Bei Anordnung einer Rast mit Rollenhebel,When arranging a detent with roller lever,

welche einen festen Drehpunkt besitzen, ergibt sich bei geringer Länge dieses Hebels bei den verschiedenen Drehrichtungen ein verschieden großer Widerstand.which have a fixed pivot point, results in a short length of this lever at resistance to different directions of rotation.

Bezeichnet in Fig. ι R die Zugkraft der Feder, bezogen auf den Rollenmittelpunkt, so ist bei Rechtsdrehung des Sternes α eine Kraft P1 und bei Linksdrehung eine Kraft P2 In Fig. Ι R denotes the tensile force of the spring, based on the roller center point, a clockwise rotation of the star α is a force P 1 and a counterclockwise rotation is a force P 2

ίο erforderlich, um die Federkraft zu überwinden. Aus der ungleichen Größe dieser beiden Kräfte ergibt sich der oben erwähnte, verschieden große Widerstand. Außerdem verhindert die durch die große Normalkomponente N1 hervorgerufene Reibung den leichten Gang der Anordnung. Diese Nachteile sind bei nachstehender Anordnung vermieden. Der Rollenhebel besitzt hierbei keinen festen Drehpunkt, sondern ist symmetrisch durch zwei Federn .F.F1 auf zwei Stifte S1 S.2 gelagert. Durch diese Symmetrie wird ein vollständig gleicher Widerstand für beide Drehrichtungen des Sternes erzielt.ίο required to overcome the spring force. The unequal size of these two forces results in the above-mentioned, differently large resistance. In addition, the friction caused by the large normal component N 1 prevents the arrangement from moving easily. These disadvantages are avoided with the following arrangement. The roller lever does not have a fixed pivot point, but is symmetrically supported by two springs .FF 1 on two pins S 1 p. 2 . Due to this symmetry, a completely equal resistance is achieved for both directions of rotation of the star.

Ferner ermöglicht die elastische Anordnung der Rollenhebel einen leichten Gang der Rast.In addition, the elastic arrangement of the roller levers enables easy movement of the detent.

Die Ausführung wird praktisch so getroffen, daß zwei gegenüberliegende Rollenhebel durch zwei Federn gemeinsam angezogen werden.The execution is made so that two opposite roller levers are tightened together by two springs.
