Abstract
Abstract A retaining device held in a compact, lensed, task lighting fixture operates to retain the lens in the fixture and to facilitate the removal of the fixture's fluorescent lamp which is otherwise difficult to access. The retaining device is comprised of a strip of resilient material having a base end mounted in a fixed position within the fixture, a resilient middle strip portion shaped to extend around the base end of the fluorescent lamp, and an outwardly biased distal end extending to contact and retain the lens in the fixture housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
A device for retaining a lens element of a lensed fluorescent lighting fixture and for also removing a fluorescent lamp of said lighting fixture which is in close proximity to said lens element, said device comprising a stationary base end adapted to be mounted in a substantially fixed position within the fluorescent lighting fixture adjacent the fixture's fluorescent lamp, a resilient middle strip portion shaped to extend from said base end around said fluorescent lamp for cradling said fluorescent lamp, and an outwardly biased distal end extending from said middle strip portion for contacting the inside of the lens proximate said fluorescent lamp for providing a retention force thereagainst.
Claim 2
Independent Claim
109 words
A device for retaining a lens element of a lensed fluorescent lighting fixture and for also removing a fluorescent lamp of said lighting fixture which is in close proximity to said lens element, said device comprising a stationary base end adapted to be mounted in a substantially fixed position within the fluorescent lighting fixture adjacent the fixture's fluorescent lamp, a resilient middle strip portion shaped to extend from said base end around said fluorescent lamp for cradling said fluorescent lamp, and an outwardly biased distal end extending from said middle strip portion for contacting the inside of the lens proximate said fluorescent lamp for providing a retention force thereagainst.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein said stationary end, middle portion, and distal end are formed of a single strip of resilient material.
Claim 4
Dependent Claim
13 words
The device of claim 2 wherein said strip of resilient material is plastic.
Claim 5
Dependent Claim
25 words
The device of claim 1 wherein said distal end curves inwardly of said device to provide an outwardly biased arcuate contact surface for the lens.
Claim 6
Dependent Claim
32 words
The device of claim 1 wherein said resilient middle portion has a width sized to fit over the metal end portions of a fluorescent lamp without touching the glass of the lamp.
Claim 7
Independent Claim
172 words
A device for retaining a lens element of a lensed fluorescent lighting fixture and for also removing a fluorescent lamp of said lighting fixture which is in close proximity to said lens element, said device comprising a stationary base end adapted to be mounted in a substantially fixed position within the fluorescent lighting fixture adjacent the fixture's fluorescent lamp, a resilient middle strip portion shaped to extend from said base end around said fluorescent lamp for cradling said fluorescent lamp, and an outwardly biased distal end extending from said middle strip portion for contacting the inside of the lens proximate said fluorescent lamp for providing a retention force thereagainst, said distal end curving inwardly of said device to provide an outwardly biased arcuate contact surface for the lens, said stationary end, middle strip portion, and distal end are formed of a single strip of resilient material, and said middle portion having a width sized to fit over the metal end portions of a fluorescent lamp without touching the glass of the lamp.
Claim 8
Independent Claim
172 words
A device for retaining a lens element of a lensed fluorescent lighting fixture and for also removing a fluorescent lamp of said lighting fixture which is in close proximity to said lens element, said device comprising a stationary base end adapted to be mounted in a substantially fixed position within the fluorescent lighting fixture adjacent the fixture's fluorescent lamp, a resilient middle strip portion shaped to extend from said base end around said fluorescent lamp for cradling said fluorescent lamp, and an outwardly biased distal end extending from said middle strip portion for contacting the inside of the lens proximate said fluorescent lamp for providing a retention force thereagainst, said distal end curving inwardly of said device to provide an outwardly biased arcuate contact surface for the lens, said stationary end, middle strip portion, and distal end are formed of a single strip of resilient material, and said middle portion having a width sized to fit over the metal end portions of a fluorescent lamp without touching the glass of the lamp.
Claim 9
Dependent Claim
