Abstract:
1. A system for securing a window pane framed by a pair of opposing side frame members, a top frame member and a bottom frame member, the frame members being surrounded by a pair of side casings, a head casing and a window sill, the system consisting essentially of: an exterior polycarbonate cover including four corners and four through-holes wherein each of the four through-holes are each disposed diagonally inside one of the four corners, the cover including a pair of opposing side edges, a top edge and a bottom edge, the cover being sized so that the opposing side edges rest on the side frame members with two side gaps disposed between the side edges of the cover and the side casings, the two side gaps having a cumulative width of 0.5 inches or less; a first interior clamping beam and a second interior clamping beam, each of the clamping beams including two opposite ends and only two through-holes with a single through-hole disposed inside each of the opposite ends, the first and second clamping beams being elongated and flat, wherein each end of each clamping beam includes a foot for engaging an interior surface of a building structure and supporting the clamping beams above said interior surface; and four threaded fasteners and four nuts, each fastener having a head connected to a threaded shaft that passes through one of the four corners of the cover and one of the through-holes inside the opposite ends of one of the beams, each head directly engaging the cover, each nut threadably engaging one of the threaded shafts for imposing a clamping force between the cover and one of the clamping beams.
