Tubular memory shape material element used as a demountable mechanical assembly part.

摘要

A tubular member (1) made of a material with shape memory, capable of occupying at a temperature below the final temperature of austenitic transformation (Af) a memorised shrunk shape I permitting the insertion or the withdrawal of the member from a fitting housing (2) and at ambient temperature above the transition temperature (Af) a memorised expanded form II ensuring the locking of the member in the housing (2). The change from one memorised state to the other is obtained only by a change in the temperature of the member (1) below or above the transition temperature (Af). Application to assembly members of the dowel, rivet or gudgeon type in the field of joinery, of motor vehicle construction or the like. <IMAGE>
