摘要： A quickly-assembled electric sunshade curtain is provided, which comprising a curtain frame and a curtain body; an upper end of the curtain body is fixedly connected with the upper rail, and a lower end of the curtain body is connected with a movable cross beam, which slidably cooperates with the curtain frame along an opening and closing direction of the curtain body. A single output motor and a transmission rod are disposed inside the upper rail. The single output motor is in transmission cooperation with the transmission rod through a gear assembly. A belt assembly is disposed in the side rails respectively. The first end of the transmission rod is connected to the belt assembly at one side through a quick connector and the second end of the transmission rod is connected to the belt assembly at the other side. The disposal of the quick connector improves the assembly efficiency.

摘要： An actuating system for a window shade includes a transmission axle, a brake assembly and a clutch. The transmission axle is rotationally coupled to an axle adapter for rotation about a longitudinal axis. The brake assembly includes an arrester, a rotary element rotatable about the longitudinal axis, and a shift collar configured to couple and decouple the rotary element from the arrester, the shift collar switching from a decoupling position to a coupling position in response to a rotation of the rotary element in a first direction and from the coupling position to the decoupling position in response to a rotation of the rotary element in an opposite second direction. The clutch can couple and decouple the axle adapter from the rotary element, and has a clutch actuator rotatable about the longitudinal axis to switch the clutch between a clutch coupling state and a clutch decoupling state.

摘要： The present invention discloses a blind slat positioning device and a window blind thereof. The positioning device can fix the slat at any height at which the slat is pulled down. The positioning device includes a turning seat which is provided at least with an overbend element for a pull cord to wrap around. The overbend element includes at least a ridge, resulting an effect that the slat stops at the height at which the slat is pulled down, with the aid of gravity.

摘要： A skew adjustment method and apparatus for adjusting the skewed condition of a movable rail of a window covering in which the movable rail is supported by lift cords wrapped around spools. A drive train disconnecting mechanism is used to disconnect a first spool from a second spool, the first spool is rotated relative to the second spool, thereby changing the length of the first lift cord relative to the second lift cord until the movable rail is in the desired position; and then the first and second spools are reconnected so the first and second spools rotate together. An end cap may be used to enable multiple disassemblies and reassemblies of the end cap to access the skew adjustment mechanism. In one embodiment, there are two movable rails, and the lift cords for both movable rails extend through the same rout holes in the covering. Disconnecting the first spool from the second spool may activate a mechanism that prevents the second spool from rotating.

摘要： We disclose a cordless window covering that may raise, lower, and tilt a plurality of slats without the use of lift cords. The covering may include an external frame with two vertical sides and a headrail. The covering may also include a plurality of slats, each of which may be connected to an adjacent slat by at least one string on each side and the headrail. This may allow the slats to hang freely when lowered. It may also allow all the slats to tilt when only the top slat has been mechanically tilted by a drive belt. The bottom slat may include a bottom bearing connector which may interact with a drive belt such that it may be raised and lowered when the drive belt rotates. Each slat may be connected to a bearing and a bearing connector that may be slidably connected to a guide channel.

摘要： We disclose a cordless window blind that includes at least one electromagnet within each slat. The slats may be inserted into orifices within rotatable slat mounting members on a vertical guide rail assembly. The orifices may house electrical connections which connect the electromagnets to at least one battery. The electromagnets may have the same polarity such that the electromagnet of one slat attracts the electromagnet of an adjacent slat. The magnetic attraction may move one slat toward the other slat causing the slats to move vertically along the guide rail assembly and either raise or lower the blinds. Alternatively, electromagnets on only one of two longitudinal edges of the slats may be actuated and attract a metal member on an adjacent slat. The magnetic attraction may cause the slats to tilt and rotate within the slat mounting members thus closing the blinds.

摘要： A cord winding structure for cordless blind is assembled in a cordless blind. A cord winder includes an upper case and a lower case which are respectively arranged a plurality of columns and posts and combined with each other by bolts. At least one winding wheel for winding a bearing rope, a driving wheel, and a driven wheel arranged corresponding to the driving wheel are assembled to the columns. The driving wheel, the driven wheel, and the winding wheel are respectively formed a gear-like driving portion. The gear-like driving portions of the wheels are engaged with one another. The driving wheel has a gradient coil spring which has different curvatures to result in a front end with weaker elasticity and a rear end with stronger elasticity. The front end of the gradient coil spring is winded on the driven wheel to make the cordless blind correctly be operated.

摘要： A driving assembly for window blinds includes a mounting plate, a driving wheel and a spring leaf wheel that are rotationally mounted on the mounting plate. The driving wheel is connected with a drive rod of a winding mechanism of a window blind, a spring leaf is arranged between the driving wheel and the spring leaf wheel, one end of the spring leaf is connected with the driving wheel, another end of the spring leaf is connected with the spring leaf wheel, and the driving wheel is driven by the drive rod to cause the spring leaf to tighten or relax thereby winding around the driving wheel or the spring leaf wheel. The driving assembly has simple structure and convenient assembly, and reliably provides a power for driving the winding wheels and the pull rope.

摘要： A curtain blinds spring motor elasticity maintaining structure, which provides a spring motor structure that prevents unproductive deformation and loss of elastic stress in a sheet band of a coil spring. The structure primarily consists of a kidney shaped wheel face provided on the outer circumferential surface of a drive drum. A first wound layer, a second wound layer, and a third wound layer of the sheet band are pulled and wound onto the drive drum to form a pressure accumulating coil, thereby arranging an anticipated configuration of curved tight windings of each of the wound layers along the kidney shaped wheel face, which prevents changes in the cross-sectional curvature of the sheet band and loss in elastic stress thereof, and thus maintaining an appropriate elastic force.
