Abstract

L'invention concerne un dispositif de charnière dans lequel est intégrée de manière compacte une fonction permettant de bloquer automatiquement ledit dispositif en position ouverte. Un premier élément de charnière (27) est relié de manière rotative à un second élément de charnière (21) par l'intermédiaire d'un axe de pivot rotatif (28). Un corps de blocage (37) est formé de façon à constituer une pièce unique avec ledit second élément de charnière (21). L'extrémité de base d'un lien de blocage (42) pivote de manière rotative sur le premier élément de charnière (27). Ce lien de blocage (42) comprend une rainure d'ajustage en série (44) et une rainure de blocage (45) fixées sur le corps de blocage (37). Ladite rainure d'ajustage (44) glisse sur le corps de blocage (37) lorsque le premier élément de charnière (27) se déplace dans le sens de l'ouverture et de la fermeture. La rainure de blocage (45) s'emboîte avec le corps de blocage (37) lorsque le premier élément de charnière (27) est complètement ouvert pour bloquer le mouvement de ce dernier dans le sens de la fermeture.
