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.

Abstract: A bollard mounting system mounts a bollard body to a stationary post mounted in the floor or ground. The bollard mounting system includes a plurality of locking protrusions and a key protrusion coupled with or otherwise integral with the post. The bollard mounting system also includes a keyed collar disposed on the bollard body. When the bollard body and the keyed collar are positioned on the post, the locking protrusions and the key protrusion engage the keyed collar locking the bollard body onto the stationary post. Installation of the bollard body only requires sliding the bollard body with the keyed collar into place over the stationary post. The locking protrusions are not externally accessible and not externally visible after the bollard body is locked in position, which reduces the likelihood of theft or damage to the locking mechanism in an aesthetically desirable manner.
