High velocity category 5 accordion shutter system

摘要

An accordion shutter system has a folding arrangement of interconnected slats moveably supported on a track assembly. The track assembly includes an overhead header with longitudinal rails on opposite sides of a central gap and outboard abutment surfaces. The track assembly further includes a lower floor track extending parallel with the header along the same plane and having a guide slot arranged in opposing relation to the gap in the header. The slats extend vertically between the header and floor track and are each rotatable about a vertical axis defined at the interconnection of male end and female end fittings of adjacently positioned slats. Trolleys are captivated within the header and have opposite wheels for rolling travel along the rails. Each trolley connects to the center of a correspondingly positioned slat to support the slat vertically between the header and floor track and to permit evenly balanced horizontal and folding movement of the folding slat arrangement between a fully open position and a closed position to protectively cover a door, window or other building structure.
