Abstract: A lighting fixture adapted to be mounted between parallel ceiling support grids includes a series of latches at the corners. The latches are retracted responsive to movement of the fixture to a position above the support grids and are released automatically after the fixture is disposed above the grids to define grid engaging supports for the fixture.

Abstract: The present invention is directed to a fixture which is characterized by its ability readily to be lamped and relamped, notwithstanding the fixture is located at a position which is accessible only with difficulty. The fixture includes a socket which coacts with the terminals of a bulb of particular design to center the terminals and to enable electrical and mechanical contact to be effected by a simple inward movement of the bulb relative to the socket.

Abstract: A recessed ceiling mounted lighting fixture is disclosed, characterized in the incorporation of improved mounting means for effecting connection thereof to a ceiling tile support grid. The mounting means includes spring projected latches which may be readily released to a grid engaging position by the installer and which automatically hold the fixture in a predetermined heightwise relation to the ceiling.

Abstract: The present invention relates to a lighting fixture adapted to be mounted directly to the ceiling of a room or the like. A characterizing feature of the invention lies in the provision of a frame structure adapted to seat against the upper surface of the ceiling, the frame structure including means in the nature of clips which are shiftable radially into complementary guideways formed in the frame, the clips in the course of such outward radial movement including tangs which embed themselves in the ceiling structure proper to securely mount the fixture at a desired position in the ceiling.

Abstract: The present invention is directed to a moisture sealed and vandal-resistant lighting fixture and is characterized by novel means for securing a diffuser in tightly sealed engagement against a gasket on the housing of a lighting fixture, which means precludes the ingress of moisture and reduces the likelihood that the fixture may be vandalized. More particularly, the invention relates to a lighting fixture, preferably rectangular, wherein the diffuser component is pressed against the mouth portion of the housing component by a cam arrangement, access to the cam arrangement being provided through a wall of the housing via an inconspicuous aperture or apertures whereby only one who is familiar with the operating characteristics of the fixture would recognize how to release the cam arrangement and, hence, the diffuser.

Abstract: The present invention is directed to a universal ceiling lighting fixture and more particularly is directed to a lighting fixture adapted to be mounted above a ceiling made of gypsum board, acoustical tile or the like, the fixture being characterized by its ability to support reflectors of a variety of diameters. More particularly, the fixture includes novel mounting means which extend over the reflector receiving aperture, the mounting means being adjustable in accordance with the diameter of the reflector intended to be used with the fixture.

Abstract: The present invention relates to an attachment clamp adapted to be mounted to a ceiling, such as a dry wall or acoustical tile ceiling, for structurally supporting a lighting fixture to the ceiling. The attachment clamp, which is formed of an integral resilient metal blank and a threaded adjustment member includes a foot portion adapted to be braced against the upper surface of the ceiling and a locking finger adapted to underlie the ceiling in spaced parallel relation to the foot portion, the threaded adjustment member being operable variably to space the foot and finger to clamp a thickness of ceiling between the two noted components.

Abstract: The present invention is directed to a tap member for use with a multi-conductor electrical track, e.g. a track having four (4) conductors, namely, three live conduits and a neutral conduit, which tap member is adjustable to enable the same to be connected selectively to any one of the three circuits defined between the live conduits and the neutral conduit.

Abstract: The present invention is directed to a lighting fixture mount, and more particularly to a heat dissipating or distributing lighting fixture mount which minimizes the transfer of heat generated by an incandescent bulb or the like in the fixture to the junction box providing the electrical power therefor, and most particularly to the screws which fasten the fixture to the junction box and consequently are exposed within the box to possible contact with the insulation of wires within the box. By preventing overheating of the support screws, the possibility of damaging the insulation and creating a short circuit is minimized.

Abstract: A flexible connector is disclosed for electrically and mechanically connecting the ends of diverging light tracks, the connector being characterized by its ability to be deformed or bent in any of a series of directions normal to the axis thereof and to maintain itself in said bent or deformed condition.

Abstract: The present invention is directed to a light track device of the type which mechanically and electrically supports fixtures such as spotlights or the like at any selected position along the length thereof, the device being characterized by an improved attachment module facilitating the formation of electrical connections between the conduits in the light track and the mains conduits. The module incorporates clamps or connector fixtures within which the mains conduits may be placed, secure mechanical and electrical interlock between the mains conduits and the fixtures being effected by the exertion of a lateral force against the mains conduits.

Abstract: The present invention is directed to an improved recessed lighting fixture for flush mounting in a hung ceiling structure or the like. The fixture is characterized by its ability to be securely anchored in position, yet be readily removed from a position below the ceiling for the changing of bulbs, replacement of electrical connections, etc. The apparatus includes a frame permanently mounted above the ceiling, installation of the reflector and attached light source components being effected by simple vertical movement of the reflector assembly. Removal of the reflector assembly from the frame is accomplished by a relative rotation of the reflector and frame.
