Abstract
Motorized device (2) for rolling up cords or tapes (13, 15) of Venetian or folded blinds, equipped with an automatic stopping device detecting a blockage of the motor. This automatic stopping device consists of a screw (6) carrying a traveling nut (7) rotationally retained in a tubular housing (9). Stoppage of the motor is caused by the detection of a blockage of the motor by the travelling nut (7) rotationally retained in a tubular housing (9). Stoppage of the motor is caused by the detection of a blockage of the motor by the travelling nut (7), or the blind, coming up against the casing. The bottom stopping point is adjusted by unblocking the cage (9) and rotationally driving it.
