ABSTRACT:
A self-closing double hinging apparatus includes an upper hinge, a lower hinge and a reinforcing bar welded to both the upper hinge and the lower hinge to maintain them in predetermined alignment. A gate is attached to the reinforcing bar. The upper hinge includes a horizontal plate attached to a gate post. The horizontal plate has a hole therein. A bearing having a ball surface attached to the top of the reinforcing bar swivelably engaged and is supported by a beveled surface surrounding the hole. The lower hinge includes three leaves and two pivot pins. One end of the first leaf is rigidly attached to the gate port. One end of the second leaf is pivotally connected to a first end of the second leaf by means of the first pivot pin, which is aligned with the bearing. The second end of the second hinge is pivotally connected to one end of the third leaf by means of the second pivot pin, which is also aligned with the bearing. The other end of the third leaf is rigidly attached to the reinforcing bar. The second leaf is twice as long as the first and third leaves. When the gate is closed, the second leaf rests against the first leaf and the third leaf rests against the second leaf. When the gate is opened in either direction, its free end is raised.
