Definitions

  • the invention relates to a large-caliber gas pressure supercharger with a central force introduction part which receives the rear end of the barrel and the locking abutment of the closure
  • This gas pressure supercharger uses the principle of closure of a handgun with a locked closure and a closure carrier wherein the closure head is penetrated by a locking block which transversely is movable to the direction of movement of the closure and in the locking position engages over a large area locking projections.
  • large caliber is meant in particular a rifle with a caliber or largest sleeve diameter of the cartridge of more than 15 mm.
  • FR1266597 discloses a large caliber rifle according to the preamble of claim 1.
  • a heavy missile such as a projectile, a sabot projectile, a shotgun, a gas body, or the like
  • the gas pressure is comparatively low, especially in the front of the barrel.
  • the cartridge diameter is greater than 15 mm, the shutter is large and long and thus heavy, so that the forces required to load through are large.
  • the gas pressure since the gas pressure, as already mentioned, is low, the effective area of the gas piston must be large. Accordingly, the amount of gas that is withdrawn from the barrel during firing is also large.
  • recoil loaders which, however, have the disadvantage of being particularly sensitive to differences in recoil.
  • a large anchoring element has recently been provided with a large-caliber rifle for weight savings, to which all occurring forces should act as much as possible.
  • the housing can then be carried out largely in the lightest plastic construction, since it is at most little burden.
  • a gas piston device requires at the tapping point of the barrel, which usually interacts with the gas cylinder, another point of introduction of force and thus builds quite difficult.
  • the invention is therefore the object of developing the aforementioned, large-caliber rifle to the effect that at least one of the problems mentioned above is at least partially mitigated.
  • the invention is based on the object, a self loading rifle for large caliber.
  • Long cartridge shotgun cartridge case with short cartridge case that is lightweight and reliable in transit.
  • the barrel still has a gas removal opening in the force introduction part, and that a gas cylinder is firmly connected to the force introduction part, which is connected to the gas discharge opening, wherein the barrel 101 still in the force introduction part 104 has a gas removal opening 173 and wherein a gas cylinder 171 is fixedly connected to the force introduction part 104, which is connected to the gas removal opening 173.
  • a tube is firmly connected to the closure carrier, the gas cylinder passes through and is penetrated as a receiving tube for a closing spring.
  • the inner surface of the gas cylinder thus has an annular surface, and also the force takes place exactly centric on the closure carrier.
  • the return spring for the closure the so-called closing spring, further penetrates the tube, so that the closure member forming the gas piston is also set back exactly centric and thus can not tilt.
  • the gas cylinder viewed in terms of its diameter, can thus also build shorter than would otherwise be necessary.
  • a rocker arm which is arranged in the closure head, engages on the one hand in the movement path of the closure carrier and on the other hand in the path of movement of the locking bolt and pulls out of its rest position, the locking bolt from the formations of the force introduction part in a movement of the closure carrier.
  • Such a rocker arm is mounted for example on a pivot axis which is arranged transversely in the closure head.
  • such a device can also be formed approximately by a compression spring which pushes out the locking bolt from its rest position when the closure carrier makes room.
  • the invention differs from the effect that two recesses are formed transversely to the locking pin in the closure head, in each of which from behind a hole for a pressure pin and a spring pushing this forward are formed, that in one of the recesses a counter to the force of the pressure pin pivotable extractor is used, and that in the opposite recess as far as necessary a support member is immovably inserted, opposite to the extractor, the bottom of a cartridge or cartridge case laterally supported. Extractor and support element thus face each other (claim 1).
  • the gas removal opening in the force introduction member eliminates its own, force-absorbing enclosure of the gas removal opening. At the same time this is brought far to the rear, where the gas pressure sufficient for unlocking and pressing a heavy closure with a long reload path.
  • the barrel of the weapon according to the invention is preferably, as is common practice, provided with a cartridge chamber, which is formed integrally with the barrel. But it is also conceivable that the cartridge chamber is separated from the barrel.
  • the term "barrel" includes the cartridge chamber, whether it is integrally formed with the barrel or not.
  • the gas removal opening is located at the front end of the cartridge chamber and opens into a bore in the force introduction part, which in turn opens into the front end of the gas cylinder (claim 2).
  • the cartridge chamber is compared to the caliber of the barrel, in extremely large-caliber rifles often quite short; with grenade cartridges of the type described above, the chamber is even extremely short.
  • the slow acceleration of the shutter by the action of the launcher gases is sufficient to ensure before the shutter is opened that the projectile has already left the barrel.
  • the pressure drop takes place in such panoramickalibergewehren usually so early that the overpressure is quite low in the barrel when the projectile leaves the barrel.
  • the force introduction part ensures that even a high pressure is absorbed harmless in the bore and forwarded to a gas cylinder.
  • This gas cylinder is preferably formed in the force introduction part (claim 3) and thus does not require its own, force-absorbing component.
  • the bore may extend obliquely in or against the weft direction to exploit or inhibit the kinetic energy of the launcher gases. Since this kinetic energy is low at the bearing end, it is preferred that the bore extends transversely to the weft direction (claim 4). Thus, the force introduction part can be kept as compact as possible.
  • the gas cylinder which connects directly to the hole, can sit laterally or below the bearing. However, in order not to extend the width of the weapon excessively, and to attach a magazine under the closure, it is preferred that the gas cylinder sits over the cartridge chamber (claim 5). Since the gas cylinder is formed in the force introduction part, so for a very stocky and.besonders also provided in the longitudinal direction short construction.
  • the closure is, as usual, formed of a locked closure head and a closure carrier.
  • the closure carrier forms the gas piston (claim 6).
  • the tube has according to a further embodiment also has the purpose to carry a charging handle, which is either attached to the pipe or can be attached or connected with this for loading (claim 7).
  • a locking bolt passes through the closure head transversely and is pressed by the closure carrier in its rest position in a locking position, in which it engages in embodiments of the force introduction part and thereby locks the closure head (claim 8).
  • the embodiments are advantageously mounted approximately circularly symmetrical to the longitudinal axis of the barrel.
  • the closure head must therefore cover no unlocking distance when it is unlocked, but it is then pulled out only the locking bolt transversely to said longitudinal axis.
  • the device for this purpose can be located above the closure head and does not take up any length.
  • the extended locking pin engages in the closure carrier, so that with its movement of the locking bolt and thus the closure head is entrained (claim 9).
  • a positive connection between the closure head and the closure carrier is made, regardless of how quickly the return of the closure carrier takes place, so also slow loading.
  • the locking bolt on a slot which is penetrated by the firing pin the firing pin has behind the locking bolt on a paragraph, and the slot has a bevel on the rear, which engages the shoulder of the firing pin and this pushes back when the locking pin out of engagement is pulled with the training of the force introduction part (claim 10).
  • the firing pin is forcibly pushed out of engagement with the cartridge after firing and can not reach the cartridge bottom when the shutter is unlocked.
  • neither a rupturing primer (so-called. "Kapselr employer”) hold the firing pin forward, nor a premature ignition done, so if the closure head is not locked. This guarantees reliability even in the case of rare disturbances.
  • the support member supports the cartridge case after removal, so that the cartridge case does not slip off the opposite extractor claw.
  • the closure makes after the shot first an acceleration phase and then a deceleration phase. During the deceleration phase, the bottom of the accelerated cartridge shell rests firmly on the thrust floor. "Shock" is called the front surface of the closure head.
  • the cartridge case is very short, so they may still in the acceleration phase or shortly after this already leaves the chamber. Since the support element and the extractor sit in similar recesses, they can be exchanged for each other. Thus, it is possible to change the direction of ejection of the rifle, so that the rifle is easily adaptable to right or left shooters.
  • the application thus discloses a handgun with a locked closure and such a closure itself.
  • This closure has a closure head and a closure carrier.
  • This closure should be particularly short build, but able to absorb high recoil.
  • the closure has a locking bolt, which is movable transversely to the direction of movement of the closure and engages in the locking position over a large area locking projections.
  • the application discloses a locked self-loading firearm with a rigid barrel with cartridge chamber, a lockable against the barrel closure head and a relative to the closure head movable closure carrier on which a closing spring is supported, wherein between the closure carrier and the closure head an additional, strong spring assembly is arranged, over which the heavy closure carrier is supported with locked closure head on the latter.
  • the shutter tends to open already when the bullet is still in the barrel or the gas pressure has not fallen far enough.
  • shotguns have proven to be a recoil loader system in which the barrel and closed shutter first run back over the full return path, and the pressure almost completely dissipates (Browning, Walther). Then the shutter remains stationary in the rearmost position, and the barrel is braked under the force of a spring and guided forward relatively slowly. Together with the closure and the cartridge case remains stationary, so that it is gently pulled out of the barrel. Excessive longitudinal forces in the cartridge case do not occur. After ejecting the cartridge case, the closure snaps forward under the action of the closing spring and takes with it a new cartridge.
  • Gas pressure loaders have long been known for self-loading and have proven there. Indicaladeflinten but they require a defined gas pressure and a slightly undressing, resistant shotgun cartridge case. With modern, heavy-duty cartridges featuring a long-sleeve metal cartridge bottom and a longitudinally-ribbed plastic sleeve body, such gas-through guns operate flawlessly. Compared to cartridges of poor quality but they do not have the unpretentiousness of recoiling loading shotguns.
  • the gas pressure boosters in the hip stop function as well as in the shoulder stop.
  • gas pressure boosters are quite complicated. Depending on the powder used, they require more or less extensive cleaning and are susceptible to contamination, rust and lack of oil due to the many sliding parts. A saving of the gas piston by applying the closure with tapped powder gases leads to a structural simplification, but an increased risk of contamination.
  • the application discloses a self-loading handgun, wherein as in the aforementioned generic self-loading handgun between the closure carrier and closure a strong spring assembly is arranged over which the (heavy) closure carrier is supported on the latter with the locking head. In addition to the spring arrangement but there is no stop between the closure head and closure carrier, so that the initial relative movement between these parts is not limited by a stop.
  • the lock head is locked against the barrel then the gun is closed.
  • the lock is, as usual, only solvable when the closure carrier has moved from this position by a piece to the rear.
  • the closer moving rear closure carrier now takes the closure head with the rear.
  • a cartridge is inserted into the chamber.
  • the closure head beats on the cartridge bottom or chamber and comes to a standstill.
  • the occlusive carrier opening onto the closure head locks the closure head in relation to the barrel and then also comes to a standstill.
  • closing spring assembly which may also consist of several springs.
  • the weapon When shooting (from the shoulder or from the hip), the weapon performs a short, powerful backwards movement, which is felt by the shooter as a recoil. Also, all parts that are then stationary relative to the weapon as a whole, so the fixed barrel and the locked closure head, follow this recoil movement.
  • the shutter carrier does not follow the recoil movement but, due to its inertia, initially remains in its absolute position, which is in contrast to the usual practice. That is, as a result of the recoil, the barrel and the closure head move rearwardly relative to the closure carrier, against the force of the strong spring assembly; possibly supported by the much weaker closing spring. When viewed from the barrel, barrel and lock head remain stationary. The shutter carrier moves relative to these forward and is limited by the spring assembly.
  • the spring arrangement act directly or even indirectly between the closure carrier and the closure head and therefore can be supported on any other, brought into stationary contact with the closure head part of the weapon.
  • the compressed spring assembly After stopping the relative movement, the compressed spring assembly begins to expand again, and hurls the closure carrier against the force of the closing spring back powerful. In the course of its backward movement, the closure carrier unlocks the closure head from the barrel and then takes him backwards. It is thus completed an opening cycle of the loading movements.
  • the more compressed spring arrangement throws the closure carrier more violent than a weak cartridge only weakly compressed spring arrangement. Therefore, with a strong cartridge, the shutter carrier will also make the opening of the shutter head and the extraction of the cartridge case faster than with a weak cartridge. In the case of shotgun cartridges, this is harmless in itself, since the thicker shotgun cartridges are also more modern cartridges, which better withstand the loads than weaker cartridges with cardboard. When exceeding or falling below a certain speed range of the closure carrier but the speed frame is left, is expected on the one hand with safe closure function and on the other hand with reliable undressing. This is possibly even the durability of the weapon at risk.
  • a particularly violent opening of the closure is to be expected when the spring assembly is previously completely compressed, so that the gears of the spring, in particular the coil spring, rest on each other. Then, the opening speed can be increased in an unforeseen manner. In addition, parasitic vibrations can superimpose and disturb the system. Again, the durability of the weapon is a critical feature.
  • the spring arrangement of the compression opposes a progressively increasing force.
  • the lower limit of the said speed range and thus the interpretation of the suspension is chosen so that even weak cartridges and pollution is expected to have a reliable function.
  • the force of the spring assembly does not increase linearly under load, but progressively, and to such an extent that the spring assembly can not be significantly compressed even when shooting strongest cartridges. With the above disturbance must therefore not be expected.
  • An optimized spring characteristic can be achieved for example by a kind of disc spring stack. Cheaper and easier, however, it is to equip the spring assembly with a strong spring with a substantially linear force-displacement characteristic and additionally provide a buffer arrangement, which is only charged after the spring has been partially compressed. In this case, the spring and the Pufferanordung can be coordinated so that when you shoot weak cartridges only the spring is loaded and expands again, the firing of a stronger cartridge, however, in addition, the buffer assembly.
  • the buffer arrangement can ensure the desired, progressive behavior with simple means.
  • a buffer arrangement of at least one stack of elastomer buffers with high hysteresis has proved to be optimal.
  • the stack arrangement ensures that the buffer assembly can be easily adapted to strong cartridges.
  • elastomeric buffers tend to deflect under load, across the load and thus increase their diameter.
  • the degree of increase in diameter is a function of the length of the buffer so that several stacked, short buffers increase in diameter less than a single, long buffer.
  • Hysteresis buffers provide for a reduction and phase shift of the returned spring force. So it is ultimately possible, even for strongest cartridges the above speed range, within which the shutter is working properly to comply reliably.
  • cartridges of caliber 12 i. about such different sleeve lengths, about 70 mm and 76 mm long cartridges to shoot properly.
  • By simply adjusting the spring and the buffer device even cartridges of caliber 12/65 or 12/89 can be mixed shot, if this should not be possible anyway with a standard vote.
  • firing pin is mounted directly on the closure head.
  • the cartridge could be ignited if the closure head still rests on the cartridge, regardless of whether the shutter is locked or unlocked.
  • a locking block is assigned to the closure head, which is traversed freely in a locking position of the firing pin and locks in an unlocked position the firing pin in a retracted, inoperative position (claim 8).
  • the locking block thus acts as a sort of backup, because the trigger can only ignite the cartridge when the lock head is locked.
  • This embodiment is further improved in that the locking block has a chamfer, with which he takes the firing pin in the inoperative position in the transition from the locked to the unlocked position. If, for example, as a result of a cartridge error, the firing pin gets caught in the primer during the shot, then it is released from the locking block by its movement when unlocking and spent in an ineffective position.
