ABSTRACT:
A simplified flat top umbrella includes: a central shaft (1) having an upper notch (11) formed on an upper portion of the shaft (1) and a lower runner (12) slidably held on the shaft (1), a top rib (2) pivotally secured to the upper notch (11), an outer rib (3) fixed to the top rib (2), a stretcher rib (4) pivotally connected between the lower runner (12) and the top rib (2), and a pulling rib (5) secured between the stretcher rib (4) and an outer portion (32) of the outer rib (3); whereby upon extending of the ribs having an umbrella cloth retained thereon for opening the umbrella, the top rib (2) and the outer rib (3) will be lifted to form a generally horizontal canopy and the outer portion (32) of the outer rib (3) will be pulled inwardly by the pulling rib (5) and the stretcher rib (4) to form a skirt portion generally perpendicular to the horizontal canopy, thereby providing a light compact flat top umbrella for a convenient carrying and operation.
