Definitions

• the invention relates to a self-loading handgun with a barrel, a magazine for receiving cartridges and a movable breech which has a breech head,
• a number of radial locking lugs are arranged along its circumference at arrangement locations which are distributed around this circumference,
• the weapon described has a breech with a breech head which can be installed in one of two installation positions. This allows the weapon to be ejected either to the right or to the left. Left-handed people can now optimally operate such a weapon, depending on their suitability. In the end, to set such a weapon, it is only necessary to install the breech head accordingly.
• Such a closure head has a number of arrangement points around its circumference, at which radially extending projections, the so-called locking lugs, are arranged.
• the arrangement locations are usually distributed uniformly, that is to say they have the same angular distance from one another, based on the longitudinal central axis of the barrel and the breech.
• the locking lugs run into complementary, stationary longitudinal grooves, pass through them and then finally engage behind them as a result of a rotation of the closure head about its longitudinal central axis. This rotation sweeps over an angle which is approximately half of the above-mentioned angular distance and is called the locking angle.
• a cartridge extractor is attached to the periphery of the front end of the head, which follows the rotation of the head.
• the breech head should therefore ideally be extended in front of the locking lugs to accommodate the cartridge extractor without one to impair the accuracy of the arrangement of the locking warts.
• Such an extension of the breech head contradicts the attempt to make the weapon as short as possible. It would also be possible to increase the radial distance of the locking lugs from the longitudinal central axis, but this would increase the bulkiness of the weapon.
• the invention may provide a self-loading weapon with a cartridge extractor of the type mentioned in the introduction, in which the above-mentioned problem of high shot accuracy with a sufficiently high number of locking pins is solved as advantageously as possible.
• the cartridge extractor is arranged at an arrangement point instead of a locking lug and is located horizontally next to the center axis of the barrel in every installation position of the breech head and when the breech is unlocked.
• the positions taken by the cartridge extractor are diametrically opposed to one another in such a way that the ejection takes place horizontally in each of the installation positions.
• D it has the advantage that bulky reconnaissance and targeting devices can be attached above the weapon (such as an active night vision device with infrared headlights).
• the enemy can be horizontal ejected cartridge cases see worse than those that are ejected obliquely upwards beyond the cover and reflect there under unfavorable sunlight or could be detected by an infrared observation device at night.
• the even number of arrangement points is necessary so that there is an odd number of locking lugs.
• the cartridge extractor only occupies a horizontal position when the shutter is unlocked.
• the cartridge extractor is pivoted together with the locking lugs by about half a pitch between the arrangement points.
• the CH-PS 580 269 shows a closure, the direction of ejection is adjustable. However, this closure has an odd number of locations.
• DE-AS 24 43 044 shows a closure head with ten locking lugs; it is not clear where the extractor should sit.
• the bottom of the top cartridge was gripped behind in the middle. In the case of the usually zigzag arrangement of the cartridges in the magazine today, however, the top cartridge was gripped off-center. Then there might even be a risk that the following cartridge would also be streaked by the locking lug because the locking lug protruding vertically downwards extends far into the magazine.
• a receptacle in the form of an elongated groove is provided on the rear side of the cartridge chamber for each locking lug, which is directed toward the longitudinal axis of the
• the two horizontal longitudinal grooves which are arranged on both sides of the longitudinal center axis, are neither widened nor deepened.
• a locking device is also installed at the location opposite the cartridge extractor. lungs arranged. In order to prevent the cartridge extractor from starting up, each of these two longitudinal grooves is chamfered. This forms an inlet, against which the cartridge extractor starts gently, in order then to be pressed into its desired position (claim 4).
• the angular distance between the arrangement points is ideally the same.
• the arrangement points immediately adjacent to the two lowest / uppermost arrangement points can be displaced in such a way that the gap between them can run over the respective magazine lip. This makes it possible to completely adapt the weapon to existing magazines by moving the locking lugs - even though the main dimensions of the breech would actually always require a separate magazine.
• the angle from the center of the horizontal locking lug (or the cartridge extractor) to the center of the next locking lug is approximately 30 ° each, from the center of this to the center of the following each around 42 ° (the gap between these two locking lugs runs over a magazine lip in each case away), and between the centers of the two bottom and top locking lugs 36 °.
• a self-loading rifle that is set up for the .223 cartridge and in which the ejection direction is horizontally right or left due to the corresponding installation of the breech block, e.g. the magazine of the US rifle M16 can be used.
• Fig. 1 shows a section through parts of a rapid-fire rifle in the vertical longitudinal median plane
• Fig. 2 is a view from the direction of the barrel to the rear against the locking head and magazine.
• the drawing shows essentially only the barrel 1, the breech 3 and the magazine 5 of a rapid-fire rifle.
• the barrel 1 sits with its rear end in a sleeve 7, which is firmly anchored in the housing of the rapid-fire rifle (not shown).
• a cartridge chamber 13 is also formed in the rear end of the barrel 1.
• the axis of the barrel bore defines a longitudinal central axis 15.
• a ring of longitudinal grooves 9 is formed, which open into an annular groove 11 which is adjacent to the cartridge chamber 13.
• the closure 3 is translationally movable along the longitudinal central axis 15. It is formed from a closure carrier 17 and from a closure head 19. The latter is rotatably and slowly attached to the fastener carrier 17.
• a ring of ten arrangement points 20 is arranged distributed over the circumference, which correspond to the positions of the longitudinal grooves 9 shown in FIG. 1.
• a locking lug 21 is arranged at each of nine of these arrangement points 20, whereas a cartridge extractor in the form of an extractor claw 23 (FIG. 2) is arranged at the tenth arrangement point.
• an ejector 25 is mounted opposite the extractor claw 23.
• the magazine 5 has two magazine lips 27 on its upper side, which hold back the cartridges (not shown) that are guided from bottom to top.
• the cartridges In this magazine 5 are the cartridges m zigzag arrangement, so that they are held alternately by one or the other magazine lip 27.
• the ten locations 20 for the locking lugs 21 and the extractor claw 23 are arranged symmetrically with respect to one another with respect to a horizontal line 29. On this horizontal line 29 is the location 20 for the Extractor claw 23 and the opposing locking lug 21. From each of these horizontal arrangement points 20 two further arrangement points 20 follow downwards. These are arranged such that between the two locking lugs 21 a magazine lip 27 fits at each of these arrangement points.
• the locking lugs 21 at the two lowest, ie deepest, arrangement points 20 are additionally aligned such that one of them can alternately grip the cartridge located in the magazine 5 in the center from behind.
• the nine locking lugs 21 are each exactly in front of an elongated groove 9.
• the tenth elongated groove 9 is free. It is one of the two lying on the horizontal 29
• the closure head 19 can be installed in two different positions: in both installation positions, the extractor claw 23 lies on the horizontal 29, but depending on the installation position either on the left or on the right side of the closure head (FIG. 2).
• These two longitudinal grooves 9 have an outwardly widening inlet 31 which can press the extractor claw 23 when the closure 3 is closed.
• the breech head 19 When the breech head 19 has arrived at the cartridge chamber 13, it performs a rotation in which the locking lugs 21 run in the annular groove 11. The locking lugs then engage behind the material webs between the longitudinal grooves 9. The recoil which occurs when the shot is fired is thus introduced fully into the sleeve 7 and via this into the weapon housing.
• arrangement locations 20 can also be distributed in other ways, in particular with the same mutual angular distance.
• arrangement locations 20 could also be distributed in adaptation to any magazine, not just the magazine for the US M16 rifle.
• the handgun according to the invention can be set up for any suitable cartridge, not just the .223 Remington cartridge.
