Abstract

Abstract An adapter for electrically and mechanically attaching a lighting fixture to a lighting track which utilizes a body having first and second end portions. The first end portion of the body connects to the lighting track while the second end portion of the body holds the lighting fixture. The body includes a pair of conductors which are each held in a chamber formed by a recess in the body and a door connected to the body. One of the conductors is movable such that it extends further from the body than the other conductor which is compatible with a two circuit lighting track.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 270 words
An adapter for electrically and mechanically attaching a lighting fixture to a lighting track comprising: a. a body including a first end portion and a second end portion, said second end portion being mechanically connected to the lighting fixture; b. a first conductor positioned within said body, said body including a first recess for at least partially enclosing said first conductor, said body also including a first door having a recess for forming a chamber with said first recess of said body, said first chamber including first and second openings for permitting extension of said first conductor from said chamber, said first opening of said first chamber permitting said first conductor to electrically contact the lighting track, said first chamber being sufficiently large to permit movement of said first conductor therewithin, said first conductor being capable of extending further from said body than said second conductor, said first chamber including a stop for limiting extension of said first conductor therefrom; c. a second conductor positioned within said body, said body including a second recess for at least partially enclosing said second conductor, said body also including a second door having a recess for forming a chamber with said second recess of said body, said second chamber including first and second openings for permitting extension of said second conductor from said chamber, said first opening of said second chamber permitting said second conductor to electrically contact the lighting track, said second chamber including means for preventing movement of said second conductor therewithin, and wherein said first and second doors can be opened to allow access to said first and second conductors.
Claim 2
Dependent Claim 270 words
An adapter for electrically and mechanically attaching a lighting fixture to a lighting track comprising: a. a body including a first end portion and a second end portion, said second end portion being mechanically connected to the lighting fixture; b. a first conductor positioned within said body, said body including a first recess for at least partially enclosing said first conductor, said body also including a first door having a recess for forming a chamber with said first recess of said body, said first chamber including first and second openings for permitting extension of said first conductor from said chamber, said first opening of said first chamber permitting said first conductor to electrically contact the lighting track, said first chamber being sufficiently large to permit movement of said first conductor therewithin, said first conductor being capable of extending further from said body than said second conductor, said first chamber including a stop for limiting extension of said first conductor therefrom; c. a second conductor positioned within said body, said body including a second recess for at least partially enclosing said second conductor, said body also including a second door having a recess for forming a chamber with said second recess of said body, said second chamber including first and second openings for permitting extension of said second conductor from said chamber, said first opening of said second chamber permitting said second conductor to electrically contact the lighting track, said second chamber including means for preventing movement of said second conductor therewithin, and wherein said first and second doors can be opened to allow access to said first and second conductors.
Claim 3
Dependent Claim 18 words
The adapter of claim 1 in which said first and second doors are hingedly attached to said body.
Claim 4
Dependent Claim 53 words
The adapter of claim 1 in which said means for electrically connecting said first conductor to the lighting fixture includes said first conductor having a first end portion and a second end portion, and further includes means for mating said first and second end portions of said first conductor within said first chamber.
