Abstract
An electrical raceway for installation in an illuminated double-sided sign box is in the form of an elongated and hollow structure which provides reinforcement for such a sign box and a housing for electrical conductors. Opening zones, usefully in the form of knock-out discs are provided in the side walls of the raceway for the mounting of lighting fixture receptacles while aligned openings in such side walls are provided for the disposition therethrough of an elongated lighting tube terminally fitted in receptacles on a pair of such raceways disposed on opposite sides thereof. Deformable tongues formed in such side walls at such openings can be bent toward the opposite side walls to provide barrier members to prevent the electrical conductors within such a raceway coming into contact with a lighting tube extending therethrough.
Claims16
An electrical raceway for incorporation in a double-sided sign box to provide structural reinforcement to such a sign box when incorporated therein so as to extend between spaced apart walls thereof, for the mounting of electrical receptacles for elongated lighting tubes and for housing electrical conductors connected to such receptacles for the supply of electricity thereto and which raceway comprises;
- an elongated and hollow structure adapted to be disposed within such a sign box between such spaced apart walls thereof with such electrical conductors disposed therewithin and having mutually spaced apart side walls;
- electrical receptacle opening zones formed in said side walls adapted to have electrical lighting fixture receptacles secured therein for the terminal engagement of elongated electrical lighting tubes;
- lighting tube openings in said side walls, spaced longitudinally apart from said opening zones along said side walls, said openings being formed in aligned pairs for the free disposition therethrough of other such elongated electrical lighting tubes whereby such a tube may pass completely through such raceway without contacting the same, and,
- at least one retaining member adapted to project between said side walls of said raceway adjacent such pairs of openings to retain electrical conductors in position within said raceway transversely outwardly of such lighting tubes extending through said aligned openings.
