Definitions

  • the invention relates to a control and safety device for an automatic weapon with external energy, comprising an electric, hydraulic or pneumatic motor for example, for driving moving parts ensuring the supply of the weapon with ammunition, the percussion of the ammunition and the ejection of the casings after firing the ammunition, at a rate which can be relatively high, for example of the order of several hundred rounds per minute.
  • means are provided ensuring the locking of the moving parts of the weapon during the placing of a munition, the unlocking of these moving parts being ensured automatically by firing the ammunition (by borrowing gas or by recoil of the weapon). If the ammunition does not work, the moving parts of the weapon remain blocked and a reset must be carried out to evacuate the ammunition that has not been fired and resume shooting.
  • Automatic weapons with external energy are therefore generally equipped, on the one hand, with a fire control system comprising at least one actuator and a member for stopping or blocking the moving parts of the weapon, and, on the other hand, a "long fire" security system also comprising an actuator and a stop or blocking member for the moving parts of the weapon.
  • the object of the present invention is in particular to simplify and reduce these control and safety systems.
  • It relates to an automatic weapon with external energy, in which the fire control and security systems can be combined in a single mechanism.
  • firing and security control means comprise a single actuator and a single member for blocking the moving parts of the weapon.
  • the invention therefore provides a control and safety device for an automatic weapon with external energy, comprising at least one rotor driven by a motor for bringing the ammunition to a firing station, firing the ammunition and ejecting the sockets after firing, the rotor comprising at least one stop capable of coming to bear on a movable blocking part displaceable by a detent lever between a stop position where it causes the rotor to stop and an operating position of the weapon where it moves away from the stop and allows the rotation of the rotor, a return spring constantly urging the blocking piece towards its stop position, characterized in that this blocking piece is subjected to the action of a second lever movable by control means between a rest position and an active position where it removes the blocking piece from the action of the trigger and brings it to the rotor stop position, the means of second lever control comprising on the one hand a cam driven by the rotor and passing the second lever from its rest position into its active position when bringing ammunition to the firing station and, on the other hand, means of which displacement results from
  • the fire control means comprising the trigger, and the "long-fire" safety means therefore act on the same locking part of the weapon rotor, and are combined in a single device, which reduces the congestion, the number of actuators, and the risks of malfunction of the weapon, the fact that the shooting is automatically stopped in the event of a long fire of an ammunition.
  • the trigger lever and the second lever are connected to said blocking part by a system of rods forming an articulated lever, one end of a first rod being connected to a first slide movable by the lever. trigger, the other end of the first link and one end of a second link being connected to the second lever by a common transverse axis, and the other end of the second link being connected by an articulation to said blocking piece.
  • a second slide parallel to the first cited slide, connects the blocking piece to the detent lever and to the first slide, by means of a transverse finger secured to the first slide and guided in an axial lumen of the second slide.
  • first end of the first link is connected to the first slide by a transverse finger guided in an axial lumen of the first slide.
  • the second lever is driven from its active position to its rest position by a rotating finger, moved by the recoil of the weapon when firing an ammunition.
  • the rotor is automatically stopped by the blocking piece, without the need to use an external source of energy.
  • this device comprises means for decoupling the second lever and the rotor locking piece, allowing the weapon to operate without ammunition or with inert ammunition, and means comprising for example a rocker for retaining the second lever decoupled from the blocking part.
  • a simple manual intervention on the device according to the invention therefore makes it possible to operate the weapon without ammunition or with inert ammunition, for the instruction of the personnel.
  • the weapon equipped with the device according to the invention is an automatic weapon of medium caliber with external energy, having a high rate of fire, for example of several hundred rounds per minute.
  • This weapon is equipped with a motor driving in rotation a rotor 10 and a cam 12, the rotor driving the cam and making for example two complete turns and the cam 12 only one turn per firing cycle (comprising the supply of a ammunition at the shooting station, percussion of the ammunition and ejection of the cartridge case after firing).
  • the rotor 10 carries on its periphery a stop 14 associated with a damping spring 16 housed with the base of the stop 14 in a cavity of the rotor.
  • This stop 14 is intended to come to bear on the end of a blocking part 18 which is pivotally mounted about an axis 20, parallel to the axis of the rotor 10, on a plate or a support box 22, itself mounted on a fixed part of the weapon.
  • a detent lever 24, associated with an actuator 26 such as an electromagnet for example, is pivotally mounted on the housing 22 around an axis 28 parallel to the axis 20 to engage, by means of a fork 30 , a transverse finger 32 carried by a slide 34 movable in a rectilinear guide of the housing 22.
  • a second slide 36, parallel and partially superimposed on the first slide 34, is connected by one end to the blocking piece 18, one arm 38 of which carries a crank pin or transverse finger 40 engaged in a transverse groove 42 of this end of the second slide 36.
  • the opposite end of the second slide 36 comprises an axial slot 44 in which the transverse finger 32 of the first slide 34 engages.
  • the first slide 34 itself comprises an axial slot 46 in which is engaged a transverse axis 48 for pivoting one end of a first link 50, the other end of which is articulated around a transverse axis 52 on one end of a second link 54, l the other end of this link 54 being articulated at 56 on the second slide 36.
  • a compression spring 58 acts constantly on the second slide 36, in the direction tending to hold the locking piece 18 in its position shown in FIG. 1, which is a stop position of the rotor 10.
  • the axis 52 of articulation of the links 50 and 54 is itself guided in an L-shaped groove 60 of the housing 22, comprising a first branch parallel to the slide 34 and 36 and a second perpendicular branch, extending to the opposite slides.
  • this hinge pin 52 is received in a fork 62 of a lever 64 rotatably mounted on the housing 22 around an axis 66 parallel to the above axes and cooperating at one end 68 with the cam 12.
  • a pawl tilting 70 is supported at one end on a shoulder of the periphery of the lever 64, to maintain it in the position shown in Figure 1, and cooperates at its other end with the cam 12.
  • a rotating finger 72 shown hatched on the drawing, is associated with a receding part of the weapon to rotate the lever 64 counterclockwise when a shot is fired.
  • a non-return system 74 is associated with the blocking part 18 and allows the stop 14 to be retained when the latter bounces off the blocking part 18.
  • This system 74 is mounted so as to pivot about an axis 76 parallel to the axis 20 of the blocking piece 18, and bears on this blocking piece, so as to be moved away from the path of the stop 14 when the blocking piece 18 is itself brought out of this path.
  • FIG. 2 represents the state of the device when a firing order is given.
  • the actuator 26 is then excited and rotates the trigger lever clockwise around the axis 28.
  • This rotation of the trigger lever 24 results in an upward movement of the first slide 34.
  • the lower end of the first link 50, the axis 48 of which rests on the bottom of the opening 46 of the first slide follows this movement, as indicated by the arrow in FIG. 2.
  • the upper end of this link is guided by the axis 52 in the first branch of the groove 60 of the housing 22, which is parallel to the first slide 34.
  • the angle of the two links 50 and 54 is therefore not changed, and this results in a displacement towards the top of the second slide 36, with a corresponding rotation of the locking piece 18 clockwise and compression of the return spring 58.
  • the rotation of the locking piece 18 releases the stop 14 of the rotor 10 and allows rotation of the latter er, in the direction indicated by the arrow.
  • This rotation of the rotor 10 results in the start of the supply of ammunition to the shooting station.
  • the cam 12 is also driven in rotation in the direction indicated by the arrow and comes (FIG. 3) to tilt the pawl 72 and the second lever 64 clockwise, before the firing post of the ammunition. Due to the rotation of the second lever 64 clockwise, the axis 52 of articulation of the two links 50 and 54, held by the fork of the second lever 64, is moved upward in the upper branch of the groove 60 of the housing 22.
  • the first slide 34 being always held in position by the trigger lever 24, the two links 50 and 54 approach one on the other, the axis 48 of the lower end of the first link 50 moving in the lumen 46 of the first slide 34, while the lower end of the second link 54 brings the second slide 36 down, this movement being allowed by the relative movement of the transverse finger 32 in the axial lumen 44 of the second slide 36.
  • the rotation of the rotor 10 continues until the stop 14 returns to the vicinity of the locking piece 18 (FIG. 4). During this rotation, the ammunition was brought to the firing point and struck. If it functions correctly, the start of the recoil stroke of the weapon controls the rotation of the finger 72 anti-clockwise, which results in a rotation in the same direction of the second lever 64. L axis 52 of articulation of the links is then brought back to the low position, and the link 54 moves the second slide 36 upwards, the first slide 34 still being held in the high position by the trigger lever 24. The upward movement of the second slide 36 causes the locking piece 18 to rotate clockwise, and its erasure outside the path of the stop 14 of the rotor 10. The rotation of the latter can continue, for a new cycle shooting.
  • the actuator 26 of the trigger lever is de-energized, and the trigger lever 24 no longer opposes the downward movement of the first slide 34.
  • the relaxation of the compression spring 58 makes it possible to return the slides 34 and 36 to their initial position in FIG. 1, and the blocking piece 18 in the rotor stop position 10.
  • the signal to end the shot can be given after counting the number of shots fired.
  • a detector mounted on a moving part performing one revolution per firing cycle (for example on the cam 12) makes it possible to count the number of shots fired. This number of shots is compared to a programmed number of shots and the signal to stop firing is given as soon as these numbers are equal.
  • FIG. 6 illustrates the operation of the system when a munition brought to the firing station has been struck, but has not worked.
  • the device remains in the position of FIG. 3, in which the locking piece 18 is in the position of rotor stop 10.
  • the stop 14 comes to bear on the blocking piece 18, the compression spring 16 associated with this stop absorbing the shock over a rotor travel of approximately 30 °, then expanding to bring the rotor back into position shown in FIG. 6.
  • the non-return system 74 of FIG. 1 opposes the rebound of the stop 14 on the part 18.
  • the weapon control system then cuts the excitation of the actuators.
  • the return spring 58 of the second slide 36 is relaxed and does not allow the device to be replaced in the position of FIG. 1.
  • the device must then be reset by rotating the trigger lever 24 in the direction counterclockwise, which can be done manually or mechanically, or automatically when the actuator 26 of the trigger lever 24 is double-acting.
  • the weapon control system starts a time delay corresponding to a time after which the start of the shot has a near-zero probability of occurring.
  • the double-acting actuator 26 is controlled, firstly to reset the device by rotation of the trigger lever 24 anti-clockwise, then to start shooting again, by rotation lever 24 clockwise.
  • Figure 2 allows the rotation of the rotor 10, the evacuation of the ammunition not fired, and the supply of new ammunition to the shooting station.
  • the device according to the invention also allows the weapon to operate without ammunition or with inert ammunition, for the instruction of personnel.
  • the rocker 78 is actuated to release the second lever 64 which then returns to its position in FIG. 1, for example by being returned to this position by a return spring 80 ( figure 7).
