Abstract
A ring binder mechanism having at least one pair of half-ring members that are movable between a first position, wherein the half-ring members are closed, and a second position, wherein the half-ring members are open, and at least one generally tubular member to facilitate alignment and securement of the at least one pair of half ring members when moved from the second, open position to the first, closed position.
Claims11
A ring binder mechanism adapted to be secured to a base member, comprising:
- a substantially rigid plate member;
- a plurality of pairs of respective half-ring members, each half-ring member having first and second ends, each half-ring member first end being pivotally supported by the substantially rigid plate member and each half-ring member second end being pivotably movable between a first position wherein the pairs of half-ring members are closed and the second ends of the half-ring members are generally together, and a second position wherein the pairs of half-ring members are open and the second ends of the half-ring members are spaced apart;
- and
- at least one tubular member having first and second ends, the first end being disposed over a portion of the second end of one of the half-ring members when the half-ring members are in the second, open position and wherein when the half-ring members are in the first, closed position, the second ends of the half-ring member pair are at least partially disposed with the at least one tubular member.

A method of decreasing the likelihood that paper will become dislodged from a ring binder mechanism comprising:
- providing a ring binder mechanism having a substantially rigid plate member and at least one pair of half-ring members, each half-ring member having first and second ends, wherein the first ends are pivotally supported by the substantially rigid plate member and the second ends are pivotably movable between a first position wherein the at least one half-ring pair is closed and the second ends of the at least one half-ring pair are generally together, and a second position wherein the at least one half-ring pair is open and the second ends of the at least one half-ring pair are spaced apart;
- providing a tubular member having first and second ends, the first end being disposed over a portion of the second end of one of the half-ring pairs when the half-ring pair is in the second, open position;
- and
- closing the half ring pair to the first, closed position such that the second end of the other half-ring pair is disposed within the second end of the tubular member.
