ABSTRACT:
A device for automatically releasing the braking mechanism of roller blinds or shutters or the like which are selectively operated by a motor drivingly connected to the drum of the blind wherein a drive shaft for the drum is prevented from rotating by gripping a brake disk between two rotating plates. Releasing of the brake is automatically effected as soon as the motor is activated by magnetic attraction of a yoke, which includes one of the rotating plates, against a spring element. In the event of an electrical failure, the brake may be released manually by mechanically urging the yoke from the brake disk against the action of the spring element.
