Description

Die Erfindung betrifft einen Mehrfunktionsschalter für elektrische Geräte mit den im ersten Teil des Patentanspruchs 1 enthaltenen Merkmalen.The invention relates to a multi-function switch for electrical devices with the features contained in the first part of claim 1.

Mehrfunktionsschalter sind in der Technik ganz allgemein gebräuchlich. Bei Kraftwagen wird zum Beispiel vielfach der Schalter, mittels dessen durch Schwenken eines Schalthebels die Blinkleuchten wechselseitig betätigbar sind, derart ausgebildet, dass durch Kippen des Schalthebels quer zu seiner Schwenkrichtung die Lichthupe und eine akustische Hupe betätigbar sind.Multi-function switches are very common in technology. In motor vehicles, for example, the switch, by means of which the turn signal lights can be actuated alternately by pivoting a shift lever, is designed in such a way that the flasher and an acoustic horn can be actuated by tilting the shift lever transversely to its pivoting direction.

Aus der DE-A2238363 ist ein in ein elektrisches Kabel einfügbarer, sogenannter Schnurschalter bekannt, der ein rohrförmiges, Einführungsöffnungen für das Kabel enthaltendes Gehäuse zur Unterbringung elektrischer und/oder elektronischer Einrichtungen sowie ein Mehrfunktionsbetätigungsglied aufweist, das zur Beeinflussung dieser Einrichtungen wahlweise verschiebbar und verdrehbar ist. Dieses Mehrfunktionsbetätigungsglied ist als Ringkörper ausgebildet, der die Trennfuge des quergeteilten und aus zwei zusammenfügbaren Rohrkörpern bestehenden Schaltergehäuses überdeckt. Nachteilig ist bei diesem bekannten Schnurschalter die Anordnung eines mit dem ringförmigen Betätigungsglied zusammenwirkenden, auf einen einstufigen Mikroschalter einwirkenden Schaltschiebers, der im Gehäuse nur montierbar ist, wenn das Gehäuse eine quer zu seiner Längsrichtung verlaufende Trennfuge aufweist. Darüber hinaus ist ein Betätigungsglied in Gestalt eines geschlossenen Ringkörpers am Griff von Elektrogeräten nur bedingt verwendbar; denn beispielsweise würde er die verfügbare, von der Hand umschliessbare Grifflänge eines sogenannten pistolenförmigen Handhaartrockners so einschränken, dass das Gerät nicht mehr angenehm und sicher in der Hand läge und die einhändige Schalterbetätigung stark erschwert wäre.From DE-A2238363 a so-called cord switch, which can be inserted into an electrical cable, is known, which has a tubular housing containing insertion openings for the cable for accommodating electrical and / or electronic devices as well as a multi-function actuator which can be moved and rotated to influence these devices . This multi-function actuator is designed as an annular body that covers the parting line of the cross-divided switch housing consisting of two pipe bodies that can be joined together. The disadvantage of this known cord switch is the arrangement of a switching slide interacting with the annular actuating element and acting on a single-stage microswitch, which slide switch can only be mounted in the housing if the housing has a parting line running transversely to its longitudinal direction. In addition, an actuator in the form of a closed ring body on the handle of electrical devices can only be used to a limited extent; Because, for example, he would limit the available, hand-enclosable handle length of a so-called gun-shaped hand hair dryer so that the device would no longer be comfortable and safe to hold and the one-handed switch operation would be extremely difficult.

In der WO 80/01 736 ist ebenfalls ein Mehrfunktionsschalter beschrieben und dargestellt, der jedoch in erster Linie für längliche, stabförmige elektrische Geräte geeignet ist, da sein als Dreh-Schiebe-Schaltglied vorgesehener Schaltring im allgemeinen zusätzliche Baulänge in Verlängerung des Griffbereiches erfordert. Mit einer aus der DE-A2708981 bekannten Schalteinrichtung ist dagegen nur die Betätigung eines einzigen Schiebeschalters, also nur einer einfachen Schaltfunktion, möglich.A multi-function switch is also described and shown in WO 80/01 736, but is primarily suitable for elongated, rod-shaped electrical devices, since its switching ring provided as a rotary-sliding switching element generally requires additional overall length in the extension of the grip area. With a switching device known from DE-A2708981, on the other hand, only the actuation of a single slide switch, that is to say only a simple switching function, is possible.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Mehrfunktionsschalter für elektrische Geräte zu schaffen, der von der Hand betätigbar ist, mit der das Gerät gleichzeitig an seinem Griff gehalten und geführt wird. Dabei soll der Schalter so in den Gerätegriff integriert sein, dass dessen Innenraum möglichst optimal genutzt wird.The present invention is therefore based on the object of providing a multi-function switch for electrical devices which can be operated by hand, with which the device is simultaneously held and guided by its handle. The switch should be integrated in the handle so that its interior is used as optimally as possible.

Diese Aufgabe wird erfindungsgemäss durch einen Mehrfunktionsschalter gemäss Patentanspruch 1 gelöst. In einer vorteilhaften Ausgestaltung weist dieser Schalter die besonderen Kennzeichen des Patentanspruchs 2 auf.This object is achieved according to the invention by a multifunction switch according to claim 1. In an advantageous embodiment, this switch has the special characteristics of claim 2.

Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel:

  • Figur 1 gibt den Längsschnitt durch einen Handhaartrockner wieder,
  • Figur 2 zeigt denselben Haartrockner von der Lufteinlassseite her, und die
  • Figuren 3 bis 5 verdeutlichen Einzelheiten des Schaltbewegungs-Übertragungsgliedes.
The drawing illustrates the invention using an exemplary embodiment:
  • FIG. 1 shows the longitudinal section through a hand hair dryer,
  • Figure 2 shows the same hair dryer from the air inlet side, and the
  • Figures 3 to 5 illustrate details of the switching movement transmission member.

Der Handhaartrockner besteht im wesentlichen aus zwei Gehäuseschalen 1 und 2, einer die Rückseite der Gehäuseschale 1 abschliessenden perforierten Lufteinlasskappe 3, dem Heizregister 4, dem Gebläsemotor 5 mit Lüfterrad 6 und dem Luftauslassgitter 7. Im Griff G ist eine Leiterplatte 8 angeordnet, auf der ein Schiebeschalter 9 und andere zur Regelung des Motors 5 und des Heizregisters 4 notwendige elektrische Bau- und Anschlussteile 10, 11, 12 befestigt sind. Die Innenwandung 14 des aus den Gehäuseschalen 1 und 2 gebildeten Griffes G weist eine kreiszylindrische Form auf, wobei im Bereich des Schiebeschalters 9 ein Schaltbewegungs-Übertragungsglied 15 mit Hebelansatz 16 so gelagert ist, dass es sowohl in Pfeilrichtung P, d. h. in Griff-Längsrichtung, verschiebbar als auch um die Längsachse L des Griffes G verschwenkbar ist.The hand-held hair dryer essentially consists of two housing shells 1 and 2, a perforated air inlet cap 3 that closes off the rear of the housing shell 1, the heating register 4, the blower motor 5 with fan wheel 6 and the air outlet grille 7 Slide switch 9 and other electrical components and connecting parts 10, 11, 12 necessary for controlling the motor 5 and the heating register 4 are fastened. The inner wall 14 of the handle G formed from the housing shells 1 and 2 has a circular cylindrical shape, wherein in the area of the slide switch 9, a switching movement transmission member 15 with a lever shoulder 16 is mounted so that it is in the direction of arrow P, i.e. H. in the longitudinal direction of the handle, is displaceable and also pivotable about the longitudinal axis L of the handle G.

Das Übertragungsglied 15 hat die Form eines Hohlzylinder-Segmentes. Seine gebogene Innenseite 17 weist eine Rippe 18 mit Innenverzahnung 20 auf, die in eine entsprechende Zahnwalze 21 eingreift, die ihrerseits mit der Drehachse des drehverstellbaren elektrischen Bauteils 11 verbunden ist und zur Verstellung des elektrischen Wertes dieses Bauteils 11 dient. Parallel zur Rippe 18 ist ein Steg 19 vorgesehen, der in einen Schlitz 22 am Betätigungsteil 23 des Schiebeschalters 9 eingreift.The transmission member 15 has the shape of a hollow cylinder segment. Its curved inside 17 has a rib 18 with internal toothing 20 which engages in a corresponding toothed roller 21, which in turn is connected to the axis of rotation of the rotationally adjustable electrical component 11 and is used to adjust the electrical value of this component 11. A web 19 is provided parallel to the rib 18 and engages in a slot 22 on the actuating part 23 of the slide switch 9.

Wird nun durch Verschwenken des Hebelansatzes 16 das Übertragungsglied 15 um die Längsachse L des Griffes G verdreht, so wird über die Innenverzahnung 20 die Zahnwalze 21 gedreht und somit der Wert des elektrischen Bauteils 11, beispielsweise eines die Heizleistung des Heizregisters 4 beeinflussenden Potentiometers, verstellt. Unabhängig von der Verstellung des elektrischen Bauteils 11 lässt sich der Schiebeschalter 9 betätigen und hierdurch beispielsweise die Drehzahl des Gebläsemotors 5 verändern, indem das Übertragungsglied 15 in Pfeilrichtung P oder entgegen der Pfeilrichtung P verschoben wird.If the transmission member 15 is now rotated about the longitudinal axis L of the handle G by pivoting the lever shoulder 16, the toothed roller 21 is rotated via the internal toothing 20 and thus the value of the electrical component 11, for example a potentiometer influencing the heating output of the heating register 4, is adjusted. Irrespective of the adjustment of the electrical component 11, the slide switch 9 can be actuated and in this way, for example, the speed of the blower motor 5 can be changed by moving the transmission element 15 in the direction of arrow P or counter to the direction of arrow P.

Dank der erfindungsgemässen Form des dreh-und schiebbaren Übertragungsgliedes 15 in Gestalt eines Hohlzylinder-Segmentes kann sich die Leiterplatte 8, deren obere Schmalseite durch eine Nut 24 am Luftleitring 25 gehalten ist und auf der ausser den Schaltelementen 9, 11 und 21 des Mehrfunktionsschalters auch noch andere elektrische Bauteile 10, 12 des Haartrockners raum- ökonomisch untergebracht sein können, durch den vom Übertragungsglied 15 umfassten Innenraum hindurcherstrecken und trotzdem mit ihrer einen Längskante bis an die Innenwand des Griffes G erstrecken, wo sie an einem Vorsprung 27 fixiert ist. Zwischen der anderen Längskante der Leiterplatte 8 und der Griff-Innenwandung 14 ist ein Spalt 26 vorgesehen, der die ungehinderte freie Verdrehung und Verschiebung des Übertragungsgliedes 15 gewährleistet.Thanks to the shape of the rotatable and slidable transmission member 15 according to the invention in the form of a hollow cylinder segment, the printed circuit board 8, the upper narrow side of which is held by a groove 24 on the air guide ring 25, and on which, in addition to the switching elements 9, 11 and 21 of the multifunction switch, can also be used other electrical components 10, 12 of the hair dryer can be accommodated in a space-efficient manner, extend through the interior space encompassed by the transmission element 15 and nevertheless with it extend a longitudinal edge to the inner wall of the handle G, where it is fixed to a projection 27. A gap 26 is provided between the other longitudinal edge of the printed circuit board 8 and the handle inner wall 14, which ensures the unimpeded free rotation and displacement of the transmission member 15.

Auf seiner Aussenseite weist das Übertragungsglied 15 eine schmale Erhebung 28 auf, die als Index dient und so eine leichte Ablesbarkeit der jeweiligen Stellung des Betätigungsteils 15 gegenüber der Skala 29 ermöglicht.On its outside, the transmission member 15 has a narrow elevation 28 which serves as an index and thus enables the respective position of the actuating part 15 to be read easily relative to the scale 29.

Mit dem erfindungsgemässen Mehrfunktionsschalter und insbesondere seiner in der Zeichnung dargestellten Ausführungsform können durch Verschieben und/oder Verschwenken des Übertragungsgliedes 15 zwei Funktionen eines Gerätes - wie z. B. die Einstellung sowohl der Temperatur als auch der Gebläsedrehzahl eines Haartrockners - einhändig gesteuert werden, ohne dass die Hand ihre Lage am Griff G verändern muss; denn der Daumen der Griffhand liegt fast zwangsläufig am Hebelansatz 16 und kann diesen zusammen mit dem Übertragungsglied 15 verschieben und/oderverschwenken.With the multi-function switch according to the invention and in particular its embodiment shown in the drawing, two functions of a device - such as e.g. B. the setting of both the temperature and the fan speed of a hair dryer - can be controlled with one hand without the hand having to change its position on the handle G; because the thumb of the grip hand is almost inevitably on the lever shoulder 16 and can move and / or pivot it together with the transmission member 15.
