Abstract
A tilting hinge, includes a bracket having mount plate portion and a bearing plate portion bent at a right angle in relation to the mount plate portion and in which a bearing hole is formed. A rotating shaft has a mount portion, a large-diameter portion and an externally threaded small-diameter portion supported rotatably in the bearing hole. A first friction washer is provided between the large-diameter portion and one side of the bearing plate of the bracket and has a hole in which the small-diameter portion of the rotating shaft is inserted. A second friction washer is provided in engagement with the other side of the bearing plate and has formed thereof a hole in which the small-diameter portion of the rotating shaft is inserted. A spring washer provided in engagement with the second friction plate and has formed thereof a hole in which the small-diameter portion of rotating shaft is inserted. A lock washer is provided in engagement with the spring washer and has formed thereof a hole in which the small-diameter portion of the rotating shaft is inserted. A locking nut screwed on the small-diameter portion of the rotating shaft presses the lock washer to the spring washer. A part of the small-diameter portion of the rotating shaft, is being tapered and formed to have a noncircular cross section and the hole in the lock washer is formed to have a noncircular shape corresponding to the noncircular tapered part of the small-diameter portion of the rotating shaft.
