Snap hinge with damped closing

A snap hinge with damped closure, comprising:

• a first articulated quadrilateral and a second articulated quadrilateral each defined by pivot points and which share a first lever and a second lever;
• a coupling plate connected to a first element and the first articulated quadrilateral;
• a fixing plate connected to a second element and the second articulated quadrilateral, the hinge being movable alternately between an open configuration and a closed configuration, wherein the plates have different arrangements with respect to each other wherein in the open configuration the plates are substantially parallel and in the closed configuration, wherein the plates are substantially perpendicular;
• and
• at least one damping element that is interposed between the second quadrilateral and the fixing plate for damped transition from the open configuration to the closed configuration or vice versa,
• wherein the second articulated quadrilateral comprises a first arm that is articulated to the fixing plate and to an end of the first lever, the at least one damping element being interposed between the fixing plate and the first arm,
• wherein the at least one damping element comprises a main body in which a stem is slidable axially, the main body having a first end rotatable with the fixing plate and the stem having a second end movable with respect to the first end and is rotatable with the first arm, the at least one damping element movable alternately between a compression position, in which the first and second ends are mutually closer and the hinge is in the open configuration, and an extension position, in which the first and second ends are mutually spaced and the hinge is in the closed configuration,
• wherein the fixing plate comprises a second fulcrum that is hinged to the first end, the second fulcrum being spaced further from the fixing plate with respect to the first pivot for its arrangement inside the second quadrilateral when the hinge is in the closed configuration and outside the second quadrilateral when the hinge is in the open configuration.

• a coupling plate for being connected to a first element and the first articulated quadrilateral;
• a fixing plate for being connected to a second element and the second articulated quadrilateral, the hinge being movable alternately between an open configuration and a closed configuration, wherein in the open configuration the plates are substantially parallel and in the closed configuration, wherein the plates are substantially perpendicular;
• and
• at least one damping element interposed at least between the first quadrilateral and the coupling plate and between the second quadrilateral and the fixing plate for damped transition from the open configuration to the closed configuration or vice versa,
• wherein the at least one damping element comprises a cylinder and a stem that slides axially within the cylinder, the cylinder defining a first end and the stem defining a second end, the at least one damping element movable alternately between a compression position, in which the first and second ends are mutually closer when the hinge is in the open configuration, and an extension position, in which the first and second ends are mutually spaced when the hinge is in the closed configuration.
