  Skala, insbesondere für Radioapparate. 



   Die Erfindung bezieht sich auf eine Skala, insbesondere für Radioapparate "und besteht darin, dass der Skalenzeiger durch eine vom Antrieb der Abstimmittel bewegte Kurbelschleife derart gedreht wird, dass eine Übersetzung ins langsame erfolgt. 



   Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen   Ausführung   im Schaubild dargestellt. 



   Die auf der Vorderwand des Radioapparates angeordnete Skala 1 umfasst einen Zentriwinkel von zirka 90 , während der Drehkondensator, von welchem aus die Skalenzeiger angetrieben werden, in der Regel einen Lamellenausschlag von   1800 besitzt.   Es ist beabsichtigt, einem grossen Winkelausschlag des Drehkondensators   Zeigerausi'1chläge   mit geringerem Winkelausschlag zuzuordnen, damit die Skala flach, leicht ablesbar, stark vergrösserbar und daher bequem auf der Gehäusewand unterbringbar wird. Der Antrieb des Zeigers erfolgt mittels eines Reibungsrades   2,   welches durch einen Drehknopf 9 an der Aussenseite des Radioapparates in Drehung versetzt wird. Das Reibungsrad 2 treibt ein Rad 3 an unter gleichzeitiger Übersetzung der Bewegung ins Langsame. 



   Auf der Achse 4 des Rades 3 sitzen die Rotoren der Drehkondensatoren. Die Scheibe 3 trägt einen Zapfen 5, welcher in einen Schlitz einer Schwingkurbel 6 eingreift, deren Drehpunkt bei 7 liegt. Die Organe 3,   5   und 6 stellen in ihrer Gesamtheit eine schwingende Kurbelschleife dar. Am freien Ende des Schwingarmes 6 ist der Skalenzeiger 8 angeordnet. welcher auf der flachen Skala   1   spielt. Die Kurbelschleife ist ein einfaches und billiges Mittel. um den Winkelausschlag des Drehkondensators verkleinert auf den Winkelausschlag des Zeigers 8 zu übersetzen.

  Scale, especially for radios.



   The invention relates to a scale, in particular for radio sets, and consists in the fact that the scale pointer is rotated by a crank loop moved by the drive of the tuning means in such a way that a translation into slow speed takes place.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment in the diagram.



   The scale 1 arranged on the front wall of the radio set has a central angle of approximately 90, while the rotary capacitor, from which the scale pointers are driven, usually has a blade deflection of 1800. It is intended to assign pointer deflections with a smaller angular deflection to a large angular deflection of the rotary capacitor so that the scale is flat, easy to read, can be greatly enlarged and therefore conveniently placed on the housing wall. The pointer is driven by means of a friction wheel 2, which is set in rotation by a rotary knob 9 on the outside of the radio set. The friction wheel 2 drives a wheel 3 while simultaneously translating the movement into slow motion.



   The rotors of the rotary capacitors sit on the axle 4 of the wheel 3. The disk 3 carries a pin 5 which engages in a slot of a rocking crank 6, the pivot point of which is 7. The organs 3, 5 and 6 represent in their entirety an oscillating crank loop. The dial pointer 8 is arranged at the free end of the oscillating arm 6. which plays on the flat scale 1. The crank loop is a simple and cheap means. in order to reduce the angular deflection of the variable capacitor to the angular deflection of the pointer 8.
