Definitions

  • the invention relates to a device for firing ammunition cartridges in firearms as defined in the claims, ammunition cartridges at ignition points from an ignition device synchronously are fired with functional movements of the firearm.
  • a device according to the preamble of claim 1 is well known.
  • Specially designed are designed to fire ammunition cartridges in firearms Ignition devices used. Such ignition devices are operated mechanically or electrically, such that a firing pin Ignition screw of an ammunition cartridge sticks at an ignition point.
  • a first disadvantage consists in the fact that ignition devices are actuated by electrical control Functionality of electromagnetic interference fields can be impaired are.
  • Another disadvantage is that using automatic firearms Ammunition cartridges fed via drum due to the explosion pressure be driven and that in continuous fire up to 50 shots, with sheaves with Fire cadences of 1000 rounds per minute and when the cadence changes the sheaves, for example as a result of heating the firearm body, a electrically controlled ignition device complicated and expensive is to a dessynchronization of the functional movements, in particular a striking of not yet completely at the ignition point positioned ammunition cartridges, and thus an impairment of functionality to avoid the firearm.
  • the ignition device should be extremely interference-resistant to operate Grant maximum functionality of the firearm. This task is supposed to be solvable with known and proven means and manufacturing processes. It should be of a simple, compact and robust design. Finally, should they are reliable, largely maintenance-free and have a long service life.
  • the idea of the invention is to use ammunition cartridges completely ignition device actuated by mechanical transmission means to ignite at firing points of firearms.
  • This ignition device deliberately avoids electrical and electronic components prone to failure.
  • the ignition device is fired from the explosion pressure Ammunition cartridges operated via a control slide of the firearm.
  • This Drive is positively controlled and follows inevitably synchronously changing Cadenzas of the sheaves.
  • the ignition device and the positive control can be switched on and off by a trigger.
  • FIGS. 1 to 3 show a perspective view of part of an ignition device Z of a firearm.
  • the firearm is, for example, an automatic firearm with ammunition cartridges M which are fed and controlled to position at ignition points. Any standard percussion ammunition, for example of caliber 20 to 40 mm, can be fired. Such feeding via drums and controlled positioning at ignition points is disclosed in EP-A-0 614 049 and EP-A-0 614 051.
  • the ammunition cartridge M positioned at an ignition point is used by a Impact lever 1 pierced by means of a firing pin 2.
  • the hammer 1 is positively controlled by the firearm drive.

  • the shot direction S of the ammunition cartridge M is indicated by a straight arrow.
  • the zero position is completely advanced in the direction of the advance V.
  • Control spool 3 and control shaft 4 of the device marked (see Figures 1 and 2).
  • the control slide 3 moves for example on a (not shown) guide rail in the flow V and in the return R. In the zero position the device is fully advanced. This forward and backward movement is, for example, by a (not shown) groove in the guide rail headed safely. Driven by the explosion pressure Control slide 3 along such a guide rail.
  • the control spool 3 actuates the drum and beats in the return R via the control rod 4 Control surface 5.2 of the control cam 5 and hits a control surface in the lead V. 5.1 of the control cam 5.
  • the exact position of the cam stroke is about the removal of the at least one control grooves 4.1.4.2 the zero position of the device is adjustable, i.e. via the position of the control grooves 4.1.4.2 on the control rod 4 with respect to a zero position of the device. He follows for example, the cam stroke too early, i.e. the cam is struck if an ammunition cartridge M is not yet completely at an ignition point is positioned, this synchronization of the ignition with the functional movements of the firearm by shortening the distance the control grooves 4.1.4.2 to zero the device are eliminated.
  • the firearm is in the position of the automatic firearm according to FIG in zero position with an ammunition cartridge positioned at the ignition point M loaded, the control cam 5 and the rocker arm 7 are in a downward position B, a trigger 10 blocks a cocked Clamping means 9 in a position D.
  • the trigger 10 is from the plane of the Tension-relaxation movement of the tensioning means 9 rotated away so that the tensioning means 9 is unblocked and relaxes in position C, the ammunition round is ignited. Due to the explosion pressure, the return R of the spool 3 started.
  • a control groove 4.2 of the control shaft 4 makes contact in one Return control position with a control surface 5.2 of the control cam 5 and strikes this in an upward position A.
  • the control groove 4.2 is as elongated recess in the control shaft 4 attached. By one or more elongated recesses on the control shaft 4, the control cam 5 in held this position.
  • the spool 3 runs in advance V.
  • a forward control position contacts a control groove 4.1 of the control shaft 4 a control surface 5.1 of the control cam 5 and strikes it in a downward direction standing position B, the clamping means 9 is stretched into a position D.
  • the Control groove 4.1 is provided as an elongated recess in the control shaft 4. Through one or more elongated recesses on the control shaft 4 the control cam 5 held in this position.
  • the functioning of the other transmission means can be as follows describe.
  • the rocker arm 7 contacts in position B with a clamping lever 8.
  • This contacting is advantageously carried out by a recess 7.1 of the rocker arm 7 and a counterpart at the end of the clamping lever 8 out operated.
  • This tilt mechanism around a tilt axis 6.0 is a proven one and robust mechanism.
  • the clamping lever 8 acts in one Clamping / relaxation level on a clamping device 9.
  • the clamping lever works 8 as a lever on the clamping means 9.
  • the tensioning means 9 In a position B of the ignition device Z the tensioning means 9 is tensioned in a position D, in a Position A, the tensioning means 9 is relaxed in a position C.
