Abstract
A bollard assembly includes a bollard, and a load transfer member disposed in the bollard, and a shock absorber disposed within the load transfer member. A fastener extends through the load transfer member and shock absorber, and secures the bollard, load transfer member and shock absorber to a ground surface. The load transfer member adjoins the bollard so as to be disposed between the shock absorber and the bollard, and the load transfer member is configured so that when an impact force is applied to the bollard, the force is transferred from the bollard to the shock absorber via the load transfer member. The deflection is absorbed by the shock absorber so that the anchor remains undeformed and the ground remains undamaged. Moreover, due to the resilience of the shock absorber, the bollard and load transfer member are returned to a normal, upright orientation upon withdrawal of the impact load.
