Abstract
An operating device for a rolling shutter assembly comprising a reeling shaft for a shutter wherein the shaft is rotated by a motor connected to a flange. The flange is fixed to a toothed wheel that can mesh with a thread of a screw so as to immobilize the rotation of the flange. The thread of the screw is provided with at least one flat, so that the mechanical connection between the toothed wheel and the screw can be disengaged when a flat is positioned adjacent the toothed wheel. Disconnection of the screw from the wheel allows a rapid operation of the shutter for reasons of security or maintenance.
