Description

Die Erfindung handelt von Gasdruckpistolen, wobei es sich sowohl um Luftdruck- als auch um CO-2-Pistolen handeln kann, wie sie für sportliche Wettbewerbe eingesetzt werden.The invention relates to gas pressure pistols, which can be both air pressure and CO-2 pistols as are used for sporting competitions.

Naturgemäß kommt es bei Wettbewerben auf höchste Präzision an. Dazu ist es erwünscht, die Reaktion der Waffe beim Schuß möglichst gering zu halten und die vom Reglement festgelegte maximale Visierlänge voll auszunutzen.Naturally, the highest precision is important in competitions. For this purpose, it is desirable to keep the weapon’s reaction when firing as low as possible and to take full advantage of the maximum sight length specified by the regulations.

Aus Gründen der Treffergenauigkeit verbietet sich die Vorverlegung des Kornes vor die Laufmündung, weil dadurch in den nach dem Geschoß aus dem Lauf austretenden Gasschwall Turbulenzen auftreten und das Geschoß ablenken würden. Dabei ist zu bedenken, daß dieser Gasschwall bei Gasdruckwaffen durch die grundsätzlich anderen thermodynamischen Verhältnisse viel empfindlicher ist.For the sake of accuracy, it is forbidden to advance the grain in front of the barrel muzzle, because this would cause turbulence in the gush of water emerging from the barrel after the projectile and would deflect the projectile. It should be borne in mind that this gas surge is much more sensitive to gas pressure weapons due to the fundamentally different thermodynamic conditions.

Bei Feuerwaffen ist es zwar bekannt, durch verschiedene Mündungsbremsen die Reaktionskräfte zu vermindern, doch steht dabei die Verminderung des Rückstoßes im Vordergrund. Bei Faustfeuerwaffen ist das reaktionsbedingte Kippmoment so groß, daß Mündungsbremsen keine vollständige Abhilfe schaffen.In the case of firearms, it is known to reduce the reaction forces by means of various muzzle brakes, but the focus is on reducing the recoil. With handguns, the reaction-related tipping moment is so great that muzzle brakes do not provide a complete remedy.

So ist etwa aus der US-A 4,691,614 eine Feuerwaffe mit Kompensator bekannt, der von einer Kammer mit Schlitzen gebildet wird, deren Länge mehr als das Dreifache des Kalibers beträgt, um den Gasen ein Überholen des Geschoßes zu ermöglichen. Das führt zu einer starken Turbulenz in der Kammer und zu einem stark wirksamen Ausgleich des Rückstoßes in Schußrichtung.For example, a firearm with compensator is known from US-A 4,691,614, which is formed by a chamber with slots the length of which is more than three times the caliber to allow the gases to overtake the projectile. This leads to a strong turbulence in the chamber and to a highly effective compensation of the recoil in the firing direction.

Weiters ist aus der CH-A 237415 eine Rücklaufbremse für Feuerwaffen bekannt, bei der die Kammer über teils sogar rückwärts geneigte Bohrungen mit der Umgebung verbunden ist. Auch hier steht der Ausgleich des Rückstosses im Vordergrund, ein turbulenzfreier seitlicher Abzug der Gase durch die Bohrungen ist nicht gegeben.Furthermore, a return brake for firearms is known from CH-A 237415, in which the chamber is connected to the surroundings via bores which are sometimes inclined backwards. Here, too, the focus is on compensating for the recoil; there is no turbulence-free lateral extraction of the gases through the holes.

Schließlich ist noch aus der US-A 4,322,999 ein Laufstabilisator für Feuerwaffen bekannt, der überhaupt keine Kammer und ein Kanalsystem mit Kanälen geringen Querschnittes aufweist, also für Druckgaswaffen überhaupt nicht brauchbar ist.Finally, from US-A 4,322,999 a barrel stabilizer for firearms is known which has no chamber at all and a channel system with channels of small cross-section, that is to say it is not usable at all for pressurized gas weapons.

Es ist daher Ziel der Erfindung, eine gattungsgemäße Pistole so zu verbessern, daß bei verminderter Ablenkung des Geschoßes durch Gaswirbel oder durch Reaktionsbewegungen bei gleichbleibender Lauflänge der Waffe die Visierlänge vergrößert werden kann.It is therefore an object of the invention to improve a generic pistol such that the sight length can be increased with reduced deflection of the projectile by gas eddies or by reaction movements while the barrel length remains the same.

Erfindungsgemäß ist (sind) bei einer Gasdruckpistole, bei der an das vordere Laufende, eine Kammer anschließt, die von einer Umfangswand mit mindestens einer nach oben gerichteten Öffnung und einem vorderen Endstück mit einer Durchtrittsbohrung für das Geschoß gebildet wird und auf der Umfangswand das Korn angeordnet ist, die mindestens eine Öffnung in der Umfangswand (ein) längsgerichtete(r) Schlitz(e) und ragt das vordere Endstück mit einem konisch verjüngten Teil ins Innere der Kammer, wobei die Entfernung zwischen der Innenkante des konisch verjüngten Teiles und der Laufmündung etwa so groß wie das Kaliber des Geschoßes ist.According to the invention is (are) in a gas pressure gun, in which at the front barrel end, a chamber is formed, which is formed by a peripheral wall with at least one upward opening and a front end piece with a through hole for the projectile and the grain is arranged on the peripheral wall is the at least one opening in the peripheral wall (a) longitudinal slot (s) and protrudes the front end piece with a conically tapered part into the interior of the chamber, the distance between the inner edge of the conically tapered part and the barrel muzzle approximately so as big as the caliber of the bullet.

Durch die von Umfangswand und Endstück gebildete Kammer mit nach oben gerichteter Öffnung wird dem Kippmoment durch Ablenkung des Gasschwalles nach oben entgegengewirkt, wobei das Endstück Rückwirkungen des abgelenkten Gasschwalles auf das Geschoß verhindert. Durch die Anordnung des Kornes auf der Umfangswand wird eine Vergrößerung der Visierlänge erreicht, ohne daß dieser Vorteil mit Turbulenzen des Gasschwalles erkauft werden müßte.Through the chamber formed by the peripheral wall and the end piece with the opening pointing upwards, the tilting moment is deflected of the gas surge counteracted upwards, the end piece preventing reactions of the deflected gas surge on the projectile. By arranging the grain on the peripheral wall, the length of the sight is increased without this advantage having to be bought with turbulence of the gas surge.

Dadurch, daß die mindestens eine Öffnung in der Umfangswand ein längsgerichteter Schlitz ist und das Endstück mit einem konisch verjüngten Teil ins Innere der Kammer ragt, wird ein besonders günstiger Strömungsverlauf in der Kammer erreicht, weil der Gasschwall durch den konisch verjüngten Teil bei einem Minimum an Verwirbelung umgelenkt wird und durch die Schlitze über die ganze Länge der Kammer austreten kann.Characterized in that the at least one opening in the circumferential wall is a longitudinal slot and the end piece with a conically tapered part protrudes into the interior of the chamber, a particularly favorable flow pattern in the chamber is achieved because the gas surge through the conically tapered part at a minimum Whirl is deflected and can escape through the slots over the entire length of the chamber.

Durch die Wahl der Entfernung zwischen der Innenkante des konisch verjüngten Teiles und der Laufmündung etwa so groß wie das Kaliber, werden Rückwirkungen des Gasschwalles auf das Geschoß minimiert.By choosing the distance between the inner edge of the conically tapered part and the barrel muzzle approximately as large as the caliber, the effects of the gas surge on the projectile are minimized.

In Weiterbildung der Erfindung ist die Vorderkante der Schlitze vorwärts geneigt, wodurch die Strömung in der Kammer weiter vergleichmäßigt und das Gegenmoment erhöht werden.In a further development of the invention, the front edge of the slots is inclined forward, as a result of which the flow in the chamber is further equalized and the counter moment is increased.

In einer Ausführungsform der Erfindung ist die Umfangswand auf das Laufende aufgesteckt und ihr vorderes Ende weist dieselben Befestigungsmittel für das Korn auf wie der Lauf. In dieser Form kann die Erfindung auf eine bereits vorhandene Pistole angewendet werden, ohne daß an der Pistole selbst irgendwelche Veränderungen vorgenommen werden müßten.In one embodiment of the invention, the peripheral wall is attached to the barrel end and its front end has the same fastening means for the grain as the barrel. In this form, the invention can be applied to an existing pistol without any changes to the pistol itself.

In einer anderen Ausführungsform verfügt die Pistole über einen Laufmantel und die Umfangswand ist Teil des Laufmantels. In dieser Form wird zwar ein anderer Laufmantel benötigt, doch bleiben alle anderen Teile der Pistole unverändert.In another embodiment, the gun has a barrel jacket and the peripheral wall is part of the barrel jacket. A different barrel jacket is required in this form, but all other parts of the pistol remain unchanged.

In den Figuren 1,2 und 3 ist von einer ersten Ausführungsform der erfindungsgemäßen Pistole nur der vordere Teil des Laufes 1 mit der erfindungsgemäßen Vorrichtung und symbolisch das Hinterteil des Gehäuses 26 mit der Kimme 24 dargestellt. Der Lauf 1 verfügt an seinem vorderen Ende über eine Eindrehung 2, auf der ein Laufvorsatz 3 aufgesteckt und befestigt ist, wobei die Befestigung in beliebiger Weise erfolgen kann. Dieser Laufvorsatz 3 besteht aus einer Umfangswand 4 und einem in deren vorderen Teil eingesetzten Endstück 5. Dieses weist eine innere Durchtrittsbohrung 6 für das Geschoß 14 auf, deren Durchmesser daher etwas größer als das Kaliber des Geschoßes, ist und einem nach innen ragenden konischen Innenteil 7. Das Endstück 5 bildet mit der Umfangswand 4 eine Kammer 8 und ist beispielsweise mittels einer Wurmschraube 9 gegenüber der Umfangswand 4 festgelegt, könnte aber auch eingepreßt oder in anderer Weise auch verstellbar mit dieser verbunden sein.In FIGS. 1, 2 and 3, of a first embodiment of the pistol according to the invention, only the front part of the barrel 1 with the device according to the invention and the rear part of the housing 26 with the rear sight 24 are symbolically represented. The barrel 1 has at its front end a recess 2 on which a barrel attachment 3 is attached and fastened, the fastening being able to be carried out in any manner. This barrel attachment 3 consists of a peripheral wall 4 and an end piece 5 inserted in its front part. This has an inner through bore 6 for the projectile 14, the diameter of which is therefore somewhat larger than the caliber of the projectile, and an inwardly projecting conical inner part 7 The end piece 5 forms a chamber 8 with the peripheral wall 4 and is fixed relative to the peripheral wall 4, for example by means of a worm screw 9, but could also be pressed in or connected in an adjustable manner in some other way.

Im oberen Teil der Umfangswand 4 sind zwei Längsschlitze 10,11 angeordnet, deren zu einer vertikalen Längsebene symmetrische Winkelstellung in Fig.3 erkennbar ist. Die Vorderkanten 12 dieser Längsschlitze sind, siehe Fig.4, vorwärts geneigt, die Hinterkanten 13 sind es nicht, könnten es aber auch sein.In the upper part of the peripheral wall 4, two longitudinal slots 10, 11 are arranged, the angular position of which is symmetrical with respect to a vertical longitudinal plane can be seen in FIG. The front edges 12 of these longitudinal slots are inclined forward, see FIG. 4, the rear edges 13 are not, but could also be.

Durch diese Gestaltung des Laufvorsatzes 3 wird der aus dem Lauf 1 austretende Gasschwall zuerst durch den konischen Innteil 7 weitgehend turbulenzfrei aufwärts umgelenkt und tritt sodann durch die Schlitze 10, 11 aus. Wenn diese Umströmung voll ausgebildet ist, befindet sich das Geschoß 14 (beispielsweise ein Diabolo-Geschoß) bereits in der Durchtrittsbohrung 6 und kann daher durch den Gasschwall nicht mehr abgelenkt werden. Der Verlauf der Strömung ist durch die Pfeile 15 angedeutet. Die Umlenkung erzeugt das Gegenmoment, das das Kippmoment teilweise bis ganz aufhebt.As a result of this design of the barrel attachment 3, the gas surge emerging from the barrel 1 is first deflected upward through the conical inner part 7 largely without turbulence and then emerges through the slots 10, 11. If this flow is fully developed, the projectile 14 (for example a diabolo projectile) is already in the through bore 6 and can therefore no longer be deflected by the gush of gas. The course of the flow is through the arrows 15 indicated. The deflection creates the counter moment, which partially or completely eliminates the overturning moment.

Am vorderen Teil des Laufvorsatzes 13 ist beispielsweise wieder ein Absatz 20 vorgesehen, dessen Durchmesser gleich dem der Eindrehung 2 ist. Auf diesen ist der Kornring 21 mit Korn 22 aufgesteckt und in geeigneter Weise, beispielsweise mit einer Wurmschraube 23 befestigt. Der Laufvorsatz 3 ist aufsteckbar. Strichliert ist der Kornring 21 und das Korn 22 in den Stellungen 21′, 22′ angedeutet in der Stellung, in der sie sich bei nicht aufgestecktem Laufvorsatz befinden.At the front part of the barrel attachment 13, for example, a shoulder 20 is again provided, the diameter of which is equal to that of the recess 2. The grain ring 21 with grain 22 is attached to it and fastened in a suitable manner, for example with a worm screw 23. The barrel attachment 3 can be plugged on. Dashed line is the grain ring 21 and the grain 22 in the positions 21 ', 22' indicated in the position in which they are when the barrel attachment is not attached.

In der dargestellten Ausführungsform kann somit bei einer Gasdruckpistole nach dem Stand der Technik der Kornring 21 abgenommen, der Laufvorsatz 3 aufgesteckt und der Kornring 21 wieder auf den Laufvorsatz aufgesteckt werden. Die Visierlänge 27,27′, - der Abstand zwischen dem am hintersten Ende des Pistolengehäuses 26 über eine nur angedeutete Einstellvorrichtung 25 befestigten Kimme 24 und dem Korn 22 - wird durch Aufstecken des Laufvorsatzes von 27′ auf 27 erhöht.In the embodiment shown, the grain ring 21 can thus be removed from a gas pressure gun according to the prior art, the barrel attachment 3 can be attached and the grain ring 21 can be attached again to the barrel attachment. The sight length 27.27 ', - the distance between the rear end of the gun housing 26 via an only indicated adjusting device 25 fixed rear sight 24 and the grain 22 - is increased by attaching the barrel attachment from 27' to 27.

Das Korn könnte aber auch, ähnlich wie in Fig.5, nur auf den Lauf 1 aufgeschraubt sein, dann hätte auch der Laufvorsatz 3 eine identische Befestigungsanordnung für das Korn 22.However, the grain could also be screwed onto the barrel 1, similarly as in FIG. 5, in which case the barrel attachment 3 would also have an identical fastening arrangement for the grain 22.

In den Figuren 5 und 6 ist eine andere Ausführungsform der Erfindung dargestellt, die sich von der ersten Ausführungsform vorerst dadurch unterscheidet, daß der Lauf 30 von einem Laufmantel 31 umgeben ist, der die Laufmündung 37 überragt und somit selbst die Umfangswand 32 bildet.Another embodiment of the invention is shown in FIGS. 5 and 6, which differs from the first embodiment in that the barrel 30 is surrounded by a barrel jacket 31 which projects beyond the barrel mouth 37 and thus itself forms the peripheral wall 32.

In diese ist dann, wie die zu den Fig. 1 bis 4 beschrieben, ein Endstück 33 mit konischem Innenteil 34 befestigt. Die zwischen Umfangswand 32, Endstück 33 und Laufmündung 37 gebildete Kammer 36 steht auch wieder über Schlitze 35 mit der Umgebung in Verbindung.An end piece 33 with a conical inner part 34 is then fastened into this, as described for FIGS. 1 to 4. The chamber 36 formed between the peripheral wall 32, the end piece 33 and the barrel mouth 37 is again provided with slots 35 the surrounding area.

Der Laufmantel 31 weist oben eine Abflachung 38 auf, auf der ein Korn 39 mittels einer Kornschraube 40 angeschraubt ist. Strichliert und mit 39′, 40′ bezeichnet sind beide Teile auf einer Pistole mit Laufmantel nach dem Stand der Technik abgebildet. Die Visierlänge erhöht sich somit von 41′ auf 41.The barrel jacket 31 has a flat surface 38 on which a grain 39 is screwed by means of a grain screw 40. Dashed and designated 39 ', 40', both parts are shown on a pistol with a barrel jacket according to the prior art. The length of sight thus increases from 41 'to 41.

Schließlich ist in Fig. 6 erkennbar, daß der Laufmantel 31, der im allgemeinen aus extrudiertem oder gespritzten Leichtmetall besteht, oben die Abflachung 38 für das Korn und unten eine Einbuchtung 43 aufweist, die Raum für den strichliert angeangedeuteten Druckgasbehälter 42 schafft.Finally, it can be seen in Fig. 6 that the barrel jacket 31, which generally consists of extruded or injection-molded light metal, has the flattened area 38 for the grain and an indentation 43 below, which creates space for the compressed gas container 42 indicated by the broken line.
