Three knuckle hinge with bushing inserts in center knuckle and method of
making same
摘要:
A hinge has a pair of leaves, one of which has a spaced pair of knuckles and the other has a central knuckle disposed therebetween. Disposed in the single knuckle are a pair of tubular bushing inserts received in opposite ends of its passage and having radial flanges disposed between the adjacent knuckles. The two knuckle hinge leaf is engaged with a pair of hinge pin elements extending inwardly from the opposite end of the leaf so as to prevent relative rotation therebetween, while the hinge pin elements extend into and are freely rotatable in the inserts. In the method of assembly, the bearing inserts are placed in the single knuckle leaf, and the two knuckle leaf is then aligned therewith and the hinge pin elements are inserted and engaged with the two knuckle leaf to prevent relative rotation therebetween.
