Abstract

Abstract A light support portion is interconnected to a first spring means. The first spring means is interconnected with a second spring means by an intermediate relatively rigid means which may include a swivel joint connected at an intermediate point thereof. The second spring means is interconnected with a mounting means which movably mounts the lighting fixture for movement with respect to a support means, the lighting fixture being supported in a generally horizontal relationship. The second spring means is shorter and more rigid than the first spring means and serves mainly to absorb vertical forces while the first spring means absorbs both vertical and horizontal forces.

Claim 1
Independent Claim 70 words
A lighting fixture comprising a light support portion, a first spring means interconnected with said light support portion, a second spring means, intermediate relatively rigid means connected between said first and second spring means, a swivel joint connected to an intermediate portion of said relatively rigid means, and mounting means interconnected with said second spring means to movably mount the lighting fixture with respect to a support means for movement.
Claim 2
Dependent Claim 70 words
A lighting fixture comprising a light support portion, a first spring means interconnected with said light support portion, a second spring means, intermediate relatively rigid means connected between said first and second spring means, a swivel joint connected to an intermediate portion of said relatively rigid means, and mounting means interconnected with said second spring means to movably mount the lighting fixture with respect to a support means for movement.
Claim 3
Dependent Claim 94 words
A lighting fixture comprising a light support portion which includes a light socket, a first spring means interconnected with said light support portion, a second spring means, intermediate relatively rigid means connected between said first and second spring means, mounting means interconnected with said second spring means to movably mount the lighting fixture with respect to a support means for movement, and wherein said first and second spring means, said relatively rigid means and a portion of said mounting means are all of tubular construction, and electrical lead means extending through said tubular means.
Claim 4
Dependent Claim 94 words
A lighting fixture comprising a light support portion which includes a light socket, a first spring means interconnected with said light support portion, a second spring means, intermediate relatively rigid means connected between said first and second spring means, mounting means interconnected with said second spring means to movably mount the lighting fixture with respect to a support means for movement, and wherein said first and second spring means, said relatively rigid means and a portion of said mounting means are all of tubular construction, and electrical lead means extending through said tubular means.
Claim 5
Dependent Claim 15 words
