Hinge
First Claim
1. Hinge comprisinga fixed support,a mobile support, said mobile and fixed support being at least rotatably constrained one to the other,an elastic means operatively interposed between said fixed support and said mobile support to impose a predefined law of motion to the mobile support with respect to the fixed support over the entire stroke of the mobile support with respect to the fixed support,a controlled motor means for applying a push or a pull force onto said mobile support with respect to said fixed support, anda motion guide bar articulated to said mobile support and coupled slidingly to said fixed support, wherein said motor means apply an axial push or pull force onto said motion guide bar in such a way that the motor performs a maximum of 20-30% of work during the first opening/closing step of the mobile support, and the elastic means performs the remaining 70-90% of work.

Abstract
Hinge for a door which covers at least in part a compartment, of the type comprising a fixed support for coupling to a compartment frame, and a mobile support for coupling to a door, wherein such mobile and fixed support are at least rotatably constrained one to the other. The hinge also comprises a coil spring operatively interposed between the fixed support and the mobile support to impose a predefined law of motion to the mobile support with respect to the fixed support, and an actuator for applying a push or a pull force onto said mobile support with respect to the fixed one.

5. Hinge comprising
a fixed support, a mobile support, said mobile and fixed support being at least rotatably constrained one to the other, an elastic means operatively interposed between said fixed support and said mobile support to impose a predefined law of motion to the mobile support with respect to the fixed support over the entire stroke of the mobile support with respect to the fixed support, wherein said fixed support comprises a frame housing the elastic means and to which a supporting element provided with a recess is fastened, a controlled motor means for applying a push or a pull force onto said mobile support with respect to said fixed support, and a motion guide bar articulated to said mobile support and coupled slidingly to said fixed support by means of a slider-crank system, said motion guide bar further slidingly engaging said recess, said slider-crank system comprising a slider that slides integral with said motion guide bar, wherein said supporting element acts as a countercheck for one end of said elastic member and said slider acts as a mobile support for the other end of said elastic member, wherein said motor means apply an axial push or pull force onto said motion guide bar via said slider in such a way that the motor performs a maximum of 20-30% of work during the first opening/closing step of the door, and the elastic means performs the remaining 70-90% of work.
