Abstract
An improved wing-type ground anchor. The ground anchor includes a central body portion, wings radiating laterally from the body portion, and a leg portion at the front end of the body portion GROUND ANCHOR that operates like a star-point drill for penetrating the ground. The sides of the leg portion each include a plurality of sharpened leading side edges which are longitudinally offset from each other. Each of the wings also includes a plurality of sharpened leading side edges which are longitudinally offset with respect to each other. The offset leading side edges and wing edges progressively extend greater distances laterally outward from the body portion along the length of the leg portion and the wings. Since smaller side edges and wing edges are advanced first, the staged side and wing edges facilitate passage of the ground anchor through soil. The wings of the ground anchor also diminish in thickness and taper between the leading and trailing edges for reducing friction between the top and bottom wing surfaces and the soil. In combination, the staged side edges, staged wing edges, and tapered wings greatly reduce the driving force required to drive the ground anchor through …
