Abstract
Apparatus includes a mounting plate having a hole in a center portion thereof, a recessed light support member having laterally-extending flanges on each of two essentially parallel sides, and a guide disposed on the top surface of the plate, the guide having a longitudinal section offset from the top surface by a distance greater than the thickness of the flanges, where the flanges of the recessed light support member are slidable laterally between the top surface of the plate and the longitudinal section of the guide. A method of servicing a lighting fixture having a can includes sliding the can laterally from a position where the can is centered over the hole to a position where a servicing space is effected between a perimeter of the hole and the can.
Claims22
A recessed lighting fixture comprising:
- a plate defining a light opening therethrough and having top and bottom surfaces;
- a slidable light support member including (a) a perimeter that defines an illumination passage area and (b) two essentially parallel laterally-extending flanges each having a thickness;
- and
- a guide disposed on the top surface of the plate, the guide slidably engaged by the light support member and adapted for limiting movement thereof in a direction normal to the top surface while allowing movement thereof in a direction parallel to the top surface, the guide includes a pair of spaced channel members each having a longitudinal section offset from the top surface by a distance greater than the thickness of the flanges to form an offset space,
- wherein the flanges of the light support member are slidable in the offset spaces between a first position where the illumination passage area is aligned with the light opening and a second position that allows access via the light opening to space proximate the top surface.

A recessed lighting fixture, comprising:
- a plate defining a light opening therethrough and having a top surface and a bottom surface;
- a light support member on the top surface over the light opening and having essentially parallel laterally-extending members on each of two opposite sides, the laterally-extending members each having a thickness;
- and
- a guide disposed on the top surface of the plate, the guide having a longitudinal section offset from the top surface by a distance greater than the thickness of the laterally-extending members,
- wherein the laterally-extending members of the light support member are slidable between the top surface of the plate and the longitudinal section of the guide, so that the light support member is slidable in a direction parallel to the top surface from a first position where the light support member is aligned with the light opening to a second position where at least a portion of the light opening is not covered by the light support member.
2 more elements
An apparatus comprising:
- a plate having a hole in a center portion thereof and having a top surface and a bottom surface, the hole defining a hole area;
- a slidable light support member having a perimeter, the perimeter defining an illumination passage area;
- a guide mounted to the top surface of the plate and adapted for limiting movement of the slidable light support member in a direction normal to the top surface while allowing movement of the slidable light support member in a direction parallel to the top surface between a first position where the illumination passage area covers the hole area and a second position that allows manual access, via the hole area, to space proximate the top surface;
- and
- first and second mounting brackets secured with respect to the plate and adapted for securing respective lengthwise ends of the plate to a ceiling structure, one of the mounting brackets abutting the light support member when it is in its second position to form a stop for limiting the movement thereof in the direction parallel to the top surface.
2 more elements
A recessed lighting fixture comprising:
- a plate having a hole in a center portion thereof and having top and bottom surfaces;
- a light support member having laterally-extending members on each of two essentially parallel sides, the laterally-extending members including bearings and each having a thickness;
- and
- a pair of parallel spaced guides disposed on the top surface of the plate, each guide having a longitudinal section offset from the top surface by a distance greater than the thickness of the laterally-extending members,
- wherein the laterally-extending members of the light support member are slidable between the top surface of the plate and the longitudinal section of the guide, so that the light support member is slidable between a first position where the hole is covered by the light support member and a second position where at least a portion of the hole is not covered by the light support member.
2 more elements
A method for servicing a recessed lighting fixture, the method comprising:
- providing a lighting fixture including (a) a plate defining a light opening therethrough and having top and bottom surfaces, (b) a light support member on the top surface over the light opening and having essentially parallel laterally-extending members on each of two opposite sides, the laterally-extending members each having a thickness, and (c) a guide disposed on the top surface of the plate, the guide having a longitudinal section offset from the top surface by a distance greater than the thickness of the laterally-extending members, the laterally-extending members of the light support member are slidable between the top surface of the plate and the longitudinal section of the guide;
- sliding the light support member in such direction parallel to the top surface from a first position where the light support member is aligned with the light opening to a second position where at least a portion of the light opening is not covered by the light support member;
- and
- servicing the lighting fixture through the uncovered portion of the light opening.
