Abstract

(57) [Summary] The small firearm (10) includes a trigger, a barrel (11), and an electronic ignition control unit built in a grip part (12). The barrel section (11) includes a plurality of axially disposed bullets and an independent charge for propelling each bullet. The firearm (10) includes a laser beam (15) ending in the target (16) that provides an instantaneous reading of the target distance to adjust the firing rate to achieve the desired impact spread. The spread of the impact is attributed to the counter-operation of the small arms (10) causing the barrel to rise. A single fire event fires a trigger, causing the firearm (10) to fire a predetermined number of bullets at a selected rate to provide the desired impact spread on the target (16). If the target (16) is a human, typically two or three bullets will be fired, at a rate of 10,000 to 60,000 shots per minute, depending on the distance to the target. .

Description

Detailed Description of the Invention

[0001]   This invention relates to small firearms, and more particularly to personal firearms.

Personal firearms, such as magazine rotary pistols, are carried by military personnel and law enforcement officers for use in emergencies, such as disabling attackers that threaten the life of the gunholder or other life. . Typically, such firearms have poor accuracy and are used only at close range targets. When the target is a human, the user usually fires at the maximum target zone, ie their chest. Weapon accuracy is relatively low,
If the lethality of the fire is uncertain, such a first fire is not sufficient to deter an attacker who continues to pose the threat.

In one aspect of the invention, a handgun has been found that increases the likelihood that an attacker can be stopped with just one shot. In a broader sense, a firearm has now been found that allows multiple bullets to land on a target at selected impact intervals.

According to the present invention, there is provided a firearm capable of firing a plurality of bullets at a target, the firearm including a trigger, and only one shot actuating the trigger, the firearm being desired by the target. A predetermined number of bullets are fired at a velocity selected to provide the impact interval of.

It will be appreciated that the term “firearms” in the context of the present invention includes pistols, rifles, carbines, light machine guns and machine guns. The present invention has particular application to single-shot firearms employed to shoot targets. In the context of light machine guns and machine guns, the present invention has application in use in single fire mode. Hereinafter, the present invention will be described with reference to a pistol, but it is apparent to those skilled in the art that the present invention can be applied to other small firearms.

The present invention allows bullets to be fired in a controlled rapid-fire sequence, providing PCT / AU94 /
Barrels of the general type described and / or illustrated in Applicant's prior international patent applications, including 000012 and PCT / AU96 / 00459, may be utilized. However, other configurations are used to fire bullets, such as by utilizing a double-tap cartridge from a conventional pistol, or by utilizing individual cartridges from each barrel of a pistol with multiple clustered barrels. You may do it.

[0007] In a preferred embodiment, the bullet is an international patent application PCT / AU94 / 001.
24 and may be housed in a cartridge of the type described in PCT / AU96 / 00459. Such cartridges include a shell, a plurality of bullets axially disposed within the shell for operatively sealing engagement with the bore of the tubular shell, and a separate charge for propelling each bullet. Including.

The bullet may be round, conventional or dart-shaped, with its fins biased to stabilize the dart when fired from the barrel, which may be a smooth barrel. You may make it rotate.

The bullet charge may be in the form of a solid block to operably space the bullets within the shell, or the charge may contact pre-positioned electrical contacts associated with the shell. It may be housed in a metal or other rigid container containing an embedded detonator with external contact means adapted to. For example, a detonator is a spring-loaded contact that allows the insertion of a container-loaded explosive into the shell and is retracted so that it pops out into the opening when aligned with the opening in the operable contact with the mating shell contact. May be equipped with. If desired, the shell may be disposable or may chemically assist the combustion of the charge.

Each bullet may include a warhead and expansion means that at least partially define a launch space. The expansion means may include a spacer portion extending rearward from the warhead and in contact with an adjacent bullet portion.

The spacer portion extends through the firing space and the warhead, thereby transmitting the compressive load directly through the adjacent spacer portion in contact. In such a configuration, the spacer portion may add support to the expansion means, which may be the thin cylindrical rear portion of the warhead. Further, the expansion means may form an operative, closed contact with the shell bore to prevent combustion from leaking past the warhead.

The spacer portion is capable of transmitting axial compressive loads directly between the spacer portions, thereby avoiding deformation of the malleable warhead, such that the malleable bullet is in inoperative sealing contact with the bore of the shell. May include a rigid collar extending outwardly to engage the thin cylindrical rear portion of the.

Complementary wedge-shaped surfaces are disposed on the spacer portion and the warhead, respectively, whereby the warhead engages the bore of the shell in response to relative axial compression between the spacer means and the warhead. You may be encouraged. With such a configuration, the warhead and the spacer portion may be loaded into the barrel and then axially displaced to ensure a sufficient seal between the warhead and the barrel. Appropriately, the expansion means is biased into engagement with the barrel bore.

The warhead has a tapered opening at its rear end that receives a complementary tapered insert located at the front end of the spacer portion, and the relative warp between the warhead and the complementary tapered insert. The axial movement causes a radial spreading force on the warhead.

The shell may be non-metallic and the bore of the shell may include recesses that fully or partially accommodate the firing means. In this configuration, the shell contains a conductor that facilitates electrical conduction between the control means and the firing means. This arrangement may be utilized in a disposable shell part having a firing life limit so that the firing means and control wire or wires may be integrally manufactured with the shell.

The cartridge may alternatively include a firing opening in the shell and the firing means is located outside the shell and proximate the opening. The shell may be surrounded by a non-metallic outer shell forming a sleeve that includes a recess adapted to accommodate the firing means. The outer shell may contain an electrical conductor that facilitates electrical conduction between the control means and the firing means. The outer shell may be formed as a laminated plastic shell which may include a printed circuit laminate of the firing means.

The cartridge may have adjacent bullets separated from each other and kept spaced by the positioning means away from the bullets, each bullet forming an operable seal with the bore of the shell. Expandable sealing means may be included. The positioning means may be a propellant charge between adjacent bullets and the sealing means suitably includes a skirt portion on each bullet which expands outwardly when subjected to an in-shell load. In-shell loading is either applied during the loading of the bullet or after loading such as by packing to arrange the columns of the bullet and the propellant charge, or occurs with the firing of an external bullet, and especially with adjacent external bullets.

The rear end of the bullet is a conical or partially spherical recess into which the propellant charge portion extends and into which the bullet skirt radially expands as the bullet moves backwards. A skirt portion may be included around the concave portion that decreases inward.
This backward movement results from the compression resulting from the backward wedge movement of the bullet along the forward portion of the propellant charge resulting from metal flow from the relatively large and heavy forward portion of the bullet to its small and light skirt.

Alternatively, the bullet may include a rear divergent peripheral sealing flange or collar that deforms outwardly for sealing engagement with the bore hole during rearward movement of the bullet. In addition, the sealing may be performed by inserting the bullets into a heated shell that shrinks onto each sealed portion of the bullet. The bullet is positioned by the launch charge,
A head of a bullet having a relatively rigid mandrel portion cooperating with a deformable tubular portion for molding around the mandrel and expanding outwardly about the mandrel portion for sealing engagement with the bore of the shell. An integral bullet may be formed that relies on metal flow between the section and the tail.

The bullet portion supports a sealing collar portion about the rearward-expanding anvil surface adapted to radially expand into sealing engagement with the shell bore during forward movement of the bullet through the shell. May be included. In such an arrangement, the propellant charge preferably has a cylindrical front portion that contacts the flat end surface of the bullet.

The bullet may be fixedly secured and / or positioned in the circumferential groove, at the annular ribs of the bore, or in the rifling groove of the bore, and may include a metal jacket surrounding at least the outer end portion of the bullet. The bullet may include a retractable perimeter ring that expands outward in an annular groove in the shell and retracts into the bullet upon firing to allow the barrel to pass freely.

An electric ignition device that sequentially ignites the propellant charge of the barrel portion ignites the forward-propelled charge by sending an ignition signal through the stacked bullets, and the forward-propelled charge is ignited, and then the subsequent firing. Preferably, the step of preparing the next propellant charge for activation by the signal is ready for ignition. All propellant charge inwardly from the end of a suitably loaded shell is fire ready by the insertion of respective insulating fuzes located between the normally closed electrical contacts.

A central detonator may electrically ignite the propellant charge, or ignite an outermost bullet, and control the resulting ignition to sequentially ignite the propellant charge for the next shot. A conventional firing pin method may be employed, such as by using This may be done by controlling the back leakage of combustion gases, or by controlling the combustion of the fuze rows extending through the bullet.

In another embodiment, the firing is electronically controlled and associated with a detonator that detonates each propellant charge with a unique firing signal. For example, the detonators in the stacked propellant charge may be sequenced to increase pulse width firing conditions, thereby
The electronic controller selectively sends firing pulses that increase the pulse width to sequentially fire the explosive charge in a selected time sequence. However, preferably, the propellant charge fires at the set pulse width signal and the combustion of the forward propellant charge prepares the next propellant charge for firing by the next firing pulse.

Suitably in such an embodiment, all propellant charge from the end of the loaded barrel to the inside is secured by the insertion of respective insulated fuzes located between the normally closed electrical contacts. , These fuzes are set to burn and close the contacts upon the transmission of the appropriate firing signal, and each insulated fuze is opened to its respective forward propellant charge for ignition by it. ing.

Any conventional trigger may be used in the present invention. A conventional trigger mechanism may be used. In such a conventional trigger mechanism, the single firing event may be squeezing or holding the trigger only once for a given number of bullets to be fired. It is not necessary to hold the trigger held down while firing a certain number of bullets as was the case with automatic weapons such as machine guns in automatic mode. Other triggering mechanisms may be employed as long as a single firing event initiated directly or remotely by the user can activate the trigger and fire a predetermined number of bullets.

The predetermined number of bullets depends on the size and nature of the target. If the target is an attacker or human, then preferably two, and more preferably three bullets are fired at a rate selected to provide the target with the desired impact interval. The speed is 10 per minute
Faster than 1,000 shots, preferably more than 20,000.

When supporting a handgun for firing in a conventional manner, the barrel pivots about the user's wrist at the time of firing. Typically, pistols supported in the traditional way of absorbing the recoil of the launch produce small angle deviations between the trajectories of a given number of projectiles when fired at high speeds, and thus, especially when the target is in the firing position. We have found that when close, there is a small vertical spacing between the target impact zones. When the pistol is held horizontally, the impact interval extends horizontally. Similarly, if the pistol is fired from another orientation, its impact spacing will also spread at an angle equal to that orientation.

For example, when firing from a conventional firing position with a small caliber pistol having a barrel locked in the frame of the pistol, the vertical spacing between the impact zones of two bullets fired at a speed of 22,500 rounds per minute. Would be on the order of 220 mm for a target 7 m away from the launch position. This deviation would be reduced to 150 mm at a firing rate of about 45,000 rounds per minute.

Impact distance is provided by a number of parameters that affect the recoil of the pistol. The greater the inertia of the pistol, the smaller the angular spacing between the trajectories and the smaller the impact spacing of the bullets. The inertia of a handgun is also affected by the weight of the gun and the strength and weight of the arm of the person firing the gun. Recoil, or impact spacing, is also increased by the use of more bullets or large amounts of propellant charge. The number of bullets and the rate at which that number of bullets are fired are selected to give the desired impact interval.

The handgun or other firearm of the present invention may incorporate a recoil reduction mechanism, such as a recoil barrel. If a very high rate of fire is employed in the present invention, a large number of, for example, two or two bullets will be present before the barrel completes the recoil motion and before the barrel recoil is transmitted to the frame of the pistol. Is fired. In such a situation, the bullets fired in a single-fire event will follow substantially the same trajectory and the target penetration depth effect will be enhanced. Therefore, such a pistol is effective for a person wearing protective clothing. In a preferred embodiment, the pistol incorporates means for selectively actuating and deactivating the recoil reduction mechanism so that it can be selectively used in either mode intended for desired shock spacing, or penetration depth. Good.

The pistol suitably has control means for adjusting the firing rate so that it can be set automatically or manually to suit the operator's requirements or requirements. The pistol may incorporate controls to select the number of bullets fired in a single fire event.

The pistol incorporates a target distance sensor associated with the firing rate control so that the firing rate can be automatically adjusted to match the detected target distance to achieve the desired target impact interval. Good. Various measuring devices, such as laser rangefinders, that measure the distance to the target may be used. Control means, such as a microprocessor, may be provided to select the desired shock interval.

[0034]   In another aspect, the invention provides a method of operating a firearm used.   Prepare a firearm with a trigger that can fire multiple bullets at the target,   Select the firing speed of a certain number of bullets to give the target the desired impact interval,   Activating a trigger on a single fire event.

This method further provides a control means for changing the firing rate, and if necessary, a firing rate control unit capable of automatically adjusting the firing rate in accordance with the detected target distance to achieve a desired target interval. And a step of providing a target distance detecting means related to the above. In order to more easily understand and practice the present invention, reference is made to the accompanying figures which illustrate exemplary embodiments of the invention.

The pistol 10 illustrated in FIG. 1 includes a barrel 11 of the type described, and a not-shown touch pad for controlling the firing speed, the number of bullets fired at each trigger operation, and the desired spread of impact. Along with the adjuster, it has an electronic emission control unit built in the grip 12.

The pistol 10 also utilizes a pendant distance utilizing a laser beam 15 terminating at the target 16 to provide an instantaneous reading of the target distance for adjusting the firing rate to achieve a preset impact spread. It has a detection device 14.

For example, in the figure, the impact deviation between the first and last fired bullets is 450 mm.
A user who has set the gun control unit so that the number of consecutive shots of
Aim the pistol 10 at 7, and when the trigger 18 is squeezed, a laser beam is applied to the target to measure the distance to the target.
Automatically fire three external bullets at a speed of 5,000. When the first bullet is fired, the barrel begins to rise, and when the second bullet is fired, the combined energy of the first and second bullets is combined to increase the rate of rise, so the third bullet is fired. When done, the third
It is considered that the vertical deviation between the bullet and the second bullet is larger than the vertical deviation between the second bullet and the first bullet. If this result is considered to be an advantage of the vertical deviation, or if it is considered preferable, the increasing deviation is set to the firing speed between the second and third shots, for example, 6
It may be reduced by increasing it to 10,000 rpm.

When the aim is targeted, the first impact is on the chest of the target 16, followed by impacts on the upper chest and head at intervals of a few milliseconds. Therefore, either the lethality rate per firing event is increased or the chance of at least one bullet hitting the target is increased. The spread of impact may be in an up, down or sideways array selected by holding the pistol 10 with its barrel 19 above, below, lateral left or right.

The pistol 20 illustrated in FIG. 2 utilizes a recoil barrel 21 of the type described which is provided with latching means 22 for preventing recoil of the barrel when a widening impact zone is required. The reaction part of the barrel part 21 is designed so that three bullets can be fired at a high speed of 20,000 to 30,000 per minute before the reaction part is finished, and therefore before the reaction force causes the barrel to rise. Is set to.

Therefore, when the pistol is set to the barrel recoil mode, the single firing event actuation of the pistol 20 by pulling the trigger 24 causes each bullet to move substantially along the same trajectory.
Since it will be a rapid fire of bullets, it will repeatedly and rapidly fire at the same position so that the protective clothing that can not be penetrated by a single bullet fired from a conventional pistol can be penetrated by those bullets Can be landed on.

In the figure, the position of the recoiled barrel 21 with respect to the stock 25 is shown for a triple firing which occurs in a time of about 3 milliseconds and is actuated by a single trigger operation. The barrel 21 is then considered to recoil by approximately 50 mm.

When the user wants to use the gun 20 in the mode shown in FIG. 1, the barrel portion 21 is locked to the stock 25 using the latch means. The gun 20 may incorporate not only the target distance detecting means but also a control device like the gun 10.

The above description is given as an illustration of the present invention, and all modifications and variations to them that would be obvious to those skilled in the art depart from the broad scope of the invention as detailed herein. It will be understood that it is not thought to be done.

The pistol 10 also utilizes a laser beam 15 terminating at the target 16 to provide an instantaneous reading of the target distance for adjusting the firing rate to achieve a preset impact spread. It has a detection device 14.

For example, in the figure, the impact deviation between the first and last fired bullets is 450 mm.
A user who has set the gun control unit so that the number of consecutive shots of
Aim the pistol 10 at 7, and when squeezing the manual trigger 18, measure the distance to the target by applying a laser beam to the target, and at 7 meters, the firing circuit 3 shots at a speed of 45,000 shots per minute Automatically fire external bullets. When the first bullet is fired, the barrel begins to rise, and when the second bullet is fired, the combined energy of the first and second bullets is combined to increase the rate of rise, so the third bullet is fired. When done,
It is considered that the vertical deviation between the third bullet and the second bullet is larger than the vertical deviation between the second bullet and the first bullet. If this result is considered to be an advantage of vertical deviation, or if it is considered preferable, even if the increasing deviation is reduced by increasing the firing rate between the second and third shots to, for example, 60,000 rpm. Good.

When the aim is targeted, the first impact is on the chest of the target 16, followed by impacts to the upper chest and head at intervals of a few milliseconds. Therefore, either the lethality rate per firing event is increased or the chance of at least one bullet hitting the target is increased. The spread of impact may be in an up, down or sideways array selected by holding the pistol 10 with its barrel 19 above, below, lateral left or right.

The pistol 20 illustrated in FIG. 2 utilizes a recoil barrel 21 with latching means 22 of the type described, which prevents recoil of the barrel when an impact zone spread is required. The reaction part of the barrel part 21 is designed so that three bullets can be fired at a high speed of 20,000 to 30,000 per minute before the reaction part is finished, and therefore before the reaction force causes the barrel to rise. Is set to.

Therefore, when the pistol is set to the barrel recoil mode, the single firing event actuation of the pistol 20 by pulling the manual trigger 24 results in a series of three shots with each bullet moving substantially along the same trajectory. Therefore, it is possible to hit the target repeatedly and at the same position in the same position so that the protective clothing that can not be penetrated by a single shot fired from a conventional pistol can be penetrated by those bullets. it can.

In the figure, the position of the recoiled barrel 21 with respect to the stock 25 is shown for a triple firing which occurs in a time of about 3 milliseconds and is actuated by a single trigger operation. The barrel 21 is then considered to recoil by approximately 50 mm.

When the user wants to use the gun 20 in the mode shown in FIG. 1, the barrel portion 21 is locked to the stock 25 by using the latch means. The gun 20 may incorporate not only the target distance detecting means but also a control device like the gun 10.

The above description is given as an illustration of the present invention, and all modifications and variations to them that would be obvious to a person skilled in the art are of the invention as detailed herein in the claims . It will be appreciated that it is not considered to be outside the broad scope.
