Abstract: A window blind includes a headrail and a covering structure provided below the headrail. The covering structure includes multiple slats, which can be turned, lifted, and lowered. A driving module is immovably provided in the headrail and includes a power unit. A modulation assembly includes an adjustment member which is drivable to drive an adjustment cord assembly, turning the slats. A block and tackle system is provided in the headrail, and includes a movable member, which is drivable by the power unit to optionally reciprocate in a longitudinal direction of the headrail. A lifting cord assembly is connected to the block and tackle system, and extends out of the headrail to be fixedly connected to a bottom of the covering structure. When the movable member reciprocates in the longitudinal direction, the lifting cord assembly is driven to lift or lower the covering structure.

Abstract: A position-fixing system for a window covering, which has a roller tube, includes a variable diameter screw, a guiding portion, and an elastic member. The variable diameter screw has a working section gradually broadening in a radial direction thereof. The guiding portion extends along an inner wall of the roller tube in an axial direction thereof. The elastic member fits around the variable diameter screw, and is movable along the guiding portion. The elastic member has a meshing portion provided on an inner side thereof to mesh with the working section, and a guided portion provided on an outer side thereof to slide along the guiding portion. When the roller tube rotates in a direction, the elastic member moves along the working section and deforms, whereby to exert a gradually increasing unit tightening force to the variable diameter screw in the radial direction, dampening its rotation.

Abstract: A support structure for a roller for a shade includes a bracket, a plug and a limit member. The bracket is adapted to fix on a fixing member, and includes a connecting hole. The plug has one end connected to a shaft tube of the shade, and the other end thereof is inserted into the connecting hole of the bracket. The limit member is connected to the end of the plug, which is provided for being inserted into the connecting hole of the bracket, whereby the limiting member restrains the plug from detaching from the bracket. By the limit member, the connection of the bracket and the plug could be strengthened, so as to prevent the shade from falling off, whereby to enhance the safety of the support structure for the shade in use.

Abstract: A window blind includes a first rail, a second rail, a plurality of slats, a modulation mechanism, and an adjustment unit. The modulation mechanism includes a modulation shaft which can drive two warps of the ladder tape to make a relative movement in a vertical direction, whereby to modulate the slats to turn. When the slats are turned from a first position to a second position, the adjustment unit moves a rear cord which is used to move the second rail, whereby to change a length of a segment of the rear cord between a bottom edge of the first rail and a top edge of the second rail. In this way, the second rail could be turned along with the slats which are driven by the modulation shaft, and the problem of light leakage could be improved.

Abstract: A position-fixing system includes a pole, a guiding member adjacent to the pole, and a movable member fitting around the pole. The pole is immovable relative to a window covering. The guiding member includes a principal axis parallel to an extension axis of the pole, and includes a retaining face substantially extending in the direction of the principal axis, but non-coplanar with it. The movable member corresponds to the retaining face. The movements of the movable member and the guiding member are related to that of a shaft of the window covering. When the window covering is being operated, the movable member is driven to rotate around the pole, and moves along the pole and the guiding member. Due to the retaining face, the movable member keeps contacting the pole to create a friction therebetween. Therefore, the position of a covering material of the window covering can be precisely fixed.

Abstract: A control structure for a window covering includes a base, a revolving wheel having an axial post, a restriction means including a bushing fitting around the axial post, a transmission member provided on a side of the bushing, and at least one pawl connected to the axial post. The revolving wheel is connected to the base. The restriction means has at least one cutting groove. The transmission member has at least one abutting portion on an inner wall thereof. The pawl is pivotable within a width of the cutting groove. When the revolving wheel is rotated forward, an end of the pawl passes through the cutting groove to mesh with the abutting portion. When the revolving wheel is rotated backward, the pawl disengages from the abutting portion, and the transmission member is rotatable relative to the revolving wheel. Whereby, it could prevent generating noise while operating the window covering.

Abstract: A locking mechanism is disclosed, which is installed in a movable rail of a window covering, and is passed through by a cord. The locking mechanism includes a locking unit and a pressing member, wherein the locking unit includes a stopping member which is movable between a first position and a second position. The stopping member is normally located at the first position to abut against the cord, which prevents the cord from moving relative to the locking mechanism, whereby to maintain the position of the movable rail. By pressing the pressing member, the stopping member is moved to the second position, where the stopping member no longer abuts against the cord. Therefore, when the movable rail is moved in a direction away from a fixed rail of the window covering, the cord can move relative to the locking mechanism. Whereby, the movable rail can be smoothly moved downward.

Abstract: A damping adjustment device for adjusting a damping force to a window covering system while the window covering system is expanding, wherein the damping adjustment device comprises a damping module comprising first and second damping units. The damping force is outputted by the damping module to the window covering system when the first and second damping units generate an interaction force in between by a relative motion therebetween. An adjusting module is connected to the damping module for operating with the damping module simultaneously, wherein the damping force from the damping module is adjusted by the adjusting module altering a relative position of the first damping unit and the second damping unit when the relative motion occurs therebetween. A window covering system comprises the damping adjustment device, wherein expansion speed of a covering material of the window covering system can be effectively controlled and adjusted by the damping adjustment device.

Abstract: A TDBU (top down, bottom up) window covering includes a first crossbeam and a second crossbeam below a fixture, wherein a slat assembly is connected between the first crossbeam and the second crossbeam. A first control structure is further provided in the first crossbeam, and a second control structure is provided in the second crossbeam. The first control structure moves the first crossbeam toward or away from the fixture, and the second control structure moves the second crossbeam toward or away from the first crossbeam. Whereby, the assembling and the maintenance of the window covering are more convenient and easier.
