ABSTRACT:
One form of conventional earth anchor device includes an anchor which is driven into the ground as the leading element of a combination. Thus, the anchor must be streamlined to facilitate ground entry which is incompatible with the need for a curved body facilitating anchoring. Another problem is the need for anchors having large bearing areas which require considerable effort for insertion into the ground. A device providing a solution to these problems includes a tube or sleeve with a sacrificial blade releasably mounted in the bottom end thereof for driving into the ground, and a rod carrying an anchor and a spring biasing the anchor outwardly, whereby the sleeve can be driven into the ground, following which the rod is held down while the sleeve is extracted, leaving the blade, and, when the anchor and spring exit the sleeve, the spring biases the anchor into a ground engaging position. An upward pull on the rod pivots the anchor into a secure anchoring position in the ground.
