- The present invention relates to a light fixture and a foundation for the light fixture. More specifically, the present invention relates to a light fixture foundation that includes laterally offset cableway openings for facilitating the installation of the light fixture foundation, the light fixture and its wiring.
- Conventional light fixture foundations generally include a pipe shaft for holding conduit with electrical wiring to be connected to a light fixture. The pipe shaft includes an anchor at one end for anchoring the shaft in the ground and a base plate at the other end for supporting a light fixture. The light fixture is generally supported by a pole mounted to the base plate. Typical applications of conventional light fixture foundations include supports for street lighting or parking area lighting.
- An example of a conventional light fixture and foundation is disclosed in a Hubbell Power Systems brochure entitled Lighting Foundations, 2 pages, dated February 1999, the subject matter of which is hereby incorporated by reference. The Hubbell Power Systems brochure discloses lighting foundations including pipe shafts of various lengths and diameters. Each pipe shaft has an anchor on a bottom end for threading the pipe shaft into the ground, and a base plate at the top end on which a pole mounted light fixture can be secured, typically using bolts. Electrical conduit extends into the sides of the pipe shaft via opposing coaxial openings. The conduit extends up through the shaft and through an opening in the base plate So the electrical wiring can be connected to the light fixture.
- Since the openings of the pipe shaft for the electrical conduit disclosed in the Hubbell Power Systems Brochure are coaxial, the conduits extending through the openings interfere with each other. As a result, inserting the conduits into the pipe shaft openings and extending the conduits up through the pipe shaft becomes difficult, thus increasing the difficulty and time required to install the lighting foundation.
- Other examples of lighting foundations includes U.S. Pat. Nos. 1,189,459 to Lundin; 1,272,088 to Poole; 1,624,237 to Hanna; 1,693,760 to Lloyd; 1,777,509 to Underwood; 1,807,413 to King; 3,268,651 to Stevenson; and 3,375,620 to Phillips.
- Accordingly, an object of the present invention is to provide a light fixture foundation designed to allow easy installation and attachment with a light fixture.
- Another object of the present invention is to provide a light fixture foundation that eliminates interference and contact between electrical cableways extending through the foundation.
- Yet another object of the present invention is to provide a light fixture foundation having a pipe shaft with laterally offset openings for receiving electrical cableways.
- The foregoing objects are basically attained by a light fixture foundation having a hollow shaft with a tubular wall that extends along a central longitudinal axis. A first cableway opening extends through the tubular wall along a first axis that is substantially perpendicular to the longitudinal axis. A second cableway opening extends through the tubular wall along a second axis that is substantially perpendicular to the longitudinal axis. The second axis is laterally spaced from the first axis such that the first and second axes and the first and second openings are non-coaxial. A support member for supporting a lighting assembly is coupled to the shaft. The support member has a passageway in communication with the hollow shaft for receiving first and second cableways.
