Abstract

Cette invention concerne un dispositif de verrouillage et de déverrouillage pour une articulation pliable. Une roue dentée (3) est disposée entre un arbre pliable (1) et un manchon d'arbre pliable (2), et un trou est formé dans le manchon d'arbre pliable (2), de sorte qu'une broche de verrouillage (5) pourvue d'un ressort (4) passe à travers le manchon d'arbre pliable (2) et soit insérée entre les dents de la roue dentée (3). La broche de verrouillage (5) comprend un trou arrondi en retrait (16), et un manchon annulaire rotatif (6) est emmanché sur la broche de verrouillage (5). Une bille élastique en relief (7) correspondant trou en retrait (16) est disposée sur le manchon annulaire (6). Un boulon (13) pour ajuster le serrage est disposé sur le ressort (4). De cette manière, l'articulation pliable peut être verrouillée et déverrouillée.
