Abstract: A wirelessly controllable, motorized and battery powered drapery apparatus is presented having a rotatable drive element having a guide structure in its surface. The drapery apparatus includes brackets that house conventional batteries which power the apparatus. The brackets connect to a motor assembly which houses a motor and a motor controller. The rotatable drive element includes at least one key feature in its hollow interior. The guide structure is indexed to the key feature such that two rotatable drive elements can be connected together in such a manner that the guide structure is aligned on the two rotatable drive elements ensuring that the shade material opens and closes evenly.

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.

Abstract: A window covering is disclosed that includes a first rail, window covering material adjacent the first rail, at least one lift cord extending through the window covering material to the headrail, a plurality of pulleys positioned adjacent the first rail, at least one spring motor adjacent the first rail, at least one spring motor cord extending from the one or more spring motors and a deformable connector attached to one or more spring motor cords and one or more lift cords. The connector is deformable to a size and shape sufficient for the connector and one or more spring motor cords to pass along at least one of the pulleys during movement along a cord path defined by one or more of the pulleys.

Abstract: The present invention relates to a fixing structure of the cord winding mount for window curtain, comprising a stationary block, an arbor gear, a winding drum, a positioning cover plate and a movable cover.

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.

Abstract: A device for supporting a curtain including a hollow rail which includes a length, a narrowed opening, and an upper attachment surface for attaching the rail to a horizontal support surface. A helically wound spring is disposed inside the hollow rail and includes a plurality of turns, a fixed end, and a moveable end. A plurality of curtain holding members are disposed on the plurality of turns wherein the plurality of holding members can move within the narrowed opening. The hollow rail is attachable via the upper attachment surface to the horizontal support surface so as to support a curtain along the length of the hollow rail.

Abstract: A fully automatic motor driven curtain drawing apparatus which is of a simple, but highly reliable design and one which can be easily adjusted to accommodate windows of widely differing sizes. They can be opened either manually or by an electric motor which can be remotely energized. A timer and a sensor are operably connected to the electric motor and function to energize the motor either at a predetermined time or in response to the sensor sensing daylight and dark.

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.
