Ground anchor providing minimal ground disturbance
A ground anchor, including a body having an upper surface and a lower surface, ground piercing members depending from the lower surface of the body, the ground piercing members being adapted to engage an underlying ground surface and prevent movement of the body along such ground surface, ballast positioned on or in the body, the ballast being sufficient to maintain the ground piercing members engaged with the ground surface when under load, and means for securing an anchor line to the body.
1. A ground anchor, comprising:
a body having an upper surface and a lower surface;
ground piercing members in the form of rows of spaced-apart individual teeth rigidly fixed to and depending from the lower surface of the body;
at least one ground piercing blade member secured to and spanning between an upper portion of the teeth;
ballast positioned on or in the body; and
means for securing an anchor line to approximately a center of gravity of the body;
the teeth having an orientation relative to the at least one blade member which provides more resistance in a first direction perpendicular to the at least one blade member than in an opposed second direction.
2. The ground anchor as defined in claim 1 , wherein the ballast is integrally formed into the body.
3. The ground anchor as defined in claim 1 , wherein the ballast includes more than one weight, the more than one weight forming a stack on the upper surface of the body.
4. The ground anchor as defined in claim 1 , wherein the means for securing an anchor line to the body is an attachment ring.
5. The ground anchor as defined in claim 1 , wherein an arm is pivotally mounted to the body with the means for securing an anchor line to the body being positioned at a remote end of the arm.
6. The ground anchor as defined in claim 5 , wherein the arm is pivotally mounted at approximately the center of gravity of the body.
7. A ground anchor, comprising:
a body having an upper surface, a lower surface and a center of gravity;
ground piercing members in the form of rows of spaced-apart individual teeth rigidly fixed to and depending from the lower surface of the body;
at least one ground piercing blade member extending transversely across an upper portion of the teeth;
ballast positioned on or in the body, the ballast being a stack of weights positioned on the upper surface of the body;
an arm having an attachment end and a remote end, the attachment end being pivotally attached to the body at approximately the center of gravity;
the teeth having an orientation which provides more resistance in a direction perpendicular to the at least one blade member defined by the arm than in an opposed direction; and
an attachment ring at the remote end of the arm providing means for securing an anchor line to the body.
