Definitions

  • the object of the present Patent application is a Mechano-Electronic Fuze for hand-grenade, which, in addition to the function for which it was designed, affords a number of advantages described hereinafter, and others that are inherent in its organisation and constitution.
  • the utility of this ammunition is dependent on the power of its explosive charge and on the characteristics of its fuze.
  • the fuze must be absolutely safe during storage, carriage and launching. It must also fire the explosive charge either after a delay once the grenade is launched, or upon the grenade striking a solid object.
  • the energy supply for this Mechano-Electronic Fuze for hand-grenade comprises a simple spring which, upon being released from any mechanical safety devices, actuates a minute electric generator whose power supplies an electronic safety and timer assembly and finally an electric detonator which, by either changing its position relative to a multiplier or removing a protective barrier, or otherwise howsoever, takes up a position to trigger a multiplier which shall in turn set off the main explosive charge.
  • the Mechano-Electronic Fuze for hand-grenade subject of the present Patent application provides improvements and original elements over fuzes conceived for a similar use because:
  • Figure 1 is an external side elevation view of an embodiment of a mechano-electronic fuze adapted to the body of a hand-grenade.
  • Figures 3, 4 and 5 illustrate the same number of internal views of an embodiment of a mechano-electronic fuze.
  • Figures 6 to 9 illustrate successive stages of the functioning of the mechano-electronic fuze.
  • Figure 10 is a diagram of the electronic module.
  • the Mechano-Electronic Fuze proposed in the present Patent application has been devised to be used in hand-grenades, albeit without limitation. Its external shape is therefore adapted to be fitted in hand-grenades most widely used nowadays, although it may be adapted to any other shape with only slight alterations.
  • the Container (100) in turn includes:
  • the Lever Safety Device (200) may, as aforesaid, have any conventional design. A possible embodiment thereof is described as an example, which would include:
  • the Slide (400) includes:
  • the Electronic Module (500) includes:
  • the Electronic Module (500) is thereby simplified, and the functioning of the Detonator (601) is not dependent upon mechanical movements. Furthermore, when inoperative, the Detonator (601) remains in closed circuit which, albeit not a short-circuit, is over-safe.
  • the Mechano-Electronic Fuze subject of the present Patent application guarantees a safety time after launching during which no power is available to set off the detonation, and a very reliable functioning after a delay, adjustable by design, and precisely controlled.
  • the Mechano-Electronic Fuze subject of the present Patent application ensures that, if the Detonator (601) is detonated and given that the latter must have been kept aligned with the Multiplier (602), the detonation shall pass to the Multiplier (602) and thereafter to the explosive charge in the hand-grenade.
  • the fuze would be ready to function by impact against the ground or against any obstacle, and in the event of the impact not taking place or not being sufficient to trigger the impact detector, the explosion would take place after the pre-set delay.
