Structure consisting of fixed and movable elements, assuring their complete stability when in extreme positions, when extended, folded and in all positions in between, while also providing for the gathering of rainwater by means of the structure's metal framework. Each element comprises two vertical side sections (1a, 2a, 3a, 4a) consisting of a rectangular frame, closed in the case of the fixed element, open in the movable element, along one of its vertical ribs, constructed in such a way as to circumscribe the frame of the preceding element and to nest into that of the next, said frames, being in the same vertical plane passing from the runner on the ground, consisting of hollow upper beams (1d, 2d, 3d, 4d) and lower beams (1e, 2e, 3e, 4e), which allow the elements to be guided between them when being moved and rainwater to be collected and passed to ground level, said frames being interconnected by extendable cladding elements (15 and 16). |
