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: The housing is intended to receive a source introduced by means of its head and pushed into a position ensuring good transmission of energy. The housing includes a mechanism for converting a transverse movement towards the interior of the housing imparted by a pusher element of the mechanism accessible from the exterior of the housing into an orthogonal movement for ejection of the source.

Abstract: In the assembly of the invention, the assembly includes adapter means designed to connect the transmission member and the energy source and to ensure good transmission of energy between them. The adapter means comprise means for locking the energy source in rotation in the device and means for the angular indexing of the source in the position in which it is locked in rotation in the device. The invention is very suitable for gas fastening devices.

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: In the apparatus, a fastening element is driven into a support under the action of the gases from an explosive charge via a piston (2) that can move in a gun between a firing position and a fastening position, and a plug guide (5) in which a piston-braking ball (6) mechanism is mounted, which comprises arms (7) mounted to pivot on the plug-guide (5) arranged to modulate the radial force of the balls (6), depending on the relative displacement of the gun (3) and of the piston (2), between a maximum force when the piston (2) moves forward in the gun, and a non-zero minimum force, when the piston (2) moves back.

Abstract: A staple (4) for a delicate material (22) comprises two flexible legs (46, 47) between a head portion (56) connecting the legs and an introduction end portion (57). Between the head and end portions is located a discontinuity portion (58) so that when the staple is pushed into the material (22), at least one of the legs (46, 47) inclines with respect to the head portion (45) and thus ensures good resistance to extraction. The two legs (46, 47) are bent (76, 77) inwardly in the discontinuity portion (58) of the whole assembly to diverge from one another upon fixing the staple to the delicate material.

Abstract: The apparatus comprises along the riser (10) a return chamber with a front space (30) and a rear space (22) adapted to communicate with the combustion chamber (15) following a first displacement of the riser (10). Once the two spaces (30, 22) have been brought into communication with one another, they are separated from one another and the riser (10) is returned towards the rear in the barrel (9). The two spaces (30) and (22) communicate with one another during the displacement of the riser (10) and the rear space (22) is separated from, the front space (30) following a second forward displacement of the riser (10). As the rear space (22) communicates with the exterior of the apparatus, the expansion of the combustion gases trapped in the front space (30) then returns the riser (10) towards the rear into the firing position.The apparatus serves to fix components to a support material.
