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.

[ What is claimed is:] [1.] An apparatus for disengaging a motor-driven overhead door for raising the door, comprising:a motor having a drive shaft;a rotatable partition support member;a spring shaft having an axial passage; andmeans for selectively coupling said partition support member to said drive shaft for rotation therewith;said selectively coupling means comprising an actuating member at least partially passing through said axial passage;wherein, said actuating member is adapted to move from a first position at which said partition support member is coupled to said drive shaft for rotation therewith, and a second position at which said partition support member is uncoupled from said drive shaft.
