Abstract
Abstract An attachment for a television receiver composed of four trapezoidal panels adapted to be attached to the viewing screen of the television set and having reflective or mirrored inner surfaces whereby the image on the television receiver screen is reflected from the reflective surfaces of the four-paneled attachment. Each of the four trapezoidal panels are dimensioned so that when the attachment is mounted on the television receiver, the inner mirrored surfaces of each of the panels will define an included angle with the television screen which is between 100° and 120°.

Claim 1
Independent Claim
241 words
An image enhancing attachment for a television receiver having a viewing screen with a generally planar configuration comprising: four reflective panels each shaped in the form of a trapezoid with a front edge and a rear edge parallel to each other, said front edge being longer than said rear edge, and with a pair of side edges extending between each of said front and rear edges; hinge means attaching each of said reflective panels to two adjacent panels along said side edges thereof, said panels being attached so that in their assembled condition said front edges and said rear edges lie in respective common planes with said front edges and said rear edges arranged to form respective quadrilaterals; means for releasably attaching said assembled panels to said television receiver with said rear edges lying at least in the immediate vicinity of the plane of said viewing screen and in general conformity with the outline thereof; said assembled panels being arranged to have inner sides facing inwardly toward said viewing screen; and reflective surface means extending entirely over each of said inner sides of each of said four panels each reflecting a clear image of said viewing screen; said four reflective panels each being dimensioned such that when mounted on a television receiver in said assembled condition an included angle between the plane of said viewing screen and said inner sides of each of said four panels is between 100° and 120°.
