Abstract
A low profile impact absorbing base in which the base comprises downwardly and outwardly tapering top and peripheral walls which collectively define a hollow interior except for resilient deformable ribs, and a central hub integrally formed with the top wall of the base. A separate post is mounted on a carrier sleeve, with the post being constructed to fit into an embedded retaining sleeve or capable of being inserted directly into the ground. The outside surface of the carrier sleeve and the inside surface of the central hub are complementarily configured so that the post and sleeve can be inserted upwardly into the central opening in the hub and frictionally retained therein. The thickness and spacing of the ribs are such that the ribs can be laterally inwardly deformed as a result of sliding impact forces so that such forces can be absorbed without injury to the player. The base is relatively low in height thereby providing an additional safety factor in that players normally tend to slide over the base as opposed to sliding directly into a side wall of the base causing the noted lateral inward deformation.
