ABSTRACT:
An expansible anchor is adapted for inserting into a hole formed with a structure. The anchor includes a load cable and a first chock attached to an end of the load cable. A second chock resides adjacent to the first chock, and is adapted for movement between an anchor-contracting position and an anchor-expanding position. In the anchor-contracting position, the anchor is readily inserted into and removed from the hole of the structure. In the anchor-expanding position, the anchor is locked inside the hole of the structure. A chock-release column bears against at least one of the first and second chocks and has an enlarged head adapted for locating outside of the hole. The enlarged head defines a striking surface adapted for receiving a sudden force. This force is transferred through the chock-release column to the first or second chocks, such that the second chock is movable from the anchor-expanding position to the anchor-contracting position to thereby dislodge the anchor from the hole of the structure.
