ABSTRACT:
A two-piece bracket assembly is provided for a pedestrian traffic signal unit for mounting the unit on an upright pole. The bracket consists of a first piece which is bolted or strapped to the pole, and a second piece which is mounted on the side of the signal unit. The two pieces are removably hinged together by appropriate hinges, and are shaped to form an enclosure when turned about the axis of rotation of the hinges to a closed facing position. The energizing wires for the signal unit are brought up through the interior of the pole and through an opening in the first piece of the bracket to be connected to a terminal strip in the second piece of the bracket. The terminal strip is connected to wires extending into the signal unit itself, the wires being connected to the electrically energized illuminating elements within the unit. The two hinged pieces of the bracket are held in their closed position by locking bolts emanating from inside the pedestrian signal, or by other appropriate fastener means, such as straps.
