Abstract: A ring binder (10) stores hole (H) punched sheets of paper (P). A mechanism (16) is a bolt action mechanism which positively locks binder rings (18) which hold paper in its stored position. 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) and move in unison with the bolt. A manually operable lever (38) is secured to one end of the bolt. When the lever is moved in one direction, the bolt is rotated so to move the movable sections of the binder rings away from the fixed sections and open the binder. Operation of the lever in the opposite direction brings the movable sections back into contact with the fixed sections to close the binder.

Abstract: A ring binder mechanism adapted to be secured to a cover is disclosed as including a substantially rigid upper curved housing supporting a pair of plates to which three pairs of half-ring members are mounted, and a pair of rivets for engagement with the cover. The plates are pivotably movable between a first configuration in which the pairs of half-rings are closed, and a second configuration in which the pairs of half-rings are open. Each rivet includes an anchor plate to abut the cover and at least one claw penetrable into said cover in order to secure the ring binder mechanism to the cover, and the anchor plate includes a number of ridges or troughs.

Abstract: A ring binder (10) holding sheets (S) of paper (P) has a dual angle ring metal (100). The ring metal includes a pair of leaves (102, 104) hingedly connected to each other for relative movement between them. Binder rings (114, 116, 118) each include a pair of ring halves with one end of each ring half being attached to a separate one of the leaves. A shield (30) covers the leaves. Release levers (140, 142) at each end of the shield are operable to open and close the binder. The leaves, when the ring binder is closed, form a predetermined angle (A) with respect to each other. Each of the leaves has a segment (122a, 122b, 124a, 124b) by which a second angle (B) is formed between the leaves. This second angle is formed such that the pair of leaves are prevented from movement relative to each other by movement of paper from one side of the binder to the other. However, the plates are readily movable to open the binder by movement of one of the release levers.

Abstract: A locking booster ring binder mechanism includes a pair of locking levers, each having a tongue which extends through an opening at one end of the leaves of the mechanism. The tongue has a head wider than the opening, so that the head presses up on the leaves to open the rings when the trigger is pressed outward and downward. A pair of legs extend from either side of the tongue along the sides of the opening between the leaves. The legs have blocking protuberances which bear against the sides of the opening, and prevent the leaves from being opened, when the lever is in a locked position, but not when the lever is in an unlocked position.

Abstract: A paper binding device includes a base, two binding ring assemblies, a pull plate, and a bottom plate. By causing the pull plate to displace forwardly and rearwardly in the center of the base, positioning pins on the pull plate may displace in corresponding guide slots of the binding ring assemblies to force the binding ring assemblies to open or close. The pull plate further has stop pieces that may firmly secure the binding ring elements in position when the binding ring assemblies are in a closed state. The pull plate effectively eliminates the problem of small open angle with conventional paper binding devices which make it difficult to bind papers.

Abstract: A ring binder (10) for holding hole punched sheets of paper (P) includes a low profile ring metal (20). A pair of leaves (28, 30) are hingedly connected to each other for relative movement of the leaves to each other. A plurality of binder rings (22, 24, 26) are each formed of a pair of ring halves (22a, 22b, 24a, 24b, 26a, 26b). One end of each ring half is attached to a separate one of the leaves whereby movement of the leaves moves the ring halves to open and close the binder. A shield (40) covers the leaves, and release levers (44, 46) are located at each end of the cover. The levers are operable by a user of the ring binder to open and close the binder. Both release levers extend substantially co-planar to the cover and the length of the cover and release levers generally corresponds to the length of a sheet paper stored in the binder. This allows the overall size of the binder to be smaller than that of a ring binder holding the same size sheets of paper but using a conventional ring metal construction.

A shield (20) covering the leaves has spaced openings (42) through which the ring halves extend. The shield has a plurality of raised sections (44, 46, 48) extending transversely of a longitudinal axis of the shield with one of the raised sections being formed at each binder ring location. Another raised section (52) extends axially of the longitudinal axis of the shield and intersects each of the transversely extending raised sections.
