  • Safety release clutch for rolling shutters
    Patent number: 6244325
    Abstract: The present invention is directed to a modular roll-up partition assembly, such as a rolling protective shutter, implementing an improved mechanism for raising the partition in an emergency by disengaging a motor from a rolling shutter. The mechanism includes a cable that passes through an axial passage in a torsion spring. When the cable is pulled, the coupling mechanism is separated from the motor drive shaft, thereby disengaging the motor drive shaft from the shutter support member and permitting the torsion spring to quickly raise the rolling shutter.
