IMPROVED ROTOTRANSLATION MECHANISM OF A SHUTTER OF A CONTAINMENT ELEMENT
A rototranslation mechanism of at least one shutter (102) in a containment element (103) wherein, between the at least one shutter (102) and a portion of the containment element (103)., at least three connection elements (11, 33, 34) are arranged pivoted at their ends, the at least one shutter (102) being movable in a rototranslating manner between a closed position of the containment element (103) flush with lateral walls (101) of such element (103), wherein the rototranslation mechanism (10, 30) is entirely housed in the containment element (103), and an open position in which the at least one shutter (102) is in a parallel and lateral position such to completely free the opening of the containment element (103).
