Abstract

Combined hand rail and lighting fixture for a walkway, such as a stair flight, characterized by a tubular member with spaced openings in a lower portion of its wall in which are disposed lighting fixtures, each comprising an extruded housing, a reflector for supporting an illuminating bulb, and an extruded arcuate window closing an opening, the housing and reflector forming a space for receiving the requisite electrical conductors. Its construction is such that it inherently prevents entry of water and hence may be employed outdoors as well as indoors. After installation and wiring, the housing is preferably secured to the hand rail and replacement of a bulb may be effected by removal of a pair of securing clips and the window, only, without disturbing the housing or permanent wiring connections.

Claims

1. In an illuminating hand rail arranged to be mounted adjacent a walkway for projecting light downwardly thereon, comprising:

(a) an opaque tube forming said hand rail having an elongated opening of uniform width in the lower portion of the wall thereof, the maximum cross section of said opening defining a reference rectangle of a width and length through which a unitary lighting fixture containing an elongated illuminating bulb may be inserted, said fixture comprising;

(b) an elongated U-shaped housing of uniform cross section having an arcuate bight portion adapted to abut the inner wall of the tube and longitudinal parallel spaced walls of a width substantially that of the width of the rectangle, the outer edges of said parallel spaced walls being arranged to abut the longitudinal edges of the rectangular opening in said tube whereby the interior of said tube is substantially sealed;

(c) an elongated continuous reflector plate secured to the housing along the length thereof forming a first open ended chamber therebetween at one side thereof for receiving electrical wires, and a second chamber at the other side thereof for receiving an illuminating bulb, said second chamber being disposed nearest the outer edges of said parallel spaced walls of said housing,

(d) an illuminating bulb socket secured to the reflector plate and disposed in said second chamber for supporting the bulb,

(e) a window closing said second chamber along the length thereof, said window being removable from the housing to provide access to the second chamber for replacing the bulb, said window including longitudinal parallel walls adapted to be inserted and closely fit between the parallel walls of the housing to substantially seal the interior of the housing and having an arcuate portion between said parallel walls said arcuate portion forming a continuation of the tube outer surface across the rectangular opening when said housing and window are inserted into said tube, and

(f) removable clip means provided at each end of the window and attached to said tube to permit easy removal of the window from the housing for replacement of said bulb.

2. Apparatus in accordance with claim 1 wherein the window is an extrusion.

3. Apparatus in accordance with claim 1 including means for securing the housing to the tube after assembly thereinto and permitting access to the second chamber for replacement of the bulb by removal of the window.

4. Apparatus in accordance with claim 1 including means for closing opposite ends of the second chamber to preclude access to wiring therebeyond.

5. Apparatus in accordance with claim 1 wherein the housing is an extrusion.

6. Apparatus in accordance with claim 5 wherein the housing includes a pair of inwardly directed wings for securing the reflector thereto.

7. Apparatus in accordance with claim 1 wherein the housing includes a pair of longitudinal flanges providing abutments for edges of the window.

8. Apparatus in accordance with claim 1 including a longitudinally spaced like elongated opening in the handrail and a like fixture therein, providing a handrail portion therebetween without an opening in the lower portion thereof, a support secured to said handrail portion and to a walkway barrier disposed adjacent the walkway, and electrical conduits extending through said support, thence through at least a portion of said handrail portion, and thence into said first open-ended chamber for energizing the illuminating bulb contained in the second chamber.

9. Apparatus in accordance with claim 8 wherein said barrier includes a post to which said support is affixed, said electrical conduits also extending through at least a portion of the post.
