Abstract

For a vertically collapsible apparatus including an upper beam, such as lifting gantries, scaffoldings, . . . , a vertical upright or leg, normally used in pair, said leg comprising three elements pivoting on one another and on the beam by four axes of articulation (as known per se), wherein the four axes are parallel and perpendicular to the axis of the beam. The three elements are: a triangular element articulated by its apex on the beam at a distance of the end thereof, a trapezoidal element pivoting at the base of the first triangular element, and another triangular element having its apex articulated on the end of the beam and its base articulated on the trapezoidal element between the large and the small base thereof, whereby said apparatus can assume an operating and a transport position by a simple and practical manual operation.
