Description
Sperrschiebers vorgesehen ist. Letzterer trägt eine Steuerkurve 6 für einen vorzugsweise als Kugel ausgebildeten Rotationskörper?. Dieser liegt gleichzeitig in einer zweiten Steuerkurve 8, die in dem Gelenkteil 3 vorgesehen ist.Lock slide is provided. The latter wears one Control cam 6 for a body of revolution, preferably designed as a ball. This is at the same time in a second control cam 8 which is provided in the joint part 3.
Wie die Zeichnung erkennen laßt, weist der Sperrschieber 5 einen Sperrzahn auf, der mit der Zahnung 2 des Gelenkteils 1 zusammenwirkt. Außerdem steht er unter der Wirkung einer Druckfeder 9, deren Wirkung durch ein Zugelement 10 aufgehoben werden kann.As can be seen from the drawing, the locking slide 5 has a locking tooth which is connected to the toothing 2 of the joint part 1 cooperates. He is also under the action of a compression spring 9, whose Effect can be canceled by a tension element 10.
