ABSTRACT:
A drive mechanism, particularly for moving and turning the slats of a blind, is disclosed. The drive mechanism comprises a suitable drive element for driving one or the other of a first and a second shaft. Connected between the drive element and the first shaft there is connected a freewheel which is contained between two end positions and is in effect during the rotation of the second shaft in both directions. A clutch is connected between the drive element and the second shaft to automatically decouple the second shaft from the drive element on completion of the freewheel action.
