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.
