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: The apparatus is intended to drive fasteners (21) for fastening a piece (20) to a support (30). The apparatus has a snout (12) equipped with a bearing shoe (14). The shoe is equipped with lateral positioning one-piece plate (15) on which there are formed a number of distinct lateral bearing surfaces (8, 8?, 8?, 8 82, 83) roughly parallel to the axis of the snout to be applied in particular to an edge of one of the pieces either the support piece or the piece that is to be fastened.

An information label is disposed astride the intersection of the first and second sides and on the two adjacent sides.

Abstract: The dowel's expansion bushing (2) is placed around a threaded rod (9) inserted in the bushing's (2) expansion core (3), between the strut (8) and the core (3). The bushing (2) includes a section (16) compressible along its centerline, which includes a shearing system (24) placed such that, after shearing, the bushing (2) is shortened along its centerline. The bushing also includes, on its section (25) next to the strut (8), coupling and axial holding spurs (50). The bushing (2) is composed of a cut sheet metal blank, rolled on itself, except for the part with the spurs (50).

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.

Abstract: The sealing apparatus (100) is used in a substantially vertical position by the user, who inserts a magazine pack containing nails into the hopper (101). After unlocking of the hopper (101), the nails slide in the flexible feed tube (10) as far as the front of a feeder for indirect firing, in a buffer guide (102). The user then merely has to actuate a trigger (103) in order to entrain the nails into the support via the feeder. In order to preserve the transparent quality of the tube (10), its effective inner cross section (21) is not circular, but is arranged (23) such that the contact between the lateral wall of the circular head of the nail (1) and the effective inner wall (21) of the tube (10) is not possible on certain portions (22) of the effective inner wall (21).

Abstract: In the apparatus, under the action of the explosion of a mixture of air and gas in a chamber closed by a chamber sleeve tube and a cage when the apparatus is pressed against something, a piston is propelled in a cylinder to drive an element. The chamber sleeve tube and the cylinder are arranged in such a way that, as the apparatus is closed, the chamber sleeve tube comes into abutment against the cylinder. The invention can well be applied to nail guns and other staplers.

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

Abstract: A device for securing a plug, of the type involving a piston (9) propelled by gas, has a combustion chamber (5) delimited on one side by the piston and on the other side by a cylinder head (7) with a duct (19) for injecting combustible gas open via one end (19A) into the chamber. The duct (19) has an orifice for creating a pressure drop between the part of the duct (19) upstream of the end (19A) and the chamber (5) itself, so as to at least partially avoid the vaporizing of the combustible gas in the part of the duct upstream of the end.

Abstract: The expanding sleeve (1) of the anchor has an interior bore (13) and an expander plug (15) which are conical, with roughly the same cone angle, and designed so as, through the wedge effect caused by the plug (15) being driven into the sleeve (1) to cause it to expand. The sleeve (1) has, at its periphery, an annular weakening groove (9) intended, during expansion, to shorten its axial expansion length.
