Definitions

  • the present invention relates to an insert for a firearm, for example for a rifle or a handgun, by means of which ammunition of smaller caliber can be fired than that for which the firearm in question is built.
  • the invention also relates to a method by means of which the operation run associated with this application can be produced.
  • Such missions are mainly used in large-caliber rifles or handguns for practice purposes, so that the shooter can practice aiming and firing at short distances.
  • this small-caliber ammunition is considerably cheaper and its firing produces a significantly lower shooting noise compared to large-caliber ammunition. That's why such missions for shooting training very much in demand.
  • Shooting ammunition of smaller caliber is particularly suitable for training beginners, since the shooter can be accustomed to handling the large-caliber firearm and can gain experience with aiming and firing. Shooting is cheaper by using such inserts or much more efficient at comparable costs, since more ammunition can be fired.
  • the firing of ammunition of this caliber is not tied to special regulations, so that a shooting range does not always have to be visited, but the large-caliber firearm is used to fire such ammunition on public grounds, for example in a forest or on Wiesland, but also on private property can.
  • a 4 mm ammunition which is commercially available under the designation M20, is used to fire at a distance of 10 meters.
  • Such inserts for large-caliber firearms belong to the prior art.
  • the so-called Lienhard insert became known for the Swiss carbine at the end of the 1930s. This can also be used in the Swiss assault rifle 57, which has the same caliber as the carbine.
  • This Lienhard insert comprises on the one hand an operational run and on the other hand a charging sleeve.
  • the insert consists of a tube with an outer diameter which corresponds to the caliber of the rifle barrel, that is to say has a diameter of 7.55 mm for the rifles mentioned.
  • the insert barrel has an inside diameter that is at least 4 mm everywhere. Trains with a depth of 0.15 mm are gouged out of the inside of the barrel, which wind a quarter turn over the length of the barrel. The inside diameter between two opposite trains is therefore 4.3 mm and between two opposite fields 4 mm. A ball of caliber 4 mm shot through the barrel, which in fact has a diameter of 4.3 mm, is pressed into the trains and is given a twist by the twisting of the fields running between the trains, which causes the trajectory stabilized. For use, the Lienhard barrel insert is inserted into the barrel of the relevant rifle on the lock side. Then the associated Lienhard loading case is prepared.
  • This essentially consists of a hollow cylinder, on the front end of which the ball to be fired is placed and on the rear side of which a primer is inserted which is separate from the ball.
  • the firing pin of the rifle slide hits the bottom of the primer and the resulting explosion pressure acts through the loading sleeve and drives the bullet through the barrel.
  • the loading sleeve has to be laboriously extracted from the cartridge chamber and freed from the fired primer by means of a piercing needle. Then the charging sleeve must be re-fitted with a ball and primer and then reinstalled in the barrel. The Reloading therefore requires time-consuming manipulation.
  • a charging sleeve consisting of two separable parts has also become known for Lienhard use.
  • the front took up the ball to be fired at the front and the charge separated from the ball, the primer.
  • the rear part could be pretensioned on the base of the primer by means of a screw connection, so that a blow to the rear end of the charging sleeve propagated onto the bottom of the primer and thus caused the charge to explode.
  • the so-called Walter emergency run has become known.
  • This has the shape of the GP 11 rifle cartridge, which is fired with both the carbine and the assault rifle 57. It is therefore 70 mm long and has an axially extending through hole of 4 mm in diameter, into which trains are planed with a twist, so that the diameter between two trains is 4.3 mm.
  • this insert which is to a certain extent formed by the cartridge itself, has two circumferential grooves in which rubber-elastic O-rings are inserted.
  • the Walter insert barrel is loaded by using the ammunition on its rear side.
  • This ammunition to be fired consists of a cartridge case, which is provided directly with the projectile, a ball with a diameter of 4.3 mm, and is known under the name M20.
  • C0 2 insert Another solution for practice shooting with large-caliber rifles is provided by a rifle insert known as the C0 2 insert, which was developed for short-range shooting with the new Swiss assault rifle 90, which is known as a private weapon under the name EP 90.
  • This rifle insert consists of a closure piece into which a commercially available C0 2 cartridge can be inserted, as is known, for example, for filling cream blowers. Sales This rifle insert is used to shoot a bullet with a caliber of 5.5 mm, which corresponds to the actual caliber of this rifle. In reality, the balls may have a slightly larger diameter in order to take into account the extension of the barrel which results from the imposition thereof.
  • the invention solves this problem with an insert for firearms for firing ammunition of smaller caliber than that for which the firearm in question is built, with an insert barrel and a loading sleeve made of two separable parts, which is characterized in that at ei ⁇ With an inside diameter of the insert barrel of less than 5 mm, the ratio of the mass of its inside to its outside diameter is more than 60%, and that in the front Ren part of the loading sleeve, a one-piece ammunition of cartridge case and bullet can be used and in the rear part of which an ignition pin is axially movably mounted.
  • the invention further achieves the object by means of a method for producing an insert barrel for this insert, which is characterized in that the trains and fields in the barrel are kneaded out of the inside of a tube with a larger outside and inside diameter than the barrel to be manufactured by means of cold forming are made by several hammers arranged peripherally around the tube simultaneously acting radially on the outside thereof and against a stationary core located therein with the negative forms of the corresponding trains and fields, while the machined tube is pulled from the core under the machining hammers with appropriate twisting is, after which it is turned outside and polished.
  • the use according to the invention permits the firing of ammunition of reduced caliber with firearms which are designed for larger-caliber ammunition.
  • the loading sleeve of the insert according to the invention can be pointed into the usual ammunition magazine of the firearm and can be handled in exactly the same way as the correct ammunition.
  • the filled magazine can be shot shot after shot, whereby only a manual loading movement is required between the shots.
  • the loading sleeve is ejected automatically, like a shot gun cartridge Sleeve.
  • the special manufacturing process for the associated operational run enables such an inexpensive manufacture that an operational run that can actually be inserted into the gun barrel can be offered for the first time.
  • the operational run according to the invention is of such convincing precision that the effectiveness of the shooting training with such ammunition of smaller caliber can be considerably increased.
  • the scattering fluid is sufficient even at a shooting distance of 20 meters in order to practice even at this distance.

  • the ammunition 7 can be used there by inserting it into the front part 1 of the loading sleeve from behind and finally holding it in a form-fitting manner in the mouth region 5, 6, as is shown in FIG. 1.
  • the front part 1 of the loading sleeve is held upright for loading, so that the largest inside diameter is at the top, after which the ammunition 7 can be dropped into this front part 1 of the loading sleeve.
  • the front part of the charging sleeve is shown in a view from behind. Seen together with the longitudinal section, it can be seen that the region 3 with the second largest diameter has two opposing tapered regions 8 at the rear, each of which extends by approximately 90 ° of the circumference and lies opposite one another. As a result, recesses 9 are formed which can be seen from behind in the view. This Recesses 9 and the tapering 8 are part of a bayonet lock, as will become clear later.
  • FIG. 2 shows the male part 10, which can be plugged into the female part 1, which was shown in FIG. 1 and just described.
  • This male or rear part 10 of the charging sleeve according to the invention likewise forms a hollow cylinder, in the interior of which an ignition pin 11 is guided in the axial direction and has a correspondingly small diameter.
  • This firing pin 11 is additionally guided at the rear by means of a guide bushing 12 and secured against falling out. It has a thickening 13 in its central area, which is somewhat shorter than a corresponding recess 14 from the hollow cylinder inner wall, so that the thickening 13 is guided in this recess 14, but the firing pin 11 extends over a certain area is movable in the axial direction.

They are then secured against twisting before being disassembled, the thickenings 20 on the rear part 10 rotating in the manner of a bayonet lock over the corresponding tapering 8 on the front part 1 and finding a firm stop or support thereon. A slight increase in the abutting surfaces of the thickenings 20 or tapering 8 on the two parts 1, 10 results in an increasing static friction by rotating the parts 1, 10 against one another, which secures the parts 1, 10 against loosening .

Abstract

Un ensemble complémentaire comprend un canon insérable (27) et une douille de chargement (21). Le rapport de masse entre le diamètre intérieur et le diamètre extérieur du canon insérable (27) s'élève à plus de 60 % dans le cas d'un diamètre intérieur inférieur à 5 mm et la face extérieure du canon insérable (27) est totalement lisse, de sorte qu'il s'ajuste étroitement dans le canon de l'arme utilisée. La douille de chargement (21) correspondante se compose de deux pièces séparables (1, 10). Dans la pièce antérieure femelle (1) on peut introduire la munition de petit calibre (7). La pièce mâle postérieure (10) contient un percuteur (11) axialement mobile dans son alésage intérieur. La pièce postérieure (10) de la douille de chargement est insérée dans la pièce antérieure (1) et est fixée sur celle-ci au moyen d'une fermeture à baïonnette. La douille de chargement (21) assemblée avec la charge (7) a des dimensions extérieures correspondantes à celles d'une cartouche communément utilisée avec l'arme en question et peut être manipulée de la même façon. Plusieurs douilles de chargement (21) peuvent notamment être stockées dans le magasin de l'arme, de sorte qu'un seul mouvement manuel de chargement suffit pour recharger. Les rayures (28) et les baguettes (29) du canon insérable décrit (27) sont produits par façonnage à froid par des marteaux agencés autour de la périphérie d'un noyau stationnaire qui s'étend sur toute la longueur du canon (27). Les marteaux façonnent un tube standard tandis que le canon (27) façonné par les marteaux est libéré du noyau par traction, avec un mouvement tournant.
