Beschreibung
Zusammenfassung:	The mechanical elevating and revolving gates consist of a support box, an overlapping monolithic plate, lever mechanisms, and hinges. The overlapping plate is raised vertically upwards by a predetermined amount (up to 1 meter), after which the said plate is turned by 90 degrees, completely opening an aperture in the support box and forming a protective cover above the gates. These two movements are carried out by a single mechanism which transforms from a crank mechanism into a four-link chain mechanism and vice versa. Such transformation is possible due to two original hinges attaching the upper part of the overlapping plate to the support box. Such gates do not require locks and bolts. Even heavy snow accumulations will not prevent the gates from opening and closing.
