Abstract:
1. A one-piece elastomeric spring, generally rectangular in plan, with a top side, a bottom side, a left side, a right side and having four load bearing and generally rigid arms all joined to and radiating outwardly from a common body portion so as to provide said spring with a generally X-shape, with each arm terminating in a free ended portion such that each load bearing arm deflects independently of the other arms when a force is applied during use of said spring, and with said top side, said bottom side, along with said left and right sides of said spring each having a concave shaped configuration therebetween, and with said one-piece spring being formed from a preform formed from an elastomer which is free of resilient characteristics, and wherein the elastomer from which said preform is created has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1, and with said preform being worked by stretching and compressing said preform such that the molecular structure of said preform is oriented in at least one direction so as to allow a predetermined spring rate to be imparted to said preform whereby transmuting said preform into said elastomeric spring.
