Universal luminaire mount

A mounting apparatus for attaching luminaires to a support member of a building structure and connecting such luminaires with a source of electricity comprising:

• a central housing member including a top member having an elongated slot centrally located therein and first and second mounting slots positioned on opposed sides of said central elongated slot, a mounting plate adapted to slideably engage said top member of said central housing having a threaded aperture located to communicate with said central elongated slot when said mounting plate is engaged with said top member of said central housing, means to attach said central housing to such a support member positioned in said threaded aperture, and a terminal for receiving electrical wires from such source of electricity;
• a ballast housing interconnected with said central housing and detachable therefrom;
• a fuse housing having at least one fuse member interconnected with said central housing and detachable therefrom, said fuse housing being in communication with said terminal of said central housing and said ballast housing whereby said fuse housing receives electricity from said terminal and directs such electricity to said ballast housing;
• a means for interconnecting said fuse housing and said ballast housing with said central housing including a resilient two-step retaining clip fixed to said ballast housing, said retaining clip having a first tab member adapted to engage said central housing and interconnect said ballast housing with said central housing and a second tab member adapted to engage said fuse housing and interlock said fuse housing with said ballast housing when said fuse housing is interconnected with said central housing, whereby said fuse housing must be disengaged from said second tab member and removed from interconnection with said central housing before said ballast housing and said first tab member are disengaged from said central housing.

A mounting apparatus for attaching luminaires to a support member of a building structure and connecting such luminaires with a source of electricity comprising:

• a central housing member having a top member, a front wall extending down from said top member, a rear wall opposed to said front wall extending down from said top member, a first side wall adapted to join said front wall, top member, and rear wall, and a second sidewall opposed to said first sidewall adapted to join said front wall, top member and rear wall, said sidewalls each including a plurality of circular knockout means of varying diameters for providing circular apertures of varying diameters, whereby said circular apertures receive such support members to attach such luminaire to such support members, and a terminal for receiving electrical wires from such source of electricity;
• a ballast housing interconnected with said central housing and detachable therefrom;
• a fuse housing having at least one fuse member interconnected with said central housing and detachable therefrom, said fuse housing being in communication with said terminal of said central housing and said ballast housing whereby said fuse housing receives electricity from said terminal and directs such electricity to said ballast housing;
• a means for interconnecting said fuse housing and said ballast housing with said central housing including a resilient two-step retaining clip fixed to said ballast housing, said retaining clip having a first tab member adapted to engage said central housing and interconnect said ballast housing with said central housing and a second tab member adapted to engage said fuse housing and interlock said fuse housing with said ballast housing when said fuse housing is interconnected with said central housing, whereby said fuse housing must be disengaged from said second tab member and removed from interconnection with said central housing before said ballast housing and said first tab member are disengaged from said central housing.
