Definitions

  • the invention relates to a trigger device for automatic handguns, with a cock exciting when the breech closes, a breech controlled by the breech, which locks the cock during the breech procedure, a trigger slide which can be moved from a starting position into a single and a continuous fire position by the trigger against spring force and depending on the trigger slide position penetrating into the path of movement of a tap approach, interacting as a trigger and breaker lever pair.
  • the tap is released by moving the trigger across a tap, while at the same time the interrupter penetrates the path of this tap and automatically catches the tap in the cocked position during the next return movement, so that only one shot can break at a time.
  • the trigger is released, the trigger is moved back, which now engages over the tap approach, while the interrupter leaves the approach path after the tap approach has been transferred to the trigger.
  • triggers and interrupters have either been designed as standing levers which can be pivoted about transverse axes (AR-15, M 16 ASSAULT RIFLE HANDBOOK, FIREPOWER PUBLICATIONS, 1985, pages 108 and 109) or as push-adjustable levers (EP-OS184581), so that there is a considerable height and a corresponding distance between the handle and recoil line of action, which affects the handiness and accuracy of the weapon.
  • the known trigger devices are complex and are composed of expensive precision parts to be manufactured with narrow tolerances.
  • the invention is therefore based on the task of eliminating these deficiencies and creating a trigger device of the type described above, which is characterized by its as short and short construction as possible, from proportionally there are simple, rationally manufactured parts and a reliable trigger actuation that is not susceptible to faults.
  • the invention solves this problem in that the trigger and interrupter levers are pivotally mounted about a common upright axis of rotation and form a control link between one another by mutually opposite control edges, in which a sliding block movable via the trigger slide engages, the control movement of the sliding block relative to the control edges of the control link when pulling the trigger the pair of levers against the force of a return spring from a starting position, in which the trigger lever detects the cocking of the cocked cock, into a single fire position, in which the triggering lever releases the cocking neck and the interrupter lever penetrates into its approach path, or can be pivoted into a continuous fire position, in which Both levers release the tap approach, trigger and interrupter lever result in a kind of lying scissors, which is very flat and short and works exactly through a comparatively simple setting control.
  • the trigger and interrupter lever can be pivoted relative to one another and in relation to the hammer approach path depending on the individual or continuous firing position, so that the levers perform their tasks as a trigger and interrupter in a robust and functional manner Fulfill single fire and continuous fire perfectly.
  • the sliding block which is preferably designed as a control roller, is seated on a control lever which is pivotably mounted on one end about a parallel axis to the axis of rotation of the pair of levers and on the other hand engages in a driving slot of the trigger slide.
  • the catch surface of the interrupter lever assigned to the tap approach is offset in relation to that of the trigger lever in the opposite direction of the tap, a safe transfer of the cock caught by the interrupter lever to the trigger lever is ensured, since the trigger lever in any case up to its point due to its recessed catch surface proper swing position can swing into the hammer approach path before the interrupter releases the approach and this is only held by the trigger lever.
  • a simple construction also results if a leg spring which compresses the pair of levers serves as a return spring and a fuse is provided which fixes the trigger lever in the starting position.
  • the leg spring guarantees the perfect interaction between the control edges and the sliding block and the securing prevents the trigger lever from swiveling unintentionally in the initial position in the event of vibration and the like.
  • the fuse can advantageously consist of a stop-limited on the control lever and pivotably mounted against spring force, two-armed locking lever, one lever arm protruding into the path of movement of the stopcock forming a sliding surface on the side facing away from the closure and the other lever arm or a detent locking in the starting position with the release lever. the like having. If the control lever is in the starting position, there is therefore inevitably also a mechanical locking of the trigger lever, which is released automatically when the control lever is pivoted for firing the shot. However, in order not to prevent the release lever, the locking lever is pushed aside by the tensioning cock and the lock is briefly opened so that the trigger lever with its catch surface can dodge the tap approach and the unimpeded tensioning of the tap and its catch by the interrupter lever.
  • a trigger device for an automatic handgun (not shown) with a tap firing consists of a housing 1, in which a cock 4 loaded by a cock spring 3 is pivotally mounted about a horizontal axis 2.
  • the cock 4 is tensioned when the closure 5, which is only indicated, drops and is locked by a closure-controlled fire lever 6 during the closure process by reaching under a catch nose 4a by means of a hook part 7.
  • a trigger slide 8 is guided against the force of a trigger spring 9 from an initial position to a single and a continuous fire position, which trigger slide 8 is operatively connected to the trigger in a manner not shown.
  • a control lever 10 is now pivoted via the trigger slide 8, which is pivotally mounted on one end about a vertical axis of rotation 11 and on the other hand engages in a driving slot 12 of the trigger slide 8.
  • On the control lever 10 is a control roller 13 serving as a sliding block, which is formed between a pair of levers 14, 15 Control link 6 engages.
  • This pair of levers is composed of the trigger lever 14 and the interrupter lever 15 and is pivotably mounted about a common vertical axis 17, wherein a leg spring 18 presses the lever pair 14, 15 against each other.
  • the closure 5 In the initial position shown in FIG. 2, the closure 5 is in the forward position and the continuous fire lever 6 releases the cock 4 that is cocked, which is now caught by the trigger lever 14, which engages over a cock extension 21 with a corresponding catch surface 22.
  • the interrupter lever 15 lies with its catch surface 23 outside the movement path of the tap attachment 21. The weapon is ready to fire.
  • the control lever 10 pivots about the pivot axis 11 and the moving control roller 13 presses the trigger lever 14 outwards, so that the cock 4 is released and can trigger the shot (Fig. 3).
  • the interruption lever 15 moves inward through the return spring 18 and penetrates into the path of this tap attachment 21, so that the tap 4 again tensioned by the retracting closure with its tap attachment 21, which has a corresponding sliding surface, pivots back must displace the interrupter lever 15, which in turn immediately resumes its catch position (Fig. 4).
  • the catch surface 23 of the interrupter lever 15 catches the tap attachment 21.
  • a second shot is no longer possible when the trigger is pulled and only a release and renewed actuation of the trigger allows the next shot to be fired.
  • the trigger spring 9 pushes the trigger slide 8 back into the starting position; the control roller 13 pivots back and presses the interrupter lever 15 away from the tap shoulder 21, so that the interrupter lever 15 transfers the tap 4 to the trigger lever 14 which has been swiveled in in the meantime.
  • the catch surfaces 22, 23 of the trigger and interrupter lever 14, 15 are offset in height from one another, which can be seen from FIG. 1. After the transfer, the cock 4 is again held only by the trigger lever 14 (Fig. 2), so that the next shot can be fired.
  • the trigger slide 8 must be moved beyond its individual fire position into its continuous fire position, as indicated in FIG. 5, whereby the control lever 10 is pivoted accordingly and the control roller 13 the lever pair 14, 15 until the tap approach is fully released 21 opens.
  • the continuous fire lever 5 alone determines the locking and releasing of the tap 4, so that continuous fire is fired as long as the trigger remains actuated. Letting go of the trigger brings the trigger slide 8 back into the starting position and the control roller 13 in turn allows the pair of levers 14, 15 to engage in the trigger sequence, so that the next time the cock 4 is pivoted back, the stopper 21 is gripped by the interrupter 15 and transferred to the trigger lever 14 . 2 has been reached again.
  • This fuse consists of a two-armed locking lever 25 which is pivotally mounted coaxially to the control roller 13 on the control lever 10 and is held in a locking position by a locking spring 26 relative to the control lever 10. In this locking position, in which one lever arm 27 of the locking lever lies covering above the control lever, in the starting position of the pair of levers 14, 15, a locking lug 28 of the release lever 14 is positively gripped by a locking recess 29 of the locking lever and locks it mechanically (FIG. 6) .
  • the second lever arm 30 of the locking lever 25 projects into the path of the tap attachment 21. If the trigger is now actuated and the control lever 10 is pivoted, the locking lever 25 is also forced to move with the control lever 10 and the lock is released in time for the release of the release lever 14 (FIG. 7). Since the lever arm 30 also comes out of the path of the hammer projection 21 with this pivoting movement, the shot is fired properly. Releasing the trigger brings the control lever 10 back into the starting position and the catch consisting of the locking lug 28 and the locking recess 29 is locked again. However, the pivoting back cock 4 can now briefly open the locking mechanism by pushing the locking lever 25 against the force of the locking spring 26 (dash-dotted representation in FIG. 6) by its sliding surface 31 assigned to the lever arm 30 during its tensioning movement in order to release the trigger lever despite the securing means 24 14 move to the side and then swivel until locked by the fire lever 6.
