Description
Die Erfindung betrifft einen versenkbaren Drehknebel nach dem Oberbegriff des Patentanspruches 1.The invention relates to a retractable rotary knob according to the preamble of
Aus der DE-C-27 01 017 ist ein versenkbarer Drehknebel dieser Art bekannt.From DE-C-27 01 017 a retractable rotary knob of this type is known.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den versenkbaren Drehknebel der bekannten Art durch eine optische Anzeigeeinrichtung zu verbessern, um das Erkennen bzw. Ablesen der Einstell-Markierungszeichen sowie der Betriebsanzeige auch bei mangelhafter Raumausleuchtung oder beeinträchtigter Sehschärfe der Bedienungsperson zweifelsfrei zu ermöglichen.Based on this prior art, the invention has for its object to improve the retractable rotary knob of the known type by an optical display device in order to recognize or read the setting markings and the operating display even with poor room lighting or impaired visual acuity of the operator enable.
Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruches 1 zu entnehmen.The solution to this problem according to the invention can be found in the characterizing part of
Zweckmäßige weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further developments of the subject matter of the invention are specified in the subclaims.
Durch die Erfindung wird ein versenkbarer Drehknebel mit beleuchteten Einstell-Markierungszeichen geschaffen, der auch bei ungünstigen Lichtverhältnissen und mangelhafter Sehschärfe ein deutliches Erkennen der Einstell-Markierungszeichen zuläßt. Weiterhin zeichnet sich dieser versenkbare Drehknebel durch eine gleichmäßige Lichtverteilung im gesamten Bereich der Einstell-Markierungszeichen aus. Ferner kann dadurch eine zusätzliche optische Betriebsanzeige entfallen, weil durch Aufleuchten der Markierzungszeichen gleichzeitig die Inbetriebnahme des betreffenden Verbrauchers signalisiert wird.The invention provides a retractable rotary toggle with illuminated setting marking characters, which allows the setting marking characters to be clearly recognized even under unfavorable lighting conditions and poor visual acuity. Furthermore, this retractable rotary stands out gag through a uniform light distribution in the entire area of the setting markers. Furthermore, an additional optical operating display can be omitted because the start-up of the relevant consumer is signaled at the same time by the lighting up of the markings.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser näher erläutert.An embodiment of the invention is shown in the drawing and will be explained in more detail with reference to this.
Es zeigen:
- Fig. 1 eine Schalterblende für ein Haushaltsgerät mit einem versenkten Drehknebel und optischer Anzeigeeinrichtung im Schnitt,
- Fig. 2 und 3 Ansichten von zwei unterschiedlichen Ausführungsmöglichkeiten der Anzeigeeinrichtung.
- 1 is a switch panel for a household appliance with a countersunk rotary knob and optical display device in section,
- 2 and 3 are views of two different possible embodiments of the display device.
Mit 1 ist die die Vorderseite einer Schalterblende für ein Haushaltsgerät bildende Blendenplatte bezeichnet, die beim dargestellten Ausführungsbeispiel aus einem durchsichtigen Material, z.B. Glas, besteht. Die Blendenplatte 1 ist dabei von der Rückseite her so abgetönt bzw. eingefärbt, daß lediglich um eine Knebelöffnung 2 herum ein durchsichtiger Ringbereich 3 verbleibt. Die Knebelöffnung 2 in der Blendenplatte 1 wird von einem versenkbaren Drehknebel 4 eingenommen, der als Hohlzylinder ausgebildet ist und der in seiner versenkten Stellung (Ruhestellung) mit der Vorderseite der Blendenplatte 1 fluchtet. Der Drehknebel 4 sitzt gleit- bzw. verschiebbar auf einer Knebelwelle 5, die über eine Steckverbindung 6 mit einer Schalt- oder Regeleinrichtung 7 in Wirkverbindung gebracht ist. im Innern des Drehknebels 4 ist eine nicht sichtbare Druckfeder untergebracht, die sich gegen die im Drehknebel endende Stirnseite der Knebelwelle 5 abstützt und mit Hilfe derer durch ein kurzzeitiges Antippen des Drehknebels 1 dieser aus seiner versenkten Raststellung in die ausgefahrene Betriebsstellung gedrückt wird, in der die Schalt- oder Regeleinrichtung 7 eingestellt werden kann.1 designates the front plate of a switch panel for a household appliance, which in the illustrated embodiment is made of a transparent material, e.g. Glass. The
Hinter die Rückseite der Blendenplatte 1 befindet sich ein den versenkbaren Drehknebel 4 in sich aufnehmender zylinder- bzw. topfartiger Reflektorkörper 8, der in nicht dargestellter Weise durch eine Steck- bzw. Laschenverbindung an einem die Blendenplatte 1 tragenden Blendenrahmen 9 gehaltert ist. Der Reflektorkörper 8 weist eine zur Blendenplatte 1 hin offene ringförmige Reflektorkammer 10 auf, die durch Anformen gebildet ist, so daß Reflektorkörper und Reflektorkammer einstückig ausgebildet sind. Die zur Rückseite der Blendenplatte 1 hin gerichtete offene Seite der Reflektorkammer 10 ist mit einem lichtdurchlässigen bzw. lichtdurchscheinenden Ringkörper 11, der vorzugsweise aus einem Prismenglas bzw. einem Glasring mit nach außen angeordneter prismenartiger Oberfläche besteht, abgedeckt. In der Reflektorkammer 10 ist ein Leuchtkörper untergebracht, der aus mehreren um deren Umfang verteilt angeordneten einzelnen Glimmlampen 12,12',12",12"' oder aus einer Glimmlampe mit mehreren kreisbogenförmigen Leuchtglaskolben 13,13', 13" besteht. Bei Verwendung von mehreren einzelnen Glimmlampen als Leuchtkörper sind diese fester Bestandteil eines aus Hartpapier bestehenden Isolierringkörpers 14, der an der Rückseite der Reflektorkammer 10 angelegt ist. Die Glimmlampen 12,12',12",12"' sind senkrecht vom Isolierringkörper 14 abstehend angeordnet. Zum Einführen der Glimmlampen in die Reflektorkammer 10 besitzt diese rückseitig entsprechende Einführungsöffnungen 15. Der Isolierringkörper 14 trägt auch die elektrische Schaltung für die Glimmlampen, die in bekannter Weise als gedruckte Schaltung ausgeführt ist.Behind the rear of the
Mit den die Drehbewegung des Drehknebels 4 übertragenden Teilen 5 bzw. 6 ist ein mit Markierungen versehener Schalterstellungsanzeiger 16 aus lichtdurchscheinendem Material gekoppelt, dessen ringartige Markierungsfläche 17 zwischen dem lichtdurchlässigen Ringkörper 11 der Reflektorkammer 10 und der Rückseite der Blendenplatte 1 angeordnet ist. Vor der Markierungsfläche 17 befindet sich der durchsichtige Ringbereich 3 der Blendenplatte 1. Der Schalterstellungsanzeiger 16 ist ebenfalls zylinder- oder topfartig ausgebildet und so ausgelegt, daß der Reflektorkörper 8 diesen mit Spiel in sich aufnimmt.With the
