Abstract: A window covering system comprises a headrail, a bottom rail, a covering material, a control unit, and a first rotating unit, wherein the first rotating unit is configured to be driven to rotate in a first direction when the bottom rail descends to expand the covering material; and a locking device coiled to the first rotating unit, wherein the locking device provides a restriction force to the first rotating unit to restrict the first rotating unit from rotating in the first direction, as well as to restrict the bottom rail from descending; and an actuating device configured to operate with the control unit simultaneously; when the control unit drives the actuating device to push the locking device in order to reduce the restriction force provided by the locking device to the first rotating unit, the bottom rail descends to drive the first rotating unit to rotate in the first direction.

Abstract: A window blind includes a fixed rail and a plurality of slats hang below the fixed rail through a ladder tape. The slats are controlled by an output adjustment mechanism to change between a first state and a second state. In addition, an output clutch mechanism is provided to collect or to expand the window blind. Said output adjustment mechanism and said output clutch mechanism are both controlled by an input mechanism. Whereby, it requires only one single control module to adjust shielding of the slat assembly composed of the slats, and to expand or collect the slat assembly.

Abstract: A window blind includes an input mechanism adapted to change a location of a bottom rail, an adjustment output mechanism adapted to be motivated when the bottom rail is located at a low position, whereby to tilt slats between two positions, and an output clutch mechanism, which is adapted to be driven by the input mechanism to move the bottom rail toward a high position, and is adapted to be driven by the input mechanism to move the bottom rail toward the low position when it is at the high position. A stroke delay mechanism is provided on a transmission path from the adjustment output mechanism to the output clutch mechanism, which is adapted to delay an affected time for transmission. Whereby, only one single control module is required to adjust the inclination angle of the slats and to collect and expand the covering material.

Abstract: A control device reduces an expansion speed of a covering material of a window covering system. The window covering system comprises the control device, the covering material and a weight member attached below the covering material to provide a weight force to the covering material. The control device comprises a driving module, a lifting module comprising a winding device configured to operate with the drive member and the covering material simultaneously, a damping module configured to operate with the winding device in only one direction for providing a damping force to the winding device selectively; wherein the damping force is provided to the winding device for reducing the expansion speed of the covering material when the winding device is rotated in the first direction; and wherein no damping force is provided to the winding device when the winding device is rotated in a second direction opposite to the first direction.
