Abstract:
1. An opposition device for locking and/or braking a swing door of an electric appliance in which the door is movable about a horizontal rotation axis and along a predetermined trajectory, between at least two opposite, respectively open and closed, limit positions; the device comprising elastic means for at least partly counterbalancing the weight of the door along at least part of said predetermined trajectory, and being characterized by comprising: a contoured leaf spring fixable integrally to a casing of the appliance, in a fixed position close to the rotation axis of the door, the contoured leaf spring in turn comprising a first flexible arm projecting towards the door, and a second flexible arm projecting towards the door; a substantially rigid arm fixed integrally to the door, in a fixed position close to the rotation axis of the door, and projecting from the door towards the contoured leaf spring; said first flexible arm and second flexible arm of the contoured leaf spring, and said rigid arm of the door cooperating, in use, in sliding contact with one another along at least part of said predetermined trajectory of the door, so as to exert thrust on the door, at least close to said two opposite limit positions of the door, to oppose rotation of said door about said rotation axis.
