Abstract
A modular binder ring is disclosed having a disk shaped central portion, an aperture formed substantially in the center of the central portion, and an annular outer rim formed on the periphery of the central portion. The outer rim includes an arcuately shaped outer surface configured as an outer segment of a circle, and has an axial width greater than the axial width of a central portion. Further, there is disclosed a loose leaf modular binder system comprising at least two modular binder rings, with a spine rod extending through the aligned apertures, capable of binding a plurality of loose leaf paper sheets of different lengths and widths. The paper sheets have die cut perforations on one edge sized to fit about the outer rim of the binder rings. The spine rod enables the bound pages to be removably suspended from a storage rack. In another embodiment, the pages are bound to the binder rings without the spine rod extended through the apertures.
