Definitions
- the invention relates to a rifle lock or the like.
- the barrel is inserted from one side and the locking piece can be inserted from the other side, the locking piece carrying locking lugs at its front end and the housing having grooves corresponding to the locking lugs, which open into a rotation limited by the end, which allows the locking piece to be rotated, and wherein the locking piece is provided with a resiliently pivotable cartridge extractor which lies between two locking lugs and ends in a claw.
- Such a rifle lock is e.g. known from GB-A-2 060 144. If the rifle barrel is blocked by some foreign body and a shot is fired, the pressure of the powder gases, which rises far above the permissible value, can cause the cartridge case, which is usually made of brass, to tear. Although the cartridge case is firmly encased in the cartridge chamber of the barrel, its rear end, which has a groove for engaging the extractor claw, projects beyond the barrel end into the recess of the housing.
- the rear end of the cartridge protrudes into the breech block as far as the butt plate, but this frame has an interruption due to the breech block in the area of the extractor claw, the resiliently pivotable extractor claw not being able to withstand the increased gas pressure because it has play in the recess.
- the diameter of the recess is in fact chosen so that the extractor can carry out the swiveling movement required to reach over the cartridge bottom until the claw engages in the cartridge groove, regardless of the respective rotational position of the closure piece. If the cartridge case tears in the area of the extractor claw, neighboring gun parts are also destroyed or blown off by the powder gases escaping, so that the shooter is at maximum risk of injury. In addition, such damage to the weapon can result that it can no longer be used.
- the invention is therefore based on the object of eliminating these deficiencies and of creating a rifle lock of the type described at the outset, in which the risk of injury to the shooter or destruction of the weapon is eliminated by simple means in the event of barrel barrage.
- the invention achieves the stated object in that the inner wall of the housing forms a surface for the radial support of the extractor claw when the closure piece is locked in the region of the recess, and a recess that allows the extractor to pivot is arranged in the circumferential direction next to this support surface.
- the extractor claw Since the extractor claw is supported radially when the closure piece is locked, it can no longer yield and forms the previously missing part of the rear end of the cartridge closing frame through the closure piece. Tearing of the cartridge case in the previously endangered area is thus prevented with certainty. Nevertheless, the extractor can fully fulfill its function, since when it is rotated out of the locking position in the recess provided next to the support surface, it has enough play to perform the required pivoting movement. This does not result in an increase in the manufacturing effort required, since it is only a question of shaping the recess accordingly.
- the barrel 2 is screwed into a housing 1 connected to the rifle stock (not shown) from one side (from the left according to FIG. 1) and the locking piece 3 is inserted from the other side.
- the closure piece 3 has locking lugs 4 at its front end, and the housing is provided with longitudinal grooves 5 corresponding to these lugs 4 (FIG. 2).
- the warts 4 pass through the grooves 5, which open into a recess 6, so that the closure piece can be rotated for locking purposes when the warts 4 pass through the grooves 5 and have reached the recess 6.
- the locked position of the closure piece 3 is shown.
- the closure piece 3 is provided with a resiliently pivotable cartridge extractor 7, which lies between two locking lugs 4 and ends in an extractor claw 7.
- the cartridge case 9 lying in the cartridge chamber of the barrel 2 protrudes somewhat towards the rear over the barrel end and has an annular groove 10 into which the extractor claw 8 can engage.
- the inner wall of the housing 1 forms in the region of the recess 6 a surface 11 for the radial support of the extractor claw 8 when the closure piece 3 is locked. From FIG. 2 it can be seen that a recess 12 which allows the extractor to pivot is arranged next to the support surface 11. For manufacturing reasons, the recess 12 corresponds to the longitudinal grooves 5 for the locking lugs 4.
Description
Die Erfindung betrifft einen Gewehrverschluss mit einem Gehäuse od.dgl., in dem von der einen Seite der Lauf eingesetzt und von der anderen Seite das Verschlussstück einschiebbar ist, wobei das Verschlussstück an seinem Vorderende Verriegelungswarzen trägt und das Gehäuse den Verriegelungswarzen entsprechende Nuten aufweist, die in eine vom Laufende begrenzte, das Verdrehen des Verschlussstückes ermöglichende Ausdrehung münden, und wobei das Verschlussstück mit einem zwischen zwei Verriegelungswarzen liegenden, in einer Kralle endenden, federnd schwenkbaren Patronenauszieher versehen ist.The invention relates to a rifle lock or the like. In which the barrel is inserted from one side and the locking piece can be inserted from the other side, the locking piece carrying locking lugs at its front end and the housing having grooves corresponding to the locking lugs, which open into a rotation limited by the end, which allows the locking piece to be rotated, and wherein the locking piece is provided with a resiliently pivotable cartridge extractor which lies between two locking lugs and ends in a claw.
Ein solcher Gewehrverschluss ist z.B. aus der GB-A-2 060 144 bekannt. Ist dabei der Gewehrlauf durch irgendeinen Fremdkörper verdämmt und wird dann ein Schuss abgegeben, so kann es durch den weit über den zulässigen Wert ansteigenden Druck der Pulvergase zu einem Reissen der in der Regel aus Messing bestehenden Patronenhülse kommen. Zwar ist die Patronenhülse im Patronenlager des Laufes fest umfasst, doch steht sie mit ihrem Hinterende, das zum Eingreifen der Auszieherkralle eine Rille aufweist, über das Laufende in die Ausdrehung des Gehäuses vor. Innerhalb der Ausdrehung ragt das Patronenhinterende bis zum Stossboden in das Verschlussstück ein, doch weist diese Umrahmung durch das Verschlussstück im Bereich der Auszieherkralle eine Unterbrechung auf, wobei die federnd schwenkbare Auszieherkralle dem erhöhten Gasdruck keinesfalls standhalten kann, weil sie in der Ausdrehung Bewegungsspiel hat. Der Durchmesser der Ausdrehung ist nämlich so gewählt, dass der Auszieher die zum Übergreifen des Patronenbodens bis zum Einrasten der Kralle in die Patronenrille erforderliche Schwenkbewegung unabhängig von der jeweiligen Drehstellung des Verschlussstückes durchführen kann. Kommt es zu einem Reissen der Patronenhülse im Bereich der Auszieherkralle, so werden durch die austretenden Pulvergase auch benachbarte Waffenteile zerstört bzw. abgesprengt, so dass höchste Verletzungsgefahr für den Schützen besteht. Darüber hinaus können sich solche Beschädigungen der Waffe ergeben, dass sie nicht mehr weiter verwendbar ist.Such a rifle lock is e.g. known from GB-A-2 060 144. If the rifle barrel is blocked by some foreign body and a shot is fired, the pressure of the powder gases, which rises far above the permissible value, can cause the cartridge case, which is usually made of brass, to tear. Although the cartridge case is firmly encased in the cartridge chamber of the barrel, its rear end, which has a groove for engaging the extractor claw, projects beyond the barrel end into the recess of the housing. Within the recess, the rear end of the cartridge protrudes into the breech block as far as the butt plate, but this frame has an interruption due to the breech block in the area of the extractor claw, the resiliently pivotable extractor claw not being able to withstand the increased gas pressure because it has play in the recess. The diameter of the recess is in fact chosen so that the extractor can carry out the swiveling movement required to reach over the cartridge bottom until the claw engages in the cartridge groove, regardless of the respective rotational position of the closure piece. If the cartridge case tears in the area of the extractor claw, neighboring gun parts are also destroyed or blown off by the powder gases escaping, so that the shooter is at maximum risk of injury. In addition, such damage to the weapon can result that it can no longer be used.
Bei einem anderen bekannten Gewehrverschluss dieser Art (GB-A-2 024 383) wird mit Hilfe von Anlaufflächen am Patronenauszieher einerseits und am Verschlussgehäuse andererseits die Auszieherkralle beim Ausziehvorgang daran gehindert, dass sie den hinteren Patronenrand überspringt. Dadurch wird aber die Sicherheit des Schützen bei einem etwaigen Schuss mit verdämmtem Lauf deshalb nicht verbessert, weil die durch die Anlaufflächen erzielte Abstützung für den Patronenauszieher nicht in unmittelbarer Nähe des Patronenbodens erfolgt. Die Auszieherkralle kann daher schon bei geringem radialem Druck nach aussen nachgeben und demnach ein Aufreissen des Patronenbodens nicht verhindern. Die Abstützung des Patronenausziehers erfolgt erst dann, wenn der Verschluss entriegelt wird, so dass im massgeblichen Zeitpunkt bei der Schussabgabe keine Abstützung vorhanden ist.In another known rifle closure of this type (GB-A-2 024 383), with the help of contact surfaces on the cartridge extractor on the one hand and on the breech housing on the other hand, the extractor claw is prevented from jumping over the rear cartridge rim during the extraction process. However, this does not improve the safety of the shooter in the event of a shot with a barred barrel because the support for the cartridge extractor achieved by the contact surfaces is not in the immediate vicinity of the cartridge base. The extractor claw can therefore yield to the outside even at low radial pressure and therefore cannot prevent the cartridge base from tearing open. The cartridge extractor is only supported when the bolt is unlocked, so that there is no support at the relevant time when the shot is fired.
Es ist zwar auch schon bekannt, dem Patronenauszieher in der Verriegelungsstellung des Verschlusses eine feste Stütze zu geben (US-A-3 253 362), wobei es sich aber um eine andere Konstruktion mit dem Vorderende des Verschlussstückes rückversetzten Verriegelungswarzen handelt und die Funktionssicherheit nicht gewährleistet ist. Es ist nämlich für das Eingreifen der Auszieherkralle in die Rille der Patrone Voraussetzung, dass die Patrone an der der Auszieherkralle diametral gegenüberliegenden Seite bereits formschlüssig in die entsprechende Hinterschneidung des Verschlussstückes eingerastet ist, was nur beim händischen Einführen der Patrone möglich ist, weil ein an der Stirnseite des Verschlussstückes angeordneter, gefederter Ausstosser die aus einem Magazin aufsteigende Patrone darin hindern würde, in die richtige Lage in der Hinterschneidung einzutreten. Hat aber die Patrone von vornherein nicht die richtige Lage an der Stirnfläche des Verschlussstückes, so kann die Auszieherkralle in die Rille der Patrone überhaupt nicht eingreifen.It is also known to give the cartridge extractor a firm support in the locking position of the breech (US Pat. No. 3,253,362), but this is a different construction with locking lugs set back with the front end of the breech piece and does not guarantee functional reliability is. It is namely a prerequisite for the engagement of the extractor claw in the groove of the cartridge that the cartridge on the diametrically opposite side of the extractor claw is already positively engaged in the corresponding undercut of the closure piece, which is only possible when the cartridge is inserted by hand because one on the Spring-loaded ejector arranged on the front side of the closure piece would prevent the cartridge rising from a magazine from entering the correct position in the undercut. However, if the cartridge is not in the correct position on the end face of the closure piece from the start, the extractor claw cannot engage in the groove of the cartridge at all.
Schliesslich ist es bekannt, zur Verhinderung von Ausziehstörungen im Gehäuse eine zusätzliche Einrichtung vorzusehen, die die Auszieherkralle beim Öffnen des Verschlusses fest im Eingriff mit dem Patronenrand hält (DE-C-277 213). Diese Einrichtung ergibt zwar eine Abstützung für den Patronenauszieher in der Verriegelungsstellung, ist aber für Drehverschlüsse unbrauchbar, weil sich der Patronenauszieher beim drehenden Verriegeln aus dem Wirkungsbereich dieser Einrichtung wegbewegen würde. Ausserdem ist die bekannte Einrichtung nur dann wirksam, wenn eine Druckfeder einen Riegel nach jedem Ladevorgang wieder zuverlässig in die Funktionsstellung zurückbringt. Bei stärkerer Verschmutzung oder Vereisung im Bereich der Riegellagerung ist die Rückbewegung durch die Druckfeder aber keineswegs gesichert. Ausserdem handelt es sich um eine zusätzliche Konstruktion aus kleinen, störanfälligen Teilen.Finally, it is known to provide an additional device in the housing to prevent pull-out disturbances, which holds the pull-out claw firmly in engagement with the cartridge rim when the breech is opened (DE-C-277 213). Although this device provides support for the cartridge extractor in the locking position, it is unusable for rotary locks because the cartridge extractor would move away from the area of action of this device when rotating locking. In addition, the known device is only effective if a compression spring reliably brings a bolt back into the functional position after each loading process. In the event of heavy soiling or icing in the area of the transom bearing, the return movement is by no means secured by the compression spring. In addition, it is an additional construction made of small, susceptible parts.
Demnach liegt der Erfindung die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Gewehrverschluss der eingangs geschilderten Art zu schaffen, bei dem die Gefahr der Verletzung des Schützen bzw. der Zerstörung der Waffe bei einer Laufverdämmung mit einfachen Mitteln beseitigt ist.The invention is therefore based on the object of eliminating these deficiencies and of creating a rifle lock of the type described at the outset, in which the risk of injury to the shooter or destruction of the weapon is eliminated by simple means in the event of barrel barrage.
Die Erfindung löst die gestellte Aufgabe dadurch, dass die Gehäuseinnenwand im Bereich der Ausdrehung eine Fläche zur radialen Abstützung der Auszieherkralle bei verriegeltem Verschlussstück bildet und in Umfangsrichtung neben dieser Stützfläche eine das Verschwenken des Ausziehers ermöglichende Ausnehmung angeordnet ist.The invention achieves the stated object in that the inner wall of the housing forms a surface for the radial support of the extractor claw when the closure piece is locked in the region of the recess, and a recess that allows the extractor to pivot is arranged in the circumferential direction next to this support surface.
Da also die Auszieherkralle bei verriegeltem Verschlussstück radial abgestützt ist, kann sie nicht mehr nachgeben und bildet den bisher fehlenden Teil der das Patronenhinterende einschliessende Umrahmung durch das Verschlussstück. Es wird also ein Reissen der Patronenhülse in dem bisher gefährdeten Bereich mit Sicherheit verhindert. Dennoch kann der Auszieher seine Funktion voll erfüllen, da er bei aus der Verriegelungsstellung verdrehter Lage in der neben der Stützfläche vorgesehenen Ausnehmung genügend Bewegungsspiel hat, um die erforderliche Schwenkbewegung auszuführen. Dabei ergibt sich keine Erhöhung des notwendigen Herstellungsaufwandes, da es ja nur darum geht, die Ausdrehung entsprechend zu formen.Since the extractor claw is supported radially when the closure piece is locked, it can no longer yield and forms the previously missing part of the rear end of the cartridge closing frame through the closure piece. Tearing of the cartridge case in the previously endangered area is thus prevented with certainty. Nevertheless, the extractor can fully fulfill its function, since when it is rotated out of the locking position in the recess provided next to the support surface, it has enough play to perform the required pivoting movement. This does not result in an increase in the manufacturing effort required, since it is only a question of shaping the recess accordingly.
