Definitions

  • the technical field of the present invention is that of devices used for launching projectiles having no lethal effect on humans, that is to say causing no injury.
  • Aerosol bombs and tear gas grenades or projectiles Aerosol bombs and tear gas grenades or projectiles. Aerosol cans have an effective distance of a few meters and are not without risk for the user. Grenades that can be used at a much greater distance can cause impact injuries as a result of their launch with low accuracy. The energies brought into play at impact can lead with these projectiles to very serious lesions on the individual to be controlled.
  • the object of the present invention is to propose a device for launching a projectile having no impact on a target but releasing an incapacitating product at a distance and in the direction of the target.
  • Patent WO 95/15476 describes a method of neutralizing people which implements a weapon sending towards a target a projectile containing an incapacitating substance.
  • the projectile releases this substance at a certain distance from the target.
  • the release is controlled after measuring the distance at which the target is located by means (for example optical) which send a trigger signal to the projectile.
  • the trigger signal can result from braking the projectile by means of a wire connected to the weapon.
  • the subject of the invention is therefore a device for launching a non-lethal projectile, comprising a means for propelling the projectile, a linkable means which can be unwound from the launcher and connected to the projectile, a means for blocking the course of the linkage stop the stroke of the projectile, and means for calculating the distance traveled by the projectile and for controlling the locking means when the projectile (has traveled a predetermined distance, device characterized in that it comprises at least one electric coil which makes it possible to control the means for blocking the progress of the connection means and / or the activation of a pressure generator which constitutes the propulsion means.
  • the pressure generator comprises a pyrotechnic composition which is initiated following the displacement of a mobile core controlled by the electric coil.
  • the pressure generator is a reserve of gas which is opened by a striker carried by a movable core whose movement is controlled by the electric coil.
  • the locking means comprises two elements, at least one of which is movable and has its movement controlled by an electric coil, the movable element acting as a vice to wedge the unrollable connecting means.
  • the two elements of the locking means are axially aligned along the axis of the launching device, one of the elements being freely traversed by the unrollable connecting means, these two elements being intended to fit one into the other to block the unfolding of the unrollable connecting means.
  • the launching device comprises a mobile plunger which constitutes both the mobile element of the locking means and the mobile core activating the pressure generator, the coil being able to control the movement of the plunger in two opposite directions.
  • the calculation and control means may include a rangefinder to measure the distance separating the launching device from a target, a sensor to calculate the length of the unwinding of the unrollable linkage means, a computer connected to the rangefinder and to the sensor to transmit a signal for controlling the blocking means when the projectile is at a predetermined distance from the target.
  • the senor may be sensitive to markings carried on the unrollable connecting means and regularly spaced along it.
  • the markings may be of the optical or magnetic type.
  • the launching device may include an interchangeable monoblock envelope containing the projectile, the propulsion means, the locking means and the connecting means, an envelope that can be adapted into a launching tube equipped with means for calculating the stroke of the projectile.
  • An advantage of the invention lies in the absence of contact between the projectile and the target, which makes it possible to avoid any injury when the target is a human being.
  • Another advantage of the present invention resides in the release of the incapacitating products near the intended target.
  • Another advantage of the invention lies in the simplicity of the means which allow the launching and / or braking of the projectile.
  • the launching device according to the invention shown diagrammatically in FIG. 1 comprises a launcher 1 in the form of a tube incorporating all the conventional mechanisms, such as those of breech, firing or gripping of the weapon, to launch a projectile and whose representation is not necessary for the understanding of the invention.
  • the launcher 1 is notably equipped with a range finder 2 whose function is to measure the distance separating the launcher 1 from a target 3, and a sensor 4 whose function is to make it possible to calculate in real time the length of a connecting means 5 unwound from the launcher 1 and connected to a projectile 6 fired by the launcher 1.
  • the unrollable connecting means 5 is constituted by a wire 7 of the metallic or textile type, for example.
  • the wire 7 which is unwound by the projectile 6 makes it possible to stop the latter at a distance d from the target 3 and, at the time of stopping, the projectile 6 disperses the incapacitating product on the target 3 that it contains.
  • FIG. 2 illustrates in more detail the launcher 1 in which are housed in particular a means of propulsion 8 of the projectile 6, the wire 7 wound on a support, such as a coil 9, and a means 10 for blocking the unwinding of the wire 7 to stop the projectile 6 at a distance d from the target 3.
  • the reel 9 is for example rotatably mounted on an axis (not shown) carried by the launcher 1. Considering the firing direction, the reel 9 is located towards the rear of the launcher 1, while the projectile 6 is located towards the front of said launcher 1.
  • the propulsion means 8 of the projectile 6 is for example constituted by the pressure of the combustion gases produced by a propellant charge which is initiated, in a conventional manner, either electrically or mechanically by means of a striker.
  • this propulsion means 8 can be constituted by pneumatic means (compressed air or reserve of gas under pressure), by a compressed spring or any other equivalent means.
  • the means 10 for blocking the unwinding of the wire 7 to stop the travel of the projectile 6 comprises two elements, at least one of which is movable so as to act as a vice to wedge the wire 7 between them but without cutting it.
  • the two elements of the locking means 10 are axially aligned on the axis of the launcher 1, respectively formed by a counterweight 13 and a wedge 14, and mounted at a distance from one the other between the coil 9 and the projectile 6.

  • the wedge 14, mounted between the coil 9 and the counterweight 13, has a shape complementary to that of the recess 16.
  • the blocking of the unwinding of the wire 7 5 is obtained when the wedge 14 is engaged in the recess 16 either as a result displacement in translation of the wedge 14 when the counterweight 13 is fixed, or as a result of a displacement in translation of the counterweight 13 when the wedge 14 is fixed.
  • the unwinding length of the wire 7 can be calculated from the speed of the projectile 6 and, in this case, the sensor 4 is a speed sensor.
  • the length of unwinding of the wire 7 can be calculated from the signals delivered by a sensor 4 of the optical or magnetic type which detects, as the unwinding of the wire 7 , markings 17 carried by the wire 7 and regularly spaced along it.
  • the equipment of the launcher 1 is completed by electronic means 19 for calculating in real time the distance traveled by the projectile 6 and for controlling the locking means 10 when the projectile 6 has traveled a predetermined distance or is located at a predetermined distance from target 3.
  • the computer C delivers as an output a control signal from the means 10 for blocking the unwinding of the wire 7 to stop the travel of the projectile 6, when the distance separating the projectile 6 and the target 3 has reached a predetermined value d for the reasons explained in preamble.
  • this value d can be adjusted according to a range of values of the order of 10 to 25 mm, for example.
  • an incapacitating agent stored in the projectile 6 is dispersed on the target 3. Since the projectile 6 undergoes a strong deceleration when it is stopped, this energy can be used to cause the disabling agent to disperse.
  • the launcher is equipped with means making it possible to move the counterweight 13 while the wedge 14 remains fixed.
  • the counterweight 13 is movable between a front stop 20 and a rear stop 21 at the level of which its movements are damped by a spring 22.
