Abstract: A motorized venetian blind includes a first lifting electric machine, a second lifting electric machine and a tilting electric machine for respectively control a front pull cord, a rear pull cord and a ladder cord. When a front warp and a rear warp of the ladder cord are controlled by the tilting electric machine to move downwardly and upwardly respectively to tilt the slats to the closed position, one of the pull cords on the same side as the upwardly-moving warp is controlled by the first lifting electric machine or the second lifting electric machine to move upwardly along with the upwardly-moving warp. Therefore, the synchronization of the pull cords and the ladder cord is improved, whereby closure between the slats is enhanced, and the bottom rail can be fully tilted to be mostly vertical, partially overlapping the neighboring slat for preventing light leakage.

Abstract: A motorized window treatment has a headrail, a first operable rail and a second operable rail, a driving device, a distance detection circuit, a receiving circuit and a motor control circuit. The motor control circuit is coupled with the receiving circuit and the distance detection circuit for configuring the driving device to move the first operable rail and the second operable rail according to the signals received by the receiving circuit. When the receiving circuit receives a command signal to move the second operable rail towards a target position and the first operable rail locates between the second operable rail and the target position, the motor control circuit configures the driving device to move the second operable rail and the first operable rail collectively towards the target position.

Abstract: A top-down bottom-up window covering has a headrail, a middle rail, a bottom rail, a lifting control structure installed at the headrail, and a covering structure installed between the middle rail and the bottom rail. The lifting control structure controls a first rotating shaft and a second rotating shaft to respectively receive or release a first cord and a second cord. The first cord drives the middle rail to move, and the second cord drives the bottom rail to move. A one-way clutch and a pre-stress unit are further provided at the headrail. When the bottom rail pushes the middle rail to move upward, the one-way clutch breaks a link between the first rotating shaft and the lifting control structure. Consequently, a driving force generated by the pre-stress unit immediately drives the first rotating shaft to receive the first cord to keep the first cord taut.

Abstract: A window blind includes a housing, a slat assembly, a slat angle adjusting device, and a first cord. The slat assembly is provided below the housing, and has multiple slats and a bottom end portion. The slat angle adjusting device includes a rotating shaft assembly provided in the housing, and a ladder assembly which includes at least two ladders connected to the rotating shaft assembly for turning the slats. The first cord passes on a front or a rear side of the slats, and connects the rotating shaft assembly and the bottom end portion. Throughout the duration of the rotation of the rotating shaft assembly, the first cord and a warp, which belongs to the ladder assembly and on the same side as the first cord, are both reeled into or out of the housing concurrently, and the slats and the bottom end portion are all rotated concurrently as well.

Abstract: A vertical blind has a headrail, a transmission shaft, a plurality of slats located below the headrail with a gap, a driving assembly, a first clutch, a first pushing component, and a light-blocking member configured to be driven by the first pushing component to move from a blocking position coving the gap to a non-blocking position revealing at least a part of the gap. When the transmission shaft is driven to rotate in a first direction, the first pushing component is moved toward the first end of a movable region. When the first pushing component has been moved to the first end of the movable region and the transmission shaft keeps being driven to rotate in the first direction, the first clutch prevents the transmission shaft from further driving the first pushing component, whereby the first pushing component stays at substantially the first end of the movable region.

Abstract: A window blind includes a headrail, a covering assembly including a plurality of slats and a bottom rail, a lifting mechanism including a driving module and a lift cord assembly operably connected to the driving module, a tilt mechanism adapted to drive the slats to rotate, and an auxiliary unit provided between the tilt mechanism and the lifting mechanism. The lift cord assembly is connected to the bottom rail for expanding or folding the covering assembly. The covering assembly is in a first state when each and every one of the slats is substantially parallel to each other and correspondingly rotatable by the tilt mechanism, and is in a second state otherwise. When the covering assembly is in the second state, the auxiliary unit is drivable by the tilt mechanism to make the lifting mechanism further release the lift cord assembly, changing the covering assembly into the first state again.

Abstract: An electric window covering has a covering material, a driving device, a microcontroller, a position detecting module and a trigger detecting module. The position detecting module detects a position of a lower end of the covering material to generate a position information. The microcontroller compares the position information with a reference position to generate a position relationship with respect to the reference position. The trigger detecting module detects whether the covering material is moved by an external force for generating a detecting result. When the microcontroller determines that a trigger event is received according to the detecting result, the microcontroller configures the driving device to move the covering material according to the position relationship and the trigger event.

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.
