Abstract

Described is a hinge for wings or doors, in particular for electrical household appliances, comprising a first body (5), a second body (6) and a connecting lever (7) between the first and the second body (5, 6).

Claims

1. A hinge for a door of a household appliance, comprising:

a first body,

a second body having a pivot pin with an axis, and

a connecting lever between the bodies;

the lever pivoting on the second body via the pivot pin about the axis and having a first portion integral with the first body for making the first and second bodies movable relative to one another with a tilting action;

one of the first and second bodies being fixable to a frame and the other to the door, for moving the door relative to the frame between a closed position and an open position;

the second body comprising;

a first substantially box-shaped element containing an elastic mechanism interposed between the second body and the lever for applying an elastic action on the lever;

a second box-shaped element positioned outside the first box-shaped element and slidably mobile relative to the first box-shaped element; and

an actuator mechanism for imparting a relative sliding movement to the first and second box-shaped elements;

wherein, the sliding movement of the first and second box-shaped elements relative to each other causes the first body to move away relative to the second body from a first position to a second position so that a distance between a distal end of the second box-shaped element and the axis of the pivot pin, about which the lever rotates, varies between a minimal value, in the first position, to a maximum value, in the second position.

2. The hinge according to claim 1, wherein the actuator mechanism comprises at least one rotating element pivoting on the first box-shaped element.

3. The hinge according to claim 2, wherein the rotating element comprises a first pin engaging a rod for driving the elastic mechanism and a second pin for engaging the second box-shaped element.

4. The hinge according to claim 1, wherein the second box-shaped element is integrated in the door.

5. The hinge according to claim 1, comprising at least one spacer element for the box-shaped elements.

6. The hinge according to claim 5, wherein the at least one spacer element is integrated in one of the box-shaped elements.

7. The hinge according to claim 5, wherein the at least one spacer element is removable and made of material with a low coefficient of friction.

8. The hinge according to claim 1, and further comprising the household appliance, the hinge being attached to the household appliance.

9. A hinge for a door of a household appliance, comprising:

a first body,

a second body having a pivot pin, and

a connecting lever between the bodies;

the lever pivoting on the second body via the pivot pin and having a first portion integral with the first body for making the first and second bodies movable relative to one another with a tilting action;

one of the first and second bodies being fixable to a frame and the other to the door, for moving the door relative to the frame between a closed position and an open position;

the second body comprising;

a first substantially box-shaped element containing an elastic mechanism interposed between the second body and the lever for applying an elastic action on the lever;

a second box-shaped element positioned outside the first box-shaped element and slidably mobile relative to the first box-shaped element; and

an actuator mechanism for imparting a relative sliding movement to the first and second box-shaped elements;

wherein the actuator mechanism comprises at least one rotating element pivoting on the first box-shaped element;

wherein the rotating element comprises a first pin engaging a rod for driving the elastic mechanism and a second pin for engaging the second box-shaped element.

10. The hinge according to claim 9, wherein the second box-shaped element is integrated in the door.

11. The hinge according to claim 9, comprising at least one spacer element for the box-shaped elements.

12. The hinge according to claim 11, wherein the at least one spacer element is integrated in one of the box-shaped elements.

13. The hinge according to claim 11, wherein the at least one spacer element is removable and made of material with a low coefficient of friction.

14. The hinge according to claim 9, and further comprising the household appliance, the hinge being attached to the household appliance.
