Abstract:
A window shade comprises first and second rails, and a shading structure and a suspension cord connected between the first and second rails. The second rail includes a resistance balancing unit and a cord winding unit to which the suspension cord respectively connects. The resistance balancing unit comprises a housing having an abuttal surface, a pulley pivotally connected with the housing, and a torsion spring. The pulley has a winding portion around which the suspension cord is wrapped, and a shaft portion extending coaxial to the winding portion from a side thereof. The torsion spring is tightly mounted around the shaft portion and has at least one end. The pulley when rotating in one direction drives the end of the torsion spring to push against the abuttal surface of the housing, whereby the torsion spring loosens to allow rotation of the pulley relative to the torsion spring.
Abstract:
An actuator mechanism for window coverings, such as, Venetian blinds that eliminates the use of pull cords and tilting wands is provided. The actuator mechanism includes a stop member engageable with at least one of the slats to stop tilting movement thereof and a clutch arrangement between a drive axle and a tilt control mechanism, responsive to the stop member engaging at least one of the slats, to disengage the tilting force applied to a ladder cord supporting the slats.
Abstract:
A control mechanism provides a clutch module for selective locking and unlocking of a drive shaft used to retract and extend the shade element between storage and extended positions. The clutch module includes a reciprocator element that engages a key extending from an outer surrounding housing. A locking member between the reciprocator element and a coupling element carried by the drive shaft selectively locks and unlocks rotational coupling between the reciprocator element and the coupling element, thus selectively locking and unlocking the drive shaft. A cushioning mechanism, a unidirectional dampening or frictional deceleration is provided for the drive shaft. The cushioning mechanism includes an impeller or rotor immersed in a cushion medium that impedes rotation of the rotor, and hence the drive shaft to which the rotor is coupled.
Abstract:
A control mechanism for use in a window covering to control the raising and lowering of one or more control cords to open and close light blocking elements is provided. The control mechanism includes a frame which is mountable within a support structure, such as the headrail, and includes as a first abutment stop and a second abutment stop. The position of the frame of the control mechanism is slidingly adjustable relative to the head rail to accommodate different width window spaces.
Abstract:
A window covering including a plurality of panels vertically suspended from a vertical securement member is provided. The plurality of panels is secured with the securement member about an upper transverse portion of the panels at spaced intervals along the securement member. The closure rows are convertible between different configurations by detaching the lower transverse portions of the closure rows from the suspension members.

Abstract:
A window covering having a plurality of panels comprising a head rail and a plurality of panels suspended from the head rail by a securement member and at least one opening member is provided. Each of the plurality of panels is collapsible and includes a pair of opposed longitudinal regions. A bottom rail may also be provided and suspended from the head rail such that the plurality of panels are located between the head rail and the bottom rail.
Abstract:
Cellular panels may be suspended from head rails through the use of a rigid strip of material positioned with the cellular panel. In order to securely position the rigid strip and cellular panel with respect to the head rail, a securement insert is provided. The securement insert includes a cap securable with the head rail by an interference fit and a slot member including a restricting member extending from the cap.
Abstract:
A control module may be used for raising and lowering a window shade. This configuration allows a user to pull the operating cord a predetermined distance to raise the window shade, then release the operating cord until it has retracted, and then pull the operating cord another predetermined distance to raise the window shade again. A brake mechanism is operably connected to a brake release and configured to lock or unlock the drive axle. A clutch is adapted to be mounted on the axle for selectively engaging the cord drum to the axle. The cord drum may rotate independent of the drive axle when a clutch is disengaged from the drive axle. As a result, movement of the operating cord will not cause the window shade to raise while the clutch is disengaged. When the clutch is engaged with the drive axle, the cord drum and adapter sleeve may rotate together to drive the rotation of the drive axle for raising the window shade.
