Definitions

  • the object of the present invention is a low-weight, direct-percussion grenade-launcher.
  • the grenade-launchers considered light weapons, must be transported by the detachments of infantry, and should therefore meet requirements of low-weight, reliability and safety.
  • the purpose of the present invention is to provide a grenade-launcher having a low weight, the mechanisms of which are simple, and reliable, furthermore rendering the grenade-launcher easy to use, and which furthermore supplies ranges of the order of at least 900 metres.
  • a low-weight, direct-­percussion grenade-launcher which is constituted by a launching barrel fastened to a breech, with said breech being provided with a a click mechanism for releasing a percussion pin, characterized in that said percussion pin is a long-stroke percussion pin, guided to slide inside a seat communicating with said barrel and provided in a bottom portion of said barrel, in order to hit a bottom of a cartridge inserted inside said barrel, with the stroke of said percussion pin being long enough in order to eject said cartridge from said barrel after the explosion, with said barrel being of a length at least equal to the length of a cartridge with the relevant projectile, the inner volume of said barrel being used as the expansion chamber for the launching gases.
  • the stroke of said percussion pin is at least equal to the length of the only cartridge case of said cartridge.
  • the length of the barrel of the grenade-launcher according to the present invention is equal to the length of a cartridge including the projectile.
  • a grenade-launcher according to the present invention is generally indicated, which is constituted by a launching barrel 11 and by a breech 12 fastened to the bottom portion of the barrel, and provided with a through-seat 13.
  • a click mechanism is provided, which is constituted by a lever 14 connected with an element 15 sliding inside the interior of the breech, whilst the lever 14 is free of moving inside the through-­seat 13.
  • the energy for the motion of the element 15 is supplied by a spring provided under the element 15, and in engagement with it.
  • a percussion pin 16 extends, a part of which is housed inside the breech 12, and the remainder thereof is housed inside a seat 17 provided in the bottom portion of the launching barrel 11.
  • the seat 17 opens in a burst chamber 18 provided inside the interior of the barrel, and having such a size that it can contain a cartridge 19 constituted by a cartridge case 20 and a projectile 21. Externally to the barrel 11, a portion of a grenade 22 is schematically shown.
  • the percussion pin 16 After the explosion, the percussion pin 16, continuing running upwards, will eject the cartridge case 20 of the cartridge 19, thanks to its stroke, at least equal to the length of the cartidge case 20.
  • the grenade-launcher according to the present invention combines an extreme structural simpleness, to full advantage for the lightness of the weapon, with the easiness of charging and versatility of use, characteristics, these, which result in the possibility of using different types of cartridges with or without projectile, and in having an optimum fire rapidity.
