Definitions

  • the invention relates to a trigger device for a handgun according to the preamble of claim 1.
  • Such a take-off device is known from DE 103 05 682 B3 known.
  • the trigger rod connected to the trigger is displaced via a closure actuated by the closure control from an engagement position for tensioning a hammer in a release position to release the cocked firing lever.
  • the control is a displaceable by the movement of the closure when repeating the handgun spool by which the trigger bar is brought after triggering the first shot from its release position into a catching position for catching the taut when repeating hammer.
  • the hammer can already be caught again and held over the trigger before it reaches its fully relaxed front home position.
  • this extraction device thus essentially corresponds to that of a double action only - trigger system with the possibility of a shortened withdrawal path, in which case the reduced withdrawal path is available only from the second shot available.
  • the object of the invention is to provide a trigger device of the type mentioned, which allows a shortened withdrawal path already at the first shot.
  • the trigger device there is disposed on the hammer a cam engaged with the trigger lever, by which the trigger in a partially biased position of the hammer over the trigger lever and the trigger rod cooperating therewith is held in a retracted position with a shortened discharge path.
  • a shock spring counteracting compression spring is arranged on the hammer.
  • the compression spring is clamped in a structurally expedient embodiment between the hammer and a rotatably mounted within the percussion lever spring abutment.
  • the spring abutment is expediently arranged rotatably together with the hammer on a hammer axis. In a particularly space-saving manner, the spring abutment is housed within a slot of the hammer.
  • the trigger device according to the invention is also ready for ignition failures in which the hammer is not biased by the returning shutter, ready for use.
  • the provided on the hammer cam engages in a recess of the release lever and holds the trigger on the trigger rod and the trigger lever in a forward position, from which the trigger can be operated with, however, then longer Abzugweg and higher trigger weight.
  • trigger device of a handgun contains a hammer 1, a sear 2, a trigger 3, a trigger 4 and a hinged thereto trigger bar 5, on the impact of the hammer 1 during the actuation of the trigger 4 initially against the force of a striker 6 tensioned and then released to trigger a shot becomes.
  • the percussion spring 6 of the hammer 1 is applied in the strike direction for actuating a firing pin, not shown.
  • the force of the striking spring 6 is transmitted in a conventional manner via a Schlagfcdcfstange 7 on the hammer 1.
  • a trigger rod spring also not shown, the trigger bar is pushed backwards and upwards.
  • the hammer 1 is rotatably mounted within a fitting or handle 8 of the handgun on a hammer axis 9. How special from the Figures 2 . 4 and 6 it can be seen, within the percussion lever 1, a spring abutment 10 is also rotatably mounted on the hammer axis 9. Between the rotatable spring abutment 10 and the hammer 1, a compression spring 11 is clamped, counteracts the spring force on the hammer 1 of the force of the striking spring 6. Within the built-in or Griffstlicks 8 also cooperating with the hammer 1 catch 2 is rotatably mounted on a transverse pin 12. On the cross pin 12 also cooperating with the sear 2 release lever 3 is rotatably arranged.
  • FIG. 7 enlarged illustrated sear 2 has at the top a transverse bore 13 for the cross pin 12 and at the bottom of a catch catch 14 for engagement with a safety catch 15 on the front of the in FIG. 8 enlarged shown hammer 1 on.
  • squeezing pawl 2 at the front further includes a groove 16 in which a leg spring, not shown here for biasing the sear 2 is housed.
  • the sear 2 also includes a laterally projecting driver 17, with the in FIG. 9 shown enlarged release lever 3 cooperates.
  • FIG. 8 in two different perspectives magnified hammer 1 includes a continuous transverse bore 18 for the beat lever axis 9, around which the hammer 1 is rotatably mounted. Below the transverse bore 18, a hole 19 is provided for serving as a plant for the striker rod 7 pin. At the bottom, the hammer 1 has a groove designed as a fire stop 20 for engaging a trigger bar catch 21 at the in FIG. 10 shown trigger bar 5.
  • the safety catch 15 is provided from its front side in the longitudinal direction of the handgun inwardly extending blind hole 22 for the rear end of the compression spring 11.
  • At the front of the hammer 1 is also a slot 23 for receiving the in FIG.
  • the release lever 3 is shown enlarged. It contains an upper hole 27 for the transverse pin 12, on which the release lever 3 is rotatably mounted. Below the hole 27, a slot 28 is provided for receiving the hammer axis 9. At the back of the trigger lever 3, a nose 29 and a recess 30 for engagement with the lateral cam 26 of the hammer 1 is provided below the hole 27. At the bottom of the release lever 3 is a downwardly projecting leg 31 and a groove 32 for engagement of the trigger rod catch 21st
  • trigger rod 5 has at its inwardly cranked front end a rightwardly inwardly projecting pin 33 for connection to the trigger 4.
  • the trigger bar 5 includes a rearwardly projecting web 34 with an obliquely upwardly extending control surface 35 and a right in the direction of the percussion lever inwardly bent portion 36 with the trigger rod catch 21st
  • FIG. 11 is arranged within the striking piece 1 spring abutment 10 is shown enlarged. It contains a bore 37 for the beat lever axis 9, on which the spring abutment 10 is rotatably arranged together with the hammer 1.
  • a spring abutment detent 38 which engages with the catch catch 14 of the sear 2.
  • the spring abutment 10 has a rearwardly facing abutment surface 39 with a retaining pin 40 for the front end of the compression spring 11.
  • the cam located on the hammer 1 26 presses the lower leg 31 of the release lever 3 via the nose 29 and the release lever 3 in connection with trigger line 5 forward in the direction of the trigger 4, while keeping the trigger 4 in a position in the trigger device can be operated with a shortened withdrawal path.
  • the trigger rod 5 moves according to FIG. 3 forward, whereby the release lever 3 is rotated over the trigger rod catch 21 and the hammer 1 is further tensioned against the force of the hammer lever spring 6, while held by the sear 2 spring abutment 10 according to FIG. 4 remains in its position.
  • the prestressed compression spring 11 acts while the rising spring force in FIG. 1 shown shock spring 6 and thereby reduces the trigger weight.
  • the compression spring 11 relaxes until the lower stop surface 25 of the spring abutment 10 strikes the abutment surface 24 of the impact lever 1.
  • the trigger bar 5 is moved over the voltage applied to the beat lever axis 9 control surface 35 of the trigger rod 5 down to a position in which the trigger rod catch 21 out of engagement with the associated fire stop 20 of the hammer 1 passes and thus the hammer 1 for triggering a shot releases.
  • the sear 2 is controlled via the release lever 3 from the safety catch 15 of the hammer 1.
  • FIGS. 5 and 6 the extraction device described above is shown in a position after a Zündersager.
  • the hammer 1 and the spring abutment 10 are not held by the sear 2, since the shutter, not shown, has performed no Repetierbewcgung.
  • the compression spring 11 according to FIG. 6 relaxed.
  • the cam 26 engages the hammer 1 in this position in the recess 30 of the release lever 3 and holds the trigger 4 on the trigger rod 5 and the trigger lever 3 in a forward position with a long withdrawal path.
  • the trigger rod catch 21 in the fire door 20 of the hammer 1 is also in this position, so that the Abzugsvorrichrung can be operated with but then longer withdrawal path and increased deduction weight.
