Definitions

the present invention relates to a device for driving nails intended to be mounted on devices such as pneumatic guns or electric percussion puppets.
the invention relates to devices of the type comprising a tubular element intended to receive a nail and in which is movable a rod intended to be connected to an impact device.
US Patent 4,316,513 relates to a device intended to be used to drive nails into mine galleries.
the device according to this American patent comprises a housing intended to receive a nail and whose side wall is pierced with a radial hole in which is housed a permanent magnet.
Such a device can only be used with very specific cone-shaped nails, otherwise they would not be guided during driving. In addition, if ordinary nails were used, due to the position of the magnet, they would tend to be placed sideways so that one could not drive nails regularly. Finally, the surface to be nailed is not protected against impact.
One of the aims of the invention is to provide a device which overcomes the various drawbacks of the prior art.
the device according to the invention is of the type comprising an elongated body having, at one end, a tail intended to be fixed to the device and the other end of which is shaped to constitute a cylinder in which is movable, against the action a spring, a piston extended by a tube, said body comprising a rod passing axially through the cylinder and extending through the piston and a tube conduit, the free end of the tube comprising magnetic means for retaining the nail to driving, and is characterized in that the magnetic retaining means of the driving nail consist of a magnetic sleeve protected by a rubber cap whose free end projects beyond the free end of said magnetic sleeve.
the free end of the tube is integral with a sleeve having an axial hole aligned with the conduit of the tube, said sleeve, at its free end, being shaped to present a cavity intended to receive the magnetic sleeve and at its periphery a bead, while the cap has a groove intended to cooperate with said bead.
the end of the magnetic sleeve adjacent to the bottom of the cavity comprises a chamfer, said bottom having a corresponding chamfer.
the device shown in the figure comprises a body designated as a whole by the reference I and which is extended at one end by an axial shank 2 pierced with a tapped hole 3, while the other end is shaped to present a cylinder 14.
a threaded rod 4 which is extended by a rod 5 disposed axially in the cylinder 14.
the free end of the threaded rod has a slot 16 which allows the grip of a tool such as a screwdriver.
a locking screw 6 provided, for example, with a hexagon socket 28 to allow its screwing or unscrewing.
a frustoconical compression spring 7 which bears on the one hand, on the bottom of the cylinder 14, and, on the other hand, on a piston 8 movable in said cylinder and integral with a tube 9 in the duct 10 from which the rod 5 can slide.
the end of the body I opposite to that provided with the tail 2 has an external thread 29 on which is screwed a plug 12 having a bottom II pierced with a hole 13.
the hole 13 allows the free sliding of the tube 9, while the bottom II constitutes a stop for the piston 8.
a socket 30 which has a shoulder 17 abutting against said free end, said shoulder being pierced with a hole 21 aligned with the conduit 10.
the sleeve 30, at its free end, has a cavity 19 delimited by a shoulder 20 and in which is housed a sleeve 22 made of magnetic material to form a permanent magnet.
the sleeve 22 is preferably glued so as not to risk damaging it during assembly.
a rubber cap 24 which is shaped to present an internal groove 25 intended to cooperate with a peripheral bead 18 provided on the lateral surface of the sleeve 30.
the cap 24 is shaped so as to resiliently match a part of the sleeve 30 and the sleeve 22 and it has a length such that said sleeve 22 is fully protected, the free end being pierced with a hole 26 aligned with the conduit 10 and hole 21.
the end of the hole 21 opposite to that facing the side of the duct 10 may have a chamfer 27, a corresponding chamfer 23 being provided at the adjacent end of the sleeve 22.
the tail 2 When it is desired to drive a nail, the tail 2 is fixed either to a pneumatic gun or to the mandrel of an electric percussion chignole, the driving nail being engaged in the hole 26 and in the conduit of the sleeve 22 in which it is held magnetically.
the device is applied by the cap 24 to the surface to be nailed and the pneumatic gun or the chignole is operated at the same time as it exerts a pressure so as to move the piston 8 against the action of the spring 7 and thus do wear the free end of the rod 5 against the head of the nail so that the percussions of the pneumatic gun or the chignole reflected on the nail cause the latter to sink.
the chamfers 23 and 27 facilitate the installation of head nails and the ejection of these.
the cap 24 makes it possible, on the one hand, to protect the sleeve 22 which, necessarily, does not present a significant mechanical resistance, and, on the other hand, the part to be nailed.
