  • Patent number: 4552478
    Abstract: A ring mechanism for mounting on a loose leaf binder has ring elements, for retaining paper, secured to carrier rails within a cover rail. The ring elements are moveable between open and closed positions. The ring elements include bottom portions extending to intermediate locations higher than their lower ends, but arranged to support paper below the top of the cover rail. Additionally, the ring elements are mounted so their first ends are spaced above the binder cover. This arrangement provides operating space for the ring elements, while enabling the ring elements to have a large capacity.
