The actuating means are arranged in the device securing means and are directly controlled by the securing end of the pole and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The device actuating means comprise safety means arranged to avoid by gravity the control of the actuating means by the securing end of the pole when the spatial position of the pole is inappropriate. The invention also relates to an anchoring device provided with the same safety means.

  • Patent number: 8939341
    Abstract: A fastener driving apparatus includes a vacuum piston and a drive piston, which vacuum piston, when moved (by way of a motor and linear motion converter), draws a vacuum against the drive piston, which drive piston may be held in place by retention means. An anvil is coupled to the drive piston. The retention means is released electrically or mechanically at or near the point of maximum vacuum volume. This drive piston and anvil assembly is then driven by atmospheric pressure and may strike a fastener to drive it into a substrate. At least one position sensor may be used. Once the fastener is driven, the apparatus may reset to an initial position. At least one parasitic loss seal may be provided to reduce drag force on the drive piston, and a timed dwell may be provided for the vacuum piston for operation.
