ABSTRACT:
A door hinge includes a first element, a second element and a lever connecting the first and second elements to each other. The lever is pivoted on the second element and has a first portion attached to the first element to make the first and the second element reciprocally mobile about a horizontal axis. The second element includes a box-shaped body housing elastic means acting in conjunction with a second portion of the lever to control the reciprocal motion of the first and the second element. The first element and the lever constitute a rocker lever pivoted on the second element and in which a first arm of the first element rotates in a plane outside the box-shaped body and parallel to the plane in which the second arm of the rocker lever lies.
