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 spring shaft to which a torsion spring is mounted. When the cable is pulled, the coupling mechanism is separated from the motor drive shaft, thereby disengaging the spring shaft from the motor drive shaft and permitting the torsion spring to quickly raise the rolling shutter.
