A cordless retractable shade including an operating system for the shade that varies a biasing force of a spring to counterbalance the shade. The bottom rail of a retractable shade can be raised or lowered, and due to the operating system remains in any selected position of the covering between fully extended and fully retracted, without the use of operating cords. The system includes a method of negating and reversing the spring bias effect at a strategic position whereby the flexible vanes of the shade can be adjusted between open and closed.

An electromechanical actuator for driving a movable closure or sun protection screen includes a motor, a control board, a gear reduction assembly and a connector for connecting to a power supply source. The connector includes eight electrical contacts, the connector being in particular an RJ45 connector, for supplying power to the actuator and transmitting data from an Ethernet network. The motor is a synchronous motor including a wound stator and a rotor with permanent magnets, the stator winding being designed to withstand a voltage of 46V to 57V, in particular a voltage of 48V.

A roller shade actuation device includes two actuators arranged in a winding drum, a shaft inserted into the winding drum, and a transmission mechanism. Each actuator includes a housing fixed to the winding drum, a rotary power member arranged in the housing, a driving gear fixed to an output shaft of the rotary power member and coaxial with the output shaft, and a first transmission gear rotatably mounted to the housing and meshed with the driving gear. The actuators are connected linearly in sequence. The driving gear of one actuator adjacent to the transmission mechanism is transmission-matched with and connected to the transmission mechanism, and the driving gears of the remaining actuators are meshed with the first transmission gears of neighboring actuators adjacent to the transmission mechanism. The actuators are connected in series to form an actuator combination through the driving gears and the first transmission gears.

Disclosed are a roller blind balance regulator and a roller blind composed thereof. The roller blind balance regulator includes a stepped shaft and a friction cylinder, where the stepped shaft is provided with an external thread, the stepped shaft penetrates the friction cylinder, the friction cylinder is provided with an internal thread and is in threaded connection with the stepped shaft, and a friction layer is arranged between the friction cylinder and the stepped shaft. The roller blind includes a roller blind rod, a blind fabric, two mounting members, and the roller blind balance regulator, and a return spring is arranged in the roller blind rod. In the present invention, the roller blind rod drives the friction cylinder to rotate, so that the friction cylinder axially moves along a limiting screw while rotating, thereby increasing or decreasing a friction force between the friction cylinder and the friction layer.
