Abstract: A pavilion is comprised of a plurality of spaced, generally parallel frames, each having elongated modular elements connected one to the other by joints. Adjustable spacers are provided to connect the frames one to the other. Each modular element includes a pair of channels along opposite sides thereof for receiving enlarged margins of internal and external canvases, respectively, extending between the modular elements of adjacent frames. The spacers are adjusted to tension the canvases between the frames. Each modular element has a spigot as its central core to ensure rigidity. The modular elements are secured at their ends to joints which have channels forming continuations of the channels of the elements whereby the canvases may be drawn through the channels. The pavilion is thus extendable by the additional of further frames and canvases and readily and easily knocked down for transport.

Abstract: A projecting structure (1) with at least two articulated stretching arms (17, 18) which can be adjustably tilted, for wind up tents, particularly sunshade tents, comprising an attachment or supporting bar (2) secured to the wall through adjustable brackets (3), a roller (13) for winding up the tent sheet (T), with a respective control winch (14), said roller being supported on the bar (2) parallel thereto between end supports (15) keyed and secured to the ends of said bar, said bar having slidably mounted thereon square-shaped support and articulation hubs (16), one for each of said articulated arms which stretch the tent sheet (T). The structure is characterized in that each of said square-shaped hubs (16) comprises an attachment hinge body (22) which is hinged, on one hand, to said hub co-axially with the square-shaped bar mounted therein and, on the other hand, to the carrier arm (17) of the respective pivoted stretching arm (17, 18) around an associated pivot (25).
