Abstract

Methods and apparatus are described for gas cylinder components for use with a firearm with a barrel. The gas cylinder component includes a reception bore for receiving the barrel. Additionally, the gas cylinder component includes a torque-proof fixture that is under pre-stressing, wherein the torque-proof fixture comprises one or more bores tangential to the barrel further including a pin to create spring pinning action. Further, the gas cylinder component includes a foresight that is rotatable around an axis, and a demountable clamping device that secures at least one position of the foresight. The gas cylinder component is under spring pre-stressing and is torque proof on the barrel. Additionally, the gas cylinder component is to lock on the barrel. Further, the engagement of the gas cylinder component on the barrel is to substantially prevent the rotation of the gas cylinder apparatus relative to an axis of the barrel. Further yet, substantially all forces that are introduced to a front of the firearm is absorbed by the gas cylinder component and introduced into the barrel.

Description

Die Erfindung betrifft das Gaszylinderbauteil mit einer Aufnahmebohrung für einen Lauf, das, genauer gesagt, zu einer Selbstlade-Handfeuerwaffe gehört. Die Erfindung bezieht sich auch auf eine Handfeuerwaffe mit einem erfindungsgemäßen Gaszylinderbauteil .The invention relates to the gas cylinder component with a receiving bore for a barrel, which, more specifically, belongs to a self-loading handgun. The invention also relates to a handgun with a gas cylinder component according to the invention.
Lagebezeichnungen wie „oben" oder „rechts" beziehen sich auf eine Handfeuerwaffe, die in normaler Schußposition gehalten wird, also mit horizontaler Seelenachse (Achse des Laufes) und mit nach unten weisendem Griff, aus der Position des Schützen gesehen. „Vorn" liegt demnach die Mündung, während sich die Schaftkappe „hinten" befindet. Im folgenden werden außerdem unter „Gewehr" auch Maschinenpistolen o. dgl . verstanden, besonders, soweit sie zur Benutzung mit zwei Händen eingerichtet sind.Location names such as "up" or "right" refer to a handgun held in the normal firing position, that is, with the horizontal axis of the bore (axis of the barrel) and with the handle down, as seen from the shooter's position. "Front" is therefore the mouth, while the butt plate is "back". In the following also "gun" and submachine gun o. The like. Understood, especially if they are set up for use with two hands.
In Zusammenhang mit der Erfindung sind die DE 1 453 904 A, US 1 350 961, DE 103 18 828 Al und DE 29 32 710 Al bekannt geworden.In connection with the invention, DE 1 453 904 A, US Pat. No. 1 350 961, DE 103 18 828 A1 and DE 29 32 710 A1 have become known.
Bei modernen Schnellfeuergewehren sitzt der Gaszylinder in aller Regel über dem Lauf, um den Mechanismus zum Zuführen der Patronen nicht zu beeinträchtigen. Die Visierlinie liegt noch weiter über dem Lauf, was in der Regel erwünscht ist, damit die Richtung des Rückstoßes genau in Richtung der Schulter verläuft und nicht oberhalb deren, wie es zum Beispiel bei Militärgewehren aus dem Anfang des 20. Jahrhunderts und bei Jagdgewehren die Regel ist.In modern rapid-fire guns, the gas cylinder usually sits over the barrel so as not to interfere with the cartridge feeding mechanism. The line of sight is even further over the barrel, which is usually desirable so that the direction of the recoil runs exactly in the direction of the shoulder and not above it, as is the case, for example, with military rifles from the beginning of the 20th century and with hunting rifles is.
Da bei Schnellfeuergewehren, etwa dem AK 74, der Gaszylinder meist nicht ganz an der Mündung angebracht ist, man aber eine möglichst lange Visierlinie bewahren will, sitzt zusätzlich auf der Mündung noch ein Visierfuß. Dies ist aufwendig, denn der Visierfuß darf nicht wackeln und muß auch einen kräfigen Schlag hinnehmen, ohne sich zu verschieben oder zu verbiegen. Aber auch Gaszylinder sollte möglichst stramm und unverrückbar auf dem Lauf sitzen. Beim Gaszylinder sind allerdings gewisse Toleranzen möglich, so lange die Bohrungen im Lauf und im Gaszylinder aufeinandertreffen, weswegen meist eine der Bohrungen größer gewählt ist als die andere.As in rapid-fire guns, such as the AK 74, the gas cylinder is usually not quite attached to the muzzle, but one wants to preserve as long as possible line of sight, sitting additionally on the mouth nor a Visierfuß. This is expensive, because the visor foot must not wobble and must also take a strong blow without moving or bending. But also gas cylinder should sit as tight and immovable on the barrel. With the gas cylinder, however, certain tolerances are possible as long as the holes in the barrel and in the gas cylinder meet, which is why one of the holes is usually chosen to be larger than the other.
Außerdem weist ein Schnellfeuergewehr noch Halterungen für den Handschutz auf. Oft sind auch Halterungen für einen Granatwerferzusatz o. dgl . vorgesehen. Soweit am Handschutz Halterungen für Zusatzeinrichtungen etwa im Form einer Picatinny-Schiene ausgebildet sind, sollte auch der Handschutz zur Seelenachse zumindest immer parallel sein.In addition, a rapid-fire rifle still holds for hand protection. Often also holders for a grenade launcher addition o. The like. intended. As far as handguards for accessories are formed approximately in the form of a Picatinny rail, and the hand guard should be at least always parallel to the axis of the soul.
Bei Verwendung von zusätzlichen, optischen und/oder elektronischen Zieleinrichtungen tritt ferner das Problem auf, daß deren optische Achse auf das Visier trifft, soweit man nicht eine Visierlinie für Visier oder Zieleinrichtung wählt, die nicht körpergerecht für den Schützen ist und deshalb auch nicht optimal genutzt werden kann. Zwar sind schon Klappvisiere bekannt, die durch Umklappen die Visierlinie freimachen (Schweizer Sturmgewehr 57), aber diese Klappvisiere dienen der Marscherleichterung und haben sich nicht bewährt, da sie in jedem Fall vor dem Gebrauch des Gewehres aufgeklappt werden müssen und somit zusätzliche Zeit benötigen, wenn man nicht auf die Marscherleichterung verzichten will oder einen ungezielten Schuß abgibt.When using additional, optical and / or electronic target devices, there is also the problem that their optical axis is incident on the visor, unless one selects a sighting or sighting line of sight, which is not appropriate for the shooter and therefore not used optimally can be. Although folding visors are already known to clear the visor line by folding (Swiss assault rifle 57), but these folding visors serve the Marscherleichterung and have not been successful, since they must be opened in any case before the use of the rifle and thus need extra time, if you do not want to give up the Marscherleichterung or give off an untargeted shot.
Ausgehend von dieser Problemlage liegt der Erfindung die Aufgabe zugrunde, ein Gaszylinderbauteil so auszubilden, daß die obigen Probleme mindestens teilweise gemindert werden können. Insbesondere ist eine zuverlässige, aber wenig aufwendige Lösung anzustreben.Based on this problem, the invention has the object, a gas cylinder component in such a way that the above problems are at least partially mitigated can. In particular, a reliable, but less expensive solution is desirable.
Das erfindungsgemäße Gaszylinderbauteil löst diese Aufgabe dadurch, daß es derart ausgestaltet ist, daßThe gas cylinder component according to the invention solves this problem in that it is designed such that
- es so in den Lauf eingreift, daß deren relative Drehung verhindert ist, bezogen auf die Seelenachse,it engages in the barrel so that its relative rotation is prevented with respect to the axis of the soul,
- es zusätzlich drehfest unter Vorspannung am Lauf gehaltert ist, - wobei ein um eine Querachse klappbares Korn auf dem Gaszylinderbauteil vorgesehen ist, und eine lösbare Klemmeinrichtung den strammen Halt des klappbaren Korns zumindest in seiner aufrechten Lage gewährleistet .- It is additionally rotatably supported under bias on the barrel, - wherein a foldable about a transverse axis grain is provided on the gas cylinder component, and a releasable clamping device ensures the tight grip of the hinged grain, at least in its upright position.
Das Gaszylinderbauteil ist nicht nur durch die zusätzliche drehfeste Halterung unter Vorspannung, insbesondere über Federstifte, am Lauf befestigt, sondern greift zudem noch formschlüssig in den Lauf ein, etwa durch einen komplementären, unrunden Querschnitt von Aufnahmebohrung und Lauf, oder durch einen axialen Zapfen am Ende des Gaszylinderbauteils, der in eine entsprechende Längsnut an der Außenseite des Laufes eingreift. Dieser Zapfen ist bevorzugt einstückig an das Gaszylinderbauteil angeformt. Dieser gegenseitige Formschluß von Lauf und Gaszylinderbauteil verhindert deren relative Verdrehung und ist imstande, Stoßkräfte, wie sie etwa beim Herunterfallen des Gewehres auftreten können, aufzunehmen. So wird gewährleistet, daß das Gaszylinderbauteil immer in seiner korrekten Lage beharrt. Dies gilt auch dann, wenn die Querbohrungen für die Federstifte ungenau sein sollten.The gas cylinder component is not only by the additional rotationally fixed support under bias, in particular spring pins, attached to the barrel, but also engages positively in the run, such as a complementary, non-circular cross-section of receiving bore and barrel, or by an axial pin at the end the gas cylinder component, which engages in a corresponding longitudinal groove on the outside of the barrel. This pin is preferably integrally formed on the gas cylinder component. This mutual positive engagement of barrel and gas cylinder component prevents their relative rotation and is able to absorb impact forces, such as may occur when the gun falls down. This ensures that the gas cylinder component always insists in its correct position. This is true even if the cross holes for the spring pins should be inaccurate.
Ferner sorgt die Klemmeinrichtung dafür, daß das Korn immer seinen festen Sitz aufweist, zumindest in der Gebrauchsstellung, ohne daß der Verschleiß etwas an diesem Sitz ändert, da die Klemmeinrichtung den Verschleiß ausgleicht.Furthermore, the clamping device ensures that the grain always has its tight fit, at least in the position of use, without the wear something on this Seat changes as the clamp compensates for wear.
So gelingt es, auf den Kornsockel ganz zu verzichten und statt dessen das Gaszylinderbauteil als vorderesThis makes it possible to dispense with the grain base completely and instead the gas cylinder component as a front
Kraftaufnahmelement auszubilden, das Kräfte aufnimmt und in den Lauf einleitet. So kann das Gaszylinderbauteil besonders bei Waffen mit Kunststoffgehäuse verwendet werden, da über den Lauf alle aufgebrachten Kräfte in die hierfür besonders ausgebildete Kraftaufnahme eingeleitet werden.Forming force receiving element that absorbs forces and introduces into the barrel. Thus, the gas cylinder component can be used especially in weapons with plastic housing, as all the forces applied are introduced into the specially trained force on the run.
Der Zweck der zusätzlich drehfesten Halterung unter Vorspannung ist es, das Gaszylinderbauteil so festzuspannen, daß es sich nicht lose schlagen kann. Bevorzugt ist es, federnde Stifte zu verwenden, die besonders bevorzugt als tangierende Spannstifte ausgebildet sind. Diese spannen das Gaszylinderbauteil nicht nur gegen die unrunde Stelle der Aufnahmebohrung, sondern auch gegeneinander so vor, daß ein äußerst fester Halt geschaffen ist, der auch imstande ist, erhebliche Kräfte aufzunehmen, die gegen die Federwirkung gerichtet sind, da die Federwirkung äußerst stark ist. Federstifte dieser Art sind zum Beispiel geschlitzte Hohlstifte aus Federblech, die mit Übermaß in die tangierenden Bohrungen gepreßt werden und dabei zusammengedrückt werden.The purpose of the additional rotationally fixed support under bias is to clamp the gas cylinder component so that it can not beat loose. It is preferred to use resilient pins, which are particularly preferably designed as tangential dowel pins. These clamp the gas cylinder component not only against the non-circular location of the receiving bore, but also against each other so that an extremely firm hold is created, which is also able to absorb considerable forces, which are directed against the spring action, since the spring action is extremely strong. Spring pins of this type are, for example, slotted hollow pins made of spring steel sheet, which are pressed with oversize into the tangential holes and thereby compressed.
Was das Korn angeht, so ist es bevorzugt, daß es einen Kornsockel aufweist, der um die Querachse schwenkbar ist und auf dem das Korn sitzt, und daß in der Unterseite des Kornsockels ein in dessen Längsrichtung beweglicher, nach unten abgefederter Keil angeordnet ist, der in eine Quernut mit keilförmigem Querschnitt eingreift. Die Quernut ist bevorzugt komplementär zum Keil ausgebildet, aber ist so tief, daß der Keil nie den Nutgrund erreichen kann. Tritt nun Verschleiß und/oder eine ungenaue Fertigung auf, dann wird der Keil von seiner Federung so tief in die Nut gedrückt, bis er in der Nut festsitzt. Da die Quernut im Gaszylinderbauteil, der Keil dagegen im Kornsockel sitzt, drückt die Federung außerdem den Kornsockel nach oben, so daß auch ein Radialspiel in seinem Querbolzen unterdrückt wird, um dessen Achse der Kornsockel geschwenkt wird, falls der Querbolzen ausgeleiert sein sollte.As regards the grain, it is preferred that it has a grain base which is pivotable about the transverse axis and on which the grain sits, and that in the underside of the grain base a movable in the longitudinal direction, down cushioned wedge is arranged engages in a transverse groove with a wedge-shaped cross-section. The transverse groove is preferably complementary to the wedge, but is so deep that the wedge can never reach the bottom of the groove. Now occurs wear and / or inaccurate manufacturing, then the wedge of his suspension pressed so deep into the groove until he is stuck in the groove. Since the transverse groove in the gas cylinder component, the wedge sits on the other hand, in the grain base, the suspension also pushes the grain base upwards, so that a radial play is suppressed in its cross bolt about the axis of the grain base is pivoted, if the cross bolt should be ausgeeiert.
Der Keil könnte durch einen Schraubenzieher o. dgl . aus der Quernut wieder herausgehoben werden. Bevorzugt ist allerdings, daß der Keil eine Handhabe trägt, mittels der er aus der Quernut heraushebbar ist. So ist das Korn jederzeit ohne besondere Mittel umlegbar oder aufklappbar, je nachdem, ob etwa das Korn einer anderen Zieleinrichtung im Wege ist oder nicht. Die genannte andere Zieleinrichtung kann die ideale optische Achse benutzen, da diese durch Umlegen des Korns freigegeben werden kann. Ist keine andere Zieleinrichtung vorhanden, kann aber das Korn die ideale optische Achse nutzen.The wedge could by a screwdriver o. The like. be lifted out of the cross groove again. However, it is preferred that the wedge carries a handle by means of which it can be lifted out of the transverse groove. Thus, the grain at any time without special means can be folded or hinged, depending on whether the grain of another target device is in the way or not. The said other aiming device can use the ideal optical axis, since this can be released by flipping the grain. If there is no other target device, the grain can use the ideal optical axis.
Ferner ist es möglich, bei Ausbildung einer Schiene an der Oberseite des Handschutzes, irgendwelche Zusatzgeräte auf diese Schiene aufzuschieben, ohne daß das Korn im Wege ist, da es ja rasch umgelegt werden kann.Furthermore, it is possible to postpone any additional devices on this rail when forming a rail on the top of the handguard, without the grain is in the way, since it can be folded down quickly.
Auch kann ein einstückiger, den Lauf zur Gänze umgebender Handschutz verwendet werden, der z. B. nach dem Lösen einer Halterung nach vorne abgezogen werden kann, wenn das Korn umgelegt ist.Also, a one-piece, the barrel entirely surrounding hand guard can be used, the z. B. can be deducted after releasing a holder forward when the grain is folded.
Es würde ausreichen, den Kornsockel einfach umzulegen, wenn er im Wege ist. Bevorzugt ist jedoch, daß das Gaszylinderbauteil an der Vorderseite eine weitere Quernut aufweist, in der der Keil einrückbar ist, wenn der Kornsockel umgelegt ist. So kann der Kornsockel im umgelegten Zustand ebenso fest und sauber verrastet werden, wie im aufgestelltenIt would be enough to just flip the grain base when it gets in the way. However, it is preferred that the gas cylinder component at the front has a further transverse groove in which the wedge is engageable when the grain base is folded. So the grain base in the folded state as firmly and cleanly locked as in the set up
Zustand. Der besondere Vorteil ist nicht nur, daß er nicht unversehens in der Visierlinie auftauchen kann, sondern, daß er vor Beschädigung und Abnutzung weitmöglichst geschützt ist, weil er nirgends anschlagen kann, solange er in irgendeiner Stellung festgelegt ist.Status. The particular advantage is not only that he can not appear unexpectedly in the sight line, but that he is as far as possible protected from damage and wear, because he can strike anywhere, as long as he is fixed in any position.
Bevorzugt weist das Gaszylinderbauteil eine Querbohrung auf, die zur Halterung von Zusatzeinrichtungen, des Handschutzes o. dgl. eingerichtet ist. So wird der besonders sichere und definierte Halt des Gaszylinderbauteils genutzt, um auch andere Bauteile in genau definierter Lage zu befestigen, etwa den Handschutz, der dann als Handschutz mit einer Picatinny- Schiene ausgebildet werden kann, auf der Zieleinrichtungen usw. angebracht werden können, denn mit der genauen und immer gleichen Lage der Bohrung ist auch die Lage des Handschutzes immer gleich. Es kann aber auch etwa ein Dreibein oder ein Granatwerfer an der Querbohrung angebracht werden.Preferably, the gas cylinder component has a transverse bore, which is set up to hold auxiliary devices, the hand guard or the like. Thus, the particularly secure and defined grip of the gas cylinder component is used to secure other components in a well-defined position, such as the hand guard, which can then be designed as a hand guard with a Picatinny- rail can be mounted on the target devices, etc., because with the exact and always same position of the hole, the position of the hand guard is always the same. But it can also be about a tripod or a grenade launcher attached to the transverse bore.
Es ist auch bevorzugt, daß das Gaszylinderbauteil mindestens auf der einen, bevorzugt auf beiden Seiten eine Halterung für einen Gewehrtrageriemen oder Schießriemen aufweist. So können Kräfte, die an der Vorderseite in das Gewehr eingeleitet werden, ohne ein besonderes, kraftaufnehmendes Teil eingeleitet werden. Dies ist besonders bei einem Gewehrgehäuse aus Kunststoff von Vorteil, das nur bedingt Kräfte aufnehmen kann.It is also preferred that the gas cylinder component has at least one, preferably on both sides, a holder for a rifle strap or a sling. Thus, forces that are introduced into the rifle at the front can be initiated without a special, force-absorbing part. This is particularly advantageous in a rifle housing made of plastic, which can absorb only limited forces.
Schließlich kann am Gaszylinderbauteil auch eine Bajonetthalterung bevorzugt einstückig ausgebildet werden.Finally, a bayonet mount can preferably be integrally formed on the gas cylinder component.
Diese Bajonetthalterung befindet sich in unmittelbarerThis bayonet mount is located in the immediate vicinity
Verbindung mit dem Lauf, im Gegensatz zu den letzten hundertConnection with the barrel, in contrast to the last hundred
Jahren der Waffenentwicklung, in denen man immer bemüht war, das Bajonett gerade nicht am Lauf tragend zu befestigen, sondern dort allenfalls seitlich abzustützen. So ist die Frage gelöst, wo man bei einem Gewehr mit Kunststoffgehäuse das Bajonett einfach, aber zuverlässig befestigt.Years of weapons development, in which one was always trying hard not to attach the bayonet to the barrel, but at best to support it laterally. That's how it is Solved a question, where you attach the bayonet simple, but reliable in a rifle with plastic housing.
Wie schon eingangs erwähnt, bezieht sich die Erfindung auch auf eine Handfeuerwaffe mit einem Gaszylinderbauteil, wie voranstehend beschrieben. Diese Handfeuerwaffe ist bevorzugt ein Schnellfeuergewehr in Normal- oder Kurzausführung.As already mentioned, the invention also relates to a handgun with a gas cylinder component, as described above. This handgun is preferably a rapid-fire rifle in normal or short version.
Der Gegenstand der Erfindung wird in der nachstehenden Beschreibung zweier Ausführungsbeispiele noch näher beschrieben. In der Zeichnung zeigt:The object of the invention will be described in more detail in the following description of two embodiments. In the drawing shows:
- Fig. 1 eine Teilansicht eines Schnellfeuer-Kurzgewehres im Längsschnitt,1 is a partial view of a rapid-fire short-rifle in longitudinal section,
- Fig. 2 die selbe Teilansicht im Schrägbild, und- Fig. 2 shows the same partial view in the oblique image, and
- Fig. 3 eine Teilansicht eines anderen Schnellfeuergewehres im Schrägbild.- Fig. 3 is a partial view of another rapid-fire rifle in the oblique view.
Die Fig. 1 und 2 zeigen ein Kurz-Schnellfeuergewehr, bei dem die Mündung 22 des Laufes 20 kurz vor dem vorderen Ende des1 and 2 show a short-speed rifle, in which the mouth 22 of the barrel 20 just before the front end of the
Handschutzes 70 (Fig. 2) und unmittelbar vor demHandguard 70 (Fig. 2) and immediately before the
Gaszylinderbauteil 10 liegt. Mündung 22 und Gaszylinderbauteil 10 ragen somit nur wenig aus dem Handschutz 70 nach vorne heraus.Gas cylinder component 10 is located. Mouth 22 and gas cylinder component 10 thus protrude only slightly out of the hand guard 70 to the front.
Das Gaszylinderbauteil 10 ist von vorne her über die Mündung 22 auf den Lauf 20 so aufgeschoben, daß es auf einem Abschnitt 24 sitzt, dessen Außendurchmesser zum Innendurchmesser einer Längsbohrung 12 im Gaszylinderbauteil 10 eine enge Übergangspassung oder sogar eine Preßpassung aufweist. Am hinteren Ende des Gaszylinderbauteils 10 ist ein Zapfen 50 einstückig angeformt, der in eine komplementäre Längsnut 52 eingreift, die an der Oberseite des Laufes 20 an dessen Paßabschnitt 24 anschließend ausgebildet ist.The gas cylinder component 10 is pushed from the front over the mouth 22 on the barrel 20 so that it sits on a portion 24 whose outer diameter to the inner diameter of a longitudinal bore 12 in the gas cylinder component 10 has a close transition fit or even a press fit. At the rear end of the gas cylinder component 10, a pin 50 is integrally formed, which engages in a complementary longitudinal groove 52 which is formed at the top of the barrel 20 at the fitting portion 24 thereafter.
Am hinteren Ende des Paßabschnitts 24 ist ein Absatz 26 ausgebildet, der ringförmig verläuft und nur durch die Längsnut 52 unterbrochen ist. Auf diesem Absatz 26 sitzt das montierte Gaszylinderbauteil 10 auf. Das Gaszylinderbauteil 10 ist somit relativ zum Lauf 20 um dessen Seelenachse 28 unverdrehbar durch den angeformten Zapfen 50 gehalten, der in die Längsnut 52 im Lauf 20 eingreift. Zusätzlich sind an der Unterseite des Laufes 20 zwei diesen schneidende Querbohrungen 14 im Gaszylinderbauteil 10 vorgesehen, in die je ein Federstift (nicht dargestellt) von außen her eingeschlagen ist.At the rear end of the fitting portion 24, a shoulder 26 is formed, which is annular and is interrupted only by the longitudinal groove 52. On this paragraph 26 sits the assembled gas cylinder component 10. The gas cylinder component 10 is thus held relative to the barrel 20 about the axis of its shaft 28 non-rotatably by the integrally formed pin 50, which engages in the longitudinal groove 52 in the barrel 20. In addition, two of these cutting transverse bores 14 are provided in the gas cylinder component 10 at the bottom of the barrel 20, in each of which a spring pin (not shown) is taken from the outside.
Durch das mehrfach über bestimmte Auflager (Federstifte/Querbohrungen 14; Zapfen 50/Längsnut 53; Passung von Aufnahmebohrung 12 und Paßabschnitt 24; Anlage von Gaszylinderbauteil 10 an den Absatz 26) ist das Gaszylinderbauteil 10 in seiner Lage selbst bei Verschleiß und beim Einwirken von ungewöhnlichen, äußeren Kräften völlig verdrehfest angebracht. Selbst nach mehrfachem Aus- und Einbau gelangen Lauf 20 und Gaszylinderbauteil 10 letztlich immer wieder zwangsläufig in ihre gleiche Relativlage.Due to the multiple over certain supports (spring pins / cross holes 14, pin 50 / longitudinal groove 53, fit of receiving bore 12 and fitting portion 24; investment of gas cylinder component 10 to the shoulder 26), the gas cylinder component 10 is in position even when worn and when exposed by unusual , external forces mounted completely rotationally. Even after repeated removal and installation, barrel 20 and gas cylinder component 10 ultimately inevitably reach their same relative position again and again.
Quer zur Seelenachse 28 ist eine durch einen Teil des Laufes 20 und einen Teil des Gaszylinderbauteils 10 hindurchgehende Gasentnahmebohrung 16 vorgesehen, die in eine Gaszylinderbohrung 18 einmündet, die parallel zur Seelenachse 28 verläuft und nach hinten offen ist.Arranged transversely to the axis of the shaft 28 is a gas removal bore 16 passing through a part of the barrel 20 and a part of the gas cylinder component 10, which opens into a gas cylinder bore 18 which runs parallel to the axis of the soul 28 and is open to the rear.
In der Gaszylinderbohrung 1 sitzt ein nach hinten verschieblicher Gaskolben 80, an dessen Rückseite ein Gasgestänge 82 angeschlossen ist. Nach vorne verläuft koaxial zur Gaszylinderbohrung 18 eine Entlastungsbohrung 84, in der ein Absperrschieber 88 sitzt, der auf der Vorderseite des Gaskolbens 80 einstückig mit diesem ausgebildet ist. Der Absperrschieber 88 durchsetzt den vom Gaskolben 80 freigehaltenen Raum der Gaszylinderbohrung 18. Der Gaskolben 80 trägt an seiner Rückseite einen Ringbund 78, der seinerseits gegen das Gaszylinderbauteil 10 anliegt, wenn die Einheit aus Gaszylinderbauteil 10 und Gaskolben 80 sich in Ruhe befindet. Der Gaskolben 80 kann demnach nur bis zu einem gewissen Ausmaß in die Gaszylinderbohrung 18 eingeführt werden.In the gas cylinder bore 1 sits a backwardly displaceable gas piston 80, at the rear of a Gas linkage 82 is connected. To the front runs coaxially to the gas cylinder bore 18, a relief bore 84, in which a gate valve 88 is seated, which is formed on the front side of the gas piston 80 integral therewith. The gate valve 88 passes through the space left free by the gas piston 80 of the gas cylinder bore 18. The gas piston 80 carries on its back an annular collar 78, which in turn abuts against the gas cylinder component 10 when the unit of gas cylinder component 10 and gas piston 80 is at rest. Accordingly, the gas piston 80 can be inserted into the gas cylinder bore 18 only to a certain extent.
Die Gasentnahmenbohrung 16 mündet in den genannten, freigehaltenen Raum der Gaszylinderbohrung 18 ein.The gas sampling bore 16 opens into said, free space of the gas cylinder bore 18 a.
Nach vorne ist die Entlastungsbohrung 84 durch eine Gasdüse 86 abgeschlossen, die an der Vorderseite des Gaszylinderbauteils 10 über dem Lauf 20 ins Freie mündet.To the front, the relief hole 84 is closed by a gas nozzle 86, which opens at the front of the gas cylinder component 10 via the barrel 20 into the open.
Wenn beim Schuß das Geschoß (nicht gezeigt) die Gsasentnahmebohrung 16 passiert hat, drängen hochgespannte Abschußgase durch diese in die Gaszylinderbohrung 18, wodurch der Gaskolben 80 nach hinten getrieben wird. Der einstückig mit dem Gaskolben 80 verbundene Absperrschieber 88 bewegt sich zwangsweise ebenfalls nach hinten, bis er aus der Entlastungsbohrung 84 nach hinten heraustaucht. Zu diesem Zeitpunkt ist der freigehaltene Raum der Gaszylinderbohrung 18 nahezu maximal ausgeweitet. Da sich nun die Entlastungsöffnung 84 öffnet, tritt das Gas nach vorne durch die Gasdüse 86 aus und verschmutzt deshalb nicht das Gasgestänge 82.When shot the projectile (not shown) has passed through the gas sampling bore 16, high-pressure discharge gases push through this into the gas cylinder bore 18, whereby the gas piston 80 is driven to the rear. The integral with the gas piston 80 gate valve 88 moves forcibly also backwards until he dives out of the relief hole 84 to the rear. At this time, the reserved space of the gas cylinder bore 18 is almost maximally expanded. Now that the discharge opening 84 opens, the gas exits forward through the gas nozzle 86 and therefore does not pollute the gas rod 82.
Das Gaszylinderbauteil 10 erstreckt sich, in Querrichtung gesehen, rund um den Lauf 20 und hat beiderseits des Laufes 20 seine größte Dicke. Der Abschnitt über dem Lauf 20 ist schmäler, und der Bereich von der Vorderseite bis fast zum Ende der Entlastungsbohrung 84 ist abgeflacht. Zwischen dem Übergang der Entnahmebohrung 84 in die Gasdüse 86 und dem Lauf 20 verläuft quer eine Scharnierbohrung 32. Rittlings über dem Vorderteil des abgeflachten Teils des Gasentnahmebauteils 10 sitzt ein Kornsockel 34 (siehe Fig. 2) , der mit zwei Schenkeln 36 den abgeflachten Teil des Gaszylinderbauteils 10 umgreift. Die Scharnierbohrung 32 im Gaszylinderbauteil 10 setzt sich durch die unteren Enden der Schenkel 36 fort, und es ist ein Scharnierstift (nicht gezeigt) in diese Bohrung 32 eingesetzt, der in den Schenkeln 36 oder im Gaszylinderbauteil festsitzt, aber im Gaszylinderbauteil 10 oder den Schenkeln 36 drehbar gelagert ist. Der vordere, obere Teil des Gaszylinderbauteils 10 ist so ausgebildet, daß der Kornsockel 34 mittels des Scharnierestifts zwischen einer vertikalen Lage (gezeigt) und einer horizontalen Lage hin- und hergeklappt werden kann.The gas cylinder member 10 extends, as seen in the transverse direction, around the barrel 20 and has on both sides of the barrel 20 his biggest thickness. The portion above the barrel 20 is narrower and the area from the front to almost the end of the relief bore 84 is flattened. A hinge bore 32 extends transversely between the transition of the removal bore 84 into the gas nozzle 86 and the barrel 20. A grain base 34 (see FIG Gas cylinder component 10 surrounds. The hinge bore 32 in the gas cylinder member 10 continues through the lower ends of the legs 36, and a hinge pin (not shown) is inserted into this bore 32, which is stuck in the legs 36 or gas cylinder component, but in the gas cylinder member 10 or legs 36 is rotatably mounted. The front upper portion of the gas cylinder member 10 is formed so that the grain base 34 can be folded back and forth between a vertical position (shown) and a horizontal position by means of the hinge pin.
In das Gaszylinderbauteil 10 sind zwei Quernuten 40 eingebracht, die der vertikalen und der horizontalen Lage des Kornsockels 34 entsprechen. Der Kornsockel 34 weist eine Sackbohrung 38 auf, die nach unten zwischen den beiden Schenkeln 36 offen ist. In der Bohrung sitzt ein Schieber 42, und zwischen diesem und dem Grund der Sackbohrung 38 sitzt eine Druckfeder (nicht gezeigt) , die den Schieber 42 nach unten drückt. An der Unterseite des Schiebers 42 ist eine Querleiste 44 einstückig ausgebildet oder fest eingesetzt. Diese Querleiste 44 und/oder die Quernuten 40 sind leicht konisch und verjüngen sich zur Sitze der Querleiste 44 und/oder zum Grund der Quernuten 40 hin, und zwar so, daß die Druckfeder die Querleiste 44 in die entsprechende Quernut 40 bis zur festen Anlage der Seitenwände von Quernut 40 und Querleiste 44 hin eindrückt. Nie aber kann der Scheitel der Querleiste 44 den Grund der jeweiligen Quernut 40 erreichen. In den Schenkeln 36 ist beiderseits ein Fenster 48 ausgebildet, in das jeweils eine Handhabe 46 eingreift, die am Schieber 42 befestigt ist. Der Schieber 42 ist seinerseits in der Sackbohrung 38 mit Gleitpassung, aber ohne wackeln zu können, geführt.In the gas cylinder component 10, two transverse grooves 40 are introduced, which correspond to the vertical and the horizontal position of the grain base 34. The grain base 34 has a blind bore 38 which is open down between the two legs 36. In the bore sits a slide 42, and between this and the bottom of the blind bore 38 is seated a compression spring (not shown) which pushes the slider 42 down. At the bottom of the slider 42, a cross bar 44 is integrally formed or fixed. This cross bar 44 and / or the transverse grooves 40 are slightly conical and taper towards the seats of the transverse bar 44 and / or the bottom of the transverse grooves 40 out, in such a way that the compression spring, the cross bar 44 in the corresponding transverse groove 40 to the fixed system of Side walls of Quernut 40 and transverse bar 44 pushes down. However, the crest of the transverse strip 44 can never reach the bottom of the respective transverse groove 40. In the legs 36, a window 48 is formed on both sides, in each of which a handle 46 engages, which is attached to the slider 42. The slider 42 is in turn in the blind bore 38 with sliding fit, but without being able to wiggle out.
Mittels der Handhaben 46 kann der Schieber 42 angehoben werden; dann löst die Querleiste 44 ihren Eingriff mit der jeweiligen Quernut 40 und der Kornsockel 34 kann mit dem Korn 30 in die andere (horizontale oder vertikale) Lage geklappt werden. Wird der Schieber irgendwann nach dem Verlassen der einen Quernut 30 losgelassen, dann scheuert er beim Umlegen des Kornsockels 34 über den vorderen, oberen Teil des Gaszylinderbauteils 10 und rastet in die andere Quernut 40 bei deren Erreichen ein. Das Gaszylinderbauteil 10 ist zu diesem Zweck glatt und kreisbogenförmig (mit der Achse der Scharnierbohrung 42 als Mittelachse) ausgeführt.By means of the handles 46, the slider 42 can be raised; then the cross bar 44 releases its engagement with the respective transverse groove 40 and the grain base 34 can be folded with the grain 30 in the other (horizontal or vertical) position. If the slide is released at some point after leaving the one transverse groove 30, then it scrubs when turning the grain base 34 over the front, upper part of the gas cylinder component 10 and snaps into the other transverse groove 40 when they reach. The gas cylinder component 10 is designed for this purpose smooth and circular arc-shaped (with the axis of the hinge bore 42 as the central axis).
So kann das Visier, das das Korn 30 und den Kornsockel 34 umfaßt, wahlweise mit einem Handgriff aus der vertikalenThus, the visor, which includes the grain 30 and the grain base 34, optionally with a handle from the vertical
Lage, die abgebildet ist, in die horizontale Lage verbracht werden, in der etwa das Aufschieben einer Zusatzeinrichtung auf eine Picatinny-Schiene 72 auf der Oberseite desPosition, which is shown, are spent in the horizontal position, in about the postponement of an accessory on a Picatinny rail 72 on top of the
Handschutzes 70 ermöglicht ist, oder in der der Handschutz 70 nach vorne vom Gewehr abgezogen werden kann.Hand guard 70 is possible, or in the hand guard 70 can be pulled forward from the rifle.
Das Gaszylinderbauteil 10 weist außerdem eine unter dem Lauf 20 liegende, quer verlaufende Paßbohrung 60 auf, an der weitere Zusatzeinrichtungen, wie ein Dreibein oder eine Lafette, ein Granatwerfer, ein Infrarotscheinwerfer o. dgl . angebracht werden kann. Der Handschutz 70 weist seinerseits eine großzügig bemessene Aussparung rund um den Außenumfang der verlängerten Paßbohrung 60 auf, damit die Anbringung der Zusatzeinrichtung nicht erschwert wird. In Fig. 3 ist ein anderes Gewehr gezeigt, das eine größereThe gas cylinder component 10 also has a lying below the barrel 20, transverse Paßbohrung 60, on the other options, such as a tripod or a carriage, a grenade launcher, an infrared headlight o. The like. can be attached. The hand guard 70 in turn has a generously sized recess around the outer periphery of the extended fitting bore 60, so that the attachment of the attachment is not difficult. In Fig. 3, another rifle is shown, which is a larger
Länge aufweist und bei dem der Lauf 20 über das Gaszylinderbauteil 10 noch um ein größeres Maß nach vorne übersteht. Der Handschutz ist nicht gezeigt, kann aber in Anlehnung an den Handschutz der Fig. 2 ausgebildet sein.Has length and in which the barrel 20 over the gas cylinder component 10 still protrudes to a greater extent to the front. The hand guard is not shown, but may be formed in accordance with the hand guard of FIG.
Am vorderen Ende des Laufes sitzt ein Mündungsfeuerdämpfer, der nicht nur das Mündungsfeuer verringert und verteilt, sondern auch die Mündung 22 (in Fig. 3 nicht sichtbar) schützt. An der Unterseite des Gaszylinderbauteils 10 ist unter dem Lauf 20 eine Halteschiene 98 ausgebildet.At the front end of the barrel sits a muzzle fire damper, which not only reduces and distributes the muzzle fire, but also protects the muzzle 22 (not visible in FIG. 3). On the underside of the gas cylinder component 10, a retaining rail 98 is formed below the barrel 20.
Der hintere Teil eines Bajonetts ist zu sehen, das einen Haltering 92 auf Höhe der Parierstange, einen Handgriff hinter der Parierstange und am Ende des Haltegriffs eine Haltenut 96 aufweist, die zur Haltenut 98 des Gaszylinderbauteils 10 komplementär ausgebildet ist.The rear part of a bayonet can be seen, which has a retaining ring 92 at the level of the quillons, a handle behind the quillons and at the end of the handle a retaining groove 96 which is complementary to the retaining groove 98 of the gas cylinder component 10.
Das Bajonett 90 ist von vorne her mit dem Haltering 92 über den Mündungsfeuerdämpfer 94 und mit der Haltenut 96 über dieThe bayonet 90 is from the front with the retaining ring 92 on the muzzle fire damper 94 and with the retaining groove 96 via the
Halteschiene 98 geschoben. Dort greift federnd ein SchieberRetaining rail 98 pushed. There resiliently engages a slider
(nicht gezeigt) am hinteren Ende des Bajonetts in eine (vom(not shown) at the rear end of the bayonet in a (from
Handgriff des Bajonetts verdeckte) Quernut ein.Bayonet handle covered) cross groove.
Das Gaszylinderbauteil weist ferner auf beiden Seiten eine Riemenbügelöse 62 auf. Der übrige Aufbau entspricht dem Beispiel der Fig. 1 und 2. Es ist zu sehen, daß alle Kräfte, die in das Vorderteil des Gewehres eingeleitet werden, vom Gaszylinderbauteil 10 aufgenommen und in den Lauf 20 eingeleitet werden. Der Haltering 92 kann zwar Querkräfte über den Mündungsfeuerdämpfer 94 in den Lauf 20 einbringen, aber dies geschieht nur im Ausnahmefall. The gas cylinder component further has on both sides a Riemenbügelöse 62. The rest of the structure is similar to the example of Figs. 1 and 2. It can be seen that all forces introduced into the front part of the rifle are taken up by the gas cylinder component 10 and introduced into the barrel 20. Although the retaining ring 92 can bring transverse forces on the muzzle fire damper 94 in the barrel 20, but this happens only in exceptional cases.
