  • Ground anchor
    Patent number: 5613329
    Abstract: A ground anchor is shown for use in anchoring and supporting posts or other structures in the ground. The ground anchor includes a tubular socket and a twisted flat bar. The socket is provided with a structure to prevent rotation and has a diametral slot provided in a bottom closure of the socket. The socket is inserted into the ground by driving the bar into the ground, via the slot, so that it rotates and follows a helical path as dictated by the twist of the bar.
