Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
Easel type ring binder which has front and back covers, a ring mechanism affixed within said binder and a binder support comprising a generally U-shaped member having a cross-bar portion at its outer end and two parallel, laterally spaced leg portions, each of said leg portions include a hinge at corresponding locations along the length thereof whereby an outer end portion of the support is pivotable relative to the inner portion thereof, at least one of said hinges including stop means for limiting the pivotable movement of the outer end portion of the support to a predetermined acute angle relative to the inner portion, said binder including means for telescopically receiving therein substantially the full length of the leg portions of said support member.
Claim 2
Dependent Claim
124 words
Easel type ring binder which has front and back covers, a ring mechanism affixed within said binder and a binder support comprising a generally U-shaped member having a cross-bar portion at its outer end and two parallel, laterally spaced leg portions, each of said leg portions include a hinge at corresponding locations along the length thereof whereby an outer end portion of the support is pivotable relative to the inner portion thereof, at least one of said hinges including stop means for limiting the pivotable movement of the outer end portion of the support to a predetermined acute angle relative to the inner portion, said binder including means for telescopically receiving therein substantially the full length of the leg portions of said support member.
Claim 3
Dependent Claim
41 words
Easel type ring binder as set forth in claim 1, in which the inner and outer portions of said support member are pivotable to generally coplanar relationship for telescopically fitting the leg portions thereof within said receiving means of said binder.
Claim 4
Dependent Claim
61 words
Easel type ring binder as set forth in claim 2, in which said receiving means comprises a pair of tubular sheaths disposed within the said binder along the side edges of the ring mechanism, said sheaths and said support member including interengageable stop members for limiting the extent of withdrawal of the leg portions of the support member from said sheaths.
Claim 5
Dependent Claim
90 words
Easel type ring binder as set forth in claim 2, in which said support member is a rod of circular cross-section, said tubular sheaths being circular in cross-section and dimensioned to slidingly receive therein the leg portions of the support member, each of said sheath including a longitudinal cutout having a length approximately equal to the portion of said support member measured from the hinges to the cross-bar portion, a lateral projection on the inner end portions of each of said legs which fits slidably into each of said cutouts.
Claim 6
Dependent Claim
98 words
Easel type ring binder as set forth in claim 2, in which said support member is rectangular in cross-section and slidably fits within said tubular sheaths which are also rectangular in cross-section, a wall portion at each of said sheath being struck inwardly to form a stop tab and each of said leg portions of the support member being provided with a laterally extending projection adapted to engage said stop tab to limit the extent of withdrawal of the stop member to a distance approximately equal to the length of the outer end portion of the support member.
Claim 7
Dependent Claim
33 words
Easel type ring binder as set forth in claim 3, in which said sheaths are formed along the outer side edge portions of a plate which provides the base for the ring mechanism.
