Description

Griff für elektrische Drehschalter, der durch eine U-förmige Feder auf der Schalterachse festgehalten wird, --------------------------------------------------- Drehgriffe von Schaltern, wie sie in der elektrischen Hausinstallation zur Anwendung komment werden vielfach mit einer Schraube auf der Achse des Schalters befestigt, die entweder in Richtung der Schalterachse oder senke recht dazu angeordnet ist. Es gibt aber auch Fälle, in denen es wünschenswert ist, die Griffe ohne Werkzeug, d. h. ohne Schraubenzieher, befestigen zu können.Handle for electric rotary switches, which is held by a U-shaped spring on the switch shaft, -------------------------------------------------- - Knobs of switches, like those in the electrical House installation to the application will be commented many times fastened with a screw on the axis of the switch, which is arranged either in the direction of the switch axis or sink right to it. But there are also cases in which it is desirable to be able to attach the handles without tools, ie without a screwdriver.

Eine einfache Methode besteht darin, dass man die Schalterachse schlitzt und das Achsende hierdurch federnd gestaltet Der Griff kann dann auf die Achse aufgesteckt werden. Diese Einrichtung erfordert abereine besondere Ausbildung der Schalterachse.One simple method is to slit the switch shaft and the axle end is designed to be resilient as a result. The handle can then be attached to the axle will. However, this facility requires a special design of the switch axis.

Bei einer anderen bekannten Anordnung ist in der Schalterachse eine Rille vorhanden, in welche ein in dem Griff befindlicher federnder Sprengring eingreift.In another known arrangement in the switch axis is a There is a groove in which a resilient snap ring located in the handle engages.

Diese Einrichtung bedingt aber eine verhältnismässig hohe Abzugskraft, so dass der Griff beim Abziehen beschädigt werden kann.However, this device requires a relatively high pull-off force, so that the handle can be damaged when pulling it off.

Die Erfindung besteht in einer Unförmig gebogenen Feder aus Runddraht oder Federblech, deren U-förmig gebogene Schenkel gegen die Innenwandung des Griffs loches drücken. Hierbei durchdringt die Feder mit ihrem U-Steg die Schalterachse quer zu ihrer Längsachse.The invention consists in a shapelessly bent spring made of round wire or spring plate, the legs of which are bent in a U-shape against the inner wall of the handle press hole. Here, the spring penetrates the switch axis with its U-bar transverse to its longitudinal axis.

Das Loch des Griffes ist zu diesem zwecke mit zwei nischenartigen Erweiterungen versehen, in denen sich die Federschenkel bewegen können. Die Enden der USchenkel sind gegeneinander abgebogen und greifen in ein weiteres Querloch der Schalterachse ein.The hole in the handle has two niche-like shapes for this purpose Provided extensions in which the spring legs can move. The ends the U thigh are turned against each other and grab another Cross hole of the switch axis.

Die Abb. 1 zeigt einen Schaltergriff im Längsschnitt mit der erfindungsgemässen eder. In der Abb. 2 ist das Loch in dem Schaltergriff dargestellt. Die Abb, 3 zeigt die U-förmig gebogene Feder mit ihren beiden abgebogenen Enden.Fig. 1 shows a switch handle in a longitudinal section with the inventive eder. In Fig. 2 the hole in the switch handle is shown. Fig, 3 shows the U-shaped bent spring with its two bent ends.

In der Schalterachse 1 (Abb 1) wird die Unförmig gebogene Feder 2 in dem Querloch 3 der Achse I festgehalten, wobei der Steg 4 der Feder 2 das Loch 3 durchdringt. Die beiden Schenkel 5 und 6 der Feder 2 drücken gegen die Wandungen des Griffes 7. Damit die beiden Schenkel 5 und 6 sich frei bewegen können, sind die nischenartigen Erweiterungen 8 und 9 (Abb, 2) in dem Loch lo vorgesehen. Damit die Feder 2 nicht von der Achse 1 abfallen kann, sind die Enden 5 und 6 an ihren vorderen Enden 11 und 12 (Abb. 3) gegen*" einander abgebogen und greifen mit diesen in ein weiteres Querloch 13 ein*In the switch axis 1 (Fig 1) the misshapen bent spring 2 held in the transverse hole 3 of the axis I, the web 4 of the spring 2 being the hole 3 penetrates. The two legs 5 and 6 of the spring 2 press against the walls of the handle 7. So that the two legs 5 and 6 can move freely, are the niche-like extensions 8 and 9 (Fig, 2) provided in the hole lo. In order to the spring 2 cannot fall off the axis 1, the ends 5 and 6 are at their front ends 11 and 12 (Fig. 3) bent against each other and grip with these into another transverse hole 13 *
