  • Patent number: 4706726
    Abstract: For the purpose of giving the user of an electric control of a venetian blind in a window the possibility of adjusting the angular position of the slats independently of raising or lowering the venetian blind by utilizing an electric motor, spring clutches, and corresponding lift cords, the electric control includes a control circuit with a three position switch controlled by the user. The control circuit is arranged so as to drive the motor at a low speed during a first predetermined time interval for adjusting the angle of the slats and thereafter to drive the motor at an increased speed for raising or lowering the venetian blind.
