Abstract (en)
The cord winding system for a Venetian blind comprises an electric motor (2) and a reducer housed in a casing (1). The reducer output shafts (3,4) drive two winding drums (12,14) on which the cords (13,15) are wound. A stop for when the blind is unwound by a desired amount is constituted by a screw (6) mounted coaxially and rotating with the output shaft in a cylindrical cage (9). A floating nut (7) on the screw is prevented from rotating in the cage. Motor stoppage for the completely unwound position of the blind is ensured by the blind abutting against the casing. Stopping of the blind is caused by the abutment of the nut against a stop fixed to the cage. Adjustment of the bottom stopping point is made by unlocking the cage and its rotational drive. Rotational locking of the cage in the casing is constituted by a transverse gear screw (17) meshing with a cage helicoidal tooth (16).
