Abstract: A self-contained drive mechanism for slatted blinds has a housing with spaced apart cylindrical bearings, and a pair of interfitting bushes disposed in the housing and supported on the cylindrical bearings, and with the connection between the bushes including a flexible torque limiting drive to prevent overloading the slat mechanism.

Abstract: Suspension system for vertical blinds, comprising a track, one side of which is partially open, a non-circular drive rod for adjusting the position of hooks, a number or slides each provided with a sleeve having an internal shape that is adapted to suit the section of the non-circular rod and externally provided with a worm wheel which interacts with a second worm wheel for a suspension hook, in a manner such that the slides are movable along the drive rod and the suspension hooks can be rotated by rotating said drive rod with the aid of a cord placed over a pulley. Means, also operated by a cord pulley with cord, are present for displacing the slides in the longitudinal direction of the track for pushing the blinds to be suspended in and out, respectively. The slides are mutually connected by coupling elements by which the mutual distance of the slide is limited.
