Abstract

An elastic sleeve having a longitudinal slit is positioned between a bolt head and bolt carrier. The sleeve is inserted into an annular space in the bolt carrier when the sleeve is radially compressed allowing relative movement between the bolt head and bolt carrier. The sleeve is supported between the bolt head and an end surface of the bolt carrier when the sleeve is expanded preventing relative movement between the bolt head and the bolt carrier. The periphery of the uncompressed elastic sleeve contacts the bolt carrier or bolt head to thereby effectively damp the elastic sleeve.

Description

Verriegelter Verschluß für eine Selbstlade- Handfeuerwaffe, mit einem Verschlußkopf und Verschlußträger und einem federnden Sperring mit Locked breech for a self-loading handgun, with a breech head and breech holder and a resilient locking ring with
LängsschlitzLongitudinal slot
Die Erfindung betrifft einen verriegelten Verschluß aus Verschlußkopf und Verschlußtrager für eine Selbstlade- Handfeuerwaffe, mit einem federnden Sperring mit Langs- schlitz, der einen Abschnitt des Verschlußkopfes umgibt, bei unverriegeltem Verschluß aufgeweitet ist und sich zwischen dem Verschlußkopf und einer Stirnfläche des Ver- schlußtragers abstutzt, dagegen bei verriegeltem Verschluß in Umfangsrichtung zusammengedruckt ist und in einen Ringraum zwischen dem Verschlußkopf und dem Verschlußtrager reicht, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a locked breech from breech head and breech carrier for a self-loading handgun, with a resilient locking ring with an elongated slot, which surrounds a section of the breech head, is expanded when the breech is unlocked, and is supported between the breech head and an end face of the breech carrier , on the other hand, is compressed in the circumferential direction when the closure is locked and extends into an annular space between the closure head and the closure carrier, according to the preamble of claim 1.
Im deutschen Patent DE 197 13 988 Cl hat die Anmelderin einen Verschluß für eine Selbstlade-Handfeuerwaffe beschrieben. Dabei ist der Verschluß aus einem drehbaren Verschlußkopf und einem Verschlußtrager aufgebaut. Beim Entriegeln des Verschlusses wird der Verschlußkopf nach Zurücklegen seiner Drehbewegung während des nachfolgenden Rücklaufes nicht in Langsnuten des Waffengehäuses ge- fuhrt, sondern stattdessen mittels eines Sperringes auf einer festen Distanz zum Verschlußtrager gehalten.In German patent DE 197 13 988 Cl, the applicant has described a breech for a self-loading handgun. The closure is constructed from a rotatable closure head and a closure carrier. When the breech is unlocked, the breech head is not placed in the longitudinal slots of the weapon housing after it has returned its rotary movement during the subsequent return. leads, but instead held at a fixed distance from the lock carrier by means of a locking ring.
Der Inhalt dieses deutschen Patents wird durch die Bezug- nähme ausdrücklich in die vorliegenden Unterlagen als Offenbarung mit aufgenommen.The content of this German patent is expressly included in the present documents as a disclosure through the reference.
Ferner werden in den vorliegenden Unterlagen Lagebezeichnungen wie "vorne", "oben" o.dgl. verwendet. Diese Be- Zeichnungen beziehen sich auf eine Lage der Handfeuerwaffe, die sie bei horizontalem Schießen im üblichen Anschlag einnimmt, also mit horizontaler Seelenachse (Lauf- Mittelachse) und m aller Regel mit horizontal beweglichem Verschluß.In addition, in the present documents, location designations such as "front", "top" or the like. used. These designations refer to a position of the handgun, which it assumes in the usual shooting range when shooting horizontally, that is, with a horizontal core axis (barrel center axis) and generally with a horizontally movable breech.
Der Sperring ist eine durch einen Langsschlitz langsge- teilte Hülse aus Federblech. In belastetem Zustand, wenn der Sperring radial zusammengedruckt ist, ist der Langsschlitz in Umfangsrichtung zusammengedruckt und der Sper- ring hat einen kreisringfor igen Querschnitt. In unbelastetem Zustand weitet sich der Sperring federnd auf, der Langsschlitz ist geöffnet und der Sperring hat den Querschnitt etwa eines geöffneten Ovals.The locking ring is a sleeve made of spring sheet metal that is slowly divided by an elongated slot. In the loaded state, when the locking ring is radially compressed, the longitudinal slot is compressed in the circumferential direction and the locking ring has an annular cross section. In the unloaded state, the locking ring expands resiliently, the long slot is open and the locking ring has the cross section of an open oval.
Der Verschlußkopf weist an seinem vorderen Ende einenThe closure head has one at its front end
Kranz von Verriegelungswarzen auf, die in Umfangsrichtung verteilt sind, ahnlich dem US-Schnellfeuergewehr M16. In entriegeltem Zustand weist dieser Kranz von Verriegelungswarzen einen Abstand zum Verschlußtrager auf. Der Sperring ist dann unbelastet und umgibt den nach hinten weisenden Schaft des Verschlußkopfes. Dabei stutzt der Sperring sich gegen das hintere Ende des Kranzes und die vordere Stirnflache des Verschlußtragers ab und verhindert somit ein weiteres Eindringen des Schaftes in den Verschlußtrager. Zwischen dem Verschlußkopfschaft und dem Verschlußtrager wird ein den Schaft umgebender Ringraum gebildet, sobald der Schaft m den Verschlußtrager eingedrungen ist.Wreath of locking lugs, which are distributed in the circumferential direction, similar to the US rapid-fire rifle M16. In the unlocked state, this ring of locking lugs is at a distance from the lock carrier. The locking ring is then unloaded and surrounds the rearward pointing shaft of the locking head. The locking ring is braced against the rear end of the ring and the front end face of the fastener carrier and thus prevents further penetration of the shaft into the fastener carrier. An annular space surrounding the shaft is formed between the closure head shaft and the closure carrier as soon as the shaft has penetrated the closure carrier.
Wie schon beschrieben, sitzt im entriegelten Zustand das hintere Ende des Sperringes auf der vorderen Stirnflache des Verschlußtragers auf, m die auch der Ringraum einmundet, kann aber m diesen Ringraum nicht eindringen, weil der unbelastete Sperring einen unrunden Querschnitt aufweist, oder weil noch kein Ringraum gebildet ist.As already described, in the unlocked state, the rear end of the locking ring sits on the front end face of the lock carrier, which is also located in the annular space, but cannot penetrate this annular space because the unloaded locking ring has a non-circular cross-section, or because there is still no annular space is formed.
Der Querschnitt des unbelasteten Sperrings kann aber auch rund sein. Bei unbelastetem Sperring ist dann der Außendurchmesser des Sperrings großer als der Außendurchmesser des Ringraumes .The cross section of the unloaded locking ring can also be round. When the locking ring is not loaded, the outside diameter of the locking ring is then larger than the outside diameter of the annular space.
Beim Schließen des Verschlusses taucht dieser in bekannter Weise mit seinen Verriegelungswarzen zwischen Vor- sprungen hindurch, die ortsfest am Gehäuse der Waffe angebracht sind. Der Sperring schlagt dabei gegen abge- schrägte Hinterkanten der Vorsprunge an und wird dadurch radial zusammengedruckt. Nun liegt der Sperring mit kreisnngformigem Querschnitt rund um den Schaft des Verschlußkopfes dicht an und liegt mit seinem hinteren Ende genau der vorderen Einmündung des Ringraumes gegenüber. Es kann nun der Schaft mit dem ihn dicht umgebenden Sperring ohne weiteres in den Verschlußtrager eindringen, wobei der Ringraum ganz oder nur teilweise den Sperring aufnimmt. Der Verschluß wird dabei verriegelt.When the breech closes, it dips in a known manner with its locking lugs between projections which are fixed in place on the housing of the weapon. The locking ring strikes against the bevelled rear edges of the protrusions and is thereby radially compressed. Now the locking ring with a circular cross-section lies tightly around the shaft of the closure head and with its rear end lies exactly opposite the front mouth of the annular space. The shaft with the locking ring that surrounds it tightly can now easily penetrate into the closure carrier, the annular space receiving the locking ring in whole or in part. The lock is locked.
Beim Entriegeln bewegt sich der Verschlußtrager gegenüber dem Verschlußkopf nach hinten und gibt dabei den vorderen Abschnitt des VerschlußkopfSchaftes und damit den Sperring frei. Der Sperring federt daraufhin m seine unbelastete Position und stellt sicher, daß der Abstand zwi- sehen Verschlußkopf und Verschlußtrager beim weiteren Rück- und Vorlauf erhalten bleibt, bis der Verschluß wieder verriegelt wird.When unlocking, the breech carrier moves backwards relative to the breech head and thereby releases the front section of the breech head shaft and thus the locking ring. The locking ring then springs in its unloaded position and ensures that the distance between the breech head and the breech carrier is further Rewind and fast forward are retained until the lock is locked again.
In Versuchen hat sich dieser bekannte Verschluß hervorra- gend bewährt. Durch ihn ist es möglich geworden, den Aufbau des Verschlußgehäuses wesentlich zu vereinfachen, weil dieses den Verschlußkopf nicht mehr führen muß. In äußerst seltenen Fällen ist es jedoch bisweilen zu Störungen gekommen. Diese bestanden darin, daß der Sperring auch im unbelasteteten, aufgeweiteten Zustand in den Ringraum gelangt ist.This known closure has proven itself to be excellent in tests. It has made it possible to considerably simplify the construction of the closure housing because it no longer has to guide the closure head. In extremely rare cases, however, malfunctions have occasionally occurred. These consisted of the locking ring reaching the annular space even in the unloaded, expanded state.
Aufgabe der Erfindung ist es, diese Störungen auszuräumen.The object of the invention is to eliminate these faults.
Hier böte es sich an, den Außendurchmesser des unbelasteten Sperrings vor dem Einbau weiter aufzuweiten. Dann müßten allerdings größere Kräfte zum Zusammendrücken des Sperringes in Kauf genommen werden, die ihrerseits die Funktion der Waffe beeinträchtigen könnten. Zusätzlich oder stattdessen könnten auch die hintere Stirnfläche des Sperringes und die vordere Stirnfläche des Verschlußträgers plangeschliffen werden, um Abschrägungen zu vermeiden, die ein ungewolltes Einlaufen des Sperringes in den Ringraum erleichtern könnten. Es könnte auch die axiale Länge des Sperringes enger toleriert werden, um zu vermeiden, daß der Sperring kippt. Diese baulichen Maßnahmen sind allerdings kostenintensiv.It is advisable to widen the outer diameter of the unloaded locking ring before installation. Then, however, greater forces would have to be accepted to compress the locking ring, which in turn could impair the function of the weapon. In addition or instead of this, the rear end face of the locking ring and the front end face of the closure carrier could also be ground flat in order to avoid bevels which could facilitate an undesired entry of the locking ring into the annular space. The axial length of the locking ring could also be more closely tolerated to prevent the locking ring from tipping. However, these structural measures are cost-intensive.
Demgegenüber schlägt die Erfindung zur Lösung der obigen Aufgabe vor, dem Sperring Mittel zuzuordnen, die eine freie Schwingung desselben in radialer Richtung, also ein periodisches Öffnen und Schließen des" Längsschlitzes, behindert (Kennzeichen des Anspruchs 1) . Die Erfindung geht nämlich von der Annahme aus, daß die Ursache der obengenannten Störungen Schwingungen des Sperringes sind, die dieser bei offenem Langsschlitz m Umfangsrichtung ausfuhren kann und die ihn veranlassen, zu „atmen", also sich abwechselnd aufzuweiten und zu verengen. Wird der Sperring rhythmisch erregt, etwa durch Dauerfeuer, dann kann er sich zu Schwingungen aufschaukeln, die den Langsschlitz periodisch schließen und wieder offnen. Wenn bei geschlossenem Langsschlitz eine Langskraft auf den Verschluß einwirkt, kann tatsächlich der Sperring in den Ringraum eindringen.In contrast, the invention proposes to achieve the above object to assign the locking ring means which hinder free oscillation of the same in the radial direction, that is, periodic opening and closing of the "longitudinal slot" (characterizing part of claim 1). The invention is based on the assumption that the causes of the above-mentioned disturbances are vibrations of the locking ring, which the locking ring can execute in the open longitudinal slot in the circumferential direction and which cause it to "breathe", that is to say alternately widen and narrow rhythmically excited, for example by continuous fire, it can rock to vibrations, which periodically close and open the long slot.If a long force acts on the closure when the long slot is closed, the locking ring can actually penetrate into the annular space.
Die erfindungsgemaße Losung fuhrt zu einer Dampfung der Schwingung und mindert deren Amplitude. Sie verhindert, mit anderen Worten, daß der Langsschlitz sich unter den auftretenden Erregungen so weit schließt, daß der Sperring in den Ringraum einlaufen kann.The solution according to the invention leads to a dampening of the oscillation and reduces its amplitude. In other words, it prevents the longitudinal slot from closing so far under the excitation that occurs that the locking ring can enter the annular space.
Die erfindungsgemaßen Mittel zur Behinderung freier Schwingungen des Sperringes können eine erhöhte Federkonstante des Sperringes umfassen, etwa durch Verwendung eines dickeren Federstahlbleches als Baumaterial. Allerdings muß dann auch eine entsprechend größere Kraft aufgebracht werden, um den Verschluß zu verriegeln. Ferner wäre es möglich, etwa durch Stege, Nuten usw., mindestens im hinteren Bereich des Sperringes Schwingungsknoten zu erzeugen, welche die Schwingungs-Amplitude dort verringern. Auch durch einen ungeraden oder schräglaufenden Langsschlitz kann eine solche Wirkung erzielt werden. Al- lerdings ist in diesen Fallen für den Sperring ein entsprechender Bauaufwand vonnoten. Eine Beschichtung des Sperringes mit einem schwingungsdampfenden Material käme ebenfalls in Betracht, etwa m Form eines zum Ring gebogenen Bimetallstreifens . Gemäß einer bevorzugten Ausgestaltung der Erfindung (Ansprüche 2 und 3) bleibt jedoch der Sperring gegenüber dem bekannten Sperring weitgehend unverändert und wird nur leicht verlängert, denn die Ausbildung der Sperringes ist bereits hinsichtlich der Verschlußfunktion herstel- lungsopti iert . Der Ringraum wird an dem Ende, das in die Stirnflache des Verschlußtragers einmundet, um einen kurzen Bohrungsabschnitt verlängert, welcher das hintere Ende des Sperringes aufnimmt, wenn dieser sich entspannt, d.h. aufweitet. Der Durchmesser dieses Bohrungsabschnittes ist dabei soviel größer als der des restlichen Ringraumes, daß der Sperring mit aufgeweitetem Langsschlitz zwar aufgenommen werden, aber nicht oder nicht wesentlich über seine Sollage auseinanderschwingen kann. Eine schad- liehe Schwingung kann sich im Sperring also nicht aufschaukeln. Gleichzeitig zentriert der Bohrungsabschnitt auch den Sperring, so daß er nicht eine außermittige Lage einnehmen kann, die ein unerwünschtes Hineingleiten in den Ringraum beg nstigen könnte.The means according to the invention for preventing free vibrations of the locking ring can comprise an increased spring constant of the locking ring, for example by using a thicker spring steel sheet as the building material. However, a correspondingly greater force must then also be applied in order to lock the closure. Furthermore, it would be possible, for example by means of webs, grooves, etc., to generate oscillation nodes at least in the rear region of the locking ring, which reduce the oscillation amplitude there. Such an effect can also be achieved by an odd or inclined longitudinal slot. In these cases, however, a corresponding construction effort is necessary for the locking ring. A coating of the locking ring with a vibration-damping material would also be considered, for example in the form of a bimetal strip bent into a ring. According to a preferred embodiment of the invention (claims 2 and 3), however, the locking ring remains largely unchanged from the known locking ring and is only slightly extended, because the design of the locking rings is already production-optimized with regard to the locking function. The annular space is extended at the end which merges into the end face of the closure carrier by a short bore section which receives the rear end of the locking ring when it relaxes, ie widens. The diameter of this bore section is so much larger than that of the rest of the annular space that the locking ring can be received with a widened elongated slot, but cannot swing apart or cannot swing apart substantially over its desired position. A damaging vibration cannot build up in the locking ring. At the same time, the bore section also centers the locking ring, so that it cannot assume an eccentric position that could favor undesirable sliding into the annular space.
Es wäre auch möglich, eine Ringnut wie die Verlängerung des Bohrungsabschnittes nicht am rückwärtigen, sondern am vorderen Ende des vom Sperring umgebenen Abschnitt auszubilden, also etwa in den rückwärtigen Flachen von Verrie- gelungswarzen.It would also be possible to form an annular groove such as the extension of the bore section not at the rear but at the front end of the section surrounded by the locking ring, that is to say in the rear surfaces of locking lugs.
Dieser Anschlag "nach außen" muß allerdings nicht unbedingt am Verschlußtrager angeordnet sein, sondern kann sich auch am Verschlußkopf befinden.This "outward" stop does not necessarily have to be arranged on the closure carrier, but can also be located on the closure head.
Ausgedehnte Versuche haben ergeben, daß der erweiterte Bohrungsabschnitt zusammen mit dem verlängerten Sperring in jedem Fall eine völlig störungsfreie Funktion des Verschlusses gewährleistet. Bevorzugt sitzt der Sperring mit leichtem Andurck gegen die Wandung des Bohrungsabschittes in diesem (Anspruch 4) . Dadurch wird auch eine sich etwa einstellende Longi- tudinalschwingung in Achsrichtung des Sperringes gebremst und somit gedämpft.Extensive tests have shown that the enlarged bore section, together with the extended locking ring, guarantees a completely trouble-free function of the closure in any case. Preferably, the locking ring sits with a slight pressure against the wall of the bore section in this (claim 4). As a result, any longitudinal vibration that occurs in the axial direction of the locking ring is braked and thus damped.
Bevorzugt ist der hintere Teil des Verschlußkopfes unterteilt in einen vorderen Abschnitt, der den Inndendurch- messer des Ringraumes aufweist, um den der Sperring ange- ordnet ist, sowie einen hinteren Abschnitt, dessen Außendurchmesser dem des Ringraumes entspricht und der passend, aber verschieblich in einer Bohrung im Verschlußträger sitzt (Anspruch 5) . Diese Bohrung ist an ihrer Einmündung in die vordere Stirnfläche des Verschlußträ- gers vergrößert und bildet so den erfindungsgemäßen Boh- rungsabschnitt . Der Ringraum wird somit erst durch Eindringen des hinteren Teils des Verschlußkopfes in die Bohrung im Verschlußträger hergestellt. Bei entriegeltem Verschluß liegt nur eine schmale Ringnut zwischen der In- nenwand des Bohrungsabschittes und der Außenwand des vorderen Abschnitts des hinteren Teils des Verschlußkopfes vor. In dieser Ringnut sitzt das hintere Ende des Sperringes .The rear part of the closure head is preferably subdivided into a front section, which has the inner diameter of the annular space around which the locking ring is arranged, and a rear section, the outer diameter of which corresponds to that of the annular space and which fits but is displaceable in one Bore in the closure carrier sits (claim 5). This bore is enlarged at its confluence with the front end face of the closure carrier and thus forms the bore section according to the invention. The annular space is thus only produced by penetration of the rear part of the closure head into the bore in the closure carrier. When the closure is unlocked, there is only a narrow annular groove between the inner wall of the bore section and the outer wall of the front section of the rear part of the closure head. The rear end of the locking ring sits in this ring groove.

Die Beschreibung der gezeigten Elemente erfolgt hier nur abrißartig, da im eingangs genannten Patent DE 197 13 988 Cl bereits eine genaue Beschreibung erfolgt ist. Es ist ein Lauf 1 vorgesehen, an dessen hinterem Ende eine nach hinten überstehende Hülse 3 starr befestigt ist. Der Lauf 1 und die Hülse 3 können auch als ein mtegrier- tes Bauteil ausgebildet sein. Am hinteren Hulsenende ist ein Kranz radialer, nach innen gerichteter Vorsprunge 5 angeordnet, zwischen denen radial nach innen offene Axialnuten verlaufen. Das hintere Ende der Vorsprunge 5 weist eine Abschragung 9 auf. Zwischen dem hinteren Lau- fende und dem vorderen Ende des Kranzes aus Vorsprungen 5 ist eine nach innen offene Ringnut 7 gebildet.The description of the elements shown here is only in outline, since a precise description has already been given in the aforementioned patent DE 197 13 988 Cl. A barrel 1 is provided, at the rear end of which a rigidly projecting sleeve 3 is fixed. The barrel 1 and the sleeve 3 can also be designed as an integrated component. At the rear end of the sleeve there is a ring of radial, inwardly directed protrusions 5, between which radial grooves open radially inwards run. The rear end of the protrusions 5 has a bevel 9. An inwardly open annular groove 7 is formed between the rear barrel end and the front end of the ring of projections 5.
Ein Verschlußkopf 11 und ein Verschlußtrager 13 bilden einen Verschluß und sind zueinander sowie zum Lauf 1 und zur Hülse 3 koaxial ausgerichtet.A breech head 11 and a breech carrier 13 form a breech and are coaxially aligned with one another and with the barrel 1 and the sleeve 3.
Der Verschlußkopf 11 weist einen länglichen, insgesamt zylindrischen Schaft 17 auf, an dessen vorderem Ende ein Kranz von Verriegelungswarzen 15 ausgebildet ist. Der Schaft 17 weist einen vorderen Schaftabschnitt 19 und einen hinteren Schaftabschnitt 21 auf. Der vordere Schaftabschnitt 19 hat einen kleineren Durchmesser als der hintere Schaftabschnitt 21 und verlauft von den Verriegelungswarzen 15 aus nach hinten. Zwischen den beiden Schaftabschnitten 19 und 21 ist ein Absatz 20 ausgebildet.The closure head 11 has an elongated, generally cylindrical shaft 17, at the front end of which a ring of locking lugs 15 is formed. The shaft 17 has a front shaft section 19 and a rear shaft section 21. The front shaft section 19 has a smaller diameter than the rear shaft section 21 and extends from the locking lugs 15 to the rear. A shoulder 20 is formed between the two shaft sections 19 and 21.
Der Verschlußtrager 13 weist eine nach vorne offene Bohrung 23 auf, die den hinteren Schaftabschnitt 21 des Ver- schlußkopfes 11 passend, aber verschieblich aufnimmt. Die Bohrung 23 ist an ihrem vordere Ende im Durchmesser vergrößert und bildet dort einen vorderen Bohrungsabschnitt 25. Zwischen dem vorderen Bohrungsabschnitt 25 und dem restlichen Teil der Bohrung 23 ist ein Bohrungsabsatz 24 ausgebildet. Der vordere Schaftabschnitt 19 des Verscnlußkopfes 11 wird von einem Sperring 27 umgeben. Dieser ist aus Federstahlblech gebildet, hat eine Wandstarke, die etwa der halben Differenz zwischen den Außenαurchmessern des er- sten 19 und zweiten 21 Schaftabschnittes entspricht, weist einen durchgehenden Langsschlitz auf und hat m zusammengedrucktem Zustand (bei geschlossenem Langsschlitz) einen kreisringformigen Querschnitt. Unter Einwirkung der Federkraft der Federstahlblechs federt der Sperring 27 auseinander (Fig. 2), so daß sich der Langsschlitz öffnet.The closure support 13 has a bore 23 which is open to the front and which accommodates the rear shaft section 21 of the closure head 11 in a suitable but slidable manner. The bore 23 is enlarged in diameter at its front end and forms a front bore section 25 there. A bore shoulder 24 is formed between the front bore section 25 and the remaining part of the bore 23. The front shaft section 19 of the locking head 11 is surrounded by a locking ring 27. This is made of spring steel sheet, has a wall thickness which corresponds approximately to half the difference between the outer diameters of the first 19 and second 21 shaft sections, has a continuous elongated slot and, in the compressed state (with the elongated slot closed), has an annular cross section. Under the action of the spring force of the spring steel sheet, the locking ring 27 springs apart (FIG. 2), so that the elongated slot opens.
In entriegeltem Zustand (Fig. 2) ist der Verschlußkopf 11 mindestens so weit aus dem Verschlußtrager 13 herausgezo- gen, daß der Bohrungsabsatz 24 zwischen dem erweiterten vorderen Bohrungsabschnitt 25 und der restlichen Bohrung 23 genau auf gleicher Hohe liegt wie der Schaftabsatz 20, oder besser noch aus Toleranzgrunden ein wenig weiter.In the unlocked state (FIG. 2), the closure head 11 has been pulled out of the closure carrier 13 at least to such an extent that the bore shoulder 24 between the enlarged front bore section 25 and the remaining bore 23 lies exactly at the same height as the shaft shoulder 20, or better a little further for tolerance reasons.
Der Sperring 27 befindet sich m aufgeweitetemThe locking ring 27 is widened
(weitgehend lastfreiem) Zustand und sitzt mit seinem vorderen Ende auf den hinteren Flachen der Verriegelungswarzen 15 sowie mit seinem hinteren Ende auf dem Bohrungsabsatz 24 auf. Er verbindet somit den Verschlußkopf 11 mit dem Verschlußtrager 13 und verhindert ein Einschieben des Verschlußkopfes 11 in die Bohrung 23 des Verschlußtragers 13.(largely load-free) state and sits with its front end on the rear surfaces of the locking lugs 15 and with its rear end on the bore shoulder 24. It thus connects the closure head 11 to the closure carrier 13 and prevents insertion of the closure head 11 into the bore 23 of the closure carrier 13.
Beim Schließen des Verschlusses laufen die Verπegelungs- warzen 15 zwischen den Vorsprungen 5 hindurch, bis derWhen the closure is closed, the locking projections 15 run through between the projections 5 until the
Sperring 27 mit seiner vorderen Kante gegen die Abschra- gung 9 der Vorsprunge 5 auflauft. Im Verlaufe der weiteren Bewegung wird der Sperring 27 so weit zusammengedruckt, bis er mit seinem vorderen Teil radial innerhalb der Vorsprunge 5 liegt, die ihn gegen die Wirkung seiner Federkraft eng an den Außenumfang des vorderen Schaftab- Schnitts 19 andrucken, wobei sein Langsschlitz weitgenend geschlossen ist und er einen kreisringformigen Querschnitt eingenommen hat. Mit seinem hinteren Ende sitzt nun der Sperring 27 ausschließlich auf dem zwischen dem ersten 19 unα dem zweiten 21 Abschnitt gebildeten Schaftabsatz 20 auf, so daß der Schaft 17 nunmehr eine durchgehende zylindrische Außenflache aufweist, die von den Außenumfangsflachen des Sperrings 27 und des hinteren Schaftabschnitts 21 gebildet sind.The locking ring 27 runs with its front edge against the bevel 9 of the protrusions 5. In the course of the further movement, the locking ring 27 is pressed together until its front part lies radially inside the protrusions 5, which, against the action of its spring force, press it closely against the outer circumference of the front shaft. Press section 19, its longitudinal slot is largely closed and it has an annular cross-section. With its rear end, the locking ring 27 now rests exclusively on the shaft shoulder 20 formed between the first 19 and the second 21 section, so that the shaft 17 now has a continuous cylindrical outer surface which extends from the outer peripheral surfaces of the locking ring 27 and the rear shaft section 21 are formed.
Nun kann der Schaft 17 m die Bohrung 23 eindringen und der Verschlußtrager 13 verschiebt sich relativ zum Verschlußkopf 11 nach vorne, wobei der Verschlußkopf durch nicht dargestellte Mittel gedreht wird (Fig. 1) . Die Ver- πegelungswarzen 15 hintergreifen nun von vorne her die Vorsprunge 5. Der Verschluß ist verriegelt.Now the shaft 17 can penetrate the bore 23 and the breech carrier 13 moves forward relative to the breech head 11, the breech head being rotated by means not shown (FIG. 1). The locking lugs 15 now engage behind the projections 5 from the front. The closure is locked.
Beim Offnen des Verschlusses wird der Verschlußtrager 13 nach hinten bewegt. Der Verschlußkopf 11 wird dabei in seine Ausgangslage zurückgedreht und dann nach hinten gezogen. Dabei ist der Schaft 17 aus der Bohrung 23 so weit herausgetaucht, wie m Fig. 2 gezeigt. Nun verlaßt der Sperring 27 den Eingriffsbereich der Vorsprunge 5 und ihrer Abschragung 9, federt radial nach außen und greift in den Bohrungsabsatz 24 ein. Dabei liegt das hintere Ende des Sperringes 27 mit seinem Außenumfang leicht gegen den Innenumfang des Bohrungsabschitts 25 an. Nun kann sich der Verschlußkopf 11 nicht mehr relativ zum Verschlußtrager 13 bewegen. When the closure is opened, the closure carrier 13 is moved backwards. The closure head 11 is rotated back into its initial position and then pulled back. The shaft 17 is immersed out of the bore 23 as far as shown in FIG. 2. Now the locking ring 27 leaves the engagement area of the projections 5 and their bevel 9, springs radially outwards and engages in the bore shoulder 24. The outer end of the rear end of the locking ring 27 lies slightly against the inner circumference of the bore section 25. Now the closure head 11 can no longer move relative to the closure carrier 13.
