Abstract

The ignition pin (12) in its basic position extends over a rear face surface of the breechblock (11). The lock unit (10) comprises a housing (13), a striker hammer (14) pivotably located in the housing around a first axis (15), and a drive lever pivotably located on the first axis (15), which is pivotable in relation to the striker hammer and drives it on firing via a first stop. Between the drive lever and the striker hammer is inserted a set-back spring (19), which loads the striker hammer in the direction of the first stop. A striker bar (22) is linked to the drive lever spaced from the first axis. A pre-tensioned striker spring loads the striker bar in the direction of the ignition position of the striker hammer and is supported on the housing (14).

Description

Die vorliegende Erfindung betrifft eine Schlosseinheit für eine Pistole mit einem auf einem Griffstück verschiebbar geführten Verschluss, in welchem ein Zündstift verschiebbar gelagert ist, der in seiner Grundstellung eine hintere Stirnfläche des Verschlusses überragt.The present invention relates to a lock unit for a Gun with a slidably guided on a handle Closure in which an ignition pin is slidably mounted, which in its basic position is a rear face of the closure surmounted.

Aus der EP-A-0 013 583 ist eine Abzugvorrichtung bekannt, die ins Griffstück der Pistole eingebaut ist. Ein Schlaghammer ist um eine Achse schwenkbar. Auf derselben Achse ist ein Antriebsring schwenkbar, der gegenüber dem Hammer begrenzt schwenkbar ist. Der Ring ist durch eine Schlagfeder vorgespannt. Zwischen dem Ring und dem Schlaghammer ist eine weitere Feder eingesetzt. Die Abzugzunge wirkt mit einem Rasthebel zusammen, der in eine Raste des Rings eingerastet ist. Bei gespanntem Schlaghammer kann dieser entgegen der Kraft der zweiten Feder nach vorn verschwenkt werden, wo er mit einem Stift an einem Haken des Abzugmechanismus einrastet. Beim Ziehen der Abzugzunge wird zunächst der Stift freigegeben, so dass der Schlaghammer wieder in seine gespannte Lage zurückschnellt, bevor beim weiteren Betätigen der Abzugzunge der Ring freigegeben wird. Dadurch wird ein Double-Action-Abzug vermieden. In der nach vorn geschwenkten Grundstellung des Hammers sind allerdings beide Federn voll gespannt. Bei einem harten Schlag auf die Pistole, z.B. beim Fallen auf eine harte Unterlage, kann sich durch die Erschütterung ein Schuss auslösen, was gefährlich ist. Ausserdem wirkt sich die Erschütterung durch den Schlag des Rings auf den Hammer unmittelbar vor der Schussabgabe nachteilig auf die Treffsicherheit aus.From EP-A-0 013 583 a trigger device is known which is built into the pistol grip. A hammer is pivotable about an axis. On the same axis is a drive ring swiveling, the swiveling to a limited extent relative to the hammer is. The ring is biased by a striking spring. Between Another spring is inserted into the ring and the hammer. The trigger tongue interacts with a locking lever, which in one Notch of the ring is engaged. With a striking hammer this can be pivoted forward against the force of the second spring be where it is with a pin on a hook of the trigger mechanism locks. When pulling the trigger tongue is first the pen released so that the hammer back in its tense position snaps back before pressing the Trigger the ring is released. This creates a double action deduction avoided. In the basic position swiveled forward of the hammer, however, both springs are fully tensioned. at a hard blow to the pistol, e.g. when falling on one hard surface, a shock can result from the vibration trigger what is dangerous. In addition, the vibration affects by striking the ring on the hammer immediately in front firing adversely affects accuracy.

Die in den Figuren dargestellte Schlosseinheit 10 wird als Ganzes in den Pistolengriff 61 eines Griffstücks 60 der Pistole eingesetzt. Auf dem Griffstück 60 ist ein Verschluss 11 verschiebbar gelagert, in welchem der Lauf montiert ist. Im Verschluss 11 ist ein Zündstift 12 verschiebbar und durch eine Feder in seine in Figur 1, 2 und 5 gezeigte hintere Grundstellung vorbelastet, in welcher er eine hintere Stirnfläche 9 des Verschlusses 11 überragt. Die Schlosseinheit 10 hat ein Gehäuse 13. Im Gehäuse 13 ist ein Schlaghammer 14 um eine Achse 15 schwenkbar gelagert. Auf derselben Achse 15 ist ein Antriebshebel 16 schwenkbar. Die Schwenkbewegung des Hebels 16 gegenüber dem Hammer 14 ist durch zwei Anschlagflächen 17, 18 des Hammers 14 in beiden Schwenkrichtungen begrenzt. Der Hammer 14 ist gegenüber dem Hebel 16 durch eine Feder 19 nach hinten vorbelastet gegen die Anschlagfläche 17. Am Hebel 16 ist beabstandet von der Achse 15 eine Schlagstange 22 angelenkt. Die Stange 22 ist in einer Bohrung 23 eines Querstegs 24 des Gehäuses 13 geführt. Zwischen einer am Stangenende durch einen Querstift gesicherten Scheibe 25 und dem Steg 24 ist die vorgespannte Schlagfeder 26 eingesetzt, welche die Stange 22 auf Zug belastet. In der Grundstellung gemäss Figuren 1 bis 3 liegt eine Anschlagfläche 27 der Stange 22 am Steg 24 an. Die Schlagfläche 28 des Hammers 14 hat in dieser Grundstellung einen Winkel von etwa 15° gegenüber der hinteren Stirnfläche 9 des Verschlusses 11, damit, falls dieser durch einen Schlag nach hinten verschoben wird, der Hammer 14 nicht auf den Zündstift 12 aufschlagen kann. Der Hammer 14 ist mit einer Raste 31 in einer federbelasteten Fangklinke 29 eingerastet. Der Hebel 16 hat etwas Spiel gegenüber der Anschlagfläche 17.The lock unit 10 shown in the figures is a whole in the pistol grip 61 of a grip 60 of the pistol used. A closure 11 can be moved on the handle 60 stored in which the barrel is mounted. In the lock 11, an ignition pin 12 is displaceable and by a spring in its rear basic position shown in Figures 1, 2 and 5 preloaded, in which he has a rear end face 9 of the closure 11 towers. The lock unit 10 has a housing 13. In the housing 13, a hammer 14 is pivotable about an axis 15 stored. A drive lever 16 is located on the same axis 15 pivotable. The pivoting movement of the lever 16 relative to the hammer 14 is by two stop surfaces 17, 18 of the hammer 14 in limited in both directions. The hammer 14 is opposite the lever 16 biased backwards by a spring 19 the stop surface 17. On the lever 16 is spaced from the axis 15 a striker 22 articulated. The rod 22 is in one Bore 23 of a crosspiece 24 of the housing 13 out. Between a washer secured at the rod end by a cross pin 25 and the web 24, the prestressed striking spring 26 is used, which loads the rod 22 in tension. In the basic position according to Figures 1 to 3 is a stop surface 27 of the Rod 22 on web 24. The striking surface 28 of the hammer 14 has in this basic position an angle of about 15 ° with respect to rear end face 9 of the closure 11, so if this is pushed backwards by a blow, the hammer 14 cannot hit the ignition pin 12. The hammer 14 is engaged with a catch 31 in a spring-loaded catch pawl 29. The lever 16 has some play against the stop surface 17th

Der Hammer 14 wirkt in an sich bekannter Weise mit einer Abzugschiene 32 zusammen. Im Gehäuse 13 ist ein Schieber 33 verschiebbar gelagert, welcher die Schiene 32 durch eine Feder 34 in Eingriff in eine Raste 35 des Hammers 14 drückt. Auf einer Achse 44 ist zusätzlich ein Entspannhebel 36 schwenkbar gelagert. Mittels des Entspannhebels 36 kann der Hammer 14 aus der gespannten Stellung gemäss Figur 5 in die Grundstellung gemäss Figuren 1 bis 3 zurückverschwenkt werden. Am Gehäuse 13 ist zudem ein Auswerfer 37 befestigt, welcher nach der Schussabgabe die leere Patronenhülse durch eine Öffnung des Verschlusses 11 auswirft.The hammer 14 acts in a manner known per se with a trigger rail 32 together. A slide 33 is displaceable in the housing 13 which the rail 32 by a spring 34th engages in a detent 35 of the hammer 14. On a Axis 44 also has a release lever 36 pivotably mounted. The hammer 14 can be removed from the tensioned position according to Figure 5 in the basic position according to Figures 1 to 3 are pivoted back. On the housing 13 is also an ejector 37 attached, which after firing the shot the empty cartridge case through an opening of the closure 11 ejects.

Die dargestellte Schlosseinheit 10 funktioniert wie folgt: Wird die Abzugzunge gezogen, so wird die Schiene 32 nach vorn gezogen. Sie verschwenkt einen Sicherungshebel 42 (Figur 6), der ebenfalls um die Achse 15 schwenkbar ist und einen Sicherungsschieber 43 aus einer Sperraste 45 des Zündstifts 12 drückt, welcher durch eine Feder 46 nach unten belastet ist. Der Hebel 42 drückt die Fangklinke 29 nach vorn ausser Eingriff mit den Rasten 31, 38. Die Schiene 32 nimmt über den Eingriff in die Raste 35 den Hammer 14 mit gegen die Kraft der Feder 26 in die gespannte Lage nach Figur 5. Die Schiene 32 läuft einer Steuerkurve 47 entlang (Figur 6), welche sie gegen die Kraft der Feder 34 nach unten ausser Eingriff mit der Raste 35 verschiebt. Der Hammer 14 wird freigegeben, so dass die Feder 26 über die als Zugstange wirkende Schlagstange 22, den Hebel 26 und die Anschlagfläche 17 den Hammer 14 gegen den Verschluss 11 hin beschleunigt, bis die Fläche 27 am Steg 24 anschlägt. Durch die Massenträgheit des Hammers 14 dreht dieser weiter, schlägt auf den Zündstift 12 auf und löst den Zündvorgang aus. Nach der Schussabgabe gleitet der Verschluss 11 zurück, wobei die leere Patronenhülse ausgeworfen wird. Der eben beschriebene Vorgang wird mit "Double Action" (DA) bezeichnet. Wenn der Verschluss nach der Schussabgabe oder durch manuelles Bewegen nach hinten gleitet, schwenkt eine Steuerkurve des Verschlusses die Abzugschiene 32 nach unten und den Hammer 14 nach hinten, so dass dieser mit der Raste 38 an der Fangklinke 29 einrastet. Wenn die Abzugzunge losgelassen wird, gleitet die Schiene 32 nach hinten in Eingriff mit dem Hebel 42, der beim nächsten Betätigen des Abzugs nach Überschreiten der DA-Auslöseposition die Fangklinke 29 aus der Raste 38 drückt (Single Action).The lock unit 10 shown works as follows: Will the trigger tongue is pulled, the rail 32 is pulled forward. It pivots a locking lever 42 (FIG. 6) which is also pivotable about the axis 15 and a safety slide 43 presses out of a locking catch 45 of the ignition pin 12, which is loaded down by a spring 46. The lever 42 presses the catch pawl 29 out of engagement with the notches 31, 38. The rail 32 engages in the Locked 35 the hammer 14 against the force of the spring 26 in the tensioned position according to Figure 5. The rail 32 runs a control curve 47 along (Figure 6), which they against the force of the spring 34 moves down out of engagement with the detent 35. The hammer 14 is released so that the spring 26 over the acting as a pull rod 22, the lever 26 and the stop surface 17 accelerates the hammer 14 against the lock 11, until surface 27 strikes web 24. Through the Mass inertia of the hammer 14 continues to turn, opens the ignition pin 12 and triggers the ignition process. After Firing the slide slides back 11, the empty Cartridge case is ejected. The process just described is called "Double Action" (DA). If the clasp after firing the shot or by manually moving it backwards slides, a control curve of the lock swivels the trigger rail 32 down and the hammer 14 back so that this engages with the catch 38 on the catch pawl 29. If the Trigger tab is released, the rail 32 slides backwards engaged with the lever 42, the next time the Deduction of the catch pawl after exceeding the DA trigger position 29 pushes out of the catch 38 (single action).

In den Figuren 7 bis 9 ist die Funktion des Entspannhebels 36 dargestellt. Dabei zeigt Figur 7 den Entspannhebel 36 in der Grundstellung und den Schlaghammer 14 in seiner Sicherheitsstellung entsprechend Figuren 1 bis 3, in welcher die Fangklinke 29 in die Sicherheitsraste 31 eingerastet ist. Der Entspannhebel 36 hat einen Arm 48 mit einer vorstehenden Nase 49, die mit einer Gleitfläche 50 des Schlaghammers 14 zusammenwirkt. Vom Arm 48 steht eine Zunge 51 nach vorn ab. Beim Niederdrücken des Griffs 52 des Entspannhebels 36 stösst die Zunge 51 gegen einen Steg 53 der Fangklinke 29. Wenn der Schlaghammer 14 mit seiner Single-Action-Raste 38 an der Fangklinke 29 eingerastet ist, wird dabei die Fangklinke 29 ausser Eingriff mit dieser Raste 38 verschwenkt. Figur 8 zeigt diesen Vorgang unmittelbar vor der Freigabe des Schlaghammers 14. Beim weiteren Abschwenken des Entspannhebels 36 wird der Schlaghammer 14 freigegeben, so dass die Gleitfläche 50 auf die Nase 49 aufschlägt (Figur 9). Beim Zurückschwenken des Entspannhebels 36 wird der Schlaghammer 14 sanft zurückgeführt durch Gleiten der Nase 49 auf der Fläche 50 und gleichzeitig die Fangklinke 29 wieder freigegeben, so dass sie in der Raste 31 einrastet (Figur 7). FIGS. 7 to 9 show the function of the release lever 36 shown. 7 shows the release lever 36 in the Home position and the hammer 14 in its safety position corresponding to Figures 1 to 3, in which the catch pawl 29th is engaged in the safety catch 31. The release lever 36 has an arm 48 with a protruding nose 49 which with a Slide surface 50 of the hammer 14 cooperates. From arm 48 a tongue 51 protrudes forward. When depressing the Handle 52 of the release lever 36 pushes the tongue 51 against one Web 53 of the catch pawl 29. When the hammer 14 with his Single-action catch 38 is engaged on catch 29, the catch pawl 29 becomes disengaged from this catch 38 pivoted. Figure 8 shows this process immediately before Release of the hammer 14. When swiveling the Release lever 36, the hammer 14 is released so that the sliding surface 50 strikes the nose 49 (FIG. 9). At the The impact hammer 14 is pivoted backwards gently returned by sliding the nose 49 on the surface 50 and at the same time the catch pawl 29 released again, so that it engages in the catch 31 (FIG. 7).

The handle 60 has in the pistol grip 61 an inclined to the barrel axis magazine shaft 62 for inserting a magazine that is backed by a Rear wall 63 is completed. The continuing on the wall 63 two side walls 64 have parallel to the wall 63 in Cross-section of rectangular grooves 65. The lock unit 10 has the front edge on each side two molded, in the grooves 65 matching, laterally protruding rails 66. In two more Rails 67 on the upper edge of the housing 13 is the closure 11 out. The lock unit 10 is from above Inserted handle 60 and secured by two cross bolts 68, 69, through cross holes 70 to 72 in the two side walls 64 and in the housing 13 or recesses 73 in the housing 13 be pushed through. In Figure 10 is also the trigger tongue 74 indicated that in a front insert, not shown is pivotally mounted. The front insert also has lateral rails corresponding to the rails 67 for guiding the Closure 11. The trigger rail 32 is with the trigger tongue 74 pivotally connected.

Dadurch, dass die Schlagstange 22 die Federkraft durch Zug überträgt und sich der Kraftangriffspunkt der Schlagstange 22 gegenüber dem Schlaghammer 14 somit vor der Achse 15 befindet, baut die beschriebene Schlosseinheit schlanker als mit der bisher üblichen Druckübertragung und es werden optimale Antriebsverhältnisse erreicht, weil die Schlagstange 22 im Pistolengriff nach hinten unten geneigt eingebaut werden muss. Durch Integration des Schiebers 33 zur Abzugschiene 32 des Entspannhebels 36, des Sicherungshebels 42 und des Auswerfers 37 werden mehrere Funktionen in einer kompakten Einheit zusammengefasst, was die Herstellung vereinfacht.The fact that the impact rod 22 transmits the spring force by train and the force application point of the impact bar 22 opposite each other the hammer 14 is thus in front of the axis 15, builds the lock unit described is slimmer than with the previously usual Pressure transmission and there will be optimal drive conditions reached because the blow rod 22 in the pistol grip after must be installed inclined at the bottom rear. Through integration the slide 33 to the trigger rail 32 of the release lever 36, the Locking lever 42 and the ejector 37 have several functions summarized in one compact unit, what the manufacture simplified.

Dadurch, dass der Schlaghammer 14 in der Grundstellung in der Sicherungsraste 31 eingerastet und die Schlagstange 22 gegen den Anschlag 24 angeschlagen ist, wird eine mehrfache Sicherung gegen eine unbeabsichtigte Schussabgabe erreicht. Eine erste Sicherung ist die zuvor erwähnte Sicherung durch die Neigung der Schlagfläche 28. Eine zweite Sicherung ist die Zündstiftsicherung durch den Sicherungsschieber 43. Eine dritte Sicherung ist durch den Entspannhebel 36 gegeben. Falls der Schütze den Schlaghammer dadurch entspannt, dass er ihn zurückhält, den Abzug betätigt und den Schlaghammer 14 dann langsam zurückführt, wird der Schlaghammer 14 nach Loslösen des Abzugs automatisch in die Sicherungsraste 31 zurückgeführt. Weil die Schlosseinheit 10 als vormontierte Einheit ins Griffstück 60 eingesetzt ist, kann sie leicht gegen eine andere Schlosseinheit 10 ausgetauscht werden, z.B. zu Reparaturzwecken. Es ist auch möglich, mehrere unterschiedliche Schlosseinheiten 10 bereitzustellen, z.B. zusätzlich zur beschriebenen eine ohne die Raste 38, so dass die Pistole eine Double-Action-Only-Pistole ist. Auch können für unterschiedliche Munitionsarten Schlosseinheiten mit unterschiedlicher Schlagkraft zur Verfügung gestellt werden. Die beschriebene Schlosseinheit ermöglicht also auch die leichte Anpassung an unterschiedliche Bedürfnisse.The fact that the hammer 14 in the basic position in the Locking catch 31 engaged and the striker bar 22 against the Stop 24 is struck, a multiple backup against an unintentional shot fired. A first backup is the previously mentioned backup by the inclination of the Striking surface 28. A second fuse is the ignition pin fuse by the safety slide 43. A third fuse is given by the release lever 36. If the shooter Percussion hammer relaxed by holding it back, the trigger actuated and then slowly returns the hammer 14, the hammer 14 is automatically in after releasing the trigger the safety catch 31 is returned. Because the lock unit 10 is used as a pre-assembled unit in the handle 60, can they can easily be exchanged for another lock unit 10, e.g. for repair purposes. It is also possible to have several different ones To provide lock units 10, e.g. additionally to the one described without the detent 38 so that the gun is a double-action-only pistol. Can also be used for different Ammunition types lock units with different Clout can be made available. The one described The lock unit also enables easy adjustment to different needs.
