发明名称 Pole support assembly
摘要 A roadway pole carrying an overhead luminarie or the like is mounted on a support comprising a stationary, hollow base member anchored to the roadway with hardware located within the base. The lower end of the pole is secured to the base by an upstanding collar, and the interior wall of the pole adjacent the collar is reinforced with a pair of sleeve members. Access to the mounting hardware is provided by an opening formed in the sidewall of the base. The opening is sealed by an access door that requires a special tool for its removal. In a break-away version of the support, the collar is secured to a wedge-shaped, break-away coupling. The coupling in turn is mounted in a seat formed on the stationary base member. The wedge-shaped coupling and seat constitute a locking angle and are held together by friction. An optional shear pin may be provided across the coupling-base interface to more securely seat the coupling. However, the coupling separates from the base when the pole is struck by a moving vehicle thereby minimizing bodily injury and property damage.
