Definitions

  • the invention relates to a device for firing ammunition cartridges in firearms, as defined in the patent claims, wherein ammunition cartridges are ignited at firing points by an ignition device in synchronism with functional movements of the firearm.
  • Specially designed ignition devices are used to fire ammunition cartridges in firearms. Such ignition devices are actuated mechanically or electrically in such a way that a firing pin pierces the ignition screw of an ammunition cartridge at an ignition point.
  • Such ignition devices have disadvantages.
  • a first disadvantage is that electrically operable ignition devices can be impaired in their functionality by electromagnetic interference fields.
  • Another disadvantage is that automatic firearms with ammunition cartridges fed via drum are driven by the explosion pressure and that in continuous fire up to 50 rounds, in sheaves with fire rates of 1000 rounds per minute and in changes in the cadence of the sheaves, for example as a result of heating the firearm body, an electrically controlled ignition device complicated and expensive is to avoid a dessynchronization of the functional movement sequences, in particular a striking of ammunition cartridges that have not yet been completely positioned at the ignition point, and thus to impair the functionality of the firearm.
  • the ignition device should be extremely resistant to interference and provide maximum functionality of the firearm. This task should be solved with known and proven means and manufacturing processes. It should be of a simple, compact and robust design. After all, it should be reliable, largely maintenance-free and have a long service life.
  • the idea of the invention is to fire ammunition cartridges by means of an ignition device which is completely actuated by mechanical transmission means at firing points of firearms.
  • This ignition device deliberately avoids electrical and electronic components that are susceptible to faults.
  • the ignition device is operated by the explosion pressure of fired ammunition cartridges via a control slide of the firearm. This drive is positively controlled and inevitably follows synchronously changing cadences of the sheaves.
  • the ignition device and the positive control can be switched on and off by a triggering means.
  • 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 firing points.
  • Such automatic revolver cannons are operated in continuous fire of up to 50 rounds, with sheaves with fire rates of 1000 rounds per minute.
  • Any standard percussion ammunition for example of 20 to 40 mm caliber, can be refined.
  • Such feeding via drums and controlled positioning at ignition points is disclosed in the Swiss patent applications P0663CH and P0665CH.
  • the ammunition cartridge M positioned at an ignition point is pierced by a firing lever 1 by means of a firing pin 2.
  • the firing lever 1 is driven by the firearm drive.
  • the explosion pressure of ignited ammunition cartridges M, which acts on a control slide 3, is advantageously used as the drive for the firearm.
  • the ignition device Z has, as the first transmission means, a control rod 4 rigidly connected to the control slide 3, which actuates a rocker arm 7 via a control cam 5 and a control shaft 6. Furthermore, the ignition device Z has, as further transmission means, a tensioning lever 8 and a means 9 exciting the striking lever 1.
  • the transmission means act on a tensioning means 9. If the control cam 5 and the rocker arm 7 are actuated from a position B into a position A, the tensioning means 9 is relaxed into a position C, the control cam 5 and the rocker arm from a position A in actuated a position B, the clamping means 9 is tensioned in a position D.
  • the operation of the first transmission means can be described as follows.
  • the control cam 5, the control shaft 6 and the rocker arm 6 are rigidly connected to one another. These transmission means are stored and tiltable about a tilt axis 6.0.
  • the rocker arm 7 is actuated by the return R and advance V of the control rod 4 with respect to a zero position of the device.
  • the directions of the return R and the forward V are indicated by straight arrows.
  • the advance V is advantageously in the firing direction S of the ammunition cartridge M, the return R in the opposite direction.
  • the direction of fire S of the ammunition cartridge M is indicated by a straight arrow.
  • the zero position is characterized by the control spool 3 and control shaft 4 of the device which are moved completely in the direction of the advance V (see FIGS. 1 and 2).
  • the control slide 3 travels, for example, on a guide rail (not shown) in the forward flow V and in the reverse run R. In the zero position, the device is fully advanced. This forward and backward movement is guided safely, for example, by a groove (not shown) in the guide rail. Driven by the explosion pressure, the control slide 3 moves along such a guide rail.
  • the control slide 3 actuates the drum and beats a control surface 5.2 of the control cam 5 in the return R via the control rod 4 and beats a control surface 5.1 of the control cam 5 in the forward run V.
  • the exact position of the cam stop can be set by removing the at least one control grooves 4.1.4.2 with respect to the zero position of the device, that is to say 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. If, for example, the cam is fired too early, i.e. if the ammunition cartridge M is not yet fully positioned at an ignition point, this synchronization of the ignition with the functional movement sequences of the firearm can be remedied by shortening the distance of the control grooves 4.1.4.2 to zero the device become.
  • a cam strike that is too late i.e. a too late firing of the ammunition cartridge M positioned at the ignition point, which delays asynchronously delaying the removal of the empty cartridge case and starting the subsequent return R of the control slide 3, can be remedied by extending the distance of the control grooves 4.1.4.2 with respect to the zero position of the device.
  • the distance of the control grooves 4.1.4.2 with respect to the zero position of the device By adapting the distance of the control grooves 4.1.4.2 with respect to the zero position of the device, the firing of the ammunition cartridges M can be synchronized with the general functional movement sequences of the firearm.
  • the use of two control grooves 4.1.4.2 is advantageous, other technical solutions with one or more control grooves are possible for the person skilled in the art with knowledge of the invention.
  • the firearm In the position of the automatic firearm according to FIG. 1, the firearm is loaded in the zero position with an ammunition cartridge M positioned at the ignition point, the control cam 5 and the rocker arm 7 are in a downward position B, a triggering means 10 blocks a cocked clamping means 9 in one Position D.
  • the triggering means 10 is turned away from the plane of the tension-relaxation movement of the tensioning means 9, the tensioning means 9 is unblocked and relaxes in a position C, the ammunition cartridge is fired.
  • the return flow R of the control spool 3 is started by the explosion pressure.
  • a control groove 4.2 of the control shaft 4 makes contact in a return control position with a control surface 5.2 of the control cam 5 and strikes it in an upward position A.
  • the control groove 4.2 is provided as an elongated recess in the control shaft 4.
  • the control cam 5 is held in this position by one or more elongate cutouts on the control shaft 4.
  • control slide 3 runs in the forward flow V.
  • a control groove 4.1 of the control shaft 4 contacts a control surface 5.1 of the control cam 5 and strikes it in a downward position B, the tensioning means 9 is in one position D excited.
  • the control groove 4.1 is provided as an elongated recess in the control shaft 4.
  • the control cam 5 is held in this position by one or more elongate cutouts on the control shaft 4.
  • the functioning of the other transmission means can be described as follows.
  • the rocker arm 7 makes contact in position B with a tensioning lever 8.
  • This contacting is advantageously performed in a guided manner through a recess 7.1 in the rocking lever 7 and a counterpart at the end of the tensioning lever 8.
  • This tilt mechanism around a tilt axis 6.0 is a proven and robust mechanism. Knowing the present invention, the person skilled in the art has numerous other possibilities for designing such first transmission means.
  • the tensioning lever 8 acts in a tensioning / relaxation plane on a tensioning means 9.
  • the tensioning lever 8 acts as a lever on the tensioning means 9.
  • the tensioning means 9 is tensioned in a position D, in a position A it is Clamping means 9 relaxed in a position C.
  • This tensioning / relaxing in positions A and B of the tensioning means 9 is indicated by an arrow.
  • the clamping means 9 is for example a spring, other known clamping means can also be used. This tensioning takes place instantly with the cam stroke.
  • the tensioning means 9 acts immediately on the striking lever 1 and strikes the striking pin 2 in the positioned ammunition cartridge M.
  • the tensioning lever 1 can be pivoted about a pivot axis 1.0. In the embodiment according to FIGS.
  • the striking lever 1 is shaped such that it swivels counter-clockwise about the pivot axis 1.0 in a tensioning / relaxation plane when the tensioning means 9 is pressed, and at the ignition point in the plane of FIG Shot direction S strikes the firing pin 2.
  • the firing lever 1 swivels clockwise about the center of gravity 1.0 back into the starting position.
  • This pivoting movement of the striking lever 1 is characterized by a curved double-sided arrow on the pivot axis 1.0. Knowing the present invention, the person skilled in the art has numerous other possibilities for designing such further transmission means.
  • the actuation of the ignition device Z can be activated by a triggering means 10 and can be deactivated by means of this triggering means 10.
  • the triggering means 10 is designed as a trigger which can be rotated about a trigger axis 10.0.
  • This release movement of the release means 10 is identified by a curved double-sided arrow on the release axis 10.0.
  • the release means 10 can be positioned with a blocking surface 10.1 in the plane of the tensioning / relaxation movement of the tensioning means 9.
  • the blocking surface 10.1 comes to stand near the striking lever 1 and prevents its pivoting movement about the pivot axis 1.0.
  • the actuation of the trigger means 10 is controlled by known and proven means.
  • the release means 10 which is shaped as a trigger, is actuated by a trigger magnet.
  • the ignition device Z is actuated.
  • Such unlocking takes place in the described embodiment by turning the release means 10 counterclockwise around the release axis 10.0, so that the blocking surface 10.1 out of the plane of the tensioning / relaxing movement of the clamping means 9 is removed.
  • This unlocked position of the release means 10 is shown in FIGS. 2 and 3.
  • the drive of the ignition device Z is driven in the continuous fire by the explosion pressure of the fired ammunition rounds M.
  • the triggering means 10 blocks the striking lever 1 of the ignition device Z.
  • the tensioning means 9 is tensioned, but without actuating the blocked striking lever 1.
  • the ignition device Z is positively controlled and inevitably synchronous with the cadence of the sheaves, in particular it follows synchronously changing Sheaf cadences.
  • the drive of the ignition device Z can be used not only for synchronous continuous fire, but also for controlled individual fire. Starting from a loaded firearm with an ammunition cartridge M positioned at an ignition point, this ammunition cartridge M can be ignited by briefly controlled unlocking of the triggering means 10 in the controlled individual fire. Due to the subsequent explosion pressure, a further ammunition cartridge M is loaded and an ammunition cartridge M is positioned at the ignition point and the tensioning means 9 is tensioned. The subsequent controlled single fire is ignited by repeated short-term unlocking of the triggering means 10. Knowing the present invention, the person skilled in the art has numerous other possibilities for designing such triggering means and mechanisms for actuating such triggering means.
