Abstract

Die Erfindung betrifft eine Kupplung für eine Wickelwelle eines Springrollos mit einer Achse (12) und einem relativ zur Achse (12) drehbaren und aufgrund seiner relativen Drehung zur Achse (12) mittels einer mit einem Schaltstift (14) zusammenwirkenden Kulisse (24,25) verschieblichen Kupplungselement (15). Um die Zahl der Teile und damit die Fertigungskosten zu reduzierten, ist die erfindungsgemäße Kupplung dadurch gekennzeichnet, daß zwei einander gegenüberliegende Kulissen (24,25) vorgesehen sind, zwischen denen der Schaltstift (14) hin- und her schaltet.

The invention relates to a coupling for a winding shaft of a roller blind having an axis (12) and a relative to the axis (12) rotatable and due to its relative rotation to the axis (12) by means of a with a switching pin (14) co-operating link (24,25) slidable coupling element (15). In order to reduce the number of parts and thus the manufacturing costs, the coupling according to the invention is characterized in that two opposing scenes (24,25) are provided, between which the switching pin (14) switches back and forth.
