A hinge for a door anchored to a wall, the hinge including a fixed element coupled to the wall and a movable element coupled to the door. The fixed and movable elements rotate between an open position and a closed position about a first longitudinal axis. One of the movable and fixed elements includes cam means rotating about the first longitudinal axis, the other of the movable and fixed elements including follower means mutually interacting with the cam means for sliding along a second longitudinal axis substantially perpendicular to the first axis. The follower means includes an elastic counteracting element. The cam means includes a first cam element interacting with the follower means for movement from end-stroke positions to an intermediate position and vice-versa. The cam means further includes a second cam element interacting with the follower means for movement from the intermediate position to the end-stroke positions and vice-versa.

The hinge according to claim 1, wherein said at least one elastic counteracting element includes an elastomeric body. 3. The hinge according to claim wherein said elastomer is compact polyurethane. 4. The hinge according to claim 3, wherein said elastomer has a Shore A hardness of 50 ShA to 95 ShA. 5. The hinge according to claim 1, wherein said at least one interface element has a first end interacting with said at least one elastic counteracting element and a second end interacting with said at least one first cam element and with said at least one second cam element. 6. The hinge according to claim 1, wherein said at least one interface element includes a central elongated portion defining a third longitudinal axis parallel to said first axis and at least one end transverse appendix perpendicular to said first axis, said central elongated portion including said at least one first operating surface, said at least one end transverse appendix including said at least one second operating surface. 7. The hinge according to claim 6, wherein said pivot includes a cylindrical outer surface including at least one flat face defining said at least one second cam element. 8. The hinge according to claim 7, wherein said at least one second operating surface is planar, said cam member and said follower member being configured so that said at least one flat face and said at least one second operating surface are parallel and mutually contact engaged when the movable element is in a closed position and are perpendicular to each other and mutually spaced apart when the movable element is in an open position. 9. The hinge according to claim 8, wherein said pivot includes an elongated appendix transversely extending along said second axis to define said first cam element, said elongated appendix including a peripheral edge configured to contact engage the first operating surface of said interface element to progressively interact with said elastic counteracting element. 10. The hinge according to claim 9, wherein said elongate appendix defines a plane perpendicular to said at least one flat face of said second cam element. 11. The hinge according to claim 1, wherein said at least one elastic counteracting element is interposed between a first abutment wall and a second abutment wall, said at least one interface element having a first end defining said first abutment wall, wherein the hinge further comprises adjustment means for adjusting the preload of said at least one elastic counteracting element which include a slide sliding along said second axis having a first end defining said second abutment wall and a second end opposite thereto, said adjustment means further including at least one adjustment screw having a first active end configured to interact with the second end of said slide and a second operating end accessible from outside by a user to adjust the sliding of the slide along said second axis. 12. The hinge according to claim 11, wherein said hinge body comprises at least one connecting plate for coupling thereof to the stationary support structure or to the door, said at least one working chamber including said adjustment means, said at least one adjustment screw being transversely inserted within said at least one connecting plate to define a fourth axis perpendicular to both said first axis and said second axis. 13. The hinge according to claim 12, wherein said first active end of said at least one adjustment screw has a generally fustoconical shape to come into contact engagement with the second end of said slide, so that the penetration of said at least one adjustment screw along said fourth axis induces the sliding of said slide along said second axis towards said first abutment wall. 14. The hinge according to claim 13, wherein said adjustment means include at least one pair of adjusting screws spaced apart each other. 15. The hinge according to claim 14, wherein each of the adjusting screws of said pair selectively acts on different portions of said elastomeric body. 16.
