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.
  • Document FR-A-2 291 001 shows a device for planting nails adaptable to an apparatus such as a pneumatic gun or an electric percussion chignole and of the type comprising an elongated body having, at one end, a tail intended be fixed to the percussion device and the other end of which is shaped to form a cylinder in which is movable against the action of a spring a piston extended by a tube, said body comprising a rod axially passing through the cylinder and s extending through the piston and the tube conduit, the free end of the tube comprising means for retaining the nail to be driven, protected by a rubber cap whose free end extends beyond the free end of said tube.
  • the object of the present invention is to provide a device of the type which has just been described, provided with a simple and effective retaining member, in which both the permanent magnet and the surface to be nailed are completely protected, the free end of the tube being integral with a sleeve having an axial hole aligned with the tube conduit, said sleeve, at its free end, being shaped to present a cavity intended to receive the magnetic sleeve and at its periphery a bead stretched that the cap comprises 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, which facilitates the positioning and ejection of head nails.
  • the device shown in the figure comprises a body designated as a whole by the reference 1 and which is extended at one end, by an axial tail 2 pierced with a tapped hole 3, while the other end is shaped to present a cylinder 14.
  • a threaded rod 4 is screwed which is extended by a rod 5 disposed axially in the cylinder.
  • the free end of the threaded rod has a slot 16 which allows the taking of a screwdriver, in the tapped hole 3 is also screwed a locking screw 6 provided, for example with a hexagon socket 28 to allow its screwing or his unscrewing.
  • a thrust compression spring 7 which takes support 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 sliding on the rod 5 through its conduit 10.
  • the end of the body 1 opposite the tail 2 has an external thread 29 on which a plug 12 is screwed having a bottom 11 pierced with a hole 13 which allows the free sliding of the tube 9, while the bottom 11 constitutes a stop for 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 socket 30 has a cavity 19 delimited by a shoulder 20 and in which is housed a sleeve 22 of magnetic material to form a permanent magnet.
  • a rubber cap 24 which is shaped to present an internal groove 25 intended to cooperate with the peripheral bead 18 provided on the surface of the sleeve 30.
  • the cap 24 is shaped so as to partially match the sleeve 30 and the sleeve 22 protruding therefrom to better protect it, the end being pierced with a hole aligned with the conduit 10 and the hole 21, the cap also protecting the part to be nailed.
  • the end of the conduit 10 opposite to that facing the side of the hole 21 may have a chamfer 27, a corresponding chamfer 23 being provided at the adjacent end of the sleeve 22.
  • the cap 24 has a double function, it protects the sleeve 22 from shocks and the part to be nailed.
  • the opposite chamfers 23 and 27 facilitate the installation of the nails and the ejection of these.
  • the frusto-conical spring 7 by its turns returning to one another allows greater compression giving more advantage this stroke to the piston 8.

1. Vorrichtung zum Setzen von Nägeln, auf einen pneumatischen oder elektrischen Schußapparat aufsetzbar, von der Art, daß sie einen länglichen Körper 1 enthält, der an einem Ende einen Schwanz (2) zur Befestigung am Schlagapparat aufweist und dessen anderes Ende einen Zylinder (14) bildet, in dem sich ein durch ein Rohr (9) verlängerter Kolben (8) gegen eine Feder (7) bewegt, wobei besagter Körper 1 eine Stange (5) umfaßt, die am Schwanz (2) befestigt ist, die Achse des Zylinders (14) durchquert und weiter den Kolben (8) und den Lauf (10) des Rohrs (9) durchläuft. Das freie Ende des Rohrs (9) ist durch eine Gummikappe (24) geschützt, deren freies Ende das freie Ende besagter Muffe (22) überragt; dadurch gekennzeichnet, daß der einzuschlagende Nagel mittels magnetischer Wirkung festgehalten wird, die am freien Ende des Rohrs (9) angebracht und durch die Kappe (24) geschützt sind. Besagte magnetische Mittel werden durch einen Dauermagneten in Form einer Muffe (22) gebildet. Das freie Ende des Rohrs (9) ist fest mit einer ein in ihrer Achse liegendes Loch (21) aufweisenden Hülse (30) verbunden, die mit dem Lauf (10) des Rohrs (9) in einer Reihe liegt, wobei besagte Hülse an ihrem Ende so geformt ist, daß sie eine Höhlung (19) zur Aufnahme der Muffe (22) und auf dem Umfang einen Wulst (18) aufweist, während die Kappe (24) eine Rille (25) hat, in die besagter Wulst sich einpaßt.
2. Vorrichtung zum Setzen von Nägeln gemäß Anspruch 1, dadurch gekennzeichnet, daß das dem Boden der Höhlung (19) benachbarte Ende der Magnetmuffe (19) eine entsprechende Abfasung (27) aufweist.
3. Vorrichtung zum Setzen von Nägeln gemäß Anspruch 1, dadurch gekennzeichnet, daß die Stange (5) ein Gewinde (4) aufweist, das der Gewindebohrung (3) im Schwanz (2) entspricht, sowie eine in die Gewindebohrung (3) eingeschraubte Blockierschraube (6).
4. Vorrichtung zum Setzen von Nägeln gemäß Anspruch 1, dadurch gekennzeichnet, daß die Feder (7) konisch ist, was einem besseren Zusammenwirken mit dem Kolben (8) dient.
