International Classification:

E06B 104

US Classification:

52217

Abstract:

A metal subframe is anchored into an opening in a building wall as the wall is being built. A factory-glazed and factory-welded metal frame is snapped into the subframe conveniently from inside of the building. integral one-way clips or latches automatically align, center and permanently capture the frame as it is installed in the subframe, and no field welding is thus required. The latches are internal and inaccessible when locked, thereby making this metal window construction well suited for security installations.

US Classification:

109 215

Abstract:

The present invention is directed to a forced entry and ballistic resistant barrier comprising a plurality of adjacent segments securely and rigidly affixed to each other. Each segment includes a first pair of longitudinally elongated C-shaped channels whose concave sides are diametrically opposed about a flat bar positioned therebetween. In addition to the first pair of C-shaped channels, each segment preferably comprises a second pair of longitudinally elongated C-shaped channels, larger than the first pair, positioned concentrically about the first pair such that one channel of the second pair overlaps a convex portion of one channel of the first pair; the other channel of the second pair overlaps a complementary convex portion of the other channel of the first pair. The first and second pair of C-shaped channels are positioned so as to preferably obtain a relatively high Free Area percentage while still maintaining strict ballistic resistance and forced entry standards.
