ABSTRACT:
A loose leaf ring binder has a support for holding up the inner edges of the loose leaf sheets on that side of the rings on which it would be difficult to write. The support is a flat relatively rigid sheet that is swingably connected at its inner or outer edge to one of the binder covers, so that the inclination of the support can be adjusted. Means are provided for maintaining the selected inclination of the support, in the form of a series of teeth on the adjacent outer cover with means on the support selectively engaging with the teeth to adjust the position of the support so as to bring the inner edge of the supported loose leaf substantially level with the rings. The cover can be quite narrow, in the form of a flexible strap secured at one end to the spine of the binder and coacting with the support at its other end.
