In most preferred embodiment, projectile can be contained in the cartridge clip of type described in International Patent Application PCT/AU94/00124 and the PCT/AU96/00459.Such cartridge clip comprises a housing; A plurality of projectiles that are disposed axially in the housing are used for correspondingly the endoporus sealed engagement with tubular shell, and the discontinuous propellant charge that is used to advance corresponding projectile.

Projectile can be circular, general shape or boomerang shape, and the projectile tail of projectile can be uninfluenced, when boomerang advances in gun barrel, produces stable rotation, and this gun barrel can be the gun barrel of smooth inner bore.

Projectile charge can be to handle the solid block of the mode at the interval of projectile in gun barrel, perhaps propellant charge can be to be packaged in metal or other stiff case, this housing can comprise that is preset a trigger, and this trigger has and is suitable for the external contact device that contacts with electronic contact corresponding to the pre-determined bit of housing.For example, this trigger can provide a resilient contact, and this resilient contact can be withdrawn and be made the powder charge of packing to insert, and when with aperture timing being ejected to aperture, is used to handle the contact of meshing with the housing contact.If desired, housing can be disposable maybe can be the burning of chemical auxiliary propulsion.

Each projectile can comprise a projectile head and be used for forming the extending apparatus that advances the space to small part.This extending apparatus can comprise a clapboard assembly, and this dividing plate extends back and leans against on the adjacent projectile assembly from projectile head.

This clapboard assembly can pass and advance the space to extend, and therefore is compressed the projectile head of packing into and directly transmits by close adjacent separator assembly.In such configuration, clapboard assembly can the supplemental support extending apparatus, and this extending apparatus can be the thin cylinder bodily form rear portion of projectile head.In addition, this extension apparatus can form with the working seal of the endoporus of housing and contact, and has prevented the leakage of burning from projectile head.

Clapboard assembly can comprise an outward extending stiffening ring, this stiffening ring engages with the thin cylindrical rear portion of malleable projectile head, this thin cylindrical rear portion does not contact with the endoporus sealing of housing, make the filling of axial compression directly between clapboard assembly, transmit like this, therefore avoided the distortion of malleable projectile head.

Complementary wedge-shaped surface can be arranged on clapboard assembly and the projectile head, so projectile head is pushed with the housing endoporus in response to the axial compressive force between baffle plate device and the projectile head and engages.In such layout, projectile head and clapboard assembly can be loaded into gun barrel, after this, produce axial displacement to guarantee the good sealing between projectile head and the gun barrel.Suitable extension apparatus is pushed with the endoporus of gun barrel and engages.

Projectile head can be made the aperture of a taper in rearward end, pack into the tapered plug of a complementation of this aperture, this tapered plug is arranged on the leading section of clapboard assembly, wherein, projectile head produces a rapid expansive force with relative moving axially between the complementary tapered plug, and this expansive force acts on projectile head.

Housing can be that the endoporus of nonmetal and housing can comprise groove, and this groove can hold apparatus to cause bursting whole or in part.In this configuration, housing includes electric conductor, and this electric conductor is convenient to the electrical connection between control device and the apparatus to cause bursting.This configuration can be used for any housing assembly, and this housing has limited emission lifetime, and therefore apparatus to cause bursting and control line can make an integral body with housing.

Cartridge clip can be included in the aperture on the housing selectively, and apparatus to cause bursting is arranged in the outside and the close aperture of housing.Housing can by nonmetallic shell around, this shell can form sleeve, this sleeve can comprise the groove that is suitable for holding apparatus to cause bursting.This shell also can comprise electric conductor, and this electric conductor is convenient to being electrically connected between control device and the apparatus to cause bursting.This shell can be made with the form of superimposed plastic casing.This plastic casing can comprise the superimposed printed circuit that is used for apparatus to cause bursting.

This cartridge clip can have adjacent projectile separated from one another, and keeps certain interval by the positioner that separates with projectile, and each projectile can comprise that one is used for forming with the endoporus of housing the expandable sealing device of working seal.This positioner can be the propellant charge between the adjacent projectile, and sealing device is preferably in and comprises a skirt section on each projectile, and when being condition with the inner housing filling, outwards expand in this skirt section.The filling of this inner housing can be between the projectile installation period or the filling back use, as reinforcing projectile formation and propellant charge, maybe can realize the emission of outside projectile and specific adjacent projectile by tamping.

The rearward end of projectile can comprise a skirt section, groove that inwardly dwindles of this coiled, as the groove or the similar groove of cone-shaped groove or part circular, enter this groove propellant charge portion extension and center on this groove, the motion backward of projectile causes the rapid expansion in projectile skirt section.This motion backward can produce by the mode of compression, and this compression causes that projectile moves along the wedge shape backward of the leading section of propellant charge, can take place with the form that metal flows from big relatively front portion to its less skirt section of projectile.

Selectable, projectile can provide circular seal flange or the ring of dispersing backward, when projectile moves backward, and this circular seal flange or hoop rear-inclined and endoporus sealed engagement.In addition, sealing can work by the housing that projectile is inserted heating, and the housing of this heating is contracted to the corresponding sealing of projectile.Projectile can comprise the hard core by the propellant charge location, this hard core can be molded around the hard core simultaneously with deformable ring portion, form a projectile, this projectile depends on and is used for centering on the outwards endoporus formation sealed engagement of the mobile and housing of the metal of expansion of hard portion between projectile head and the afterbody.

This projectile assembly can comprise an expansion reference surface backward, and this reference surface supports sealing ring in its vicinity, and when projectile passes housing and travels forward, is suitable for the rapid sealed engagement of endoporus with housing.In such configuration, preferably propellant charge has a columniform front portion, and this front portion is near the planar end surface of projectile.

This projectile can be suitable for use in sealing and/or be positioned in the circular groove, or by the annular relief of endoporus or in the reflex groove of endoporus, and can comprise a metal shell packing at least in the outer end of projectile.Projectile can provide contractile circular locating ring, and this locating ring extends out in the annular groove of housing, in projectile launch when it freely passes through gun barrel, this circle locating ring withdrawal.

Be used for propellant charge electronics that order causes barrel assembly and ignite and to comprise that preferably the detonator signal of passing the projectile that piles up by transmission causes the step of anterior propellant charge, and prepare the next propellant charge that drives by next detonator signal by the initiation of anterior propellant charge.Suitable is that all propellant charges inwardly take out from the end of the housing of filling by insert the corresponding insulation fuse between the electric contact of normally closing.

Such ignition can be attainable electronics, or ignites the method for the emission pin type can adopt prior art, as by adopting central authorities' emission trigger to cause outmost projectile, and controls follow-up ignition, makes follow-up projectile sequential blasting.This can by burning gases backward leakage or the burning of the fuse formation of the extension of control by projectile realize.

In another form, it is electronically controlled igniting corresponding to propellant charge, and propellant charge has corresponding trigger, and this trigger is ignited by special detonator signal.For example, trigger in the propellant charge that piles up can sequence order, be used for increase igniting needed pulse width, so Electronic Control can send selectively and increased the ignition of pulse width pulse, in selected time sequencing, sequentially cause propellant charge.Yet preferably propellant charge is ignited by the signal of setting pulse width, and the propellant charge of the next pulsed drive of being sent by the next one is prepared in the burning of front propellant charge.

In such embodiments, preferably all propellant charges are removed by the insulation fuse that is inserted in accordingly between the contact of normally closing from the inside of the gun barrel of filling, when suitable detonator signal transmission, this fuse sets burning to contact for and cuts out, and each insulation fuse opens to corresponding anterior propellant charge, is used to cause propellant charge.

The trigger of any prior art can be used for the present invention.The ignition mechanism of prior art can be used.In the ignition mechanism of such prior art, single emission process can be the extruding or the vacuum of single trigger, is used for the emission of the projectile of predetermined quantity.Do not need the trigger of the projectile of the predetermined quantity that is used to launch to remain on vacuum state, at this moment, projectile may be in automatic weapon, as is in the machine gun of automatic mode.Other trigger mechanism can adopt to be provided by the direct initialized single emission process of the trigger of user or long-range driving, and the projectile of emission predetermined quantity.

The predetermined quantity of projectile will depend on the size of target and feature and determine.At this, target is an assailant or a people, and preferably two or more preferably three projectiles are with needed zone in the selected speed hit.Speed can be greater than 10,000/minute, preferably above 20,000/minute.

When pistol supports when being used to launch in common mode, during launching, its gun barrel promotes around user's wrist joint and rotates.We have found for the absorption of common support the pistol of emission recoil, emission rate will provide low-angle separation between the trajectory of the predetermined quantity of launching fast, and between the targeting zone, provide little vertical space equally, especially when the gtoal setting transmitting site.Similarly, when pistol during from the emission of other direction, it hits at interval will be with the angular spread identical with this direction.

For example, have the peashooter that gun barrel is locked on the pistol framework and be in common transmitting site, like this, the recoil of gun barrel directly is passed on the framework, for two projectiles with 22,500/minute emission rate, from the vertical space between the hit area of the transmitting site of distance target 7m about 220mm.When about 45,000/minute emission rate, this branch is decreased to 150mm at interval.

This numerical value that hits at interval also parameter that will be by influencing firearm recoil works.The pistol of big inertia has less angle intervals between trajectory and less projectile hits at interval.The inertia of pistol is influenced by the weight of rifle and influenced by the weight of personnel's arm of ejecting gun.Therefore, the recoil and the use of hitting at interval also by big projectile or big propellant charge increase.The quantity of emission projectile and launch the speed of these quantity projectiles can be chosen, hit at interval to provide needed.

Pistol of the present invention or miniweapon also can be equipped with the recoil reducing mechanism, as the recoil gun barrel.As the result who adopts in the projectile quantity of very two-forty emission of the present invention, alleged two or three can be launched before gun barrel fully recoil takes place and before the recoil of gun barrel is passed to the pistol framework.Under these circumstances, the projectile with single emission process will also can provide enough targets to run through effect along same ballistic flight substantially.Therefore, such pistol can overcome personnel at risk's bodily protection effectively.In most preferred embodiment, pistol can be equipped with the device that is used for selectively engaging and freeing the recoil reducing mechanism, so that can select to hit at interval or operator's employed pattern for needed.

This pistol preferably has the control device that is used to adjust emission rate, so that can automatic setting be suitable for the speed of operator's conditioned disjunction needs.

This pistol also is equipped with the target range detector, this detector and emission rate controller are an integral body, so that emission rate can automatically be adjusted to and be suitable for detection range and for for reaching the needed sniffer that hits various distances at interval, can adopting as the laser distance detector.Control device such as microprocessor also can be provided for selected needed hitting at interval.

On the other hand, the invention belongs to the method for operating of the miniweapon that comprises trigger, described method comprises:

A kind of miniweapon that can launch a plurality of projectiles to target is provided;

The emission rate of the projectile of selected predetermined quantity is to be provided at needed the hitting at interval on the target; And

Driving has the trigger of single emission process.Preferably this method comprises the step that realization is selected, is determined to the distance of target.

This method also comprises the step of the control device that is provided for changing emission rate, if desired, for reaching needed targeting at interval, provide target range sniffer with the distance that is suitable for target of the automatic adjustment emission rate of emission rate controller one.

The detailed description of accompanying drawing

For making the present invention clearer and be committed to practice, below with reference to the accompanying drawing of describing embodiments of the invention, wherein:

Fig. 1 is the schematic diagram according to the pistol of one embodiment of the present of invention;

Fig. 2 has described an alternative embodiment of the invention.

The explanation of most preferred embodiment of the present invention

Pistol 10 shown in Figure 1 has the barrel assembly 11 of a described type and is installed in electronics emission control on the handle 12.With unshowned quantity and the needed error of hitting that is used to control the projectile of emission rate, emission of touch pad adjuster, each projectile is driven by trigger.

Pistol 10 has the distance detector 14 of a suspension, this distance detector 14 has adopted beam of laser bundle 15, and this laser beam 15 ends on the target 16, so that the reading of a definite target range to be provided, be used to adjust emission rate, reach the predetermined error of hitting.

For example in specification, the user who has set gun controller has realized that three are hit, at first and hitting between the setting of last emission be 450mm at interval, with the chest 17 of aiming pistol 10 in target, and when the manual trigger 18 of extruding, target will be shone by laser, so that the distance to target to be provided, and will ignite three emission bullets automatically with 45,000/minute emission rate emission outside at seven meters radiating circuits.Consider when first emission gun barrel will begin to rise, and when second emission, first energy with second combination will increase soaring speed, therefore, when first emission, the perpendicular separation between the 3rd and second will be greater than the perpendicular separation between second and first.This result can provide a favourable perpendicular separation, if perhaps think, preferably the interval of Zeng Jiaing can be by the emission rate to 60 between increasing by second and the 3rd, and 000/minute reduces.

The aiming point that provides on target, first-round hit will be the chest of target 16, subsequently the millisecond in hit upper breast and head.Like this, not only the lethality of each emission process will increase, and the probability of at least one emission bullet hit also will increase.The joint of the upper and lower or side of the barrel assembly 11 that the scope of hitting can be had by the pistol 10 that grips is selected in top, bottom or side and arranges.

Pistol 20 shown in Figure 2 has adopted the blowback gun pipe assembly 21 of described type, if the error of hit area is necessary, and provides the blocking device 22 of the recoil that is used to prevent barrel assembly 21.The recoil effect of barrel assembly 21 is to set for before recoil stops and before recoil makes gun barrel soaring, can launch three with the emission rate between 20,000/minute and 60,000/minute and launch bullets.

Therefore; when pistol is set in the pattern of gun barrel recoil; the effect that the passing through of pistol 20 promotes the single incident of manual trigger 24 will cause the emissions of three emission bullets; the flight of every emission bullet is substantially along identical trajectory; so that on same position, repeat hit, and run through the protection that the single projectile by the pistol emission of prior art can not run through with continuous multiple projectile rapidly.

In the accompanying drawings, show be used for three continuously emission surpass three milliseconds and the blowback gun pipe assembly 21 ignited by single trigger position with respect to gun stock 25.It is contemplated that at this moment, barrel assembly 21 approaches 50mm with recoil.

If the user wishes to adopt pistol shown in Figure 1 20, the locking device of employing locking barrel assembly 21 is to gun stock 25.Rifle 20 also can be equipped with the controller as the target range sniffer of each rifle 10 control device.

Certainly recognize that above-mentioned explanation is undertaken by the mode of description of the invention, and for a person skilled in the art, all modifications and variations drop on all in the scope of broad of the present invention, and protection scope of the present invention is limited by following specification.
