  • Publication number: 20080267691
    Abstract: A ring binder mechanism that retains loose-leaf pages and has ring members that gently close and readily lock together. The mechanism comprises a housing that supports two hinge plates for loose pivoting motion, moving the ring members between an open position and a closed position. A lever causes the pivoting motion of the hinge plates such that the lever is pivotable between a first position in which the ring members are closed and a second position. A spring is engageable with the lever for urging the lever to move the control structure toward the first position.

  • Publication number: 20080175652
    Abstract: A ring mechanism comprises a housing, hinge plates, and ring members mounted on the hinge plates for retaining pages on the mechanism. An actuating lever is mounted on the housing for engaging the hinge plates and pivoting them to selectively move the ring members between an open position and a closed position. A travel bar is provided to block unintentional pivoting movement of the hinge plates when they are in the closed position. The lever pivots in a direction from one lateral side of the housing toward the other lateral side of the housing, i.e., about an axis that is oriented perpendicularly to the longitudinal axis of the housing and that extends upwardly relative to the housing. A ramped surface on the lever, e.g., a helical surface or a cam surface, engages the hinge plates to drive them to their open configuration.

  • Publication number: 20080124166
    Abstract: A ring mechanism for retaining loose-leaf pages comprises a housing, hinge plates, and ring members mounted on the hinge plates for retaining pages on the mechanism. An actuating lever is pivotally mounted on the housing for engaging the hinge plates and pivoting them to selectively move the ring members between an open position and a closed position. A travel bar is operatively connected to the lever for selective movement between a position in which locking elements of the travel bar block the pivoting movement of the hinge plates and a position in which the travel bar allows the hinge plates to pivot. The lever is configured to deform when pivoting the hinge plates to close the ring members to delay movement of the travel bar and locking elements to the blocking position from the onset of pivoting motion of the hinge plates.

  • Publication number: 20080080925
    Abstract: A ring binder mechanism for retaining loose-leaf pages comprises a housing and first and second hinge plates supported by the housing for pivoting movement. Ring members are mounted on the hinge plates for movement with the hinge plates between closed and open positions. Hook-shaped formations on fee ends of the ring members lock the ring members together when closed. The first hinge plate is slidable relative to the second hinge plate in a direction along a longitudinal axis of the housing for disengaging the hook-shaped formations and allowing the ring members to open. An actuator may be mounted on the housing for moving the first hinge plate to disengage the hook-shaped formations. In addition, friction buffers may be positioned between the hinge plates for aiding the sliding movement of the first hinge plate relative to the second hinge plate.

  • Publication number: 20080008519
    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 from the rings. 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.
