  • Patent number: 4332364
    Abstract: An easel of the type having a generally planar material prop and a support to maintain the prop at a desired attitude. The support includes a plate which is adapted to be releasably affixed to a surface and a hinge formed of first and second members each having a base and extending legs. Each member base is secured to a different one of the prop and plate in a manner which allows a selective relative rotational movement between the base and the associated prop or plate. The axis of rotation is generally perpendicular to the associated one of the prop and plate. The legs are secured to each other in a manner which allows a selective relative pivoting movement of the members about an axis spaced from their bases.
