The present invention provides for retractable coverings for architectural openings utilizing a control system having a single operating element allowing a user to move a retractable covering between extended and retracted positions by imparting a repetitive motion to the operating element. The control system may include an input assembly, a transmission, and an output assembly cooperatively engaging to convert linear movement of the operating element into rotational movement of a head roller in the required direction to provide movement of the covering in the desired direction and distance. The input assembly may convert linear movement of the operating element into rotational movement imparted to the transmission. The input assembly may also engage the transmission to effect the direction of rotational output from the transmission. The transmission imparts rotational movement to the output assembly, which interfaces with the head roller to rotate the head roller and to provide a braking feature.
An input assembly for a control system adapted to selectively extend and retract a covering for an architectural opening, wherein the control system has a transmission configured to receive a rotational input in a first rotational direction and selectively provide a rotational output in the first rotational direction or in a second rotational direction, the input assembly comprising:
An input assembly for a control system adapted to selectively extend and retract a covering for an architectural opening, the input assembly comprising:
A method of selectively extending and retracting a covering for an architectural opening, the method comprising:
