Abstract:
1. An illumination assembly for mounting a light fixture spaced apart a fixed first distance and position from a vertical surface to be illuminated, the surface mounted in a rigid frame including a catwalk and an electric power conductor, the assembly comprising: fastening means for affixing the assembly to the catwalk; an upper element extending out beyond the catwalk a second distance; a lower element affixed to the upper element parallel thereto, and below the upper element to define a first space therebetween; an elongate tubular member having a distal first end for affixing the light fixture thereto with an internal passage for electric wire for connecting the light fixture to the electric power conductor; the tubular member having a proximal second end pivotally mounted within the first space by a first vertical member that is connected to the upper and lower elements and passes through the second end to enable the tubular member to rotate pivotally about the first vertical member in a horizontal arc between a first position in which the light fixture is at the fixed first distance and position to illuminate the surface and a second position in which the light fixture is adjacent the catwalk for servicing by a worker on the catwalk; a second vertical member that is releasably connected to the upper and lower elements and passes through the second end to provide a means for releasably preventing rotation of the tubular member while in the first position; and the means for releasably preventing rotation being accessible to a worker on the catwalk.
