A window blind includes a headrail, a controller, a rotating rod, a pivoting member, a blind body, a bottom rail, two lift cord sets, two tilt cord sets and two cord winding assemblies. With the technical feature that the rotating rod and the tilt members of the cord winding assemblies are arranged in the same axial direction in sequence, the effect of almost synchronous rotation can be achieved, thereby optimizing the complexity of the overall blind window components or related parts.

A screening device includes a rail, a drive shaft, a motorized drive device, including an electromechanical actuator, and an autonomous electrical power supply device, including a battery module. The battery module includes first and second mounting brackets, each arranged inside the rail and configured to hold the battery module inside the rail. The actuator includes third and fourth mounting brackets, each arranged inside the rail and configured to hold the actuator inside the rail. The brackets are identical. Furthermore, each of the brackets includes an opening, configured to accommodate the drive shaft.

In one aspect, a cordless covering may include a roller and a shade panel configured to be wound around and unwound from the roller to move the shade panel between an extended position and a retracted position. The shade panel may include a front panel, a back panel, and a plurality of vanes extending between the front and back panels. The covering may also include a roller shaft extending through the roller and a tilt adjustment mechanism coupled to the roller shaft. The tilt adjustment mechanism may be configured to rotate the roller shaft to adjust a tilt angle of the vanes between an opened position and a closed position.

An electromechanical actuator includes a housing, an electronic control unit and a switching device. The switching device includes a first member which is attached to a wall of the housing by removable attachment elements and arranged opposite an opening of the wall, and a second member which is movable relative to the first member. The electronic control unit includes a switch and a printed circuit board. The switch is actuated by the second member through the opening provided in the wall and is assembled on the printed circuit board. The printed circuit board includes an electrical connection device arranged opposite the opening of the wall. Moreover, the electrical connection device is accessible through the opening, after the first and second members are withdrawn from the wall, by removing the removable attachment elements.

Disclosed is a hollow louver top operating system comprising a rotating mechanism configured to open and close louver blades of a curtain; and a lifting mechanism configured to lift the curtain up and down, wherein the rotating mechanism comprises a rotating rope and a top rotating controller, and the rotating rope is connected between the top rotating controller and a first side of the curtain, wherein the lifting mechanism comprises a lifting rope and a top lifting controller, and the lifting rope is connected between the top lifting controller and a second side of the curtain, and wherein the top rotating controller and the top lifting controller are disposed in an upper frame portion of the window frame.

The present invention relates to a safety blind that operates without a cord. More specifically, there is no danger of safety accidents because a lifting cord inserted into a fabric tube of a leather cord is not exposed to the outside, the lifting and tilting operation of an entire slat can be easily and simply performed by operating a lower slat, and a driving unit can be applied to Venetian blinds, roll blinds, and various blinds.
