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). Between the body of the square-shaped hub (16) and the attachment hinge body (22), adjustment means (26, 27, 29, 30, 33) are provided to adjust within a pre-established adjustment range the angular position of said hinge attachment member around the longitudinal axis of said attachment bar of the extendable device for the wind up tent.
