Abstract: A hinges structure (10) includes a first hinge (12) and a second hinge (14), each of them being fixed at a part to a fixed system F and at the other part to a wing B. The hinges structure (10) includes a cam mechanism for an automatic closing of the wing B and a fluid-operated device adapted to move a fluid from a first chamber to a second chamber through the rotational motion of the wing B. The speed of displacement of the fluid may be conveniently adjusted through a valve and consequently, the closing speed of the wing may be controlled.
