- a further drawback of such hinge devices consists in the fact that the elastic and damping forces transmittable to the door are correlated and not independent.
- An object of the present invention is to propose a compact and dampened hinge device which can also be installed in household appliances and appliances having little space available for the hinge device itself.
- Another object is to propose a hinge device with a smooth and regular operation.
- a further object is to propose a hinge device in which the elastic forces can be decoupled from the rotation damping forces to act on the door with elastic forces independently from the damping of the rotation thereof.
