ABSTRACT:
An improved olive knuckle hinge is described wherein, shaft and thrust bearings in addition to a compression trapped pivot shaft are utilized to: reduce wear and friction, increase load handling capabilities and to provide for a space between the two hinge knuckles. In this space previously occupied by a thrust bearing, may now be placed a decorative ring, or it may be omitted all together as the weight of the door is no longer transmitted through this space.
