ABSTRACT:
An umbrella frame having two collapsibly protractable structures defining ear-like projections. The umbrella frame has a plurality of ribs and associated pivotally attached struts extendable to define a characteristic dome shaped umbrella. The struts are further attached to a runner axially slidable on a central shaft of the umbrella that causes the outward extension of the struts to push the ribs outwardly when the runner is upwardly moved. In addition, two pairs of braces are respectively pivotally attached on one end to opposing struts either at the same point or at separate locations thereon, and extend through respective guide brackets fixedly attached to respective outer ribs. The other ends of the braces extend beyond the outer dome of the umbrella and are pivotally attached to a swivel coupling that causes loop shaped bending of the braces to define outwardly projecting ears from the characteristic dome shaped umbrella when the struts are extended by upwardly moving the runner.
