Abstract

The latching lever (10) is provided with a steel ball (12) which is used as a latching partner for a second latching element. The steel ball is held in a self-locking manner in a pocket in the latching lever which consists of plastic. In this case, it is seated in an attachment (11) on the latching lever, which attachment (11) is like a hemisphere, is shaped like a shell and is provided with spring slots (13) at the edge. <IMAGE>

Description

"Klinkenhebel des Mechanismus eines Selbstschalters""Ratchet lever of the mechanism of a self-switch"

Zusatz zum Patent ........ A.Z. P 30 02 795.3 Die Erfindung betrifft einen Klinkenhebel des Mechanismus eines Selbstschalters mit einer Stahikugel als Verklinkungspartner zu einem zweiten Verklinkungselement.Addendum to the patent ........ A.Z. P 30 02 795.3 The invention relates a latch lever of the mechanism of a self-switch with a steel ball as Latching partner to a second latching element.

Beim Gegenstand des Hauptpatentes ist die Stahikugel auf der Außenseite des einen Endes eines Kontakthebels aufgeschweißt und wirkt mit einem Teil eines Spannhebels zusammen, der an der der Stahikugel zugekehrten Seite einen abgewinkelten flachgeprägten Schenkel aufweist oder dessen flaches Stirnende selbst als Verklinkungsfläche dient. Die Anwendung dieser Verklinkungsart ist auf Mechanismen mit Metalihebeln beschränkt.In the subject of the main patent, the steel ball is on the outside of one end of a contact lever is welded and acts with part of a Tension lever together, the angled on the side facing the steel ball has flat embossed legs or its flat front end itself as a latching surface serves. The application of this type of latching is to mechanisms with metal levers limited.

Die Erfindung bezweckt, die Anordnung des Gegenstandes des Hauptpatentes in der Weise abzuwandeln, daß die Verklinkung mit einer Stahlkugel auch dann möglich ist, wenn der Träger der Stahlkugel nicht aus Metall besteht und somit eine Verschweißung nicht möglich ist. Erfindungsgemäß wird das dadurch erreicht, daß die Stahlkugel in einer Tasche des aus Kunststoff bestehenden Klinkenhebels vorzugsweise selbsthemmend gehalten ist. Die Stahlkugel kann in einem halbkugelartigen, schalenförmigen am Rand mit Federschlitzen versehenem Ansatz des Klinkenhebels gelagert sein. Sie kann aber auch an ein Blech angeschweißt sein, das seinerseits in einer durch Hinterpressung des Klinkenhebels gebildeten Tasche gelagert und durch die Achse des Klinkenhebels gesichert ist.The invention aims to arrange the subject matter of the main patent to be modified in such a way that the latching with a steel ball is then also possible is when the support of the steel ball is not made of metal and thus a weld not possible. According to the invention this is achieved in that the steel ball in a pocket of the plastic latch lever, preferably self-locking is held. The steel ball can be in a hemispherical, cup-shaped am Edge with spring slots provided approach of the latch lever be stored. she can but also be welded to a sheet metal, which in turn in a by pressing the pocket formed by the ratchet lever and supported by the axis of the ratchet lever is secured.

Anhand der Zeichnung sei die Erfindung an zwei Ausführungsbeispielen näher erläutert.The invention is based on two exemplary embodiments with the aid of the drawing explained in more detail.

Fig. 1 zeigt einen Kunststoffklinkenhebel mit einsteckbarem Träger für die Stahlkugel, während in Fig. 2 ein Kunststoffklinkenhebel wiedergegeben ist, der die Stahlkugel selbsthemmend hält.Fig. 1 shows a plastic ratchet lever with an insertable carrier for the steel ball, while a plastic ratchet lever is shown in Fig. 2, which holds the steel ball self-locking.

Der in Fig. 1 dargestellte aus Kunststoff bestehende Klinkenhebel. 1 weist einen parallel zu seinen Hauptflächen verlaufenden Schlitz 2 auf, der auf der einen Seite durch zwei Stege 2a und 2b und auf der anderen Seite durch einen Steg 2c gebildet wird. In dem Steg 2b ist ein Aufnahmeloch 2'b für eine nicht dargestellte Achse vorgesehen. Der Schlitz 2 dient zur Aufnahme eines dreieckförmigen Bleches 3, das in Richtung des Pfeiles 3a in den Schlitz einsteckbar ist. Seine Konturen sind der Schlitzform angepaßt, so daß es in dem Schlitz 2 eng gehalten wird. An einem Ansatz 3b des Bleches 3 ist wie durch Pfeil 4a dargestellt, eine Stahlkugel 4 angeschweißt. Das Blech 3 hat ein Loch 3c, das im eingesteckten Zustand deckungsgleich mit dem Loch 2'b ist, so daß durch die Achse des Klinkenhebels 1 zugleich auch das Blech 3 festgehalten wird.The plastic latch lever shown in FIG. 1. 1 has a slot 2 running parallel to its main surfaces one side by two webs 2a and 2b and on the other side by one Web 2c is formed. In the web 2b is a receiving hole 2'b for a not shown Axis provided. The slot 2 is used to receive a triangular sheet 3, which can be inserted into the slot in the direction of arrow 3a. Its contours are adapted to the shape of the slot so that it is held tightly in the slot 2. At an approach 3b of the sheet 3 is as shown by arrow 4a, a steel ball 4 welded on. The sheet 3 has a hole 3c, which is congruent in the inserted state with the hole 2'b, so that through the axis of the ratchet lever 1 also the Sheet 3 is held.

Bei der Anordnung nach Fig. 2 ist ein aus Kunststoff bestehender Klinkenhebel 10 mit einem halbkugelartigen, schalenförmigen Ansatz 11 versehen, in den eine Stahlkugel 12 selbsthemmend einsetzbar ist. Der schalenförmige Ansatz hat Federschlitze 13 und einen Öffnungsdurchmesser, der etwas kleiner als der Durchmesser der Kugel 12 ist, so daß diese beim Einsetzen eingeschnappt werden muß. Die Kugel ist somit unverlierbar in dem Ansatz 11 gehalten.In the arrangement according to FIG. 2, there is a plastic ratchet lever 10 provided with a hemispherical, bowl-shaped extension 11, into which a steel ball 12 can be used in a self-locking manner. The bowl-shaped extension has spring slots 13 and an opening diameter that is slightly smaller than the diameter of the ball 12 so that it must be snapped into place when inserted. The ball cannot be lost held in the approach 11.
