ABSTRACT:
A ground anchor for securing posts in the ground is provided. The ground anchor comprises a leg having a lower portion that is connected to a barb and an upper portion that is connected to a fin structure. The leg further comprises two sidewalls that meet at a corner and terminate at two diverging ends. The lower barb extends upward from the lower portion of the leg at a non-vertical angle. The barb provides additional resistance to any uplifting forces imposed upon the post or the anchor and further displaces or clears out soil from beneath the fin structure to facilitate the insertion of the post therethrough. The fin structure comprises a central crease portion disposed between two diverging fins. The fin structure is attached to the leg so that the central crease is disposed opposite to the corner of the leg. Each of the diverging fins are connected to one of the diverging ends of the sidewalls of the upper portion of the leg. A socket is formed between the crease and diverging fins of the fin structure and the corner and sidewalls of the leg structure. After the ground anchor is driven into the ground, the post is driven through the socket area. The soil or ground is then tamped around the post before a wedge is driven between the crease portion of the fin structure and the post. In addition to or instead of the barb structure, a rod connecting the lower end of the fin structure to the leg may be utilized to break up or displace the soil disposed underneath the socket as the ground anchor is driven into the ground.
