Patent ID: 7338034

Claim:
An elastomeric spring, comprising: an elongated elastomeric body for absorbing, dissipating and returning axial loads applied thereto over a full length of said elastomeric body defined between first and second longitudinal ends thereof, and with said elastomeric body defining a longitudinal axis and having an outer surface extending between said first and second ends, with the outer surface on said elastomeric body having four generally equal and generally planar sides, with each generally planar side of said outer surface being disposed a generally common distance from one side of and generally parallel to the longitudinal axis of said spring so as to reduce radial bulging of said spring in all directions when an axial compressive force is applied to said spring, and wherein the outer surface of said elastomeric body further includes four radiused corner sections extending between said first and second ends of said elastomeric body and disposed a substantially common distance both longitudinally and laterally from each other, with one radiused corner section being disposed between any two adjoining generally planar sides on the outer surface of said elastomeric body so as to minimize stress concentrations in said elastomeric body when an axial compressive force is applied to said spring.
