Definitions

  • the present invention relates to a device for triggering the firing of a firearm, and more generally any firearm the aim of which is provided by a shooter.
  • the object of the invention is to increase the probability of hitting a target by ignoring the human factor at the start of the shot, by ensuring the launching of the shot independently of the shooter.
  • the invention provides a device for triggering the firing of a firearm equipped in particular with a barrel, a chamber, an ammunition magazine, means making it possible to pass the ammunition from the magazine into the gun chamber, a trigger handle, a firing circuit triggering the firing of an ammunition located in the gun chamber via a firing mechanism, and an electric generator, characterized in that it comprises a reference means making it possible to locate a target in a plane, a computer associated with electronic processing means making it possible to calculate an average point of aiming of the target from the data supplied by the computer and to authorize the firing, the electric generator supplying the reference means, the computer and the firing circuit.
  • the reference means consists of two gyrolasers providing the coordinates of the target in a plane perpendicular to the axis of the gun, each laser gyro comprising a mechanical reference parallel to the axis of the gun.
  • the computer, the gyrolasers and the ignition circuit are housed in the butt of the weapon.
  • the electric generator is housed in the handle of the weapon.
  • An advantage of the present invention lies in the very significant improvement in the accuracy of shooting for average shooters especially in times of conflict where tremors due to stress significantly reduce the probability of attack, that the shooting is carried out on fixed target or moving target.
  • Another advantage is the concomitant reduction in the consumption of ammunition.
  • Another advantage still lies in the fact that the operation of the weapon is always possible even in the event of a failure of the device, without any modification.
  • the shooter when the shooter triggers the shot, it is in reality the system according to the invention which will activate the start of the shot and not the shooter himself, when the aim passes in the vicinity of the theoretical average point. virtual determined by the calculator.
  • the shot is triggered if and only if the shooter returns to the vicinity of the middle point, which increases security.
  • a weapon designated by the general reference 1 comprises in a known manner a stock 2, a barrel 3 extended by a chamber 4 and having an axis 5 or firing axis.
  • the weapon 1 is also provided with a sighting support 6 delimiting a sighting axis 7 parallel to the firing axis 5.
  • It comprises a magazine 8 of ammunition 9, which is associated with a reset spring 10.
  • a member It can occupy three positions A, B and C.
  • Position A can control, for example, burst fire, and position B, single shot.
  • Position C constitutes a safety catch.
  • the weapon 1 comprises a handle 12 which integrates supply means 13 constituted by batteries or accumulators and a trigger 14 secured to an axis 15 sliding relative to a support 16 secured to the handle 12.
  • the trigger 14 is subjected to the action of a spring 17 bringing it back to its original position.
  • the axis 15 carries at its end a control circuit 18 making it possible to fix three positions for driving the trigger 14 which will be explained below.
  • a computer 19 of known type associated with processing electronics, a microcontroller and a trigger circuit.
  • the role of the computer is to process the electrical signals received according to the firing sequence provided below and to deliver a signal authorizing the shooting.
  • two gyrolasers 20 and 21 make it possible to define a reference point for the weapon.
  • the laser gyro 20 defines a direction X and includes a mechanical reference parallel to the axis 5 of the barrel.
  • the laser gyro 21 defines a direction Y and includes a mechanical reference parallel to the axis 5 of the barrel.
  • the directions X and Y are perpendicular to each other and define a plane perpendicular to the firing axis 5 of the gun.
  • the gyrolaser 20 is connected to the computer 19 by input conductors 22, and the gyrolaser 21 to the computer by input conductors 23.
  • the two gyrolasers 20 and 21 are controlled by the computer 19 using the output conductors 24.
  • the computer 19 and the gyrolasers 20 and 21 are supplied with electrical energy from the generator 13 by conductors 25.
  • the computer 19 is also connected to the trigger 14 by conductors 26a and to the control member 11 by a driver 26b.
  • the computer 19 delivers a signal which is sent via a command 27 to a firing circuit 28.
  • This circuit 28 is of the high voltage type and initiates an electrical firing mechanism for the ammunition 9.
  • the circuit 28 is an electronic assembly for converting current into high voltage current.
  • the mechanism 29 is a known element of the trade, and it provides electrical initiation of the ammunition 9 housed in the chamber 4 of the weapon.
  • the circuit 28 and the mechanism 29 are replaced by an assembly ensuring firing by percussion of the ammunition 9.
  • the command 27 is sent to a power circuit 30, supplying the winding 31a of an electromagnet 31 which actuates the ammunition 9 located in the chamber 4 by a striker 32.
  • the striker 32 for example a steel or soft iron bar, is housed inside the winding 31a. At its rear part, the striker 32 comprises a shoulder 32a on which bears a return spring 33.
  • the winding 31a is supplied with current, the magnetic field created inside the coil 31a causes the striker 32 to move, which percussion initiates the ammunition 9 housed in the chamber 4.
  • the supply current is then cut, and the striker 32 is returned to its arming position by the return spring 33.
  • the other elements of the weapon remain identical to those of the weapon shown in Figure 1.
  • the shooter takes aiming along curve 40.
  • the shooter presses the trigger tail 14 at point 41, while the real firing position intervenes at point 42
  • This possibility of shooting is obtained when the shooter presses fully on the trigger tail 14, the control member being in position A or B.
  • the shooter proceeds as described above by describing the curve 40, and by actuating the trigger tail which has, as indicated above, three insertion positions.
  • the first position authorizes the powering up of the gyrolasers 20, 21 and of the computer 19.
  • the second position authorizes the firing, and the third allows the direct firing without the aid of the device according to the invention.
  • the shooter when the shooter has taken aim and is on target, he presses the trigger 14 to reach the first insertion position mentioned above.
  • the gyrolasers 20 and 21 provide a reference, and the computer 19 records the equation of a sighting curve 43 on the target and processes this curve in real time to calculate a virtual theoretical average point 44 very close to the real center of the target .
  • the shooter starts the shot, it is actually the weapon that activates the start of the shot when the aim will pass over or near an area close to the virtual theoretical average point 44. It is quite obvious in this case that the shot is fired if and only if the shooter passes through the said area close to the average point .
  • the shooter corrects his aim and the computer triggers the shot when the target league returns to the vicinity of the mean point. If not, the shot is impossible and the release of the trigger causes the gyrolasers to be switched off and the results recorded to be canceled.
  • Mobile target shooting takes place in a slightly different scenario.
  • the shooter begins to take aim by following the target according to the real aim curve 50 and presses the trigger 14 to reach the first position.
  • the gyrolasers 20 and 21 are then activated and provide a reference in a plane perpendicular to the firing axis.
  • the shooter continues to follow the target, and the computer determines an average curve 51 by a polynomial of the fourth degree. It presses harder on the trigger to reach the second position and anticipates the trajectory of the target.
  • the computer 19 starts firing.
  • the weapon can be fitted with all modern sighting systems such as optical or infrared glasses, light amplifications, etc.
