Patent number: 8573876Abstract: A ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.Type: GrantFiled: March 15, 2005Date of Patent: November 5, 2013Assignee: World Wide Stationery Manufacturing Company, LimitedInventors: Hung Yu Cheng, Ho Ping Cheng, Chun Yuen To

Patent number: 6174100Abstract: A binding assembly includes first and second sheet retaining members which are releasably attached to a base member by first and second latching mechanisms. The sheet retaining members include a pair of side members which support a pair of pins and tubes onto which sheets of paper or other materials are placed. Each of the side members includes an engaging rod which is receivable in a channel provided in the base member to retain the sheet retaining members to the base member. Each of the latching mechanisms are independently pivotable about an axis perpendicular to the pins and tubes from a retaining position where the sheet retaining members are constrained to the base member, to a releasing position where the sheet retaining members may be detached from the base member.Type: GrantFiled: December 22, 1998Date of Patent: January 16, 2001Assignee: Leco Stationery Manufacturing Co., Ltd.Inventor: Jun Ming Song

Patent number: 6155737Abstract: A binder ring mechanism (16) has a plurality of binder rings (18a-18c) for holding sheets of paper. Each binder ring includes a fixed section (20) and a movable section (22). All of the movable binder ring sections are commonly mounted on a bolt (36). A lever arm (52) is attached to one end of the bolt for movement of the lever arm to move the bolt and the binder ring sections mounted on the bolt. The bolt is movably mounted on a cover piece (24) for both rotational and sliding movement of the bolt. A recess (58) is formed in an endwall (56) of the cover piece and the lever arm includes a latch member (60) received in the recess to latch the lever arm in place when the binder rings are closed so to prevent inadvertent movement of the lever arm which might cause the binder rings to open. In addition, the cover piece has flaps (82, 84) extending diagonally outwardly therefrom for storing writing instruments in a ring binder (10) in which the binder ring mechanism is installed.Type: GrantFiled: April 30, 1999Date of Patent: December 5, 2000Assignee: U.

Patent number: 5224788Abstract: A Direct Access Modular Binder containing one or more posts. Each post is comprised of two or more interconnected independent locking modules. These locking modules can easily be inserted or removed to change the length of the post to efficiently accommodate varying amounts of paper. The modules additionally function to permit direct access for insertion/removal of pages or modules anywhere along the post. The modules in the post may contain a telescoping feature. The module(s) containing a telescoping feature are optimally positioned at the end(s) of the post and fixedly attached to the post holding strips. The strips, which hold the posts' ends, may be hingedly attached to the front and back covers. The telescoping feature permits the binder to be automatically compacted (when not in use), for efficient storage, and temporarily expanded (when in use), to provide space for the user to insert/remove paper or modules. The modules which make up the post are easily locked and unlocked.Type: GrantFiled: July 23, 1992Date of Patent: July 6, 1993Inventor: Anna B. Freed
