Publication number: 20110311302Abstract: 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. The first ring members are movable relative to the housing and the second ring members between a closed position and an open position. At least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion. The at least one separately formed ring member is formed separately from the body. The anchor of the separately formed ring member is secured to the body for pivoting movement relative to the body. The anchor can be received in a receptacle in the body adapted to receive the anchor.Type: ApplicationFiled: August 25, 2011Publication date: December 22, 2011Applicant: WORLD WIDE STATIONERY MANUFACTURING CO., LTD.Inventor: Chun Yuen To

Publication number: 20110311300Abstract: 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.Type: ApplicationFiled: August 25, 2011Publication date: December 22, 2011Applicant: World Wide Stationery Manufacturing Co., Ltd.Inventor: Chun Yuen To

Publication number: 20110311301Abstract: 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.Type: ApplicationFiled: August 25, 2011Publication date: December 22, 2011Applicant: WORLD WIDE STATIONERY MANUFACTURING CO., LTD.Inventor: Chun Yuen TO

Patent number: 8043018Abstract: A ring binder mechanism has a housing supporting first and second hinge plates and rings, each ring including first and second ring members. The first ring member is mounted one of the hinge plates and moveable with the hinge plate relative to the second ring member between closed and open positions. An actuating lever for opening the rings is mounted on a pin secured to the housing. Pivoting of the actuator moves a travel bar relative to the hinge plates. A blocking element is secured to the travel bar for conjoint movement therewith between a locking position in which the blocking element blocks pivoting movement of the hinge plates to open the rings and a non-locking position in which the blocking element does not block pivoting movement of the hinge plates to open the rings. A torsion spring on the pin biases the actuating lever to its closed position.Type: GrantFiled: July 15, 2010Date of Patent: October 25, 2011Assignee: World Wide Stationery Manufacturing Co., Ltd.Inventor: Hung Yu Cheng

Patent number: 6007266Abstract: A binder assembly includes a sheet retaining device having a plurality of rings for engaging corresponding holes in sheets of material retained by the sheet retaining device. The sheet retaining device is attached to a cover member by a fastener having a portion which is insertable into apertures in the sheet retaining device and securable thereto by pressing. The fastener includes a rectangular base having deformable claws which become embedded in the cover member when installed to securely hold the sheet retaining device to the cover member. The embedded claws are concealed from an outer surface of the cover member, thereby improving the exterior appearance of the binder assembly.Type: GrantFiled: June 22, 1998Date of Patent: December 28, 1999Assignee: World Wide Stationery Manufacturing Co., Ltd.Inventors: Hung Yu Cheng, Chun Yuen To, Weng Io Ng
