Abstract
A spring-loaded hinge suitable for eyeglass frames comprises two hollow members with respective bores and comprising at respective ends complementary articulation surfaces. The two bores open at facing orifices and a connecting part accommodated in the two bores passes through these orifices. An enlarged end of the connecting part is abutted against an inside end surface of one of the bores and its other end is coupled to a spring accommodated in the other bore. The spring is prestressed to urge the articulation surfaces against each other through the intermediary of the connecting part.
