Description

Die Erfindung betrifft eine Verriegelung einer Verschlusshülse eines Verschlusses einer Feuerwaffe, wobei eine Kammer vorhanden ist, die ein Schlagstück und eine Schlagfeder wenigstens teilweise umschließt, wobei die Schlagfeder herausragt.The invention relates to a locking of a locking sleeve of a breech block of a firearm, a chamber being present which at least partially encloses a striking piece and a striking spring, the striking spring protruding.

Verschlusshülsen bei Waffen-Verschlüssen sind weit verbreitet. Dabei stellt sich die Verbindung von Verschlusshülse mit der durch diese umgebener Kammer als unflexibel und oftmals umständlich zu Montieren dar. So ist bekannt eine Verschlusshülse mit einem an der Innenseite befindlichen Gewinde zu verschrauben. Dies ist unhandlich in der Montage. Ebenfalls sind seitlich wirkende Schrauben oder auch Verstiftungen bekannt. Diese sind nicht, oder nur sehr schwer, wieder lösbar. Eine einfache Wartung ohne eine Werkbank mit Spezialwerkzeug ist so nicht möglich Die DE102012217686 offenbart ein Geradezug-Repetiergewehr mit einem Verschlussmechanismus.Socket sleeves for weapon breeches are widespread. The connection of the closure sleeve with the chamber surrounded by it turns out to be inflexible and often cumbersome to assemble. For example, it is known to screw a closure sleeve with a thread located on the inside. This is unwieldy to assemble. Laterally acting screws or pegs are also known. These cannot be resolved, or only with great difficulty. Simple maintenance without a workbench with special tools is not possible DE102012217686 discloses a straight-pull repeating rifle with a breech mechanism.

Aus der DE OS 653 253 ist eine Selbstladewaffe mit gleitendem Lauf, Drehverschluss und Einrichtung zum Zusammenhalten der zusammengeschobenen Schlossteile und zum Festhalten des Schlosshülsendeckels bekannt, bei welcher ein Organ der Einrichtung durch axiale Verschiebung den Hülsendeckel zum Abnehmen freigibt, wobei auf diesem Organ ein selbsttätig wirkendes Sperrglied angeordnet ist, welches nach erfolgter axialer Verschiebung des Organs die Einrichtung mit der zurückgezogenen Kammer kuppelt.From the DE OS 653 253 a self-loading rifle with sliding barrel, twist lock and device for holding together the pushed together lock parts and for holding the lock case cover is known, in which an organ of the device releases the case cover for removal by axial displacement, with an automatically acting locking member being arranged on this organ, which according to Once the organ has been axially displaced, the device couples with the retracted chamber.

Aufgabe der Erfindung ist es eine verbesserte Verriegelung einer Verschlusshülse zur Verfügung zu stellen, bei der die Handhabung beim Montieren und Demontieren einfacher ist.The object of the invention is to provide an improved locking of a closure sleeve, in which the handling during assembly and disassembly is easier.

Diese Aufgabe wird durch eine Verriegelung einer Verschlusshülse nach den Merkmalen des Anspruchs 1.This object is achieved by locking a closure sleeve according to the features of claim 1.

Erfindungsgemäß ist eine Verriegelung einer Verschlusshülse eines Verschlusses einer Feuerwaffe vorgeschlagen, wobei eine Kammer vorhanden ist, die ein Schlagstück und eine Schlagfeder wenigstens teilweise umschließt, wobei die Schlagfeder herausragt, wobei die Verschlusshülse die Kammer wenigstens teilweise umschließt und das herausragende Ende der Schlagfeder sich an der Verschlusshülse abstützt, und dass die Verschlusshülse an der Kammer vermittels einer hierzu an der Verschlusshülse von einer Freigabelage zu einer Sperrlage drehbar gelagerten Sperrvorrichtung lösbar festgelegt werden kann, wobei ein Vorsprung an der Kammer an einem Sperrvorsprung an der Sperrvorrichtung formschlüssig hintergreift, wenn dieser in die Sperrlage gedreht ist.According to the invention, a locking of a locking sleeve of a breech block of a firearm is proposed, wherein a chamber is present which at least partially encloses a striker and a striker spring, the striker spring protruding, the locking sleeve at least partially enclosing the chamber and the protruding end of the striker spring is attached to the Locking sleeve is supported, and that the locking sleeve can be releasably fixed to the chamber by means of a locking device rotatably mounted on the locking sleeve from a release position to a locking position, a projection on the chamber engaging behind a locking projection on the locking device in a form-fitting manner when this is in the locking position is rotated.

Hierdurch ist auf besonders effektive Weise eine sichere Montage in einer Endlage ermöglicht, ohne, dass Stifte oder Schrauben präzise von geschultem Personal eingebracht werden müssen.This enables safe assembly in an end position in a particularly effective manner, without the need for pins or screws to be inserted precisely by trained personnel.

Eine vorteilhafte und daher bevorzugte Weiterbildung der Erfindung sieht vor, dass die Kammer vermittels der Schlagfeder, die sich zum einen an der Verschlusshülse und zum anderen in der Kammer abstützt, gegen den Sperrvorsprung der Sperrvorrichtung vorgespannt ist. Auf der anderen Seite stützt sich die Schlagfeder an einem Schlagstück oder über einen Signalstift an dem Schlagstück ab.An advantageous and therefore preferred further development of the invention provides that the chamber is pretensioned against the locking projection of the locking device by means of the striker spring, which is supported on the one hand on the locking sleeve and on the other hand in the chamber. On the other hand, the striker spring is supported on a striker or via a signal pin on the striker.

Bevorzugterweise ist wenigstens eine Vorrast an dem Sperrvorsprung vorhanden ist, sodass beim Drehen der Sperrvorrichtung in die Sperrlage durch den Vorsprung an der Kammer zunächst die Vorrast am Sperrvorsprung überwunden werden muss. Durch die Vorrast ergibt sich eine definierte Endlage zwischen Sperrvorrichtung, Verschlusshülse und Kammer.There is preferably at least one preliminary detent on the locking projection, so that when the locking device is rotated into the locking position by the projection on the chamber, the preliminary detent on the locking projection must first be overcome. The pre-locking results in a defined end position between the locking device, locking sleeve and chamber.

Von Vorteil ist die Sperrvorrichtung senkrecht zur Wirkrichtung der Schlagfeder drehbar an der Verschlusshülse in einer Sperrvorrichtungs-Ausnehmung gelagert ist. Dies ist insbesondere deswegen von Vorteil, da die Betätigung der Sperrvorrichtung senkrecht zur Wirkungsrichtung der Schlagfeder erfolgt, wodurch die Festlegung einfacher Handhabbar ist.Advantageously, the locking device is rotatably mounted on the locking sleeve in a locking device recess perpendicular to the direction of action of the mainspring. This is particularly advantageous because the locking device is actuated perpendicular to the direction of action of the mainspring, so that the fixing is easier to handle.

Vorteilhafterweise ist zwischen der Sperrvorrichtung und der Sperrvorrichtungs-Ausnehmung ein in einer Nut an der Sperrvorrichtung gelagerter Halte-Ring vorhanden, der einen Reibschluss zwischen Sperrvorrichtung und der Sperrvorrichtungs-Ausnehmung bewirkt. Dieser Halte-Ring kann durch einen einfachen Gummiring ausgestaltet sein. Hierdurch wird weiterhin von Vorteil bewirkt, dass die Sperrvorrichtung immer in der Position verbleibt in die sie gerade gedreht wurde.Advantageously, between the locking device and the locking device recess, there is a retaining ring which is mounted in a groove on the locking device and which brings about a frictional connection between the locking device and the locking device recess. This retaining ring can be designed as a simple rubber ring. This also has the advantageous effect that the locking device always remains in the position into which it was just turned.

Von Vorteil ist die Sperrvorrichtung symmetrisch ausgestaltet und zwei gleichwirkende gegenüberliegend angeordnete Sperrvorsprünge sind vorhanden. Durch die Symmetrie ist nur eine Drehung um 90° notwendig um ein Lösen oder ein Festlegen zu erreichen. Dies ist angenehmer für einen Bediener als eine 180° Drehung.The locking device is advantageously designed symmetrically and there are two locking projections that have the same effect and are arranged opposite one another. Due to the symmetry, only a rotation of 90 ° is necessary to achieve a loosening or fixing. This is more convenient for an operator than a 180 ° turn.

Dem folgend ist nach einer Ausgestaltung der Erfindung vorgesehen, dass die Sperrvorrichtung eine nach außen gerichtete Eingriffsnut aufweist, vermittels welcher ein Werkzeug zur Drehung der Sperrvorrichtung ansetzen kann. So kann beispielsweise mit Hilfe einer Münze die Sperrvorrichtung ganz einfach zu öffnen oder zu schließen sein. Kein besonderes Werkzeug ist mehr erforderlich.According to one embodiment of the invention, it is provided that the locking device has an outwardly directed engagement groove by means of which a tool for rotating the locking device can be applied. For example, it can be very easy to open or close the locking device with the help of a coin. No special tools are required any more.

Bevorzugterweise ist zum nochmals vereinfachtem Zusammenbau eine Verdreh-Sicherung der Kammer in der Verschlusshülse vorgesehen, wobei ein an der Verschlusshülse ausgestalteter Vorsprung in eine entsprechende Ausnehmung an der Kammer im eingesteckten Zustand der Kammer in der Verschlusshülse eingreift.To further simplify assembly, a rotation lock of the chamber is preferably provided in the closure sleeve, a projection configured on the closure sleeve engaging in a corresponding recess on the chamber when the chamber is inserted in the closure sleeve.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen oder deren mögliche Unterkombinationen.Further advantageous refinements result from the further subclaims or their possible sub-combinations.

Fig. 1 zeigt einen beispielhaften Verschluss 1 einer Feuerwaffe mit erfindungsgemäßer Verriegelung einer Verschlusshülse 2 an einer Kammer 3 in zerlegtem Zustand. Fig. 1 shows an exemplary breech block 1 of a firearm with the inventive locking of a breech block 2 on a chamber 3 in a disassembled state.

Die Verriegelung der Verschlusshülse 2 erfolgt an einer Kammer 3, die ein Schlagstück 4 und eine einen Signalstift 7 umgebenden Schlagfeder 5 teilweise umschließt.The locking sleeve 2 is locked in a chamber 3 which partially encloses a striking piece 4 and a striking spring 5 surrounding a signal pin 7.

Dass die Kammer 3 immer in der richtigen Position in der Verschlusshülse 2 zum liegen kommt ist durch eine Verdreh-Sicherung der Kammer 3 in der Verschlusshülse 2 gewährleistet.The fact that the chamber 3 always comes to rest in the correct position in the closure sleeve 2 is ensured by the anti-twist protection of the chamber 3 in the closure sleeve 2.

Dabei greift ein an der Verschlusshülse 2 ausgestalteter Vorsprung 8 in Endlage der Verschlusshülse 2 zur Kammer 3 in eine entsprechende Ausnehmung 9 an der Kammer 3 im eingesteckten Zustand der Kammer 3 in der Verschlusshülse 2 ein. Der Vorsprung 8 an der Verschlusshülse 2 wird durch einen in der Vorsprungsöffnung 81 eingebrachten Stift gebildet.A projection 8 configured on the closure sleeve 2 engages in a corresponding recess 9 on the chamber 3 in the inserted state of the chamber 3 in the closure sleeve 2 in the end position of the closure sleeve 2 relative to the chamber 3. The projection 8 on the closure sleeve 2 is formed by a pin introduced into the projection opening 81.

In Fig. 2 ist die Kammer 3 aus Fig. 1 in einer schematischen Ansicht von unten gezeigt, sodass der Vorsprung 31 zu sehen ist, der mit der Sperrvorrichtung 6 interagiert.In Fig. 2 Chamber 3 is off Fig. 1 shown in a schematic view from below, so that the projection 31 can be seen, which interacts with the locking device 6.

Dementsprechend zeigt Fig. 3 eine Seitenansicht der Kammer 3 und des Vorsprungs 31 an dem der Verschlusshülse zugewandtem Ende der Kammer 3.Accordingly shows Fig. 3 a side view of the chamber 3 and the projection 31 at the end of the chamber 3 facing the closure sleeve.

In Fig. 4 ist eine schematische Seitenansicht auf die Verschlusshülse 2 gezeigt. Die die Sperrvorrichtung 6 aufnehmende Sperrvorrichtungs-Ausnehmung 22 als auch die Vorsprungsöffnung 81 zur Aufnahme des den Vorsprung 8 bildenden Stiftes sind ersichtlich. In Fig. 5 ist die Verschlusshülse 2 von oben gezeigt. Die Signalstiftöffnung 21 für den im gespannten Zustand des Verschlusses 1 herausragenden Signalstift 7 ist gut zu sehen.In Fig. 4 a schematic side view of the closure sleeve 2 is shown. The locking device recess 22 receiving the locking device 6 and also the projection opening 81 for receiving the pin forming the projection 8 can be seen. In Fig. 5 the closure sleeve 2 is shown from above. The signal pin opening 21 for the signal pin 7 protruding in the tensioned state of the closure 1 can be clearly seen.

In den Fig. 6 bis 9 ist die Sperrvorrichtung 6 in unterschiedlichen Ansichten gezeigt. Die Drehung der Sperrvorrichtung 6 um deren Drehachse D erfolgt durch einen formschlüssigen Eingriff eines Instruments, beispielsweise in Form einer kleinen Münze, in der Eingriffsnut 11. Durch die Drehung um 90° - siehe Fig. 8 - werden die gegenüberliegend symmetrisch ausgebildeten Sperrvorsprünge 61 von einer Öffnungsposition in eine Sperrposition gebracht. Die Nut 62 dient der Aufnahme des Halte-Rings 10 aus Fig. 10. Es handelt sich im Beispiel um einen einfachen Gummi-Ring.In the Figures 6 to 9 the locking device 6 is shown in different views. The rotation of the locking device 6 about its axis of rotation D takes place through a positive engagement of an instrument, for example in the form of a small coin, in the engagement groove 11. By the rotation through 90 ° - see Fig. 8 the oppositely symmetrical locking projections 61 are brought from an open position into a locking position. The groove 62 is used for receiving of the retaining ring 10 Fig. 10 . In the example it is a simple rubber ring.

In Fig. 9 sind die ebenfalls wieder an jedem Sperrvorsprung 61 symmetrisch gegenüberliegend ausgestalteten Vorrasten 63 zu sehen.In Fig. 9 the first catches 63, which are likewise configured symmetrically opposite one another on each locking projection 61, can also be seen.

Fig. 12 und 13 zeigen eine schematische Darstellung des zusammengesetzten Verschlusses 1 in einer Draufsicht und in einer Schnitt-Darstellung, wobei die Sperrvorrichtung 6 in geöffneter Stellung steht. Figures 12 and 13 show a schematic representation of the assembled closure 1 in a plan view and in a sectional representation, the locking device 6 being in the open position.

Die Verschlusshülse 2 umschließt die Kammer 3 teilweise und das herausragende Ende 51 der Schlagfeder 5 stützt sich an der Verschlusshülse 2 ab. Hierdurch wird die Vorspannung der Kammer 3 gegen die Verschlusshülse 2 erreicht.The closure sleeve 2 partially encloses the chamber 3 and the protruding end 51 of the striker spring 5 is supported on the closure sleeve 2. In this way, the pretensioning of the chamber 3 against the closure sleeve 2 is achieved.

Die Festlegung der Verschlusshülse 2 an der Kammer 3 erfolgt vermittels der an der Verschlusshülse 2 von einer Freigabelage zu einer Sperrlage drehbar gelagerten Sperrvorrichtung 6. Durch die einfache drehbare Lagerung ist die Verbindung einfach lösbar und wieder festlegbar.The locking sleeve 2 is fixed to the chamber 3 by means of the locking device 6, which is rotatably mounted on the locking sleeve 2 from a release position to a locking position. The simple rotatable mounting means that the connection can be easily detached and re-fixed.

Die Sperrvorrichtung 6 ist vermittels dem in ihrer Nut 62 gelagertem Halte-Ring 10 gegen die Sperrvorrichtungs-Ausnehmung 22 in Reibschluss gehalten.The locking device 6 is held in frictional engagement against the locking device recess 22 by means of the retaining ring 10 mounted in its groove 62.

Fig. 14 zeigt einen Schnitt durch die Verriegelung, wobei ein Vorsprung 31 an der Kammer 3 an einem Sperrvorsprung 61 an der Sperrvorrichtung 6 formschlüssig hintergreift, wenn dieser in die Sperrlage gedreht ist, gezeigt ist die geöffnete Stellung in der der Vorsprung 31 freigegeben ist. Die Verschlusshülse 2 könnte ganz einfach abgezogen werden, wobei die Federkraft der Schlagfeder 5 dies unterstützten würde. Fig. 14 shows a section through the lock, wherein a projection 31 on the chamber 3 engages behind a locking projection 61 on the locking device 6 in a form-fitting manner when this is rotated into the locking position, the open position in which the projection 31 is released is shown. The locking sleeve 2 could easily be withdrawn, the spring force of the mainspring 5 would support this.

Fig. 15 und 16 zeigen den Verschluss 1 in Blickrichtung XV bzw. Blickrichtung XVI aus Fig. 12. Fig. 15 and 16 show the closure 1 in viewing direction XV or viewing direction XVI Fig. 12 .

Dir Fig. 17, 18 und 19 zeigen analog zu den Fig. 12 bis 14 in schematischen Darstellungen die Verriegelung der Verschlusshülse 2 an der Kammer 3, wobei die Sperrvorrichtung 6 in der Stellung der Überwindung der Vorrast 63 durch den Vorsprung 31 an der Kammer steht. Die Überwindung der Vorrast 63 erfolgt entgegen dem noch ansteigendem Federdruck der Schlagfeder 5.to you Figures 17, 18 and 19 show analogous to the Figures 12-14 in schematic representations, the locking of the closure sleeve 2 on the chamber 3, the locking device 6 being in the position of overcoming the preliminary catch 63 by the projection 31 on the chamber. The preliminary detent 63 is overcome against the still increasing spring pressure of the striker spring 5.

Die Senke zwischen den Vorrasten 63 bildet dann eine sichere Lage, die in den Fig. 20 bis 22 genau gezeigt ist. In dieser Lage ist der Verschluss sicher geschlossen und die Verschlusshülse 2 sitzt in ihrer Endlage an der Kammer 3.The depression between the pre-latches 63 then forms a secure location that is in the Figures 20 to 22 is shown exactly. In this position, the closure is securely closed and the closure sleeve 2 is seated on the chamber 3 in its end position.

Das Seitenprofil der Sperrvorrichtung 6 ist so gewählt, dass sich nun der Außenkontur der Verschlusshülse 2 harmonisch anpasst. Es steht nichts mehr heraus. Siehe hierzu Fig. 23 in Blickrichtung des Laufs, entsprechend Fig. 16, dort mit geöffneter Sperrvorrichtung 6.The side profile of the locking device 6 is selected so that the outer contour of the locking sleeve 2 now adapts harmoniously. Nothing stands out anymore. See also Fig. 23 in the direction of view of the barrel, accordingly Fig. 16 , there with the locking device open 6.
