Patent number: 8845224Abstract: A desk leaf base has a base formed of a trapezoidal tubular body in a trapezoidal shape in a side view, closed from a bottom surface to a certain height in both sides, and opened in an upper portion therefrom. An inclined front wall of the tubular body is removed from one side to the other side, in a range from the height to a higher height lower than a top surface. A binder mounted along an elongated top surface of the base has an elongated body and rings. The elongated body is mounted along the top surface of the base with an approximately same width as the top surface. The rings are mounted on the body and capable of opening and closing. Each ring includes linear portions that protrude from the body inclining upward on front and back sides when closing.Type: GrantFiled: August 7, 2010Date of Patent: September 30, 2014Assignee: Calendar Kokoku Co., Ltd.Inventor: Yutaka Hirahara

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: 8277140Abstract: A binder for releasably retaining loose-leaves. The binder has a front cover that lies flatly beneath its back cover when the binder is open 360 degrees. The rings of the binder can rotate around an edge of the flatly-folded cover to enable loose-leaves to lie flat above and below the cover. The binder also has a skeleton with a minimal cross-section spine which may be partially or completely embedded in a cover and rotates in relation to parallel front and back covers when the binder is open 360 degrees. The front cover, middle cover and back cover are connected in a way so that they do not interfere with the rotation of the rings. Mechanisms to open and close the rings of the skeleton to allow addition or removal of loose-leafs, and ring shapes to optimize or stabilize the capacity of the binder during operation are also disclosed.Type: GrantFiled: September 8, 2008Date of Patent: October 2, 2012Inventor: James S. Chizmar

Patent number: 7690855Abstract: A binding tool for documents or the like is provided which is capable of suppressing the height of protruded portions from a surface of a base portion thereby to expand a space thereabove, and which is also easy to manufacture and assemble. The binding tool includes a base portion (2) formed of a metal plate, rings (3) that are each mounted on the base portion so as to be selectively changed into a closed ring posture to bind documents or the like and an opened ring posture to open a part of a closed ring for insertion of the documents or the like, and a switching mechanism (5) that is mounted on the base portion and includes a switching lever (4) for switching the rings between the closed ring posture and the opened ring posture. The switching lever has a base end (41) and a free end (42), and a cam member (6) is provided on the base end of the switching member for adjusting the degree of opening/closing of each of the rings according to a rotated position of the free end.Type: GrantFiled: December 8, 2006Date of Patent: April 6, 2010Assignee: King Jim Co., Ltd.Inventors: Tatsuya Haneda, Kouichi Tanimoto

Patent number: 7377386Abstract: The present invention is a system for attaching rigid holders together to form stacks of rigid holders. The present invention relates particularly to stacks of one or more rigid holders for containers holding compact discs and DVDs. The attachment system of the present invention allows for simple and efficient connection between individual rigid holders. Mechanical binding clips are inserted into cutouts on the spine region of rigid holders. The binding clips are flexed to fit within an opening and then un-flexed to lock the rigid holders and binding clips together. Male and female details allow for a secure hold. Extensions within the cutouts have barbs that fit over parts of the binding clips.Type: GrantFiled: August 19, 2004Date of Patent: May 27, 2008Assignee: PTG, LLCInventors: Tatiana L. Gelardi, Anthony L. Gelardi, Michael Thrower

Patent number: 7341390Abstract: A loose-leaf binder has a back, a binder made of a flexible material and attached to the back and two end plugs mounted respectively in ends of the back. The back has two tracks, two side slots and a middle slot. The binder has multiple open rings having two ends. Each plug has two side tines and a middle tine. A notebook with the loose-leaf papers can be easily attached to or detached from the loose-leaf binder by attaching or detaching the open rings of the binder to punched holes in the notebook simultaneously.Type: GrantFiled: May 5, 2004Date of Patent: March 11, 2008Inventor: Sun L Chang

Patent number: 6761497Abstract: For ring binders of externally fitted types it is an essential requirement that they do not interfere with the turning of loose leaves. Conventional binders have had too broad backbone plates supporting binder rings to permit smooth turning of the leaves. The invention provides a loose-leaf binder a loose-leaf binder comprising an elongate first backbone plate having a plurality of first binder half-rings formed at given intervals upright along its outer edge, and a second backbone plate having a plurality of second binder half-rings formed at given intervals upright along its edge opposite to that of the first backbone plate. The first and second backbone plates are adapted to be combined to close the first and second half-rings to form complete binder rings.Type: GrantFiled: May 3, 2002Date of Patent: July 13, 2004Inventor: Kokki Kaneda

Patent number: 6276862Abstract: A binder mechanism comprises a pair of prong plates pivotally connected by a retainer spring to toggle between a first raised position and a second lowered position. The prong plates include a plurality of ring segments affixed to the prong plates that are capable of forming loops. A cam mechanism is used to toggle the prong plates between the raised and lowered positions causing the ring segments to open or to close to form loops. The cam mechanism is preferably a slider located above the prong plates, the slider having ramps inserted through recesses between the prong plates. Preferably, the recesses are located adjacent to where the ring segments are attached to the prong plates. Cleats may hold the parts of the binder mechanism together and keep the mechanism attached to a binder assembly. Preferably, the retainer spring is in the form of a top spring covering both the slider and prong plates.Type: GrantFiled: September 15, 1999Date of Patent: August 21, 2001Assignee: ACCO Brands, Inc.Inventors: Michael Thom Snyder, Timothy Edward McKeown, R.

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. S. Ring Binder CorporationInventor: Paul A. Whaley
