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.
Claims12
A hinges system (10) comprising:
- a first hinge (12) and a second hinge (14), each of the first and second hinges (12, 14) being fixed at a part to a fixed system F and at the other part to a wing B;
- a cam mechanism for an automatic closing of the wing B once the wing B has been opened and released;
- and
- a fluid-operated device adapted to move a fluid from a first chamber (132) to a second chamber (134) and vice versa, through rotational motion of the wing B in order to control the closing speed of the wing B,
- wherein the first hinge (12) comprises a cam mechanism and the second hinge (14) comprises a fluid-operated device,
- wherein the first hinge (12) comprises a fixed part (30), fixed to the fixed system F, and a movable part (32), fixed to the wing B;
- the movable part (32) being rotating and translating with respect to the fixed part (30), and
- wherein the fixed part (30) comprises a first fixed body (34) which is fixed to the fixed system F and to which a first shaft (42) is rigidly coupled and a first roller (52) is rotatably coupled;
- and wherein the movable part (32) comprises a first rotating body (60) in which a first hole (66) is obtained and which comprises a first ramp (78);
- the first shaft (42) being received in the first hole (66) so that the first rotating body (60) is rotatable around the first shaft (42);
- the first roller (52) being in abutment and adapted to roll on the first ramp (78), so that in the rotational motion of the first rotating body (60) with respect to the first fixed body (34), the first rotating body (60) is also forced to translate in the direction of development of the first shaft (42).

- wherein the first hinge (12) comprises a cam mechanism and the second hinge (14) comprises a fluid-operated device,
- wherein the second hinge (14) comprises a fixed piece (16), fixed to the fixed system F, and a movable piece (18), fixed to the wing B;
- the movable piece (18) being rotating and translating with respect to the fixed piece (16), and
- wherein the fixed piece (16) comprises a second fixed body (80) which is fixed to the fixed system F and to which a second shaft (88) is rigidly coupled, a piston (100) being fixed to the free end of the second shaft (88);
- and wherein the movable piece (18) comprises a second rotating body (108) in which a second hole (110) is obtained and receives a gasket (124);
- the second shaft (88) being received in the second hole (110) so as to obtain a closed volume which the piston (100) divides into a first chamber (132) and a second chamber (134), the two chambers being communicating with each other through a conduit (126), so that in the translational motion of the movable piece (18) with respect to the fixed piece (16), a fluid contained in the first chamber (132) and in the second chamber (134) passes from the first chamber (132) to the second chamber (134) or from the second chamber (134) to the first chamber (132).
