Abstract:
A safety umbrella runner comprising:a sleeve slidably engaged with a central shaft defining a longitudinal axis at a longitudinal center of said shaft; a ferrule integrally formed on said sleeve for pivotally securing a stretcher rib of a rib assembly on said ferrule; a retarding shoulder portion formed in said sleeve for engaging a protrusion of a spring catch resiliently fixed in the central shaft for retaining the runner when opening an umbrella; the improvement which comprises: a sliding push button including a plunger slidably engaged with a primary slot transversely formed through said runner, said primary slot formed in said runner defining a latitudinal axis at a center of said primary slot to be perpendicular to said longitudinal axis in said central shaft, said push button having an inside surface operatively contacted with said protrusion of said spring catch; whereby upon an inward depression of said push button to thrust said protrusion of said catch inwardly to disengage the retarding shoulder portion of said runner from said protrusion of said catch, said runner is not retarded by the catch and is lowered to close the umbrella; and said sliding push button including a pair of lugs symmetrically formed on opposite side walls of said plunger, said two lugs respectively slidably engaged with two secondary slots symmetrically formed in opposite side walls of said primary slot in said runner, and each said secondary slot being generally perpendicular to said longitudinal axis of said central shaft.
