ABSTRACT:
An accordion storm shutter assembly includes a frame for installation in an opening in a building wall and at least one folding shutter supported by the frame. The shutter is made up of plural blades articulated along their vertical edges so that the shutter can fold from a closed position in which the blades made a substantial angle--about 75.degree.--with one another so as to have a corrugated configuration blocking the opening, to an open position in which the blades are substantially parallel to one another. Neighboring blades are interconnected by continuous, extruded linear hinges, each having a socket which is substantially an arc of each cylindrical shell having a vertical axis. A knuckle formed along one edge of a neighboring blade pivots in the socket.
