Definitions

  • the invention relates to a trigger system for handguns according to the preamble of claim 1.
  • Such a trigger system is from the US Pat. No. 2,846,925 known.
  • This also includes a hammer, a sear assigned to the catch, a trigger and cooperating with the trigger trigger rail.
  • the percussion lever has a first catch for holding the percussion lever in a fully cocked position and a second notch for supporting the percussion lever in a partially pre-stressed position.
  • front and rear Abzugsschienenrastkanten are provided for engagement with a front and rear Schlaghebelrast of the hammer.
  • the object of the invention is to provide a trigger system of the type mentioned, which allows stripping in double action mode with a lower trigger weight and remains functional even with Zündversagern.
  • Double Action mode Compared to known Single Action / Double Action trigger systems of the hammer is partially biased at the trigger system according to the invention in Double Action mode and has in this position in addition to a favorable leverage of the engaged notches of trigger rail and hammer to beat axis. As a result, the double action mode allows for lower trigger resistance compared to conventional systems.
  • a handgun equipped with the inventive extraction system can always be carried in a partially prestressed condition without the risk of inadvertent delivery of a shot.
  • this teilvorgespannten state of the hammer is held in a partially tensioned position, in which position the impact spring force would not be enough to bring a cartridge to the ignition. From this position, however, the trigger system can be operated with a lower force compared to the conventional double action systems, since when stripping the striker spring no longer has to be stretched by the entire measure.
  • the trigger system By repeating (manual actuation of the closure or by the return due to the recoil closure after the delivery of the first shot) the trigger system enters a preloaded single action position. From this position, the trigger system can be operated with little effort, since only the locking edge of the squeeze must be pressed from the catch of the preloaded hammer.
  • the power is transmitted via trigger, trigger rail, release lever and sear.
  • FIGS. 1 to 4 In various positions schematically illustrated trigger system of a handgun contains a hammer 1 with a sear 2, a trigger 3 and a hinged with this trigger rail 4, about the impact lever 1 when operating the trigger 3 initially tensioned against the force of a striking spring, not shown, and subsequently released to trigger a shot.
  • the trigger rail 4 is acted upon via a - not shown - trigger rail spring backwards and upwards.
  • the hammer 1 is arranged about a beat lever axis 5 rotatably between two spaced-apart side parts of a handle or built-in part 6. Between the two side parts of the handle or mounting part 6, the sear 2 is rotatably mounted about a transverse pin 7. By this fishing pawl 2 of the hammer 1 is held in a teilvorgespannten position or a fully cocked position, which will be explained in more detail below.
  • the trigger 3 is arranged about a trigger axis 8 rotatably mounted on the handle or mounting part 6.
  • trigger rail 4 has at its inwardly cranked front end 11 a bore 12 for attachment to the pivot pin 10 of the trigger 3 on.
  • the trigger rail 4 includes an upwardly projecting control cam 14, a rearwardly projecting web 15 with an obliquely upwardly extending control slope 16 and a right angle in the direction of the percussion lever inwardly bent portion 17 with a first lower Discharge rail detent edge 18 and a laterally and upwardly offset second Abzugschienenrastkante 19th
  • FIG. 6 shows, the hammer 1 on its underside a cam 20 and a first lower hammer catch 21.
  • the hammer 1 further includes on its side facing the trigger rail 4 a laterally projecting second upper Schlaghebelrast 22.
  • the first hammer catch 21 is for engagement with the Abzugschienenrastkante 18.
  • the second Schlaghebelrast 22, the offset above the first hammer latch 21 and with respect to this forward While the first catch lever catch 21 is arranged on a lateral franking 35 on the side facing the trigger rail 4 side of the percussion hammer 1, the second catch lever catch 22 is located on a lateral projection 36 at the trigger rail 4 pointing side of the percussion hammer 1.
  • the second hammer catch 22 includes the hammer 1 also has a transverse bore 23 for in FIG. 1 Shock lever axis 5 shown, over which the hammer 1 between the side parts of the handle or fitting 6 is rotatably arranged.
  • an upper and lower catch 24 and 25 are provided for engagement of the sear 2.
  • Sling 2 shown separately has on its underside a catch catch 26 for engagement in the notches 24 and 25 of the hammer 1 on.
  • the sear 2 also includes a laterally projecting driver 27, which is provided with a driver 33 of an in FIG. 8 shown trigger lever 31 cooperates.
  • the sear 2 has at the front a groove 28 in which a not shown here Leg spring for biasing the sear 2 is housed.
  • further aligned holes 29 and 30 are also provided for the transverse pin 7.
  • the release lever 31 is shown, which is also arranged rotatably about the transverse pin 7.
  • the release lever 31 has a bore 32.
  • the release lever 31 in addition to the downwardly projecting driver 33 also includes an inwardly bent web 34 which cooperates with the web 14 of the trigger rail 4.
  • FIG. 1 shows the trigger system in a partially pre-stressed double action position.
  • the catch pawl 26 engages the sear 2 in the upper catch 24 of the hammer 1, whereby the hammer 1 is held in a position in which the force of the hammer spring, not shown, would not be enough to ignite a cartridge.
  • the percussion lever 1 can be actuated via the lower trigger rail detent edge 18 cooperating with the lower detent lever catch 21. Since the lower hammer catch 21 has a greater distance from the hammer axis 5 than the upper hammer catch 22, the hammer 1 can be actuated from this position with less trigger resistance.
  • the upper trigger rail latching edge 19 shown in the lower right illustration and the lower latch 25 of the firing lever 1 are not in function in the partially preloaded double action position.
  • FIG. 3 shows the trigger system in a tight single action position.
  • This position takes the trigger system by the repetition (manual retraction of the closure or retraction of the closure by recoil impulse upon the delivery of a shot).
  • the hammer 1 is held in its fully cocked position by engagement of the catch catch 26 in the lower catch 25 of the hammer 1.
  • the trigger 3 of the trigger lever 31 is pivoted by the control cam 14 of the trigger rail 4 and the web 34 of the trigger lever 31 upwards.
  • the sear 2 is rotated via the driver 33 of the release lever 31 and the associated side driver 27 on the sear 2 so that the catch catch 26 lifted from the lower catch 25 of the hammer 1 and the hammer 1 is thus released.
  • a relaxation lever not shown here, the trigger system can be controlled in a conventional manner and safely brought from the single action position in the biased double action position.
  • the trigger system described above is shown in a position after a failure to fire or a knockout with empty cartridge chamber.
  • the hammer 1 is in an unstressed front starting position. In this position, the trigger rail catching edge 19 is in engagement with the upper hammer catch 22.
  • the hammer 1 can be stretched over the trigger slide latching edge 19 and the upper catch lever catch 22 and knocked off again. Since the upper hammer catch 22 has a smaller distance from the hammer axis 5 than the lower hammer catch 21, however, an increased force is required here.
  • the trigger rail 4 is controlled via the also in function passing trigger rail locking edge 18 and the control cam 20 on the hammer 1 in a position in which the trigger rail latching edge 19 and the hammer catch 22 are no longer in operation.
