Description

DESCRIPTION

Firing pin safety

The invention is concerned with at least one, preferably a plurality of firing pin safety (s) of a firing pin incorporated in a locking system of a foreign or self-propelled weapon, wherein it must be ensured that a shot is triggered only when the closure is locked with a gun barrel. For this purpose, the firing pin is secured with at least one Schlagbofzensicherheit against unwanted triggering.

From DE 10 2009 056 735 A1, a foreign-powered weapon with an ammunition supply is known in which the ammunition is placed in front of the closure and this is linearly supplied by the closure to a weapon barrel. In one of the switching cycles, the closure is locked with the gun barrel and ignited the ammunition or cartridge. This ensures that the ignition takes place when the lock is fully locked.

A selective and switchable closure and / or ammunition drive are disclosed in DE 10 2010 051 047 A1 and DE 10 2010 027 636 A1. Again, a lock security is required.

The object of the invention is to demonstrate this lock security for such weapons systems.

The object is achieved by the features of claim 1 Advantageous embodiments are listed in the dependent claims.

The invention is based on the idea to provide a lock security by at least one integrated into the locking system firing pin safety. In continuation of this Idea are further fuses regarding an unwanted ignition of an ammunition provided by the firing pin.

The transport of the closure is, as described for example in DE 10 2009 056 735 A1, hereby assumed or assumed, to which reference is hereby made. The closure system comprises a closure carrier for receiving and transporting a closure. The closure may be formed by a closure head.

Attached laterally to this closure carrier is a leading ram which abuts against a weapon-resistant locking sleeve, while the closure head approaches the locking portion of the weapon barrel. The fastener carrier is moved further in the direction of the weapon barrel. By the abutting the locking sleeve plunger, which can now no longer be moved, there is the tensioning of a firing pin located in the closure. The continuing closure carrier continues to move so that the closure head on / in the locking sleeve can engage the locking arms of the weapon side and lock the closure head. There is a locking of the closure via a bolt on the closure head, which is guided along a locking curve in the lock carrier when the lock carrier is still slightly led forward. Moving the bolt along the locking cam causes the locking head to rotate to unlock the lock.

In this time sequence also takes place the tensioning of an advance spring within the plunger and a spring of the firing pin through the rear part of the plunger, which assumes a firing pin main flag of the firing pin. When the lock head is rotated to lock in the lock carrier, the main striker flag moves to the rear of the slide and is released thereby allowing a shot to be fired. For this release, the rear part of the plunger has a shape that allows the striker lug to slide forward along a so-called trigger edge in the regular course of the closure's locking. This shape forms the cam for the main firing pin. In order for the rear part of the plunger to be able to grasp behind the main slide flag again after the shot has taken place, the rear part of the plunger can be disengaged so that the firing pin flag can engage again behind the rear part of the plunger when the closure head is turned back for unlocking. The at least one fuse results in the interaction with the possibility of the weapon to fire single fire as well as continuous fire. This design can be considered as the first Schlagboizensicherung, resulting from the actual weapon function. For this purpose, a second Schiagbolzenfahne is functionally connected to the first firing pin main lug on the firing pin itself and serves for the so-called sniper operation. When turning the bolt head, this second firing pin flag is guided behind a trigger. Only the deliberate release of the trigger lever causes the firing pin to be released via the second firing pin lug only by the trigger. The release can be done as for the single fire, by a magnet with a plunger element. For a continuous fire, the trigger is preferably controlled. Although the firing pin main flag is exposed at the trigger edge of the rear part of the plunger, the firing pin is held securely in this position because the firing pin with the second firing pin flag is behind the trigger.

In response to possible breakage of the plunger in the feed position, that is to say when the striker is tensioned, in a further variant, an intermediate or displacement sleeve is incorporated between the closure head and the closure carrier. This prevents the firing pin from being triggered in this situation. The firing pin can strike a maximum of the sleeve edge at break of the plunger and is thereby held at this. The firing pin can not hit or penetrate the firing cap of the cartridge. Furthermore, it is provided that in this intermediate sleeve a slope (slope) is involved. Thus, when unlocking and before the locking head is unlocked, the firing pin on the firing pin flag is transferred to a safety position.

Also with regard to the fracture of the firing pin itself, the present invention provides its own (further) security. For this purpose, a separate bolt is integrated, which engages in a recess of the firing pin. The bolt is in turn controlled during rotation of the closure head in the locking sleeve out of the firing pin and releases the firing pin. For this purpose, the bolt on an upper rounding, which cooperates with a curve in the closure sleeve. Only a complete locking causes the release of the firing pin.

Proposed is a first safety device for a closure system for a particular foreign-powered weapon with a trigger and with a closure carrier, a bolt supported by the closure carrier and a therein striker, which has a Schiagboizenfeder, wherein a firing pin flag the firing pin at the end of the firing pin when turning the lock head for locking behind the trigger lever of the weapon and is assumed by this. The firing pin also has a firing pin main flag, which are functionally connected to the firing pin flag on the firing pin. The firing pin main flag is in turn secured by an intermediate sleeve between the bolt carrier and the Verschiusskopf against unwanted triggering. These safety devices are supplemented by a further firing pin safety device, which has a bolt with a passage through which the firing pin is guided. A nose of the bolt engages in the recess of the firing pin and is guided when turning the closure head from or into the firing pin.

Shown in FIG. 1 is a locking system 1 and at least one security system 10, 40, 50 of a weapon (not shown) with a guide part 100 for the locking system 1.

The closure system 1 comprises a closure support 2 and a closure head 3, which is carried in the lock carrier 2 and guided by this in a front or rear position, in the front position of the closure head 3 is locked via its locking head warts 3.1 with a gun barrel (not shown) , In the rear position, the closure or the closure head 3, a new cartridge (not shown) presented. This process is described in more detail in DE 10 2009 056 735 A1, to which reference is hereby made.

Furthermore, the closure system 1 comprises a plunger 4, which is preferably integrated laterally on / in the closure support 2 or fastened in this. This spring-loaded plunger 4 points in the weft direction. In addition, an angle lever 5 is incorporated, which, as will be explained, acts as a lock for a bolt 6, which is responsible for locking the closure or the closure head 3. A firing pin spring of a firing pin 7 is marked with 7.1.

Fig. 2 shows the closure system 1 in a side view pointing in the weft direction.

Fig. 3 shows the essential details of an arms-side locking device 15. This has in its locking sleeve 1 a passage 11.1 for the closure head 3. The implementation 11.1. includes locking lugs 11.2 (preferably as a pair), which are matched to the locking head warts 3.1 and via which the locking of the closure takes place in the weapon. Laterally adjacent to the bushing 11.1, a stop surface 11.3 is integrated, on which the plunger 4 impinges when the closure carrier 2 transfers the closure head 3 to its front position and is driven through the bushing 11.1.

4 and 5 show in a sectional view the angle lever 5 in function and a control cam 14 on the guide part 00. The angle lever 5 engages in function in a recess 3.3 of the closure head 3 from below, while the Verschiussträger 2 and the shutter 3 in the locking position to be brought. In Fig. 6, a closure sleeve 20 is shown as a security system 10. FIG. 7 shows the closure and security system 1, 10 seen in the weft direction.

Fig. 8 shows the further firing pin safety device 50, which acts in conjunction with a control cam 11.5 in the locking sleeve 11. The firing pin safety device 50 is in this case a bolt which has a passage 51 through which the firing pin 7 is guided. A nose 53 of the bolt engages in a recess 7.4 of the firing pin 7. The bolt 50 has a semicircular upper outer shape 52, which is matched to the control cam 11.5 of the locking sleeve 11 of the weapons-soapy locking sleeve 15 (FIG. 9). With 54 a pin-like extension is marked, which rests on the angle lever 5 during the closure transport.

In Fig. 10 is a triggering device 42 of the safety system 40, here with a magnet 43 which moves a plunger 44 which acts on the trigger 41. The trigger 41 is spring assisted by a spring 41.1. The firing pin 7 is unstressed in this illustration. The triggering device 42 can also be used in particular for the sniper operation of the weapon.

The general locking procedure is as follows;

The lock carrier 2 is moved linearly and in a vertical plane within the weapon by a drive 30 (FIG. 1), not shown further, in and against the weft direction, the lock or the lock head 3 being moved into its front and rear positions.

In order to avoid that the bolt 6, which serves as Verriegeiungsbolzen the closure system 1, already begins to rotate due to its inertia in the lock carrier 2, without the closure head 3 would move forward, the angle lever 5 in the lock-1 and security system 10 integrated. The angle lever 5 forms the lock for the bolt 6 so that it can not move independently. Reached the lock carrier 2 the area of the Verriegelungshüise 11, the angle lever 5 along the control cam 14 from the recess 3.3 and thus lowered relative to the closure head 3, so that the angle lever 5 releases the lock head 3 for turning / locking. A spring 5.1 at Winkelhebe] 5 supports the function of Winkeihebels. 5 When the lock carrier 2 has reached the locking sleeve 11, the shock hits! 4 with its tip 4.5 on the stop surface 1 1.3 of the locking sleeve 11. The plunger 4 is leading, so that a projection spring 4.2 at the end 4.3 of the plunger 4 is tensioned before the collar 3.2 of the shutter 3 abuts against the locking sleeve 11. The plunger 4 assumes the firing pin 7, wherein in particular the end 4.3 of the plunger 4 a striker main flag 7.2 of the firing pin 7 assumes. The tensioning of the preliminary spring 4.2 takes place over a small distance (depending on the path of the tip 4.5). The plunger 4 itself now has no way to continue to be led forward.

However, the closure support 2 continues to run until the closure head 3 with its collar 3.2 has reached the passage 11.1 and thereby the locking lugs 11.2. With the assumption of the firing pin main flag 7.2 by the plunger 4, the firing pin spring 7.1 is stretched.

During the subsequent movement of the closure carrier 2, the locking bolt 6, which has been released, is guided along its locking curve 2.1 in the closure carrier 2 (top). With the passage of the locking cam 2.1 through the locking pin 6 (D ^, there is a rotation (D ₂ ) of the closure head 3 by about 30 ° and thus the locking of the closure or the closure head 3 in the locking sleeve 11. This attack the locking lugs. 1 1.2 as well as the locking head warts 3.1 behind or in one another (with pairwise integration) .The locking head 3 is locked in the weapon The unlocking and retraction of the locking system 1 takes place in opposite directions according to the individual locking steps for the locking.

With the rotation of the closure head 3 in the closure support 2, the main striking lug 7.2 also rotates so that it can move forward over a withdrawal edge 4.4 of the tappet 4. The firing pin 7 in the closure head 3 can move under the force of the firing pin spring 7.1 forward, a shot is fired.

The end 4.3 of the plunger 4 has for the shot firing on a shape that allows the striker main flag 7.2, in the regular course of Verriegeins the shutter along the so-called trigger edge 4.4 on the plunger 4 to slide forward, whereby the firing pin 7 is released , The shaping forms the control curve for the Schlagbofzen main flag 7.2. So that the end 4.3 of the plunger 4 can again reach behind the firing pin main lug 7.2 after the shot has taken place, the end 4.3 of the ram 4 can be deactivated so that the firing pin lug 7.2 lies behind the end 4.3 of the ram 4 can intervene. In a preferred embodiment, the end 4.3 and the striker main flag 7.2 are fork-shaped and engage with each other.

Another fuse 40 results in interaction with the possibility of single fire and continuous fire. This construction can be considered as a third fuse 40, although the actual function of the weapon function is due. A second firing pin tab 7.3 is operatively connected to the first firing pin main tab 7.2 via the firing pin 7 itself and serves for the so-called sniper mode (FIG. 1). When turning the closure head 3.1, this second firing pin flag 7.3 is guided behind a trigger 41. Only the deliberate triggering causes the second firing pin flag 7.3 to be released by the trigger 41. The release can be done for the single fire by the magnet 43 with a plunger element 44 (FIG. 10). For a continuous fire, the trigger 41 is preferably controlled. Although the firing pin main lobe 7.2 exposed at the trigger edge 4.4 of the end 4.2 of the plunger 4, the firing pin 7 is held securely in this position, since the firing pin 7 with the (second) firing pin flag 7.3 behind the trigger lever 41.

To avoid that the firing pin 7 can be triggered unintentionally, for example, because the plunger 4 breaks in feed position and thus when tensioning the firing pin spring 7.1 of the firing pin 7, the backup system 10 sees an intermediate sleeve 20, also called closure sleeve, between the Verschiusskopf 3 and the closure carrier 2 ago. If the plunger break 4 and thus subordination of the firing pin main flag 7.2 are repealed, this can maximally on the edge 22 of the closure sleeve 20 pitch, so that the firing pin 7 itself is not released for his entire path to the shot firing. While the closure head 3 remains in the respective position in its standstill times, the non-rotatably engaged closure sleeve 20 (FIG. 7) is in turn in motion (linear).

The continuation of the increase in safety can be integrated into a slope or bevel 21 in the edge 22 of the closure sleeve 20. The front (upper) straight line 21.1 form a safety position and the rear (lower) 21.2 a tee position of the firing pin 7. Already when unlocking but before the shutter 3 is unlocked, is due to the rotation of the shutter 3 due to the operation of the locking pin 6, the now the locking curve 2.1 moves in the opposite direction and the locking head 3 rotates counter to the rotation D ₂ , the firing pin main flag 7.2 transferred over the slope 21 in its safety position (Fig. 7). Should the disruption Break 4, the firing pin 7 can not break forward, the locking sleeve 20 holds the firing pin 7 on the upper straight 21.1 of the slope 21 firmly.

A further fuse 50 can be introduced independently of the latter fuse 40 as a simple firing pin safety device in the closure system. For this purpose, a recess 7.4 is provided in the firing pin 7, in which a latch 50 engage and can fix the firing pin 7. The bolt 50 has for this purpose a passage 51 through which the firing pin 7 is guided. A nose 53 engages in the recess 7.4 of the firing pin 7. When turning the closure head 3 and the bolt 50 is rotated, which is guided along the control cam 11.5 in the locking sleeve 1 1, whereby a Aussteuern of the bolt 50 with its nose 53 from the recess 7.4 of the firing pin 7 is achieved. The firing pin 7 is exposed. The entry of the bolt 50 in the recess 7.4 in the firing pin 7 during unlocking and return of the closure head 3 is spring-assisted. If, on the other hand, no or insufficient locking takes place, the bolt 50 remains in its position or is only slightly moved and holds the firing pin 7 firmly.
