Description

The invention relates to a catch lever for a trigger device of a closure and a security device having firearm, in particular rapid firearm, wherein the catch lever between a lock arresting the locking position and a lock not arresting position is adjustable.

Such a catch is from the DE 101 63 003 known.

Locations such as "top", "bottom", "left", "right", "front" and "rear" are from the point of view of the shooter for a weapon in the normal attack, firing horizontally to "front".

• Unterhalb der Bewegungsbahn des Verschlusses (nicht dargestellt) befindet sich ein Griffstück, in dem ein Abzug (a) schwenkbar gelagert ist. Dessen quer verlaufende Schwenkachse befindet sich im oberen Mittelbereich des Abzugs, so daß der hintere, obere Abzugsteil beim Betätigen des Abzugs eine Kurvenbahn nach oben zurücklegt. Dieser hintere, obere Teil des Abzuges wirkt auf das vordere Ende eines Fanghebels (f) ein, der seinerseits, um eine Querachse schwenkbar, im Waffengehäuse oder im Griffstück angebracht ist. Das hintere Ende des Fanghebels (f) ist als Abzugsstollen (s) ausgebildet. Wenn der Abzug (a) von einer Feder in seine Ruhelage nach vorne geschwenkt ist, dann schwenken das vordere Ende des Fanghebels (f) - ebenfalls unter Federwirkung - nach unten, und dessen hinteres Ende mit dem Abzugsstollen (s) nach oben. Diese Lage des Abzugsstollens ist die Arretierlage (siehe Fig. 8). Abzug (a) und Fanghebel (f) können jeweils von einer eigenen oder einer gemeinsamen Feder abgefedert bzw. vorgespannt sein und werden von dieser in ihre Ruhelage (Abzug) bzw. ihre Arretierlage (Fanghebel) gedrückt.

Rapid firearms, such as submachine guns or machine guns, which are designed to deliver sustained fire, have a fairly simple trigger mechanism, of which a representative example based on the 8 and 9 is described:

• Below the path of movement of the closure (not shown) is a handle in which a trigger (a) is pivotally mounted. Whose transverse pivot axis is located in the upper central region of the trigger, so that the rear, upper trigger member when pressing the trigger travels a curved path upwards. This rear, upper part of the trigger acts on the front end of a catch lever (f), which in turn is mounted, pivotable about a transverse axis, in the weapon housing or in the handle. The rear end of the catch lever (f) is designed as a sear (s). When the trigger (a) is pivoted forward by a spring to its rest position, then pivot the front end the catch lever (f) - also under spring action - down, and its rear end with the sear (s) to the top. This position of the trigger lug is the locking position (see Fig. 8 ). Trigger (a) and catch lever (f) can each be cushioned or biased by its own or a common spring and are pressed by this in their rest position (trigger) or their locking position (catch lever).

Now, if the closure is withdrawn from its front rest position, then it moves with its underside the sear (s) and thus the rear end of the catch lever (f) down while he runs over the sear (s). When a detent lug formed on the underside of the closure has passed over the sear (s), it snaps up and underlies the detent lug. The weapon is now excited and ready to fire.

When the trigger (a) is operated, the sear (s) lowers until it releases the lug; the lock is released and the gun starts with continuous fire. If the trigger (a) is released, then the sear (s) jumps back up into its locking position, behind the latching lugs and keeps the shutter in its fire ready position (rear position). The sustained fire breaks off.

As a backup, a pure trigger guard is often used, although precludes the unintentional actuation of the trigger, but not a yielding of the Abzugssstollens due to acceleration forces, for example, when the loaded, tensioned and deducted machine gun falls from a truck.

Therefore, there are also fuses (w), which additionally or solely set the catch lever (f) on a securing finger (i) in its locking position. But this has the disadvantage that the lock with a secured weapon can not be withdrawn via the locked catch (f) or can jam on the catch (f), because the latter can not escape. A backup roller (w), which with its peripheral surface a securing finger (i) of the catch lever (f) assumes, shows Fig. 8 , A weapon with such a fuse (w) can not be charged in the locked state.

Fully automatic weapons, which work according to the functional principle described above, are increasingly used in so-called weapon stations. In these, the lafettierten weapons are remotely aligned via actuators and actuated by acting on trigger and safety device actuators (e.g., electromagnetic). In order to provide the greatest possible security here as well, these actuators are designed in such a way that, in the event of malfunctions (for example power failure), the triggering operation is interrupted and the safety device is set to "safe" irrespective of the state of the weapon.

In addition to the problem described above (no load through with secured weapon), the further malfunction may occur here that the weapon fires uncontrollably even with interrupted trigger operation. High actuating forces of the actuator for the safety device can cause the fuse to jam the securing finger (i) in the catching lever (f) in such a way that the sear (s) remains out of engagement with the latching lug on the closure. This malfunction may occur when the shutter is back on its way forward immediately after the trigger operation, and a power failure causes the trigger to be released at the same time and the actuator acting on the fuse places it in its "safe" position. Position presses. In In this weapon condition, the catch lever (f) and the sear (s) are in their release position, and the securing finger (i) dips into the securing recess on the securing device (here: the backup roller (w)). Now, if the actuator, the backup roller (w) in the direction of "safe" blocks the locking finger (i) whose travel and the edge of the securing recess is so tight against the safety finger (i) pressed so that the catch (f) despite spring action not can move into its locking position. The catch lever (f) is jammed over the securing finger (i) and the catch moves freely firing back and forth until the ammunition supply is interrupted (see Fig. 9 ).

Based on this problem situation, there are trigger devices in which the sear is formed on a catch catch pivotable on the catch lever (see eg DE 101 63 003 A1 and US 2004/0194615 A1 respectively. US 6,907,813 B2 ). When returning the closure this sling pawl is pivoted from its locking position against the force of a spring in an evasive position in which it can be overflowed by the closure. With leading closure of the sear of the sear falls under spring action in the detent lugs and is then additionally held by the shutter in this locking position. At the sear additionally a securing element is provided, which cooperates with the securing device (for example, a backup roller) so that it always - regardless of the position of the closure or the catch lever - can be brought into their secure position. The safety device can act both on the trigger and on the catch lever.

In this extraction device, an additional spring element is required to ensure the locking function, and the sling and the pivoting suspension must be the full Pick up the force of the leading shutter. The relatively small catch and its suspension are exposed to high dynamic loads. Any breakage or failure of the sling, its suspension in the catch lever and / or the spring element in the worst case so affect the weapon function that the weapon fires regardless of the position of the fuse and the trigger until the entire ammunition is fired , In addition, the force of the spring element must be matched exactly to the force acting on the catch spring force. Otherwise, the catch passing over the catch also pushes the catch lever down into the handle. This may interfere with the interaction of the fuse element with the backup roller.

In contrast, the invention provides an improved catch lever and that with the subject of the present claim 1, ie with a catch lever with the features mentioned, in which the catch lever has a securing element which adjustable relative to the catch lever against a spring force from a rest position to a backup position is.

The fuse element takes its backup position in auflaufendem on the catch lever or on this adjacent closure, when the closure on the securing element in the forward direction exerts a force (and adjusted in the security position). In this position (the backup position), the securing element engages the securing device, if this simultaneously assumes its safe position, and sets the catch lever itself in its locked position.

Otherwise, however, the securing element assumes its rest position (II) and releases the catch lever, regardless of the position of the securing device.

In this solution, the functions "locking the shutter by the catch lever" and the actual backup function "fixing the catch lever in the locking position" constructively independent, so that each component or component (here: the catch and the fuse element) optimal for its task can be designed and designed.

The catch lever can be robust and stable designed for the high stresses that occur when interacting with the closure, while the fuse element must not bear high mechanical stress through the closure, but can be designed especially in terms of reliable interaction with the security device.

At the same time this arrangement allows actuation of the safety device in any functional state of the weapon, without components of the fuse element and the actual safety device collide with each other.

Furthermore, the catching function of the stable sear stroke on the catch lever is not impaired in case of a malfunction of the securing element. That is, the risk of unchecked continued shooting weapon, in which the trigger is not operated, is largely excluded compared to the known from the prior art solutions, at least significantly reduced.

Finally, a weapon with such a catch lever can also be loaded in the secured state, and the safety device of the weapon is effectively operable in any functional condition.

By the action of a spring ensures that the adjustable locking element occupies either its rest position (due to the spring effect) or under the action of the closure against spring force its backup position. Intermediate positions, which possibly impair the function, are thus avoided.

The securing element has an actuating element, which cooperates with the closure and over which it is adjustable in its securing position, and a securing part which acts on the securing device. Control element and security part can be designed and arranged as required for their respective function (claim 2).

In accordance with claim 3, the securing element (101, 201) is arranged in the region of a draw-off lug (31) formed on the catch lever (21) and engaging in the locking position on the closure. Such a sear is particularly suitable to attack stably at the closure. The arrangement of the securing element in this area, the closure with the same effective areas, which allow its locking on the sear or on the catch lever, the adjustment of the securing element (101, 201) effect in the securing position.

Due to the development according to claim 4, the reliability of the security element is increased again by the stress of the actuating element is reduced. This is achieved by the fact that the control element is located in fitting trim inside the sear profile. The blocking or locking function is exercised on the closure exclusively via the sear; the securing element experiences no additional loads and in particular does not absorb any loads applied by the closing spring via the closure to the catch lever or the sear.

The design of the fuse element as a slide according to claim 5 allows a functionally reliable, shielded arrangement of the fuse element in the catch lever. Preferably, the sliding direction is approximately in the direction of the closure, whereby the stress of the fuse element can be kept as low as possible when actuated by the shutter.

The claims 6 to 9 relate to an embodiment in which the securing element is designed as a pivot lever.

The pivot axis extends transversely to the direction of the closure (claim 6). This also runs for the pivot lever, the actuating direction according to the direction of the closure.

Due to the design as a two-armed pivoting lever according to claim 7, the actuating direction (the auflaufenden closure) can be deflected in a different direction of securing the second lever arm. For this purpose, the two lever arms, for example, form an angle to each other. Thus, certain structural boundary conditions, which may be predetermined by the safety device, can be flexibly taken into account.

If the lever arms have different lengths, as indicated in claim 8, the travel and the securing travel can also be of different lengths. In particular, when the actuator having the first lever arm is shorter than the second lever arm having the securing part, the travel can be comparatively short and the required safety path can be made so long by the appropriate choice of leverage that sufficiently large distances are available, around the effective range of the safety device to leave or to get into this. Thus, the securing part with respect to the required active surfaces and its mechanical stress correspondingly large or stable be formed.

Is the pivot axis according to claim 9 through the center of gravity of the pivot lever, so this is dynamically balanced, i. Transverse accelerations acting on the weapon can not bring the pivoting lever out of its securing position.

The design of the relevant for the securing effect effective surfaces on the securing part or the corresponding counter surface on the securing device according to claim 10 further increases the securing effect. The self-locking design prevents - even with a high load of the sear against the securing effect - the effective surface of the security part and the counter surface of the security device can slide off each other and so the backup function can be disturbed. Such loads can occur, for example, at high dynamic loads (blows) on the weapon or when the trigger with high force against the securing effect should act on the catch lever; for example, when the trigger is operated by a motor against the securing device.

Claim 11 relates to a trigger device with a catch lever according to the invention.

The claim 12 relates to a handle with a trigger device according to the invention, which can be replaced, for example, with appropriate design against a conventional handle without the specified security functions. Is the handle as defined in claim 13 provided with one or more interfaces, via which the trigger or the securing device with an actuating element can be coupled to their operation, a weapon with such a handle can be particularly easily used in a so-called weapon station.

Claim 14 finally relates to a weapon with a catch lever according to the invention, a trigger device according to the invention or a handle according to the invention.

Structure and function of the catch lever 21 and the trigger device according to the invention are in connection with the Fig. 1 (First embodiment) and 2 to 7 (second embodiment) explained with reference to two embodiments. The same reference numerals apply to the same components.

According to Fig. 1 the handle 1 is attached to a non-illustrated housing of a weapon, in which a trajectory for the shutter 3 partially shown is defined. The trajectory of the closure runs along the axis of the soul. 5

The handle has at its front a trigger guard 7, in which from the top of the handle 1, a trigger 9 dips, which is pivotally mounted about a transverse axis of the axis 5 to the trigger axis 11 in the handle 1. A leg spring 13, whose two legs surround a transverse pin 17, and which is fixed in the handle 1, pushes the trigger 9 with its lower spring leg 15 forward. The upper spring leg 19 presses a two-armed catch lever 21 at its rear lever arm 23 attacking counterclockwise upwards in its locking position. The front lever arm 25 extends above the trigger axis 11 and a trigger roller 27, which sits on the trigger 9. The catching lever 21 itself is pivotally mounted in the handle 1 on a lever axis 29 running transversely to the axis of the soul 5.

If the trigger 9 is actuated while pivoted against the force of the leg spring 13 counterclockwise, then the trigger roller 27 raises the front lever arm 25 against the force of the leg spring 13 and lowers the end of the rear lever arm 25 (this position is in Fig. 4 shown in connection with the second embodiment). At the rear end of the rear lever arm 23, a sear 31 is shown, which represents a detent lug 33 on the closure 3 and this holds in its cocked fireproof position ( Fig. 1 ). When lowering the sear 31 through the trigger movement of the shutter 3 is released, then moves under the influence of the shutter spring not shown in the weapon housing forward, leads to the ammunition and finally ignites (with the help of the not shown Firing pin) the propellant charge (see position Fig. 4 ).

When lowering the rear end 23 of the catch lever 21 whose front end 21 is raised and engaged at a catch catch 51 provided there by a release latch 53. The release latch 53 is suspended by a pin 54 against the force of a pawl spring 55 pivotally on the trigger 9. After releasing the trigger, the release latch 53 holds the rear end 23 and the sear 31 of the catch lever 21 outside the path of movement of the shutter (position Fig. 5 ).

Only when the shutter 3 runs backwards, he meets the trigger pawl 53 and pivots it in a clockwise direction against the force of the pawl spring 55 and releases the catch 51 on the catch lever 21 which counterclockwise with its rear end 23 in the path of movement Closure 3 jumps (see Fig. 6 ). In this case, the one or more locking lugs 33 of the closure 3 successively overflows the sear 31, which dives resiliently down into the handle (see Fig. 7 ), until the foremost detent lug 33 on the closure 3 has completely overflowed the sear 31, the catch lever 21 assumes its locking position and the sear 31 engages behind the detent lug 33 and can attack the closure in the rearmost position.

In the withdrawal device of the first embodiment ( Fig. 1 ) is arranged in the rear end of the rear lever arm 23, a slider 101, the rear end face 103 forms an actuating element on which the adjacent detent lugs 33 can engage. In its rest position (II), the slider 101 is under the action of a running inside the rear lever arm 23 spring assembly 104 by the amount D backwards out of the rear lever arm 23 out.

The latching lug 33 of the closure 3 pressing against the rear end face 103 of the slide 101 from behind displaces the slide 101 against the action of the spring arrangement 104 approximately in the direction of the core axis 5 by the amount D in the rear lever arm 23 into the securing position I of the slide. In this position, the rear end face 103 closes with the rear end face of the sear 31, so that the actuating element lies completely within the sear profile. The rear end face of the sear 31 prevents the closure from moving further forward when the sear 31 is in its locked position (see FIG Fig. 1 . 2 and 3 ). At the same time it is ensured that the slider 101 itself is only slightly burdened by the leading or adjacent closure 3. The load of the slider 101 itself results only from the restoring force of the spring assembly 104, which must be overcome by the leading closure 3. The substantial load and stress through the closure 3, however, experiences the sear 31 or the catch lever 21. Thus, the risk of overloading or malfunction of the slider 101 is minimized.

The slider 101 has from the adjusting element (here: its rear end face 103) starting from a downwardly extending finger 105, which forms a securing part and cooperates with a securing device 40. The illustrated securing device 40 comprises a securing roller 41, which is provided with a recess 43. Rotationally fixed to the backup roller 41, a latching tab 45 and a protruding from the housing (not shown) actuating lever is connected, via which the backup roller 41 between the "safe" - and the firing position can be rotated. These two positions are by two recesses 49 on the latching tab 45 and a fixedly arranged resilient latching arrangement 47 defined, which engages in one of the two recesses 49.

In addition, the locking tab 45 has a securing lug 46. When the safety device is in its "Safe" position (position in Fig. 1 ), the securing lug 46 behind a corresponding securing extension 10, which projects from the trigger 9 to the rear in the housing 1.

• Bei durchgeladener Waffe liegt der Verschluß 3 mit seinem Raststollen 33 an der hinteren Stirnfläche des Abzugsstollens 31 und der hinteren Stirnfläche 103 des Schiebers 101 an, der die Sicherungslage (Lage I) einnimmt. Der Finger 105 befindet sich hier im Wirkbereich der Sicherungseinrichtung 40. Die Ausnehmung 43 in der Sicherungswalze 41 befindet sich in der "Sicher"-Stellung (Stellung A). Der Finger 105 liegt mit seiner Wirkfläche 105a an der äußeren Umfangsfläche der Sicherungswalze 41 an. Damit stützt der Schieber 101 den hinteren Hebelarm 23 und damit den Abzugsstollen 31 nach unten gegen die Sicherungswalze 41 ab. Der Abzugsstollen kann nicht aus seiner Arretierlage gebracht werden; selbst dann nicht, wenn die zusätzliche Abzugssicherung, die durch die Sicherungsfahne 46 und den Sicherungsfortsatz 10 gebildet wird, wegfallen würde und der Abzug 9 betätigt würde.
• Wird nun die Sicherungseinrichtung 40 durch Verdrehen der Sicherungswalze 41 in ihre "Feuer"-Stellung gebracht, nimmt die Ausnehmung 43 die Stellung B ein und befindet sich im Bereich des Fingers 105; gleichzeitig nimmt die Sicherungsfahne 46 eine außerhalb des Wirkbereichs des Sicherungsfortsatzes 10 liegende Position ein (in Fig. 1 nicht dargestellt, siehe analog Fig. 3).

• Wird nun der Abzug 9 betätigt, wird über die Abzugsrolle 27 der vordere Hebelarm 25 des Fanghebels 21 im Uhrzeigersinn nach oben gedrückt und der hintere Hebelarm 23 mit dem Abzugsstollen 31 und dem Schieber 101 nach unten in das Gehäuse 1 verschwenkt. Dabei tritt der Finger 105 in die Ausnehmung 43 in der Sicherungswalze 41 ein, der Verschluß 3 wird freigegeben und bewegt sich nach vorne (siehe analog Fig. 4).
• Dabei wird der vordere Hebelarm 25 mit der Fangrast 51 in der Auslöseklinke 53 gefangen, so daß der Fanghebel 21 mit dem Abzugsstollen 31 bei freigegebenem Abzugs 9 innerhalb des Griffstücks 1 bleibt (diese Stellung ist analog in Fig. 5 dargestellt).
• Der Schieber 101 nimmt seine Ruhelage ein, in der dessen hintere Stirnfläche 103 nach hinten aus dem Abzugsstollen 31 heraussteht und der Finger 105 außerhalb des Wirkbereichs der Sicherungseinrichtung 40 verläuft (Lage II, in Fig. 1 durchgezogen dargestellt).
• Bei normaler Waffenfunktion führt der sich nach vorne bewegende Verschluß 3 eine neue Patrone zu, wird danach durch den beim Abfeuern entstehenden Rückstoß wieder nach hinten geschleudert und löst dabei die Auslöseklinke 53 aus, welche die Fangrast 51 freigibt. Dadurch bewegt sich - unter der Wirkung des oberen Federschenkels 19 der Schenkelfeder 13 - der Fanghebel 21 mit seinem hinteren Hebelarm 23 nach oben. Der rücklaufende Verschluß 5 verschiebt dabei den hinteren Hebelarm 23 wieder nach unten und zwar über entsprechend ausgebildeten Anlaufschrägen 32, die etwa von der Raststollenkante schräg nach hinten oben verlaufen. Dabei wird die Verschlußfeder soweit gespannt, bis sich die Bewegung des Verschlusses 3 wieder umkehrt und sich der Raststollen 33 an die hintere Stirnfläche des Abzugsstollens 31 anlegt und dabei den Schieber 101 an seiner hinteren Stirnfläche 103 nach vorne in den hinteren Hebelarm 23 hinein verschiebt.
• Bei einer Fehlfunktion (Fehlzündung, Funktionsstörung beim Vorlauf, etc.) läuft der Verschluß 3 nicht zurück, sondern bleibt zwischen Abzugsanordnung und Patronenlager. Auch in diesem Fall kann die Sicherungseinrichtung 40 betätigt werden, da sich der Finger 105 in seiner Ruhelage II außerhalb des Wirkbereichs der Sicherungswalze 41 befindet. Der Schieber 101 behindert die Betätigung der Sicherungseinrichtung 40 nicht. Die Sicherungseinrichtung 40 kann aus der "Feuer"- in die "Sicher"-Stellung verstellt werden.
• Um die Fehlfunktion zu beheben, wird der Verschluß manuell zurückgeführt (durchgeladen). Beim Durchladen wird ebenfalls die Auslöseklinke 53 betätigt und der hintere Hebelarm 23 taucht mit dem Abzugsstollen 31 aus dem Gehäuseprofil nach oben in die Bewegungsbahn des Verschlusses. Das Durchladen ist auch in der "Sicher"-Stellung der Sicherungseinrichtung 40 möglich, da sich der Schieber 101 mit dem Finger 105 in seiner Ruhelage II außerhalb des Wirkbereichs der Sicherungseinrichtung 40 befindet und die beim Durchladen auf den hinteren Hebelarm 23 ausgeübte Absenkbewegung von der Sicherungswalze 41 nicht behindert wird.
• Nach dem Durchladen liegt der Raststollen 33 des Verschlusses 3 wieder am Abzugsstollen 31 des Fanghebels 21 an, nachdem er zuvor den Schieber 101 an der hinteren Stirnfläche 103 angreifend in den Fanghebel 21 hinein in seine Sicherungslage I verschoben hat. Der Finger 105 (in seiner Sicherungslage in Fig. 5 gestrichelt dargestellt) befindet sich im Wirkbereich der Sicherungseinrichtung 40 und die Waffe befindet sich sofort im gesicherten Zustand.
• Nun können gefahrlos alle notwendigen Arbeiten im vorderen Bereich der Waffe durchgeführt werden, ohne daß sich der Verschluß 3 durch versehentliches Betätigen des Abzugs 9 lösen kann.
• Über den relativ zum Abzugsstollen 31 verstellbaren Schieber 101 mit dem an der Sicherungseinrichtung 40 angreifenden Finger 105 wird folgendes sichergestellt: Zum einen kann die Waffe auch in gesichertem Zustand durchgeladen werden kann, da sich der Schieber 101 mit dem Finger 105 erst dann im Wirkbereich der Sicherungseinrichtung 40 befindet, wenn der Verschluß 3 mit seinem Raststollen 33 die hintere Stirnfläche 103 des Schiebers 101 soweit in den Fanghebel 21 geschoben hat bis diese bündig mit der hinteren Stirnfläche des Abzugsstollens 31 abschließt und der Raststollen 33 somit am Abzugsstollen 31 anliegt. Zum anderen kann die Waffe in jedem Zustand gesichert werden kann, selbst dann, wenn sich der Verschluß 3 vor dem Griffstück befindet und sich der hintere Hebelarm 23 abgesenkt im Griffstück 2 befindet, da der Schieber 101 in seiner Ruhelage II mit dem Finger 105 außerhalb des Wirkbereichs der Sicherungseinrichtung 40 verläuft.

The slider 101 interacts with the securing device 40 via its finger 105 as follows:

• When loaded weapon is the shutter 3 with its detent lug 33 on the rear end face of the sear 31 and the rear end face 103 of the slider 101, which occupies the backup position (position I). The finger 105 is here in the effective range of the securing device 40. The recess 43 in the securing roller 41 is in the "safe" position (position A). The finger 105 rests with its active surface 105 a on the outer peripheral surface of the securing roller 41. Thus, the slider 101 supports the rear lever arm 23 and thus the sear 31 down against the backup roller 41 from. The sear can not be removed from its locked position; not even if the additional trigger safety, which is formed by the securing lug 46 and the securing extension 10, would be omitted and the trigger 9 would be actuated.
• If now the securing device 40 is brought into its "fire" position by turning the securing roller 41, the recess 43 assumes the position B and is located in the region of the finger 105; At the same time, the securing lug 46 takes one outside the effective range the securing extension 10 lying position (in Fig. 1 not shown, see analog Fig. 3 ).

• Now, if the trigger 9 is actuated, the front lever arm 25 of the catch lever 21 is pressed clockwise upward on the take-off roller 27 and the rear lever arm 23 is pivoted with the sear 31 and the slider 101 down into the housing 1. The finger 105 enters the recess 43 in the backup roller 41, the shutter 3 is released and moves forward (see analog Fig. 4 ).
• In this case, the front lever arm 25 is caught with the catch 51 in the release latch 53, so that the catch lever 21 remains with the sear 31 with the trigger 9 released within the handle 1 (this position is analogous to Fig. 5 shown).
• The slider 101 assumes its rest position, in which its rear end face 103 protrudes to the rear from the sear 31 and the finger 105 extends outside the effective range of the securing device 40 (position II, in FIG Fig. 1 shown in solid lines).
• In normal weapon function, the forward moving shutter 3 introduces a new cartridge, is then thrown backwards by the recoil resulting from the firing and thereby triggers the triggering pawl 53, which releases the catching catch 51. This moves - under the action of the upper spring leg 19 of the leg spring 13 - the catch lever 21 with its rear lever arm 23 upwards. The returning shutter 5 shifts the rear lever arm 23 back down and that over appropriately trained run-off slopes 32, approximately from the Latch peg edge sloping back upwards. In this case, the closure spring is stretched until the movement of the closure 3 is reversed again and the detent lugs 33 applies to the rear end face of the Abzugssstollens 31 while the slider 101 moves at its rear end face 103 forward in the rear lever arm 23 into it.
• In a malfunction (misfire, malfunction in the flow, etc.), the shutter 3 does not run back, but remains between the trigger assembly and chamber. Also in this case, the securing device 40 can be actuated, since the finger 105 is in its rest position II outside the effective range of the backup roller 41. The slider 101 does not hinder the operation of the securing device 40. The securing device 40 can be moved out of the "fire" position into the "safe" position.
• To fix the malfunction, the shutter is returned manually (loaded). When loading is also the trigger pawl 53 is actuated and the rear lever arm 23 dives with the sear 31 from the housing profile upwards in the movement path of the closure. The loading is possible even in the "safe" position of the securing device 40, since the slider 101 is located with the finger 105 in its rest position II outside the effective range of the securing device 40 and the load exerted on the rear lever arm 23 during lowering of the backup roller 41 is not obstructed.
• After loading the latching lug 33 of the shutter 3 is again on the sear 31 of the catch lever 21 after he previously the slider 101 at the rear End face 103 has attacking in the catch lever 21 has moved into its backup position I. The finger 105 (in its backup position in Fig. 5 dashed lines) is in the effective range of the securing device 40 and the weapon is immediately in the secure state.
• Now all the necessary work in the front of the weapon can safely be performed without the shutter 3 can solve by accidentally pressing the trigger 9.
• About the relative to the sear 31 adjustable slider 101 with the attacking on the securing device 40 finger 105 ensures the following: First, the gun can be loaded in a secure state, since the slider 101 with the finger 105 only in the effective range of the security device 40 is when the shutter 3 with its locking lug 33, the rear end face 103 of the slider 101 has pushed so far into the catch lever 21 until it is flush with the rear end face of the sear 31 and the latching lugs 33 thus abuts the sear 31. On the other hand, the weapon can be secured in any condition, even if the shutter 3 is in front of the handle and the rear lever arm 23 is lowered in the handle 2, since the slider 101 in its rest position II with the finger 105 outside of the Effective range of the securing device 40 runs.

In the in the Fig. 2 to 7 shown second embodiment, a two-armed pivot lever 201 is provided instead of the slider 101, which is a transverse to the axis of the axis 5 pivot axis 202 in the rear lever arm 23 of the Fang lever 21 is arranged. An upper lever arm 203 of the pivot lever 201 forms with its rear end face the actuator to which the locking lug 33 adjusted at Abzugsstollen 31 closure 3, the pivot lever 201 against the force of a spring assembly 204 in the backup position, so that a lower lever 205 of the Swing lever 201 as a securing part in the effective range of the securing device 40 moves (see FIGS. 2 and 3 ). In this position, the upper pivoting lever arm 203 completely immersed in the profile of the draw-off lug 31st

If the shutter 3 with its detent lug 33 is not on the sear 31, the pivot lever 201 under the action of the spring assembly 204 assumes its rest position, in which the lower lever arm 205 is outside the effective range of the securing device 40 and the upper lever arm 203 partially backwards out of the Profile of the sill protrudes ( Fig. 4-7 ).

The functionality of this safety device is analogous to the safety device described in connection with the first embodiment. With the pivot lever 201, however, very short travel paths of the upper lever arm 203 can be realized by the lower lever arm 205 is formed longer than the upper lever arm 203. A short pivoting of the upper lever arm 203 causes a long pivoting path of the lower lever arm 205 out.

The travel can be so short that the overlap with the detent lug 33 of the returning shutter 3 only minimally compared to a catch lever (f) without pivot lever 21 - 8 and 9 shown - extended to the rear. Thus, the closure assembly according to Fig. 2-7 without further adjustments against the in 8 and 9 Shutter assembly shown be replaced. Conveniently, only the handle must be replaced.

In the embodiments described above, the securing device is designed as a rotatable securing roller 41 with corresponding recesses 43. There are other embodiments in which the securing device is designed as a sliding safety, in which a corresponding securing profile is formed either transversely to the axis of the soul 5 or parallel to the axis of the soul 5. Such a safety slide then has a corresponding securing profile with recesses and active surfaces, which cooperates analogously to the described backup roller 41 with the fuse element 21 arranged on the fuse element (for example, a slider 101 or a pivot lever 201). Such a safety slide can also be coupled directly with a corresponding actuator or an actuator which controls the weapon, for example, in a weapon station. There are also embodiments in which 9 separate interfaces are provided on the trigger, where such actuators or actuators can be arranged.

Further embodiments and variations of the present invention will become apparent to those skilled in the scope of the claims.
