ABSTRACT:
A worm drive for setting the angular position of vertical slat blinds comprising a vertical axis or shaft arranged inside a slat carrier housing and carrying a pinion torsionally connected thereto and having its end side joined to a slat. A worm rotatable by a drive shaft is in drive engagement with the pinion. This worm drive is characterized by a worm having an axial center opening that, given significantly simplified assembly and reduced structural depth of the slat carrier housing, is held by a snap-on sleeve on a projection of the slat carrier housing shaped like a connecting piece. The worm is provided with an inside dentation that is in engagement with cams arranged at the outside circumference of the snap-on sleeve and thus forms a friction clutch that allows a hamrless overturning of the worm as a consequence of the limited transmission of torque.
