Patent number: 8052343Abstract: A ring mechanism for retaining loose-leaf pages including 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.Type: GrantFiled: July 14, 2009Date of Patent: November 8, 2011Assignee: World Wide Stationery Mfg. Co., Ltd.Inventors: Ze Yu Zhang, Wing Yiu Ng

Patent number: 8047737Abstract: A ring binder mechanism includes a housing, a ring support, and rings for holding loose-leaf pages. Each ring includes a first ring member and a second ring member that are moveable between a closed position and an opened position. An actuator is mounted on the housing for moving the ring members from the closed position to the opened position. A travel bar has at least one locking element and is moveable between a locked position wherein the ring members are locked in the closed position and an unlocked position wherein the ring members are capable of being moved to the opened position. An intermediate connector operably connects the travel bar to the actuator. A biasing member is engageable with the intermediate connector and at least one of the travel bar and actuator for biasing the travel bar toward the locked position.Type: GrantFiled: April 6, 2007Date of Patent: November 1, 2011Assignee: World Wide Stationery Mfg. Co., Ltd.Inventors: Jn Biao Pi, Chun Yuen To, Ze Yu Zhang

Publication number: 20080175652Abstract: 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.Type: ApplicationFiled: January 18, 2007Publication date: July 24, 2008Applicant: WORLD WIDE STATIONERY MFG.
