<p>A space-saving ring binder (10) is in a collapsed position when not in use, for example, during packing, shipping, storage, occupying shelf space, and in an upright position when in use retaining paper. The thickness of the ring binder (10) is significantly less when in the collapsed position than when in the upright position. The ring binder (10) includes a cover portion (14, 16, 18) and a binding portion (12) attached to the cover portion (14, 16, 18). The binding portion (12) has a plurality of rings (26) rotatably attached to a toggling assembly (22, 24). The rings (26) are pivotal from a collapsed position in which the rings (26) define an acute angle with the toggling assembly (22, 24) to an upright position in which the rings (26) are substantially perpendicular with the toggling assembly (22, 24). The rings (26) may be permanently locked in the upright position.</p> |
