Abstract: The plug guide comprises a bore for receiving a nail comprising a head and a shaft onto which a skirt is slid, the bore having a passing section determined so that the head and the skirt of the nail cause it to be guided therein, a recess being provided in the front part of the plug guide for ejecting and expanding the guiding skirt. The recess comprises at least one radial bulge projecting inside, for extending the wall of the bore of the plug guide and forming a narrowing for guiding the nail. This invention further relates to a fastening device comprising the plug guide.

Abstract: The tool comprises an inner combustion engine, in a housing, for propelling a piston for driving a fastening member, a casing for receiving a fuel cell as a source of energy of the engine, a handle for handling the tool, with a trigger for actuating the tool and a casing for receiving a battery as the electrical supply source of the tool, the handle being connected to the housing of the engine, and extending substantially perpendicular to an axis of the housing. On the side opposed to the housing of the engine, the handle is connected to an arm for receiving the fuel cell and the electrical supply battery.

Abstract: The fastening apparatus for fastening elements includes a combustion chamber, a housing for a gas cartridge, means for injecting gas from a cartridge into the combustion chamber and a management module. An engine thermistor is provided to be subjected to the temperature of the chamber, as well as a second cartridge thermistor intended to be subjected to the temperature of the gas cartridge disposed in the cartridge housing. Both thermistors are mounted for transmitting their temperature information to the management module. The management module is operable for managing temperature information and determining the opening time of the injection means.

Abstract: The pole comprises a securing end, with tool securing means and tool 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 tool securing means to be directly controlled by the pole securing end and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The pole is well adapted to sealing guns.

Abstract: By means of the fastener fixing tool fitted with a fastener-guide (30), the base plate and the end (23) of the fastener-guide (30) are firmly fixed together, by a relative movement of the base plate and the end (23) of the fastener-guide (30), the one in relation to the other, in a plane perpendicular to the axis (21) of the fastener-guide (30), the base plate is pressed against a receiver-support (100) and attached there by means of a fastener. Where the base plate constitutes a female part for firmly uniting with the end (23) of the fastener-guide (30), the fastener-guide (30) is provided with an exterior annular groove (24) to receive a snap fit clamp (11) of the base plate.

Abstract: Fixing device using compressed gas, comprising a casing (1) containing a combustion chamber (17), a housing (4) for receiving a cartridge of compressed gas (5), a duct (19) for injecting compressed gas into the combustion chamber (17) from the cartridge (5), a magazine (3) for supplying fixing elements, a housing (6) for receiving a battery (7) for supplying electricity and a handle (8) connected directly to the casing (1) and substantially perpendicular to an axis (11) of the casing (1). The housing (4) for receiving the cartridge (5) extends substantially parallel to the handle (8) and is offset with respect thereto along the axis (11) of the casing (1).

Abstract: The device for fixing a plug in a support (100), with a piston (6) propelled by compressed gas, comprises a cylinder (5) in which the piston (6) is mounted, a combustion chamber (3), a combustion chamber sleeve (4) intended to close the chamber (3) at the rear with a cylinder head (2) and at the front with the piston (6) and the cylinder (5), a plug guide (8) acting as a probe for placing in abutment and for closing the combustion chamber (3). A pushing surface (30) and an abutment surface (29), which are respectively fixedly attached to the plug guide (8) and to the sleeve (4), are arranged to be fixedly attached to each other in a rearward translational movement when the plug guide (8) is placed into abutment, in order to close the combustion chamber (3), and to become detached from each other upon recoil of the device in reaction to firing in order to ensure that the plug guide (8) is kept in abutment against the support (100).
