Abstract
Lighting trim attaches to lamp housing by mating one or more trim attachment regions with respective housing attachment regions. Each trim attachment region includes a finger thereon. The finger ends in a downwardly curved lip. Each housing attachment region includes a slot and a detent sector adjacent to and in communication with the slot. The trim's finger and the housing's slot are dimensioned so that the finger can pass through the housing slot when they are aligned with each other. The finger's lip becomes seated into the housing detent sector upon subsequent rotation of the trim with respect to the housing.
Claims19
A trim attachment system for a recessed lighting unit including a lamp housing having a generally cylindrical support and a trim piece having a generally cylindrical portion for attachment thereto, the system comprising at least one first attachment region associated with a first circumferential region on a selected one of said cylindrical support and/or trim piece and at least one second attachment region associated with a second circumferential region on the other one of said cylindrical support or trim piece for mating with the first attachment region,
- the first attachment region including a slot extending along the first circumferential region and having a first length, and a detent sector adjacent to and in communication with the slot and also extending along the first circumferential region, said detent sector includes a detent region and a tooth, the tooth being adjacent to the slot so that the lip of the finger travels over the tooth to reach the detent region,
- the second attachment region including a finger thereon, the finger having a second length smaller than the first length so as to allow the finger to pass through the slot, the finger having a proximal end connected to the selected one of said cylindrical support and/or trim piece and a distal end, the finger having a lip at its distal end for seating into the detent sector when the finger is passed through the slot and the trim piece is rotated relative to the housing.
A trim attachment system for a recessed lighting unit comprising:
- (a) a lamp housing for attachment to a structural support, the housing having a generally cylindrical portion of preselected circumference, the housing having a plurality of first attachment regions spaced along the circumference of its cylindrical portion, each of the first attachment regions including
- (i) a slot extending along the circumference and having a first length, and
- (ii) a detent sector adjacent to and in communication with the slot, the detent sector extending along the circumference;
- and
- (b) a trim piece for attachment to the housing, the trim piece having an upper circumferential region and including a plurality of second attachment regions, each of the second attachment regions associated with a respective one of the first attachment regions and including
- (i) a finger extending from the upper circumferential region and generally following the contour of the upper circumferential region, the finger having a second length smaller than the first length so as to allow the finger to pass through the slot, the finger having a proximal end connected to the trim piece and a distal end, and
- (ii) a lip at the distal end of the finger for seating into the detent sector when the finger is passed through the slot and the trim piece is rotated relative to the housing.
