ABSTRACT:
A swing arm support housing is formed with an upper housing assembly and a lower housing assembly. Each housing assembly includes a pair of openings spaced one from the other but each formed along parallel axis. One opening of the upper housing assembly extends into but not through the housing and is of a size and configuration to be mounted on top of a lamp support post. The other opening of the upper housing assembly extends completely through the housing and is fitted proximate one of its ends with a clamping ring that has a longitudinal slit to permit distortion of the ring, proximate the slit and in a radial direction, to clamp same against the lamp swing arm or hold the swing arm in selected positions. A clamping actuator extends into the housing along an axis perpendicular to the axis of said openings and at a position proximate the second opening to coact with the clamping ring proximate its slit to compress the ring against the lamp swing arm or release the ring therefrom. The lower housing assembly includes a guide ring to receive the lamp swing arm. The two housings are spaced from each other when mounted to the support post and when receiving the swing arm.
