EP3087339B1 - Hammerless self-loading pistol safety system which prevents accidental discharge if dropped, and self-loading pistol with such a safety system - Google Patents

Description

The invention relates to a fall arrest of a tapeless self-loading pistol with a movable securing element, which can take a securing position in which it engages in the trajectory of a firing pin before firing shot, and a release position in which it is outside the trajectory of the firing pin.

The invention also relates to a self-loading pistol equipped with such a fall arrester.

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

Hahneless self-loading pistols - also called pistols with firing pin lock - are known in various designs. When loading these guns, the shutter slide is released from its rear position and the closing spring drives the shutter slide forward. When tapeless self-loading gun without jaw system while the striker is arranged in the closing slide of a sling - also called trigger lever - caught in the handle and therefore can not slide with the shutter slide forward. The leading shutter slide compresses the firing pin spring in it surrounding the firing pin and thereby tension the firing pin. If the shooter then actuates the trigger mechanism in the handle, the latter releases the prestressed firing pin. In the case of tapeless self-loading guns with a clamping trigger system, however, the operation of the trigger mechanism in addition to the firing pin release function, the firing pin spring also still quite or partially tension.

Even safeties for self-loading pistols are known in different versions. Fall arrest serves to prevent inadvertent firing upon dropping or other stress on the self-loading gun.

US 2011/0289811 A1 For example, shows a tapeless self-loading pistol with a fall arrester. In its securing position is a two-armed safety lever with a first lever arm on a standing with the firing pin engaged safety slide and holds with its second lever arm the preloaded firing pin.

The safety lever is coupled to the trigger via the trigger rod. Upon actuation of the trigger to the rear this moves the trigger rod backwards, which in turn pivots the safety lever, so that the first lever arm moves the safety slide up to its release position. The safety slide comprises a complementary to the outer dimension of the firing pin recess, so that in the release position of the firing pin can slide past the safety slide.

EP 1 281 924 B1 shows a firing pin safety device of a self-loading pistol with cock ignition with a rotating and sliding safety slide. In the safety position, the safety slide represents the firing pin. Upon actuation of the trigger this first acts on a safety lever, which in turn acts on the safety slide, and this rotated by a 90 ° angle to the firing pin axis of rotation so far that the "rotary" safety slide unlocked radially from the firing pin on another trigger actuation of the safety lever moves the Locking slide axially upward from a groove on the firing pin in its release position and unlocks the firing pin.

US 7,703,230 B2 discloses a firing pin safety device of a tapeless self-loading pistol. The firing pin safety device comprises a securing element, which is arranged vertically laterally on the firing pin and retains this together with the trigger lever in the securing position in its cocked position. For this purpose, the firing pin comprises lateral projecting contact surfaces on which the securing element engages. Upon actuation of the trigger, the trigger bar pivots a lever arm, which in turn acts on the fuse element and this moves axially upward. In this case, the securing element comes out of engagement with the contact surfaces and releases the firing pin in the release position.

US Pat. No. 7,810,268 B1 discloses a tapeless gun with a trigger bar coupled to the trigger. At the rear end of the trigger bar an extended arm is provided which captures the striker on an extension on its underside, tensioned and held in its cocked position. For firing the trigger is actuated, which in turn pivots the trigger bar and the rear extension of the path of the firing pin and so releases. In addition, an ejector is provided, which is coupled via a sliding connector with the trigger bar. The fitting prevents the trigger bar from moving downward when the trigger is not actuated, thereby slipping the extended arm of the trigger bar away from the extension of the firing pin, thereby preventing shot firing in the event of unintentional dropping of the gun.

US 5,157,209 A , which forms the starting point of the present invention discloses a tapeless self-loading pistol with a firing pin safety and a vertically slidable in the carriage fuse element. In its securing position, the securing element engages with its upper side in a recess on the firing pin in engagement and prevents it from further forward. Upon actuation of the trigger, a trigger provided on the trigger acts on the securing element and displaces it upward in its release position, so that a firing is possible.

Task and solution of the invention

The object of the present invention is to provide an improved and functionally reliable fall protection of a self-loading pistol and a self-loading pistol equipped with this fall arrester.

This object is achieved by the subject-matter of independent claims 1 and 11, respectively.

In accordance with claim 1, the generic fall protection is therefore characterized in that the securing element in the securing position the firing pin only after its flow over a defined distance. The defined distance is of course shorter than the distance required for firing shot, but such that the firing pin spring is fully or almost completely relaxed and therefore the energy of the previously strained firing pin spring is completely or almost completely consumed in the trapped positions. Therefore, the firing pin spring can no longer drive the firing pin to fire a shot, even if a shooter in this relaxed position of the firing pin should release the trigger and press again.

Furthermore, the claimed fall protection is characterized in that the securing element of the fall arrest between its securing position and its release position is arranged horizontally rotatable or pivotable and formed. The fall protection also includes a particular pin-like storage element which is rotatably mounted with a first end in a recess in the closure slide. In this case, a two-armed locking lever is provided at a second end of the bearing element of the fall arrester, which projects in its securing position with a free end of the fuse to a first lever arm for catching the firing pin in its trajectory.

The generic self-loading pistol of claim 11 is characterized in that it is provided with a fall arrester according to one of claims 1 to 10.

A firing of a self-loading gun according to the invention is only possible if the fall arrest is in its release position, so that the securing element passes out of the range of motion of the firing pin. Thus, the fall arrest prevents accidental firing if the self-loading pistol is dropped or otherwise shaken. In the backup position, although the striker spring may be partially relaxed with any unintentionally deployed firing pin, but because the fuse captures the firing pin and contacts the primer of a cartridge located in the chamber prevented, no shot can solve.

The device is due to the relatively simple and robust technology with pollution-prone components less prone to failure. This even with strong mechanical loads from the outside, so that the self-loading pistol is therefore also more reliable and reliable than known tapeless self-loading pistols.

Characterized in that the invention provides that the firing pin travels a defined distance in case of unintentional release, and is then collected, the present invention of the known principle to hold a cocked firing pin on a securing element in the tensioned state and secure, from. In comparison to known drop locks, which are based on a linearly guided and unilaterally force-loaded pressure pin, which engages in the firing pin, cf. such as the aforementioned US 7,703,230 B2 Advantageously, the present invention prevents the fall arrester, for example, due to soiling from unintentionally remaining in the release position, thus allowing an accidental ignition of a cartridge in the event of a fall.

A rotating about an axis rotation lock can be made neutral to the mass with respect to a spring-loaded sliding safety and is as safe as possible together with the force acting on them spring force.

A rotatable mounting of the bearing element allows a rolling movement of the fall arrest on the firing pin guide sleeve during pivoting. The storage element may, for example, as a pin, bolt or other suitable axle be formed, which is then inserted via a plug-in connection in a recess in the closure slide. The recess can be provided, for example, by simple means as a bore in the shutter slide.

The two arms of the safety lever, for example, can be perfectly balanced with respect to one another and designed to be largely mass-balanced to one another. This measure counteracts mass acceleration, as occurs in case of collision or shock.

Preferably, in the fall protection, the securing element in its securing position, the firing pin only shortly before a shot firing on (claim 2).

This measure allows the longest possible distance of the firing pin.

Preferably, in the case of securing the securing element is movably mounted on a firing pin guide sleeve surrounding the firing pin (claim 3).

The storage of the securing element on the firing pin guide sleeve can be accomplished with manufacturing technology simple means. In addition, this arrangement allows a compact and space-saving design of fall protection.

Preferably, in the fall arrester, an elastic element biases the securing element in its securing position (claim 4).

The elastic element can be provided, for example, as an elastomer or a correspondingly suitable spring element, for example a leaf or leg spring. The bias of the fuse element in its backup position increases the safety of the fall arrest and prevents inadvertent firing.

Preferably, in the case of securing the fuse element in one piece or in several parts (claim 5).

A one-piece design ensures a high stability of the fall arrester. Alternatively, however, it is also possible to provide a fall arrester comprising a plurality of components, which are correspondingly coupled to one another via suitable fastening means or, for example, via plug-in, latching or other connections. The latter allows the replacement of individual components of fall protection.

Preferably, the fall arrestor at the free end of a second lever arm of the safety lever on a control for an operative engagement with at least one control contour of a trigger rod coupled to the trigger on (claim 6).

The control may be provided, for example, as a projection, pins, bolts or other formations of suitable geometry. The control contour on the trigger bar can be provided with correspondingly suitable geometries, for example as a tab, projection or other suitable design. In a simple embodiment, the control contour is provided as a survey. A projecting component interacts with the control contour in a simple manner in terms of movement.

Preferably, in the fall arrest in the rest position of the trigger the trigger bar with at least a first control contour behind the control in its securing position and thereby prevents movement of the fuse element in its release position (claim 7).

Due to this positive background, the securing element can not rotate out of the securing position with a relaxed trigger, which ensures a high level of security of the fall arrester.

During the backward movement of the closure, the trigger bar tilts out of engagement with the anti-rotation device.

In particular, with any contamination of the fuse element or the fall arrest ensures the at least one control contour a return of the fuse element in its securing position.

When the trigger is actuated, it is known that the closing slide slides backwards after firing. In addition, it is known to take place during the closing of the shutter re-loading a cartridge from the magazine into the cartridge chamber. Since the fall protection projects back into the path of movement of the firing pin by the action of the spring already at shutter return, unintentional firing can be effectively prevented.

Preferably, the trigger bar of the fall arrest comprises at least a second control contour in order to apply the control element in the case of trigger actuation and to transfer the securing element into its release position (claim 8).

Also, the second control contour can be provided in a simple configuration as a survey or tab with or without control slope to pressurize the control at trigger actuation. This measure ensures that with deliberate deduction actuation also firing is possible.

In addition, a known Züngelsicherung known per se may be provided on the trigger, which prevents unwanted actuation of the trigger and thus the trigger bar. During the withdrawal movement then the trigger bar rotates about its control contour, the fall arrester in the open position and ensures a firing. After firing the mass balanced fall arrest during backward movement of the closure is subject only to the force of the spring.

After completion of the shutter advance the control pin is located with its underside on top of the second control contour of the trigger bar. When the trigger is released, the control contour and the trigger bar move forward, with the spring-loaded trigger bar being pushed upwards and resuming its original position as soon as the control contour comes out of contact with the underside of the control pin.

In this initial position of the trigger bar, the trigger connected to the trigger rod is secured by the trigger tongue and forced the control of the fall arrest by the first control contour on the trigger rod, whereby the fall arrest is locked in its securing position and the cocked striker at Triggering of the sear by fall or shock acceleration is caught safely from the end of the fall arrestor.

The first and / or the second control contour exclude via the positive control of the securing element from any unwanted own movement of the securing element. The Applicant reserves the right to claim independent protection for such a trigger bar.

Preferably, the storage element of the fall arrest comprises a recess at least partially complementary in size to the firing pin guide sleeve for the bearing on the firing pin guide sleeve, such that the fuse element pivots with its movement from the securing position to the release position and vice versa to the firing pin guide sleeve (claim 9).

If the bearing element is designed, for example, as an axle pin, pin or pin, for example, the recess may extend in the upper, lower region or middle region of the bearing element and penetrate this approximately in a range of 10 to 50% of its maximum diameter. In order to enable pivoting, in addition, the outer edge regions of the recess are rounded to the outside to allow a corresponding movement of the firing pin guide sleeve.

Preferably, the fall arrester and in particular the firing pin comprises a projection formed thereon for the operative engagement with the securing element in its securing position (claim 10).

Such an approach can protrude, for example, from the firing pin down and can be realized with manufacturing technology simple means. The approach provides a suitable engagement surface for the fuse end of the safety lever.

FIG. 1 shows a tapeless self-loading pistol. 1 FIGS. 2 to 6 show individual elements of the gun 1 during and after firing, but without the fall arrest invention. The structure and operation of the fall arrester 59 according to the invention are then on hand of Fig. 7 to 16 explained.

FIG. 1 shows in outer view a self-loading pistol 1 with removed magazine 3. The self-loading pistol 1 comprises a handle 2 and a pipe 9 surrounding a closing slide 7. About a trigger 5 can be in the FIGS. 2 to 8 . 11 . 12 . 14 . 15 and 17 shown trigger mechanism in a known manner. By means of an external handle 15a, a disassembly shaft 15, not shown here, arranged in the grip 2 (see FIG Fig. 6 ) in a locked position or in a disassembly position.

The handle 15a has, in the locking position, also called clamping position, horizontal to the rear. It blocks, inter alia, a projection 12 on the underside of the tube 9 (see. Fig. 7 ), and thus prevents removal of the tube 9. In the disassembly position, the tube 9 and the closing slide 7 and the closing spring assembly 39 with the closing spring 41 and its pin 43 (see. Fig. 7 ) after release of a known closure catch lever 10 forward from the handle 2, since the projection 12 can slide over the disassembly shaft 15 away. A Such disassembly shaft is for example in the DE 10 2013 010 969.8 the applicant of the same name, which is incorporated herein by reference.

The catch lever 10 can catch and hold the shutter slide 7 in its catch position in a known manner. On the closing slide underside, a semicircular recess 6 is further provided which is positioned such that it turns the disassembling shaft 15 (see FIG Fig. 6 ) in their clamping or disassembly position - and only then, if previously the magazine 3 was removed from the magazine shaft 53.

FIG. 2 shows the gun 1 with cocked striker 17 before its triggering and knocking off. As is known, the following items are provided for firing: the trigger 5, the trigger guard 5e also known as safety lighters or trigger, a trigger rod 5 coupled to the trigger rod 27, a release latch 45 (see Fig. 3 and 4 ), a sear 19, the striker 17 with a lug 17a and the shutter carriage 7. The structure of these components and their interaction in firing and tensioning of the firing pin will be described below.

The trigger 5 is pivotally mounted about a trigger shaft 5a and by a leg spring 5b (see, inter alia Fig. 3 and 4 ) and a spring 37 (see, inter alia Fig. 3 and 4 ) in his in FIG. 2 biased rest position shown biased. The trigger 5 comprises on its rear side a shoulder 5c (cf. Fig. 6 . 11 . 12 . 14 and 15 ). 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 acting as a Abzugstangenlagerungsachse, the trigger 5 transverse to the weft direction in recesses 5f (see, inter alia Fig. 11 u. 12) passing through pin 5d coupled to the trigger 5 in terms of movement and pivotally mounted 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, inter alia Fig. 3 and 4 ). The trigger rod support in the handle 2 is shown schematically in FIG FIG. 6 shown. 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 at its upper end a upper flap 31 formed to the left side (cf. Fig. 4 ). The functions of the tabs 29 and 31 will be explained later.

A fuse 5e protects the trigger 5 in a known manner - for example in case of impact or shock accelerations - against an unwanted trigger trigger. This safety catch 5e is also mounted in the trigger on the trigger rod bearing axis 5d and is automatically pivoted upon actuation of the trigger to this axis and against a spring, not shown, located in the trigger, whereby the trigger against the handle is unlocked and pivoted to the trigger shaft 5a can.

The in the Figures 3 and 4 shown trigger pawl 45 is provided on the left side, at the rear end of the trigger bar 27. The trigger pawl 45 is pivotally mounted about a transverse to the firing direction passing through, used in the handle 2 Auslösekliniklagerungsachse 49. The use of the tripping bearing axis 49 in additional wall elements of the handle 2 is known and not shown. The trigger pawl 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 provided 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 firing pin 17 and pivotally mounted about a bearing axis 19b in the handle 2. At the rear end of the sear 19 protrudes approximately centrally a nose 19d backwards. Below the nose 19d includes an approximately rectangular recess, which is bounded below by a hook-like end 19e of the sear 19 (see. Fig. 2 to 4 ). In this recess, the release latch 45 engages with its lower tab-shaped end (see. Fig. 3 and 4 ). An approximately centrally on the underside of the sear 19 provided, acting as a return spring 19c compression spring (see. Fig. 5 to 8 ) supports the sear 19 down in the handle 2 from. The support in the Handle 2 is shown schematically in FIG FIG. 6 shown. 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 the front end of its firing pin head 17g a firing pin tip 17c. From its firing pin tip 17c it thickened in an approximately cone-shaped rearward to a serving as a firing pin spring bearing annular shoulder 17d, in turn, followed by a portion 17b with a smaller diameter. A firing pin spring 17e surrounds the firing pin 17 and supports with its front end on the shoulder 17d and with its rear end to a provided in the firing pin guide 18, the firing pin 17 surrounding firing pin guide sleeve 18a. The firing pin guide sleeve 18a leads the rear end of the firing pin 17. The firing pin guide sleeve 18a has on its underside extending over about 4/5 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 18a is supported on the end and support piece 58 (cf., inter alia Fig. 2 . 5 . 7 and 8th ), in the inner contour of which spring-loaded dips and so the vertical to the firing direction in the rear part of the closure slide slidably mounted in a backdrop closing and Abstützstück 58 in - as in other pistols - known manner locked.

Further, at the rear end of the firing pin 17 of the downwardly projecting, the firing pin guide sleeve 18a in the longitudinal slot 18b passing through approach 17a is provided. Within the firing pin guide sleeve 18a is disposed a firing pin return spring 17f. This is supported with its rear end on the firing pin lug 17a and with its front end on the firing pin guide sleeve 18a and pulls at severed, in rest position firing pin 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 the leading with the shutter slide 7 firing pin 17 at its approach 17a. In the in FIG. 2 shown clamping position is the approach 17a with its lower front edge on the step 19f of the sear 19 and is held by this. The further advancing shutter slide 7 has the firing pin spring 17e clamped in a known manner against the firing pin spring bearing 17d, since the shutter slide 7 takes the firing pin guide sleeve 18a during further forward so that their front end compresses the firing pin spring 17. The trigger mechanism is ready to fire in this mutual operative connection.

Figures 3 and 4 show the cocked firing pin 17 at the moment of its release by the sear 19. The trigger 5 is pressed against the spring force of the leg spring 5b and the spring 37 to the rear. The pin 5d has taken the trigger rod 27 coupled thereto to the rear, wherein the front end of the trigger bar has moved on a circular path around the trigger shaft 5a to the rear top. The rear end of the trigger bar 27 is compared to FIG. 2 moved in the longitudinal direction to the rear bottom, wherein the lower flap 29 of the trigger bar 27 is guided out of a recess 24 in a breaker bar 21 to the rear out and so moves the rear end of the trigger bar 27 down. The upper tab 31 of the trigger bar 27 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 support shaft 49 to the rear bottom. The trigger pawl 45 has over its operative engagement the sear 19 against the spring force of the return spring 19c (see. Fig. 6 to 8 ) pivoted 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, in the cartridge chamber 51 (see. Fig. 2 and 5 ) provided on the cartridge and ignites a propellant charge in a known manner.

Fig. 5 shows the gun 1 with knocked-off firing pin and empty cartridge chamber 51. 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 cap of the cartridge, not shown, in the cartridge chamber 51. Rather runs at firing of the firing pin 17 due to its inertia on the in FIG. 5 shown position and compresses its return spring 17f in the firing pin guide sleeve 18a. After the flow and when the cartridge chamber is empty, the return spring 17f slightly returns the firing pin 17 until the firing pin head 17g bears against the firing pin spring bearing 17d.

The trigger 5 is in FIG. 5 pivoted 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 rod 27 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 according to Fig. 2 , as well as the catch 19 and the in Fig. 5 not shown release latch 45.

For re-tensioning the firing pin 17 and its firing pin spring 17e, the shutter slide 7 must be withdrawn until the sear 19 underlies the projection 17a. Thereafter, the shutter slide 7 is released again.

The structure and operation of the fall arrester 59 according to the invention will now be described with reference to FIG FIGS. 7 to 17 described.

The fall arrester 59 comprises according to FIGS. 7 to 17 the following interacting components: the trigger 5, the trigger rod 5 coupled to the trigger rod 27, a fuse element 61, a locking spring 69, the sear 19, the firing pin 17 with its lug 17a and the shutter slide 7. The interaction of these components will be described below.

Fig. 7 . 8th and 10 show partial views of the self-loading pistol 1 with the fall arrester 59 in various perspective views. Fig. 9 shows an enlarged view of the fuse element 61. First, the structure of the fuse element 61 will be explained.

The securing element 61 comprises a pin-like bearing element or axle pin 63, which tapers conically at its first or upper end 65. This end 65 is in the assembled state in a recess, for example. A bore (not shown) in the Inside the closure slide 7 rotatably inserted. At its second or lower end 67, the axle pin 63 thickens and merges into a two-armed lever. The lever comprises a first lever arm 66a with a first securing end 67a, which engages in its securing position in the path of movement of the projection 17a of the triggered firing pin 17. The second lever arm 66b lies with its free lever end 67b opposite the securing end 67a and comprises on its underside a control pin 73 which acts as a control element and projects vertically downwards. The flattening 74 and the non-circular configuration of the control pin serve a geometric optimization for adapting the contact surfaces.

The second lever arm 66b further comprises a substantially completely vertically penetrating approximately oval opening or a recess 71, which serves as a spring bearing of an arm of the leg securing spring 69. The leg securing spring 69 engages around the axle pin 63 on the upper side of the two-armed lever 67 and is supported by its second leg end on the inside of the closing slide 7. The leg securing spring 69 is designed to bias the securing end 67a into the securing position, in which it engages in the movement path of the firing pin 17 in order to catch it in the triggered state at its attachment 17a.

At the bottom of the securing end 67a approximately in the front third of the first lever arm 66a, a step 68 is provided, so that the height of the securing end 67a corresponds to the height of the recess 83 in the firing pin approach. In addition, at the top of the two-armed lever 67 recesses 72 (see. Fig. 11 ff.) Provided to provide space for between the shutter slide 7 and the top of the two-armed lever 67 lying leg of the spring 69.

The bearing pin 63 comprises on its side facing the firing pin guide sleeve 18a for bearing on the firing pin guide sleeve 18a a roof-like recess 75, for example, which is stronger towards its outer sides to a rolling or pivoting movement of the securing element 61 on the firing pin guide sleeve 18a for pivoting the securing element 61 between its securing position (see. Fig. 7 . 8th . 10 to 13b ) and its release status (cf. Fig. 14 to 16b ). At the firing pin guide sleeve 18a facing away from the bearing pin 63 comprises a circumferential groove 81 (see. Fig. 9 to 17 ) to make room for possible contamination between the axle and its bearings in the shutter slide 7.

Fig. 7 and 8th show the triggered firing pin 17 which is caught over the securing end 67a of the securing element 61. In this position, the firing pin can not touch a cartridge bottom of any cartridges located in the cartridge chamber and thus prevents a shot firing. The securing spring 69 biases the securing end 67a into this securing position. In addition, a trained on the trigger bar 27 control contour 77 behind the control bolt 73. As long as the trigger 5 is not actuated, the fuse end 67a can not swing out of the path of movement of the projection 17a on the firing pin 17. The control contour 77 is bent tab-like from the trigger bar 27 to the top left and thus forms a control bar, which corresponds in height approximately to the length of the control pin 73. At its front, the trigger 5 end facing the control contour 77 extends semicircular in the direction of the right side of the shutter slide 7, not shown here. When not actuated trigger this rounded area behind the control bolt 73rd

The adjacent to the control contour 77 portion of the trigger bar 27 has in the direction of the trigger 5 an approximately perpendicularly extending approximately slot-like recess 78. This is due to manufacturing technology.

The recess 78 is followed in the direction of the trigger 5 in the trigger bar 27 by a second control contour 79 which is approximately perpendicular to the top. This is formed at its recess 78 facing the end approximately wedge-shaped, wherein the rear part of the upper side of the control contour 79 in the direction of the recess 78 slopes downwards. At the chamfer closes in the direction of the trigger 5 approximately horizontally extending top of the control contour 79 at.

Fig. 10 shows the mounting of the securing element 61 on the firing pin guide sleeve 18a, wherein the recess 75 on the firing pin guide sleeve 18a partially rests.

In Fig. 11 is the securing element 61 in its securing position and the firing pin 17 is stretched and held at its lower end 17a of the sear 19 over its stage 19f and caught. The rotatable securing element 61 protrudes with its securing end 67a into the path of movement of the projection 17a on the firing pin 17. The opposite end 67b of the securing element 61 is positively backed by the control contour 77 on the trigger bar 27, so that the securing element 61 is rotated out of the securing position is hindered. In addition, the securing spring 69 biases the securing end 67a in the securing position. The trigger 5 is coupled to the trigger bar 27 via the trigger rod bearing axis 5d as stated above. In addition, the deduction is over in Fig. 7 and 8th shown deduction fuse 5e secured. Only when the trigger tongue 5e is actuated can the trigger 5 for the firing of the shot be moved backwards.

Fig. 12 shows the fall arrest and the securing element 61 in the securing position in which it has stopped the knocked-out or knocked-off firing pin 17 on its way towards the cartridge chamber. The release can be done, for example, by a movement of the sear 19 and / or the release latch 45 down, and thus the sear 19 with its step 19f down out of engagement with the firing pin lug 17a 17 passes. The firing pin 17 is then slid forward with its projection 17a over the step 19f of the sear 19 away in the direction of the cartridge chamber and finally caught by the securing end 67a of the securing element 61. The firing pin 17 sets a defined distance, which corresponds to the distance between the step 19f and the securing end 67a located in the securing position. The firing pin 17 is thus collected only at the last moment shortly before hitting the firing pin tip 17c on a cartridge bottom of a possibly located in the cartridge chamber cartridge.

Since the control contour 77 with its fuse bar downwardly projects the downwardly projecting control bolt 73, the securing element 61 can not turn in his captive firing pin caught by him and thus release the firing pin 17 unintentionally. The captured firing pin 17 is so far spaced with its firing pin 17c from a cartridge located in the cartridge chamber that he does not contact a primer such a cartridge or can touch. In addition, the trigger 5 and the trigger bar 27 are secured by the previously described trigger fuse 5e in a known manner, so that no unintentional movement of the trigger 5 and the trigger bar 27 can take place. In addition, the firing pin 17 and its firing pin spring 17e in the trapped position relaxed so far that the firing pin spring bearing 17d on the inside of the firing pin guide 18 (see. Fig. 5 ) and the firing pin return spring 17f begins to act to return the firing pin 17.

Even if a shooter with caught firing pin 17 the trigger 5 on the trigger fuse 5e (see. Fig. 2 ), the firing pin spring 17e can no longer move the firing pin 17 forward so far that the firing pin tip 17c can touch the cartridge base and thus a primer, so that inadvertent firing is prevented. Although the fuse end 67a releases the projection 17a on the firing pin 17 in the case of trigger actuation (see the following explanation of FIG Fig. 14 and 15 ), but the force of the firing pin spring 17e is no longer sufficient to move the firing pin 17 sufficiently forward. If a shooter now lets off the trigger 5 again, the securing end 67a again places behind the firing pin projection 17a and the self-loading pistol 1 is secured again. To tighten the firing pin 17 again, as shown at the beginning, a shooter must pull back the closing slide 7 and slide it forward.

Fig. 13a and 13b each show the captured firing pin 17 obliquely from the front up or down in a partial perspective view. The storage pin 63 rests with its securing end 67a facing the region of its recess 75 on the firing pin guide sleeve 18a and stands with its the fuse end 67a opposite side of its recess 75 slightly from the firing pin guide sleeve 18a.

Fig. 14 shows a release of the fall arrest and release the firing pin 17 by pressing the trigger 5. In Fig. 14 the firing pin 17 is still in his tense and held by the sear 19 state. In Fig. 15 the firing pin 17 is triggered and knocked off via the actuation of the release latch 45 and catch 19 and the associated release of the firing pin projection 17a. At the Pushing the trigger 5 to the rear is the trigger bar 27, as stated at the beginning of the stop 47 of the release latch 45 at. Upon displacement of the trigger bar 27 to the rear of the control pin 73 of the fuse element 61 slides along the strip-shaped control contour 77 on the rounding and beyond the recess 78 addition, until it is acted upon by the second control contour 79 of the trigger bar 27 with its inside. The control contour 79 acts on the control pin 73 such that the securing end 67a is pivoted out of the path of movement of the firing pin projection 17a against the resistance of the securing leg spring 69. In this case, the recess 75 rolls on the firing pin guide sleeve 18a. This ensures that the securing element 61 is in its release position before the sear 19 is triggered via the release latch 45 and the withdrawal rod 27.

In the release position, the way for the firing pin lug 17a is free and the triggered and knocked firing pin 17 can touch with his firing pin tip 17c the primer of any cartridge located in the chamber.

Fig. 15 shows the severed firing pin 17 in its foremost position at the moment of ignition. The trigger bar 27 has the nose 47 acted on the trigger pawl 45 and thereby brought the sear 19 out of engagement with the lug 17 a of the firing pin 17. A return of the closing slide 7 has not yet begun. The firing pin 17 has a compared to Fig. 12 longer distance covered over the fuse end 67a addition.

Fig. 16a and 16b also show the triggered firing pin 17 in its foremost position and the fuse element 61 in its release position once in a perspective view obliquely from the front up and down. Especially Fig. 16b (see also Fig. 13b ) shows a recess 83 in the projection 17a of the firing pin 17 with a complementary to the securing end 67a oblique surface, which ensures a catching of the firing pin lug 17a on the securing element 61. In addition, it is shown how the bearing pin 63 via its recess 75 on the firing pin guide sleeve 18a when turning or pivoting the securing end 67a of the firing pin guide sleeve 18a on the roof trained upper edge unrolls and now with its the firing pin tip 17c facing portion of the recess 75 rests against the firing pin guide sleeve 18a.

Fig. 17 finally shows the after firing after the shot again with his firing pin 17a on the sear 19 and their stage 19f captured firing pin 17. The firing pin spring is stretched and the trigger 5 is still in its rear actuated position. The shutter slide 7, not shown here, has run to the rear and again after a shot release. As an alternative to firing a shooter can also manually retract the shutter slide 7 and let it run forward again, with appropriately actuated trigger.

During the shutter slide return, a non-recessed area 8b of the closing slide 7 (cf. Fig. 6 ) the interrupter rod 21 at the elevation 33 down and takes on the voltage applied to the interrupter rod 21 lower tab 29 of the trigger rod 27 with this down. As a result, the upper tab 31 of the trigger rod 27 slides down into a 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 striker 17 is caught again. This interaction of the closure slide with the trigger mechanism is further explained in a parallel patent application by the same filing date entitled "Device for preventing the tensioning of the firing pin", to which reference is expressly made.

The securing element 61 is pivoted by the securing spring 69 in its securing position. During the movement of the interrupter rod 21 and thus the trigger bar 27 down the trigger rod 27 slides down out of engagement with the control pin 73 of the fuse element 61. With again leading closure 7 and released trigger the trigger rod 77 comes with its control contour 79 in contact with the Underside of the control pin 73 of the securing element 61 until the leading trigger rod 27 assumes its front end position, is pushed up by the spring 37 and after overrunning the control pin 73 with its first control contour 77 behind the control bolt 73 again.

If a shooter now lets go of the trigger 5, the trigger 5 moves forward again due to the force of the trigger leg spring 5b, taking the trigger rod 27 in its forward position in cooperation with the spring 37. This corresponds to the basic position with relaxed trigger 5 off Fig. 7 , In this case, the lower flap 29 of the trigger rod 27 slides back into the recess 24 of the interrupter rod 21 and the upper tab 31 of the trigger rod comes again in front of the nose 47 of the release latch 45 to lie. The control pin 73 slides over the front bevel of the control contour 79 via the recess 78 in front of the first control contour 77, where he is again behind the rounded ledge area of the control contour 77. The cocked firing pin 17 can now 45 by triggering the trigger fuse 5e and the trigger 5 on the upper tab 31 of the trigger rod 27 and the nose 47 of the trigger pawl 45 are triggered again.
