Abstract

A roller shutter actuation device with a rotating roller shutter axis for raising and lowering a roller shutter, the axis of the roller shutter being rotated by means of a wheel driven by a driving member, in particular a roller blind cord, characterized in that the axis (10) of the roller shutter is connected in a rotationally solid manner with a coupling member (12) that has a bush area (13) arranged coaxially to the wheel (14-, 16) and to an element of stationary brake (18), which can be rotated with respect to the wheel (14, 16) to a limited extent out of a position of mutual rest and against the force of a spring and that contains in the bush area (13) one or more radial holes (30) with radially displaceable locking members (20) in them, whose radial thickness is greater than the thickness of the wall of the bush area, because in addition the wheel (14, 16) presents a oo several radially protruding knobs (15) which apply to the coaxially central bush area (13), are aligned with the holes (30) in the mutual rest position between the wheel (14, 16) and the coupling (12) and drive the locking members (20) in the direction of the brake element (18), and because the brake element (18) has one or more radially protruding stop tabs (33) that are applied to the bushing area (13) and are provided with radial depressions (34) arranged between them that run in the peripheral direction and in which the locking members (20) driven by the control lugs (15) fit in the rest position mutual, while retaining the coupling member (12) against rotation, while the locking members (20), under a rotating load of the coupling member (12) or the wheel (14, 16) and after its release by means of the command appendices (15), are radially displaced in opposite directions out of the mutual rest position by the stop lugs (33), at the same time canceling the retention against rotation.
