  • Patent number: 4850415
    Abstract: The invention relates to a gathering device for raising and lowering a gathered curtain, having gathering rollers distributed along the horizontal length of the curtain, the rollers are provided with pull elements that can be wound up for raising and unwound for lowering the gathered curtain. The gathering rollers are rotatable by a common drive element about their roller axles. The roller axles of the gathering rollers in the vicinity of the ceiling extend crosswise to the longitudinal direction of the curtain. The gathering rollers are also connected to coaxial drive rollers in a manner fixed against relative rotation. The drive rollers associated with the gathering rollers are actuated by the drive element, which is embodied such that it can be wound up and which extends onward from one drive roller to the next drive roller, this one drive element acting in a cable-like or chain-like fashion on the drive rollers.

  • Patent number: 4227564
    Abstract: The curtain track with a traverse cord has at least one guidance channel in which the curtain hangers to which the curtain is to be attached are longitudinally freely movable. The cord is also positioned within this track and is led over turn-around or exit rollers at the end of the track. The curtain hangers are in frictional engagement with the cord, so that they can be actuated by the cord but stop when a resistance arises, whereupon the cord slips past them. The curtain can be operated both with the traverse cord and also by throwing.
