  • Patent number: 9801486
    Abstract: A drapery system that operates by rotating a rod having one, or a pair of left hand twist helical grooves, and one or a pair of right hand twist helical grooves, where the left hand twist and right hand twist helical grooves cross one another in equal spaced alignment across the length of the rotating rod. A plurality of idler rings and at least one driver ring are positioned around the drapery rod. The idler rings have a smooth interior surface whereas the driver rings include at least one tooth that engages a helical groove of the rotating rod. As the rotating rod is rotated, the driver ring is driven across the length of the rotating rod, thereby opening and closing the system. The system also includes a mounting bracket allows for extending the drapery past the inward edge of the inward most ring.

  • Patent number: 7322395
    Abstract: Disclosed is a tambour door comprising a door leaf that can be rolled up. The door comprises a vertical roller frame for receiving the door leaf, a sliding bar, to which the rollable door leaf is fixed, and an upper horizontal guide rail, in which the sliding bar is displaceably mounted. The invention facilitates a particularly simple, space-saving, modular construction. The rear face or external face of the roller frame is fixed to a wall and the guide rail is configured as a floating guide rail, which is fixed on one side at least indirectly to the roller frame and on the other side in a fixing element that is fastened at least indirectly to a wall. The door can be used as a lavatory door, or in situations requiring privacy protection for a door opening that economizes on space as much as possible.

  • Patent number: 5467808
    Abstract: An automatic blind or curtain suspension system is described comprising a blind headrail 10 or curtain pole carrying at least one suspension device 28 arranged for movement relative to the headrail 10 or pole towards and away from a stop 48 to open and close the blind or curtain. An electric motor 44a is coupled to the suspension device 28 and operable to cause it to move relative to the headrail 10 or pole. The system includes compression springs 50 adapted to take up additional drive from the motor once motion of the suspension device 28 is retarded by the stop 48. An automatic controller 12 is provided which detects a monotonic increase in current to the motor 44a associated with drive from the motor 44a being taken up by the springs 50 and interrupts current to the electric motor 44a when the increase in motor current is detected. The controller may also keep track of the position of the suspension device 28 and store its position when the increase in current is detected.
