Abstract (en)
A control unit for controlling a lift system in a covering for an architectural opening includes a drive assembly and a brake assembly. The drive assembly includes a spool about which a pull cord can be wrapped or unwrapped and a spring for biasing the spool in a direction to wrap the pull cord thereabout. A drive gear is operatively associated with the spool so that upon a pulling of the pull cord and unwrapping of the cord from the spool, the drive gear is shifted axially into engagement with a driven gear in the brake assembly. The driven gear under such circumstances rotates a driven shaft, which in turn rotates a lift shaft in the covering to raise the covering from an extended position to a retracted position.
