Abstract

The indicator is used for electric hobs, washing and dishwashing machines etc. Light guide elements (10) are incorporated in the appliance switching knobs (1). The switch has a shutter (16) with a stationary light source (12). Via the light guide elements the knob is provided with a light indication corresponding to its switching state. Each light guide element has preferably inclined deflection surfaces (11, 14) and a conical protrusion (9) which penetrates an aperture (8) in the knob. A single light source may irradiate several light guide elements serving several control knobs.

Es ist ferner nicht mehr neu, von einer einzigen Lichtquelle aus unter Vermittlung von biegsamen Lichtleitern mohrere entfernt angbrachte Objkte anzustrahlen. Der Erfindung liegt die Aufgebe zugrunde, einen Schaltknebel o. dgl. zur einstellung von Betribszuständen an elektrischen Maschinen und Geräten mit einer beweglichen Beleuchtungseinrichtung auszustatten.Furthermore, it is no longer new to be seen from a single light source Mediation of flexible light guides to illuminate more distant objects. The invention is based on the task of setting a switch knob or the like of operating conditions on electrical machines and devices with a moving one Equip lighting equipment.

Die Lösung dieser Aufgabe geht aus den im Hauptanspruch gekennzeichneten Merkmalen hervor. Durch die erfindungsgemäße Einrichtung ergibt sich eine bewegliche Betribsanzeige, die fir die Bdienungsperson in recht anschaulicher Weise die jeweilige einstellung des betreffenden Schaltelementes sichtbar machst.The solution to this problem is based on those characterized in the main claim Features. The device according to the invention results in a movable one Operation notification, which for the service person in a very clear way the respective make the setting of the relevant switching element visible.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen. Die Erfindung ist nachstehend an Hand eines bevorzugten Ausführungsbeispicls beschrieben und in den Zeichnungen näher veranschaulicht.Further features of the invention emerge from the subclaims. The invention is described below with reference to a preferred embodiment and illustrated in more detail in the drawings.

Es zeigen: Fig. 1 ein Schaltknebelgehäuse im Querschnitt, Fig. 2 ein Lichtleitelement im Querschnitt, Fig. 3 einen Schaltknebel mit Lichtleitelement und Beleuchtungseinrichtung in der Schaiterblende eines Iiaushaltsgerätes im Querschnitt in einem Auszug, Fig. 4 eine schematische Darstellung mehrerer Schalt-und ihrer Anzeigeeinrichtungen.They show: FIG. 1 a switch toggle housing in cross section, FIG. 2 a Light guide element in cross section, FIG. 3 shows a switch toggle with light guide element and lighting device in the switch panel of an Iiaushaltsgerätes in cross section in an excerpt, Fig. 4 is a schematic representation of several switching and their Display devices.

Ein in Fig. 1 dargestellter Schalthebel 1 ist aus gepreßtem Kunststoff hergestellt und weist einen kegelstumpfförmig ausgebildeten Hohlkörper 2 auf, dessen obere Ringfläche 3 eine diagonal gerichtete hohle Rippe 4 trägt, die zum Betätigen des Schaltknebels 1 dient. Im Innenraum des Schaltknebels 1 befindet sich eine nach unten überstehende zentrisch angeordnete Hülse 5, die zur Aufnahme einer Schaltwelle 6 (Fig. 3) eines an sich bekannten Schaltwerkes 7 vorgesehen ist.A shift lever 1 shown in Fig. 1 is made of molded plastic produced and has a frustoconical hollow body 2, the upper ring surface 3 carries a diagonally directed hollow rib 4 for actuation of the switch toggle 1 is used. In the interior of the toggle 1 there is one after centrally arranged sleeve 5 protruding at the bottom, which is used to accommodate a shift shaft 6 (Fig. 3) of a known switching mechanism 7 is provided.

Auf der Rippe 4 ist an einer Seite eine Öffnung 8 vorgesehen, in die ein konisch ausgebildeter Ansatz 9 eines Licbtleitelementes 10 hineinragt (Fig. 3).An opening 8 is provided on one side of the rib 4, into which a conical extension 9 of a light guide element 10 protrudes (Fig. 3).

In der Fig. 2 ist das Lichtleitelement 10 im Dctail gezeigt. Das in dcn Schaltknebel 1 einsetzbare Lichtleiter element; 10 besteht aus durchsichtigem Material, z.B.In Fig. 2, the light guide element 10 is shown in detail. This in the switch knob 1 insertable light guide element; 10 is made of clear Material, e.g.

einen Spezialkunsttoff oder Glas.a special plastic or glass.

Die markanten Kennzeichen des Lichtleitelemente 10 sind die schrägen Ablenkflächen 11 und 14 sowie der seitlich nach oben gerichtete Ansatz 9. Die Anordnung der schrägen Ablenkflächen 11 und 14 ist so getroffen, daß ein von einer Lichtquelle 12 ausgehender Lichtstrahl 13 an der nach innen geneigten Ablenkfläche 14 zur Fläche 11 und von letzterer in den Ansatz 9 abgelenkt wird. Der Lichtstrahl tritt dann an der Stirnfläche 15 des Ansatzes 9 aus dem Lichtleitelement 10 heraus (Fig. 2).The distinctive features of the light guide elements 10 are the inclined ones Deflection surfaces 11 and 14 and the laterally upwardly directed approach 9. The arrangement the inclined deflection surfaces 11 and 14 is made so that one of a light source 12 outgoing light beam 13 at the inwardly inclined deflection surface 14 to the surface 11 and is diverted from the latter in the approach 9. The ray of light then occurs at the end face 15 of the extension 9 out of the light guide element 10 (Fig. 2).

Die bereits genannte Lichtquelle 12 (Fig. 3) ist hinter einer Schalterblende 16 nontiert und zweckmäßig mit einem Reflektor 17 zur Bündelung der Strahlen 12 ausgestattet., die durch eine Öffnung 18 einer Schalterblende 16 dem Lichtleitelement 10 zugeführt werden.The already mentioned light source 12 (Fig. 3) is behind a switch panel 16 mounted and expediently with a reflector 17 for focusing the rays 12 Equipped., the light guide element through an opening 18 of a switch panel 16 10 are fed.

Anstelle einer Lichtquelle 12 können zur Beleuchtung mehrerer Schaltknebel 19, 20 gemäß Fig. 4 mittels einer einzigen Lichtquelle 21 auch biegsame Lichtleiter 22, 23 bekannter Bauart verwendet werden, deren jeweilige Mündungen 24, 25 auf die entsprechenden Lichtleitelemente 10 gerichtet sind. Beim Drehen der Schaltknebel 1, 19, 20 treten die Lichtstrahlen im gesamten Drehbereich aus den Öffnungen 8, 26, 27 der Lichtleitelemente 28, 29 aus, so daß der Bedienungsperson in anschaulicher Weise sofort ein Uberblick über die einzelnen SchalL stellungen vermittelt wird. Hierbei ist es gleichgXiltig ob der Schaltknebel 1 um wenige Grade oder über 3600 hinaus verstellt wird. Anstelle des gezeigten Scilaltknebels 1 können auch andere Einstellelemellte beliebiger Bauform benutzt werden, in die ein Lichtleitelement ailgepaßter Bauweise forrnschlüssig eingesetzt werden kann.Instead of a light source 12, several toggles can be used for lighting 19, 20 according to FIG. 4 also flexible light guides by means of a single light source 21 22, 23 of known design are used, the respective mouths 24, 25 on the corresponding light guide elements 10 are directed. When turning the switch knob 1, 19, 20 the light rays emerge from the openings 8 in the entire range of rotation, 26, 27 of the light guide elements 28, 29, so that the operator in clear Way, an overview of the individual switch positions is immediately provided. It does not matter whether the toggle 1 is a few degrees or more than 3600 is adjusted. Instead of the Scilaltknebels 1 shown, others can also Setting elements of any design can be used in which a light guide element a well-fitting design can be used positively.
