ABSTRACT:
The present invention is directed to a roll-up partition comprising a rolling shutter, a shutter assembly, a flexible strap and a tensioner. The tensioner includes a locking mechanism that is configured to lock and unlock the flexible strap and a quick release mechanism configured to release the locking mechansim, thus allowing the rolling shutter to change positions. The invention also includes a strap recoiler with a locking mechanism and a quick release mechanism, wherein activation of the quick release mechanism causes the release of the locking mechanism, thus allowing the roll-up partition to change positions. The invention also includes a method of exiting an enclosed space partially bounded by a portal protected by a roller shutter. The method includes operating the quick release mechanism, waiting for the shutter to retract and exiting the space through the portal.
