Abstract
A vibration or impact isolator for use between bodies and/or structures, such as between a boat and a dock, is formed from a resilient elongated strip of resiliently flexible material of uniform lateral cross-section wherein longitudinal lateral portions of the strip are formed in the shape of open involutes extending through at least 270 degrees in the unbiased or undeformed condition. An intermediate portion or central portion of the strip between the two lateral edges, which connects the involutes, is deformable on mounting of the longitudinal strip to one of the bodies. Such mounting deforms the strip from an initial condition in which it holds the involutes spaced apart from one another to permit access to said intermediate portion between the involutes and a mounted condition in which it biases the involutes into mutual contact to enclose the free ends of the longitudial edges to provide an extended resilient external surface of the element for contact with a second body, such as a boat when the strip is mounted on a dock.
