Abstract
A hinge for doors of domestic appliances, comprising a first element and a second element pivoted to each other and movable relative to each other in tilting fashion, the first and second elements being fixable one to a frame and the other to a door of an electrical household appliance, for making the door movable with respect to the frame between a closed position and an open position, a lever for connection between the first and the second closing elements, an elastic element connected to the lever and designed to generate with its own deformation a force of elastic adjustment designed to compensate at least partially the weight force of the door during the opening or closing of the door, means for adjusting the intensity of the elastic reaction force.
Claims11
A hinge for a door of an electrical household appliance, comprising:
- a first element and a second element pivoted to each other and movable relative to each other in a tilting manner, said first and second elements being fixable one to a frame and the other to a door of an appliance, to make the door movable with respect to the frame between a closed position and an open position,
- a connecting lever connected between said first and second elements,
- an elastic element connected between said connecting lever and at least one of said first and second elements and capable of generating, by deformation of the elastic element, an elastic reaction force to compensate at least partially a weight force of the door during its-opening or closing of the door,
- an adjusting mechanism operatively connected with the elastic element and configured to adjust the deformation of the elastic element to adjust an intensity of said elastic reaction force, said adjusting mechanism including a cylindrical cam device configured to assume a first plurality of different configurations in correspondence of which said elastic element also assumes the first plurality of different deformed configurations,
- wherein said cylindrical cam device comprises a first lower cylindrical cam and a second upper cylindrical cam, said first lower and second upper cylindrical cams including respective profiles having a succession of inclined portions spaced by depressions, said first lower cylindrical cam and said second upper cylindrical cam being movable relative to one another to provide the first plurality of different configurations.
