Definitions

  • the invention relates to a repeating bushing with a lock mounted in a housing, which can be actuated via a bolt handle, the lock of which has a firing pin with a firing pin spring, which can be tensioned by means of a tensioning drive from a securing position via a trigger stud engaging the firing pin and provided on a pivot lever, whereby the swivel lever of the trigger shaft is supported on a trigger lever that can be pivoted via a trigger
  • the pivot lever of the trigger stud is supported on the side opposite the linkage on the tensioning lever on a trigger lever which is pivotally mounted in the housing and can be actuated via a trigger off, so that the swivel lever of the trigger stud can be tensioned over the tensioning device to tension the firing pin spring and to unlock the lock.
  • Trigger lug over the firing pin spring causes the trigger lug to pivot out of the path of the firing pin, which thus rushes against the barrel by the firing pin spring and triggers the shot.
  • the leaf spring acting on the swivel lever of the trigger gallery presses the trigger gallery back against the path of the firing pin, which is caught by the trigger gallery when the bolt is pulled back to eject the cartridge case and to load a new projectile.
  • the cocking slide has to be adjusted in opposite directions, whereby the cocking lever moves the swivel lever of the trigger collar into the securing position in which the swivel lever of the trigger collar overlaps the trigger lever by the displacement path, which improves safety an unwanted release of the firing pin increased.
  • a disadvantage of this known construction is, above all, that the forces to be applied to tension the firing pin spring via the cocking slide are comparatively large, because the lever linkage of the cocking drive with the available travel of the cocking slide cannot achieve a sufficient ratio to reduce the cocking drive with a small amount Easily handle effort
  • the invention is therefore based on the object of designing a repeating bushing of the type described in such a way that the tensioning drive for the firing pin spring can be actuated without any particular effort
  • the invention solves this problem in that the pivot lever of the trigger gallery and the trigger lever on a parallel to the firing pin in Carriage guided and connected to the tensioning drive are mounted on which acts on at least one compensation spring which acts in the opposite direction to the firing pin spring
  • the actuating force to be applied via the tensioning drive can be reduced by the force of the compensating spring, so that the actuating forces to be applied via the tensioning drive differ from the difference in the Forces of the firing pin spring and the compensating spring depend on the fact that both the pivot lever of the trigger stud and the trigger lever for securing the pivot position of the trigger stud are mounted on the slide, the spatial assignment of these construction parts is retained during the securing and unlocking, which is an essential prerequisite for the required high Functional safety represents and the Qualltat the draw conditions significantly improved
  • the tensioning drive can be designed differently, there are particularly simple design conditions if it consists of a crank drive that can be actuated by means of a handwheel. This type of tensioning construction is possible despite the limited transmission ratio of the crank drive because the actuating forces to be applied for the tensioning drive are determined independently of the tensioning force of the firing pin spring A significant part of this clamping force for the firing pin spring can be applied by the compensating spring if it is designed accordingly. Because of the compact space available, it is advisable to provide two helical springs arranged to the side of the slide instead of a larger compensating spring Support the slide and the other side on the housing
  • the slide can be locked using the tensioning drive.
  • a tension drive design as a crank drive this is structurally simple to solve if the crank drive has an over-center position in the unlocked position of the slide.
  • the slide movement between a safety and an unlocking position can be used for an additional locking of the trigger lever in the locking position if the housing forms a locking stop for the trigger lever in the locking position of the slide. In order to release the trigger, it is imperative to move the slide out of the locked position.
  • the position of the firing pin can be displayed in a simple manner via an approach provided on the firing pin and protruding from the lock in the unlocking position.
  • the firing pin can be preceded by an ignition pin supported by a compression spring on the firing pin, which is connected to a signal rod guided in the lock parallel to the firing pin. Due to the spring loading of the firing pin, it rests against the base of the cartridge, regardless of the position of the firing pin that strikes the firing pin to trigger the shot. In the absence of the cartridge, the firing pin is pushed into the cartridge chamber with limited stops, which is accompanied by a corresponding displacement of the signal rod, at the position of which the presence of a cartridge can thus be monitored during the barrel.
  • FIG. 2 shows the clamping drive for the firing pin spring in the securing position on a larger scale
  • FIG. 3 shows a section along the line III-III of FIG. 2
  • FIG. 4 shows a representation of the tensioning drive corresponding to FIG. 2, but in the unlocking position with the firing pin spring tensioned
  • FIG. 5 shows a section along the line V-V of FIG. 4.
  • the repeating rifle shown for example has a housing 2 inserted into a shaft 1, to which a barrel 3 is connected.
  • the cartridge chamber 4 of the barrel 3 is closed off by the head 5 of a closure 6, which receives a lock 7 and can be actuated with the aid of a conventional chamber handle.
  • the breech head 5 can be locked with the barrel 3 and unlocked after the shot, to pull the empty cartridge case out of the cartridge chamber 4, to eject it and to eject a new cartridge from into a magazine receptacle 9 of the housing 2 promote used magazine in the cartridge chamber 4.
  • the lock 7 of the closure 6 consists of a firing pin 10 which is loaded by a firing pin spring 11.
  • This firing pin spring 11 is supported on the one hand on the front firing pin end 12 and on the other hand on a firing pin guide 13.
  • this tensioning drive 15 consists of a crank drive, the crank of which is designed as a handwheel 16 and via a link 17 is connected to a carriage 18.
  • the chute 18 is guided in a sliding guide 19 of the housing 2 parallel to the firing pin 10 and consists of two side cheeks 20, which are connected via a web 21 and the articulation axis 22 for the link 17 of the tensioning drive 15 With the articulation axis 22 projecting over the side cheeks 20 and over the web 21, the slide 18 engages in the displacement guide 19 of the housing 2.
  • two compensation springs 23 are supported, which find their opposite abutment in the housing 2, as can be seen in particular in FIGS. 3 and 5.
  • a pivot lever 24 for a trigger lug 25 is rotatably mounted, which interacts with the catch lever 14 of the firing pin 10.
  • This pivot lever 24 for the trigger lug 25 is supported on a trigger lever 26 which, like the pivot lever 24, is rotatably held between the side cheeks 20 of the carriage 18.
  • the trigger 28 is in the form of a piercer, which of course is not mandatory.
  • the trigger 28, which is pivotably mounted in a bracket housing 30 about an axis 29, carries an actuating lever 31 which can also be rotated about the axis 29 and which interacts with a spring-loaded pawl 32 which is mounted in the bracket housing 30 and which can be released via the trigger 28.
  • actuating lever 31 which can also be rotated about the axis 29 and which interacts with a spring-loaded pawl 32 which is mounted in the bracket housing 30 and which can be released via the trigger 28.
  • a pin 34 mounted in the trigger lever 26 and loaded by a plunger spring 33 acts on the actuating lever 31, so that when the trigger 28 is actuated, the actuating lever 31 is released by the pawl 32 and the Trigger 28 is pivoted under the action of the piercing spring 33 until a pin-like stop 35 of the trigger 28 acts on a trigger arm 36 of the trigger lever 26, so that the trigger lever 26 releases the pivot lever 24 with the trigger lug 25, which causes the pivot lever 24 to pivot out as a result of the load pulls over the catch hook 14.
  • the released firing pin 10 is thus moved via the firing pin spring 11 against the barrel 3, one of which Firing pin 10 upstream firing pin 37 triggers the ignition of the cartridge in the cartridge chamber 4 of the barrel 3.
  • the carriage 18 engages with 5 driver lugs 38 on the side cheeks 20 in guide recesses 39 of the trigger 28, so that when the slide is adjusted in the guiding sense of the firing pin spring 11, the trigger 28 is also adjusted via the driver lugs 38 if he is stabbed.
  • a torque is exerted on the trigger 28 when the slide 18 is moved into its front securing position by the driver lugs 10 38, which leads to a release of the pawl 32 with the effect that the released actuating lever 31 due to its load by the piercing spring 33 the trigger 28 is pivoted into the pierced stop position shown in FIG. 2.
  • the housing 2 forms a locking stop 41 for the trigger lever 26 in the locked position of the slide 18, which is thus additionally supported in the locked position of the slide 18.
  • the firing pin 10 forms an extension 42 at its rear end, which is only visible when the firing pin spring 11 is tensioned through an opening 43 in the closure cap 44.
  • the position of the firing pin 10 is thus readily recognizable.
  • the presence of a cartridge in the cartridge store 4 of the barrel 3 can also be indicated.
  • the ignition pin 37 is supported according to FIG. 1 via a compression spring 45 relative to the firing pin 10 and connected to a signal rod 46 which is axially displaceable relative to the driving pin 10 and is dimensioned such that it protrudes from the closure cap 44 when the firing pin 37 is pressed against the bottom of a cartridge by the spring 45. This position of the ignition pin 37 is indicated in FIG. 1.
  • the ignition pin 37 is inserted into the cartridge chamber 4 via the spring 45 until the ignition pin 37 strikes the closure head 5 with a stop 47. In this stop position, the free end of the signal rod 46 lies within the closure cap 44, as a result of which it is immediately apparent whether a cartridge is in the barrel 3 or not. Because of the resilient support of the firing pin 37 relative to the firing pin 10 and the displaceable guidance of the signal rod 46, this cartridge display is independent of the position of the firing pin 10.
