Definitions

  • the invention relates to a trigger device with a trigger for handguns, in which a trigger lug pivotably in a housing, which locks the cocked firing pin in its one pivot position, a trigger rod which supports the trigger gun in its one pivot position and thereby holds the trigger bar in its pivot position blocking the firing pin
  • the trigger rod is arranged in its other pivot position, which releases the trigger stud, and a trigger tensioning element which can be tensioned by the trigger when it is actuated against the trigger direction, with a securing element in its securing position preventing actuation of the trigger in the trigger direction .
  • the geometry of the trigger devices of small arms is usually designed such that a force of at least 1.5 kg, preferably 2 kg, must be exerted on the trigger to trigger a shot.
  • this high trigger weight often leads to the shot getting torn, especially with less experienced shooters.
  • This is remedied by the so-called piercing devices, which is an additional device built into the trigger device, with which the trigger weight can be reduced to approximately one hundred grams. Even a very slight vibration or movement of the weapon is then sufficient to trigger a shot. Therefore it is only under certain circumstances and under
  • the object of the present invention is now to further increase the safety of such trigger devices, namely to prevent the trigger from being triggered unintentionally even when the shooter is acting against the regulations and has been there for a long time before the shot, namely when the trigger device is secured , the piercer tightens and / or, if the intended shot is not fired, forgets to relax the piercer by opening the slide.
  • the trigger gallery is loaded into its pivot position blocking the strained firing pin by a spring and is forced into its other pivot position by the untensioned firing pin, wherein in the latter pivot position it locks the set clamping piece in its untensioned pivot position that the Deduction when it is actuated against the trigger direction on the piercing clamping piece, pivots it into the clamping position and holds it in an unstable equilibrium that the securing element is a slide which is in its securing position the trigger bar locks against a release of the trigger gallery and that the trigger has a projection which engages a locking element of the locking element when the locking element is tensioned and in the securing position in such a way that the locking element is locked against displacement into the unlocked position.
  • this trigger device With this trigger device according to the invention, it is thus possible to cock the set as long as the weapon is secured, but the weapon can then no longer be unlocked, so that here too the shooter is forced to fire the intended shot only after releasing the weapon, i.e. when it is already in the firing position. If the intended shot is not fired for any reason, the safety of the gun does not automatically relax by securing the weapon, but the weapon can no longer be unlocked with it; the shooter is therefore forced to relax the trigger first when attempting to unlock the weapon again. To relax the trigger, namely the noiseless relaxation, the shooter grips the trigger between the thumb and forefinger and then slowly pulls the trigger back. A snap back of the lower trigger is intercepted by the shooter's thumb during this handling.
  • a trigger gallery 2 a trigger rod 3 and a trigger 4 are each rotatably mounted in a trigger housing 1.
  • 5 with a plunger clamping piece 5 is also rotatably mounted in the trigger housing 1.
  • a safety slide 6 is slidably mounted in the trigger housing 1.
  • the take-off lug 2 can be rotated to a limited extent about an axis 7 and is loaded into an upper position by a spring 8, which ensures its coupling with a firing pin nut 9.
  • the trigger rod 3 is rotatable about an axis 10 and is loaded by a spring-loaded pin 11 in the direction of the trigger gallery 2.
  • the trigger 4 is also rotatably mounted on said axis 10 and is urged by a spring 12 bzugsstange 3 with its contact surface 13 against the A.
  • the plunger clamping piece 5 is double-armed and has a tensioning roller 14 and an adjusting screw 15 on the arm facing the trigger 4, while a spring 16 engages the other arm.
  • the adjusting screw 15 serves to compensate for manufacturing g un g s employment of the idler pulley 14 relative to the upper arm 17 of the trigger 4.
  • the securing slide 6 comprises a lower securing position (Fi g. 1) and an upper unlocked position ( Fig.2).
  • the firing pin nut occurs 9 behind a hook 18 of the sear 2.
  • the sear 2 not avoid the pressure exerted by the S chlagbolzenmutter 9 him force, ie not pivot downwardly because it with its surface 19 against the Surface 20 of the trigger rod 3 supports.
  • the trigger gallery 2 has two cams 21 and 22, the height difference between the lower cam 21 and the upper cam 22 determining the catch entry, that is to say the degree of overlap between the support surfaces 19 and 20.
  • the end faces of the cams 21 and 22 are expedient formed parallel to the direction of movement of the safety slide 6.
  • the distance between the surface 23 of the safety slide 6 and the upper cam 22 of the trigger lug 2 must be less than the distance between the surface 23 and the lower cam 21 of the trigger lug 2; in practice, the A is b-level difference expediently between 0.2 and 0.4 mm.
  • the width of the head 24 of the trigger rod 3 must correspond to the distance between the cam 21 and the surface 23.
  • the head 24 of the trigger rod 3 should also have parallel surfaces. This enables economical manufacturing of very tight tolerances by means of simple grinding processes.
  • the trigger rod 3 is pivoted out of the support latch - the trigger stud 2 for the purpose of firing the shot by pressing the lower arm 26 of the trigger 4.
  • the geometry of the trigger support latches is designed such that a force of at least 1.5 kg, preferably 2 kg, must be exerted on the lower arm 26 of the trigger 4 in order to trigger a shot.
  • the trigger weight mentioned can be reduced to a few 100 g, in extreme cases even to 50 g and less, by means of the piercing device explained below. With such a low trigger weight, a very slight vibration or movement of the interacting parts can be sufficient to trigger a shot. For this reason, it is only permitted under certain circumstances, if special safety measures and regulations are observed, to bring about this dangerous and critical condition of the weapon.
  • this state is produced by pressing the lower arm 26 of the trigger 4, that is to say by pressing the lever 26 in the direction of the arrow in FIG. 3.
  • the trigger 4 rotates about the axis 10 so that its upper one Arm 27 counterclockwise towards the chuck. piece 5 pivots.
  • the contact surface 28 of the arm 27 then presses against the roller 14, as a result of which the arm of the clamping element 5 connected to the roller 14 is pivoted upward against the pressure of the spring 16.
  • the arm 27 of the trigger 4 is pivoted so far in the direction of the chuck 5, until its edge 29 engages under the roller 14 and a balance of forces between the force of the spring 16, the force of the spring 12 and the frictional force of the moving parts arises; this position can be called the dead center position. In this position, the engraver is cocked. In order to be able to carry out this effective tensioning of the piercer, however, it is a prerequisite that - as drawn in FIG. 3 - the safety slide 6 is in the unlocked state, as will be explained later.
  • the reduction ratio and thus the trigger weight can be varied in a simple manner by means of an adjusting screw 30, with which the amount by which the arm 27 with its edge 29 can be pivoted behind the actual dead center position of the roller 14 can be determined. If the balance of forces is destroyed by a force acting on the lever arm 26 of the trigger 4 in the direction of the arrow (FIG. 4), then breaks it suddenly together under the action of the strong spring 16. The spring 16 now presses the pretensioner piece 5 back into its rest position (FIG. 1), the roller 14 throwing the arm 27 of the trigger 4 forward over the inclined surface 28 in the direction of the trigger rod 3. The arm 27 strikes with its surface 13 against the trigger rod 3 and knocks it out of the support latch 19 of the trigger gallery 2. The trigger gallery 2 thus pivots, as already described for the case of the stab-free firing, under the influence of the firing pin and releases the firing pin free.
  • the cam 32 of the trigger 4 has a recess 40 in its lower front region such that a projection 41 results above this recess 40.
  • the safety slide 6 is provided with a locking pin 60 which is slidably guided - and secured against falling out - in a blind hole of the slide 6 and is loaded by a spring 61 in the outward direction.
  • the hood 4 in its normal position, wherein the engraver is therefore not excited, then there is the protrusion 41 outside the movement path of the S perrbolzens'60, the slider 6 so unaffected by the projection 41 upward and can be moved downwardly .
  • the weapon can techer in the usual manner in a relaxed S by displacing the securing slide 6 secured arbitrarily and unlocked.
  • the situation changes, however, when the trigger 4 or its lever 26 is displaced against the trigger direction and the piercer is thus tensioned. If this tensioning of the stab occurs when the weapon is unlocked (FIG. 5), then the projection 41 comes to rest against the - oblique - forehead 60a of the Locking pin 60 or remains in front of it at a minimal distance.
  • a shot can be triggered by pulling the trigger 26 back.
  • the shooter does not fire a shot, but secures the weapon, i.e. moves the safety slide 6 downward, then the projection 41 slides over the surface of the front end 60a of the locking bolt 60, which is pressed slightly inwards until it finally over the edge 60b of the locking bolt, whereby it, relieved of the pressure, jumps forward again into the recess 40 of the trigger cam 32, which position is shown in FIG. 6 in broken lines.
  • the safety slide 6 moves with its edge 33 of the surface 23 over the surface 34 of the trigger rod 3 after a distance of a few tenths of a millimeter and thus prevents the trigger rod 3 from being pressed or Blow can be pivoted out of the catch 19 of the trigger gallery 2.
  • the inserted trigger device is already secured after a minimal displacement of the safety slide 6, so that after reaching the securing position, as is generally customary in the case of the repeating rifles known hitherto, the trigger can be stabbed by manual actuation of the trigger arm 26 without a shot being caused thereby is triggered.
  • the shooter preferably takes the trigger between the thumb and forefinger and then pulls the trigger back, wherein the trigger lever 26 snaps back; the piercing can be done completely silently.
  • the shooter To trigger a shot by means of the stabbing device, the shooter must first unlock the weapon and then cock the stabber. A procedure in the reverse order is not possible, because after the trigger has been tightened, the safety slide can no longer be moved from the securing position to the unlocked position. Tightening the trigger with the safety slide in the securing position is therefore a possible but ineffective process because it does not allow a shot. If the shooter has proceeded in the correct order, the gun has been unlocked first and then the trigger has been cocked, but brings - without firing the shot - The weapon again in the securing position, then takes place during the movement of the slide 6 down first securing against a shot and then locking the safety slide against a new unlocking.
  • the shooter After securing the weapon, the shooter should relax the trigger, which is done manually and can be carried out silently. However, if the shooter forgets to relax the trigger, the weapon remains in the locked state and cannot be unlocked; the shooter must therefore first relax the set before relocking the weapon again.
