Abstract

A door or wing for electrical household appliances comprises a pivoting element (30) and two hinges (40, 50) mounted along one perimetric side of the pivoting element (30) to join the pivoting element (30) to a frame (2) and make it movable relative to the latter between a closed position and an open position, each of the two hinges (40, 50) comprising a first member and a second, box-shaped member and a lever for connecting the first and second members.

Claims

1. A door or wing for electrical household appliances, comprising a pivoting element (30) and two hinges (40, 50) mounted along one perimetric side of the pivoting element (30) to join the pivoting element (30) to a frame (2) and make it movable relative to the frame (2) between a closed position and an open position, each of the two hinges (40, 50) comprising a first box-shaped member (5) and a second box-shaped member (6), a lever (7) for connecting the first and second members (5, 6), the lever (7) being pivoted to the second member (6) by means of a pin (10) to make the first and second members (5, 6) tiltable relative to each other;

one of either the first or the second member (5, 6) being attachable to the frame (2) and the other to the pivoting element (30), the door or wing being characterized in that only one (40) of the two hinges (40, 50) comprises elastic means (13), mounted on the second, box-shaped member (6) and designed to balance the pivoting element (30) as it moves between its two open and closed positions, the other (50) of the hinges (40, 50) not having such elastic means.

2. The door or wing according to claim 1, wherein the hinge (50) without the elastic means comprises limit stop means (10, 24) for determining a position of maximum angular opening of the second, box-shaped member (6) relative to the first member (5).

3. The door or wing according to claim 2, where the hinge (40) equipped with the elastic means (13) comprises a link rod (11) mounted on the second, box-shaped member (6) and pivoted on the connecting lever (7), the action of the elastic means (13) being applied between the link rod (11) and the second, box-shaped member (6), wherein even the hinge (50) without the elastic means comprises a respective link rod (11).

4. The door or wing according to claim 3, wherein the limit stop means comprise a portion (24) of the link rod (11), the portion (24) being designed to abut and engage the pin (10).

5. The door or wing according to claim 3, wherein the hinge (50) without the elastic means comprises means (23) for guiding the link rod (11) relative to the second, box-shaped member (6).

6. The door or wing according to claim 5, wherein the guide means (23) comprise a pin (22) integral with one of either the link rod (11) or the second, box-shaped member (6), and at least one slot (21) made on the other of either the link rod (11) or the second, box-shaped member (6).

7. An electrical household appliance comprising a door or wing (3) according to claim 1.
