Abstract: A control system for a shutter is disclosed. The shutter includes a force-bearing mechanism and a plurality of slats. The control system includes a power source, a driving device connected to the power source to output a first driving force, which drives the force-bearing mechanism to rotate the slats, and a clutch mechanism, which includes an input member and an output member which are drivable to be connected together for synchronous operation, or to be mutually disconnected for independent operation. When the driving device outputs the first driving force, the input member is engaged with the output member, and the first driving force can be transmitted to the force-bearing mechanism through the clutch mechanism to rotate the slats. When the driving device stops, the input member is disengaged from the output member, and the slats and the force-bearing mechanism are rotatable relative to the driving device.

Abstract: A charging system and a method of charging an electric window covering are disclosed. The electric window covering includes a power supply device and an electric power input, which is provided in a frame and coupled to the power supply device. The charging system includes a charging device, which includes an extension object, an electric power output, and a power storage device which stores a power. The electric power output and the power storage device are respectively connected to the extension object, which is erectable in a longitudinal direction thereof. When the charging device is connected to the frame and suspended therefrom, the power of the power storage device is transmitted to the electric power output through the extension object, and then provided to the electric power input, whereby to charge the power supply device. Therefore, the method can be easily performed with said charging system.

Abstract: A light blocking system is disclosed, which is adapted to be used in a vertical blind which includes a headrail, a control mechanism provided in the headrail, and a covering assembly including a plurality of slats. Each of the slats is connected to the control mechanism with an end thereof, and therefore is hung below the headrail. A gap is left between the covering assembly and the headrail. The control mechanism is adapted to turn the slats in situ relative to the headrail, or to move the slats back and forth in a longitudinal direction of the headrail. The light blocking system includes a cover plate provided corresponding to the gap, wherein the cover plate covers the gap when the covering assembly is in a closed state.

Abstract: A control module of a cordless window covering is disclosed, wherein a first prestressing device and a second prestressing device are provided on two lateral sides of a reel which is adapted to be wound around by lifting cords. In the condition that one single reel is wound around by two lifting cords, the number of gears linked to be rotated together could be reduced. In the condition that the control module is applied to a large window covering which has odd numbers of lifting cords, the pulling force provided by the first prestressing device and the second prestressing device could be distributed evenly on the reel, and the control module could effectively withstand the loadings of the lifting cords, which prevents the window covering from tilting, or prevents the problem that the springs are insufficient to bear the loadings.

Abstract: A separable tilting device includes a case, a first driving member, a second driving member, and a connector. The first driving member and the second driving member are provided in a chamber of the case, and are movable by each other. The connector is connected to the first driving member, wherein the connector has an engaging slot. An end of a stop member of the case extends into the engaging slot, so that the connector could not be disengaged from the first driving member. An end of the connector is controllable to rotate the first driving member. Whereby, the first driving member and the second driving member are completely hidden inside the case, which prevents the tilting device or slats of a window covering from being damaged.

Abstract: An adjustable cord locker for fastening at least a lift cord to a bottom rail and regulating a length of the lift cord includes a barrel, a reel, and a control wheel. The reel is received in the barrel for rotation by control. The lift cord is inserted into the barrel and fastened to the reel to be wound around the reel when the reel is turning. The control wheel is connected to the reel for a user to operate to turn the reel. The control wheel is provided with teeth, and the barrel is provided with a pawl. The pawl is engaged with the teeth to allow the control wheel to be turned or hold still.
