Abstract:
A hinge for the controlled rotatable movement of a closing element, such as a door, a door leaf or the like, anchored to a stationary support structure, such as a wall, a floor, a frame or the like. The hinge comprises a hinge body and a pivot defining a first axis reciprocally coupled to allow the closing element to rotate between an open position and a closed position. The hinge further comprises a working chamber defining a second axis substantially perpendicular to said first axis and a plunger element sliding within the working chamber along the second axis between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The pivot includes a pinion member, whereas the plunger element includes a rack member engaged with the pinion member.
