ABSTRACT:
This invention relates to a strong, light weight accordion shutter system that increases strength while decreasing weight, and is especially resistant to hurricane force winds and flying objects when used to cover doors, windows or openings. More specifically, this invention relates to a shutter system comprising a plurality of connectable subsystems of shutters that are connected via a shutter mating system which provides sufficient strength to obviate the need to drill locking holes during installation and connection. This accordion shutter system also offers a unique ability to secure doors, windows and openings of any size from forced entry and enables the user to operate from either side of the shutter system. This invention further provides a unique and improved elongated header and extruded sill which come into contact with and provide greater support to the shutter blade while reducing load upon the guide pin.
