Abstract
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.
