Abstract: A ring binder mechanism for holding loose-leaf pages includes a housing and a plurality of rings for holding the loose-leaf pages. Each ring has a first ring member and a second ring member. The first ring member is movable relative to the housing and the second ring member between a closed position and an opened position. In the closed position, the first and second ring members form a substantially continuous, closed loop for allowing loose-leaf pages retained by the rings to be moved along the rings from one ring member to the other. In the opened position, the first and second ring members form a discontinuous, open loop for adding or removing loose-leaf pages. The first and second ring members are generally mirror images of each other. Each of the ring members has a length and at least two different radii of curvature along the length of the rings.

Abstract: A ring binder has an elongate body and rings. Each ring includes ring members moveable between open and closed positions. The body and rings are made of one or more moldable polymeric materials. The binder suitably includes a retaining system operable to hold the ring members in the closed position. The retaining system has interlocking formations adjacent ends of the ring members that are moveable between a retaining position in which the retaining system holds the first and second ring members in the closed position and a non-retaining position. The ring members and body can suitably be formed together as one piece from a moldable polymeric material.

Abstract: A ring binder has an elongate body and rings. Each ring includes ring members moveable between open and closed positions. The ring members and body can suitably formed together as one piece from a moldable polymeric material. The binder suitably includes a retaining system operable to selectively and releasably hold the ring members in the closed position. When the ring members are in their open position, loose-leaf pages can be added or removed from the rings. Loose-leaf pages can also be moved from one ring member to another when the ring members are in their open position.

Abstract: A ring mechanism has an elongate body made of a moldable polymeric material and rings for holding loose-leaf pages. Each ring includes a first ring member and a second ring member.

Abstract: A binder is configured such that a plane portion is formed on an outer peripheral surface of at least one ring part at a portion intersecting with a back part of the binder, and such that, when a binder holding member of a binding processing machine holds the binder, the plane portion of the binder contacts with a plane table provided on the binder holding member. Because the binder contacts the plane table on the binder holding member when the binder holding member holds the binder, the binder is held in such a state that the binder cannot incline or rotate. Thus, a binding processing operation can be carried out in the binding processing machine while the binder is held in a regular orientation. Accordingly, a mounting failure due to an inclined orientation of the binder and be resolved.

Abstract: A ring binder includes a housing, a driving mechanism moveable relative to the housing, and rings for holding the loose-leaf pages. Each ring has a first ring member and a second ring member moveable relative to each other between a closed position and an opened position. A ring actuator is positionable relative to the housing and operatively connected to the driving mechanism for moving the ring members between their closed and opened positions. A blocking device blocks the ring members in their closed position against movement to their opened position. The blocking device is positionable relative to the housing between a blocking position wherein the ring members are inhibited by the blocking device against movement from their opened position, and an unblocking position wherein the ring members are selectively moveable from their closed position to their opened position by positioning of the actuator. The blocking device is operable independent of the actuator.

Each pair of ring elements also comprise a concave distal end on one element, and a complementary convex distal end on the other element. When the distal ends of the ring elements are moved towards each other, the male and female fasteners reversibly engage with each other so that each pair of ring elements, in cooperation with the dorsal hinge, forms substantially a ring to secure sheet paper by occupying a pre-punched hole in the paper. At the same time, the concave and convex distal ends also engage, so that the sidewalls of the concave distal end engages the convex distal end to protect the fasteners against disengagement by torsional and lateral forces.

Abstract: A safety ring binder mechanism helps prevent finger pinching by requiring simultaneous opposite movement of sliding actuators at both ends of the mechanism in order to open and close the rings. When the actuators are outermost, dimples on the actuators press the blades of the device against the housing, holding the rings open. When the actuators are pushed in, inclined tongues cam the ends of the blades downward, forcing the rings to close and holding them in a closed position.
