Patent ID: 8915686

Claim:
A unitary strike, drop-in anchor comprising: an anchor body, having a centrally located bore; the bore having an internally threaded portion at an outer end, the threaded portion having a substantially constant internal diameter, and an inner end portion having a narrower internal diameter and which is flarable; a slug held within the anchor body bore, adjacent the narrower internal diameter; a bolt having a driving head and a threaded shaft, threadedly connected into the threaded portion of the anchor body, and a centrally located bolt bore through the bolt driving head and shaft; a strike tool, comprising an externally extending shaft and an inner expanded end; the expanded end being located within the anchor body bore adjacent the slug, and the shaft extending outwardly from the expanded end through the bolt bore and out of the bolt head; the strike tool shaft intended to be driven by a hammer or other heavy object, and the inner expanded end of the strike tool being too large to pass through the bolt bore and is thus locked within the anchor bore when the bolt is threadedly connected into the anchor body; whereby striking the outer end of the strike tool shaft when the anchor is inserted into concrete pushes the slug into the narrower portion of the anchor bore, causing the inner end of the anchor to expand and become wedged within the concrete.
