Abstract
Improved hinge, which has an axis of rotation introduced into the interior of a succession of rings, ternary tivomente corresponding to one and another part of the hinge, terminating the end rings in both threaded plugs and possibly being the shaft firmly associated with one or more rings of parity other than those with said plugs, characterized in that the repeated plugs apply against the ends of the rotating axle separate casings, producing between these and the axis areas of point support, for which said axis ends in two conical points (Machine-translation by Google Translate, not legally binding)
