Abstract
An assembly which includes a door pivotably connected by hinge members to a wall part. Each hinge member includes a knuckle and a pin with the knuckle being connected to either the door or the wall part and the pin being connected to the other of the door or wall part. The knuckle includes a cylindrical opening and the pin is constructed with a central ball part and oppositely extending shanks. The pin is fitted into the knuckle cylindrical opening with the ball part fitting closely or snugly within the opening and the shanks having a free fit within the cylindrical opening. The ball part is rotatable relative to the knuckle with the shanks of the pin being shiftable transversely within the knuckle cylindrical opening to accommodate misalignment between the pin and knuckle.
