Abstract
Abstract There is disclosed a television viewing apparatus especially adapted to provide an illusion to the user of three-dimensional images comprising: a housing having a first aperture adapted for alignment with the eyes of the user and a second aperture adapted for alignment with a television screen; a convex arcuate segment of transparent material substantially adjacent to the first aperture; a first concave arcuate segment of transparent material substantially adjacent to the second aperture; and a second concave arcuate segment of transparent material and intermediate to the convex arcuate segment of transparent material and to the first concave arcuate segment of transparent material cooperate to deflect the image received from the television screen and provide an illusion of three-dimensional images to the user.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
156 words
A television viewing apparatus comprising: a housing means having a first aperture adapted for alignment with the eyes of the user and a second aperture adapted for alignment with a television screen; a first lens means positioned within said housing means and substantially adjacent to said first aperture wherein said first lens means includes a convex arcuate segment of transparent material said convexity being relative to said first aperture; a second lens means positioned within said housing means and substantially adjacent to said second aperture wherein said second lens means includes a first concave arcuate segment of transparent material said concavity being relative to said first aperture; and a third lens means intermediate to said first and second lens means wherein said third lens means includes a second concave arcuate segment of transparent material and a main chord, wherein said main chord of said third lens is parallel to a plane formed by said first aperture.
Claim 2
Dependent Claim
156 words
A television viewing apparatus comprising: a housing means having a first aperture adapted for alignment with the eyes of the user and a second aperture adapted for alignment with a television screen; a first lens means positioned within said housing means and substantially adjacent to said first aperture wherein said first lens means includes a convex arcuate segment of transparent material said convexity being relative to said first aperture; a second lens means positioned within said housing means and substantially adjacent to said second aperture wherein said second lens means includes a first concave arcuate segment of transparent material said concavity being relative to said first aperture; and a third lens means intermediate to said first and second lens means wherein said third lens means includes a second concave arcuate segment of transparent material and a main chord, wherein said main chord of said third lens is parallel to a plane formed by said first aperture.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1 wherein the radius of curvature of said convex arcuate segment is substantially equal to the radius of curvature of said first concave arcuate segment.
Claim 4
Dependent Claim
26 words
The apparatus of claim 2 wherein each end of said second concave arcuate segment is adjacent to the inner surface of said first conVex arcuate segment.
Claim 5
Dependent Claim
52 words
The apparatus of claim 3 further comprising a first guide means connected to said housing means to position said first lens means a preselected distance from said first aperture and a second guide means connected to said housing means to position said second lens means a preselected distance from said second aperture.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4 further comprising a third guide means connected to said housing means to position said third lens means adjacent to said first lens means.
Claim 7
Dependent Claim
31 words
The apparatus of claim 5 further comprising a fourth guide means connected to said housing means to effectuate the alignment of said television viewing apparatus with the eyes of said user.
Claim 8
Dependent Claim
33 words
The apparatus of claim 6 wherein said housing means comprises a hollow box like structure wherein said first aperture and said second aperture are spaced at opposite ends of said box like structure.
Claim 9
Dependent Claim
37 words
The apparatus of claim 7 wherein said first lens means and said second lens means are connected thereby forming a substantially cylindrical element having a radius equal to the radius of curvature of said convex arcuate segment.
Claim 10
Dependent Claim
94 words
A television viewing apparatus comprising: a housing means having a first aperture adapted for alignment with the eyes of the user and a second aperture adapted for alignment with a television screen; a transparent cylindrical element positioned within said housing whereby the longitudinal axis of said cylindrical element is substantially parallel to a plane formed by said first aperture; and a concave arcuate segment of transparent material including a main chord positioned within said cylindrical element wherein said main chord of said arcuate segment is parallel to said plane formed by said first aperture.
Claim 11
Dependent Claim
94 words
A television viewing apparatus comprising: a housing means having a first aperture adapted for alignment with the eyes of the user and a second aperture adapted for alignment with a television screen; a transparent cylindrical element positioned within said housing whereby the longitudinal axis of said cylindrical element is substantially parallel to a plane formed by said first aperture; and a concave arcuate segment of transparent material including a main chord positioned within said cylindrical element wherein said main chord of said arcuate segment is parallel to said plane formed by said first aperture.
Claim 12
Dependent Claim
55 words
The apparatus of claim 9 further comprising a first guide means connected to said housing means to position each of the ends of said arcuate segment adjacent to the inner surface of said cylindrical element and whereby the ends of said arcuate segment form a plane parallel to said plane formed by said first aperture.
Claim 13
Dependent Claim
50 words
The apparatus of claim 10 wherein said housing means comprises: a first pair of parallel walls; a second pair of parallel walls each connected to said first pair of parallel walls wherein said first and said second pair of parallel walls cooperate to form said first and said second apertures.
