Snap hinge for supporting a closure element
First Claim
1. A snap hinge for supporting a closure element adapted to turn with respect to a fixed element comprising:
- a first articulated quadrilateral;
a second articulated quadrilateral, said first and second quadrilaterals sharing a first lever and a second lever, said first and second levers having as a base element, respectively a plate, for coupling to the fixed element and a plate for fixing to the closure element;
elastic means which elastically act between a point of said first lever and a point of said second lever;
a supporting element that is jointly associated with said fixing plate; and
auxiliary elastic means which are arranged in series to said elastic means and have an end that is articulated to said first lever and an opposite end that is articulated to a first pivot that is supported by said supporting element, said supporting element comprising at least one strip and one pair of first flaps that are formed so as to protrude from two opposite edges of said strip and are provided with holes that support opposite ends of said first pivot, said strip being substantially inclined with respect to a plane of arrangement of said coupling plate.

Abstract
A snap hinge for supporting a closure element comprising a first articulated quadrilateral and a second articulated quadrilateral, sharing a first and a second lever having as a base element respectively a plate for coupling to a fixed element and a plate for fixing to a closure element, elastic elements acting between a point of the first lever and a point of the second lever and auxiliary elastic elements are arranged in series to the elastic elements and have opposite ends that are articulated to the first lever to a first pivot supported by a supporting element jointly associated with the fixing plate. The supporting element comprises at least one strip and one pair of first flaps formed so as to protrude from two opposite edges of the strip and provided with holes for the opposite ends of the first pivot. The strip is substantially inclined with respect to the plane of arrangement of the coupling plate.
