Foundation shock eliminator

Abstract

A foundation shock eliminator for buildings or machines to dissipate or eliminate shock energy includes an upper block, a lower stationary base, a roller and an energy damping coating. The upper block and the lower stationary base have respectively a concave inner surface. The concave inner surfaces face each other. The roller is mounted between the concave inner surfaces. The energy damping coating dissipates the shock energy and is covers at least one of the surfaces of the upper block, the lower stationary base and the roller. Consequently, the foundation shock eliminator will aid the buildings or the machines to resist both vertical and horizontal shocks and diminish the shock effects to the buildings or machines. The energy damping coating will keep the entire foundation shock eliminator from being unstable whether or the foundation shock eliminator is subjected to shocks.
