Definitions

  • the present invention relates to a launching device or launcher, standardized and modular, specifically designed for the purpose of obtaining a distant and controlled launch of hand grenades (hereinafter identified with the abbreviation HG), but which can also be used for the remote launch of part of HGs, e.g., only the body of the HG (without fuse), in practice a hollow body filled with explosive material, activated by an electronic multimodal/multifunction detonator or only the fuse, pyric or electronic, of the hand grenade/HG, separated from its explosive body, and also non-lethal HG (smoke/tear/stunning flash-bang, etc., or for recreational use, e.g., Soft-Air Gaming), or also only hollow shafts/handles containing detonating material, e.g., the same supports for the hand grenades described below, in this case actuated by an additional multimodal detonator, indispensable for the detonation to occur which can be activated with different modes
  • Hand grenades of ancient memory and of very low cost but of high tactical effectiveness, usually have a metallic or plastic or other type of synthetic resin casing (the most modern), which can have various geometric shapes, for example: jar / ball / pineapple / vase, etc., containing explosive material therein, e.g., TNT, Compound A, Compound B, etc., to which is associated a detonator, also called a pyric fuse or, those of the last generation which are much more reliable, piezoelectric/electronic fuses, operable by the user by means of a lever, generally called “hand lever” and safety lever, secured in a rest/locking and safety position by a pull ring or similar means, called “safety pin with pull ring" before the launch, which is followed by the explosion after a predetermined time when, the safety pin having been removed, the HG is thrown by hand, thus being able to open the hand lever, pushed by an elastic element, generally a spring of various configuration, which activates the fuse,
  • the launch can occur by directly gripping the HG with one hand, in which case relatively modest distances are reached, around 10-15 metres, and even up to 20-25 metres and beyond but only in the best throwing conditions, but very rarely obtainable on the field or in battle due to difficulties of a correct launch positioning to avoid exposing oneself to the offensive attacks of enemies.
  • hand grenades were proposed with a support shaft, generally a wooden handle, housing the detonator actuating means, generally with a pull ring, in practice obtaining the leverage effect for an even more distant launch. In this case distances of around 25-35 metres and more are reached in the best conditions, which is not said, however, to be the safest for the operator on the ground.
  • One such example is the well-known German HG "stick hand grenade" of the First and Second World War, Mod. StHG 24 (Model 24) and StHG 39, where the explosive charge, in the form of a jar with a charge of about 160 gr. and up to 200 gr.
  • Italian patent application no. 10201800000012 and PCT/IB2019/050021 Italian patent applications no. 102018000003123 ; 102018000003125 proposed a launching means, in various variations, basically comprising a hollow shaft or hollow handle in generally synthetic material (but which could be in metallic material, wood, various pressed recovered material etc.), also this time hollow but without internal HG activation means (as in the case of the StHG 24 and the like) therefore optionally fillable with an additional explosive charge, to which a gripping hand or cage is attached for the retention of the HG, whatever the type and geometric shape.
  • the explosive charge possibly present in the handle is added to the explosive charge of the HG, greatly increasing the explosive power, in practice adding to the aforementioned "leverage effect" of the handle which allows a greater range, also a greater explosive charge, therefore a better tactical result.
  • WO 2016/188869 A1 and WO 2017/009197 A1 disclose hand grenade launchers which use pneumatic systems to cause the hand grenade inserted into the launcher to launch.
  • the object of the invention is to overcome the drawbacks and limitations of the known launching technique, providing a launcher of grenades or hand grenades or exploding media of various types, but not limited only to these, which is hardly bulky, of low weight and therefore easily transportable, of simple and intuitive use and with parabolic ranges covering much greater distances than the common hand launch, therefore from 65-70 metres and up to over 100-120 metres, depending on the weight of the object to be launched: in practice a small portable, robust, 5bar watertight, silent mortar, therefore difficult to identify upon launching.
  • Another object of the invention is to provide a grenade launching device which is hermetically sealed and therefore usable also in underwater incursions, with tactical exit of invaders from submarines or from SDVs (Swimming Delivery Vehicles) which are hidden and operating under the sea surface.
  • Another object of the invention is to provide such an HG launcher which is silent and which upon launching does not leave light or smoke trails, thus favouring operators on the ground who become very difficult to trace, and which is adapted to launch any type of HG or explosive media.
  • Another object of the invention is to provide such a launcher which is able to launch even only the fuses of the HGs placed on suitable launching means, for example the same launching means as the HGs (hollow shafts/handles with retaining members), with the explosive material of any kind or type therein, thus being able to obtain a different type of grenade with explosive material content, the quantity of which depends on the length of the launching means (hollow shaft/handle) and, therefore, the filling capacity.
  • a further object of the invention is to provide such a launcher which is able to launch even only the fuses of the HGs placed on suitable launching means, for example the same launching means as the HGs (hollow handles with retaining members adapted to the need), with the explosive material therein, thereby being able to obtain another type of small, inexpensive but very effective "improvised” grenade or even a small but very effective depth charge, therefore with an excellent cost/benefit ratio.
  • Another object of the invention is to provide such a launcher which is able to launch even only the fuses of the HGs placed on suitable launching means, for example the same launching means as the HGs (hollow shafts/handles with retaining members), but without any explosive charge added, for the sole purpose of acting as an "Immersed Divers Call”: although a small detonation, it is in fact amplified by the water and serves to call divers to the surface within a radius of hundreds of metres.
  • Another object of the invention is to provide such a launcher which is able to launch even standardized hollow modular cylindrical elements, containing different explosive charges used as an alternative to HGs or fuses in land or sea operations, such as small depth charges for the prohibition of hostile divers to ports/arsenals, activated by a specific independent and calibratable electronic multimodal detonator, in the time and/or in the activation depth depending on the need.
  • Another object of the invention is to provide such a launcher of various types of grenades which is light, small, robust, reliable and mass-produced at low cost and, if necessary, therefore disposable.
  • a launching device for hand grenades can only be used essentially in a purely military field, and/or generally in the field of armed forces and police and, with some other measures, also in a recreational field, using for example, but not limited to, a special shaft or support adapted to launch recreational HGs, absolutely inert and harmless, for example in the field of Soft-Air Gaming, where HGs are used which are aesthetically completely similar to those for military use but completely inert and harmless, or with very weak explosive charge, but such as to spray a cloud of talc or to expel at large ranges a multitude of very light plastic balls of different colours also immersed in a completely harmless dye or, finally, activate a strong acoustic warning (e.g.: a siren etc.).
  • a strong acoustic warning e.g.: a siren etc.
  • a peculiar feature of this launcher device is that it can launch, silently, therefore with the additional advantage of the difficult localization of the launch point, any explosive and non-explosive object, for example: lethal and non-lethal HGs, or other similar devices, lethal or non-lethal, at a distance much greater than that which can be obtained with a manual launch, with a parabolic trajectory, typical of a mortar, in practice this launcher device, also for its lightness and portability, can be defined as an individual portable mortar, in fact solving a tactical problem without exposing the operator in the field who can perform distant launches even of approximately 50-70 m and up to over 120 m, depending on the weight of the object, to be launched safely and without exposing himself to the offensive attacks of enemies, therefore well beyond the distances obtainable with the hand launch alone.
  • the invention has basically three variants produced with standardized and interchangeable parts for an easier and less expensive industrial reproducibility, the first of these with a sub-variant which affects only one component: the high pressure HP air tank.
  • Variant no. 1 with single barrel Launcher with only pneumatic drive by virtue of a tank containing high pressure air which can be recharged, when necessary, by means of a valve on the bottom.
  • Sub-variant of the single-barrel launcher 1 launcher mentioned above but, instead of the standard high pressure tank, it has a container which will accommodate multiple high-pressure compressed gas cartridges/cylinders, in the case in question, present in the number of 4, so as to have a quick recharge, simply replacing, even in the field, the HP cartridges very rapidly
  • variants with 1 and 3 (or more) barrels also have the possibility of being supplied by an external and independent compressed air source, such as a compressor for compressed air, or large high-pressure cylinders which can be found on fixed land stations, or on mobile road or naval vehicles, etc.
  • an external and independent compressed air source such as a compressor for compressed air, or large high-pressure cylinders which can be found on fixed land stations, or on mobile road or naval vehicles, etc.
  • Variant no. 3 with single barrel with "hybrid"-type drive, pneumatic + mechanical, with elastic pushing elements tensioned by a high torque electric motor powered by rechargeable batteries, suitably geared down and with high pressure cylinder cartridge, in combination, to increase the launch power.
  • the greater launch distance will be obtained, of course, with the selected combination - optionally - of pushing of mechanical + pneumatic origin through a rapidly interchangeable HP cartridge/cylinder, inserted in the handle/grip provided with a trigger.
  • High-pressure (HP) air is intended as compressed gas at very high pressures, and not limited to these gases, e.g.: CO 2 or nitrogen (N) etc. and, sub-variant launcher device 1 is intended as the launcher 1 having, in place of the standard or special tail HP tank made of aluminium or "blown" technopolymer with very high resilience, a tail container with, indicatively but not limited to, 4 or more commercial or specially made HP cartridges/cylinders; the version 3 launcher device is intended as a launcher body with inserts, one or more elastic pushing elements, e.g.: rubber elastic bands or a coil spring built for this specific purpose, or two coil springs arranged coaxially or even a volute spring which, once freely compressed, when released, instantly issues a large amount of pushing energy necessary to launch an assembly composed of a hollow shaft/handle plus any explosive optionally inserted therein, an HG (lethal or non-lethal, therefore without additional explosive added in the handle), i.e., a plurality of HGs or
  • the invention relates to a portable launching device of hand grenades (10), but not only those, as described above, carried by a gripping and retaining member (11) mounted on a substantially cylindrical and hollow shaft/handle (20), comprising a tubular body (30) bearing at one end an enlarged head (34), adapted to house, respectively, said cylindrical shaft (20) and said gripping member (11) with the HG (10), or other as mentioned above, and a threaded cover (35) adapted to seal said enlarged head (34) in a watertight manner; at the other end of said tubular body (30) being fixed a compressed air tank (36) - Variant 1-, the discharge of which is controllable by means of a grip (41) with an HP cylinder inserted which is completely similar to Seltz cylinders for the operation of the rapid HP air discharge valve, positioned between the tank and the launcher body, by means of a trigger (45) mounted on the grip itself and made integral with said tubular body (30), also including a qualifying accessory and indispensable
  • the launching device for hand grenades and/or fuses according to the invention has been indicated as a whole with the reference number 1, and will be described in its component parts with particular reference to the exploded view of figure 4 and the various sections;
  • the figures depict an HG 10 of substantially spherical shape, as many HGs in use, housed in a gripping member 11 comprising a plurality of elastic appendages 12 determining an inner cradle of a shape corresponding to that of the HG 10.
  • the ends of the elastic appendages 12 face outwards to accommodate a strap, such as in nylon 13, adapted to retain the HG 10 in place and in absolute safety.
  • the HG 10 can be of other shapes as present in the various deposits/arsenals, for example: more elongated, ogival or similar, jar-shaped, cylindrical, vase-shaped, etc., in which case the elastic appendages 12 of the gripping member 11 will be correspondingly shaped to adapt to the shape of the HG.
  • the gripping member 11 On the opposite side to the appendages 12, the gripping member 11 has a threaded shank 16, which screws inside an open end of a hollow shaft 20, the other end of which is closed, by means of a dividing wall 21 but also with a threaded plug 19.
  • the shaft 20, which can also obviously serve for a manual launch of the HG 10 can optionally be filled with explosive charges 22 adapted to increase the offensive power of the HG.
  • the figures also show a hand lever 14 for operating the HG, blocked by a safety ring 15.
  • the actual launching device comprises a tubular or barrel body 30, obtained by extrusion of plastic material, or made by injection moulding plastic materials, so that longitudinal grooves are formed on its side surface in the undercut 31, Fig. 8 , serving the purposes described below.
  • the tubular body 30 has two externally threaded end shanks 32 and 33.
  • An enlarged head 34 is screwed onto the shank 32, of such size as to house the gripping member 11 carrying the HG 10 which may also have different diameters depending on the size of the HG or the body to be launched.
  • the head 34 is closed at the front by a screw cover 35 adapted to keep the device and its contents safe and water, dust and mud-tight before launching.
  • a compressed air tank 36 is instead screwed to the other threaded shank 33 which can be made of aluminium or a Technopolymer obtained by blowing.
  • the device also comprises two gripping handles or grips 40 and 41 mountable in an adjustable position along the tubular body 30.
  • the handles/grips 40, 41 have a series of teeth 42 above of complementary shape to the grooves 31 provided on the tubular body 30, so that they can be inserted from one end of the body 30, for example before the assembly of the enlarged head 34, and slid therealong to the desired position, where they remain blocked by simple interference or, possibly, with the aid of additional fixing means in place, such as a locking screw or gluing.
  • the front handle/grip 40 i.e., that closest to the enlarged head 34 is made of solid material, but may be hollow both to lighten it and for a different/complementary future use, in this case serving only as a handle, while the other handle/grip 41, on the compressed air tank 36 side, is internally hollow and is connected to the compressed air tank 36 by means of a connection conduit that can also be of the flexible type 43.
  • a cartridge of gas such as of the Seltz type
  • gas such as carbon dioxide or nitrogen or other gases
  • the opening of the gas cartridge being controllable by a trigger 45 of the handle 41 to release the gas contained therein which, through the conduit 43, controls a pneumatic valve with rapid discharge of the compressed air contained in the tank 36 for the launch of the HG 10, with relative gripping member 11 and hollow shaft 20.
  • a battery pack can be connected by means of an electrical conductor through the conduit 43, to connect to a rapid discharge solenoid valve, always arranged between the compressed air tank 36 or the container for the cartridges/cylinders 37 and the launcher body.
  • the trigger 45 acts on an ON-OFF switch, normally open, closing the circuit with the solenoid valve with the pressure on the trigger, the activation of which causes the rapid discharge of the compressed gas and the exit of the hollow shaft + HG assembly.
  • a trigger lock safety is provided, and the cover can have a red ribbon indicating the closed lock and the same cover tightened closed, thus to be removed at the moment of launching.
  • the ring 15 is shown, which safely holds the hand lever 14 of the HG actuation.
  • Such a ring is normally removed during the arming step, since the hand lever 14 is compulsorily held in a lowered and safety position by the inner wall of the enlarged head 34, as shown in figures 2 and 5 , and is released only after the launch, as an exit from the enlarged head similar to a hopper, as shown in figure 6 .
  • O-rings 25 are arranged around the hollow shaft 20 adapted to seal against the inner wall of the tubular body 30.
  • the launching device according to the invention can be easily gripped by the user with the two handles/grips and oriented with the desired angle with respect to the horizontal line according to the parabola and/or the range to be obtained.
  • Tests carried out have shown that distances greater than 100 metres can be reached, and also around 120 metres depending on the weight of the HG + hollow shaft/handle with explosive added: in a test carried out with a total launched weight of about 650 grams there was a maximum range of 122 metres with impact detonation (launcher variant 1).
  • the overall length of the launching device variant 1 and sub-variant 1, according to the invention does not normally exceed about 550 mm and the weight, including the HG with hollow shaft and auxiliary charge, is around 5.5-5.9 kilograms, thus being extremely manoeuvrable and easily transportable, in maximum safety, even in restricted environments, such as armoured, aerial and/or naval vehicles, especially small assault and submersible units, even submerged, with hostile divers exiting from the notoriously very narrow floodable diver escape/entry sentry box.
  • the launching device according to the invention is 5bar watertight and can therefore be used in any marine environment for diving as well as terrestrial, sandy or rocky environments, even with extreme operating climates, from -30° to +55°C, and shockproof because it is made of a technopolymer which is extremely resistant to impacts and thermal shocks.
  • the launching device according to the invention is used in attack actions with curved shot even on embankments/buildings up to 10-15 metres high; in territory control or raking actions; in building reclamation actions, etc.
  • All the components of the device are made of high resilience technical plastic material (technopolymers) in particular, e.g.: PC, or ABS+PC, with the exception of the compressed air tank 36 which is normally in aluminium even if a tank in a technopolymer produced with the technology of blowing highly resistant plastics is envisaged in the future.
  • the tubular body 30 is preferably obtained by drawing but could also be produced by injection moulding with very particular moulds with very high technology, while the enlarged head 34, the threaded cover 35 and the handles 40 and 41, by injection moulding.
  • figure 9 always depicts the single-barrel launcher but in sub-variant 1 which differs only for the rear part and, in particular, the one which replaces the tank 36 with the container 37 which houses 4, but not limited only to 4, High Pressure Cartridges/Cylinders inserted in a removable plate with protrusions/appendages or retaining fingers, to facilitate the retention and rapid exchange of the Cylinders when discharged.
  • Figures 9 and 10 also show, as a demonstration of the absolute possibility of the use of any and all HG present today in the various World Arsenals, an HG other than the spherical one previously described in Fig. 4 inside the launcher, which has a "bottle" shape and with a piezoelectric fuse typical of a Spanish manufacturer.
  • Figures 11 and 12 illustrate a multiple launcher with 3 barrels, indicated with the reference number 100, in which several launching devices 1 (in the example shown in the number three) substantially identical to that shown in the previous figures, are carried by the same pair of handles/grips 40 and 41.
  • an aluminium cylinder for HP compressed air calibrated up to over 200bar 101 is arranged, with a reducer/pressure regulator (not shown) for multiple launches, single or multiple salvo which, through connections 102 goes to feed the storage tanks 36 in this case, however, smaller than Version 1, of the various launch barrels 30.
  • a selector (not shown) is provided to selectively trigger the various devices by actuating the trigger 45 (single shot), or actuating the selector can cause the simultaneous launch of all devices/barrels with a salvo of all 3 hollow shaft/handle assemblies (+ any additional explosive inside) plus HG or other.
  • a modular and interchangeable integrated tank 36 is used, fixed on a barrel 30, to launch, by way of example, an assembly composed of a hollow shaft/handle 20 with, optionally, additional explosive cartridges 22 inside and, retained by special retaining members 11-12, any HG, here a spheroidal type HG 10 depicted: by pressing the trigger 45, after removal of the threaded and watertight cover 35, from the enlarged head 34, a rapid discharge valve is activated, driven by a commercial cartridge/cylinder (such as those of Seltz type) inserted inside the handle/grip 41 or, alternatively - not shown - by a solenoid valve powered by batteries, possibly inserted in the handle 40 which, opening, launches a powerful jet of high-pressure compressed air which expels the hollow shaft/handle plus HG assembly at a remarkable distance with a curved/parabolic mortar-type launch depending on the launch angle, in this case very light,
  • a commercial cartridge/cylinder such as those of Seltz type
  • the sub-variant 1 operates and behaves in exactly the same manner as the variant 1, since the only difference is given by a different type of tank 37, better identifiable as a container illustrated in Figures 9-10 of the same shape as the tank 36, but with 4 or more high pressure cartridges/cylinders inserted, for faster recharging, with the simple replacement of the cylinders themselves which can be carried out very quickly and safely also in the field.
  • Variant 2 is fundamentally similar to variant 1 and sub-variant 1 in that the principle of exploitation of high pressure compressed air is always in operation for the more distant launch of a lethal/explosive object as described above and/or different assemblies described below, or even non-lethal (tear gas/stunning HG, etc.) but, in this specific case, there is the advantage of having more barrels, compared to the single barrel 30 of variants 1 and sub-variant 1, allowing a plurality of salvos for a better area saturation where necessary.
  • a THREE-barrel launcher 30 (but it could be 2-3-4 or more barrels) is depicted arranged, seen in a master cross-section, in a triangle for better portability even in the narrowest spaces of assault vehicles with, positioned therein, a High Pressure compressed air/Compressed gas tank in Aluminium 101 which, through the conduits 102, carries the compressed air in the smaller storage tanks 36 placed at the opposite end of the enlarged head 34 and threaded cover 35.
  • the quick discharge valves of the various barrels 30 can be activated, exactly as in variant 1 and sub-variant 1, selectively or simultaneously for the launch of one or more assemblies composed, for example, of a hollow shaft/handle 20 (with/without additional explosive 22) retaining members 11 and 12 and spherical HG 10 as depicted in the axonometric view in longitudinal median section 12.
  • the multi-barrel variant 2 finds valid use on light armoured vehicles or light naval vehicles which can embark even larger compressed air/gas cylinders calibrated even above 200 bar, for a continuous recharging of the central cylinder of variant 2 always through a pressure reducer to be placed in line.
  • the hybrid variant 3 uses a good part of the standardized components of the variant 1, sub-variant 1 and variant 2 but, unlike these has, in addition to a pneumatic component (given by an HP air cartridge/cylinder inserted in the handle/grip 41 which is easily replaceable, when discharged, with a new full one), also a mechanical pushing component provided by elastic elements, for example elastic bands, single or double coaxial coil or volute springs, with space saving, which have the purpose of pushing that which is inserted in the barrel 30 outwards with the maximum pushing energy, sufficient for an incomparably more distant launch than the traditional launch by hand.

  • the trigger 45 In the hollow handle/grip 41 where the trigger 45 is also placed, there is a cartridge/cylinder at high commercial pressure which, in this specific case, if activated by a two-position selector (not shown) and by the trigger 45 can operate as a rapid discharge of high pressure air for the launch of that which is inserted in the barrel 30, in the configuration shown an assembly composed of a hollow shaft/handle with integrated retaining members and integral parts in the same which retain a fuse for HG in place.
  • the model of the fuse 17 depicted with the two spacers 12 and 13 on the hand lever 14, inserted by restraint one into the other, is that produced by a well-known North-European multinational.
  • this assembly - hollow shaft/handle + fuse - under examination is very light (about less than half of a hollow shaft/handle assembly with or without explosive material inside with an HG regardless of the model, and with an average variable weight of only the HG of 350 -:->500gr.), the discharge of high pressure air from the HP cartridge/cylinder is sufficient for a very distant launch of this assembly, approximately 45-55 m; if the elastic element (in this illustration the spring 47) is also to intervene in the launch, the pushing generated by the coil spring 47 added to that released by the cartridge/cylinder inserted in the hollow shaft/handle 41, as a "booster", allows launches well above 100 m depending on the total weight of the object launched.
  • hybrid launcher in addition to being lighter and more compact than variants 1, sub-variant 1 and variant 2, is that it has a considerable pushing which could further increase with the use, as an alternative to the single coil spring, of a pair of coaxial springs and that of allowing repetitive launches, theoretically more than 6-8 launches per min (just enough time to bring the spring back into compression after a launch), also at a great distance with the help of HP cartridges/cylinders as boosters, easily and quickly interchangeable when needed, for an increased pushing and always with a high degree of silence, a fundamental requirement for the safety of operators in the field.
  • the two bronze compression bars 931 are opened by divergence, which compress, when tightened, the two faces 932 of the carriage 93, where a portion of the female thread which interfaces with the male thread of the worm screw 94 is obtained, indicated in figures 21 and 22 , dragging the carriage 93 which can slide very quickly, towed by the spring 47 which extends, pushing violently out through the four-lobed plate 46 with a spike, the hollow shaft/handle assembly with a fuse contained in the barrel 30.
  • the carriage 93 then stops on the stop block located inside the "nacelle" 38, also acting simultaneously on the microswitch/limit switch -IN2- which, remaining closed on the pressure of the carriage at stroke end, allows the restart of the electric motor 91, if the normally open button P is pressed, which closes an activation circuit and, at the same time, the two bronze compression bars 931 automatically return to close, tightening the carriage 93 again acting on the two faces 932 on the worm screw 94, so as to be able to drag the carriage 93 again - so as to tension the cable 49 - which compresses the spring 47 again, until touching the microswitch/limit switch IN1 which stops the motor with the spring tensioned and ready for a new launch.
  • the carriage 93 is in any case guided by the fins 933 placed on both sides of the carriage itself, which are inserted into the guides in PFA/Teflon 934 (to facilitate their sliding), so as to always remain centred on the worm screw 94, despite the violent forwards movement when freed from the worm screw 94 itself.
  • the carriage 93 is composed of two steel plates 930 with a convex shape 932 at the bottom which carries therein a female thread which matches the male thread of the worm screw 94 held together, but normally separated, by some pins with antagonistic springs 935 therein which always keep the two faces of the plates pushed outwards so that, only when the bronze pushing/block bars 931 are pressed on the external faces of the convex shapes 932, the worm screw 94 can engage and act in rotation, dragging the carriage 93 at stroke end.
  • a pulley 193 is fixed to the top of the carriage 93, in whose throat the cable 49 for tensioning the spring 47 slides as shown in figures 21 and 22 .
  • all HGs When launched, all HGs generally have a prefixed triggering time which ranges from 3.5 to 4.5 seconds, therefore completely insufficient time because, when launched, the HG travels in flight, if a distant shot is desired, a distance greater than that obtainable with the traditional launch by hand, as is known.
  • Figure 23 is a median sectional view of a launching device of hand grenades according to the invention, complete with an additional multimodal/multifunction detonation module or unit 50, fixed to the hollow shaft or handle 20 supporting the HG 10;
  • figure 24 is a schematic view of a transmitting unit 500, for non-limiting example, of home automation derivation usable with the multimodal launching device according to the invention;
  • figure 25 is a sectional view of only the additional multimodal/multifunction detonation module 50;
  • figure 26 shows in a box, respectively, a side view -A- and a longitudinal section view -B- of an HG 10 with its supporting hollow shaft 20 and additional multimodal/multifunction detonation module 50;
  • the HG launching device has been indicated as a whole with the reference number 1 and comprises a tubular body or barrel 30, having two externally threaded end shanks 32 and 33, on which an enlarged head 34 closed at the front by a screw cover 35, and a tank of compressed air/compressed gases (e.g. CO 2 or Nitrogen, etc.) 36 are respectively screwed.
  • compressed air/compressed gases e.g. CO 2 or Nitrogen, etc.
  • the tubular body 30 bears a pair of handles 40 and 41, of which the front one 40 closest to the enlarged head 34 serves only as a grip; the other handle 41, on the side of the compressed air tank 36 bears a trigger 45, which controls the discharge of the compressed gas into the tank 36.
  • a hand grenade 10 which merely by way of example in the accompanying figures is shown as a spherical shape, is carried by a gripping and retaining member 11 provided with a threaded shank 16 (see in particular figure 5 ) which screws inside the open end of a hollow shaft 20, the other end 21 of which is closed.
  • the hollow shaft/handle 20 can also serve, of course, for a manual launch of the HG 10, and is additionally filled with explosive charges 22 (explosive compounds of various kinds and types) adapted to increase the offensive power of the HG, regardless of the type or model.
  • an additional multimodal/multifunctional detonation unit or module 50 is mounted on the part of the closed end 21 of the hollow shaft 20, which will be better described below, having an externally threaded shank 51, adapted to screw inside an extension of the hollow shaft/handle 20 beyond said end and closed by the wall 21 to avoid damaging the possible explosive 22 present inside which, recommended for obvious safety measures, will be presented in the form of prepackaged cartridges.
  • the assembly shown in figures 23 and 26 consisting of the HG 10, the hollow shaft 20 and the additional multimodal/multifunction detonation module 50, is housed in the launching device (here shown in variant 1) as shown in figure 23 ; in particular the hollow shaft 20 and the additional multimodal/multifunction detonation module 50 are housed in the tubular body 30, with the multimodal/multifunction detonation module 50 itself arranged near the compressed air tank 36, while the HG 10 is housed in the enlarged head 34.
  • the hollow shaft/handle 20 can have different sizes (lengths).
  • the length of the prototypes made is 254mm/10" for a standard diameter of 33 mm.
  • Other prototypes, which are modular/standardized and integrable with each other, have been made for exactly half the length of the hollow shaft/handle 20, i.e., 127mm/5", with only one of the explosive charges 22 shown in the figure, and also in the 190.5mm/7.5" version, the explosive charges are recommended, as already mentioned, to be in the pre-packaged cartridge type also for safety and ease of handling.
  • the tubular body/barrel 30 of the launching device can be adapted correspondingly to the length of the hollow shaft 20 of 254mm/10" complete with an additional multimodal/multifunctional detonation module 50, or can be maintained in the standard length by appropriately filling, with adapter shafts of length as described above, the inner empty space of the tubular body 30, in the case of use of hollow shafts of lesser or different length.
  • the additional modular/multifunction detonation module 50 comprises a cylindrically shaped high-resistance technopolymer plastic body with knurled outer surface for better grip.
  • an explosive charge 60 is contained for the detonation of the compounds 22 contained in the hollow shaft 20 and the HG 10.
  • Any empty space between the explosive charge 60 and the closed end part 52 at the shank 51 is filled with a polyurethane spacer 53, or alternatively also with steel micro-spheres to increase and ensure the chain detonating effect.
  • the hollow explosive charge 60 internally incorporates a micro-resistance 61 which bends when crossed by current, triggering a micro-detonator 62, e.g., in mercury fulminate or other primer, which in turn detonates the hollow charge 60 and, thereafter, triggering the chain detonation of the explosive charges 22 and HG 10, greatly improving the tactical effect.
  • a micro-resistance 61 which bends when crossed by current, triggering a micro-detonator 62, e.g., in mercury fulminate or other primer, which in turn detonates the hollow charge 60 and, thereafter, triggering the chain detonation of the explosive charges 22 and HG 10, greatly improving the tactical effect.
  • a trivalent or trimodal electronic circuit 70 is arranged for the activation of the micro-detonator 62, connected with electrical conductors 71 to the micro-resistor 61 which, upon command, becomes incandescent by triggering the micro-detonator 62 and the hollow charge 60.
  • the trimodal electronic circuit 70 which serves as an independent detonator/trigger of the HG 10, is designed to operate in different modes:
  • a battery pack 80 Upstream of the electronic circuit 70 there is a battery pack 80 adapted to supply the aforementioned electronic circuit 70 through conductors 81 and to trigger the detonation.
  • the module is completed by a safety pressure switch 90 which activates the electronic circuit 70, changing state only after the jet of compressed air coming from the tank 36, or by simple pressure of the spike placed centrally on the four-lobed plate, has ejected the HG 10 - hollow shaft 20 - module 50 assembly, with a programmable safety delay of about 3"-5" or as requested when ordering the multimodal/multifunction detonator.
  • the additional multimodal/multifunctional detonation module 50 thus substantially comprises three well identified and distinct blocks (explosive/control/power) interconnected to each other with a multimodal and multifunctional capability, adapting to different situations and operational needs on land and at sea:
  • the non-limiting dimensions of the multimodal/multifunction module 50 are: length 75 mm, diameter 33 mm, corresponding to the diameter of the hollow shaft/handle 20.
  • the body of said module 50 is made of high-strength, knurled plastic material for easier grip.
  • the module 50 on the side opposite the shank 51, is closed by a screw plug 54 with a central hole 55 on a 6 mm recessed hexagonal key, for the passage of HP compressed air/gases so as to be able to activate the pressure switch 90 placed inside in a front position with respect to the hole.
  • the radio pulse activation occurs by means of a transmitting unit which can be a common remote control for home automation and also a cellular terminal operating on prefixed frequencies and on the frequency of the cellular terminals currently on the market, 900, 1800, 1900, 2100 MHz. It can also be programmed with NTF technology or other possible future technologies.
  • a transmitting unit which can be a common remote control for home automation and also a cellular terminal operating on prefixed frequencies and on the frequency of the cellular terminals currently on the market, 900, 1800, 1900, 2100 MHz. It can also be programmed with NTF technology or other possible future technologies.
  • Such a transmitting unit has been depicted at an extremely schematic indicative level in figure 24 and is indicated with the reference number 500.
  • It comprises an on-off microswitch slide 501, slightly recessed in the casing wall so that it can only be operated intentionally, by means of a pointed object. This is done for obvious safety reasons, to avoid unintentional operation of the remote control especially when the operator is in the field.
  • a standby button switch 502 is also provided, which can only be activated when the main switch 501 is in the ON state, which serves to activate the transmitter 500; a condition which can be indicated, for example, by the switching on of a red micro-LED 503.
  • a further button 504 allows to select the radio-pulse function or the timer function, signalled by further green 505 and yellow 506 micro-LEDs .
  • the dual functionality is operated by a selector microswitch slide 507.
  • transmitter unit 500 is purely exemplary, since it may have other functions depending on the operating needs on the ground or at sea because the additional multifunction multimodal detonation module has been designed for dual use on land/sea, recalling that a common properly programmed cellular terminal can also be used for the activation of the different functions.
  • the operation of the launching device whatever the variant, improved according to the invention, occurs indicatively but not limitedly as follows in the launching devices of variant 1, sub-variant 1 and variant 2: by operating the trigger 45, after having previously removed the front cover 35, the discharge of the compressed air contained in the tank 36 is caused, which expels the assembly consisting of the HG 10, the hollow shaft/handle 20 and the additional multimodal/multifunction detonation module 50. With a delay of 3" or 5", the pressure switch 90 changes state and activates the electronic circuit 70, which, depending on the mode in which it was set, i.e., for example by receiving a radio pulse from the transmitting unit in Fig.
  • the pushing plate 46 see figures 18, 19 and 20 , is provided with a steel "spike" which penetrates the threaded plug 54 to compress the pressure switch, closing a circuit and activating, in the chosen mode, the multimodal/multifunction detonator 50 screwed in the tail position of each type of hollow shaft/handle 20 and/or together with the additional explosive 22 with or without HG.
  • All the launcher devices mentioned here are able to launch at a considerable distance, on average double or triple and above of the traditional manual launch, any type and model of HG or fuses currently in use in the world FFAA, placed on the hollow shaft/handle 20 through customized and standardized retaining elements, but also standardized elements of different length and containment capacity of explosive material, e.g.,: hollow shafts/handles 254mm/10", 190.5mm/7 .5" and 127mm/5" but not limited to these standardized measures, which can be modulated in a stable and rational manner through joints and/or other standardized joint elements, as illustrated in figures 27, 28 , 29 and 30 where the accompanying figures clearly highlight the launch possibilities also, as a valid alternative to other explosive elements of low cost and high safety and efficiency, in addition to the traditional HG or Fuses currently in use and in particular:

  • the Bomb launchers with a pyric charge and explosive at the time of launch which inevitably reveals the launch area, putting the operators at risk of detection.
  • the range of the launching devices and its specific but not limiting ammunition presents great operational flexibility, as it is adapted to launch indifferently and without any external/physical alteration of any type of HG worldwide, and of any explosive object, also modular, since the barrel 30 can - optionally - also be elongated with additional modular units, for example of greater and/or shorter length, with female thread on the male thread side 32 and male thread on the enlarged head 34 to which it connects by screwing, as shown below: HG of every type and geometric shape, fuses of every model and type, pyric and electronic/piezoelectric, single hollow shafts/handles of every length - as previously specified - also in combination with each other in the various lengths with, inside an explosive charge of various nature, and activated by "natural" opening of the hand lever of the HG placed on top of said hollow shaft/handle, held by a special retaining cage, as shown in figure 4 and exiting from the enlarged head 34.
