Arch ring binder assembly
First Claim
1. A binder for use in storing sheets of paper having punched holes in them comprising:
- first and second end leafs respectively forming outer covers of the binder;
a single-piece center plate positioned intermediate said respective end leafs for one side of each of said end leafs to be flexibly attached to opposite sides of said center plate for sheets of paper stored in said binder to be enclosed between said end leafs;
ring means carried on said center plate for holding sheets of paper, said ring means including a plurality of single piece binder rings, and being movable from a first and closed position to a second and open position, sheets of paper being inserted into said binder by placing the holes punched in the sheets of paper over an end of said ring means which is exposed when said ring means is moved to its open position;
locking means for locking said ring means in its closed position, said locking means being fixedly secured to one side of said center plate adjacent one of said end leafs, and said locking means securing the exposed end of said ring means in a locked position when said ring means is in its closed position; and
,moving means for moving said ring means from its closed to its open position, an end of said ring means opposite said exposed end of said ring means being fixedly secured to said moving means, and said moving means being located on the opposite side of said center plate from said locking means and adjacent the other of said end leafs, said moving means being pivotally movable in one direction with respect to said locking means to move the first said end of said ring means from its locked position to its exposed position when said binder is to be opened, and movable in the opposite direction when said binder is to be closed.

Abstract
A binder (12) for storing sheets (S) of paper having punched holes (H). First and second end leafs (16, 18) form outer covers of the binder. A center plate (20) is positioned intermediate the end leafs which are flexibly attached (at 16f, 18f) to the center plate to enclose sheets of paper between the end leafs. Binder rings (24, 26, 28) carrier on the center plate hold the sheets and are movable from a closed to an open position. Sheets are inserted into the binder by inserting the holes over an exposed end (24e, 26e, 28e) of the rings when the rings are opened. Locking mechanism (30) locks the rings closed. A mechanism (58) moves the rings from their closed to their open position. One end (24d, 26d, 28d) of the rings attach to a rotatable plate (60). The locking mechanism is located on one side of the center plate adjacent one of the end leafs, and the rotatable plate is located on the opposite side thereof adjacent the other end leaf. The plate pivotally moves in one direction with respect to the locking mechanism to open the rings and in the opposite direction to close them. Substantial quantities of paper are stored in the binder without the rings inadvertently opening became of the quantity of paper stored.
