Abstract: A ring binder mechanism that retains loose-leaf pages and has ring members that do not snap together when they close and that easily open and close as pages accumulate. The mechanism includes a housing that supports two hinge plates for loose pivoting motion, moving the ring members apart or together. The mechanism further includes an actuating lever pivotally mounted on the housing. The lever moves a travel bar and locking elements for controllably pivoting the hinge plates, and therefore controllably moving the ring members apart and together. In particular, the locking elements cam the hinge plates to softly close the ring members. When the ring members are apart, the locking elements register with openings in at least one of the hinge plates. When the ring members are together, the locking elements are out of registration with the openings, blocking the hinge plates from pivoting to separate the ring members.

Abstract: A ring binder mechanism for retaining loose-leaf pages has a housing and a pair of hinge plates supported by the housing for pivoting motion relative to the housing. Mounted on each of the hinge plates are ring members which cooperate to form rings for holding the loose-leaf pages. Pivoting motion of the hinge plates causes the ring members to move between a closed position wherein the two ring members form a substantially continuous, closed loop, and an open position wherein the two ring members form a discontinuous, open loop. A lever is moveable relative to the housing for controlling the pivoting motion of the hinge plates. The lever has a locking position for locking the first and second hinge plates in the closed position. A biasing member engages and biases the lever toward the locking position.

Abstract: A ring binder (10) holding sheets (S) of paper (P) has a dual angle ring metal (100). The ring metal includes a pair of leaves (102, 104) hingedly connected to each other for relative movement between them. Binder rings (114, 116, 118) each include a pair of ring halves with one end of each ring half being attached to a separate one of the leaves. A shield (30) covers the leaves. Release levers (140, 142) at each end of the shield are operable to open and close the binder. The leaves, when the ring binder is closed, form a predetermined angle (A) with respect to each other. Each of the leaves has a segment (122a, 122b, 124a, 124b) by which a second angle (B) is formed between the leaves. This second angle is formed such that the pair of leaves are prevented from movement relative to each other by movement of paper from one side of the binder to the other. However, the plates are readily movable to open the binder by movement of one of the release levers.
