Abstract

The invention is based on a handle for operating electrical switches, in which the handle is mounted without screws in the apparatus insert of a switch. In this case, the handle consists, for example, of a rotating toggle with an integrally-formed hollow peg which latches by means of an integrally-formed annular bead behind an annular projection in the opening of the apparatus insert. Furthermore, for operation, the hollow peg also has two diametrically opposite recesses by means of which it engages over corresponding projections in the opening of the apparatus insert. A conical construction of the hollow peg and two further slots, which can be pressed together, in the hollow peg simplify the insertion of the handle into the opening in the apparatus insert.

Description

Handhabe für elektrische SchalterHandle for electrical switches

Die Erfindung betrifft die schraubenlose Befestigung einer Handhabe für elektrische Schalter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to the screwless fastening of a handle for electrical switches according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine Handhabe zur Betätigung elektrischer Schalter anzugeben, die in einfacher Weise in deren Geräteeinsatz schraubenlos befestigt werden kann.The invention is based on the object of a handle for actuation Specify electrical switch that is screwless in a simple manner in their device insert can be attached.

Sie wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Mittel gelöst.It is indicated by the characterizing part of claim 1 Means solved.

Weitere Einzelheiten der Erfindung ergeben sich anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist. Es zeigt: - Figur 1 - im Halbschnitt eine Seitenansicht der Handhabe mit angeformtem Hohlzapfen, - Figur 2 - den Geräteeinsatz eines elektrischen Schalters mit erfindungsgemäß befestigter Handhabe, - Figur 3 - den Hohlzapfen ohne Handhabe in einer Ansicht "A" entsprechend der Figur 1, - Figur 4 i eine Einzelheit aus Figur 2.Further details of the invention emerge from the drawing, in which an embodiment is shown. It shows: - Figure 1 - in half section a side view of the handle with molded hollow pin, - Figure 2 - the device insert an electrical switch with a handle attached according to the invention, - Figure 3 - the hollow pin without handle in a view "A" according to Figure 1, - FIG. 4 i a detail from FIG. 2.

Die nach Art eines Drehknebels ausgeführte Handhabe 1 weist einen zentrisch angeformten konusförmigen Hohlzapfen 2 auf.The handle 1, designed in the manner of a rotary knob, has a centrally formed cone-shaped hollow pin 2.

Auf der Außenseite seiner Wandung ist eine Ringwulst 3 angeformt. In der Wandung sind jeweils diametral einander gegenüberliegende Schlitze 4 und Ausnehmungen 5 vorgesehen.An annular bead 3 is formed on the outside of its wall. In the wall there are diametrically opposed slots 4 and Recesses 5 are provided.

In dem Geräteeinsatz 6 ist zentrisch eine Öffnung 7 für den Hohlzapfen 2 vorgesehen. An der Innenseite dieser Öffnung 7 sind einander diametral gegenüberliegende Ansätze 8 materialeidheitlich angeformt, die zum Eingriff mit den Ausnehmungen 5 im Hohlzapfen 2 dienen. Wie in Figur 4 einer Einzelheit aus Figur 2 ersichtlich, befindet sich in der Öffnung 7 oberhalb der Ansätze 8 ein Ringvorsprung 9 für die Abstützung der Ringwulst 3.In the device insert 6 is centrally an opening 7 for the hollow pin 2 provided. On the inside of this opening 7 are diametrically opposed to each other Approaches 8 integrally formed in terms of material, which for engagement with the recesses 5 serve in the hollow pin 2. As can be seen in Figure 4 of a detail from Figure 2, is located in the opening 7 above the lugs 8, an annular projection 9 for the Support of the annular bead 3.

Beim Eindrücken des Hohlzapfens 2 der Handhabe 1 in die Öffnung 7 des Geräteeinsatzes 6 werden die elastischen Schlitze 4 zusarrimengedrückt und der Hohlzapfen soweit vorgeschoben, bis seine Ringwulst 3 hinter den Ringvorsprung 9 greift. Dabei weiten die elastischen Schlitze wieder auf und bilden für die axial Richtung der Handhabe eine zuverlässige Befestigung. Dadurch, daß der Hohlzapfen konusförmig ausgebildet ist, ist ein leichtes Zusamsenfügen von Handhabe und Geräteeinsatz möglich.When the hollow pin 2 of the handle 1 is pressed into the opening 7 of the device insert 6, the elastic slots 4 are pressed together and the The hollow pin is pushed forward until its annular bead 3 is behind the annular projection 9 engages. The elastic slots widen again and form for the axially Direction of the handle a reliable attachment. Because the hollow pin Is conical, an easy joining of handle and device insert possible.
