Abstract

Abstract A luminaire ballast mounting system for mounting a ballast housing to a multiple of wiring systems. The ballast mounting system includes a mounting plate having a pair of depressed support runners along two parallel side edges and an elongated slot extending from the center thereof to one of the support runners. A mounting plate slide having a threaded aperture therein is positioned in the elongated slot to facilitate attaching the mounting plate to a threaded conduit, hook or loop. Cover plates on each side of the ballast housing form a pair of rails which slide over the depressed support runners on the mounting plate, and an access cover retains the mounting plate in position over the central portion of the ballast housing intermediate the two ballast housing cover plates. The mounting plate also includes a plurality of knockouts which permit the cover plate to be mounted directly to a three inch or four inch outlet box.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 152 words
A luminaire ballast mounting system for mounting a luminaire ballast housing to a fixture hanging means, said mounting system comprising, in combination; a pair of spaced ballast housing compartments, a splicing compartment interposed between said ballast housing compartments, a cover plate overlying and secured to each of said ballast housing compartments with opposed edges of said cover plates overlying portions of said splicing compartment adjacent each ballast housing compartment, a mounting plate including a pair of laterally extending parallel support runners on opposite edges thereof and an elongated aperture therein extending from an area centrally of said mounting plate toward one of said support runners, said support runners underlying the opposed edges of said cover plates and supporting said ballasT housing, and a mounting plate slide having a threaded aperture therein adjustably positioned within said elongated aperture, said threaded aperture adapted to connect said luminaire ballast housing to said fixture hanging means.
Claim 2
Dependent Claim 152 words
A luminaire ballast mounting system for mounting a luminaire ballast housing to a fixture hanging means, said mounting system comprising, in combination; a pair of spaced ballast housing compartments, a splicing compartment interposed between said ballast housing compartments, a cover plate overlying and secured to each of said ballast housing compartments with opposed edges of said cover plates overlying portions of said splicing compartment adjacent each ballast housing compartment, a mounting plate including a pair of laterally extending parallel support runners on opposite edges thereof and an elongated aperture therein extending from an area centrally of said mounting plate toward one of said support runners, said support runners underlying the opposed edges of said cover plates and supporting said ballasT housing, and a mounting plate slide having a threaded aperture therein adjustably positioned within said elongated aperture, said threaded aperture adapted to connect said luminaire ballast housing to said fixture hanging means.
Claim 3
Dependent Claim 59 words
The luminaire ballast mounting system of claim 1 wherein said mounting plate includes a slot communicating with said elongated aperture and said mounting plate slide includes a threaded bore therein said mounting plate slide being secured in a fixed position in said elongated slot by means of a locking screw extending through said slot and into said threaded bore.
Claim 4
Dependent Claim 54 words
The luminaire ballast mounting system of claim 1 wherein a mounting hook having a threaded end thereon is threadedly received in said threaded aperture in said mounting plate slide, said mounting hook including locking means thereon for securing said mounting plate slide in any preselected position within said elongated aperture in said mounting plate.
Claim 5
Dependent Claim 25 words
The luminaire ballast mounting system according to claim 3 wherein said locking means is a lock nut on the threaded end of said mounting hook.
Claim 6
Dependent Claim 140 words
A luminaire ballast housing including mounting means therefor, comprising: an elongated open topped ballast receiving housing having a reduced sidewall height on one side of the central portion thereof, a cover plate overlying and secured to opposite end portions of said elongated open topped ballast receiving housing, spaced one from the other, the inner edge of each of said spaced cover plates extending into said central portion defined by said reduced sidewall height, a mounting plate having a pair of depressed parallel support runners on each side edge thereof, said support runners underlying said inner edges of each of said cover plates and supporting said ballast housing while the remainder of said mounting plate overlies and closes off said central portion of said open topped ballast housing; and means located centrally of said mounting plate for mounting said ballast housing.
Claim 7
Dependent Claim 140 words
A luminaire ballast housing including mounting means therefor, comprising: an elongated open topped ballast receiving housing having a reduced sidewall height on one side of the central portion thereof, a cover plate overlying and secured to opposite end portions of said elongated open topped ballast receiving housing, spaced one from the other, the inner edge of each of said spaced cover plates extending into said central portion defined by said reduced sidewall height, a mounting plate having a pair of depressed parallel support runners on each side edge thereof, said support runners underlying said inner edges of each of said cover plates and supporting said ballast housing while the remainder of said mounting plate overlies and closes off said central portion of said open topped ballast housing; and means located centrally of said mounting plate for mounting said ballast housing.
Claim 8
Dependent Claim 52 words
A luminaire ballast housing according to claim 5 wherein an access cover is secured to the sidewall of said ballast housing at said reduced sidewall height portion of said ballast housing, said access cover preventing inadvertent removal of said mounting plate from its position underlying said inner edges of said cover plates.
Claim 9
Dependent Claim 75 words
A luminaire ballast housing according to claim 5 wherein said means located centrally of said mounting plate includes an elongated slot in said mounting plate extending from the center thereof in a direction perpendicular to said depressed parallel support runners, said elongated slot terminating adjacent one of said runners, and a mounting plate slide having a threaded aperture therein is adjustably positioned within said elongated slot, said threaded aperture adapted for mounting said ballast housing.
Claim 10
Dependent Claim 63 words
A luminaire ballast housing including mounting means therefor according to claim 7 wherein said mounting plate includes a slot communicating with said elongated aperture and said mounting plate slide includes a threaded bore therein said mounting plate slide being secured in a fixed position in said elongated slot by means of a locking screw extending through said slot and into said threaded bore.
Claim 11
Dependent Claim 58 words
A luminaire ballast housing including mounting means therefor according to claim 7 wherein a mounting hook having a threaded end thereon is threadedly received in said threaded aperture in said mounting plate slide, said mounting hook including locking means thereon for securing said mounting plate slide in any preselected position within said elongated aperture in said mounting plate.
Claim 12
Dependent Claim 28 words
A luminaire ballast housing including mounting means therefor according to claim 9 wherein said locking means is a lock nut on the threaded end of said mounting hook.
