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.

Abstract: A self-closing 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 proper alignment. The leaves of the lower hinge are longer than the leaves of the upper hinge so that the unhinged end of a gate to which the self-closing hinging apparatus is attached is higher when the gate is open than when the gate is closed. The action of gravity on the weight of the gate therefore causes the gate to self-close.
