Claim 1
Independent Claim
317 words
A cornice lighting fixture for mass transit vehicles, said fixture comprising: an elongated sheet-like unitary molded body including a lamp panel defining one longitudinal margin of the fixture and a trim panel extending obliquely in a downward and outward direction from a corner-like juncture of one edge thereof with one edge of the lamp panel and defining the other longitudinal margin of the fixture, said trim panel including a mounting flange extending along the other edge thereof, said lamp panel including a vertical portion extending upwardly from said one edge thereof and including a horizontal portion extending inwardly from the vertical portion and terminating in a free edge, said lamp panel opening inwardly and downwardly and adapted to receive a fluorescent tube, an extruded connector extending along said free edge and attached thereto, said connector having a horizontal portion overlapping said horizontal portion of the lamp panel to provide a double-wall mounting strip for connecting the fixture to the vehicle, said connector having a groove therein extending along said free edge and opening downwardly, an elongated lens cooperating with said lamp panel to enclose said fluorescent tube and having an upper edge interlocked in said groove and having a lower edge terminating adjacent said corner-like juncture and secured to said one edge of said trim panel outwardly of said corner-like juncture by a removable fastener, first and second extruded retainer strips secured to said trim panels and extending longitudinally thereof in parallel spaced relation, each of said retainer strips having an overhanging lip extended along one edge thereof and spaced from the surface of said trim panel to define a retaining groove which opens toward the other retainer strip, said retaining grooves being adapted to receive the edges of an advertising card to retain it on said trim panel adjacent said lamp housing, said first retainer strip being disposed outwardly of said lower edge of said lens.
