ABSTRACT:
An easel hinge for supporting picture frames and the like comprises two hinge plate members each including a tubular wall. The tubular wall of one hinge plate member is inserted in the tubular wall of another hinge plate member with at least some non-congruent portions whereby the inner tubular wall can be rotated within the outer tubular wall. The outer tubular wall is open and has at its open edge a substantially straight lower end wall portion. When the inner hinge plate member strikes against the substantially straight lower end wall portion of the outer hinge plate member the plates are retained in the end angular position, and further angular displacement of the hinge plate members relative to each other is prevented.
