Arrangement introduced in a helical sun umbrella with central structure ru00ecgida or similar

摘要

"Provision introduced in fixative helical sun umbrella with central structure ru00ecgida or similar.It is composed of a helical fixation element (1), obtained from a matedal elliptic ring (2) which revolutionizes the surface of a central axis (3),Interconnected by a lamellar surface (4) of adjacent helical revolution, made of single material, resulting in a unique body.The upper terminal of cylindrical fit male (5) is symmetrically.Two holes (6) for fixing and coupling in the lower portion of the support rod (7) of the umbrella (8); in the lower portion of the body elliptic ring (2) is built on a thin terminationThe sharp (9) for better penetration in the soil (10); the rigid central structure (4), gives the helical fastener (1), the mechanical strength of the torsion in the action to penetrate the soil by threading.Keeping the same attribute on the resistance to bending, relevant to the action of wind force, after the installation of the parasol (8), preventing plastic deformation to the material manufacturing industry.
