ADJUSTABLE SNAP-ACTING HINGE An adjustable snap-acting hinge (la, lb), comprising a first articulated quadrilateral (2) and a second articulated quadrilateral (3), which 5 can move on a working plane and share a first lever (4) and a second lever (5) and are provided respectively with a plate (6) for coupling to a first element (101) and with a plate (7) for fixing to a second element (102); further comprising elastic means (8) provided with two opposite ends that can move toward or away from each other and act between a point of the 10 first lever (4) and a contrast element (9) associated with the coupling plate (6); the contrast element (9) can be arranged in at least one position for use, which lies between a first position in which the contrast element (9) is arranged at a maximum distance from the point of the first lever (4), and a 15 second position in which the contrast element (9) is arranged at a minimum distance from the point of the first lever (4) in order to vary the preloading of the elastic means (8); the hinge (la, lb) also comprises locking means (10) for keeping the contrast element (9) in the position for use.
