A facility cover in the form of an extensible shed has movable arches that support a flexible canvas cover. The arches are modular and are connected in groups by diagonal elements hinged so as to form parallelograms with pantograph movement. The ends of the shed have at least one arch of reduced height so as to form an apse shape. Folding elements are provided on the sides of the shed that cooperate with the hinged parallelogram structure so as to assure that the cover folds outwardly in a bellows fashion as the arches are moved close to each other. As a result, the folding of the cover does not interfer with the movement of the arches.

A shed of the extensible type, having arches movable on rails and supporting a flexible cover, characterized in that: said arches are self-sustaining and are made up of modular elements, adjacent ones of said arches are connected together in a single group by means of diagonal elements hinged so as to form parallelograms with pantograph movement that keep the arches spaced and vertical during the opening and closing of the shed, said shed is opened with movement of the arches in a single direction and closed with movement in the opposite direction, one end of the shed is fixed to the ground and the other end is movable on rails as a carriage; the ends of the extensible shed each have at least one arch of lower height so as to form an apse shape that closes each of said ends, said lower arch is connected to the adjacent sliding arch by means of cross beams and by at least one transversal element placed along a chord of the lower arch substantially at the height of said hinged parallelograms, slanted rods are provided between the adjacent arch and the lower arch suitable for stiffening the arch complex and providing support for and fastening of the canvas at the end of the shed, said canvas is stretched between said lower arch and the ground; and folding means are fixed to each hinged parallelogram for acting horizontally on the canvas adjacent said parallelograms to fold the canvas in bellows fashion toward the outer side of the shed during the opening of the shed when the arches are approaching each other.
