Abstract
An easel hinge includes an outer hinge plate and an inner hinge plate interconnected with each other for relative pivotal movement therebetween. The outer hinge plate has a relatively flat leaf portion terminating in a curled barrel at one side thereof and at least two spaced apart notches formed in the curled barrel. The inner hinge plate has a relatively flat leaf portion and at least two spaced apart lobes extending from the inner hinge plate leaf portion in a plane generally perpendicular to the plane of the inner hinge leaf portion. The lobes are received in the curled barrel of the outer hinge plate through the notches of the curled barrel for permitting relative rotational movement of the inner hinge plate with respect to the outer hinge plate. Lugs formed on the lobes limit the relative rotational movement of the hinge plates and prevent the longitudinal movement of the plates with respect to each other. The lugs permit the relative rotational movement of the hinge plates between a substantially closed position in which the leaves of the hinge plates are generally face-to-face and an open position in which the leaves of the hinge plates are separated at a desired angle of s…
