Abstract:
1. A unique multi-adjustable, rotatable, and opposite-double-locking umbrella-stanchion-and-stand system for being used with crank-arm-operated collapsible umbrella canopy comprises: an umbrella-supporting post having two opposite post openings on its body; a cover plate; plate attaching means a stanchion cover hub molded to the center of the under surface of said cover plate; a plurality of bearing balls; a base, said base having a shape of a circular cup, said base having a circular bearing groove at its edge for said bearing balls to roll therein such that said umbrella-supporting post can be rotated; a base bearing slid on said stanchion cover hub; base attaching means for attaching said base to said cover plate, a plurality of radial teeth, said radial teeth molded to the circular corner of the inner surface of said base; a stabilizing foot for stabilizing said umbrella-supporting post; foot attaching means for attaching said stabilizing foot to said base; a U-shaped rotational lever having two opposite square lever openings at its two opposite ends; a U-shaped rotational actuator having a square actuator passage extending the width of its body; a lever attaching means comprising a square-cross-sectional in and pin attaching means for attaching said pin to said umbrella-supporting post and to said rotational lever after said pin is inserted through said two opposite post openings, through said two opposite square lever openings, and through said square actuator passage; a push rod; a rod attaching means for attaching said push rod to said rotational actuator; a U-shaped rotational foot; a foot attaching means for attaching said rotational foot to said push rod; two opposite L-shaped locking arms, each having a head and a tail, said cover plate having a plate passage for said rotational foot to pass through and rest on the tails of said locking arms; and two opposite arm attaching means for attaching said locking arms to the under surface of said cover plate at predetermined locations thereon such that the heads and tails of said two opposite locking arms can seesaw and such that the heads of said two opposite locking arms are pulled downward between said radial teeth by the gravitational force to lock said post in place, wherein, said rotational lever capable of being lifted upward to push the tails of said two opposite locking arms downward to raise the heads of said two opposite locking arms upward over said radial teeth to unlock said post to allow said post to rotate, wherein, said rotational lever capable of being lowered downward to push the tails of said two opposite locking arms upward to lower the heads of said two opposite locking arms downward between said radial teeth to lock said post to prevent said post from rotating, whereby the unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system is provided, which is operated with one finger, is simple and safe to operate, double-locks said post to prevent said post from warping, allows an operator to keep both feet on the ground while operating the system, eliminates any hazardous foot pedal protruding from said base, and eliminates personal injuries and provides safety to an operator.
