Abstract
A shock isolator having a spring members such as a belleville washer for supporting a static weight with the belleville washer toggleable between a support condition and a nonsupport condition with the belleville washer having a collapse force that is sufficiently high so that the belleville washer can support a static load without collapsing in order to normally maintain an elastomer damping material in a condition free or substantially free of static forces. When a dynamic force exceeds the collapse force of the belleville washer the belleville washer toggles to a collapsed condition leaving the elastomer to tensionally respond to both the static and the dynamic forces by expansion and contraction of the elastomer. As the elastomer damps the dynamic forces of shock and vibration the forces on the equipment reach a damped condition where the belleville washer expansion force exceeds the forces on the equipment thereby allowing the belleville washer to toggle to the support condition to again provide a static support.
