DIRECTIONAL LUMINAIRE Filed May 14, 1959 2 Sheets-Sheet l INVENTOR dhcK A/DELSON BY W 79%;?!

ATTOR EYS 2,994,149 DIRECTIONAL LUMINAIRE Jack Endelson, Atlantic Beach, N.Y., assignor to McPhilhen Manufacturing Co., Inc., Brooklyn, N.Y., a corporation of New York Filed May 14, 1959, Ser. No. 813,120 11 Claims. (Cl. 40--130) This invention relates in general to luminaires and in particular to a new and useful directional type of luminaire, including an elongated substantially rectangular housing adapted to be recessed into a wall and having directional panels removably secured within a ceiling or wall cover plate, the plate being hingedly connected to members which are telescopic within the housing.

The present invention is an improvement over luminaires of this type, particularly in the construction of the directional panels and the cover plate, the panels being secured within an elongated recess of the plate and fixed against relative movement with respect thereto by simple securing means. The mounting plate, in turn, is hingedly connected to bracket members which are supported by the lamp housing and which may be pushed upwardly within the housing in order to position the mounting plate flush against the ceiling in its closed position.

Accordingly, it is an object of this invention to provide a wall or ceiling mount type of directional luminaire.

A further object of the invention is to provide a luminaire, including an elongated, rectangular lamp housing which is adapted to be recessed within a wall or ceiling, and a cover plate therefore, including a recess in which is inserted directional panels, the mounting plate being hingedly supported by bracket members which are telescopic into the lamp housing members.

A further object of the invention is to provide a directional luminaire which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages, and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated and described a preferred embodiment of the invention.

In the drawings:

FIG. 1 is a perspective view of a luminaire constructed in accordance with the invention indicating the mounting plate and directional panels supported on the telescopic bracket members and in an opened position;

FIG. 2 is a perspective view similar to FIG. 1 but indicating the mounting plates swung at substantially right angles to the lamp housing; and

FIG. 3 is a fragmentary transverse section.

Referring to the drawings in particular, the invention as embodied therein includes an elongated, rectangular lamp housing generally designated 10, which is fitted within an outer rectangular wall or ceiling mounting shell or plaster frame, generally designated 12, and secured thereto as by a central bolt 14. The outer wall mounting shell 12 is provided with two laterally extending flange portions 16 and 18, having spaced around openings 28 to accommodate screws or similar devices or any other ceiling support for securing the outer shell 12 to a wall stud or plaster lathing. The complete assembly is recessed within a wall or ceiling and secured to a structural member, such as a stud, and then the wall is finished down flush to a lower flange 22 formed on the lamp housing 10.

The lamp housing is provided with socket members 24 and 26 at each end of the interior thereof to accom- Patent modate a lamp, such as a fluorescent bulb 28. Each of the socket members 24 and 26 are connected by means of wire connections which may be brought out through an opening 30 which is stamped out of the end of the lamp housing 10.

In accordance with the invention, the lamp housing is provided with a pair of spaced L-shaped bracket members 32' and 34, one side of each of which is secured to the inner wall of the housing, and the other sides thereof being provided with spaced elongated recesses 36 to accommodate downwardly extending leg portions 38 and 40 of U-shaped supporting members or brackets generally designated 42. The U-shaped supporting members 42 may be telescoped within the housing 18 and they are pivotally connected to spaced upstanding bosses 44 and 46 located at each end of a ceiling cover plate or closure housing generally designated 48.

The ceiling closure housing 48 is substantially rectangular and is provided with bolt openings at each end to accommodate bolts 50 which may be passed thereto and threaded into openings 52 located at each end of the housing 10 on flange portions thereof. The closure housing 48 is provided with a central elongated, substantially rectangular slot 54 in which is positioned a lettered panel or sign assembly generally designated 56.

The lettered panel or sign assembly 56 includes an opaque central plate or panel 58 sandwiched between two translucent plates or panels 60 and 62 having letters imprinted thereon which are illuminated by the lamp 28 located within the lamp housing 10. The lettered plate assembly 56 is held together by spaced lateral-1y extending threaded lugs or stud members 64 and 66 which extend through the plates and are secured on each side by speednuts to hold the assembly of plates tightly together.

In accordance with the invention, the slot 54 of the closure housing 48 is joined by laterally extending crossed recessed areas 68, including raised bearing portions 70 to support each of the stud members 64 and 66. In this position, the top of the plates 60 and 62 extend slightly above the top of a flanged area 72 defined alongside of the slot 54. The plate assembly 56 is secured in position and held against lateral swinging movement by an S- shaped securing clip 74 which is held in position by a pair of bolts 76, which are threaded onto boss portions 78 of the wall closure housing 48.

In FIG. 3, the closure housing 48 and the lettered panel assembly 56 are indicated in a closed position, at Which position light from the lamp 28 is directed downwardly along each of the panels 60 and 62 to illuminate the lettering thereon. In the event that it becomes necessary to change the bulb 28, or to change the lettered panel assembly 56, the bolts 50 are removed and the complete closure housing 48 and lettered panel assembly 56 are suspended on the brackets 42, which are telescoped outwardly from the lamp housing 12. The closure housing 48 may be swung about the brackets 42 to position the latter in the position indicated in FIG. 2. In this position, it is a simple matter to remove the bolts 76 and the S-shaped securing clip 74 and remove the lettered panel assembly 56, if desired.

Thus, the invention provides a directional luminaire which may be easily mounted within a ceiling and which includes a lamp housing 10 which may be completely removed from the ceiling mount 12 if desired. The illuminating source is easily accessible and the arrangement of mounting plate and lettered panel assembly permits easy access and interchangeability of directional signs if desired.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
