<P>PROBLEM TO BE SOLVED: To provide a lever for a ring binder mechanism which is easily locked when ring members are closed and requires no spring component for locking. <P>SOLUTION: Ring members for holding loose-leaf pages are moveable relative to a housing between open and closed positions. An actuation system moves the ring members and includes hinge plates pivotally mounted to the housing and a lever actuating the 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 that moves lengthwise of the housing between a position blocking a pivoting movement of the hinge plates and a position allowing the pivoting movement of the hinge plates. At least one of the lever and the hinge plates deforms when the lever moves to delay the pivoting movement of the hinge plates so that the lever may move the travel bar so that it does not block the movement of the hinge plates. <P>COPYRIGHT: (C)2008,JPO&INPIT |
