Dampening mechanism for coaxially aligned relatively translatable components

摘要

A dampening mechanism includes a pair of coaxially aligned inner and outer components with ends disposed in telescoping relation with an interposed resilient elastomeric member comprising a monolithic polymeric structure comprising a hollow body within the end of the outer component, and receiving the end of the inner component with the body including an attachment portion secured to the outer component, and a support portion supporting the inner component. The body portion includes a plurality of equally spaced webs extending between the attachment portion and support portion. In one form, the body is generally cylindrical and disposed between the inner surface of the outer component and the outer surface of the inner component in telescoping relation and frictionally engaging the telescoping components.

1. A resilient elastomeric member for disposition between ends of coaxially aligned inner and outer components with ends disposed in axially translatable reciprocally slidable telescoping relation comprising:
an elastic energy absorbing hollow elastomeric body having an inner surface sized to receive the end of the inner component and an outer surface sized for disposition within the end of the outer component, said hollow elastomeric body including an attachment portion for securement to the outer component and a support portion for supporting the inner component, said attachment portion comprising a continuous ring extending radially outward of said attachment portion to limit movement of said body relative to said outer component, wherein said elastic energy absorbing hollow elastomeric body elongates to absorb energy on reciprocal movement of the end of the inner component into the end of the outer component and possesses sufficient resiliency to return to its original shape after the elongation force is removed.
