Abstract: A hanger assembly for attachment to a construction member or other commerically available ceiling fan support. The hanger assembly has an electrical box and a pair of support rods. The electrical box is a standard electrical box which has been modified by adding a pair of holes in the back thereof, each of the holes being in axial alignment with the respective threaded hole of the corresponding electrical box ear. Each of the support rods has a first threaded end section, a second threaded end section, a smooth section adjacent to the first threaded end section and a spline section intermediate the second threaded end section and the smooth section. The respective support rod is secured to the back of the electrical box after the first threaded end section is inserted into the corresponding back hole. The spline section of the respective support rod is in frictional engagement with the corresponding threaded ear hole.

Abstract: A hanger assembly for one-handed mounting between opposing surfaces of wall studs or ceiling joists in normally inaccessible places. The hanger assembly has telescoping elements with toothed ends which are adapted to pierce into wall studs or ceiling joints when the elements are extended. The telescoping elements are spread apart by planting starter teeth on the follower element into a stud or joist and then turning a main body element until the end teeth of the follower element and the end teeth of the main body unit are fully embedded. The follower element is preferably spring loaded so as to provide the hanger assembly with a following or self-adjusting action. The self-adjusting action causes the hanger assembly to adapt to deformations of the wall studs or ceiling joists and to retain the compressive attachment integrity of the hanger assembly.

Abstract: A hanger assembly for one-handed mounting between opposing surfaces of wall studs or ceiling joists in normally inaccessible places. The hanger assembly has telescoping elements with a pilot screw and load bearing teeth on each end. Each end is independently installed. The pilot screw is used to pull in and attach the load bearing teeth on the respective end into a wooden joist or stud. The installation is thus accomplished without requiring or experiencing installation jackscrew forces which would disturb the joist and ceiling boards causing ceiling board nail displacement.
