A hinge is disclosed between the side piece (2) and the endpiece (1) of the frame of a pair of glasses. The side piece and the endpiece are parts (1, 2) made of wire, of which one bears a hinge body (6) which serves as a hinge axis with a coaxial, peripheral groove (7) for receiving a bearing eye which consists of the bent end (3) of the wire of which the other part (1) is made. The bearing eye forms a peripherally open eyelet (8) which can elastically engage the peripheral groove (7). In order to achieve advantageous manufacturing conditions, the wire of which the part (2) that bears the hinge body (6) is made has a bent, hairpin-shaped end piece (3) which form-fittingly holds between its branches (4, 5) the hinge body (6) on both sides of the peripheral groove (7). The cross-piece (10) located between the two branches (4, 5) of the end piece (3) covers the outer side of the eyelet (8), which forms the bearing eye of the other part (1).
L'invention concerne une articulation à charnière entre une branche (2) et un tenon (1) d'une monture de lunettes, la branche et le tenon étant constitués par des pièces en fil métallique (1, 2), dont l'une porte un corps d'articulation (6) servant d'axe de charnière, avec une rainure périphérique coaxiale (7) destinée à recevoir un oeillet support formé par une extrémité incurvée (3) du fil de chaque autre partie (1) et formant une boucle (8) ouverte sur la périphérie et s'engageant élastiquement dans ladite rainure périphérique (7). En vue d'obtenir des conditions avantageuses de construction, l'invention est caractérisée en ce que le fil de la partie (2) portant le corps d'articulation (6) présente une pièce d'extrémité (3) incurvée en forme d'épingle à cheveu entre les branches (4, 5) de laquelle le corps d'articulation (6) est maintenu par liaison de forme des deux côtés de la rainure périphérique (7) et dont la barrette de jonction (10) entre les deux branches (4, 5) recouvre, vers l'extérieur, la boucle (8) de l'autre partie (1) formant l'oeillet support.
