ABSTRACT:
A non-handed two knuckle hinge comprises a pair of axially aligned hinge knuckles formed respectively on adjacent edges of two hinge leaves, and a pintle extending through the bore of one hinge knuckle into the bore of the second hinge knuckle. The pintle is secured in the bore of the second hinge knuckle, and the first hinge knuckle is pivotable about the pintle. The hinge includes a first vertical thrust bearing formed between the hinge knuckles for acting as a thrust bearing when the door is attached to the hinge leaf associated with the upper hinge knuckle, and a second vertical load bearing formed between the pintle head and the first hinge knuckle for acting as a thrust bearing when the door is attached instead to the hinge leaf associated with the lower hinge knuckle. Lateral bearing surfaces are provided in the first hinge knuckle for supporting the pintle at least in the vicinity of each end of the bore of the first hinge knuckle. The hinge may be used interchangeably in left-handed and right-handed door installations and inverted in either type of installation without affecting the operation of the hinge.
