METHOD FOR JOINING SPECTACLES' FRAME BY USING SHAPE MEMORY EFFECT

摘要

PURPOSE: A method for joining a spectacles' frame by using a shape memory effect is provided to join simply a temple or a bridge to a lens rim of the spectacles' frame by inserting therebetween a shape memory alloy such as NiTi. CONSTITUTION: A method for joining a spectacles' frame includes the steps of preparing a bridge(3) or a temple(5) made of a shape memory alloy, reducing a diameter of the bridge(3) or the temple(5) to by fabricating below a phase transformation temperature so as to keep in memory a diameter of the bridge(3) or the temple(5), joining the fabricated bridge(3) or the temple(5) into a pipe having a diameter being larger or equal to that of the fabricated bridge(3) or the temple(5) and welding the pipe to a lens rim(1) of the spectacles' frame.
