Proposed is a door hinge that includes an arm installed on a door, a housing installed in a main body of a mechanism provided with a door and connected to the arm by a hinge shaft, a damper casing connected to the arm inside the housing by the hinge shaft and having one surface supported by a support portion of the housing, a pair of main links connected to the arm inside the housing by a link shaft to linearly move, a main spring assembly including a spring lever and a main spring inserted into the spring lever, and a damper provided inside the damper casing and moving along the periphery of the arm.

A hinge for a swing closing element includes a hinge body and a third male or female connection element defining an axis that are coupled to each other to rotate with respect to each other between an open and a closed position. The hinge body includes a curvilinear guide slot defining an angular trajectory that lays on a plane substantially perpendicular to the defined axis. The third male or female connection element is engaged in the curvilinear guide slot so that upon the mutual rotation of the third male or female connection element and of the hinge body, the defined axis translates along the angular trajectory.
