Abstract: The pole comprises a securing end, with device securing means and the device actuating means, a gripping end to be gripped by an operator and telecontrolling means for telecontrolling the actuating means. 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.

Abstract: An indirect fire device for fixing fasteners in a substrate material includes a piston for driving a fastener movably mounted in a barrel and a plug guide for guiding a fastener towards the substrate material. The device is adapted to receive a magazine for receiving a strip of fasteners in order to introduce the fasteners one by one into the plug guide. Each fastener is held in a sleeve comprising bridges for connection to another sleeve. The plug guide of the device includes a zone having an enlarged circular section at the opening of the magazine leading into the plug guide, extending axially over the length of a sleeve increased by the stroke of the plug guide for loading the device.

Abstract: A fixing tool including a nose adapted to receive, on the one hand, a fixing element from a fixing element magazine fixed to the nose and, on the other hand, a fixing element driving piston, propelled by an energy source, a sensor for operating the tool being arranged on the nose, wherein the sensor includes a flexible blade arranged on a biasing pad.

Abstract: The tool comprises an assembly of a tip-guide and a shear unit, on which can be fastened a charger of fastening elements. The fastening elements are introduced in the bore of the tip-guide through a passing window provided in the shear unit. The tool comprises a pivoting flap for adjusting the effective length of the passing window to the length of the fastening elements to be driven. The flap is pivotally mounted about an axis substantially parallel to the tip-guide bore and is adapted to provide a guiding surface for the shortest fastening elements before they enter the partially plugged passing window. With the invention, the short elements can neither rock the tool nor jam it.

Abstract: The indirect fire device for fixing fasteners (13) in a substrate material of the invention comprises a piston for driving a fastener (13) movably mounted in a barrel and a plug guide (11) for guiding a fastener (13) towards the substrate material. The device is adapted to receive a magazine (19) for receiving a strip (14) of fasteners (13) in order to introduce the fasteners (13) one by one into the plug guide (11). Each fastener (13) is held in a sleeve comprising bridges (16) for connection to another sleeve (15). The plug guide (11) of the device includes a zone having an enlarged circular section (21) at the opening of the magazine (19) leading into the plug guide (11), extending axially over the length (h) of a sleeve (15) increased by the stroke of the plug guide (11) for loading the device (L-L?).

Abstract: A connection arrangement for transferring gas from a compressed gas cartridge, has a valve element configured to control the release of gas from the cartridge; a male outlet which is integral with the valve element; a male inlet of a gas receiver for a tool that runs on compressed gas; and a connector receiving and connecting the male inlet and outlet. The connector is a tubular housing having a through hole extending from one end to the other. An inner wall of the housing contacts side surfaces of the male outlet and inlet in a sealing manner. The connector also has, in a middle region, transverse sealing surfaces that contact the end faces of the male outlet and inlet. The diameter of the through hole in this middle region is the same as the inner diameters of the openings in the ends of the male inlet and outlet.

Abstract: Apparatus for driving fasteners includes a barrel, a fastener guide which retreats as the apparatus is pressed against a substrate, a feed magazine, receiving a loader of fasteners, and a safety element configured to allow a fastener to be driven only after the fastener guide has retreated. There is a safety shoe configured to, when there is no fastener in the barrel, be moved into a safe position and prevent the retreat of the fastener guide, and including a tell-tale of the safe position of the safety shoe.

Abstract: Compressed gas canister (1?) intended to supply gas to a fastening appliance (2) that runs on compressed gas, includes a protective edge (12) forming a bowl inside which an ejection valve (16) having a bearing and displacement surface (26) is mounted so that it can move in translation between a position of rest and a gas-ejection position. The ejection valve (16) is mounted, inside a seal (3?), set back from the edge (15) of the bowl. The bearing surface (26) of the valve (16) does not protrude beyond the edge (15) of the bowl in the position of rest and is set back from the surface (30) facing towards the outside of the seal (3?, 23) in the gas-ejection position.
