Abstract:

An umbrella having uniquely designed and located vents for the protection of its structural components when used in open spaces where winds of medium and high velocities are encountered. The vents comprise pivotal flaps fabricated of semi rigid material and resiliently seamed to the ribs being caused to open due to air pressure exerted against the underside of the umbrella sufficient to cause the ribs to flex in the normal manner under such conditions. The vent attachments to the ribs are located at a distance from the peak of the umbrella near the swinging connections of the ribs and struts whereby pressure on both components may be relieved at these critical points.
