摘要：A ring mechanism for retaining loose-leaf pages comprises a housing and ring members for holding loose-leaf pages that are moveable relative to the housing between an open and closed position. An actuation system moves the ring members and includes hinge plates pivotally mounted on the housing and a lever actuating pivoting movement of the hinge plates in at least one direction (e.g., moving the hinge plates and ring members to the open position). The lever is connected to a travel bar (45) that moves lengthwise of the housing between a position blocking pivoting movement of the hinge plates and a position allowing pivoting movement of the hinge plates. At least one of the lever and the hinge plates deforms when the lever moves to delay pivoting movement of the hinge plates so that the lever may move the travel bar so that it does not block movement of the hinge plates.
