Abstract
A hinge for the temples of eyeglasses and the like, comprises interfitting convex and concave conical hinge members held in engagement by elongated elastic members. The elastic members allow relative movement of the hinge members under stress and then return the members to their normal fitting relationship when the stress is removed. The elastic members, when worn or weak, are easily replaceable by the user.
