Abstract
A ventilated umbrella includes a support frame forming a tetragonal surface, a first canopy secured on the tetragonal surface of the support frame and having an outer edge, a loop-shaped second canopy secured on the tetragonal surface of the support frame and having an inner edge located under the outer edge of the first canopy, a gap defined between the first canopy and the second canopy, and a plurality of elastic members each having a first end secured to the support frame, and a second end secured to the inner edge of the second canopy. In such a manner, the gap between the outer edge of the first canopy and the inner edge of the second canopy is increased by the drawing force of the elastic members, thereby enhancing the ventilation effect.
