More Information
Summary:A hollow, molded, cylindrical screw-threaded device for removably anchoring objects such as beach umbrellas, ropes, pet leashes, and the like into sand comprises a hollow cylinder with two fixed molded perpendicular winglike projections for its insertion. A thumbscrew in the side of the cylinder allows for grasping and release of objects inserted into the anchoring device. Screw threads which taper in diameter and depth successively as the tip is approached allow for easier insertion into compact deeper sand and also for firmer anchoring in looser surface sand. Beveled lower thread surfaces allow for easier insertion of the device and flat upper thread surfaces afford greater resistance against forcible removal of the device from the sand. Moveable loops of two alternate designs allow for pivoting attachment points for ropes, pet leashes, and the like.
