Definitions

  • the present invention relates to a rifle grenade intended to be launched by means of a rifle or the like, preferably with the aid of a conventional bullet cartridge.
  • Projectiles such as grenades, have been proposed which can be launched with a rifle. These projectiles generally comprise a head containing an explosive charge, this head being extended by a tubular tail intended to be threaded around the barrel of a rifle, most often equipped for this purpose with a blunderbuss.
  • the present invention aims to overcome these disadvantages by providing a particularly simple, economical and effective solution to the above problems.
  • a rifle grenade according to the invention of the type with axial bore is characterized in that in this bore is arranged a bullet pass made of a material whose hardness is between about 30 Shore A and about 70 Shore D .
  • Such a bullet offers the particularity of being easily crossed by the bullet while closing behind it to prohibit practically any passage to the propellant gases.
  • the grenade illustrated in FIG. 1 has a head 1 containing an explosive charge 2 equipped with any suitable firing means, for example a tubular rocket 3.
  • the head 1 In its rear part, the head 1 is extended by a tubular tail 4 with a tail unit 5.
  • the bore 6 of the tail 4 makes it possible to receive the end of the barrel of a rifle, end generally constituted by a launching blunderbolt.
  • the bore 6 is extended by a bore 7, passing axially through the head 1, this bore having a diameter slightly greater than the caliber of the rifle used for launching.
  • a ball pass 8 made of a flexible, respectively elastic material, is disposed in the bore 6, preferably against a shoulder 9 provided for this purpose. effect for example at the junction of bores 6 and 7.
  • the passage of the bale through such a pass-through practically does not cause any disappearance of material, either by tearing off or by fusion or combustion, provided that said pass-through conforms exit that it can expand sufficiently during the passage of the ball.
  • this expansion does not cause any appreciable deformation of the wall delimiting the bore in which the ball pass is arranged.
  • the ball pass 8 is of cylindrical shape, its diameter being less than that of the bore 6. This ball pass is in this case glued to the shoulder 9.
  • the pass-through could have a square section with rounded corners, the diagonal of which would be equal to or slightly greater than the diameter of said bore 6 (FIG. 3).
  • the body of the pass-through 8 has a cylindrical part, provided with a wide groove 10 and ends in a frustoconical part 11, so as to obtain two bearing zones 12 and 13 of same diameter, slightly larger than that of bore 6.
  • the frustoconical part 11 also offers the advantage of ensuring even better the closing of the passage hollowed out by the bullet when it crosses the body, by the action of the pressure of the gases in the barrel of the launcher rifle.
