ABSTRACT:
A venetian blind wherein the slats are moved up and down by means of cords or strips in response to rotation of a shaft in clockwise and anticlockwise directions. The shaft actuates a mechanism serving to turn the slats between open and closed positions and through intermediate positions in which the slats are partly open. The mechanism is caused to automatically maintain the slats in the open positions during upward movement of slats and in the intermediate positions when the slats move downwardly. The slats can turn between the open and closed positions when the venetian blind is fully extended. Yieldable detents are provided to releasably hold the slats in the open, closed or intermediate positions.
