Abstract

The invention relates to a device for preventing the tensioning of a firing pin spring when disarming a hammerless automatic pistol (1) provided with a lock slide (7), wherein the device can assume a disarming position and a locking position, comprising: a spring-loadable firing pin (17) with a lug (17a) formed thereupon for operative engagement with a catch (19), which in the tensioning position for tensioning the firing pin spring protrudes into the path of movement of the lug (17a) and in the disarming position is operatively disengaged from the lug (17a), a sear bar (27), which is coupled with a trigger and operatively disengages the catch (19) from the lug (17a) in the disarming position; and is characterized by a disarming shaft (15), which in the disarming position allows a forward movement of the trigger, and consequently of the sear bar (27), and a disconnector bar (21), which can be coupled with the sear bar (27) and in the disarming position is acted upon by the forwardly moved lock slide (7), and thereby operatively disengages the catch (19) from the lug (17a) by means of the sear bar (27). The invention also relates to an automatic pistol provided with such a device.

Description

Device for preventing the tensioning of a firing pin spring during disassembly of a tapeless self-loading pistol provided with a closing slide and

Self-loading pistol with such a device

The invention relates to a Schlagbolzenfederspannverhinderungsvorrichtung, more precisely a device for preventing the tensioning of a firing pin spring in the

Disassembly of a tapeless self-loading pistol with a slide. Such a device can assume a locking position or clamping position and a disassembly position and has; a spring-loaded firing pin with a projection formed thereon for operative engagement with a sear which protrudes into the clamping position for tensioning the firing pin spring in the path of movement of the approach and in the disassembly position is out of operative engagement with the approach, and coupled with a trigger trigger bar, the in the disassembly position brings the sling pawl out of operative engagement with the approach.

The invention also relates to a self-loading pistol equipped with such a device. In these documents, position designations such as "top", "bottom", "front", "rear", etc. always refer to the view of a shooter who keeps the self-loading pistol in normal firing position with horizontal axis of the soul.

State of the art

Self-loading pistols with a device for preventing the tension of the

Striker pin spring during disassembly of these pistols are in different

Executions known. Such a device serves an unintentional Firing during disassembly of the self-loading pistol, for example, for the purpose of their cleaning or checking their technical condition to prevent. It is also known to relax the trigger system via an additional keypad, such as a release lever, or simply by being triggered by actuation of the trigger.

Furthermore, tapeless self-loading pistols - also called pistols with firing pin lock - are known. When loading these guns, the shutter slide is released from its rear position and the closing spring drives the shutter slide forward. The firing pin is caught by a Fanklinke - also called trigger lever - in the handle and therefore can not slide with the shutter slide forward. The leading shutter slide compresses the one in it

Firing pin spring. If the shooter then actuates the trigger mechanism in the handle, this releases the preloaded firing pin. On the other hand, in the case of a tension release system, the trigger pull can, in addition to the firing pin release function, fully or partially tension the firing pin spring.

To disassemble such a tapeless self-loading pistol usually holds a shooter with one hand, the gun on the handle body of the handle and engages with the other hand, the closing slide or the closure top from above. Then he pulls the slide to the rear, against the spring force in the handle

arranged closing spring until a catch catch catching the shutter slide in its Verschlussfangstellung, i. holds. A cartridge which may be present in the cartridge chamber is ejected when the closing slide is withdrawn. In the catching position of the closing slide can be a disassembly lever or a

Turn the dismounting shaft via an external handle from its locking position into its disassembly position. The dismantling shaft blocked in her

Locking position an approach at the bottom of the tube, so that the tube can not be removed. In the disassembly position, this approach can over the

Slide the disassembly shaft away and disassemble the gun in the usual way. To

Release of the closing slide by pressing the closing catch lever, the closing slide can then be removed forwards together with the tube and the closing spring. If tapeless guns are dismantled without appropriate safety devices with loaded magazine loaded, a cartridge from the magazine is fed to the chamber and the firing pin spring tensioned. When retiring the

Sliding slipper slides this over the magazine and releases space above the magazine. A magazine spring then forces a cartridge from the magazine up into the path of movement of the closing slide. During the advance or guided forward sliding of the closing slide from its catching position, this engages, driven by the spring force of the closing spring, with its underside against the cartridge, more precisely at its cartridge bottom, and pushes the cartridge forward into the chamber. Unless there is a device for preventing the tensioning of the firing pin spring from disassembling, catching and holding a firing pawl during the advance of the closing carriage. The further sliding slide then tensions the

Firing pin spring. Unlocks the user to remove the carriage forward the sear by pressing the trigger and triggering the firing pin, so in such cases unintentionally triggered during disassembly shot.

EP 1 022 535 A2 discloses a tapeless self-loading pistol with a

Trigger mechanism in which in a clamping position, a catching member protrudes into the path of movement of a firing pin (called firing pin there) formed Fangnase. The

Catch member is provided at the top of a in the rear part of the handle

Use trained. The insert comprises a spring-loaded pawl, which is guided over pins in obliquely downwardly extending oblong holes.

When loading the catch nose acts upon a movement of the closing slide to the rear of the catch member, while pushing the pawl against the force of a spring backwards down until the catch nose can slide over the catch member away. During the subsequent forward movement of the closing slide due to the relaxing

Closing spring from its rear position, captures and holds the catch member the catch nose, the further leading shutter slide biases the firing pin spring. The pistol is ready to fire.

In trigger operation, a trigger rail acts on the pawl and pushes it back down until the catch member is disengaged from the catch nose and the Firing pin releases so that a shot is fired. When followed

Sliding back of the closing slide pivots the pawl back into its clamping position. For disassembly of the gun, a control lever is provided, the outer handle is rotatable with the shutter open in a Zerlestellungung. In this case, a pin is lowered in one of the slots in the pawl, so that the pawl and the catch member get out of the movement path of the catch nose. After pulling a bolt by means of a disassembling lever, the shutter slide can be pulled off to the front.

EP 2 294 352 A2 discloses a further mechanism for disassembling a

Handgun without tensioning the firing pin spring. In a clamping position of the mechanism, the trigger rod protrudes into the path of movement of a neck on

Firing pin and catch and hold it. For disassembly, an eccentrically mounted disassembling lever and a horizontally movable trigger rod catch lever for actuating a spring-loaded trigger rod catch member are provided. When turning the Zerlegehebels this moves the trigger rod catch lever backwards and thereby twisted the trigger rod catch so that it does not catch the trigger bar nor the firing pin, but is held on the firing pin from the path of movement of the approach. Now the slide can be pulled off the handle to the front, without the firing pin spring is tensioned.

Task and solution of the invention

Object of the present invention is to provide another device for preventing the tension of the firing pin spring when disassembling a self-loading pistol and a self-loading pistol equipped with it. This object is achieved by the subject-matter of independent claims 1 and 13, respectively. The generic device according to claim 1 thus additionally comprises the following features: a disassembly shaft which allows in the disassembly position a movement of the trigger and thus the trigger bar forward, and engageable with the trigger rod interrupter rod which acts in the disassembly position of the forwardly moving shutter slide and thereby the sling by means of

Trigger rod out of operative engagement with the approach brings.

The generic self-loading pistol of claim 13 is characterized in that it is provided with a device according to one of claims 1 to 12.

A disassembly of a gun according to the invention is therefore only possible if the disassembly shaft is in its disassembly position, so that the sear reaches the firing pin from the range of motion of the approach. Thus, the device ensures a safe disassembly, since in their disassembly position the

Striker spring is not tensioned and therefore no shot can solve.

In addition, disassembly is only possible if the user releases the mechanism of action of the device deliberately in several successive steps, namely: 1. removal of the magazine, 2. retraction of the closure and manual engagement of the shutter lever, 3. twisting the disassembly shaft for disassembly, 4 Holding the shutter and releasing the shutter catch lever, 5. Guided removal of the shutter with pipe and closing spring forward, so that unintentional disassembly is prevented. Incidentally, the pistol is mounted in reverse order

Steps. The device is due to the relatively simple and robust technology with pollution-insensitive translational or vertically moving components less prone to failure. This even with strong mechanical loads from the outside, so that the reliability and reliability of the self-loading pistol is given. Preferably, a stop is provided in the device on the trigger and the

Dismantling shaft has a, preferably wedge-shaped recess or a portion of reduced diameter on which in the disassembly position with twisted disassembly shaft of the stop of the trigger spring-loaded (claim 2). The spring-loaded abutment abutment at the reduced diameter portion of the disassembly shaft is permanent, the reduced diameter forming a continuous slip bevel which falls in the disassembly direction of the shaft and rises in the locking direction of the shaft so that the trigger and trigger stem are in the disassembly direction move the shaft forwards and backwards in the locking direction of the shaft.

Preferably, the disassembly shaft prevents in its locking position movement of the stop and thus the trigger and the trigger bar forward (claim 3).

The dismantling shaft comprises in a simple production engineering embodiment, a region of larger diameter, which is opposite to the stop when rotated in its locking position disassembly shaft and thus blocks its forward movement. Thus, the disassembly shaft ensures in its locking position a tensioning of the firing pin spring of the self-loading pistol, since the squeezing pawl is located in the range of motion of the approach to the firing pin.

Preferably, the forward movement of the trigger rod allows their force engagement with the interrupter rod and the sear (claim 4).

For this purpose, the trigger bar may be provided with at least one active element, which comes into operative engagement with the disconnecting rod. The trigger bar can be provided for the force engagement, for example, with a projection, pin or other shape with appropriate geometry.

Preferably, the trigger bar is provided for the force engagement with at least one tab (claim 5).

A tab can be manufacturing technology with simple means, about a reshape a part of the trigger bar, provide. In a parallel arrangement of the trigger bar and the interrupter rod, the tab, the interrupter rod under attack. Also, a second tab can be designed for an operative engagement with the sear. The Applicant reserves the right to claim independent protection for such a trigger bar. Preferably, the sear has a projection for the force engagement with the trigger bar (claim 6).

The projection can be arranged, for example as a pin, pin or bolt on the sear, for example, be inserted therein, or be provided as another shape with suitable geometry. The trigger bar can comprise a second active element, for example a second tab, which can be brought into operative engagement with the projection. The protruding components interact in terms of movement in a simple manner.

Preferably, the interrupter rod for the force engagement with the trigger bar in a recess comprises a step (claim 7).

The recess and the step can be produced by simple means, such as punching, milling or other suitable. The tab of the trigger bar engages in the recess.

Preferably, the interrupter rod on its side facing the closing slide a survey and is acted upon by a lower contour of the moving closing slide acted upon (claim 8). This measure provides with mechanically simple means an effective control curve, which allows their actuation only with active engagement of the survey with the underside of the closing slide.

Preferably, the closure slide comprises on its underside a first recess, which can be brought into closed engagement with the elevation of the interrupter rod in an operative engagement (claim 9). Preferably, the closure slide comprises on its underside at least one second recess, which can be brought into operative engagement with the elevation of the interrupter rod in its closure catch position (claim 10).

The first and the second recess each prevent loading of the interrupter rod when the collection of the interrupter rod is immersed in one of the recesses.

Preferably, a non-recessed area on the underside of the closure slide pushes the interrupter rod downwards during its forward movement out of its closure catch position, which thereby comes into positive and / or force engagement with the trigger bar, brings it into form and / or force engagement with the sear and the Trigger rod brings the sear from the trajectory of the firing pin (claim 1 1).

Preferably, the device comprises a release latch, which is coupled to the trigger rod upon actuation of the trigger and so brings the sling to disengage the shot out of engagement with the approach (claim 12). This measure ensures a firing in the tensioning position.

Figures 1 to 4 show the functional sequence of disassembly of a tapeless

Self-loading pistol 1 and Figures 5 to 8, the individual elements of the gun 1 before, during and after firing. The construction and operation of the device for preventing the striker spring from being disassembled when the gun 1 is disassembled will be explained with reference to FIGS. 9 to 17.

Figure 1 shows an external view of a self-loading pistol 1 in the assembled state but with removed magazine 3. The self-loading pistol 1 comprises a handle 2 and a tubular 9 surrounding slide 7. About a trigger 5 can be shown in Figures 5 to 17 trigger mechanism in operate known manner. By means of an external handle 15a can be a not visible here, in Figs. 9 to 17 shown, arranged in the handle 2 disassembly shaft 15 rotate in a locking position or in a disassembly position.

The handle 15a has, in the locking position, also called clamping position, horizontal to the rear. It blocks u. a. a projection 12 on the underside of the tube 9 (see Fig. 4), and thus prevents removal of the tube 9. In the

Disassembly position shows the handle 15a down (see Fig. 3 and 4). In this position, the tube 9 and the shutter slide 7 and the

Closing spring assembly 39 after releasing a known locking catch 10 forward from the handle 2, since the projection 12 can slide over the disassembly shaft 15 away. Such a dismantling shaft is described, for example, in DE 10 2013 010 969.8 of the applicant of the same name, which is hereby expressly incorporated by reference. The catch lever 10 catches and holds in a known manner the closure 7 in its closed position (see Fig. 2). At the bottom of the shutter carriage a half-round recess 6 is provided, which is positioned so that it is only in the locked position, a rotation of the disassembly shaft 15 in their clamping or

Disassembly allows - and this only if previously the magazine 3 was removed.

FIG. 2 shows the self-loading pistol 1 with withdrawn closing carriages 7 in the open locking position held by the locking catch 10. When retracting the shutter slide 7 in its closed position is a possibly in

Cartridge bearing cartridge ejected. The disassembly shaft 15 is in its locking position.

In the illustration in Figure 3, the disassembly shaft 15 is rotated by means of the now downwardly facing handle 15a in a clockwise direction in its disassembly position. This is only possible in the closed position in which the disassembly shaft 15 is located in the semicircular recess 6 on the bottom side of the shutter carriage; also only with removed magazine, so an empty magazine shaft. Figure 5 shows the gun 1 with cocked striker before its release and

Teeing. As is known, the following items are provided for firing: the trigger 5, the trigger 5e, a trigger 5 coupled to the trigger rod 27, a release latch 45 (see FIGS. 6 and 7), a sear 19, the firing pin 17 with a lug 17a and the Sliding carriage 7. The structure of these components and their

Cooperation will be described below.

The trigger 5 is pivotally mounted about a take-off shaft 5 a and from a

Leg spring 5b (see Fig. 7) and a spring 37 (see Fig. 1 1) biased in its rest position shown in Figure 5. The trigger 5 comprises on its rear side a shoulder 5c (cf., in particular, FIG. 9). This approach 5c serves as a cover to complicate the ingress of dirt and debris on the exhaust port in the handle.

The trigger bar 27 is at its front end over a

Trigger rod bearing axis acting, the trigger 5 transverse to the firing direction

passing through pin 5d coupled to the trigger 5 in terms of movement and mounted pivotably about the pin 5d. The trigger bar 27 is coupled in a known manner to its support in the handle 2 on its underside approximately centrally with a doubly curved (approximately earthworm-like curved) spring 37 (see Fig. 6 and 7). The trigger rod support in the handle 2 is shown schematically in Figures 9, 12 and 14. This spring 37 allows a vertical and translational movement of the trigger bar 27 and a movement of the trigger 5 in its rest position. At its rear end, the trigger bar 27 comprises a lower flap 29 formed to the right side and an upper flap 31 formed to the left side at its upper end. The functions of the flaps 29 and 31 will be explained later.

The trigger also includes a securing tongue 5e, which protects in a known manner the trigger at case or shock accelerations against unwanted trigger triggering. This fuse 5e is also in the trigger on the

Abziehsstangenlagerachse 5d stored and is automatically upon actuation of the trigger to this axis and against a spring, not shown, located in the trigger

pivoted, whereby the trigger against the handle is unlocked and the withdrawal shaft (5 a) can be pivoted. The release pawl 45 shown in Figures 6 and 7 is provided on the left side, at the rear end of the trigger bar 27. The trigger pawl 45 is a transversely to the

Shot direction passing through, used in the handle 2 Auslösekliniklagerungsachse 49 pivotally mounted. The use of the tripping bearing axis 49 in additional wall elements of the handle 2 is known and not shown. The

Release latch 45 is at its rear, lower end tab-shaped for engagement with the sear 19 to the left bent (see the following paragraph) and comprises at its rear upper end in the weft direction, the upper tab 31 of the trigger bar 27 projecting nose 47th

The sear 19 is in the region of the rear end of the trigger bar 27 and parallel to this, left side of the upper nose 47 of the release latch 45 below the

Striker provided 17 and pivotable about a bearing axis 19b in

Grip 2 stored. At the rear end of the sear 19 protrudes approximately centrally a nose 19d backwards. Below the nose 19d includes an approximately rectangular formed

Recess, which is bounded below by a hook-like end 19e of the sear 19 (see Fig. 5). In this recess, the release latch 45 engages with its lower tab-shaped end (see Fig. 6 and 7). A compression spring, which is provided approximately centrally on the underside of the sear pawl 19 and acts as a return spring 19c (cf., FIGS. 8 to 17), supports the sear catch 19 downward in the grip piece 2. The support in the

Handle 2 is shown schematically in FIGS. 9, 12 and 14. At the front end of the sear 19 is provided in the direction of the trigger bar 27 transversely to the axis of the gun 1 extending pin 19a. At the top of the sear 19, a step 19f is attached.

The firing pin 17 is longitudinally movably mounted in a firing pin guide 18 and comprises at its front end a firing pin 17c. From his

Striker tip 17c he thickened in approximately cone-shaped backwards to serving as a firing pin spring bearing annular shoulder 17d, in turn to a

Section 17b connects with a smaller diameter. A firing pin spring 17e surrounds the firing pin 17, which is provided with its front end on the shoulder 17d and with its rear end to a provided in the firing pin guide 18, the

Striker 17 surrounding firing pin guide sleeve 18a is supported. The Firing pin guide sleeve 18a leads the rear end of the firing pin 17th Die

Impact bolt guide sleeve 18a has on its underside extending over about 4/5 of the length of the sleeve longitudinal slot 18b, in which the projection 17a of the firing pin is guided.

At its rear end, the firing pin guide 18 is supported on the terminating and supporting piece 58, in the inner contour of which it is spring-loaded and thus the closing and supporting piece 58 mounted vertically in the direction of the firing direction in the rear part of the closing carriage, as in other pistols, is slidably mounted in a slot Way locked.

Further, at the rear end of the firing pin 17 a downwardly projecting, the

Firing pin guide sleeve 18a in the longitudinal slot 18b enforcing approach provided 17a. Within the firing pin guide sleeve 18 a is a

Firing pin return spring 17f arranged: This firing pin restoring spring is supported with its rear end on the firing pin 17 and with its front end on the firing pin guide sleeve 18a and pulls at knocked off, at rest striker 17 this backwards. As already described, the squeezing pawl 19 projects in its clamping position with its rear upper end in the path of movement of the projection 17a and begins when loading the gun 1 with the closing slide 7 leading striker 17 on the approach 17a. In the clamping position shown in Figure 5, the lug 17a is located with its lower front edge in the step 19f of the sear 19 and is held by this. The further advanced shutter slide 7 has the firing pin spring 17e clamped in a known manner against the firing pin spring bearing 17d, since the

Closing slide 7 takes the firing pin guide sleeve 18a on further forward so that the front end of the firing pin spring 17 compresses. The trigger mechanism is ready to fire in this mutual operative connection.

Figures 6 and 7 show the cocked firing pin 17 at the moment of its release by the sear 19. The trigger 5 is against the spring force of the leg spring 5b and the spring 37 is actuated to the rear. The pin 5d has the trigger bar 27 coupled thereto taken behind, with the front end of the trigger bar has moved on a circular path around the trigger shaft 5 a back to the top. The rear end of the trigger bar 27 is displaced in the longitudinal direction to the rear lower compared to Figure 5, wherein the lower flap 29 of the trigger bar 27 from a recess 24 in a

Breaker rod 21 is led out to the rear and so the rear end of the

Trigger bar 27 moves down. The upper tab 31 of the trigger bar 27th

acts on it with its rear end face, the nose 47 of the release latch 45, so that it is pivoted on a circular path about its bearing axis 49 to the rear bottom. The trigger pawl 45 has pivoted over its operative engagement the Fanklinke 19 against the spring force of the return spring 19c (see Fig .. 9 ff.) About the bearing axis 19b backwards down. The lug 17a is thereby disengaged from the step 19f of the sear 19 and can now freely run forward for firing. At the end of its trajectory strikes the firing pin 17 with its tip 17 c on a cartridge bottom not shown, not shown, provided in the cartridge chamber 51 cartridge and ignites a propellant charge in a known manner.

Fig. 8 shows the gun 1 with knocked-off firing pin and empty cartridge chamber. The firing pin spring 17e is relaxed and the firing pin 17 is in its forward position, slightly spaced from the cartridge chamber 51. Since the firing pin spring 17e is supported on the shoulder 17d, it does not urge the firing pin 17 completely and permanently onto a primer of the cartridge, not shown, in the cartridge chamber 51. Rather, when firing, the firing pin 17, due to its inertia, runs beyond the position shown in FIG Compresses its return spring 17f in the firing pin guide sleeve 18a. After the flow and empty cartridge chamber, the return spring 17f the firing pin 17 slightly back until the

Impact bolt head 17g resting on firing pin spring bearing (17d).

The trigger 5 is pivoted in Figure 8 back to its rest position. The pin 5d has the trigger rod coupled thereto 27 taken to the front, with the front end of the trigger bar has moved on its orbit around the trigger shaft 5a forward and downward. The rear end of the trigger bar 27 is again in its initial position shown in FIG. 5, as well as the sear 19 and the release latch 45, not shown in Fig. 8. In order to tension the firing pin 17 and its spring 17e, the closing slide 7 must be retracted until the catching pawl 19 underlies the projection 17a. After that, the shutter carriage must be released again. The structure and operation of the device for preventing the striker spring from being dislocated during disassembly of the self-loading gun 1 will now be described with reference to FIGS. 9 to 17. Since the firing pin spring 17e is not tensioned during disassembly, no shot can unintentionally solve this. The device for preventing a tensioning of the firing pin spring according to FIGS. 9 to 17 comprises the following interacting components: the trigger 5, the dismounting shaft 15, the trigger rod 27 coupled to the trigger 5, the

Breaker rod 21, the sear 19, the firing pin 17 with his approach 17a and the shutter slide 7. The interaction of these components during disassembly will be described below.

Figures 9 to 1 1 show a part of the trigger mechanism in its clamping position with closed shutter carriage 7 and located in its clamping position firing pin 17. The shutter slide 7 shown in Fig. 9 (schematically) is in its forward position, in which he front end almost flush with the tube 9 closes (see also Fig. 1). The handle 15a of the dismounting shaft 15 has in its locking position horizontally to the rear (see also Fig. 10) and prevents as described above disassembly of the gun 1. The trigger 5 comprises at its upper end a trained as a neck, projecting forward stop 35th , Which here of the deduction in its rest position biasing leg spring 5b and the spring 37 spring-loaded on the inner circumference of the disassembly shaft 15 is applied. The disassembly shaft 15 prevents here a translational forward movement of the

Stop 35 and thus a forward movement of the trigger 5 and the associated trigger rod 27. Figures 10 and 1 1 show this state in each case in a view obliquely from the top right or left side of the gun 1 from - but without Representation of the closing slide 7. At the rear of the inner part of the

Disassembly shaft 15 is a, preferably wedge-shaped recess 23 is provided, which is opposite to the stop 35 only in disassembly position, ie only if the

Disassembly shaft 15 is rotated in this position, and so room for a

Forward movement of the stop 35 (see Fig. 10 to 13).

The interrupter rod 21 is at its front end to the take-off shaft 5a

pivotally mounted and comprises at its rear end an approximately semicircular, trough-shaped recess 24 which has in its front region a rising from the bottom of the tub level 25. At the the shutter slide 7 facing

Top of the interrupter rod 21 is an approximately trapezoidal elevation 33 is formed. This is for engagement with each one approximately complementary first, front recess 8 or second, rear recess 8a, provided in the closure slide 7. In the closed slide carriage position shown here, the elevation 33 is in engagement with the rear recess 8 a. When moving the

Closing slide 7 to the rear this slides with its non-recessed area 8b on the elevation 33, this applied downward and thereby pivots the interrupter rod 21 down until the elevation 33 in the closed position engages with the front recess 8 (see FIG. 12).

The trigger bar 27 engages in the relaxed position shown in Fig. 9 to 13 with its lower flap 29 approximately centrally the recess 24 of the interrupter rod 21 and is spaced from the step 25. The upper flap 31 protrudes laterally in the direction of the sear 19, which is arranged at the rear in addition to the trigger bar 27. The pin 19a of the sear 19 is offset to the tab 31 slightly forward, so that these two elements do not engage with each other in the cocking position of the trigger bar.

In Figure 12, the shutter slide 7 is retracted to its closed position. Starting from FIG. 9, when the closing slide 7 is pulled back, the approximately trapezoidal rear slide recess 8a slides over its front run-on slope-below the obliquely rearward-directed force influence-over the elevation 33 of FIG

Interrupter rod 21. The non-recessed portion 8b of the shutter slide 7 then acts on the interrupter rod 21 while retracting the Closing slide 7 down until the elevation 33 with the front

Carriage recess 8 comes into engagement. The rear recess 8a, which was still in engagement with the elevation 33 of the interrupter rod 21 in FIG. 9, is free. When pulled back, the closing slide 7 takes the firing pin 17 arranged therein back so that its projection 17a is disengaged from the catch 19. The firing pin spring 17 is relaxed in this state.

Releases the trigger bar 27, the sear 19 as shown in Fig. 6 and 7, and ignites the firing pin 17 located in a cartridge chamber cartridge, then the return of the carriage 7 on the non-recessed area 8b of the carriage the

Interrupter rod 21 controlled by its elevation 33 down and takes over the voltage applied to the interrupter rod 21 lower tab (29) of the trigger bar 27 the

Trigger bar with down. As a result, the upper flap 31 of the trigger rod 27 slides down into the groove 45a of the trigger pawl 45, whereupon the trigger pawl 45 and the sear 19 are returned by the return spring 19c back to its original position and catch position and the firing pin can be caught again. If the trigger is released after the shot, then the lower tab 29 of the trigger rod 27 slides back into the recess 24 of the interrupter rod 21. The spring 37 pushes the trigger rod 27 upwards into its initial position (see Fig. 5), whereby the upper tab 31 of the trigger rod again in front of the nose 47 of the release latch 45 comes to rest and the cocked firing pin 17 can be triggered by pressing the trigger on the upper tab 31 of the trigger rod 27 and the nose 47 of the trigger 45. The interrupter rod 21 is, as the name implies, thus also as

Breaker element for semi-automatic closing.

The disassembly shaft 15 is in Fig. 12 still in their

Locking position, so that the stop 35 of the trigger 5 continues to bias under tension of the trigger leg spring 5b and the spring 37 abuts the disassembly shaft 15. Figure 13 shows this state in a view obliquely from the top front. In Figs. 14 and 15, the disassembling position of the device for preventing the tension of the striker spring at disassembly is shown. In contrast to FIGS. 12 and 13, the outer handle 15a and thus the disassembly shaft 15 is rotated by approximately 90 ° in the clockwise direction downwards. After rotation, the recess 23 is located with its edge 23 a of the disassembly shaft 15 against the spring-loaded stop 35. This pivots with the trigger 5 under the force of the trigger leg spring 5b and the spring 37 counterclockwise on a circular path around the trigger shaft 5a until it abuts the upper edge 23a of the recess 23. The starting position of the trigger 5 is shown in dashed lines in Figure 14. During its pivoting movement of the trigger 5 also takes the coupled with him trigger bar 27 forward in the position shown in Figures 14 and 15 with. This has the consequence that the lower flap 29 of the trigger bar 27 come to rest under the step 25 of the interrupter rod 21 and the upper flap 31 of the trigger bar 27 on the pin 19a of the sear 19. The closing slide is still in its rear closing position.

Figures 16 and 17 further show the device for preventing the tension of the firing pin spring disassembled in its disassembly position and the user for disassembly of the self-loading pistol 1 partially guided to the front closure carriage 7. Starting from Figure 14 slides the trapezoidal front recess 8 at

Forward movement of the closing slide 7 via its left rear run-on slope 8b under the forwardly directed force influence over the elevation 33 of the

Interrupter rod 21. The lower contour of the non-recessed portion 8b of the closing slide 7 acts on the elevation 33 and thus the interrupter rod 21 upon further forward movement of the closing slide 7 down. Because the

Trigger rod 27 with its lower tab 29 at the bottom of the stage 25 of the interrupter rod

21 is applied, the trigger bar via the interrupter rod 21 is also controlled down and brings it in the locked course in the unlocked position

Disassembly shaft 15 with its upper tab 31, the sear 13 over its pin 19a out of engagement with the also vorgleitenden approach 17a of the firing pin, so that the firing pin is neither caught nor tensioned. In the closed position of the

Closure slide 7 is the elevation 33 in the rear recess 8 a and is not acted upon. When pulling the shutter slide 7 forward, the non-recessed area 8 c applied to the elevation 33. During their admission by the non-recessed area 8b or 8c urges the interrupter rod 21 in the disassembly position form-fitting their stage 25 on the tab 29 and thus the

Trigger bar 27 down. This arrives with its upper tab 31 in

Form engagement with the pin 19a of the sear 19 and moves them as done in the recess 8 and the non-recessed area 8b, against the force of the return spring 19c down from the path of movement of the projection 17a on

Striker 17, wherein the lug 17a on the firing pin 17 in this position of the

Closing slide 7 can not be caught by the sear 19. In the locked position, however, blocks the dismantling shaft 15, the trigger bar 27 in its rear position, so that when the trigger 5 is not actuated, the lower flap 29 laterally offset to the step 25 approximately centrally located in the recess 24 of the interrupter rod 21 (see Fig .. 9 bis 13). In this position, the breaker bar 21, the tab 29 is not applied, since the depth of the recess 24 corresponds approximately to the height of the elevation 33, so that a positive connection of these elements is not possible. The upper tab 31 of the trigger bar 27 is offset in the clamping position in the longitudinal direction of the pin 19a (see Fig .. 9 to 13) and therefore can not act on him.

In the disassembly position of the individual elements shown in Figures 16 and 17, a safe withdrawal of the closing slide 7 forward is possible because the

Squeezing pawl 19 no longer catch the firing pin 17 at its base 17a and therefore can not tension the firing pin spring 17e either.

In principle, it is possible to replace the recesses 8, 8a of the closure slide 7 and the elevation 33 of the interrupter rod 21 by other geometric shapes and thereby also allow an effective power transmission.

The stage 25 of the interrupter rod 21 and the pin on the sear 19 or the tabs 29, 31 on the trigger bar 27 are just as well without limitation

Mode of operation of the device by other functionally comparable elements replaceable.
