Definitions

  • the present invention relates to a safety device for a pyrotechnic chain.
  • Security devices are already known comprising a fire switch component placed in a pyrotechnic chain between the primer and the secondary detonation initiating explosives. Such devices are used in artillery projectiles or in missiles.
  • the fire switch component is a thick metallic element, the triggering of which, that is to say its separation from the pyrotechnic chain, is controlled by an external force, for example a clock system allowing to choose the time of the explosion.
  • these known safety devices comprise three main organs, namely the initiation of ignition, the switch component and the regulator system (anchor) of the clock system.
  • the axis of this regulating system must imperatively be confused with the axis of rotation of the projectile.
  • the firing initiator, the switch flap and the anchor are arranged one behind the other along the axis of rotation of the projectile. It follows that the dimensions of the safety device are important along this axis and that the length and the shape of the fire channel are disturbed by the relative position of the primer.
  • the switch flap is between the primer and the anchor or if the anchor is placed between the primer and the switch flap, the light must pass through the anchor to reach secondary explosives from the primer.
  • the connections of this primer with the outside are difficult to achieve.
  • an electrical connection by wire or pin it is necessary to pass these bodies near the regulator, while in the case of a fire transmission by fireworks upstream, the anchor and its support form a screen as troublesome as in the first mentioned provision.
  • the present invention relates to a safety device for a pyrotechnic chain which can be miniaturized to the point that its largest dimension can be lowered below 10 mm.
  • the safety device intended for the pyrotechnic chain of a rotating projectile provided with an explosive charge and comprising a movable member actuated by a clockwork mechanism with tilting regulator and capable of occupying two different positions , for the first of which the firing of said explosive charge is prevented, while for the second of said positions the ignition of this explosive charge is possible, is remarkable in that said movable member is housed in a recess of said projectile and encloses said clock mechanism, its regulator, as well as a trigger lever blocking in said first position any movement of said member relative to the projectile, but the action of which is capable of being inhibited by said clock mechanism and in that, in the first position, the axis of the tilting regulator coincides with the axis of rotation of said projectile.
  • a compact assembly is obtained whose thickness can be limited, since the movable member performs the switch functions while incorporating the control mechanism.
  • the organ itself and the whole becomes a protective element contributing to safety, while in known devices only a part of them acted as a switch.
  • the movable member is constituted by a rotor capable of rotating around an axis parallel to the axis of rotation of the projectile.
  • the displacement of the rotor from the first to the second position may be due to the action of centrifugal force on the rotor whose center of gravity is eccentric, even if its geometric shape is of revolution, or to the action of at least one spring, or else the combined action of centrifugal force and a spring.
  • the movable member is constituted by a slide whose sliding direction is perpendicular to the axis of rotation of the projectile.
  • the displacement of the slide between its two positions may be due to the centrifugal force alone, to at least one spring or to a combination of the two.
  • the movable member may include a central body on either side of which are provided covers which are integral with it and which, in the case of a rotor, each carry a pivot, for mounting the rotor in said recess of the projectile , the clock mechanism being housed at least partly in the central body.
  • the trigger lever comprises at one of its ends a hook cooperating with a first notch of the periphery of the recess of the housing of the movable member in the projectile, to maintain this member in the first position.
  • This trigger lever may further include a locking finger inhibited in the first position but capable of cooperating with a second notch on the periphery of the recess of said housing, to maintain the movable member in its second position.
  • This safety device can comprise an inertia lock and this can be provided either for blocking simultaneously, or for simultaneously unlocking the regulator of the clock mechanism and the release lever.
  • the moving part of the clockwork mechanism may include an eccentric mass; however, it can also be attached to a more eccentric arm.
  • the device according to the invention shown in FIGS. 1 to 4, consists of a rotor 1, provided with axial pivots of rotation 2 and 3 and comprising an intermediate cylindrical body 4, closed by two end covers 5 and 6, of which the pivots 2 and 3 are respectively attached.
  • the cover 5 is also cylindrical and covers the entire opposite face of the intermediate body 4.
  • the cover 6 has the shape of a disk sector and covers only part of the face opposite the intermediate body 4.
  • the latter comprises an eccentric primer housing 7, capable of being brought by rotation of the rotor 1, in the axis of rotation 13 of the projectile which happens to be the axis of the pyrotechnic chain, said eccentric primer housing 7 not being covered by the cover 6.
  • the rotor 1 is mounted in a cylindrical housing 8, provided in the rotating projectile 9 for which it is intended.
  • This cylindrical housing 8 comprises bearings (not shown) in which the pivots 2 and 3 are mounted and which define therewith an axis of rotation 14 for the rotor, the axes 13 and 14 being parallel.
  • the rotor is normally prevented from rotating relative to the projectile 9 by the hook 10 of a trigger lever 11, engaged in a peripheral notch 12 of the housing 8.
  • the housing 8 is eccentric relative to the axis of rotation 13 of the projectile, but said axis 13 is located inside said housing 8.
  • the center of gravity of the rotor 1 is eccentric relative to the axis 14 .
  • the pinion 16 acts as an escapement mobile for a clockwork mechanism further comprising a motor mobile 17, a first intermediate mobile 18 and a second intermediate mobile 19.
  • the axes of the various pinions 16 to 19 are parallel to the axis 13.
  • Figure 4 illustrates the kinematic chain formed by these pinions 16 to 19.
  • the movable motor 17 comprises an eccentric mass 20, on which a force of inertia F 1 is exerted, when the rotor 1 is driven in rotation about the axis 13, owing to the fact that it is linked in rotation by the hook 10 with the projectile 9.
  • the axis of the movable motor 17 passes through the intermediate body 4 and comprises, at its end directed towards the cover 6, a half-moon section 21, cooperating with the end 22 of the trigger lever 11, opposite the hook 10.
  • the trigger lever 11 is mounted between the intermediate body 4 and the cover 6, so as to be able to pivot around an axis 23, parallel to the axes 13 and 14.
  • the trigger lever 11 further comprises a locking finger 24, capable of cooperating with a locking notch 25, provided at the periphery of the housing 8, when the rotor 1 has been able to rotate relative to the projectile 9.
  • the position of the mobile motor 17 is adjusted so that, via the half-moon 21 and the end 22, the rotor 1 is locked in the housing 8 by the cooperation of the hook 10 and the notch 12 and so that the primer disposed in the housing 17 is outside the pyrotechnic chain.
  • the device according to the invention comprises an anchor lock 26 pressed by a spring 27 against the anchor 15, to prevent the latter from tilting about its axis.
  • the latch 26 moves outwards by unlocking the clock mechanism and the rotor.
  • the force F 1 exerted on the eccentric mass 20 of the movable motor 17 starts the clock mechanism.
  • the rotation of the mobile motor 17 rotates the half-moon 21 (arrow F 3 ) and the trigger lever 11 rotates around the axis 23, in the direction of the arrow F 4 under the action of the centrifugal force.
  • the hook 10 then leaves the notch 12, which unlocks the rotor 1 of the projectile 9.
  • the rotor 1 therefore rotates in its housing 8 around the axis 14 in the direction of the arrow F 5 .
  • the rotor 1 consists of a cylindrical intermediate body 4, closed at its two ends by covers 5 and 6 also cylindrical, carrying the pivots 2 and 3.
  • the housing d the primer 7 is located in the body 4 and opens into the cover 5.
  • the rotor 1 is rotatably mounted in the housing 8 provided in the rotating projectile 9 and is prevented from rotating by the hook 10 of the trigger lever 11, engaged in the peripheral notch 12.
  • an anchor 15 Between the intermediate cylindrical body 4 and the cover 6 are mounted, an anchor 15, a pinion 16, a motor mobile 17, a first intermediate mobile 18 and a second intermediate mobile 19.
  • the movable motor 17 is integral, by its half-moon end 21, with an eccentric arm 30 housed between the intermediate body 4 and the cover 5.
  • the trigger lever 11 pivotally mounted about its axis 23.
  • the device according to FIGS. 5 to 9 comprises a sliding inertia lock 32 passing through the central body 4 and capable of either blocking the trigger lever 11 and the anchor 15 simultaneously, or of simultaneously releasing the trigger lever 11 and anchor 15.
  • the clock mechanism and the rotor are unlocked.
  • the force F exerted on the eccentric arm 30 of the movable motor 17 starts the clock mechanism.
  • the rotation of the mobile motor 17 rotates the half-moon 21 and the trigger lever 11, after erasing the centrifugal spring 31, rotates around the axis 23, in the direction of arrow F 4 under the action of centrifugal force.
  • the hook 10 then leaves the notch 12 and the rotor 1 can rotate around the axis 14 until the locking finger 24 enters the notch 25.
  • the mobile motor 17 has been eliminated, and a lock has been provided anchor 26 resiliently pressed for a spring 27, and an inertia lock 32, blocking the trigger lever 11. Furthermore, a toothed wheel 33 integral with the rotor 1 and concentric with it is engaged with a pinion 34 integral in rotation of the intermediate mobile 18 and concentric with it.
  • the clock mechanism begins to count and the hook retracts under the action of the force F 4 .
  • the action of the centrifugal force turns the rotor 1, whose center of gravity is eccentric relative to the axis 14, the pinion 34 rolling without sliding on the fixed toothed wheel 33.
  • FIG. 11 is close to the device of FIG. 10. However, the lock 26 has been removed, but on the other hand, a spiral spring 35 is provided to promote or cause the rotation of the rotor 1, depending on whether the center of gravity of the rotor is offset or not by relative to the axis 14. In addition, a spring 36 is provided to assist in the tilting of the trigger lever 11.
  • FIGS. 12 to 15 illustrate embodiments of the device according to the invention, in which the movable member consists of a slide 40, housed in a radial recess 41 of the projectile 9.
  • the slide 40 carries a mechanism 15, 19, 21.30 to 32 similar to that of the device in FIGS. 5 to 9.
  • the hook 10 is engaged in a notch 12 provided in the wall of the recess 41 in the projectile 9.
  • the eccentric arm 30 has been omitted and replaced by a spiral spring 42, serving as a motor for the mobile 17.
  • a spring 43 is provided for exerting a force, in the direction of the force F 5 , on the slide 40.
  • a spring 44 is provided to assist in the tilting of the trigger lever 11.
  • the device of FIG. 14 does not include a mobile motor 17, a half-moon 21, nor a release lever 30.
  • the mobile 18 is engaged with a pinion 45, itself engaged with a rack 46 secured to the wall of the housing 41.
  • the slide 40 moves under the action of the force F 5 so that the pinion 45 rolls on the rack 46.
  • housings 7 were intended to contain a initiation of fire initiation, it goes without saying that these housings 7 could contain an intermediate charge between an initiation initiation and explosives placed outside the rotors or slides or else could be only a fire transmission channel between this primer and these explosives outside the moving member. In these cases, the movable member which would be interposed in the pyrotechnic chain instead of being the beginning, would act as a retractable screen.
