ABSTRACT:
Easel type ring binder includes a generally U-shaped support member with parallel leg portions slidably fitted into tubular sheaths disposed along the opposite side edges of the ring mechanism of the binder. Each leg of the support member is hinged at corresponding points intermediate its opposite ends for pivotable movement of the outer end of the support member to a binder support position in which the outer portion of the support member is disposed at an acute interior angle relative to the inner portion thereof. The sheaths are slotted to provide stops and the legs include protections engageable with the stops to limit the withdrawal of the legs from within said sheaths.
