Abstract
A plate-mounted bollard which includes an internal impact absorption mechanism that enables the bollard to absorb impact forces greater than conventional plate-mounted bollards. The bollard makes use of a force transfer process that shifts impact forces to areas better able to resiliently absorb the impact without causing damage to the bollard, the impact absorption mechanism, or the ground in which the bollard is installed. The impact absorption mechanism consists of an internal resilient core rod mounted at its proximal end to a base plate which is fixed to the ground. Impact forces are then transferred through an outer shell to the distal or upper end of the internal resilient core. With energy from the impact force being distributed along the maximum length of the resilient core rod, the rod flexes and the full length of the rod is utilized to absorb the impact energy.
