Abstract: An hanger unit for linear lighting fixture modules includes a housing with at least one, and typically two or a multiple of fixture connection ports, from which a linear fixture having a standardized male end connector can be releasably engaged by means of a quick release operation. Each fixture port of the hanger unit is provided with a circumferential flange structure which is, in part, formed by a bottom hinge bracket adapted to pivot downwardly to receive the fixture's corresponding male end connector and to releasibly lock over the male end connector when closed. A removable bottom cover piece covers the bottom hinge brackets and provides a completed hanger structure housing that compliments the appearance of the connected fixture modules. By using a number of hanger units made in accordance with the invention an articulated lighting fixture array can easily be installed and later modified or added to by adding or substracting fixtures to the connection ports of the hanger units.

Abstract: An adjustable overhead lighting fixture having fixed elongated support runners, which themselves may or may not be lighting fixtures, and a plurality of elongated hanger fixture elements which endwise releasably engage and span any two support runners at any point along the length of the runners and which are electrified from the runners. Hanger fixture elements may be used to support and electrify other hanger fixture elements such that the fixtures can be arrayed overhead to meet a variety of lighting applications.
