ABSTRACT:
A mechanism for the roller of a roller blind, in which a housing has rotatably mounted therein a pulley over which a ball cord, passes, with two pieces of cord hanging down, one from each side of the pulley. The balls of the ball cord can be engaged in one of two U-shaped slots, to lock the cord. The U-shaped slots are each formed in a locking element which is designed as a component which can be fastened to the housing in either of two different positions, the locking part being arranged on the locking element in such a way that, in one or other of the two different positions, it always interacts with one or the other of the pieces of cord hanging down.
