Abstract (en)
[origin: WO2012012401A2] In an anchoring device, a drill head and expansion element(s) are configured to cooperatively interlock with each other to provide for directed movements of the drill head relative to a longitudinal axis of the shaft. Co-operating contact surfaces between the drill head and the expansion element(s) are configured such that relative longitudinal movement of the drill head with respect to the expansion element(s) displace(s) the expansion element(s) outwardly so the expansion element(s) can provide frictional contact with a borehole once inserted therein. A stop is configured to restrict or prevent longitudinal movement of the expansion element(s) upon relative longitudinal movement of the drill head with respect to the expansion element(s).
