Abstract
A self-uprighting delineator post construction comprises a base that may take a number of different forms and which is capable of being fixed to any suitable stationary object. A delineator post is provided which is of light weight impact resistance construction and may be composed of any one of a number of suitable impact resistant materials. A load cell is interposed between the base and delineator post and incorporates upper and lower load cell which are in abutment and pivotally disposed. The load cell elements are secured by a pair of cables disposed in side-by-side relation and maintained under tensile stress by open or a pair of compression springs which are subjected to a predetermined spring preload. The side-by-side cables fit within aligned passages of the upper and lower load cells which are of elongated cross-sectional configuration and serve to insure return of the delineator post to its properly oriented upright position after being forced toward the horizontal by an impact force.
