ABSTRACT:
A hinge structure composed of a supporting hinge and aligning hinge. The supporting hinge is composed of a first and second part one of which has a first bearing with a spherical bearing portion the other a cooperating seat and preferably a cylindrical bearing surface opening therefrom. The first bearing cooperates with seat and the cylindrical bearing surface to support and prevent relative lateral movement of the first part while permitting rotational movement. The aligning hinge is formed of a second bearing having spherical bearing surface portion and a second hinge portion with a cylindrical bearing portion adapted to receive the second bearing in mating relation to permit rotation around the spherical axis of its spherical portion while preventing lateral movement.
