Definitions

  • the invention relates to a cartridge for firearms, with a closed on the bottom, a propellant charge and an ignition means receiving plastic sleeve, the head side forms a sleeve-like socket for inserting a full-caliber projectile, the head part forming the socket in the area of the projectile tip in an axially normal end face ends and has a jacket which tapers essentially concavely on the outside towards the end face.
  • Cartridge casings not only serve to connect and protect the projectile, propellant charge and ignition means, but above all they should also provide the projectile with a firm, centering holder and help seal the hold of the firearm when the propellant charge is fired and fired.
  • the sleeves for sharp cartridges have so far been predominantly made of metal, which requires expensive manufacture and a high cartridge weight. Attempting to use caseless cartridges has not been successful since the cartridge, without the protective, guiding and sealing functions of the sleeve, is far too unsafe to operate and makes the firearm unreliable.
  • plastic cartridge case it has also been proposed to use a plastic cartridge case to take advantage of a cartridge case while still reducing manufacturing costs and cartridge weight.
  • plastic sleeves are manufactured according to DE-A-22 09 459 as a hollow cylinder closed at one end, which contain the propellant charge and the ignition means in the closed bottom area and into which the projectile, which has its own sleeve with an external thread, is screwed to the tip from the open end is, but the production remains quite expensive.
  • the ground igniter requires a special, correspondingly solid sleeve base and brings at the same time a weak spot in the ground with it, which can lead to leaks when firing the shot.
  • the invention is therefore based on the object of providing a cartridge of the type described at the outset, which can be produced particularly efficiently with reliable shot performance, has no weak spots on the bottom and, above all, ensures reliable ignition.
  • the jacket of the head part has a circumferential annular groove in the end face opposite the end face, open into the sleeve interior, for receiving the ignition means.
  • the cartridge can be provided with an edge detonator in the head region, which causes the propellant charge to burn progressively from the head to the bottom of the sleeve, which prevents the unburned powder of the propellant charge from penetrating into the barrel and increases the effect of the propellant charge.
  • the rim fuse extends around the socket, the projectile can serve as an abutment for the ignition process, in which the ignition means must be squeezed accordingly by a suitable ignition device, and special measures for the design of such abutments are unnecessary.
  • the result is a particularly simple, functional cartridge that has a sleeve that is fully closed on the bottom and does not fear leaks.
  • the jacket narrows conically on the inside in the mouth region of the socket, the head part preferably forming a separate component separate from the remaining sleeve part and consisting of a glass fiber reinforced plastic.
  • the jacket gets a narrowing muzzle through this jacket, which not only brings about a firm and tight fit of the bullet, but above all also leads to a widening of the jacket when the bullet is driven out and thereby to an increase in its sealing effect.
  • the head part also forms its own component, the entire production process can be rationalized are, with the sleeve parts can be combined with different head parts without difficulty to several cartridge types, such as sharp cartridges, blank cartridges, light cartridges or the like. to manufacture.
  • the head part alone can then be reinforced with glass fiber in order to achieve a special strength in a cheap manner to improve the projectile support and guidance.
  • a cartridge according to the invention is schematically illustrated using a partially sectioned side view.
  • a cartridge 1 has a two-part sleeve made of plastic 2, one part, the sleeve part 2a, holding a propellant charge 3 and the other part, the head part 2b, forming a sleeve-like socket 4 for holding a projectile 5 which extends to the tip in this version 4 is.
  • the head part has a jacket ending in an axially normal end face, which tapers concavely on the outside towards the end face and tapers conically on the inside in the region of the mouth 4a of the socket.
  • the cartridge 1 has an edge detonator in the head area.
  • the head part 2b forms a separate component with the projectile 5 and the detonator 6, 7, which is glued or welded to the sleeve part 2a receiving the propellant charge 3 to complete the cartridge.
  • the largely protected against external loads holding the projectile 5 within the sleeve 2 allows the use of a plastic sleeve, wherein the head part 2b forming the socket 4 for the projectile 5 can have a sufficiently large wall thickness ensuring the required strength.
  • the correspondingly long version 4 not only offers a secure fit for the projectile 5, but also gives it a good centering guide and a tight seal.
  • the ignition means 7 in the area of the head part 2b leads to a complete combustion of the propellant charge 3 within the sleeve part 2a and makes the cartridge 1 particularly effective, for which purpose Above all, it comes that the head part 2b can fulfill an important sealing function in the loading space with its special jacket shape and ensures a really gas-tight use of the cartridge when firing the shot.
