摘要

Having as essential elements: A drive shaft (1) attached to the rolling drum (23) of the blind (21), linked by means of a first free wheel mechanism (2) to an actuating cylinder (4) having a releasing sector (5). A lobed wheel (17) having projections (18) between which corresponding extensions (19) of the slats (20) of the blind (21) are housed, and which is linked through a second free wheel mechanism (15) and certain gear elements to a locking sector (26). A fixed braking cylinder (7), housing inside of it a braking spring (9), the ends of which make up as many stops (10) defining two sector housings intended for receiving the releasing sector (5) and the locking sector (26), the latter acting upon the stops (10) in the direction of increasing the apparent diameter of the braking spring (9), and the releasing sector in the direction of reducing the apparent diameter of the braking spring (9).
