  • Bent blade screw ground anchor
    Patent number: 9133595
    Abstract: A ground anchor is provided for driving into the ground for anchoring or supporting a structure. The ground anchor includes a hub with a helical load bearing plate and a pointed ground engaging end having a body with a spade point blade extending axially from the body and the hub. The blade has first and second opposing spiral major faces and first and second transverse minor spiral faces that converge at a flat axial face to form the blade with a spiral configuration. The blade has a longitudinal dimension extending at an inclined angle with respect to a longitudinal center axis of the ground anchor so that the axial face of the blade is spaced outwardly from the center axis of the ground anchor. The leading edge of the spiral blade directs the soil to the leading edge of the helical plate of the ground anchor.
