ABSTRACT:
A delineator pole is provided which pivots when a force is applied thereto and returns to its original position upon release of the force. The pole includes upper and lower segments with a biasing spring completely housed within the lower pole segment which is held in a support structure. The upper and lower pole segments are joined together by the spring and are held in axial alignment by the mating cooperation of a rounded edge lip portion adjacent the lower pole segment and a rounded grooved flange adjacent the upper pole segment. Whenever the upper and lower pole segments are moved out of axial alignment, the force of the spring together with the rounded edge lip portion and the groove of the flange interact to guide the segments back into axial alignment.
