An actuation assembly for a continuous looped operator includes a slide assembly configured to laterally slide in a first direction and a second direction opposite the first direction, a first cord engagement member carried by the slide assembly, a second cord engagement member carried by the slide assembly, and a selector switch connected to the slide assembly, the selector switch receives a portion of the first cord engagement member and a portion of the second cord engagement member, the selector switch configured to move relative to the slide assembly between a first position and a second position.

The present disclosure concerns cable-covering tube assembly for a roller blind actuation cable, comprising a first cable-covering tube defining a cable-receiving cavity; and at least one tube connector extending at least partially in the cable-receiving cavity and comprising a cable-mounting portion couplable to the free end portion of the roller blind actuation cable; and a coupling portion couplable to the coupling portion of a similar tube connector. It also concerns a cable-covering tube system and a roller blind actuation assembly comprising first and second roller blind-operating systems having each a driving assembly and a unidirectional angular coupler, and a biasing member operatively coupling the driving assemblies and extending between their respective unidirectional angular couplers

A window blind, wherein each ladder tape thereof includes two longitudinal cords, plural bearers and plural limiting members. The longitudinal cords each have an end connected to a deflecting mechanism disposed on the upper rail. The bearers are disposed between the two longitudinal cords for respectively supporting the slats. The limiting members include a first limiting member and a second limiting member neighboring thereto. The first limiting member has an end disposed on one of the longitudinal cords and includes a first slat-through portion located between two ends thereof passing through a first through hole of a first slat. A first linking loop is formed after the first slat-through portion passes through the first through hole. The second limiting member passes through the first linking loop for keeping the first through hole threaded through by one of the first limiting member and the second limiting member.

The geared window shade bracket comprises a sprocket having a ring gear on an inside circumference of the sprocket; a chain configured to be engaged with the sprocket such that, in response to pulling on the chain, the sprocket rotates; a sun gear that is configured to be restricted from rotation; one or more planet gears configured to rotate around the sun gear, wherein the one or more planet gears interface with the ring gear; and a planetary carrier configured to mate with the one or more planet gears. In response to the chain being pulled, the sprocket rotates, causing the planet gears to rotate, causing the planetary carrier to rotate, causing the hub to rotate, and causing a shade tube to rotate.

A motor drive system for operating a mechanism for raising and lowering window coverings includes a motor operating under electrical power and an electrically powered drive system. The motor drive system advances a continuous cord loop in response to positional commands from a controller. An input-output device includes a capacitive touch strip that receives user inputs along an input axis, and an LEDs strip aligned with the input axis. A group mode module communicates the positional commands to other motor drive systems within an identified group to operate respective other mechanisms of the other motor drive systems. A set control module enables user calibration of a top position and a bottom position of travel of the window covering. The input-output device extends vertically on the exterior of a housing for the motor drive system, and the housing supports input buttons of the group mode module and the set control module.
