Abstract
Abstract An overhead sign having polyhedral sections tapered vertically in opposite directions, the lower section comprising downwardly converging translucent panels having picture transparencies backlighted by concentrated light from overhead fluorescent room lights while upwardly converging decorative opaque panels overhang the upper edges of the translucent panels to minimize front lighting and perceptively brighten the pictures viewed by customers as well as minimizing shadows on the display counters below the sign.

Claim 1
Independent Claim
262 words
An overhead sign for disposition in spaced apart relationship below and for illumination from an elongated horizontally disposed light source which is simultaneously employed to illuminate a space below said overhead sign, said overhead sign comprising: a translucent relatively resilient lower member comprising a pair of spaced apart side walls sloped inwardly and downwardly toward each other and a pair of spaced apart end walls; each wall comprising an inner light-receiving surface and an outer light-emitting surface and at least some of said walls comprising an outwardly extending flange near the top thereof; an opaque upper member to which said lower member is detachably connected and comprising a pair of spaced apart side walls and a pair of spaced apart end walls; each wall of said upper member comprising an inner surface, an outer surface, and a lower surface; a surface on at least some of said walls of said upper member having a groove releasably receiving the flange of the associated wall of said lower members to detachably connect said lower portion and said upper portion of said sign; said outer surface sloping inwardly and upwardly relative to its associated inner surface, and said lower surface extending transversely away from said light-emitting surface of the associated lower wall, whereby said upper member permits direct illumination of said light-receiving surface from said light source but prevents direct illumination of said light-emitting surface from said light source, and permits illumination of said space below said sign from said light source; and means on said sign for suspending said sign below said light source.
