Patent attributes
A pergola comprising a base module having a quadrangular support structure provided with vertical uprights connected to each other by at least one pair of rails and at least one transverse crossbeam connecting the pair of rails. The base module delimits a first roof surface. The pergola includes an extension module having a framework provided with at least one pair of struts. Each strut is at least partially vertically superposed on a corresponding rail, and is provided with at least one support leg that supports the overhanging framework on the side opposite the base module in the longitudinal direction. The extension module delimits a second roof surface at least partially superposed on the first. A guide structure is interposed between the struts and the rails for guiding a reciprocal longitudinal translation between the base module and the extension module, to modify the overall roof surface of the pergola.
