Abstract

The hinge for wings or doors, in particular of electrical appliances, comprises a first box-shaped body, a second box-shaped body, a connecting element between the first and second bodies, and a damper cylinder for applying on the second body an action damping its movement towards the first body.

Claims

1. A hinge, comprising:

a first box-shaped body for fixing to a frame;

a second box-shaped body for fixing to a door;

a connecting mechanism between the box -shaped bodies, for rendering the door movable with a tilting action relative to the frame between a closed position and at least one open position;

a damping mechanism, supported by the first body, for applying a damping force on the second body damping movement of the second body towards the first body, when the closed position is almost reached; and

a mechanism for controlling operation of the damping mechanism, the mechanism for controlling operation attached to the second box-shaped body, the mechanism for controlling operation spaced apart from the damping mechanism in a non-engaging manner when in the open position, the mechanism for controlling operation first coming into operative engagement with the damping mechanism only when the closed position is almost reached and from that position of first operative engagement until the closed position, operatively engaging the damping mechanism in such a manner that a compression of the damping mechanism continuously increases between the position of first operative engagement and the closed position;

a mechanism for operating the damping mechanism, the mechanism for operating the damping mechanism being operatively positioned between the mechanism for controlling operation and the damping mechanism;

wherein the mechanism for operating the damping mechanism comprises a rocker lever pivoting on the first box-shaped body.

2. The hinge according to claim 1, wherein the mechanism for controlling operation engages the rocker lever at the position of first operative engagement, causing the rocker lever to rotate about its own pivoting axis.

3. The hinge according to claim 2, wherein the rocker lever comprises a first arm for engaging the damper cylinder, and a second arm for engaging the mechanism for controlling operation.

4. The hinge according to claim 2, wherein the mechanism for controlling operation includes a peg projecting from the second box-shaped body.

5. The hinge according to claim 4, wherein the peg can move at least between a first, back non-operating configuration and a second, forward operating configuration.

6. The hinge according to claim 5, further comprising a device for moving the peg between its two configurations, back and forward.

7. The hinge according to claim 6, wherein the movement device comprises a slide having a cam profile designed to push the peg.

8. The hinge according to claim 7, wherein the movement device comprises a spring opposing the movement of the peg.

9. The hinge according to claim 2, wherein the mechanism for controlling operation includes a wall of the second box-shaped body.

10. The hinge according to claim 1, further comprising a plate for supporting the damper cylinder, the plate being fixed cantilever-style on the first box-shaped body.

11. An electrical appliance comprising at least one hinge according to claim 1.

12. The hinge according to claim 3, wherein the mechanism for controlling operation includes a peg projecting from the second box-shaped body.

13. The hinge according to claim 3, wherein the mechanism for controlling operation includes a wall of the second box-shaped body.
