Abstract
A mounting system for luminaire assemblies includes a mounting fixture which can be inserted into a tubular pole and secured therein without the need for complicated fasteners or tools. Specifically, the mounting fixture includes a cylindrical fitting with a tapered threaded section in which the depth of the groove forming the threads decreases upwardly along the fitting. A generally circular wire clip is seated within the tapered groove and upon rotation of the fitting relative to the tubular pole an end or detent of the clip engages the inner surface of the pole thereby prevent rotation of the clip. Continued rotation of the fitting relative to the pole advances the clip upwardly in the threaded section toward the more shallow portions of the groove thereby forming a friction fit between the expanding clip, the mounting fixture and the pole. The friction fit minimizes wobble, noise or other vibration between the assembled components and can be released upon reverse rotation of the mounting fixture relative to the pole. Furthermore, the pole may be of any polygonal or circular cross-sectional configuration as is desired.
