Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
In a recessed lighting fixture of the type that provides a recess in a wall for receiving therein the light and a baffle member, and which includes a trim ring located at the edge of the recess for shielding the mounting of the fixture in the wall, the improvement comprising, in combination, a frame member providing a cylindrical inner wall bounding the recess, a baffle having a cylindrical end that is adapted to be positioned generally concentrically within said inner wall in spaced relation thereto, said frame member having means for supporting a trim ring, said supporting means being arcuately arranged around the wall of said frame member at different levels, a trim ring having means for releasably coacting with said arcuately arranged means whereby there is provided a releasable, rotational and axially adjustable connection of said trim ring to said frame without separate connector means, said trim ring having an in-turned flange for engaging the baffle to prevent movement of the baffle axially outwardly past said cylindrical inner wall, and the presence of the baffle engaging said in-turned flange cooperating with the trim ring to prevent inadvertent release of the trim ring from the frame member while permitting axial adjustment of the trim ring relative to the cylindrical inner wall of the frame member.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
A construction as in claim 1 wherein said supporting means comprises three sets of supports each arranged in a stepped series for incremental axial adjustment, and the trim ring having three axially extending members with out-turned hooks thereon for cooperation with the three sets of support.
Claim 4
Dependent Claim
21 words
A construction as in claim 1 wherein axial adjustment of the trim ring is effected by rotation of the trim ring.
Claim 5
Dependent Claim
67 words
A construction as in claim 2 wherein the steps of each set of supports are arranged arcuately along the cylindrical inner wall of the frame member, each step having an arcuate extent to fully support the hook, and a raised impediment at the end of each step that is above an adjacent step for preventing a hook from slipping from one step to the next lower step.
Claim 6
Dependent Claim
88 words
A construction as in claim 2 wherein the trim ring includes a sleeve portion and the axial extension members are elongated and lie within the axially projected plane of said sleeve with the out-turned hooks located outwardly of said projected plane of the sleeve, the length of the extension members affording flexibility thereof to permit release of the trim ring from the frame member when the baffle has been moved axially away from the in-turned flange a distance sufficient to expose the distal ends of the extension members.
