Abstract

A penetration resistant door light adapted to withstand impact from flying debris as might occur in a hurricane or other high-wind condition. The door light includes inner and outer frame halves that support a panel assembly within an opening formed in a door. The panel assembly includes a sheet or layer of transparent impact resistant material such as a polycarbonate or laminated glass. The impact resistant sheet is structurally secured to at least screws extend through all of the inner frame half, the impact resistant sheet, and the outer frame half. In an alternative embodiment, a structural adhesive intersecures the impact resistant sheet and the outer frame half.

Claims

1. A door light comprising:

an inner frame half;

an outer frame half;

a sheet of transparent, impact resistant material disposed between said inner and said outer frame halves; and

fastener means for structurally intersecuring said inner frame half, said outer frame half, and said sheet of impact resistant material wherein said transparent sheet defines a plurality of mounting holes; and

wherein at least one of said inner frame half, said outer frame half, and said fastener means extends through said mounting holes to secure said transparent sheet between said inner and said outer frame halves.

2. The door light of claim 1 further comprising a second transparent sheet intersecured to said sheet of impact resistant material in a spaced insulating construction.

3. The door light of claim 1 wherein said impact resistant material comprises a polycarbonate sheet.

4. The door light of claim 2, further comprising a third transparent sheet intersecured to said sheet of impact resistant material in a spaced insulating construction opposite said second transparent sheet.

5. The door light of claim 1 wherein said fastener means includes a plurality of mounting screws, each of said mounting screws extending through one of said mounting holes.

6. A window comprising:

an outer frame half to be mounted within an opening formed in a supporting structure;

a transparent sheet of impact resistant material and defining a plurality of holes about is periphery;

an inner frame half to be mounted within the opening in the supporting structure; and

a plurality of fasteners intersecuring said inner and said outer frame halves, said fasteners passing through said holes in said transparent sheet to mechanically intersecure said transparent sheet to said inner and outer frame halves.

7. The window of claim 6 wherein said transparent sheet includes tabs each defining one of said holes.

8. The window of claim 6 wherein said impact resistant material comprises a polycarbonate sheet.

9. A door, comprising:

a main body having front and back major surfaces, said main body further including an opening extending therethrough;

an outer frame half positioned within said opening;

an inner frame half positioned within said opening;

a first glass panel positioned within said opening between said inner and said outer frame halves;

a second glass panel positioned within said opening between said first glass panel and said inner frame half;

a polycarbonate sheet positioned within said opening between said first and said second glass panels, said polycarbonate sheet defining a plurality of mounting holes; and

fastener means extending through said mounting holes for intersecuring said inner frame half and said outer frame half such that said outer frame half and said inner frame half sandwich said main body, said glass panels, and said polycarbonate sheet, said inner frame half and said outer frame half directly engaging said polycarbonate sheet.

10. The door of claim 9 wherein said polycarbonate sheet is substantially coextensive with said first and second glass panels, said polycarbonate sheet including tabs protruding beyond the extent of said first and said second glass panels, said tabs defining said mounting holes and being directly compressed between said inner and said outer frame halves.

11. The door of claim 11 wherein;

said fastener means includes a plurality of screws, each of said screws extending through one of said mounting holes in said tabs whereby said polycarbonate sheet is directly secured to said inner and said outer frame halves.
