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.
