Abstract

A hinge for wings or doors, in particular for electrical household appliances, comprises a first element (2) and a second element (3) pivoted to each other and movable relative to each other in tilting fashion, a connecting lever (5) between the elements (2, 3), the lever (5) pivoting on the first element (2), the second element (3) being box-shaped and comprising inside it a spring (7) connected to the lever (5) by a drive rod (8) which can slide at least partly inside the second box-shaped element (3) itself.

Claims

1. A hinge for wings or doors, in particular for electrical household appliances, comprising a first element and a second element pivoted to each other and movable relative to each other in tilting fashion, a connecting lever between the first and the second element;

the lever pivoting on the first element;

the first and second elements being fixable one to a frame and the other to a door or wing, for moving the door or wing relative to the frame between a closed position and an open position, the second element being box-shaped and comprising inside it elastic means connected to the lever by a drive rod which can slide at least partly inside the second box-shaped element itself, the hinge further comprising friction means acting on the rod to slow the sliding movement relative to the second box-shaped element and guide means for guiding the movement of the drive rod along its axis of longitudinal extension.

2. The hinge according to claim 1, wherein the guide means comprise a roller which rollably engages with a wall of the second box-shaped element.

3. The hinge according to claim 2, wherein the roller is interposed between the lever and the second box-shaped element.

4. The hinge according to claim 3, wherein the roller has an axis of rotation which is fixed relative to the lever.

5. The hinge according to claim 4, wherein the roller is supported by the lever.

6. The hinge according to claim 1, wherein the friction means comprise a tapered friction element supported by the second box-shaped element and inside which the drive rod is slidably inserted, the tapered element engaging the rod on two opposite faces of it.

7. The hinge according to claim 1, wherein the friction means comprise an adjustable friction element operating on at least one face of the drive rod.

8. The hinge according to claim 7, wherein the adjustable friction element comprises a plug made of a material with a high friction coefficient and means for modifying the position of the plug relative to the drive rod.

9. The hinge according to claim 8, wherein the means for modifying the position of the plug relative to the drive rod comprise an adjustment screw.

10. The hinge according to claim 9, wherein the adjustment screw is accessible from the outside of the second, box-shaped element so it can be screwed and unscrewed.
