ABSTRACT:
A post designed for sign or guide marker use having sufficient longitudinal rigidity to withstand a force driving it into the ground and sufficient elasticity to permit nondestructive deformation upon impact by a moving object, with subsequent restoration to an original, upright position. Various construction materials and/or structural configurations are disclosed for obtaining this dual character without incurring high production and material costs.
