Abstract: A foldable shutter for protecting sliding glass doors from storms and break-ins is formed of vertical panels hinged together. The panels are extruded with full length beads on both sides and are held together by long extruded hinge clips having separate channels into which beads of adjacent panels fit. These hinge clips are substantially longer than the panels and the ends are closed by closure members having pins extending into the channel and spacing the panels from the ends. These closure members support the shutter on rollers in an upper guide and guide the bottom of the shutter in a lower guide. The hinges have three separate functions--to hold the panels together, to support the shutters, and to hold the shutters in place in the guides. Locking end trim sections for the shutter are hinged to the end panels and are also longer than the panels for support and guidance.

Abstract: A winding mechanism for rolling and unrolling an articulated shutter curtain, the winding mechanism comprising a tubular drum with a plurality of integral, spaced-apart arms protruding from its exterior surface. The shutter curtain is attached to one of the arms such that rotation of the tubular drum rolls up the curtain from an extended position or rolls down the curtain from a rolled-up position. More particularly, each arm is alternatively provided at one end with either a rod-like or socket-like projection extending along an edge thereof for slidable interconnection with the rod-like or socket-like projection extending along an edge of the top slat of the shutter curtain. In addition, each arm portion is provided with an arcuate land portion for supporting the shutter in a rolled-up fashion. The tubular drum from which the arms protrude is formed with two half cylindrical elongated members which are slidably engaged by longitudinal bent-over interlocking portions disposed along each edge of the members.
