Description

  

      Anzeigevorrichtung    für die Stellung des     Stellgriffes    elektrischer Geräte,  insbesondere für     Elektroherde       Die Erfindung     betrifft    eine     Anzeigevorrichtung     für die Stellung des     Stellgriffes    elektrischer Geräte,  insbesondere für Elektroherde oder dergleichen, die  auch aus einer gewissen Entfernung vom Herd und  bei schlechten Lichtverhältnissen leicht die Einstellung  des Herdes erkennen lassen soll.

   Erfindungsgemäss  führen von den einzelnen Bereichen wenigstens einer       Anzeigeskala    optische Leiter zu einer von dem Stell  griff der Anzeigevorrichtung bewegten Blende, die die       Lichteintrittsstirnen    nach Massgabe der Griffstellung  gegen eine Lichtquelle abschirmt bzw. für die Licht  quelle freigibt. Ein besonderer Vorteil einer solchen  Anzeigevorrichtung besteht darin, dass die Lichtaus  trittsstellen der optischen Leiter in einer anders ver  laufenden Reihe als die     Lichteintrittsstellen    angeord  net werden können. So können z. B. die Austrittsstellen  in einer Geraden, die Eintrittsstellen in einem Kreis  bogen     aneinandergereiht    sein.

   Man kann dann für die  Einstellung einen einfachen Drehgriff benutzen, der nur  eine Bohrung für die Durchführung durch die Herd  wand benötigt und kann dabei eine Anzeige in     Form     geradliniger Balken oder dergleichen erzielen, wie sie  sich sonst nur bei     Schiebergriffen    ergibt, für deren  Durchführung aber Schlitze und die entsprechenden       Abdeckmettel    erforderlich sind. Ein Getriebe, das die  Drehbewegung des Handgriffes in eine Längsverschie  bung der     Anzeigebalken    oder dergleichen umformt,  ist nicht nötig, da es durch entsprechende Anordnung,  Krümmung usw. der optischen Leiter in seiner Wir  kung ersetzt     wird.     



  Ein Ausführungsbeispiel der Erfindung ist in der  Zeichnung dargestellt.  



       Fig.    1 zeigt einen Ausschnitt aus einem Schaltpult  eines Elektroherdes;         Fig.    2 zeigt einen Schnitt nach der Ebene     A-B    der       Fig.    1.  



  Auf den Schaltpult S ist ein Drehgriff 1 mit einer  Welle 2 gelagert, die zur Steheinrichtung des Herdes  führt. Auf der Welle sitzen drei     Blendenscheiben    2',  die     Lichteintrittsstirnen    3 von optischen Leitern 4,  beispielsweise Stäben aus durchsichtigem Kunststoff,  gegen eine Lichtquelle 5 mit     Reflektor    6 abschirmen  können. Die     Lichtaustrittsstirnen    7 dieser Leiter sind  in Schlitzen 8 der     Schaltpultwand        aneinandergereiht,     und zwar sind drei parallele Reihen angeordnet. Die  Eintrittsstirnen 3 liegen dagegen auf einem     Kreisbogen     verteilt.

   Die Blenden der Scheiben 2' sind derart  gegeneinander versetzt, dass bei der Drehung des  Griffes 1 von der      Aus -Stellung    zuerst die     Licht-          austrittsstirnen    in dem obersten Schlitz 8 nachein  ander aufleuchten, dann die der folgenden Schlitze.  Die drei Schlitze sind den Bereichen  Wärmen ,   Kochen  und  Braten  zugeordnet.



      Display device for the position of the handle of electrical devices, especially for electric stoves The invention relates to a display device for the position of the handle of electrical devices, especially for electric stoves or the like, which can easily recognize the setting of the stove even from a certain distance from the stove and in poor lighting conditions should.

   According to the invention lead from the individual areas of at least one display scale optical conductors to a moved by the control handle of the display device screen, which shields the light entry foreheads according to the grip position against a light source or releases it for the light source. A particular advantage of such a display device is that the light exit points of the optical conductors can be arranged in a different row than the light entry points. So z. B. the exit points in a straight line, the entry points in a circle arc strung together.

   You can then use a simple twist grip for setting, which only needs a hole for the implementation through the stove wall and can achieve a display in the form of straight bars or the like, as it otherwise only occurs with slide handles, but slots for implementation and the corresponding cover sheets are required. A gear that transforms the rotary movement of the handle in a longitudinal displacement environment of the indicator bar or the like is not necessary, since it is replaced by appropriate arrangement, curvature, etc. of the optical conductor in its action.



  An embodiment of the invention is shown in the drawing.



       1 shows a section from a control panel of an electric cooker; FIG. 2 shows a section along the plane A-B of FIG. 1.



  On the control panel S, a rotary handle 1 is mounted with a shaft 2, which leads to the standing device of the stove. Sitting on the shaft are three diaphragm disks 2 ′, which can shield the light entry ends 3 of optical conductors 4, for example rods made of transparent plastic, from a light source 5 with reflector 6. The light exit ends 7 of these conductors are lined up in slots 8 of the control panel wall, namely three parallel rows are arranged. The entry foreheads 3, however, are distributed on an arc.

   The diaphragms of the panes 2 'are offset from one another in such a way that when the handle 1 is turned from the off position, first the light exit foreheads in the topmost slot 8 light up one after the other, then those of the following slots. The three slots are assigned to the areas of heating, cooking and frying.
