ABSTRACT:
An improved two knuckle hinge comprises a pair of adjacent hinge leaves on which long and short axially aligned hinge knuckles are formed. The long hinge knuckle houses a bushing in its end adjacent the short hinge knuckle to act as an anti-friction bearing. A torsion spring may also be housed in the portion of the long hinge knuckle unoccupied by the bushing for urging the leaves together. A pintle, about which the long hinge knuckle pivots, is supported in the short hinge knuckle and extends into and cooperates with the torsion spring, when the torsion spring is present in the long knuckle. Also disclosed is a two knuckle hinge that simulates the appearance of a three or more knuckle hinge. This is accomplished through the use of one or more markings such as grooves in the long hinge knuckle which simulate the appearance of gaps between knuckles.
