Abstract
A control unit for single and double track blinds is provided and consists of a sprocket wheel having a hub rotatably carried in the center of a passageway within a housing. An operating handle extends into the hub that extends through a central aperture in a front cover plate on the housing. The operating handle can be turned to rotate the sprocket wheel, thus driving a bead chain through the passageway to operate louvers in the single and double track blinds.
