Plaster frame assembly for recessed luminaires
A plaster frame assembly includes a base plate that has a base wall and a plurality of side walls that extend substantially perpendicular to the base wall from a perimeter of the base wall. The base wall includes at least one regressed pad that has a plurality of perforations. The plurality of perforations receive one or more securing fasteners therethrough to secure or fasten the base plate to the ceiling. Furthermore, the base wall includes one or more sealing features that provide an air-tight sealing for a recessed housing can received through and retained in a can receiving opening formed in the base wall. The one or more sealing features include multiple collar sections that define a groove for receiving a sealing member, and one or more sealing tabs disposed between the multiple collar sections and configured to seal one or more adjustment apertures of the recessed housing can.
1. A plaster frame assembly for a recessed luminaire comprising:
a base plate that includes:
a base wall having a can receiving opening formed in the base wall and configured to receive a recessed housing can of the recessed luminaire therethrough, and at least one regressed pad that includes a plurality of perforations formed in the base wall, the at least one regressed pad integral to the base wall and defined by a portion of the base wall that is raised from a remainder portion the base wall; and
a plurality of side walls that extend substantially perpendicular to the base wall from a perimeter of the base wall;
wherein the at least one regressed pad is disposed between the plurality of side walls and the can receiving opening, and
wherein the plurality of perforations formed in the at least one regressed pad are configured to receive one or more securing fasteners therethough to fasten the base plate in a downward direction toward a ceiling so that a trim ring abuts against the ceiling to eliminate a gap in between the trim ring and the ceiling, when the trim ring is coupled to the recessed housing can.
2. The plaster frame assembly of claim 1 , wherein the base wall further comprises:
a plurality of collar sections that extend inward towards the can receiving opening from at least a portion of a perimeter of the can receiving opening; and
one or more sealing tabs that are disposed in between the plurality of collar sections, each sealing tab extending inward towards the can receiving opening from at least another portion of a perimeter of the can receiving opening and substantially perpendicular to the base wall.
3. The plaster frame assembly of claim 2 , wherein the plurality of collar sections define a substantially annular groove having a substantially V-shaped cross-sectional profile.
4. The plaster frame assembly of claim 3 , wherein the substantially annular groove defined by the plurality of collar sections is configured to receive a substantially annular sealing member that has a substantially triangular cross-sectional profile to create an air-tight seal that seals in between the plaster frame assembly, the ceiling, and the recessed housing can when the recessed luminaire is installed in the ceiling.
5. The plaster frame assembly of claim 2 , wherein the one or more sealing tabs are configured to create an air-tight seal for the recessed housing can by sealing one or more adjustment apertures formed in the recessed housing can.
6. The plaster frame assembly of claim 5 :
wherein the recessed housing can is disposed in the can receiving opening of the base plate such that a bottom edge of the recessed housing can is flush with a lower surface of the ceiling and each adjustment aperture of the recessed housing can is aligned with a coupling aperture of a respective sealing tab.
7. The plaster frame assembly of claim 1 , wherein the plurality of perforations comprise through apertures.
8. The plaster frame assembly of claim 1 , wherein the plurality of perforations include elongated through slots.
9. The plaster frame assembly of claim 1 , further comprising:
a first hanger bar assembly that is coupled to one side wall of the plurality of side walls of the base plate and a second hanger bar assembly coupled to an opposite side wall.
10. The plaster frame assembly of claim 1 , wherein each of the side wall and the opposite side wall comprises one or more attachment tabs that are configured to couple the first hanger bar assembly and the second hanger bar assembly to the side wall and the opposite side wall, respectively.
11. The plaster frame assembly of claim 1 , wherein the base plate comprises one or more coupling and mating features that are configured to couple a junction box to the base plate.
