Abstract
The invention relates to an improvement in hinge elements for spectacles, constituted by three elements, of which the first two elements, respectively fast with the front of the spectacle frame and with one of the sides thereof, comprise a male tenon element engaged in a female mortise element, said elements being connected together by a third element constituted by a hinge pin. One of the first two elements of the hinge presents a housing in which is disposed an elastic member which exerts an axially directed braking force acting between the first two elements of the hinge.
