ABSTRACT:
A spread position securing device for beach parasols includes a shank, a fixing base on an upper portion of the shank, and a runner fitted around slidably along the shank, plural ribs pivotally connected radially to the fixing base, and plural stretchers connected pivotally between the runner and intermediate portions of the ribs. Then the parasol can be spread from a collapsed position to a spread position. The feature of the invention is a cylindrical sleeve fixed in the runner and fitted around the shank to slide up and down so that the cylindrical sleeve may contact the fixing base to secure the contact points of the stretchers with the runners at a little higher position than the contact points of the stretchers with the ribs when the runner is pushed up to the spread position. Thus no other components are needed to secure the spread position of the parasol, convenient to handle.
