ABSTRACT:
An umbrella reversal prevention structure including a plurality of flexible guys having outer ends connected one each to different ones of the resilient ribs of the umbrella. The inner ends of the guys are connected to the shaft of the umbrella adjacent its outer end. The guys are provided with adjusting structure for adjusting the length thereof to provide a preselected tension in each guy for effectively preventing undesirable displacement of the resilient rib outer ends outwardly from the normal disposition thereof in the open bowed configuration of the umbrella, thereby to prevent reversal of the umbrella structure as from a high wind force directed outwardly thereagainst.
