Definitions

  • the invention relates to a gun barrel with an integrated cartridge guide.
  • the invention also relates to a repeating rifle with such a gun barrel.
  • a trouble-free cartridge feed into the chamber of a barrel is an important prerequisite for proper functioning of handguns. In particular, it must be ensured that when loading the handgun there is no jam or malfunction caused by the cartridges and that different types of ammunition without interference in the Cartridge chamber arrive. In order to avoid such disturbances, weapons are already known, in the course of which special cartridge feeds are provided to support the cartridge feed to the cartridge chamber.
  • a feeding device which assists in feeding a cartridge into the chamber of an automatic weapon.
  • the feed device comprises a pivotable, spring-loaded feed lever which is arranged near the cartridge chamber of the weapon.
  • the cartridge is conveyed in the direction of the cartridge chamber via the breech block, the nose of the cartridge initially pressing against the free end of the feed lever.
  • the pivotable feed lever which guides the cartridge into the cartridge chamber, is pressed into a recess provided for receiving the feed lever as the cartridge advances.
  • the recess provided for the feed lever is, however, susceptible to contamination, which can impair the functioning of the feed lever and thus the safe feeding of the cartridge.
  • the manufacture and replacement or cleaning of the feed device is relatively complex.
  • a gun barrel with a cartridge guide is disclosed.
  • the cartridge guide consists of two parts designed in the form of half sleeves, of which the upper half sleeve is arranged in the gun barrel and the lower half sleeve is arranged on the axially movable bolt.
  • the half-sleeve fastened in the rifle barrel is fixed in the barrel and the lower half-sleeve is displaceable in an enlarged rear part of the barrel that is coaxial with the barrel bore.
  • a multi-part cartridge holders for use in a gun barrel are disclosed.
  • the cartridge holder consists of three pincer-shaped segments and is pushed into a rear position by spring-loaded pins.
  • the object of the invention is to create a rifle barrel and a repeating rifle with such a rifle barrel which enable improved cartridge feed.
  • the at least one guide element is guided displaceably in a guide receptacle running parallel to the barrel bore in the rifle barrel.
  • the guide element can thus be shifted between an extended guide position and an inserted firing position.
  • the movement of the cartridge when it is inserted into the cartridge chamber is limited via the guide element and the cartridge is guided.
  • the guide element is pushed into the barrel and is well protected there.
  • the guide element is pin-shaped and the associated guide receptacle is designed as a bore.
  • the pin-shaped guide element can be guided precisely in the bore and the guide receptacle designed as a bore is well protected from contamination and malfunctions caused by it.
  • the cartridge guide has two guide receptacles which are arranged above the cartridge chamber and are parallel to one another and each have a guide element therein which can be displaced parallel to the barrel bore.
  • the guide elements serve as a delimitation between which the cartridge, in particular the projectile protruding obliquely upward from the magazine during tracking, can be guided and the cartridge can thus be safely conveyed into the chamber.
  • the at least one guide receptacle and the guide element which can be displaced therein are preferably arranged above the cartridge chamber. In this way, cartridges can be guided, which are tracked by a magazine arranged below the barrel.
  • the guide element is preferably guided axially displaceably within the guide receptacle between an inserted firing position and an extended guide position.
  • the guide element is expediently pressed into the extended guide position by a spring element.
  • the spring element designed as a helical compression spring in an advantageous embodiment, can be arranged in the guide receptacle.
  • a stop element assigned to the guide element can limit the displacement of the guide element within the guide receptacle during the movement into the extended guide position and thereby prevent the guide element from falling out of the guide receptacle.
  • the stop element for example designed as the head of a screw, can interact with an edge or step on the guide element.
  • the cartridge guide can also have a feed ramp arranged in the opening of the gun barrel.
  • the feed ramp further restricts the clearance for the cartridge within the opening and thus further reduces the possibility of tilting or jamming.
  • This The feed ramp is expediently exchangeable and can thus be adapted to different cartridges if necessary.
  • the feed ramp preferably has an insertion bevel that rises in the direction of the cartridge chamber for the safe insertion of the cartridge into the cartridge chamber.
  • the invention also relates to a repeating rifle with such a rifle barrel and a breech which contains a chamber cooperating with the rifle barrel.
  • the at least one guide element is displaceable through the chamber engaging in the opening at the rear end of the gun barrel and can be pressed into the guide receptacle.
  • FIG. 1 the rear part of a rifle barrel 1 according to the invention with an integrated cartridge guide 2 is shown in an exploded view.
  • the Cartridge feed 2 comprises a feed ramp 3 and two guide devices each formed by a pin-shaped guide element 4 and an associated spring element 5.
  • the rifle barrel 1 fastened to a system case 7 via bolt-shaped retaining elements 6 contains, in a manner known per se, a barrel bore 8 with a cartridge chamber 9 and an opening 10 at a barrel end 11 of the rifle barrel 1 for receiving a chamber 12 of a slide that is slidable on the system case 7 13.
  • a removable trigger unit 14 with a magazine 15 for receiving several cartridges is also arranged in the system box 7.
  • the two pin-shaped guide elements 4 and the spring elements 5, which are designed here as helical compression springs, are arranged in two guide receptacles 16 arranged above the barrel bore 8 and parallel to it.
  • the guide receptacles 16, which are both parallel to one another and also run parallel to the barrel bore, are designed as bores in the exemplary embodiment shown.
  • the two pin-shaped guide elements 4 are guided displaceably in the guide receptacles 16, which are designed in particular as blind holes, and are pressed by the two spring elements 5 in the direction of the rear end of the gun barrel 1.
  • the guide receptacles 16 are designed in such a way that they can completely accommodate the spring elements 5 and the pin-shaped guide elements 4 and the pin-shaped guide elements 4 can be pressed against the force of the spring elements 5 to the bottom 17 of the opening 10 at the barrel end 11 of the barrel.
  • the pin-shaped guide elements 4 are guided axially displaceably within the guide receptacles 16 between an inserted firing position and an extended guide position.
  • a stop element 18 interacting with the guide elements 4 is also arranged in the gun barrel 1 to limit the movement of the pin-shaped guide elements 4 in the direction of the chamber 12 or the rear end of the gun barrel 1.
  • the Stop element 18 is formed by a retaining screw screwed into a threaded hole 19 in the bottom 17 of the opening 10 in the axial direction of the gun barrel 1.
  • the feed ramp 3 for feeding a cartridge to the cartridge chamber 12 is also arranged within the opening 10.
  • the feed ramp 3 arranged below the cartridge chamber 12 is fixed by a screw 23 and has an insertion bevel 24 that rises in the direction of the cartridge chamber 12 and has a half-shell-shaped inner contour that is adapted to the outer contour of the cartridge.
  • Fig. 5 shows the feeding of a cartridge into the rifle barrel 1 according to the invention.
  • a new cartridge 25 fed from the magazine 15 is pushed forward in Pushed towards the chamber 9.
  • the cartridge 25 is initially steered obliquely upwards via the feed ramp 3.
  • the projectile 26 of the new cartridge 25 comes to rest on the underside of the guide elements 4 protruding into the opening 10, the cartridge 25 is deflected and guided into the cartridge chamber 9.
  • the guide elements 4 ensure the safe insertion of the cartridge 25 into the cartridge chamber 9 without jamming or tilting.
  • the chamber 12 not only pushes the cartridge 25 completely into the chamber 9, but also the guide elements 4 are pressed against the force of the spring elements 5 until the chamber 12 comes to rest on the bottom 17 of the opening 10 and is locked against the gun barrel 1.
  • the pin-shaped guide elements 4 move back into the FIG Figure 5 shown starting position. Then another reloading process can take place.
