Definitions

  • the invention relates to a number of shot limiters for automatic firearms with cock firing, in particular handguns, with a ratchet wheel, which is rotated by a tooth in each shot by a pawl, the movement of which is derived from the movement of the cock, and held in its respective position by a spring-loaded pawl is and which is provided with a control cam which actuates a member interrupting the firing sequence after a predetermined number of switching steps.
  • Such a shot number limiter is from the DE-PS 21 36 101 known.
  • the actuation of the switching pawl takes place by means of a rod articulated to the cock, on which a helical compression spring loading the cock is arranged and which, with its end penetrating an abutment for the spring, in each case towards the end of the tensioning movement of the cock against an arm of the switching pawl bumps and thereby pivots the pawl, which takes the ratchet wheel with it when it pivots.
  • the invention is therefore based on the object, so a shot number limiter of the type mentioned form that its stress is reduced and its operational safety is increased.
  • the pawl is in fixed gear connection with the tap and transmits essentially the entire, one-way movement of the tap on the ratchet wheel.
  • the pawl takes the ratchet wheel with the stroke movement of the tap.
  • the striking movement of the cock takes place under the influence of the striking spring loading the cock and is therefore solely due to the design of the weapon, unlike the cocking process taking place under the influence of the breech return, which depends to a large extent on the type of ammunition fired.
  • the stroke movement of the tap it is possible to constructively match the switching operation of the shot number limiter to the sequence of the tap movement, which leads to an optimal function of the shot number limiter.
  • the use of the blow movement of the cock is also favorable for the interruption of the shot sequence, because after the shot number limiter has been advanced, the entire return time of the breech is available in order to prepare the limbs controlled by the ratchet wheel to interrupt the shot sequence for catching the cocked cock.
  • the entire, unidirectional movement of the tap for advancing the ratchet wheel can be utilized in a simple manner in that the pawl is pivotally mounted directly on a bearing which is arranged eccentrically on the tap to its pivot axis.
  • the size and timing of the switching movement carried out by the switching pawl can be optimally coordinated with the tap movement by the arrangement of this bearing.
  • additional intermediate elements are avoided in this way, which complicate the movement sequences and increase the masses to be moved.
  • the eccentric bearing can have a relatively large diameter, so that the forces occurring during the switching process can be absorbed over a large area.
  • a particularly simple and space-saving design of such a shot number limiter can be achieved in that the pawl and the ratchet wheel are loaded by a common helical compression spring which is between two on the pawl and the pawl Rad attached, approximately parallel arms arranged and strives to keep the pawl in engagement with the ratchet wheel and at the same time return the ratchet wheel to its rest position.
  • the helical compression spring can be arranged on a spring rod articulated on the arm of the ratchet wheel and penetrating a recess in the arm of the ratchet.
  • the above-mentioned, relatively slow speed of the movement processes also allows the interruption of the shot to be effected in a particularly simple and particularly reliable manner at the same time, without having to make substantial interventions in a known trigger system which can be converted to single and continuous fire and one with which Hahn cooperating trigger lever which is pivotally mounted on the same axis as the trigger.
  • the known shot limiters mentioned above also interact with such a trigger system, but require major interventions and in particular the attachment of additional catches.
  • the ratchet wheel interrupts the firing sequence only with a trigger pawl pivotally mounted in the trigger, which supports the trigger lever pivotally mounted on the same axis as the trigger, and pulls this trigger pawl from the trigger lever, so that the trigger is released to drop into the tap stop provided for this purpose. Accordingly, there is no need to provide an additional link which holds the tap after the interruption of the firing sequence and must be triggered by the trigger device, but the trigger lever which is present anyway is also used to interrupt the firing sequence.
  • the release pawl takes the place of a fixed stop for the trigger that was previously provided in the trigger.
  • the trigger device shown in the drawing comprises a cock 2 mounted on a shaft 1 in a trigger box 4, which is loaded by a helical compression spring 3, which is supported on the one hand on a wall of the trigger box 4 and on the other hand on the head 5 of a pressure fork 6, which in turn by means of a thrust bearing 7 with the tap? connected is.
  • the cock After cocking the cock 2 by means of the firearm breech, not shown, the cock is first supported by a catch pawl 10 which engages with a catch 9 on the cock 2 with an arm 9. If the closure assumes the closed position, the catch pawl 10 is deflected in the direction of the arrow F, so that the arm 9 of the catch pawl 10 releases the catch 8 of the tap, as shown in FIG. 1.
  • the tap 2 is then held in the clamping position by a trigger lever 12, which also engages with its arm 15 in a catch 11 on the tap 2, as can also be seen in FIG. 1.
  • the trigger lever 12 is mounted in the trigger box 4 on the same shaft 14 as the trigger 16.
  • the trigger lever 12 has an elongated hole for mounting on the shaft 14 and is supported on the bearing shaft 14 with the elongated hole half 13 facing the tap 2 when the Trigger lever 12 is engaged with the tap 2.
  • a spring-loaded bolt 17 is arranged, which strives to move the trigger lever 12 in its longitudinal direction relative to the shaft 14 such that the trigger lever 12 comes with its slot 2 facing away from the tap 2 on the shaft 14 to the system 14 .
  • the trigger lever 12 is pressed on its arm 15 facing the tap 2 by a spring-loaded roller 33 in the direction of the tap 2 and is held in engagement with the catch 11 of the tap 2 when the trigger is not actuated.
  • the trigger 16 mounted on the shaft 14 is loaded clockwise by a spring, not shown, so that the trigger 16 in its rest position rests with an arm 19 on a stop pin 20.
  • the trigger 16 has a nose 21 which has a cam surface 22 cooperates on the safety shaft 23 rotatably mounted in the trigger box 4.
  • a release pawl 26 is rotatably mounted on a bolt 25 and is loaded counterclockwise by a spring 27. In its rest position, the release pawl 26 is supported with an arm 28 on a stop 31 attached in the trigger 16.
  • the weapon is secured in the position of the safety shaft 23 shown in FIG. 1.
  • the arm 21 of the trigger 16 rests on the outside of the curved surface 22 and can therefore not be deflected from the position shown. Therefore, the trigger 12 can not be deflected from the detent 11 on the tap 2, so that the tap is held securely in the position shown in Fig. 1.
  • the curved surface 22 can be deflected more or less far from the area of the arm 21 of the trigger 16, thereby setting the trigger device to single or continuous fire.
  • the position "three shot" which is shown in FIGS. 2 to 4 and in which the trigger 16 can be deflected so far that it has its arm 19 on a stop attached in the trigger box 4 36 comes to the plant.
  • the trigger lever 12 is taken along by the trigger pawl 26 when the trigger 16 is pivoted, which comes into contact with the arm 34 of the trigger lever 12 with its nose 29.
  • the spring-loaded element moves Bolt 17 the trigger lever 12 relative to the shaft 14 and thus relative to the trigger 16 with the release pawl 26, so that the lever arm 34 slips off the nose 29 of the release pawl 26 and comes to rest on the shoulder 30 of the release pawl.
  • the trigger lever 12 executes a clockwise rotation, which brings its arm 15 back into engagement with the catch 11 of the tap 2 when the pivoting angle of the trigger 16 is limited by the cam surface 22 in a manner not shown when set to individual fire.
  • the shot number limiter shown in FIGS. 2 to 5 now comes into effect, which comprises a ratchet wheel 39 rotatably mounted in the trigger box 4 by means of a hollow hub 48 concentrically with the securing shaft 23.
  • This ratchet wheel 39 interacts with a ratchet pawl 38 which is arranged on a bearing 37 attached to the cock 2 eccentrically to the shaft 1.
  • the eccentricity of the bearing 37 is dimensioned such that the pawl wheel 39 is pivoted about one of its teeth 41 with each ignition movement of the tap 2 via a switching tooth 40 attached to the switching pawl 38.
  • the pawl 38 is provided with a laterally projecting arm 42 which extends essentially parallel to an arm 45 of the ratchet wheel 39.
  • a compression spring 44 is arranged on a spring rod 43 between these two arms 42 and 45.
  • the spring rod 43 is pivotally suspended at one end on the arm 45 of the ratchet wheel 39 and at the other end of the arm 42 of the switch jack 38 slidably mounted.
  • the compression spring 44 exerts such torques on the arms of the pawl 38 or the ratchet wheel 39 that on the one hand the pawl 38 strives to engage with its switching tooth 40 between the teeth 41 of the ratchet wheel, while on the other hand the ratchet wheel 39 strives to rotate in Execute clockwise.
  • a pawl 46 also interacts, which is also pivotally mounted in the trigger box 4 on a shaft 61 and is loaded by a spring 62 which tends to engage the tooth 47 of the pawl 46 with the teeth 41 of the ratchet wheel 39 hold.
  • the ratchet wheel 39 by one Tooth advanced.
  • the indexing movement takes place over the entire stroke movement of the valve and takes place only under the precisely defined influence of the helical compression spring loading the valve.
  • the ratchet wheel is therefore advanced relatively slowly and evenly, so that a correct advancement of the ratchet wheel is ensured with every shot.
  • a nose 49 attached to the hollow hub 48 of the ratchet wheel 39 comes in with a lateral stop 70 on the release pawl 26 4 engages and pivots, the release pawl 26 so far that the release pawl 26 is pulled out with its shoulder 30 under the arm 34 of the trigger lever 12 and thereby the trigger lever 12 under the action of the spring-loaded roller 33 clockwise again is pivoted that his arm 15 comes into engagement with the nose 11 of the tap 2 when, after the shot has been triggered, the tap 2 is tensioned by the return closure.
  • the pawl 38 engages with its edge 63 in a recess provided for this purpose in the securing shaft 23.
  • the fuse is shaft rotated so far that the pawl 38 rests with its edge 63 on the circumference of the securing shaft and is thereby kept out of engagement with the ratchet wheel 39. Therefore, the number of rounds is not effective in continuous fire, and the sequence of shots is only interrupted by releasing the trigger 16.
  • the invention is not limited to the exemplary embodiment shown, but deviations from it are possible without leaving the scope of the invention.
  • a type of crank drive can be used to drive the pawl, and the pawl and the switching wheel can be loaded by means of springs which are independent of one another.
  • the advancement of the ratchet wheel could also be derived from the cocking movement.
  • the interruption of the firing sequence could take place by means of links other than the trigger pawl arranged in the trigger.
  • the illustrated embodiment represents an optimum with regard to the simplicity of the structure, the small space requirement and the reliability.
