M. DWORKIN ETAL LIGHTING FIXTURES Filed Aug. 2, 1963 Aug. 23, 1966 United States Patent O 3,268,721 LIGHTING FlXTURES Marvin Dworkin, Highland Park, and Robert S. Fremont,

Wilmette, lll., assignors to Halo Lighting, luc., Chicago, Ill.

Filed Aug. 2, 1963, Ser. N0. 299,541 7 Claims. (Cl. 240-78) This invention relates to improvements Vin lighting fixtures land more particularly to arecessed lighting iixture.

'One of the objects of this invention is to provide a recessed lighting xture with a slidable lens or panel which is readily -slidable from a position under the light bulb to a position laterally thereof to expose the light bulb lor Iaccess thereto. Y

In recessed lighting fixtures it is desirable that the light bulb be enclosed and yet that there be Iaccess to it when it is necessary to replace it or for other necessary repairs. The present invention accomplishes .the foregoing in a Ivery simple and inexpensive structure whereby access to the light bulb may be readily obtained yand wherein the light bulb is enclosed in normal operation.

Other objects 'will become apparent as this description progresses.

In the drawings:

FIG. 1 is -a view of the recessed lighting [fixture of this V invention mounted in the ceiling.

FIG. 2 is va sectional view taken on line `22 of FIG. 1.

:"FIG. y3 is a view taken on lines 3-3 of FIG. l.

lFIG. 4 is a view of the sliding member, and

FIGS. 5 and 6 :are fragmentary perspective views taken on lines 5-5 'and 6-6 respectively ot FIG. 4.

The invention includes a genenally rectangular-shaped housing generally indicated at |10, which includes la top wall 12 and a bottom wall 14 spaced therefrom and parallel thereto, connected by spaced side Walls l16 and an end 'wall .18, all of which 'are welded or brazed Itogether to form an integral housing. The opposite end .1K9 of the housing is closed. 'Ihe side walls 16 'are bent to tor-m outwardly extending lower flanges 20 with spaced openings 21 therein. The ilanges 20 rest on the t-op interior face of the ceiling 22 `and are secured thereto by fastening elements 24 which secure :the entire structure in position i-n the recessed portion of the ceiling, las is Iwell understood in -the art.

'libe top wall .12 is provided with an enlarged opening 26 adjacent one end thereof, the diameter of lwhich is slightly less than the length of the housing. The top wall is shaped to provide a downwardly extending annular lip or iauge 27 surrounding said opening. Spaced upwardly extending ears 28 are struck from the top wall.

A cylindrical-shaped bulb housing generally indicated at 30 has its lower end positioned within the rflange 27 and is secured to the ears 28 by suitable 4fastening elements 32, such as screws. The lower end ot .the cylindrical housing 30 is open Iand extends Ipartially into the interior of the rectangular-shaped housing. The top of the cylindrical bulb housing 30 is closed by a cover plate 34 welded thereto.

The bottom w'all 14 has an opening 66 in alinement with the upper opening 26. A downwardly extending annular hange or lip 38 sunrounds the opening 36. A conventional lamp socket 40 is supported on the cover plate 34. A metal conduit 42 leads from said socket 40 to a junction box 44 mounted on the top wall 12 of the housing 10. The conductor wire extends inside the conduit iii-om the 'junction box to the socket. A light bulb 46 is secured in said socket. The reflector 48 is loosely supponted inside the cylindrical housing 30 on :a plurality of spaced `lingers 50 iixedly secured to the housing 30. The lingers 50 have upturned ends 51. The reflector 48 has Y 3,268,721 Patented August 23, v1966 "ice an opening at the top thereof t-o accommodate the light bulb.

Supported within the rectangular-shaped housing is -a slidable member 'generally indicated at 52, best shown in FIG. 4, which supports Ithe lens. The slidable member includes a plate 54 of Igenenally square-shape having its opposite sides tunned down to form side supporting legs 56. The plate is shaped to provide .an vannular upstanding flange 57 which surrounds the central opening 58 of the plate. A removable ring generally indicated at 60 is supported in the opening 58 of .the slidable member 52. The ring has .an annular upstanding llange 62 and is provided with spaced fingers 64 for securing :a lens 66 which is supported on the ring. The term lens includes any member which acts to cover the opening land which permits the light rays to pass therethrough. It may be any translucent or transparent .pane or panel.

The ring with the lens is removably secured to the plate A54 of .the sl'dalble member 52 by providing an extension 67 on the underside of the ring 60 which slides into a depressed stnap portion 68 inthe plate. The ring also has a similarly shaped extension 69 diametrically opposite the extension'67, with a bayonet slot 70 for engagement with a screw 71A secured to the plate. The ring 60, together with the lens I66. therein, may be removed by loosening the screw 7i1 to permit a drop down of the ring so that it can be shifted laterally to permit the extension 67 to be slid out of the strap 68.

The slidable lens supporting member 512 is manually slidable as a unit in the rectangular shaped housing 10 from a position under the cylindrical housing 30 and the light bulb 46 to the side best show-n in full lines in FIG. 3, where it `is slid laterally into the portion of the housing positioned away from the cylindrical housing. The end wall 1'8 of the housing limits its sliding movement in one :direction while an upturned flange 74 on the lower wall at the open end 19 lim-its sliding movement in the opposite direction. The sli-dable member 52 may be slid very easily in either direction by manually engaging the lens or any exposed portion of the slidable member and moving it laterally. The parts tit freely and movement is relatively easy.

When the slidable lens holder or member 52 is positioned -in alinement with the lopenings 26 and 2-8, which is the normal operating position, the light from the light bulb will pass through the lens =66 and in this position the interior of the cylindrical housing is not visible and is not accessible. However, Ias the slid-able holder is slid latertally .to that shown in full lines in FIG. 3, the interior of the cylindrical housing is exposed tor y'access thereto and the light bulb may be replaced or other Work done .to the unit.

As best seen in FIG. l, only the interior of the cylindrical housing is exposed to view. The rectangular housing 10 is completely hidden from view iat all times by virtue of its mounting in the ceiling. The annular ange or lip 38 of the rectangular housing extends through an :annular opening 125 yformed in the ceiling and terminates ilush with the exposed ceiling surface. A trim ring generally indicated `at 74 is inserted inside and held by the annular flange 38 for the purpose of providing a finished or ornamental appearance to the opening. The trim ring 74 has va conically-shlaped body 76 which terminates in an annular outwardly extending flange 78. A plurality of resilient lingers extend outwardly .from the conicallyshaped body I76 and releasably engages the bottom wall 14 of the housing adjacent the opening to hold the trim ring 74 in position, as shown in IFIG. 2.

`lt will be understood that various changes and modiiications may -be made yfrom the foregoing Without departing trom the spirit 'and scope of the appended claims.
