Abstract
Abstract A sun reflector formed by a carrier of transparent sheet material and internal louvers for use in a window panel is disclosed. The louvers are inserted across the width of the carrier and on equally spaced centers along its length. The louvers are received by the carrier at an angle acute to the plane of the surface. The louvers are formed of individual segments, each of which is equidistantly spaced from adjacent louver segments with the outer segments being spaced from the sides of the sheet material. The louver segments are encased by the sheet material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A louvered screen comprising a carrier body formed of transparent sheet material whose upper and lower surfaces substantially are continuous and throughout equidistantly spaced apart; and a plurality of opaque louver means disposed in and supported substantially stationarily by said carrier body, each of said louver means formed from at least two separate segments of material each having a substantially planar rectangular outline and a major and minor axis, said segments being positioned in the carrier body in a spaced apart discontinuous manner along their major axis, the space between said segments having nothing to impede vision through the carrier body; said louver means being spaced from adjacent louver means along a second dimension of said carrier body which is normal to said first dimension, each of said louver means being disposed at an angle acute to a plane normal to the surface of said carrier body, and each louver means and having a thickness greater than the product of the length of the minor axis of said louver means times the cosine of the angle of disposition so that each said louver means is embedded within said carrier body.
Claim 2
Dependent Claim
190 words
A louvered screen comprising a carrier body formed of transparent sheet material whose upper and lower surfaces substantially are continuous and throughout equidistantly spaced apart; and a plurality of opaque louver means disposed in and supported substantially stationarily by said carrier body, each of said louver means formed from at least two separate segments of material each having a substantially planar rectangular outline and a major and minor axis, said segments being positioned in the carrier body in a spaced apart discontinuous manner along their major axis, the space between said segments having nothing to impede vision through the carrier body; said louver means being spaced from adjacent louver means along a second dimension of said carrier body which is normal to said first dimension, each of said louver means being disposed at an angle acute to a plane normal to the surface of said carrier body, and each louver means and having a thickness greater than the product of the length of the minor axis of said louver means times the cosine of the angle of disposition so that each said louver means is embedded within said carrier body.
Claim 3
Dependent Claim
19 words
The louvered screen of claim 1 wherein each of said louver means are equidistantly spaced along said second dimension.
Claim 4
Dependent Claim
23 words
The louvered screen of claim 1 wherein each segment of said louver means is substantially coextensive and equidistantly spaced across said first dimension.
Claim 5
Dependent Claim
210 words
A window comprising two transparent panels and louvered screen positioned between and bonded to said panels, said louvered screen comprising a carrier body formed of transparent sheet material whose upper and lower surfaces substantially are continuous and throughout equidistantly spaced apart; and a plurality of opaque louver means disposed in and supported substantially stationarily by said carrier body, each of said louver means formed from at least two separate segments of material each having a substantially planar rectangular outline and a major and minor axis, said segments being positioned in the carrier body in a spaced apart discontinuous manner along their major axis, the space between said segments having nothing to impede vision through the carrier body; said louver means being spaced from adjacent louver means along a second dimension of said carrier body which is normal to said first dimension, each of said louver means being disposed at an angle acute to a plane normal to the surface of said carrier body, and said sheet material of said carrier body being of a thickness greater than the product of the length of the minor axis of said louver means times the cosine of the angle of disposition so that each said louver means is embedded within said carrier body.
Claim 6
Dependent Claim
210 words
A window comprising two transparent panels and louvered screen positioned between and bonded to said panels, said louvered screen comprising a carrier body formed of transparent sheet material whose upper and lower surfaces substantially are continuous and throughout equidistantly spaced apart; and a plurality of opaque louver means disposed in and supported substantially stationarily by said carrier body, each of said louver means formed from at least two separate segments of material each having a substantially planar rectangular outline and a major and minor axis, said segments being positioned in the carrier body in a spaced apart discontinuous manner along their major axis, the space between said segments having nothing to impede vision through the carrier body; said louver means being spaced from adjacent louver means along a second dimension of said carrier body which is normal to said first dimension, each of said louver means being disposed at an angle acute to a plane normal to the surface of said carrier body, and said sheet material of said carrier body being of a thickness greater than the product of the length of the minor axis of said louver means times the cosine of the angle of disposition so that each said louver means is embedded within said carrier body.
Claim 7
Dependent Claim
18 words
The window of claim 4 wherein each of said louver means are equidistantly spaced along said second dimension.
Claim 8
Dependent Claim
22 words
The window of claim 4 wherein each segment of said louver means is substantially coextensive and equidistantly spaced across said first dimension.
