Abstract
Improved umbrella, characterized in that each of the rods of the supporting frame of the fabric, modifies its corrugated cross-section that generally presents, flattening a relatively short section in relation to the total length of the rod, this section being placed flattened by of the free end of the rod but remaining between the outer end thereof and the free end of the rod another section, also grooved, and whose length does not exceed approximately half of that of the section flattened, so that the open the umbrella, the tension that the fabric acquires forces each rod to pronounce its curvature in the aforementioned area of deformed section given to offer in that section a lower resistance to bending than the grooved rest, extending the path according to the mentioned grooved section of end that comes to be tangent to the curvature of the segment espoused at the outer end thereof.
