Claim 1
Independent Claim
300 words
Apparatus for mounting a fan or similar device adjacent a ceiling having joists supporting the ceiling, comprising: a support bar adapted to be carried by adjacent joists; an outlet box; mounting means carried by the support bar and being movable along the support bar for supporting the outlet box at any one of a plurality of locations along the length of the support bar, the mounting means comprising a mounting element having a hook portion adapted to be received about the support bar and having a threaded shank portion extending downwardly from the support bar when mounted to the support bar, the mounting element being movable along substantially the full length of the support bar to align with a hole in the ceiling within which the outlet box is fitted, the threaded shank portion of the mounting element extending toward the hole; and, means carried by the mounting means for locking the outlet box in a stable position at any one of a plurality of locations along the length of the support bar, the locking means comprising a double nut element having two threaded holes formed therein, the holes being spaced apart and having the longitudinal axes thereof disposed in parallel relation, the threaded shank portion of the mounting element being received within one of the holes, the locking means further comprising a threaded bolt received within the other hole, the bolt being positionable away from the mouth of the hook portion to allow the support bar to be received by the hook portion, the bolt being further positionable relative to the mouth of the hook portion and being rotatable relative to the double nut element to extend into contact with the support bar to lock the mounting element at a desired location along the length of the support bar.
