SUSPENSION SYSTEM FOR VERTICAL BLINDS. 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 of 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. A cord, guided through the interior of the length of the track, at and fastened to the first slide, serves to displace 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. The cord for displacing the slides is passed along the track on the side on which the drive rod for adjusting the hook position is located and, in particular, above said rod, and the coupling elements are formed by concertina-like elements which are made of springy material and are fixed to the consecutive slides.
