The loose-leaf notebook binder has a plurality of ring assemblies 10 each with rotational freedom with respect to support member 12. A cover 14 having front and back sections is attached to support member 12.

Ring assemblies 10 include first and second semicircular members 16 and 18, having a flattened or oval-shaped cross section, as shown in Fig. 2, interconnected by a hinge 20. The end of each of the semicircular members remote from hinge 20 has an arrangement, as indicated in Fig. 3, suitable for forming a spring clasp 22. Apertures 24 in support member 12, for receiving ring assemblies 10, have a shape corresponding to the cross-sectional area of semicircular members 16, 18 to maintain ring assemblies 10 in an upright position at all times when in support member 12 while having the freedom to rotate 360 degrees through the apertures 24.

In operation, selected contents such as an individual sheet of paper stored in any location in, particularly well-filled, binders can be readily removed by simply rotating the ring assemblies 10 to open at the selected sheet.
