Lighting system
First Claim
1. A lighting track for use in public transportation vehicles, said lighting track comprising:
- an outer track having first and second upstanding walls connected together in spaced apart relation by a base portion spanning therebetween so as to together define a first retention channel, said upstanding walls each having top and bottom edges, inner and outer faces, and a downwardly facing first barrier portion;
a receptacle having first and second side walls connected together in spaced apart relation by a spanning portion spanning therebetween so as to together define a second retention channel, said side walls each having top and bottom edges, inner and outer faces, an upwardly facing second barrier portion, and a downwardly facing third barrier portion, and being shaped and dimensioned to fit closely between said first and second upstanding walls of said outer track;
a protective top cover having first and second side walls connected together in spaced apart relation by a lens spanning therebetween, said side walls each having top and bottom edges, inner and outer faces, and an upwardly facing fourth barrier portion, and being shaped and dimensioned to fit closely between said first and second side walls of said receptacle;
a lighting element shaped and dimensioned for placement between said receptacle and said top cover;
wherein, at least one of said first and second side walls of said receptacle and said first and second upstanding walls of said outer track is movable between a respective locking position where said second barrier portion is in intimate engagement with said first barrier portion and a respective unlocking position where said second barrier portion is removed from intimate engagement with said first barrier portion; and
wherein, when said lighting track is assembled, said protective top cover is in place in said second retention channel of said receptacle and said receptacle is in place in said first retention channel of said outer track, such that said first and second barrier portions intimately engage each other in interfering relation and said third and fourth barrier portions intimately engage each other in interfering relation, so as to thereby retain said receptacle in releasable locking engagement within said outer track and to thereby retain said protective top cover in releasable locking engagement within said receptacle.

Abstract
A lighting track for use in public transportation vehicles comprises an outer track having upstanding walls connected together by a base portion, together defining a first retention channel. The upstanding walls have a downwardly facing first barrier portion. A receptacle has first and second side walls connected together by a spanning portion, together defining an second retention channel. The side walls have an upwardly facing second barrier portion, and a downwardly facing third barrier portion. When the receptacle is in place in the first retention channel, the first and second side walls are each selectively movable between a respective locking position where the second barrier portion is in intimate engagement with the first barrier portion and a respective unlocking position where the second barrier portion is removed from intimate engagement with the first barrier portion. A top cover has first and second side walls connected together by a lens. The side walls have an upwardly facing fourth barrier portion. A lighting element is disposed between the receptacle and the top cover. When the protective top cover is in place in the second retention channel of the receptacle and the receptacle is in place in the first retention channel of the outer track, the first and second barrier portions intimately engage each other in interfering relation, and the third and fourth barrier portions intimately engage each other in interfering relation, so as to lock the receptacle within the outer track and to lock the protective top cover within the receptacle.
