Description

Die Erfindung betrifft einen Geradezugverschluß für eine Schußwaffe, insbesondere eine Repetierbüchse, mit einem Verschlußkopf, der in Laufrichtung in einer Kammerhülse verschiebbar und um seine Achse drehbar ist, mit einem im Verschlußkopf axial verschiebbaren Schlagbolzen und mit von einem Kammergriff gegen eine Schlagfeder axial beweglichen Mitteln sowie mit einem durch einen Abzughebel betätigbaren Fangstück.The invention relates to a straight-action breech for a firearm, in particular a bolt action rifle, with a locking head that can be moved in the direction of travel in a chamber sleeve and is rotatable about its axis, with an axially displaceable in the closure head Firing pin and with a chamber handle axially movable against a striking spring Means as well as with a catch piece actuated by a trigger lever.

Derartige Verschlüsse sind bereits aus älteren Gewehren, beispielsweise dem Schweizer Armeegewehr Modell 1889/1911/1931 und dem österreichischen Armeegewehr Modell 1889, bekannt. Diese Verschlüsse weisen jedoch aus heutiger Sicht gravierende Nachteile auf:Such closures are already from older rifles, for example the Swiss Army rifle model 1889/1911/1931 and the Austrian army rifle model 1889, known. From today's perspective, however, these closures have serious disadvantages on:

Die Waffe kann bei irrtürnlich ausgebautem Verschlußkopf abgefeuert werden, was schwerwiegende Folgen für den Schützen und umstehende Personen hat. Die überstrichene Fläche zwischen Einfahr- und Endposition bleibt bei allen Verschlüssen für die Verriegelung ungenutzt. Bei einem Verdrehwinkel von 90° zwischen Öffnen und Schließen ist dieser Verlust besonders groß. Festgeschossene Patronenhülsen müssen unter großem Kraftaufwand aus dem Lager ausgezogen werden, da eine günstige Übersetzung nicht gegeben ist. The weapon can be fired if the bolt head is erroneously removed, what has serious consequences for the shooter and bystanders. The swept over The area between the entry and end positions remains for all locks Lock not used. With a twist angle of 90 ° between opening and In conclusion, this loss is particularly large. Cartridge cases that have been jammed must be pulled out of the warehouse with great effort, as a cheap Translation is not given.

Weitere Verschlüsse mit ähnlichem Aufbau sind aus den Gewehren M16 und AUG bekannt. Diese Verschlüsse weisen separate Verschlußköpfe mit kleiner Drehbewegung auf, sind aber in der Regel gasdruckbetrieben und mit einem Hahnschluß kombiniert. Das Hahnschloß ist jedoch wegen des bei Repetierbüchsen erwünschten, weichen Schloßganges bei diesen nicht einsetzbar. Ein Schlagbolzenschloß bekannter Bauart läßt sich mit geringem Verdrehwinkel, der sich aus der vorgenannten Bauart ergibt, nicht mit hinreichendem Komfort spannen.Other breeches with a similar structure are from the M16 and AUG rifles known. These closures have separate closure heads with a small rotary movement on, but are usually gas-pressure operated and combined with a tap. However, the cock lock is soft because of the repeater rifle desired Castle aisle cannot be used with these. A firing pin lock of known design leaves not with a small twist angle, which results from the aforementioned design sufficient comfort.

Ein anderer aus der DE- 43 05 700 C1 bekannter Verschluß erlaubt keine markante Vergrößerung der Verriegelungsfläche, da die Federzungen der Verriegelungshülse nicht beliebig weit aufspreizbar sind. Diese Waffe benötigt eine separate Handspannung, wodurch der technische Aufwand relativ groß ist. Des weiteren fährt der Verschluß auf einer Leitschiene vor und zurück, weshalb Probleme bei der Zentrierung von Verschluß und Lauf entstehen können.Another closure known from DE 43 05 700 C1 does not allow a striking one Enlargement of the locking area, since the spring tongues of the locking sleeve are not are spread as far as possible. This weapon needs a separate hand tension, whereby the technical effort is relatively large. Furthermore, the shutter opens a guardrail back and forth, causing problems with the centering of the shutter and run can arise.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Geradzugverschluß, der eingangs genannten Gattung zur Verfügung zu stellen, der bei vereinfachter Bauweise und Handhabung eine sichere und schnelle Waffenfunktion gewährleistet.In contrast, the invention is based on the object Straight lock, to provide the type mentioned above, the with a simplified construction and handling a safe and fast weapon function guaranteed.

Gelöst wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale.This problem is solved by the in the characterizing part of claim 1 specified characteristics.

Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Merkmalen der Unteransprüche hervor.Advantageous embodiments of the invention result from the features of the subclaims forth.

Durch die erfindungsgemäße Anordnung ist vorteilhaft ein Zünden einer Patrone bei irrtümlich abgenommenem Verschlußkopf unmöglich, weil der Schlagbolzen nur im Verschlußkopf gelagert ist. Weiter vorteilhaft zeichnet sich dieser Verschluß dadurch aus, daß bei der Rückwärts- und Vorwärtsbewegung des Kammergriffs gleichzeitig der Verschlußkopf für die Ent- und Verriegelung in einem vergleichsweise geringen Winkelbereich, beispielsweise zwischen 15 und 30°, gedreht wird. Durch diese kurze Verriegelungsbewegung ist der Verlust an überstrichener Fläche zwischen Einfahr- und Endposition minimal. Die Verriegelungsfläche kann insbesondere vorteilhaft ca. 1/3 größer realisiert werden als bei den bekannten Verschlüssen. Ein weiterer Vorteil dieses Verschlusses besteht darin, daß die Schlagfeder beim Entriegelungsvorgang gleichzeitig gespannt und über ein Schlagstück an der Kammerhülse verriegelt wird. In dieser Sicherstellung kann weder ein unbeabsichtigtes Betätigen des Abzuges noch beim Fall oder Stoß auf die Waffe ein Schuß ausgelöst werden. Erst unmittelbar nach Einlegen der Patrone muß der Schütze den Kammergriff aus seiner hinteren Repetierstellung in die vordere Verriegelungsstellung des Verschlußkopfes schwenken, wobei die Sicherung erst in verriegelter Stellung des Verschlusses aufgehoben wird und eine Schußabgabe möglich ist.The arrangement according to the invention advantageously ignites a cartridge mistakenly removed locking head impossible because the firing pin only in Locking head is stored. This closure is also advantageous from that at the same time the backward and forward movement of the chamber handle Locking head for unlocking and locking in a comparatively small amount Angular range, for example between 15 and 30 °, is rotated. Through this short Locking movement is the loss of swept area between entry and End position minimal. The locking surface can particularly advantageously be about 1/3 can be realized larger than with the known closures. Another advantage of this Closure is that the striking spring during the unlocking process at the same time cocked and locked to the chamber sleeve by means of an impact piece. In this It cannot be ensured that the trigger is actuated unintentionally or in the event of a fall or a shot at the weapon. Only immediately after inserting the The shooter must move the bolt handle from his repeating position into the Swivel the front locking position of the breech head, the fuse first is lifted in the locked position of the breech and a shot is fired is possible.

Weiter vorteilhaft sind durch einen auf der Achse des Kammergriffs angeordneten Ausrückhebel durch ein günstiges Hebelverhältnis die aufzubringenden manuellen Kräfte beim Entriegeln und Verriegeln sehr gering, insbesondere, weil auch in Sicherstellung der Schlagbolzenfeder der weitere Verschlußmechanismus federentlastet ist. Durch einfache Betätigung des Kammergriffs wird nunmehr auch das Ausziehen festsitzender Patronenhülsen bei geringem Kraftaufwand ermöglicht.Also advantageous are those arranged on the axis of the chamber handle Release lever by a favorable lever ratio the manual forces to be applied when unlocking and locking very low, especially because it is also secured the firing pin spring the further locking mechanism is spring-loaded. By simple actuation of the chamber handle also makes pulling out more tight Cartridge casings made possible with little effort.

Dadurch werden die Kugeln 31 im nicht arretierten Zustand von dem hinteren Absatz 24 in ihrer Lage gehalten. Demgegenüber sind die Kugeln 31 im arretierten Zustand in einer radial umlaufenden innenseitigen Nute 27 der Kammerhülse 1 gefangen und werden innenseitig vom mittleren Absatz 22 des Spannstückes 18 abgestützt und gesichert. Das Schlagstück 5 weist an seinem rückwärtigen Ende einen nach innen gerichteten Vorsprung auf, der von einer Nase 6.1 eines von einem Abzugsstollen 15 (Figur 4) abstützbaren und um eine Achse 6.2 schwenkbaren Fangstück 6 gefangen ist. Die axiale Bewegung des Schlagstückes 5 wird durch eine Längsnut 34 und einen in der Kammerhülse 1 gelagerten Stift 33 begrenzt. The diameter of the balls 31 corresponds to half the difference in diameter between the outer diameter of the striking piece 5 and the rear shoulder of the clamping piece 18 and is greater than the wall thickness of the inside delimited by the bore 23 Percussion piece 5. Thus, the balls 31 in the unlocked state by the rear paragraph 24 held in place. In contrast, the balls 31 in locked state in a radially circumferential inner groove 27 of the chamber sleeve 1 and are caught on the inside by the middle shoulder 22 of the clamping piece 18th supported and secured. The striker 5 has one at its rear end inward projection on that of a nose 6.1 one of a trigger gallery 15 (FIG. 4) which can be supported and which can be pivoted about an axis 6.2 catch piece 6 is caught. The axial movement of the striking piece 5 is determined by a longitudinal groove 34 and a pin 33 supported in the chamber sleeve 1.

Am vorderen Ende des Schlagstückes 5 ist ein Ring 35 zur Sicherung des Spannstückes 18 gegen Herausfallen angeordnet.At the front end of the striking piece 5 is a ring 35 for securing the clamping piece 18 arranged against falling out.

Zur Erzeugung einer für die Ent- und Verriegelung notwendigen Drehbewegung enthält der Verschlußkopf 3 Steuerbolzen 9, die in Steuerkurven 2.2 der Steuerhülse 2 eingreifen und die jeweiligen Rotationsbewegungen des Verschlußkopfes 3 gegenüber dem Verriegelungsstück 14 während der Betätigung des Kammergriffs 13 durchführen. Diese Steuerbolzen 9 sind innerhalb des Verschlußkopfes 3 quer zur Axialrichtung angeordnet und greifen in schräg zur Achsrichtung 8 verlaufende Steuerkurven (Figuren 4, 5 und 6) der Steuerhülse 2 ein, wobei die Schrägstellung der Steuerkurve 2.2 gegenüber der Axialrichtung derartig bemessen ist, daß die Warzen 3.1 des Verschlußkopfes vollständig die korrespondierenden Verriegelungselemente des Verschlußstückes überdecken können. Je nach der Anzahl der Verriegelungselemente, die beispielsweise auf dem Umfang 6 bis 12, vorzugsweise 9 Warzen enthalten können, wird beispielsweise bei einer Achterteilung ein Verdrehwinkel von 20° erzielt.Contains to generate a rotary movement necessary for unlocking and locking the locking head 3 control bolts 9 which engage in control cams 2.2 of the control sleeve 2 and the respective rotational movements of the closure head 3 relative to the Carry out locking piece 14 while actuating the chamber handle 13. This Control bolts 9 are arranged transversely to the axial direction within the locking head 3 and engage in control cams extending obliquely to the axial direction 8 (FIGS. 4, 5 and 6) the control sleeve 2, the inclination of the control cam 2.2 compared to the The axial direction is such that the warts 3.1 of the closure head are complete cover the corresponding locking elements of the closure piece can. Depending on the number of locking elements, for example on the Scope 6 to 12, preferably 9 warts may include, for example Achieving a twist angle of 20 ° after an eight division.

Die Warzen 3.1 des Verschlußkopfes 3 sind ebenfalls schräg zur Achse 8 angestellt, wodurch beim Ent- und Verriegelungsvorgang des Verschlußkopfes 3 aus dem Verriegelungsstück 14 des Laufendes eine weitere Drehbewegung des Verschlußkopfes 2 verursacht wird. Dadurch ist es möglich, daß die Steuerbolzen 9 des Verschlußkopfes 3 an den vorderen Enden der jeweiligen Steuerkurven 2.2 der Steuerhülse 2 in radialer und in Umfangsrichtung verlaufende Sicherungsnuten 2.3 einrasten (Figur 6).The warts 3.1 of the closure head 3 are also inclined to the axis 8, whereby during the unlocking and locking process of the locking head 3 from the locking piece 14 of the running a further rotary movement of the closure head 2 is caused. This makes it possible for the control bolts 9 of the locking head 3 at the front ends of the respective control curves 2.2 of the control sleeve 2 in radial and engage circumferential securing grooves 2.3 (Figure 6).

Der Verschluß funktioniert wie folgt:The closure works as follows:

Der Ausrückhebel 10 wird über den Haltebolzen 11 verschwenkt, der die gemeinsame Achse für den Ausrückhebel 10 und den Kammergriff 13 bildet und bei der Betätigung sowohl eine Längs- als auch eine Drehbewegung macht. The release lever 10 is pivoted over the retaining pin 11, which is the common Axis for the release lever 10 and the chamber handle 13 forms and when actuated makes both a longitudinal and a rotational movement.

Wird nun, ausgehend von der verriegelten und abgeschlagenen Stellung der Verschluß betätigt, so hält man das Gewehr mit der linken Hand am Vorderschaft, umfaßt der rechten Hand die Kugel 12 und zieht daran in Richtung auf sich selbst. Hierdurch wird der Haltebolzen 11, der mit diesem verbundenen Ausrückhebel 10 und die mit ersteren verbundene Steuerhülse 2 in Bewegung gesetzt, bis die rückwärtige Kulisse 21 des Ausrückhebels 10 an das vordere Ende des Absatzes 20 des Spannstückes 18 anstößt, dieses gegen die Kugeln 31 drückt und über diese das Schlagstück 5 gegen den Druck der Schlagfeder 25 vom Zwischenstück 4 abhebt. Während dieser Rückwärtsbewegung wird über die in die Steuerhülse 2 eingebrachten Steuerkurven 2.2 und die Steuerbolzen 9 der Verschlußkopf 3 in Drehung versetzt und entriegelt. Am Ende der Längsbewegung springen die Kugeln 31 in die Nut 27 und legen das Schlagstück 5 fest, so daß der Kammergriff 13 und alle mit ihm verbundenen Bauteile entlastet werden.Now, starting from the locked and knocked-off position, the closure actuated, the rifle is held on the forearm with the left hand right hand the ball 12 and pulls it towards itself. This will the retaining pin 11, the release lever 10 connected to this and the former connected control sleeve 2 set in motion until the rear backdrop 21 of Release lever 10 abuts the front end of the shoulder 20 of the clamping piece 18, this presses against the balls 31 and via this the striking piece 5 against the pressure the striking spring 25 lifts off the intermediate piece 4. During this backward movement is about the introduced into the control sleeve 2 control cams 2.2 and the control pin 9 the locking head 3 is set in rotation and unlocked. At the end of the longitudinal movement the balls 31 jump into the groove 27 and set the striker 5 so that the Chamber handle 13 and all components connected to it are relieved.

Bis hierher wurde die Kammerhülse 1 in einer Rückwärtsbewegung gehindert, da sie über weitere Warzen 3.2 des Verschlußkopfes und eine korrespondierende Nut 1.2 der Kammerhülse 1 sowie über die Verriegelungselemente 3.1 mit dem Verriegelungsstück 14 verbunden war. Da jetzt die entriegelte Stellung erreicht ist, kann die Kammerhülse 1 mit allen darin befindlichen Bauteilen unter dem Zug der Hand den Rücklauf beginnen. Hierbei müssen die schräg zur Achse 8 angeordneten Verriegelungselemente 3.1 des Verschlußkopfes 1 durch korrespondierende Nuten (nicht dargestellt) des Laufendes gezogen werden, welches im Ausführungsbeispiel als separates Verriegelungsstück 14 auf einem nicht dargestellten Lauf aufgeschraubt ist. Der Verschlußkopf 3 wird in Drehung versetzt, bis die Steuerbolzen 9 eine Ruhestellung in den Sicherungsnuten 2.3 am Ende der Steuerkurve 2.2 erreicht haben. In dieser Position wird eine unbeabsichtigte Drehung des Verschlußkopfes in der Vorwärtsbewegung, beispielsweise beim Zuführen der Patronen, verhindert. So far, the chamber sleeve 1 has been prevented from moving backward because it about further warts 3.2 of the closure head and a corresponding groove 1.2 Chamber sleeve 1 and via the locking elements 3.1 with the locking piece 14 was connected. Now that the unlocked position has been reached, the chamber sleeve 1 start the rewind with all the components in it under the pull of your hand. Here, the locking elements 3.1 of the Locking head 1 by corresponding grooves (not shown) of the barrel are pulled, which in the exemplary embodiment is a separate locking piece 14 is screwed onto a barrel, not shown. The locking head 3 is in Rotation offset until the control pin 9 a rest position in the locking grooves 2.3 have reached 2.2 at the end of the control curve. In this position an unintended Rotation of the breech head in the forward movement, for example when Feeding the cartridges prevented.

Nach Erreichen der hinteren Endstellung wird der Verschluß wieder vorgeschoben. Dabei stützt sich die Steuerhülse 2, die sich unter dem Druck des Ausrückhebels 10 nach vorne bewegen will, mit dem quer zur Bewegungsrichtung angeordneten Flächen der Sicherungsnuten 2.3 am Ende der Steuerkurve 2.2 an den Steuerbolzen 9 ab, ohne diese aber verdrehen zu können. Der Druck wird auf den Verschlußkopf 3 übertragen und von diesem über die Warzen 3.2 und eine korrepondierende Nut 1.2 auf die Kammerhülse 1, so daß sich der gesamte Verschluß nach vorne bewegt. Dabei schiebt er die oberste, im Magazin befindliche Patrone vor sich her, bis die gedreht angeordneten Verriegelungselemente 3.1 in die korrespondierenden Nuten (nicht dargestellt) des Verriegegelungsstückes 14 eintreten, die Steuerbolzen 9 aus der Ruhestellung 2.3 am Ende der Steuerkurve 2.2 herausgedreht werden und sich die Steuerhülse 2 über den Verschlußkopf 3 schieben kann. Die Steuerbolzen 9 folgen den Steuerkurven 2.2 und verdrehen den Verschlußkopf 3 in die verriegelte Stellung. Währenddessen kommt die vordere Kulisse 36 des Ausrückhebels 10 in der Nut des Zwischenstückes 4 zur Anlage, schiebt das Zwischenstück 4 nach vorne und zieht über den Stift 29 das Spannstück 18 nach vorne, bis die Kugeln 31 aus der Nut 27 der Kammerhülse 1 austreten, das Schlagstück 5 unter dem Druck der Schlagfeder 25 um einen Weg vorschnellt, der sich aus den zulässigen Toleranzen aufsummiert, bis er von der Nase 6.1 des Fangstückes 6 gefangen wird, welches sich seinerseits auf den Abzugsstollen 15 abstützt.After reaching the rear end position, the lock is pushed forward again. The control sleeve 2 is supported, which is under the pressure of the release lever 10 wants to move forward with the surfaces arranged transversely to the direction of movement the securing grooves 2.3 at the end of the control curve 2.2 on the control pin 9, without but to be able to twist them. The pressure is transferred to the closure head 3 and from this over the warts 3.2 and a corresponding groove 1.2 on the Chamber sleeve 1, so that the entire closure moves forward. Doing so pushes he the top cartridge in the magazine in front of him until the cartridge is rotated Locking elements 3.1 in the corresponding grooves (not shown) of the Verriegegelungsstückes 14 occur, the control pin 9 from the rest position 2.3 on End of the control curve 2.2 are unscrewed and the control sleeve 2 over the Locking head 3 can slide. The control bolts 9 follow the control curves 2.2 and turn the locking head 3 into the locked position. In the meantime comes the front link 36 of the release lever 10 in the groove of the intermediate piece 4 for contact, pushes the intermediate piece 4 forward and pulls the clamping piece 18 over the pin 29 forward until the balls 31 emerge from the groove 27 of the chamber sleeve 1, the Percussion piece 5 jumps forward under the pressure of the striking spring 25 by a path that is summed up from the permissible tolerances until it comes from the nose 6.1 of the catch piece 6 is caught, which in turn is supported on the trigger gallery 15.

Durch ein günstiges Verhältnis der Hebellängen des Kammergriffs 13 zum Ausrückhebel 10 ≥ 2,5 : 1, vorzugsweise 3 : 1, lassen sich die vorbeschriebenen Vorgänge leicht manuell durchführen und ermöglichen des weiteren auch das Ausziehen festsitzender Patronenhülsen bei geringem Kraftaufwand. By a favorable ratio of the lever lengths of the chamber handle 13 to the release lever 10 ≥ 2.5: 1, preferably 3: 1, the processes described above can be easily carry out manually and also allow pulling out stuck Cartridge casings with little effort.
