Douglas R Domel, Winston G Walker: Head rail-mounted mini-blind actuator. Harmonic Design, John L Rogitz, February 21, 1995: US05391967 (52 worldwide citation)

A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. Alternatively, the rotor is coupled to the tilt rod of the blind ...
