Abstract

A dual-hinged spring assembly. One assembly comprises two elastomeric arcs including an upper arc having downward ends, and a lower arc having upward ends, the upward ends of the lower arc being movably connected to the downward ends of the upper arc, thereby forming an ovoid spring. Further, when the lower arc is secured against a supporting surface, pressure against the upper arc causes the dual-hinge spring to compress.
