  • Patent number: 4552195
    Abstract: The strip curtain has a plurality of glide elements which are guided by a curtain rod and connected with each other by separation-limiting devices. The free hanging curtain strips are suspended from vertical pivot axes with limited excursion. Operation of the pivot axis is by a pinion which engages a bead chain that is slidably guided by the curtain rod. The pinion is connected to the pivot axis by a worm drive, a slip coupling being provided between the pinion and the worm drive. The bead chain serves as common drive for producing pivotal movement and sliding movement of the curtain strips. The strip curtain is of simple construction and therefore reliable in operation and inexpensive and suitable for mass production.

  • 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.

  • Patent number: 4116257
    Abstract: Strip curtains having sliding hangers guided in a curtain track and rotatable about the vertical to which free-hanging curtains are removably attached. The sliding hangers are united by connecting members, together forming an articulated series of links capable of being extended and folded. The sliding hangers are juxtaposed and oriented transversely to the curtain track in the folded condition of the series of links and are positioned approximately in the vertical plane defined by the track in the extended condition of the series of links. The curtain panels are snapped onto the sliding hangers.

  • Patent number: 4102381
    Abstract: A non-stretchable actuating tape moves in the curtain track, engaged by a sprocket wheel attached to the pivot shaft of each sliding element supporting a curtain strip. A slip coupling and stop member limits pivoting. A beaded chain limits spacing of sliding elements.
