Definitions

  • the invention relates to a self-loading handgun.
  • the above-mentioned generic weapon is a so-called "shooting weapon", ie a weapon in which the breech is in its closed position when the trigger is actuated to fire a shot.
  • Such a weapon usually has a breech catch device.
  • a breech catch device holds the closure in its almost open position when the magazine is empty.
  • Closure catchers have been known since the beginning of the century. Its original purpose was to allow the magazine, which was mounted in the weapon, to be loaded past the open breech. Later, in the case of weapons with a removable magazine, the open breech served as an indication for the Protect that there is no cartridge left in the weapon; also to shorten the time required for reloading. After insertion of a new, full magazine, the breech has to be reloaded only slightly and then released, or the breech catch device can be switched off by operating a handle on the outside of the weapon. The breech closes automatically and takes the top cartridge out of the new magazine so that the weapon is ready to fire.
  • the breech closes automatically and takes the top cartridge out of the new magazine so that the weapon is ready to fire.
  • switch-off direction The direction in which the handle must be actuated to switch off the breech stop device is hereinafter referred to as the "switch-off direction".
  • the breech lock or catch device also has the function of keeping the breech open even at shooting ranges, in accommodations and par excellence when handling the weapon, so that it can be seen from a distance that the weapon is not ready to fire. The magazine is then also removed from the weapon.
  • Closure catcher which then keeps the closure open. If the lock catch device is additionally equipped with the above-mentioned handle, this could in principle also be operated - with the lock retracted - against the switch-off direction defined above and the lock left again a little forward. It is then held in place by the breech catcher. In practice, however, the empty magazine is used regularly, not the handle for switching on the
  • a large-caliber self-loading rifle system can certainly fire grenades, i.e. explosive projectiles with considerable explosive power.
  • Such explosive projectiles are normally detonated only at an adjustable safety distance from the weapon and the gunner.
  • an explosive projectile that has been fired will detonate beforehand, for example if it encounters a hard obstacle close to the muzzle.
  • Trigger device before, the shooter must ensure that he does not accidentally fire the large-caliber self-loading rifle system when he actually wants to shoot with the rapid-fire rifle system. Such incorrect operation can occur, for example, in that the shooter incorrectly set the trigger device or the setting thereof has been changed by external influences, for example when crossing brushes of grazing branches. If the shooter actually wants to shoot with the large-caliber rapid-fire rifle system, all he has to do is operate the handle mentioned in the switch-off direction. The breech then moves to its forward position and the weapon is ready to fire.
  • the handle will also be actuated unintentionally or unnoticed in the switch-off direction, so that the breech catcher releases the breech without the shooter noticing this; such as when the shooter is forced to seek cover quickly, throws himself on the ground with his weapon and the handle hits an obstacle in such a way that it switches off the breech stop.
  • the large-caliber self-loading rifle system is ready to fire without the shooter being aware of it; at least as long as he does not check the condition of his weapon or overlooks the incorrect setting with excitement.
  • the invention is intended to remedy this problem. It is intended to develop the hand-held self-loading weapon mentioned at the outset in such a way that, while maintaining its essential advantages for improving safety, it largely precludes inadvertent release of the breech locked by the breech block.
  • Control can be turned on, but not turned off. It only switches off automatically when the lock is pulled back.
  • the purpose is to reload the box magazine, which cannot be removed from the weapon for reloading, but has to be reloaded past the open breech from above.
  • the breech lock is also operated as usual from the empty magazine, but not if there is still a cartridge left in the magazine. Only by means of the Operating element, it is possible to keep the breech open when the rifle is only partially unloaded, so that the magazine can be refilled.
  • Closure must not be lifted because the handle is not set up for such a function. External forces could also act on the loading lever. But even they are not sufficient to retract the closure against the force of the almost fully tensioned closing spring to such an extent that the closure lock is switched off.
  • the handle as a momentary switch in accordance with a preferred development of the invention, which means that the handle only remains in its position which switches on the catch direction as long as it is actuated (claim 2). As soon as the actuation is released, the handle automatically returns to its ineffective position. Thus, even during a shot, locking of the breech is extremely unlikely if a branch or other external obstacle inadvertently actuates the handle. Because of the strong vibration that occurs when the shot is fired, the weapon is always clear of such an obstacle before the breech can reach the breech catcher on return.
  • the shooter by clumsiness or excitement, actuates the handle when firing the shot and inadvertently brings about the locking of the breech, for example because he has gripped the rifle incorrectly or inappropriately in his haste.
  • a further development of the invention prevents this danger as follows: the handle is arranged at a point on the weapon where it is not in the hands of the shooter can be achieved during the shot (claim 3). The handle is located far enough away from the handle and the forearm, i.e. the parts on which the rifle hands are located during the shot. Even an inaccurate grasping of the weapon does not allow the accidental actuation of the handle and activation of the breech catcher.
  • the handle is preferably designed as a push button, which can preferably be pressed resiliently transversely to the firing direction into the weapon housing in order to switch on the breech catch device (claim 4).
  • the handle can be easily operated with the trigger hand of the shooter, while the other hand pulls the lock back by means of the loading lever and then lets it rest on the activated lock.
  • the shooter's hand should always be used to operate the loading lever, which does not include the handle and actuates the trigger.
  • the hand gripping the grip piece must release its grip and actuate the handle.
  • Now modern rifles are set up so that they can be used not only by right-handers, but also by left-handers in the same way.
  • the loading lever on these weapons can be operated with the left hand as well as with the right hand. This is always the case with a central loading lever; in the case of a side loading lever if the shooter can implement it so that it can be gripped on the left (right-hander) or right (left-hander) side of the weapon housing.
  • a handle is preferably provided on each side of the weapon housing with which the breech catch device can be switched on (claim 5).
  • the handle is designed as a swivel lever, swivel levers attached to both sides of the housing can be coupled to one another in a simple manner by means of a transverse shaft; with a push button as a handle, however, the coupling appears much more difficult because the two push buttons do not have to be actuated synchronously, but in opposite directions to switch on the lock catch device.
  • the invention provides a surprisingly simple solution.
  • the handle which can be actuated on both sides, has an axis passing through the weapon housing, which axis can be moved in both longitudinal directions from a middle rest position into an end position and the ends of which are each designed as push buttons.
  • This axis is coupled to the lock catcher in such a way that it switches on the lock catcher in one of the end positions (claim 6).
  • Each push button is on its side so far out of the weapon housing that the axis can be brought into an end position by pressing the respective push button.
  • the coupling to the lock catcher can be done, for example, by a tension member that is tensioned by the movement of the axis, in whatever direction, and then in turn pulls an element of the lock catcher into an effective position.
  • a control cam or a control link is preferably arranged or formed on the axle, which forms a symmetrical control cam and engages in the locking catch device as follows: in the middle, idle position of the axis, the center of the control curve lies opposite a movable switching element of the lock catch device, leaves this unactuated and allows him the unimpeded execution of one initiated by the feeder of the magazine Switch-on movement. If, however, the axis is brought into one of its two end positions, the control cam acts on the movable element and switches on the locking catch device.
  • two compression springs are provided, both of which are seated one behind the other on the axle, are supported with their ends facing away from one another on a projection of the axle, and are supported with the mutually facing ends on a counter bearing which is arranged in the housing and is penetrated by the axle (Claim 8). Both springs keep the axle in a neutral position, whereby they are equally tensioned against each other.
  • axle If the axle is pressed in by means of a push button formed at its end, one of the springs is relieved and the other is loaded even more. This more heavily loaded spring returns the axis to its neutral position or equilibrium position after releasing the push button. In this position, both springs are loaded equally.
  • the breech catch device has a switching finger which preferably engages over the front of the magazine at a point which cannot be reached by the bullet tips of the cartridges located in the magazine. If the feeder of the magazine has moved the last cartridge upwards, then it displaces or pivots the shift finger, which thereby switches on the breech catch device. The latter then retains the breech in its open position, into which it had returned due to the firing of this last cartridge.
  • the shift finger is connected by a linkage or the like to a pawl or the like which engages in the locking path.

Finally, pivoting the catch pawl 17 clockwise would lock 5, i.e. move against the force of its return spring.

Abstract

L'invention concerne une arme portative à chargement automatique comportant un mécanisme de retenue de culasse qui peut être actionné par l'élément d'alimentation d'un chargeur vide et qui maintient la culasse dans une position pratiquement ouverte lors de son mouvement de recul. Ce mécanisme de retenue de culasse présente au moins un organe d'actionnement (poussoirs 23, 25) qui, contrairement à la technique antérieure, ne peut pas être actionné pour désenclencher le mécanisme de retenue de culasse mais exclusivement pour enclencher ce dernier. L'invention vise à créer un organe d'actionnement pouvant être actionné aussi facilement par un droitier que par un gaucher. A cet effet, le boîtier (31) de l'arme à feu est traversé par un arbre (21) qui, à chacune de ses extrémités, se présente sous la forme d'un poussoir (23, 25), est maintenu dans une position neutre par des ressorts (27, 29) placés l'un contre l'autre, à l'intérieur du boîtier (31), comporte une came de commande (35), et est placé avec cette dernière de manière opposée au mécanisme de retenue de culasse de sorte que la came de commande (35) vient en contact avec le mécanisme de retenue de culasse et enclenche ce dernier uniquement si l'un des poussoirs (23, 25) est enfoncé en direction du boîtier (31) et aussi longtemps que ce poussoir reste dans cette position.
