Abstract

Abstract Apparatus for mounting an A.C. ballast and a D.C. emergency lighting system. A first elongated mounting member having first and second portions and a plurality of mounting holes is provided. The first portion is adapted to receive a first enclosure housing an A.C. ballast and an emergency lighting invertor. The second portion is adapted to receive a second elongated mounting member which supports a second enclosure housing a battery for providing emergency power. The second elongated mounting member may also be mounted in a spaced relation to the first elongated mounting member. A plurality of perforations are provided between the first portion and the second portion of the first member for severing the two portions from one another if there are space limitations. There is a raised portion having a slot associated therewith located on the first portion of the first elongated mounting member near the perforations for receiving a tab which extends from one end of the second elongated mounting member. At the other end of the second elongated mounting member there is a mounting hole and a rectangular space. The second portion of the first elongated mounting member also has a mounting hole and a rectangular space at one end. The combination of the rectangular space, holes and raised portion and tab help insure that the second housing containing the battery will be mounted only after the first elongated mounting member is mounted. The second housing containing the battery includes a pair of tabs which are shaped so that they will be wedged into the slot of the raised portion so that the first enclosure and the second enclosure are mounted a small distance from one another for thermal insulation. A thermal protective device is also connected to the ballast to guard against battery overheating during normal operations.

Claim 1
Independent Claim 160 words
Apparatus for mounting an emergency lighting system for starting and operating at least one gaseous discharge lamp comprising: a first elongated mounting member adapted to be mounted to a lighting fixture; a first enclosure to house at least an emergency lighting driving device, said first enclosure being mounted on a first portion of said first elongated mounting member; a second enclosure to house at least a battery for providing emergency power; a second elongated mounting member; means mounting said second enclosure on said second elongated mounting member; means selectively mounting said second elongated mounting member on a second portion of said first elongated mounting member; means maintaining said first enclosure a predetermined distance from said second enclosure for providing thermal insulation, said means maintaining including a pair of tabs connected to one end of said second enclosure, a raised portion on one end of said first portion and a slot associated with said raised portion receiving said pair of tabs.
Claim 2
Dependent Claim 160 words
Apparatus for mounting an emergency lighting system for starting and operating at least one gaseous discharge lamp comprising: a first elongated mounting member adapted to be mounted to a lighting fixture; a first enclosure to house at least an emergency lighting driving device, said first enclosure being mounted on a first portion of said first elongated mounting member; a second enclosure to house at least a battery for providing emergency power; a second elongated mounting member; means mounting said second enclosure on said second elongated mounting member; means selectively mounting said second elongated mounting member on a second portion of said first elongated mounting member; means maintaining said first enclosure a predetermined distance from said second enclosure for providing thermal insulation, said means maintaining including a pair of tabs connected to one end of said second enclosure, a raised portion on one end of said first portion and a slot associated with said raised portion receiving said pair of tabs.
Claim 3
Dependent Claim 39 words
Apparatus as set forth in claim 1 wherein said first enclosure is adapted to house A ballast for operating the at least one gaseous discharge lamp during normal conditions and an invertor for operating the lamp during emergency conditions.
Claim 4
Dependent Claim 25 words
Apparatus as set forth in claim 1 further including means mounting said second elongated mounting member substantially spaced apart from said first elongated mounting member.
Claim 5
Dependent Claim 25 words
Apparatus as set forth in claim 1 further including means mounting said second member to said second portion only after said first member is mounted.
Claim 6
Dependent Claim 87 words
Apparatus as set forth in claim 1 wherein said means selectively mounting said second elongated mounting member on said second portion of said first elongated mounting member includes a raised portion situated on said first elongated mounting member near the junction of said first and second portions, a slot associated with said raised portion, and a tab connected to one of the short ends of said second elongated mounting member; said tab being received in said slot when said second member is mounted on said first member.
Claim 7
Dependent Claim 73 words
Apparatus as set forth in claim 5 further including a mounting first hole and a first cut out area on the opposite end to said tab on said second member, and second hole and second cut out portion on one end of said second portion of said first member whereby said first hole is mounted over said second cut out portion and said first cut out portion is mounted over said second hole.
Claim 8
Dependent Claim 65 words
Apparatus as set forth in claim 5 wherein said tab includes a recess extending partially into said tab for receiving a first screw and a second recess extending longitudinally into another of said short sides of said second elongated mounting member, said second recess for receiving a second screw for mounting said second elongated mounting member substantially spaced apart from said first elongated mounting member.
Claim 9
Dependent Claim 31 words
Apparatus as set forth in claim 1 further including a weakened section between said first portion and said second portion to facilitate severance of said first portion and said second portion.
Claim 10
Dependent Claim 42 words
Apparatus as set forth in claim 1 wherein said first elongated mounting member includes a plurality of linearly related perforations positioned between said first portion and said second portion for aiding in the severance of said first portion from said second portion.
Claim 11
Dependent Claim 246 words
Apparatus for mounting a ballast and emergency lighting system for starting and operating at least one gaseous discharge lamp comprising: a first elongated mounting member having parallel rails along the long sides and a plurality of holes for mounting said first elongated mounting member to a lighting fixture; a first enclosure housing a ballast for operating the at least one gaseous discharge lamp during normal conditions and further for housing an invertor for operating the lamp during emergency conditions; means mounting said first enclosure on a first portion of said first elongated mounting member between said parallel rails; a second enclosure housing a battery for providing emergency power, said second enclosure having a pair of tabs connected to one end, together with tabs presenting a tapering away in width from said one end; a second elongated mounting member; means mounting said second enclosure on said second member; means selectively mounting said second mounting member on a second portion of said first elongated mounting member; a raised portion and a slot associated therewith on said first portion for receiving said pair of tabs; said slot and said tabs being adapted to maintain said first and second enclosures a predetermined distance apart for thermal insulation; a plurality of perforations at the boundary between said first and second portions of said first elongated mounting member to facilitate selective severance of said first and second portions wherein said second enclosure may be mounted substantially spaced apart from said first enclosure.
