Patent ID: 7543356

Claim:
A snap hinge for supporting closure elements, comprising a first articulated quadrilateral and a second articulated quadrilateral, which share a first lever and a second lever and have, as their base element, respectively, a coupling plate for coupling to a component designed to be fixed and a plate for fixing to a closure element, at least a first elastic means which acts on at least one of said articulated quadrilaterals, and a device for fixing said coupling plate to said component, wherein said fixing device comprises a complementary plate, which is adapted to be superimposed on said coupling plate, means for anchoring said complementary plate to said component, rectilinear guiding means for rectilinear guiding of said coupling plate whereby said coupling plate is slidable alternately along a direction which is substantially parallel to the plane formed by said component, said rectilinear guiding means being formed in said complementary plate, actuation means for actuating said coupling plate for sliding along said guiding means, and stop means for stopping the sliding of said coupling plate, said stop means comprising at least one recess formed in said complementary plate and at least one stop tooth adapted to engage said at least one recess, wherein said coupling plate comprises two bases for contact against said component that have respective sides protruding therefrom, the sides being mutually connected by a connecting bridge and being each provided with at least one hole, said bases being slidingly associated with said guiding means, and wherein at least one corresponding pivot is further provided that has opposite ends thereof accommodated each in a respective said at least one hole for articulation of one of said first and second articulated quadrilaterals and of said first elastic means, said at least one stop tooth being formed by an end head provided on at least one of said opposite ends of said at least one pivot accommodated in a said at least one hole provided on a said side, the end head protruding from said side.
