ende 6 mit dem Betätigungselement 3 über eine der oben beschriebenen formschlüssigen und/oder kraftschlüssigen Verbindung in Verbindung steht.
