Definitions

  • the invention relates to a trigger device for an automatic firearm according to the preamble of claim 1.
  • a known trigger device of this type see DE-A-3 103 864
  • the breech body of the firearm is provided with a catch shoulder and a control surface for interaction with this trigger device .
  • This trigger device is arranged in a housing and has a first control lever, which can be actuated by a trigger table, and a second control lever, which can be actuated by the control surface of the closure body. Furthermore, there is a catch pawl which can be pivoted into the movement path of the catch shoulder and can be actuated by these two control levers.
  • the second control lever pivotable as a release lever, is arranged on a holding lever.
  • the holding lever is mounted about an axis of rotation fixed to the housing and pivotable against the force of a holding spring.
  • a nose of the holding lever holds the catch pawl in a first clear intermediate position in a manner that can only be released by the locking body.
  • the first control lever is pivotally mounted in the housing as a trigger lever and a sub-lever for the catch is pivotably arranged on the trigger lever.
  • the catch pawl has a concave surface on the back, above a support surface interacting with the sub-lever, for deflecting contact with the sub-lever in a second intermediate position: to release the catch pawl from the first intermediate position, the holding lever can be deflected counterclockwise by the locking body via the release lever .
  • This known trigger device does essentially the same object as the present invention, namely to avoid damage to the catch surface on the locking block and the stop surface on the catch pawl. Such damage can occur if the locking block strikes the catch pawl before the catch pawl has fully reached its catch position. The locking block should only be able to be caught by hitting its catch surface with the catch surface of the catch pawl.
  • the present invention aims to provide a trigger device which does not have the disadvantages mentioned and which is much simpler in construction.
  • the trigger device according to the invention has the features mentioned in the characterizing part of claim 1, by means of which the disadvantages mentioned above are avoided.
  • the trigger device is independent of the weapon operation when releasing the catch pawl, d. H. the deduction cannot be released at an unfavorable moment. A slow release of the catch lever is also not possible because the release is controlled by the lock.
  • the trigger device according to the invention is intended for a firearm, of which only a part of a reciprocating breech block 10 is indicated in FIGS. 1 and 2.
  • this locking block 10 is in its rearmost position and is held in this position by a catch 11.
  • the locking block 10 has a stop surface 12 which bears against a catch surface 13 of the catch pawl 11. Since very large forces occur when catching the locking block 10 through the catch pawl 11 (up to six tons), it is essential that the impact surface 12 of the locking block 10 against the catch surface 13 of the catch pawl 11 collides completely in the area shown in FIG. 1 position shown is to damage the To avoid locking block 10 or the fan g jack 11.
  • the present invention aims to ensure this.
  • the catch pawl 11 is pivotally mounted about an axis 14 which is fastened transversely to the direction of movement of the locking block 10 in a housing 15 of the trigger.
  • This housing 15 is, in a manner not shown, resiliently mounted in the weapon in order to be able to resiliently absorb the impact of the locking block 10 on the catch pawl 11.
  • a strong compression spring or coil spring 16 is provided in order to hold the catch pawl 11 in the position shown in FIG. 1, a strong compression spring or coil spring 16 is provided.
  • This coil spring 16 is supported on the one hand in a recess 17 of the catch pawl 11 and on the other hand on a cup-shaped spring bearing 18.
  • This spring bearing 18 has a thread and is screwed into an opening in the housing 15.
  • the spring bearing 18 can be screwed deeper or less deep into the housing 15.
  • a pin 19 secures the spring bearing 18 against unintentional rotation.
  • the catch pawl 11 is secured in its catch position according to FIG. 1 against any unintentional pivoting by a laterally displaceable bolt 20. To trigger a shot, this bolt must first be moved.
  • a trigger lever 21 is used to actuate the catch pawl 11 and is pivotally mounted about an axis 22 which is fastened transversely to the direction of movement of the locking block 10 in the housing 15 of the trigger.
  • the trigger lever 21 has three arms 23, 24 and 25. According to FIG. 2, the arm 25 is perpendicular to the two horizontally directed arms 23 and 24.
  • the vertically directed arm 25 engages with a nose 26 in a recess 27 of the catch pawl 11 and serves for actuating this catch pawl 11.
  • the arm 23 directed to the right is supported on a trigger table 28 which is raised in a manner known per se to trigger a shot.
  • a pin 31 attached to the arm 23 serves to guide the compression spring 29 and, together with the blind bore 30, is intended to prevent the compression spring 29 from buckling.
  • the third arm 24 serves to lock the trigger lever 21 in one of its release positions shown in FIG. 2 and interacts with a locking bolt 36 described below.
  • a locking scanning lever 33 is pivotally mounted about an axis 32.
  • the axis 32 like the axes 14 and 20, is fastened transversely to the direction of movement of the locking block 10 in the trigger housing 15.
  • This scanning lever 33 has a sensing surface 34 which interacts with the underside 35 of the locking block 10, which is designed as a control surface.
  • the locking or locking bolt 36 mentioned above is slidably mounted in a bore 37 in the scanning lever 33.
  • a spring 38 is supported on the one hand on the locking bolt 36 and on the other hand on a pin 39 inserted into the bore 37 and has the endeavor to press the locking bolt 36 into its locking position shown in FIG. 2.
  • the locking bolt 36 has a head 40 which is pressed by the spring 38 against a shoulder 41 in the bore 37.
  • the arm 24 of the trigger lever 21 lies against the locking bolt 36 in the position shown.
  • the locking scanning lever 33 also has a nose 42 which interacts with a sub-lever 43.
  • the lowering lever 43 prevents the locking scanning lever 33 from pivoting clockwise.
  • a spring 44 tends to pivot the scanning lever 33 clockwise and thereby press the nose 42 of the scanning lever 33 against the sub-lever 43.
  • This spring 44 only the upper end is indicated in FIG. 2, which is supported by a bolt 46 on a stop 45 of the scanning lever 33.
  • This parking lever 43 is pivotally mounted about the axis 22 already mentioned. The end, not shown, of the spring 44 is supported in a blind bore of the trigger housing 15 in a manner not shown.
  • a spring 47 which is located in a bore 49 of the trigger housing 15, is supported at one end by a sleeve 48 on the sub-lever 43 and tends to pivot the sub-lever 43 in the counterclockwise direction and thereby against the nose 42 of the scanning lever 33 to press.
  • a trigger lever 50 which is supported on the trigger table with an arm 51, just like the trigger lever 21, is used to actuate the lowering lever 43.
  • the other arm 52 of the release lever has a stop 53 which interacts with the under-lever 43. This stop 53 can be supported on the jack lever 43 and pivot the jack lever clockwise against the force of the spring 47.
  • a spring 57 (FIG. 3), which is supported on the one hand on the housing 15 and on the other hand on the arm 51 of the release lever 50, has the endeavor to pivot the release lever 50 in a clockwise direction and thereby remove the under-lever 43 from its position according to FIG 1 position to pivot. As a result, the scanning lever 33 is released.
  • a centering bushing 55 inserted into the housing 15 is used to adjust the preload of the spring 47.
  • the trigger The lever 50 is pivoted together with the support 43 and the trigger 21 on the axis 22 mentioned.
  • the centering sleeve 55 is secured by a pin 56.
  • the closing block 10 is thrown back into its rearmost position by the force of the propellant charge. If the trigger table 28 has not yet been lowered (against the direction of arrow B), the breech block runs forward again to fire another shot or several shots until the trigger table is lowered.
  • the scanning lever 33 can thus be pivoted clockwise, as stated, whereby the locking bolt 36 releases the trigger lever 21. Together with the trigger 21, the catch pawl 11 is then released. The catch pawl 11 can thus move in the path of the locking block 10. It follows from this that the catch pawl 11 can only move into the path of the locking block 10 if the locking block 10 is not in the area of the trigger, i. H. when the underside 35, formed as a control surface, of the locking block 10 releases the scanning lever 33.
  • the scanning lever 33 thus has the task of the trigger lever 21 and the catch pawl 11 at the right moment, d. H. as stated, to release when the locking block 10 is not in the area of the trigger device.
  • the scanning lever 33 preferably has a scanning surface 34 which is formed by two planes, the right plane of which is approximately parallel to the movement path of the locking block 10 and the left plane is inclined in the opposite direction at an acute angle to this movement path (FIG. 2) to ensure a smooth impact of the locking block 10 on the scanning lever 33.
