In this ring binder, a pair of opposing swing base plates 3 are connected together at two locations near the center of their longitudinal swinging edges 3a by means of a joint mechanism 6 through operative engagement between the recessed joint section 61 having a projection 63 and the extended joint section 62 having a slot 64, so that the opposing swing base plates 3 are pivotally movable together in unison, and the swinging edges 3a are pivotally movable together toward and away from the top face 21a of the recessed section 21 in the fixed base plate 2.
L'invention porte sur un instrument de reliure à anneaux comprenant un mécanisme de raccordement (6) constitué d'un évidement de raccordement (61) pourvu d'un élément en saillie (63) et d'une saillie de raccordement (62) à gorge (64). Ce mécanisme sert à raccorder les extrémités basculantes (3a) de deux plaques d'assise basculantes (3) à proximité de leurs centres respectifs afin de les rendre opérantes par verrouillage mutuel et basculement. Les extrémités basculantes des plaques d'assises basculantes (3) entrent simultanément en contact avec la face supérieure (21a) d'un évidement (21) d'une plaque d'assise fixe (2) et s'en séparent de la même manière.
