Definitions

  • the invention relates to a trigger device for firing machine guns, with an actuator acting on the trigger of a cannon, driven by an actuator and movable from a rest position against the action of a restoring force into a firing position actuating the trigger.
  • Machine guns are weapons designed for continuous fire that fire automatically as long as the trigger is pressed.
  • triggering devices which are arranged on the cradle of the gun and the actual trigger of the weapon placed on the cradle, to be able to catch the return, lift longitudinally on an actuator and thereby trigger the firing sequence.
  • the actuator is in drive connection with an actuator, for example a hydraulic cylinder, an electromagnet, a spindle drive or the like, and is pushed up from a rest position into a firing position actuating the trigger to trigger the weapons. Switching the actuator off or on again brings the actuator back into the rest position due to a restoring force suitably caused by a spring or weight load, and the trigger that is no longer acted upon ends the firing sequence.
  • the invention is therefore based on the object to remedy these deficiencies and to provide a triggering device of the type described, which allows reliable shooting of single and continuous fire under constant firing conditions with comparatively little construction and space requirements.
  • the drive connection between the actuator and the actuator comprises a clutch which can be disengaged by means of an optionally usable end stop when an actuating path corresponding to the movement of the actuator is reached from the rest position to the firing position. Without using the end stop, the clutch remains closed and there is always an upright drive connection between the actuator and the actuator, regardless of the actuating movement of the actuator, so that the triggering device is suitable in the usual mode of operation for shooting continuous fire and more or less long bursts of fire.
  • the end stop becomes an on brought set, this end stop opens the clutch at the moment when the actuator has reached the firing position and actuated the trigger, whereby a shot breaks and at the same time the actuator is thrown back into the rest position by the restoring force by interrupting the drive connection between the actuator and the actuator and shooting is stopped again.
  • the trigger can therefore only be operated via the actuator until exactly one shot has been fired, and regardless of whether the shooter responds quickly or slowly or the actuator is switched off or over, automatic firing after the first shot is impossible .
  • the trigger device can be switched easily and reliably from continuous fire to single fire and vice versa, without having to redesign the whole weapon.
  • the drive connection between the actuator and the actuator can be made in and of itself in any way and can also be provided with any suitable coupling which interrupts the drive connection at the desired moment. According to an advantageous embodiment of the invention, however, there is a particularly expedient construction in the case of triggering devices having an actuator which can be raised and lowered and which forms a starting ramp for actuating the actuator and is connected to the actuator via a connecting lug or the like. Like.
  • a coupling pin engages in an elongated hole of the slide which is adapted to the course and length of the travel and a pawl assigned to the coupling pin as a coupling is pivotally mounted on the slide about an axis transverse to the direction of adjustment
  • the pawl locking in the closed position for unlocking the coupling bolt can be pivoted up against the force of a closing spring via an actuating lever projecting into the area of the end stop used.
  • the slide is moved so far over the actuator that the Starting ramp which, for example, raises the actuator, which is guided via a parallelogram link, and presses it against the trigger.
  • the slide is pushed back into the starting position by the weight of the actuator and the force of the return spring acting on the trigger, so that the desired stroke movement of the actuator is created by the reciprocating movement of the slide.
  • the coupling bolt locked within the slot with the slide brings a fixed connection between the slide and the connecting plate or actuator, and the triggering device is prepared for continuous fire without the use of the end stop.
  • the end stop is used, ie if it is brought into the path of the actuating lever of the pawl, then this end stop opens the pawl when it meets the actuating lever and releases the coupling bolt in the slot.
  • the pawl opened at this moment and the drive connection between the actuator and the actuator released thereby prevent a further sequence of shots. Because of the displaceability of the slider relative to the actuator given by the open latch, the restoring force can push the actuator together with the slider back into the rest position immediately after the first shot has been fired, this mobility being independent of the respective one due to the unlocked coupling bolt and its play in the slot The position and loading of the actuator is created.
  • a renewed firing of the weapon then requires a locking of the coupling bolt again by appropriately loading the actuator and moving the coupling bolt and spring-loaded pawl in the closing direction, so that after this independent coupling the drive connection is closed again and, depending on the choice and use of the end stop, the next single shot or Continuous fire can be shot.
  • the end stop sits on a swivel arm or the like, preferably connected with a handle bar, so that with a small swivel movement the end stop into or out of the path of the actuating lever can be brought and is therefore in or out of function.
  • a cannon 2 which is only indicated, is placed in a longitudinally movable manner and is fired by a trigger 3, the duration of the trigger actuation also automatically determining the length of the firing sequence.
  • a trigger device 4 is provided on the cradle 1, which has an actuator 6, which acts on the trigger 3 and can be moved via an actuator 5.
  • the actuator 6 is guided on a cradle-fixed holder 7 by means of parallelogram links 8, whereby it can be raised and lowered a drive-connected to the actuator 5, longitudinally guided in the holder 7 9 forms a cooperating with the parallelogram 8 ramp ramp 10 for raising and lowering the actuator 6.
  • a fork-shaped connecting lug 11 articulated on the actuator 5 is used, which engages with a coupling bolt l2 in an elongated hole l3 of the slide 9.
  • a pawl 14 which is pivotally mounted on the actuator-side end of the slide 9 about a transverse axis acts as a coupling for the coupling bolt 12 and locks it in the closed position (FIG. 1).
  • the pawl l4 has an actuating lever l5, which via an end stop l6 against the force of a closing spring l7 at the end of which to trigger a Shot required adjustment movement pivots the pawl l4 and unlocked the coupling bolt l2.
  • the end stop l6 is rotatably arranged on a swivel arm l8 via a handle bar l9 and can be swiveled in and out of the area of the actuating lever l5.
  • the end stop l6 is swung out and has no function.
  • the corresponding actuated actuator 5 pulls the slide 9 and the coupling bolt l2 locked in the slot l3 by the pawl l4 in the elongated hole l3, the slide 9 with its starting ramp l0 against the parallelogram link 8, as a result of which the parallelogram link 8 which lifts up raises the actuator 6 from its rest position into the firing position, which actuates the trigger 3.
  • the end stop l6 now only has to be pivoted into the path of the actuating lever l5 via the handle bar l9 and continuous firing is no longer possible. Because of the end stop l6, the pawl l4 is opened when the slide 9 is retracted to fire a shot as soon as the actuator 6 has reached the firing position, since the end stop l6 is adapted in its position to this travel path and is unlocked at the moment of the first firing the pawl l4 the coupling bolt l2 (Fig. 2).
  • the spring-loaded trigger 3 can push the actuator 6 back into the rest position, since the unlocked coupling bolt l2 causes a relative movement between slide 9 and connecting plate ll to the extent of the elongated hole l3 and the slide 9 can also be pushed back into the starting position due to the action of the starting ramp l0 when the actuator 6 is moved downward, without being prevented by the actuator 5 or the connecting plate 11 (dash-dotted representation in FIG. 2).
