A binder mechanism (10) comprises a pair of prong plates (14 and 16) pivotally connected by a retainer spring (12) to toggle between a first raised position and a second lowered position. The prong plates (14 and 16) include a plurality of ring segments (18 and 20) affixed to the prong plates (14 and 16) that are capable of forming loops. A cam mechanism (26) is used to toggle the prong plates (14 and 16) between the raised and lowered positions causing the ring segments (18 and 20) to open or to close to form loops. The cam mechanism (26) is preferably a slider (26) located above the prong plates (14 and 16), the slider (26) having ramps (28) inserted recesses (30) between the prong plates (14 and 16). Preferably, the recesses (30) are located adjacent to where the ring segments (18 and 20) are attached to the prong plates (14 and 16). Cleats (22) may hold the parts of the binder mechanism (10) together and keep the mechanism attached to a binder assembly.

Un mécanisme de reliure (10) comprend deux plaques de soie (14 et 16) rattachées pivotant par un ressort de retenue (12) de manière à alterner entre une première position surélevée et une seconde position abaissée. Lesdites plaques (14 et 16) comprennent plusieurs segments d'anneau (18 et 20) fixes pouvant former des boucles. Un mécanisme à came (26) est utilisé pour alterner les plaques de soie (14 et 16) entre les positions surélevée et abaissée, ce qui provoque l'ouverture des segments d'anneaux (18 et 20) ou leur fermeture pour former des boucles. Le mécanisme à came (26) est de préférence un curseur (26) situé au-dessus desdites plaques (14 et 16), pourvu de logements (30) insérés des rampes (28) entre lesdites plaques (14 et 16). De préférence, les logements (30) sont adjacents à l'emplacement où les segments d'anneaux (18 et 20) sont fixés sur les plaques (14 et 16). Des équerres (22) peuvent retenir les parties du mécanisme de reliure (10) ensemble et maintenir ce dernier fixé sur le dispositif de reliure.
