  • Patent number: 10041283
    Abstract: A snap hinge with damped closing includes a first articulated quadrilateral defined by a coupling plate associated with a fixed element, a first lever and a third lever, which are articulated to the coupling plate, and a second lever interposed between the preceding levers and is articulated thereto. A second articulated quadrilateral has a fixing plate associated with a movable element with which are associated and articulated respective ends of the second lever and of a fourth lever, the opposite end of which is associated and articulated with the first lever. The plates have various arrangements with respect to each other, rotating about a substantially horizontal rotation axis as the hinge moves between the open and closed configurations. The hinge has at least one damping element that acts during closing and is interposed directly between the coupling plate and the second lever.

  • Patent number: 9803405
    Abstract: An adjustable snap-acting hinge is provided. The hinge includes a first articulated quadrilateral and a second articulated quadrilateral, which can move on a working plane and share a first lever and a second lever and are provided respectively with a plate for coupling to a first element and with a plate for fixing to a second element. A contrast element is associated with the coupling plate and can be arranged in at least one position for use, which lies between a first position in which the contrast element is arranged at a maximum distance from the point of the first lever, and a second position in which the contrast element is arranged at a minimum distance from the point of the first lever. The hinge also includes locking means for keeping the contrast element in the position for use.
