ABSTRACT:
A rolling security shutter system is provided with improved structure for resolving security, alignment and tracking problems in rolling shutters employing an interconnected set of slats. Problems of insecure mounting and interfitting of housing assembly elements precisely enough that there is no misalignment or binding of the slats as the shutter is opened and closed are resolved inpart by integrally cast single element sideframes mounted by means of mounting bars interfitting into integrated guided slot brackets. The slats are guided into alignment with the tracks by means of frictionally inserted guides held by the sideplates. Connection of slats to the roller core by a flexible spring panel improves salt to track alignment and security against forced entry. Hood strengthening support structural mounts register housing members for better slot alignment and strength and ease of dismount. Improved spring clip slat reinforcement bar retainers assure slat rigidity and alignment. Security is improved with key controlled locking means encompassed in the lowermost slat to move two bars into registering apertures in both tracks.
