The enlarged region needed to rotate the locking components (4) takes the form of an annular space (5) wherein a locking sleeve (10) is fitted to rotate between an open and a locked end position. The locking sleeve (10) has a widened section (11) per locking component (4) which is aligned with the widened part (9) of the breech block drilling (2) in the open end position. The annular space (5) is completely filled by the locking sleeve (10) and the pushed-in breech block (8).

Description

Verschlußeinrichtung, insbesondere für Handfeuerwaffen Locking device, in particular for small arms
Die Erfindung betrifft eine Verschlußeinrichtung, ins¬ besondere für Handfeuerwaffen, mit einem eine Patrone in ein Patronenlager einschiebenden Verschlußkolben, der zumindest zwei radial abstehende Riegelelemente aufweist, und mit einem Verschlußgehäuse, das pro Rie¬ gelelement eine längsverlaufende Ausweitung der Ver¬ schlußkolbenbohrung aufweist, die in eine Erweiterung mündet, in die das Riegelelement verdrehbar ist und die eine hintergreifbare Stützfläche aufweist. Derartige Verschlußeinrichtungen, sogenannte Bajonettverschlüsse sind bei einer Vielzahl von Handfeuerwaffen üblich.The invention relates to a locking device, in particular for small arms, with a locking piston which pushes a cartridge into a cartridge chamber and which has at least two radially projecting locking elements, and with a locking housing which has a longitudinal extension of the locking piston bore per locking element, which opens into an extension into which the locking element can be rotated and which has a support surface that can be gripped behind. Such locking devices, so-called bayonet locks are common in a variety of handguns.
Werden hülsenlose Patronen verschossen, stellt die verschlußseitige Abdichtung des Patronenlagers ein bis¬ her nicht zufriedenstellend gelöstes Problem dar, da die Ausbildung des Bajonettverschlusses einerseits im Verschlußgehäuse längsverlaufende Ausweitungen für die Riegel und andererseits auch den Freiraum zum Verdrehen der Riegel erfordert. Beide sind nach dem Verdrehen in die verriegelte Stellung nicht ausgefüllt, sondern nur durch den vorderen Bereich des Verschlußkolbens abge¬ deckt.If caseless cartridges are fired, the closure-side sealing of the cartridge chamber represents a problem which has not been satisfactorily solved to date, since the formation of the bayonet closure on the one hand in the breech housing requires longitudinal extensions for the bolts and, on the other hand, also the space for turning the bolts. After turning into the locked position, both are not filled, but are only covered by the front area of the locking piston.
Die Erfindung hat es sich daher zur Aufgabe gestellt, eine Verschlußeinrichtung der eingangs genannten Art so auszubilden, daß der Verriegelungsfreiraum ausgefüllt und die Verschlußkolbenbohrung besser abgedichtet ist.The object of the invention is therefore to design a closure device of the type mentioned at the outset in such a way that the locking clearance is filled and the closure piston bore is better sealed.
Erfindungsgemäß wird dies dadurch erreicht, daß die Er¬ weiterung als Ringraum ausgebildet ist, in dem eine Verschlußhülse zwischen einer offenen und einer verrie¬ gelten Endposition des Verschlußkolbens verdrehbar an- geordnet ist, und daß die Verschlußhülse pro Riegelele¬ ment eine Ausweitung aufweist, die in der offenen End-This is achieved according to the invention in that the extension is designed as an annular space in which a closure sleeve is rotatably arranged between an open and a locked end position of the closure piston, and in that the closure sleeve per locking element has an extension which in the open end
ERSATZBLATT position mit der Ausweitung der Verschlußkolbenbohrung fluchtet.REPLACEMENT LEAF position is aligned with the expansion of the locking piston bore.
Somit füllt die Verschlußhülse den Ringraum vollständig aus und der Hohlraum der Verschlußhülse selbst wird durch den eingeschobenen Verschlußkolbenkopf ausge¬ füllt. Dabei überdeckt die hintere Stirnfläche der Ver¬ schlußhülse auch die längsverlaufenden Ausweitungen der Verschlußkolbenbohrung.Thus, the closure sleeve completely fills the annular space and the cavity of the closure sleeve itself is filled by the inserted piston head. The rear end face of the closure sleeve also covers the longitudinal extensions of the closure piston bore.
Damit die Verschlußhülse beim Verschieben des Ver¬ schlußkolbens in der zum Einführen der Riegel benötig¬ ten offenen Endposition liegt, sieht eine bevorzugte Ausführung der Erfindung vor, daß im Verschlußgehäuse ein zur Drehachse der Verschlußhülse feder¬ beaufschlagtes Rastelement und am Umfang der Verschlu߬ hülse eine die offene Endposition definierende Rastaus¬ nehmung vorgesehen sind. Somit kann sich die Verschlu߬ hülse nicht zufällig verdrehen. Eine Verrastung der verriegelten Stellung kann dann ebenso einfach erzielt werden, wenn am Umfang der Verschlußhulse eine zweite, die verriegelte Endposition definierende Rastausnehmung vorgesehen ist.In order for the closure sleeve to be in the open end position required for inserting the bolt when the closure piston is moved, a preferred embodiment of the invention provides that in the closure housing there is a latching element which is spring-loaded to the axis of rotation of the closure sleeve and one on the circumference of the closure sleeve locking recess defining the open end position are provided. Thus, the closure sleeve cannot twist accidentally. A locking of the locked position can be achieved just as easily if a second locking recess defining the locked end position is provided on the circumference of the closure sleeve.
Da somit nur Rotationsflächen im Verriegelungsbereich ausgebildet sind, läßt sich eine verbesserte Abdichtung dadurch erzielen, daß der Ringraum und die Verschlu߬ hülse patronenlagerseitig konische Dichtflächen aufwei¬ sen, wobei bevorzugt zusätzlich noch zwischen den Dichtflächen ein Dichtelement vorgesehen werden kann, das die Form einer konischen Hülse aufweist.Since only rotational surfaces are thus formed in the locking area, an improved sealing can be achieved in that the annular space and the closure sleeve have conical sealing surfaces on the cartridge bearing side, wherein preferably a sealing element can also be provided between the sealing surfaces, which has the shape of a conical one Has sleeve.
Bevorzugt kann weiters vorgesehen sein, daß das Ver¬ schlußgehäuse zumindest eine umfangseitig in den Ring- räum mündende Gasaustrittsöffnung aufweist. Diese wird dann wirksam, wenn aufgrund eines Materialfehlers, einer Funktionsstörung oder anderer einen Gasaustritt in den Ringraum bewirkender Mängel das Rückschlagen der Gase in die Verschlußkolbenbohrung erfolgen könnte.It can preferably also be provided that the closure housing has at least one gas outlet opening that opens into the annular space on the circumference. This will effective if, due to a material defect, a malfunction or other deficiencies causing a gas to escape into the annular space, the gases could be kicked back into the bores of the sealing piston.
Nachstehend wird nun die Erfindung an Hand der Figuren der beiliegenden Zeichnung näher erläutert ohne darauf beschränkt zu sein.The invention will now be explained in more detail with reference to the figures of the accompanying drawing, without being limited thereto.
Fig. 1 zeigt einen Längsschnitt durch das Verschlußge¬ häuse im Verriegelungsbereich des Verschlußkolbens, Fig. 2 eine Explosionsdarstellung des Riegelbereiches des Verschlußkolbens, Fig. 3 einen Schnitt nach der Li¬ nie III-III der Fig. 1 mit verriegeltem Verschlußkolben und Fig. 4 eine schematische Stirnansicht der unverrie- gelten Verschlußhülse aus der durch die Linie IV-IV ge¬ sehenen Position.1 shows a longitudinal section through the lock housing in the locking area of the lock piston, FIG. 2 shows an exploded view of the locking area of the lock piston, FIG. 3 shows a section along line III-III of FIG. 1 with the lock piston locked, and FIG. 4 is a schematic front view of the unlocked closure sleeve from the position seen by the line IV-IV.
Eine einen Bajonettverschluß bildende Verschlußeinrich- tung weist ein an den Lauf 20 anschließendes Verschlu߬ gehäuse 1 und einen verschiebbaren Verschlußkolben 8 auf, der mit zwei, drei, gegebenenfalls auch mehreren umfangseitigen Riegelelementen 4 versehen ist. Pro Rie¬ gelelement 4 ist die Verschlußkolbenbohrung 2 mit einer längsverlaufenden Ausweitung 9 versehen, die in einen durch einen Ringraum 5 gebildete Erweiterung mündet. Der in die Schließstellung vorgeschobene Verschlußkol¬ ben 8 kann um die Achse 3 verdreht werden, wobei die Riegelelemente 4 an der Stirnfläche 6 des Ringraumes 5 abgestützt werden, sodaß das an der Patrone anliegende vordere Ende 22 des Verschlußkolbens 8 im am Ende des Laufes 20 ausgebildeten Patronenlager 19 eingedrückt verriegelt ist. Der Ringraum 5 verjüngt sich zum Patro¬ nenlager 19 hin und weist eine konische Dichtfläche 7 auf. Im Ringraum 5 ist eine Verschlußhülse 10 drehbar ange¬ ordnet, deren mit der Verschlußkolbenbohrung 2 fluch¬ tende Bohrung 18 ebenfalls pro Riegelelement 4 eine Ausweitung 11 aufweist, sodaß der in die Schließstel¬ lung vorgeschobene Verschlußkolben 8 die Verschlußhülse 10 vollständig ausfüllt. Die Verschlußhülse 10 ist in zwei Endstellungen durch ein Rastelement 12 verrastet, das mittels einer Feder 21 in umfängliche Rastausneh- mungen 13, 14 der Verschlußhülse 10 gedrückt wird.A locking device forming a bayonet lock has a locking housing 1 adjoining the barrel 20 and a displaceable locking piston 8 which is provided with two, three, and possibly also a plurality of locking elements 4 on the circumference. For each locking element 4, the locking piston bore 2 is provided with a longitudinal extension 9, which opens into an extension formed by an annular space 5. The locking piston 8 pushed into the closed position can be rotated about the axis 3, the locking elements 4 being supported on the end face 6 of the annular space 5, so that the front end 22 of the locking piston 8 resting on the cartridge is formed in the end of the barrel 20 Cartridge chamber 19 is pressed in locked. The annular space 5 tapers towards the cartridge chamber 19 and has a conical sealing surface 7. In the annular space 5, a closure sleeve 10 is rotatably arranged, the bore 18 aligned with the closure piston bore 2 also has an enlargement 11 per locking element 4, so that the closure piston 8 pushed into the closed position completely fills the closure sleeve 10. The closure sleeve 10 is locked in two end positions by a locking element 12 which is pressed into circumferential locking recesses 13, 14 of the closure sleeve 10 by means of a spring 21.
Fig. 1 und 4 zeigen die unverriegelte Endstellung der Verschlußhülse 10, in der die Riegelaufnahmeausweitun¬ gen 9 und 11 der Verschlußkolbenbohrung 2 und der Ver¬ schlußhülse 10 miteinander fluchten, und das Rastele- ment 12 in die Rastausnehmung 13 eingedrückt ist.1 and 4 show the unlocked end position of the locking sleeve 10, in which the locking receptacle extensions 9 and 11 of the locking piston bore 2 and the locking sleeve 10 are flush with one another, and the locking element 12 is pressed into the locking recess 13.
Wird nun der Verschlußkolben 8 verriegelt, so wird die Verschlußhulse 10 mitverdreht, wobei das Rastelement 12 in die zweite Rastausnehmung 14 (Fig. 3) einrastet. Da- bei stützen sich die Riegelelemente 4 an der Stützflä¬ che 6 (Fig. 1) des Ringraumes 5 ab und der konische Teil 15 des Mantels der Verschlußhülse 10 wird gegen die Dichtfläche 7 angepreßt. Wie aus den Fig. 3 und 4 ersichtlich, füllt der Verschlußkolben 8 die Verschluß- hülse 10 aus, die ihrerseits wieder den Ringraum 5 vollständig ausfüllt und die Ausweitungen 9 der Ver¬ schlußkolbenbohrung 2 überdeckt (Fig. 3). Da der koni¬ sche Teil 15 gegen die konische Fläche 15 gepreßt wird, ist das Patronenlager 19 gegen die Verschlußkolbenboh- rung 2 abgedichtet.If the locking piston 8 is now locked, the locking sleeve 10 is also rotated, the locking element 12 snapping into the second locking recess 14 (FIG. 3). The locking elements 4 are supported on the support surface 6 (FIG. 1) of the annular space 5 and the conical part 15 of the casing of the closure sleeve 10 is pressed against the sealing surface 7. As can be seen from FIGS. 3 and 4, the sealing piston 8 fills the sealing sleeve 10, which in turn completely fills the annular space 5 and covers the extensions 9 of the sealing piston bore 2 (FIG. 3). Since the conical part 15 is pressed against the conical surface 15, the cartridge chamber 19 is sealed against the sealing piston bore 2.
In Fig. 2 ist eine konische Dichthülse 16 gezeigt, die an den konischen Teil 15 der Verschlußhülse 10 an¬ schließt, sodaß die Abdichtung des Teiles 15 zur Fläche 7 nochmals verbessert wird. Der Ringraum 5 ist weiters mit seitlichen Gasaustrittsöffnungen 17 (Fig. l) verse¬ hen, sodaß bei einer Fehlfunktion die Gase nicht über die Verschlußkolbenbohrung 2 entweichen, sondern durch die Öffnungen 17 austreten können. 2 shows a conical sealing sleeve 16 which adjoins the conical part 15 of the closure sleeve 10, so that the sealing of the part 15 to the surface 7 is further improved. The annular space 5 is also provided with lateral gas outlet openings 17 (FIG. 1) so that, in the event of a malfunction, the gases do not escape through the sealing piston bore 2, but can exit through the openings 17.
