Abstract
A recessed lighting fixture includes a trim unit and a socket unit attached thereto. The socket unit includes a generally horizontal upper plate portion, a pair of side plate portions projecting downwardly from the upper plate portion, and two tabs projecting from the lower ends of the side plate portions. The upper plate portion includes two holes adapted to receive mounting screws. Each tab includes a hole for receiving a mounting screw. The trim unit includes a socket-mounting portion having a slot arrangement for receiving two mounting screws carried by the socket unit. The configuration of the socket arrangement depends upon whether the screws are mounted in the upper plate portion or the tabs of the socket unit.
Description
TRIM AND LAMP SOCKET UNIT FOR
RECESSED LIGHTING FIXTURES
This application is a divisional of copending application serial no. 2,117,456 filed August 10, 1994.
Background of the Invention The present invention relates to recessed lighting fixtures and, in particular, to the mounting of a lamp socket to a trim of such a fixture.
In conventional recessed lighting fixtures, a cylindrical housing is mounted within a ceiling, a trim or reflector structure is mounted to the trim, and a lamp socket unit is mounted to the trim.
It would be desirable to be able to mount the lamp socket unit to the trim in a simple manner and also to be able to mount the same type of lamp socket in different trims.
It would also be desirable to provide a mounting arrangement whereby it can be ensured that certain types of lamp socket units, such as a conventional spring-clip type lamp socket unit cannot be mounted to the trim.
Summary of the Invention In a recessed lighting fixture including a trim, the trim including a reflector portion and a generally horizontally socket-mounting portion disposed at an upper end of the reflector portion. The socket=mounting portion has an aperture formed therein of a size suitable for enabling a portion of a socket unit to pass therethrough.
The aperture includes a first slot extending outwardly therefrom, and a second slot spaced from the aperture at a 5'2067-1D

location generally diametrically opposite the first slot.
The second slot includes a wide portion and a narrow portion. The centers of the wide and narrow portions are substantially equally spaced from the first slot. The first and second slots are located such that first and second screws project upwardly from the socket unit positionable within the first slot and the wide portion, respectively.
Then, the socket unit can be rotated about the first screw as a fulcrum to enable the second screw to enter the narrow portion before the screws are tightened down.
The present invention also relates to a lamp socket unit for attachment to a trim element of a recessed lighting fixture. The lamp socket unit comprises a socket element for receiving a lamp, and a flange mounted to the socket unit. The flange includes an upwardly generally horizontal plate portion, two side plate portions projecting downwardly from the upper plate portion, and two tabs projecting generally horizontally from lower ends of the side plate portions. Each of the tabs includes a hole for receiving a mounting screw. The upper plate portion includes two holes for receiving mounting screws.

A lamp socket unit 25 comprises a cylindrical socket element 26 and a flange 28 attached thereto in any suitable fashion, e.g., by screws, rivets or other fasteners. The socket element 26 is conventional and is adapted to threadedly receive a lamp L. The flange 28 includes an upper horizontal plate portion 30, twa downwardly dependent side plate portions 32, and two horizontal tab portions 34 projecting outwardly from the lower ends of_respective side plate portions 32. Each tab IO has a screw 36, 38 projecting upwardly from a threaded hole formed therein.
The flange is sized so that the upper plate portion 38 and the side plate portions 32 can pass upwardly trough the aperture 14, with the tab portions 34 abutting the underside of the upper part Z2 of the trim element. The spacing between the screws 36, 38 is such that the screw 36 can be inserted into the slot 18 while the other screw 38 is inserted into the wide portion 24 of the keyslot 20. Then, the lamp socket can be rotated about the screw 36 as a fulcrum (clockwise in FIG. 3) to bring the screw 38 into the narrow portion 22. Then, by screwing down the screws, the lamp socket will be securely anchored in place.
Depicted in FIGS. 4-6 is another type of trim z5 element 50 which includes a reflector portion 52 and a socket-mounting portion in the form of an inverted U-shaped bracket or yoke 54. The yoke includes a top plate portion 56, and two downwardly dependent side plate portions 58 which are attached to the reflector 52, e.g., by rivets. The trim element 50 is attached to a cylindrical housing in any conventional manner.
The top plate portion 56 includes a central aperture 60 which includes an oblong portion 62 and a slot 64 extending to an edge of the top plate portion.
The flange is sized so that the upper plate portion 38 and the side plate portions 32 can pass upwardly trough the aperture 14, with the tab portions 34 abutting the underside of the upper part Z2 of the trim element. The spacing between the screws 36, 38 is such that the screw 36 can be inserted into the slot 18 while the other screw 38 is inserted into the wide portion 24 of the keyslot 20. Then, the lamp socket can be rotated about the screw 36 as a fulcrum (clockwise in FIG. 3) to bring the screw 38 into the narrow portion 22. Then, by screwing down the screws, the lamp socket will be securely anchored in place.
Depicted in FIGS. 4-6 is another type of trim z5 element 50 which includes a reflector portion 52 and a socket-mounting portion in the form of an inverted U-shaped bracket or yoke 54. The yoke includes a top plate portion 56, and two downwardly dependent side plate portions 58 which are attached to the reflector 52, e.g., by rivets. The trim element 50 is attached to a cylindrical housing in any conventional manner.
The top plate portion 56 includes a central aperture 60 which includes an oblong portion 62 and a slot 64 extending to an edge of the top plate portion.

A pair of keyslots 64 are formed on opposite sides of the central aperture 60, the keyslots 64 being identigal and including narrow and wide portions 68, 70. The keyslots are spaced equidistantly from the aperture 60.
5 The lamp socket 25 is shaped similar to the one described earlier, except tha the two screws 36, 38 protect upw~rc~ly from. two - t~~ade~ ht~les farmed in the upper plate portion 86. Those screws are spaced apart by a distance enabling them to be inserted upwardly through l0 the wide portions 70 of the keyslots. Then, the lamp socket can be shifted linearly horizontally to bring the screws into the narrow portions of the keyslots. By then tightening down on the screws, the lamp socket will be firmly secured in place. Electrical wiring for the lamp socket will extend through the apertures 60.
It will be appreciated that the same lamp socket unit can be inserted'into both types of trims, merely by relocating the location of the screws. The manner of installation is simple in each instance. Also, by making the aperture 14 or 60 of such a size (i.e., too big or too small), it can be ensured that certain socket units (e. g., socket units of the spring-clip type which may not have been approved for use with these trim elements) cannot be attached to the trim.
Although the present invention has been described in connection with preferred embodiments thereof, it will be appreciated by those skilled in the art that additions, modifications, substitutions and deletions not specifically described may be made without departing from the spirit and scope of the invention as defined by the appended claims.
