Patent ID: 8146898

Claim:
An elastomeric compression spring, comprising: an elastomeric body defining a longitudinal axis for said spring, with said elastomeric body being formed with two hollow convolutions between opposed ends of said spring, with the convolutions being integrally formed and joined to each other by a connecting section, with each hollow convolution including wall structure defining an outer surface for said spring, and with the wall structure of each convolution including two angled wall sections disposed to opposed sides of said axis and which angle away from said connecting section and from each other, and with the outer surface of that portion of each angled wall section of each convolution adjacent to the connecting section having a transversely elongated projection extending outwardly from said outer surface of said spring such that when the angled wall sections of one convolution collapse toward the angled wall sections of the other convolution in response to a load being directed along the longitudinal axis of said spring the projections on said convolutions contact and engage with each other thereby enhancing performance characteristics of said spring.
