Patent ID: 8100374

Claim:
A ceiling fixture to be affixed to and between two studs having a given distance between the studs, the ceiling fixture having a canister frame, comprising: a. a first hanger bar assembly attached to a side of the canister frame and a second hanger bar assembly attached at an opposite side of the canister frame, each hanger bar assembly comprising an elongated hanger bar having a longitudinal body including a longitudinal rib and elongated receiving member on its lengthwise upper and lower edge, and a mating elongated hanger bar having an elongated body including a longitudinal rib slidably retained within the receiving member of its mating hanger bar; b. the first hanger bar assembly having a multiplicity of spaced apart openings, the second hanger bar assembly having a multiplicity of spaced apart openings; c. each hanger bar assembly having a connecting member inserted into a respective pair of aligned openings in the first and second elongated hanger bars so that the connecting member restrains movement of the two hanger bars relative to each other; d. each hanger bar assembly having a first mounting bracket rotatably attached by a press fit rotatable member to a side of a rib of the elongated hanger bar, and having a bracket plate supporting an attaching member and a second mounting bracket fixedly attached to a side of a rib of the mating elongated hanger bar and having a bracket plate supporting an attaching member, the mounting brackets separated by a desired distance; and e. the two hanger bars of each hanger bar assembly slidably movable relative to each other so that the distance between the two mounting brackets on the hanger bar assembly is equal to the distance between the two studs and the position fixed by the connecting member with an excess length of each hanger bar cut off without removing the hanger bar from the hanger bar assembly, and the rotatable mounting bracket positioned so that they are opposite each other so that a nail located in each rotatable mounting bracket can be hammered into the stud while the ceiling fixture hangs downwardly from the stud and thereafter the mounting brackets are rotated by ninety degrees so that each nail in the opposite fixed mounting brackets can be nailed to the opposite stud.
