Description

Die Erfindung bezieht sich auf eine Schaltervorrichtung, insbesondere für ein Haushaltsgerät, der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a switch device, in particular for a household appliance, the type explained in the preamble of claim 1.

Schaltervorrichtungen, insbesondere für Haushaltsgeräte, müssen verschiedene Bedingungen erfüllen. Sie müssen für den Benutzer leicht zugänglich und gut zu betätigen sein, sie müssen robust und dauerhaft ausgebildet und befestigt sein, sie müssen ästhetischen Gesichtspunkten genügen und sie müssen sich zeitsparend und unkompliziert montieren lassen. Des weiteren sollte es möglich sein, auch standardisierte, sogenannte Katalog-Teile einzusetzen, wann immer dies möglich ist.Switching devices, especially for household appliances, have to fulfill different conditions. They must be easy for the user to access and operate well, they must be robust and durable trained and fixed, they must meet aesthetic aspects and they must be time-saving and easy to assemble. Furthermore, it should be possible to use standardized, so-called catalog parts whenever possible.

Aus US 4,242,545 ist eine mechanische Schalter vorrichtung nach dem Oberbegriff des Anspruchs 1 mit einer Drucktastenfunktion bekannt. Herkömmliche Schaltervorrichtungen weisen in dieser Hinsicht einige Defizite auf. So ist es beispielsweise immer noch notwendig, die Schalt- oder Reglerelemente, d.h. den elektrischen Teil der Schaltvorrichtung, mit einer Trägerstruktur zu verschrauben. Dies geschieht gegenwärtig beispielsweise bei versenkbaren Herdknöpfen dadurch dass man zunächst das Schalt- oder Reglerelement mit einer Trägerstruktur verschraubt, wobei sich eine Betätigungswelle des Schalt- oder Reglerelementes durch eine Öffnung in der Trägerstruktur erstreckt, und man anschließend einen Handgriff mit einer Betätigungs-Hohlwelle von der gegenüberliegenden Seite der Trägerstruktur auf die Betätigungswelle des Schalt- oder Reglerelementes aufschiebt. Bei dieser Konstruktion wird somit der Betätigungsknopf oder Handgriff durch das angeschraubte Schalt- oder Reglerelement gehalten. Dies ist sowohl im Hinblick auf den Zeitaufwand als auch im Hinblick auf die Reihenfolge der Montage nachteilig.Out US 4,242,545 is a mechanical switch device according to the preamble of claim 1 with a push-button function known. Conventional switch devices have some deficiencies in this regard. For example, it is still necessary to bolt the switching or control elements, ie the electrical part of the switching device, to a carrier structure. This happens currently, for example, retractable stove buttons in that first screwed the switching or control element with a support structure, wherein an actuating shaft of the switching or control element extends through an opening in the support structure, and then a handle with an actuating hollow shaft of the opposite side of the support structure aufschiebt on the actuating shaft of the switching or control element. In this construction, the operating knob or handle is thus held by the screwed on switching or control element. This is disadvantageous both in terms of time and in terms of the order of assembly.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Schaltervorrichtung zu schaffen, die einfacher und schneller montierbar ist.The invention is therefore an object of the invention to provide a switch device that is easier and faster to install.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße Ausgestaltung wird eine Schaltervorrichtung geschaffen, die einfach und unkompliziert sowie ohne aufwendige Verschraubungen befestigt werden kann.Due to the inventive design, a switch device is provided which can be attached easily and easily and without expensive screwing.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

So bietet insbesondere die Verwendung eines Befestigungsteils den Vorteil, dass die Montage aufeinanderfolgend in einer einzigen Richtung vorgenommen werden kann.In particular, the use of a fastening part offers the advantage that the assembly can be made sequentially in a single direction.

Zu diesem Zweck sitzt der Handgriff 7 auf einer Betätigungswelle 9, die verdrehbar, teleskopisch zusammendrückbar und im zusammengedrückten Zustand verriegelbar ist, wie dies bei derartigen Betätigungselementen üblich ist, so dass auf eine nähere Beschreibung verzichtet werden kann. Die Betätigungswelle 9 sitzt axial unverschiebbar, aber verdrehbar in einer Halterung 10 im Boden 8a des Befestigungsteils 8 und befestigt auf diese Weise den Handgriff 7 am Befestigungsteil 8.The actuator 2 is in the illustrated embodiment, a knob for a household appliance, in particular an electric cooker. The actuator 2 includes a handle 7, which is formed in the usual way as a knob. The handle 7 is, as well Fig. 3 shows, in a cup-shaped or pot-shaped fastening part 8 twisted and absorbed added. For this purpose, the handle 7 sits on an actuating shaft 9, the rotatable, telescopically compressible and compressed Locked state is, as is usual in such actuators, so that can be dispensed with a more detailed description. The actuating shaft 9 is seated axially immovable, but rotatable in a holder 10 in the bottom 8 a of the fastening part 8 and secured in this way the handle 7 on the fastening part eighth

Das Befestigungsteil 8 weist an seinem, dem Handgriff 7 zugewandten, oberen Rand eine Befestigungseinrichtung 11 auf, mit der das Befestigungsteil 8 an einer nicht gezeichneten Trägerstruktur, beispielsweise direkt an einer Abdeckblende der Front eines Haushaltsgerätes oder einer ähnlichen Trägerstruktur zu befestigen ist. Die Befestigungseinrichtung 11 ist im dargestellten Ausführungsbeispiel durch vom Befestigungsteil 8 vorstehende und abwechselnd in Axialrichtung.versetzt angeordnete Stege gebildet, die eine Art Bajonettverschluss darstellen, mit dem das gesamte Betätigungselement 2 am Haushaltsgerät befestigt werden kann.The fastening part 8 has at its, the handle 7 facing the upper edge of a fastening device 11 with which the fastening part 8 is to be attached to a support structure, not shown, for example, directly to a cover of the front of a household appliance or similar support structure. The fastening device 11 is formed in the illustrated embodiment by protruding from the fastening part 8 and alternately arranged in the axial direction. Webs arranged, which constitute a kind of bayonet lock, with which the entire actuator 2 can be attached to the household appliance.

Im Boden 8a des Befestigungsteiles 8 ist ein Rastelement in Form von Aufnahmeöffnungen 12 für eine Rastverbindung 13 vorgesehen. Im dargestellten Ausführungsbeispiel sind zwei einander diametral gegenüberliegende Aufnahmeöffnungen 12 angeordnet, die schlitzförmig ausgebildet sind und in eine sich axial zum Befestigungselement 8 erstreckende Führung 14 münden, die nutförmig ausgebildet ist und entweder an der Außenseite oder an der Innenseite einer Umfangswandung 8b des napf- bzw. topfförmigen Befestigungsteils 8 ausgebildet sind.In the bottom 8a of the fastening part 8, a latching element in the form of receiving openings 12 for a latching connection 13 is provided. In the illustrated embodiment, two diametrically opposed receiving openings 12 are arranged, which are slit-shaped and open into an axially extending to the fastener 8 guide 14, which is groove-shaped and either on the outside or on the inside of a peripheral wall 8b of the cup or cup-shaped fastening part 8 are formed.

Die Aufnahmeöffnungen 12 und die Führungen 14 sind so ausgestaltet, dass sie in der Lage sind, jeweils ein Rastelement in Form eines Hakens 15 der Rastverbindung 13 aufzunehmen.The receiving openings 12 and the guides 14 are configured so that they are able to receive in each case a latching element in the form of a hook 15 of the latching connection 13.

Die Haken 15 sind im Ausführungsbeispiel gemäß Fig. 1 an einem Schalterträger 16 angeordnet, bevorzugt angeformt. Der Schalterträger 16 enthält eine Basis 17, die im dargestellten Ausführungsbeispiel plattenförmig ausgebildet ist, und eine Mittelöffnung 17a für die Betätigungswelle 5 des Schalt- und Reglerelementes 3 sowie Schraublöcher 17b aufweist, die mit den Schraublöchern 6a fluchten. An der Basis 17 kann weiterhin ein Stift 18 oder dgl. angeordnet sein, der als Abstandshalter dient: Der Schalterträger 16 wird mit dem Schalt- oder Reglerelement 3 verschraubt, so dass Schalterträger 16 und Reglerelement 3 eine Einheit bilden, die am Befestigungsteil 8 des Betätigungselementes 2 durch Einschnappen der Haken 15 in die Öffnungen 12 befestigt werden kann. Die Führungen 14 sorgen dafür, dass die Betätigungswelle 5 des Schalt- oder Reglerelementes 3 mit der Betätigungswelle 9 des Betätigungselementes 2 axial fluchtend ausgerichtet wird und auch im Betrieb und unter dem Gewicht vom Schalt- oder Reglerelement 3 und dem Schalterträger 16 ausgerichtet bleibt.The hooks 15 are in the embodiment according to Fig. 1 arranged on a switch carrier 16, preferably integrally formed. The switch carrier 16 includes a base 17, which is plate-shaped in the illustrated embodiment, and has a central opening 17a for the actuating shaft 5 of the switching and control element 3 and screw holes 17b, which are aligned with the screw holes 6a. On the base 17 may further be a pin 18 or the like. Be arranged, which serves as a spacer: The switch carrier 16 is bolted to the switching or control element 3, so that the switch carrier 16 and regulator element 3 form a unit which can be attached to the fastening part 8 of the actuating element 2 by snapping the hooks 15 in the openings 12. The guides 14 ensure that the actuating shaft 5 of the switching or control element 3 is aligned axially aligned with the actuating shaft 9 of the actuating element 2 and remains aligned during operation and under the weight of the switching or control element 3 and the switch carrier 16.

Je nach konstruktiver Ausgestaltung kann dabei die Betätigungswelle 5 direkt in eine an der Stirnseite der Betätigungswelle 9 angeordnete Kupplung 9a eingreifen, oder es ist, wie in Fig. 1 dargestellt, ein Kupplungsstück 19 zwischengeschaltet, wobei das Kupplungsstück 19 an einer Stirnseite eine Aufnahme für die Betätigungswelle 5 und an der anderen Seite ein Kupplungsgegenstück 19a für die Kupplung 9a aufweist.Depending on the structural design, the actuating shaft 5 can engage directly in a coupling 9a arranged on the end face of the actuating shaft 9, or it is, as in FIG Fig. 1 shown, a coupling piece 19 interposed, wherein the coupling piece 19 has on one end side a receptacle for the actuating shaft 5 and on the other side a coupling counterpart 19a for the coupling 9a.

Bei der Montage der erfindungsgemäßen Schalteranordnung 1 wird der Schalterträger 16 und das Schalt- oder Reglerelement 3 zu einer Einheit verschraubt, sowie gegebenenfalls das Kupplungsstück 19 auf die Betätigungswelle 5 aufgesetzt. Dann wird das Betätigungsteil 2 als Einheit montiert, indem der Handgriff 7 mit der Betätigungswelle 9, der Halterung 10 und dem topfförmigen Befestigungsteil 8 verbunden werden. Dann wird das topfförmige Befestigungsteil 8 über die Befestigungseinrichtung 11 an Ort und Stelle am Haushaltsgerät, beispielsweise an der Schalterfront eines Elektroherdes, befestigt und anschließend das Schalt- oder Reglerelement 3 mit dem Schalterträger. 16 einfach aufgedrückt, so dass die Haken 15 in die Aufnahmeöffnungen 12 eingreifen.When mounting the switch assembly 1 according to the invention, the switch carrier 16 and the switching or control element 3 is screwed into a unit, and optionally the coupling piece 19 is placed on the actuating shaft 5. Then, the operating member 2 is assembled as a unit by connecting the handle 7 to the operating shaft 9, the bracket 10 and the cup-shaped fixing member 8. Then the cup-shaped fastening part 8 is fastened via the fastening device 11 in place on the household appliance, for example on the switch front of an electric range, and then the switching or control element 3 with the switch carrier. 16 simply pressed so that the hooks 15 engage in the receiving openings 12.

Die Verriegelungskraft für die Rastverbindung 13 wird bevorzugt durch eine flexible Ausgestaltung der Haken 15 erreicht, wobei bevorzugt die Haken 15 aus einem flexibel federnden Material, insbesondere aus Kunststoff bestehen. Dabei sind die Haken 15, wie dies bei derartigen Schnapphaken üblich ist, mit einer Rampenfläche 15a versehen, die bewirken, dass sich die Haken beim Eindrücken in die Aufnahmeöffnungen 12 nach innen biegen und anschließend zurückfedern. Die Verriegelungskraft für die Rastverbindung 13 kann jedoch auch auf jede andere, übliche Weise aufgebracht werden.The locking force for the locking connection 13 is preferably achieved by a flexible embodiment of the hook 15, wherein preferably the hooks 15 are made of a flexible resilient material, in particular made of plastic. In this case, the hooks 15, as is customary in the case of such snap hooks, are provided with a ramp surface 15a, which causes the hooks to bend inwards when being pressed into the receiving openings 12 and then spring back. However, the locking force for the latching connection 13 can also be applied in any other, customary manner.

Fig. 2 zeigt in schematischer Darstellung ein weiteres Schalt- oder Reglerelement 30, das sich vom ersten Ausführungsbeispiel dadurch unterscheidet, dass hier die Haken 15 der Rastverbindung 13 direkt in das Reglerelement 30 integriert sind. Die Haken 15 sind in gleicher Weise wie beim ersten Ausführungsbeispiel beschrieben ausgebildet, so dass auf ihre nochmalige Beschreibung verzichtet wird. Die Haken 15 sind hier gesondert hergestellt und am Schalt- und Reglerelement unverlierbar befestigt. Fig. 2 shows a schematic representation of another switching or control element 30, which differs from the first embodiment in that here the hook 15 of the locking connection 13 are integrated directly into the controller element 30. The hooks 15 are formed in the same manner as described in the first embodiment, so that is dispensed with their repeated description. The hooks 15 are made separately here and secured captive on the switching and control element.

Fig. 3 zeigt ein drittes Ausführungsbeispiel eines Schalt- oder Reglerelementes 300, in das ebenfalls die bereits beschriebenen Haken 15 integriert sind; nur sind sie hier an das Gehäuse des Schalt- und Reglerelementes angeformt. Fig. 3 shows a third embodiment of a switching or control element 300, in which also the already described hooks 15 are integrated; only they are here formed on the housing of the switching and control element.

Beide Schalt- und Reglerelemente 30 bzw. 300 können an dem bereits anhand Fig. 1 beschriebenen, und auch in Fig. 3 gezeigten Betätigungselement 2 montiert sein.Both switching and control elements 30 and 300 can be based on the already Fig. 1 described, and also in Fig. 3 be shown actuator 2 mounted.

In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können die in den Zeichnungen gezeigten Einzelheiten untereinander ausgetauscht werden. So kann beispielsweise auch bei den Schalt- oder Reglerelementen der Fig. 2 und 3 ein Kupplungsstück vorgesehen sein. Die Erfindung ist nicht auf die Verwendung bei den gezeigten Elektroherd-Drehknöpfen beschränkt, sondern ist für alle Schalteranordnungen einsetzbar, bei denen die oben beschriebenen Vorteile im Hinblick auf eine leichtere und schnellere Montage zu erzielen sind. Das Befestigungsteil muss nicht unbedingt die gezeigte Napfform aufweisen, sondern kann jede Trägerstruktur sein, die geeignet ist, einen Handgriff und eine Betätigungswelle zu halten. Die Rastverbindung muss nicht unbedingt über die gezeigten Haken erfolgen, sondern kann beispielsweise auch in Form von Stiftaufnahmen mit Raststiften und dazu passenden Aufnahmeöffnungen erfolgen. Andere bekannte Konstruktionen einer Rastverbindung sind ebenfalls einsetzbar. Weiterhin können die Rastelemente vertauscht werden, d.h. beispielsweise die Haken am Befestigungsteil und die Aufnahmeöffnungen am Schalter bzw. am Schalterträger angeordnet sein.In a modification of the described and illustrated embodiments, the details shown in the drawings can be interchanged. Thus, for example, in the switching or control elements of FIGS. 2 and 3 be provided a coupling piece. The invention is not limited to use in the illustrated electric cooker knobs, but is applicable to all switch assemblies in which the above-described advantages with regard to easier and faster assembly can be achieved. The attachment member may not necessarily have the cup shape shown, but may be any support structure capable of holding a handle and an actuating shaft. The latching connection does not necessarily have to be done via the hooks shown, but can for example also take the form of pin receptacles with locking pins and matching receiving openings. Other known constructions of a latching connection can also be used. Furthermore, the latching elements can be reversed, ie, for example, the hooks on the fastening part and the receiving openings can be arranged on the switch or on the switch carrier.
