US Patent 10265554 Rapid escape anchor

A self-righting rapid escape anchor including a shank and an integral hook, together forming front and rear sides, right and left sides, a lower end having a rope hole for passing a safety rope, a body slot in the shank, a saddle slot in the hook, and a tip holder at the terminal end of the hook for removably attaching a hardened steel piercing tip. The weight distribution of the tip in relation to the shank and hook induces rotation about the longitudinal axis of the anchor to place the anchor in a point down orientation when it is pulled longitudinally by a rope attached to the rope hole.
