Abstract
Abstract A heat resisting canopy which utilizes a mosaic overlay of quartz or heat resisting glass elements adhesively bonded to a transparent organic shell. A transparent adhesive bonds each mosaic element to the organic canopy shell. A plurality of metallic ribbons, egg-crated together to form a lattice, stabilizes the mosaic structure, and individual elements are retained by a metallic wire mesh which covers the mosaic layer and which is attached to the canopy shell.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
A heat resisting canopy, comprising: a transparent shell made from an organic material, and defining a convex outer surface and a concave inner surface; a plurality of transparent elements made from an inorganic material and arranged upon said convex outer surface in the form of a transparent element mosaic outer layer; a transparent adhesive material joining each of said transparent elements to said transparent shell; a plurality of metallic ribbons arranged on said transparent shell convex outer surface to form a metallic ribbon lattice, wherein each of said transparent elements is bounded by a portion of said metallic ribbon lattice; and a plurality of metallic wires arranged over said transparent element mosaic outer layer to form a grid, wherein said grid defines a central intersection on each of said transparent elements, each metallic wire of said plurality of metallic wires having two ends, and each end of each wire being attached to said canopy.
Claim 2
Dependent Claim
154 words
A heat resisting canopy, comprising: a transparent shell made from an organic material, and defining a convex outer surface and a concave inner surface; a plurality of transparent elements made from an inorganic material and arranged upon said convex outer surface in the form of a transparent element mosaic outer layer; a transparent adhesive material joining each of said transparent elements to said transparent shell; a plurality of metallic ribbons arranged on said transparent shell convex outer surface to form a metallic ribbon lattice, wherein each of said transparent elements is bounded by a portion of said metallic ribbon lattice; and a plurality of metallic wires arranged over said transparent element mosaic outer layer to form a grid, wherein said grid defines a central intersection on each of said transparent elements, each metallic wire of said plurality of metallic wires having two ends, and each end of each wire being attached to said canopy.
