Lifting mechanism, e.g. for gastronomical washing machine cover, has lever arm with undulating surface that interacts with coupling body mounted on cover and guides coupling body

摘要

The mechanism has a vertically reciprocally movable closure device such as a cover of a washing machine or similar with a lever arm (23) joined to it so as to be rotatable and linearly movable. The lever arm has at least one undulating surface profile (28-30) that interacts with a coupling body (17) mounted on the cover (5) and guides the coupling body.
