Abstract

Hinge, which is essentially characterized by two flat branches joined by a rivet articulated by one of its ends, in the manner of a compass, with the particularity that between the surfaces of the two ends that form the articulated joint is arranged a tiny ball partially embedded in a small hole disposed in one of the branches or legs, of a diameter somewhat lower than that of the ball, so that it rotates with the said leg in its movement, until reaching the position of maximum opening of the hinge, is say when both legs are substantially in extension, said ball comes to coincide with a notch or slit correspondingly arranged in the other piece, said notch or slit being surrounded by a small internal rim representing a hard point that must be overcome to achieve the total opening and therefore the fit of the ball in the notch, and which in turn represents the brake or retention that prevents the hinge from closing e, if not exerting a sufficient force, to be able to overcome the corresponding resistance to the passage of the ball, from the inside of the notch towards the outside, above said flange, fixing both branches of the hinge in question by means of holes arranged in the ends opposite the joint on both legs or branches.
