Definitions

  • the invention relates to the design of a handgun, with which gas or signal and shot ammunition can be fired, whereas the prohibited use of live ammunition in the form of a bullet would block the weapon in itself and thereby render it unusable.
  • strangle bores are already provided, which, by reducing the effective cross-section in some areas, prevent the scrap of a full storey, while the shot balls fired from a cartridge experience only an insignificant reduction in the kinetic energy allocated to them (DE-A 2.907931).
  • the object of the invention is to develop a suitable blocking device, preferably for short-barreled handguns (see e.g. DE-A 2 256 522), which is suitable for firing permitted ammunition, e.g. shotgun cartridges, too, but a single shot with full ammunition makes the weapon irreparably unusable.
  • a suitable blocking device preferably for short-barreled handguns (see e.g. DE-A 2 256 522), which is suitable for firing permitted ammunition, e.g. shotgun cartridges, too, but a single shot with full ammunition makes the weapon irreparably unusable.
  • the invention forms a handgun with a short barrel according to the preamble of claim 1 in such a way that a cylindrical separating body is inserted in the barrel at its entrance opening and before a conical widening of its bore, which is on a pitch circle around the core axis over several axially parallel longitudinal bores of smaller caliber.
  • This separating body stands centrally in the way of a full storey fired from the cartridge chamber or the drum of a weapon and, due to the longitudinal bores arranged in a circle around the massive central area, initially compresses the projectile that hits it, which is then broken down into several parts.
  • These projectile parts are elongated when penetrating the longitudinal bores and meet the conical widening of the actual bore when they leave it.
  • the individual parts are concentrated in front of the barrel bore, jamming each other and thereby blocking the barrel, which makes the weapon unusable and can only be repaired by professional intervention.
  • the entrances to the cylindrical longitudinal bores are provided with a sufficient countersink or chamfer.
  • wedge-like cutting edges are formed on the outward-facing end face of the separating body between the different entrance openings, which are useful for better splitting and disassembly of the impacting full storey.
  • this design of the openings favors the unimpeded entry of the bullets of a shot load, which are guided into the barrel by means of the conical widening after the split through the longitudinal bores and can thus pass through the locking device of the weapon without significant obstacle.
  • the separating body which can be inserted into a cylindrical recess of the barrel in a form-fitting manner, has one or two ribs projecting in an annular manner on its outer circumference.
  • the steel barrel 1 in connection with the separating body 2 made of hard metal has been injected or cast into the metallic barrel 3 of the weapon in the course of production.
  • the bore 4 on the input side has a conical widening 5 which runs outwards into a cylindrical recess.
  • the cylindrical separating body 2 is inserted into this recess in a form-fitting manner and, according to the design of the barrel surface, is fixed within the barrel 3 with the aid of annular ribs 6 so as not to be displaceable in the axial direction.
  • the separating body 2 shown separately in the drawing preferably has four longitudinal bores arranged symmetrically to one another and axially parallel on a pitch circle around the massive axial region of the separating body 2 7. These four bores 7 are provided on the outer input side with a corresponding countersink or chamfer 8 so that wedge-shaped cutting edges are formed on the end face of the separating body 2 between the relevant openings of the longitudinal bores 7. On the inner exit side, the longitudinal bores 7 open into the actual bore 4 via the conical widening 5.
  • the shot jet 9 indicated on the left next to the barrel 3 in FIG. 1 is introduced into the longitudinal bores 7 at the end face of the separating body 2 by means of the chamfers 8.
  • the shot pellets 9 are deflected again as they leave the longitudinal bores 7 by the conical widening 5 in order to leave the barrel bore 4 at the muzzle of the weapon without significantly affecting the movement or gas pressure energy which was given to them when fired.
  • an inadmissibly fired full storey 10 hits the end face of the separating body 2 centrally.
  • the projectile 10 compresses due to its kinetic energy and is divided into four parts at the wedge-shaped cutting edges between the openings of the longitudinal bores 7 (see FIG. 5). These parts pass through the separating body 2 and are given a certain lengthening due to the shape.
  • the four parts of the full storey 10 meet the conical widening 5 and, when trying to penetrate into the barrel bore 4, are compressed at their entrance opening and are definitely fixed.
  • the full storey 10 loses part of the kinetic energy that it was given by the gas pressure from phase to phase and in the shortest possible way in order to finally come to a complete standstill when it enters the narrower barrel bore 4 and thus the weapon is blocked by blocking it to make a running area difficult to access.

Claims (3)

1. Arme à feu portative courte avec un dispositif de verrouillage monté dans le canon (1) de l'arme empêchant le tirage de projectiles (10) caractérisée en ce qu'un élément de séparation cylindrique (2) en métal dur est installé dans le canon en acier (1) à l'ouverture d'entrée et devant un espace creux en forme conique, cet élément disposant, sur un cercle gradué autour de l'âme du canon, de plusieurs perçages longitudinals (7) de façon symétrique ainsi que parallèle à l'axe.
2. Arme à feu portative selon la revendication 1, caractérisée en ce que les entrées des perçages longitudinals (7) à l'intérieur de l'élément de séparation (2) sont équipées d'un biseau ou chanfrein (8) au côté extérieur de cet élément pour former des arêtes coupantes cunéiformes (afin de décomposer le projectile).
3. Arme à feu portative selon les revendications 1 et 2, caractérisée en ce que l'élément de séparation (2) à inserer à fermeture géométrique dans un espace creux cylindrique du canon en acier (1) est équipé de nervures annulaires (6) sur sa circonférence servant à la fixation à l'intérieur de la partie métallique du canon (3) de l'arme.
