Abstract
An easel hinge for supporting picture frames and the like comprising an outer hinge plate and an inner hinge plate, both having curled barrels, the inner barrel being positioned within the outer barrel for relative rotational movement therewith without the use of a separate hinge pin. The outer barrel is constructed with relativey open and relatively closed portions, the relatively closed portions adapted to pass through an opening or openings provided in the inner plate so as to more completely encompass at least portions of the inner curl within the outer curl so as to produce a stronger hinge, i.e. one which is extremely difficult to be forced open beyond its predetermined limit.
