Definitions

  • the invention relates to a trigger system for handguns according to the preamble of claim 1.
  • a trigger system for a handgun which comprises a trigger which can be rotated about a trigger axis, a striking mechanism with a striker lever which can be rotated about a trigger lever axis and a trigger rod for connecting the trigger to the striking mechanism.
  • the trigger bar is designed in the form of a rigid rail, which is bent at its front and rear ends and contains projections protruding in different directions for engagement with different detents of the striking lever.
  • Such a fume cupboard system has a relatively complex structure and is matched to a special fume cupboard characteristic. In addition, production is complex and associated with corresponding costs.
  • the object of the invention is to provide a trigger system for small arms, which is simple in construction and enables various trigger characteristics even without complex conversion measures.
  • the trigger rod arranged between the trigger of a trigger device and a striking mechanism consists of a piece of wire.
  • a trigger rod is extremely flexible compared to rigid trigger rails and ensures a pleasant trigger feeling due to its flexibility.
  • the trigger bar is also particularly light and can be manufactured easily and inexpensively.
  • the trigger rod can be bent from a single piece of wire.
  • suitable attachments can be placed or attached to the trigger rod, which is made of a wire.
  • the pull-off behavior can be changed in a relatively simple manner by a suitable choice of material or different configurations of the attachments.
  • the trigger rod is constructed symmetrically and has two parallel legs connected to one another via a connecting piece. This enables a more even and symmetrical power transmission between the trigger and the striking mechanism.
  • a winding for connecting the trigger rod to the trigger is expediently provided on each of the two legs of the trigger rod.
  • the trigger rod which is bent from a piece of wire, can be arranged on a cross pin arranged in the trigger and displaceably guided within a through opening of a receiving block.
  • the trigger rod has free end pieces projecting forward from the windings for bearing against a counter bearing.
  • the trigger rod is preferably made of spring steel wire. As a result, the trigger rod can simultaneously take on the function of a reset element for the trigger.
  • a trigger rod latch cooperating with the striking mechanism can be arranged.
  • the trigger rod catch can contain lateral depressions and a lower groove for the engagement of the trigger rod.
  • the trigger rod catch expediently has a front catch edge for engagement with a reset lever of the striking mechanism and a rear catch edge for engagement with a double-action catch of the strike lever.
  • the reset lever can be arranged on a catch pawl rotatable about a catch pawl axis by means of an adjusting screw.
  • the trigger contains a trigger base that can be rotated around the trigger axis, to which different trigger tongues can be detachably attached and replaced if necessary can.
  • the trigger base preferably interacts with a pressure piece acted upon by a compression spring.
  • the compression spring can be supported at one end on the pressure piece and at the other end on an axially adjustable adjusting screw by means of an adjusting nut. This allows the trigger resistance to be set.
  • FIG. 1 to 4 schematically illustrated trigger system of a handgun contains a trigger device 1 with a trigger 3 rotatable about a trigger axis 2, a striking mechanism 4 with a striking lever 6 rotatable about a striking lever axis 5 and a trigger rod 7 for connecting the trigger 3 to the striking mechanism 4.
  • the trigger device 1 contains a receiving block 8, in which the trigger 3 is arranged rotatably about the trigger axis 2 arranged transversely to the receiving block 8.
  • the receiving block 8 with the trigger 3 arranged therein can be detachably fastened in a handle of a handgun by means of a transverse bore 9 and a shaft of a disassembly lever, not shown, protruding through the transverse bore 9.
  • Trigger 3 designed as a single-action-only trigger contains a trigger base 10 which is arranged in the receiving block 8 and can be rotated about the trigger axis 2 and to which a trigger tongue 11 is detachably fastened by means of a trigger adapter 12.
  • the trigger adapter 12 is fastened to the trigger base 10 by means of a retaining pin 13 and can be removed if necessary.
  • the trigger tongue 11 is adjustably attached to the trigger adapter 12 via a retaining screw 15 which engages in an elongated hole 14 in the trigger adapter 12. As a result, the trigger tongue 11 can be displaced in the longitudinal direction relative to the trigger adapter 12 and locked in a desired position.
  • a through opening 16 designed as an oblique slot for guiding a transverse pin 17 arranged in the trigger base 10 for holding the trigger rod 11.
  • the cross pin 17 is seated in a recess 18 of the trigger base 10 arranged above the trigger axis 2 and is held on the trigger base 10 by means of a slide 20 preloaded by means of a compression spring 19.
  • a pressure piece 22 which is displaceable in the longitudinal direction and biased by a compression spring 21 in the direction of the trigger base 10.
  • the compression spring 21 is supported at one end on the pressure piece 22 and at the other end on an adjusting screw 24 which is axially adjustable by means of an adjusting nut 23.
  • the adjusting screw 24 which is displaceable in the receiving block 8 can be displaced in the longitudinal direction and the compression spring 21 can thus be biased against the pressure piece 22.
  • the pressure piece 22 is thus biased by the trigger base 10 against the compression spring 21, so that a higher one according to the setting of the adjusting nut 23 or less trigger resistance.
  • a trigger base set screw 26 is also arranged in a threaded bore 25 on the rear side of the receiving block 8.
  • the striking mechanism 4 contains, in addition to the striking lever 6 which can be rotated about the striking lever axis 5, a catch pawl 27 which is associated with the striking lever 6 and which can be rotated about a catching pawl axis 28.
  • the catch lever 27 is held in a cocked position by the catch pawl 27.
  • the striking mechanism 5 further includes an in Figure 1 Shock spring 29 shown, by means of which not only the striking lever 6 in the striking direction but also the catch pawl 27 in an upper catching position for engagement with an in Figure 3 recognizable fire catch 30 of the impact lever 6 is pressed.
  • the pull rod 7, which is bent from a piece of wire, preferably from spring steel wire, has two mutually parallel legs 40, each with a winding 41, a connector 42 at right angles to legs 40 at the rear end and two free end pieces 43 projecting diagonally forward from the windings 41 front end on.
  • the trigger rod 7, which is designed as a double leg spring, is arranged on the two ends of the cross pin 17 which are laterally projecting with respect to the receiving block 8 and which are held in the trigger base 10 and guided in the oblique through opening 16 of the receiving block 8.
  • the two free end pieces 43 of the trigger rod 7 projecting towards the front rest on the underside of a counter bearing 44 designed here as a transverse pin in the receiving block 8.
  • the trigger rod 7 is pushed backwards and the trigger 3 is pushed forward into its starting position.
  • a trigger rod latch 45 which interacts with the striking mechanism 5 is fastened.
  • the trigger rod catch 45 has lateral recesses 46 for engaging the two legs 40 and a lower groove 47 at the rear end for engaging the connecting piece 42.
  • FIG. 7 it is shown that 7 different attachments 53 can be plugged or placed on the pull rod 7, which is made of a wire.
  • the withdrawal behavior can be changed in a relatively simple manner by suitable choice of material or different configurations of the attachments 53. If the attachment 53 is made of metal, for example, the deflection of the trigger rod can be reduced.
  • the attachments can also be made of plastic or another suitable material.
  • 7 sleeve-shaped attachments 53 can be placed on the two legs 40 of the trigger rod. These attachments 53 can, for example, be clipped on or attached in another way to the trigger rod 7.
  • the trigger rod 7 which is designed as a double leg spring, with the trigger rod catch 45 arranged at its rear end is pulled forward in the firing direction via the transverse pin 17.
  • the trigger rod catch 45 takes the reset lever 39 with it during the forward movement via a front catch edge 48. This in turn takes the catch pawl 27 to release the fire catch 30 on the striking lever 6.
  • the trigger rod catch 45 rests on the underside of the reset lever 39.
  • the trigger 3 In order to trigger the shot again, the trigger 3 must be returned to its front starting position, so that the front locking edge 48 of the trigger rod catch 45 again behind the Reset lever 39 arrives. The path required for this can be set by means of the third adjusting screw 38.
  • the trigger tongue 11 In order to convert the trigger mechanism from the single-action-only mode described above to a single-action / double-action mode, the trigger tongue 11 only has to be dismantled together with the trigger adapter 12 and against an in Figure 5 shown double-action trigger tongue 49 are replaced.
  • This trigger tongue 49 permits an increased trigger path, so that the trigger rod catch 45 according to FIG Figure 6 can reach behind a double-action catch 51 of the relaxed striking lever 6 with a rear catch edge 50. This is possible both in the completely relaxed state of the striking lever 6 and in a state in which the striking lever 6 rests on the catch pawl 27 with a safety button 52.
  • the integrated single action mode then works as described above.
