Description

Technical field

The present invention relates to firearms for firing shells of various calibers. In particular, the first objective of the present invention is the conversion of a barrel of a large caliber firearm into a barrel of a smaller caliber using an insert into a barrel of a larger caliber.

The second objective of the present invention is the loading of shells into weapons such as firearms and large-caliber weapons. The second objective of the invention is specifically implemented in weapons, including barrels, in each of which many shells are stacked along the axis of the barrel along with individual selectively flammable propellant charges for moving the shells along the bore and subsequently ejecting them through the barrel muzzle. Such trunks will hereinafter be called trunks of the described type.

BACKGROUND OF THE INVENTION

Previous attempts to reduce the caliber of conventional weapons were significantly hindered on the mechanical side, in particular with respect to the breech of the weapon, which required the mechanical supply of shells and the safe attachment of additional trunks to an existing barrel.

Additional barrels, designed to increase firepower and which include weapons such as an underbarrel grenade launcher for launching grenades, have limited operational capabilities due to the complex and / or expensive devices currently available for quick reloading when using weapons in combat.

SUMMARY OF THE INVENTION

Subject of invention

An object of the present invention is to provide some weapon designs that provide a device and method for easily and conveniently converting large-caliber firearms into smaller-caliber weapons.

The aim of some variants of the invention is to create an assembly of trunks containing shells, which can be used to quickly reload weapons having a barrel of the described type.

Disclosure of invention

In order to achieve the first objective, the present invention provides a barrel or barrel assembly that is inserted into the mother barrel of the weapon, wherein said barrel assembly has a plurality of shells arranged along the axis of at least one barrel with separate selectively flammable propellant charges to advance the shells, at least one trunk in which said trunk assembly includes means for attaching to the mother trunk. In addition, the present invention provides a method for converting a larger caliber of a weapon to a smaller caliber, comprising the step of inserting an assembly of barrels having a plurality of shells arranged axially in at least one barrel and provided with separate selectively flammable propellant charges to advance the shells of at least at least one trunk in which said trunk assembly includes attachment means with a mother trunk.

In one embodiment, to achieve the first objective of the invention, the barrel assembly may comprise a single barrel. In other embodiments, the trunk assembly may include a group of aligned trunks, whereby the group of trunks may constitute a compact assembly that is inserted into the mother trunk. Where a group of trunks is used in the assembly of trunks, this assembly of trunks preferably includes a housing in which the trunks are placed. The body can be made in one piece with the trunks. In this form, the hull and trunks can be a disposable unit, which is removed after all shells are ejected from it. Alternatively, the barrel assembly can be reloaded with shells and reused.

The housing can be formed separately from the trunks, and the trunks can be inserted into the housing before the housing is inserted into the mother trunk. In this form, the trunks can be inserted into the housing, which is located in the mother trunk or into the housing removed from the mother trunk.

The housing may be made of any suitable material. It is preferable to make the casing of a material with sufficient structural strength so that the trunks are effectively held in position when fired, but not so hard and rigid that the mother barrel could be damaged when the trunk assembly is reinserted into the mother barrel and then removed.

The mother trunk can be of any type convenient for use. For example, the mother barrel may be in the form of a unit of conventional weapons used by infantry, and the insertion of the barrel assembly into the weapon may be provided by an electronic fire control system. The mother barrel can be serviced electronically by the weapons used.

In one embodiment of the first objective of the invention, an assembly of full-length trunks is provided that is inserted into the mother barrel from the muzzle. This option, in particular, is applicable to conventional weapons, which ensures ready access without reconstruction of the existing barrel. In this embodiment, the assembly of trunks can be inserted through the muzzle of the mother trunk and held in it. The trunk assembly includes means for interacting with a modular cut of the mother trunk and may also include means for attaching said trunk assembly to the mother trunk. However, there is an alternative weapon in which the mother barrel consists of two sections and, therefore, access to the barrel of a separate section occurs with a partial disassembly of the existing weapon. In this embodiment, the barrel assembly may be inserted in two parts. The first or front section of the trunk can be inserted into the mother trunk through the muzzle of the mother trunk. This front section of the barrel is actually a continuation of the barrel and does not contain any shells. The second or rear section of the barrel contains shells and can be inserted through the breech of the mother trunk and connected to the front section of the barrel to form a complete assembly of trunks with shells and firing means.

Trunk assemblies can be inserted from the front or back of the mother trunk. Depending on the configuration, the trunk assembly may be connected to the mother trunk channel by a plurality of individual elements or tabs that extend from the trunk assembly to provide a connection within the mother trunk channel. These spaced sections may have the same diameter as the diameter of the mother trunk channel. Such individual sections may be made of metal or insulating material and may facilitate the operation of the firing system. The orientation of the assembly of the trunks can be fixed with keys located at the muzzle, breech, or both of these parts of the mother trunk. Where a group of trunks is included in a single trunk assembly, the housing preferably includes a plurality of separate sections for connection to a mother trunk channel.

The barrel assembly, which contains one or more trunks, may include an electronic installation system that is wired to a firing mechanism outside the mother barrel. In one embodiment, the trigger of the maternal weapon can be adapted to fire shells fired from the assembly of trunks. Where separate sections are used to connect to the channel of the mother trunk, the wires required for the trunk assembly to work can be routed through the free space created with this configuration and can exit the mother trunk either through the muzzle or through the breech. Preferably, the firing mechanism would include conductors for signaling, entering through the rear section of the mother trunk.

To achieve the second objective of the present invention, the weapon has an assembly of trunks for loading a weapon having an elongation of the barrel, in which the specified assembly of trunks has a lot of shells located along the axis in the barrel, and associated with individual selectively flammable propellant charges to advance along the bore, barrel-mounted weapons include a barrel extension tool. In accordance with the stated object of the present invention, there is provided a method for loading a weapon having an extension of the barrel, comprising the steps of connecting the barrel assembly to a plurality of shells, with the extension of the barrel, wherein said plurality of shells are located axially in the barrel channel and are associated with individual selectively flammable propelling charges shells along the bore, while the specified assembly of the trunks includes a means for connecting with the extension of the barrel.

In a preferred embodiment, the barrel extension means has a beveled front trunk assembly section that comes into contact with a corresponding surface on the barrel extension. Using a beveled barrel extension means allows you to insert the barrel assembly into the barrel extension obliquely and then align the barrel with the barrel extension, followed by fixing the assembly in position. Preferably, the barrel assembly fits snugly into the barrel extension. The assembly of the trunks and the extension of the barrel, respectively, are fastened by a fixation system for removable fastening of the trunk assembly with extension.

Alternatively, the barrel extension tool may include a stepped section that fits into the corresponding stepped section in the barrel extension. In another embodiment, the barrel assembly is simply attached to the barrel extension. At the junction between the barrel assembly and the barrel extension, a sleeve may be provided that holds the barrel assembly in position with respect to the barrel extension.

In one embodiment, to ensure the second objective of the invention, the assembly of trunks containing shells may have a lever that allows the placement and fixation of this section with the main section of the barrel in the weapon system. During transportation and storage of the barrel section, this lever can be folded and forms a small profile along the barrel section. When the projectile section of the barrel is attached to the weapon system, the lever can be raised to assist in the operation of placing and fixing the section of the barrel similar to the action of the shutter of a conventional rifle. An annular locking device on the barrel assembly can also be used to orient and fix the barrel section. In a preferred configuration, when the lever is moved to the locked position, the key mechanism also moves to this position.

In another embodiment of the invention, the assembly of the trunks is introduced obliquely into the barrel extension and then pushed down until it is locked by the locking mechanism. The same mechanical locking system can act as the ejection system of the used barrel assembly.

In yet another embodiment, to provide a second objective of the invention, one or more spare barrel assemblies are used containing shells that can be placed on weapons, usually from below. When the last projectile is fired from an existing barrel assembly, this used barrel assembly can be thrown away automatically, and the spare barrel assembly is automatically inserted and locked in position ready to receive a new firing command.

The present invention has particular application in barrel assemblies, which are described in the earlier filed international patent applications PCT / AU 94/00124 and PCT / AU 96/00459 by the author of this application. Such barrel assemblies include a barrel, a plurality of shells arranged axially in the barrel to create close operational contact with the barrel channel, and individual propellant charges that propel the corresponding shells along the barrel channel and release them sequentially through the barrel muzzle.

The shells can be round, ordinary shape or made in the form of an arrow, mainly spherical or any other convenient shape. The projectile may also include stabilizers, which can be offset to create a stabilization rotation, as the arrow can be ejected from a smooth-bore firearm.

The propellant charge can be made in the form of a solid block, and such charges are quickly placed between individual shells in the barrel. Alternatively, the propellant charge may be enclosed in a metal or other solid body and may include an enclosed capsule having external contact means for connecting to an electrical contact previously mounted on the barrel.

For example, the capsule could be provided with a spring contact, which can be pulled out to insert the warhead in the shell into the barrel and then enter the barrel hole after aligning with this hole for working contact with the barrel barrel contact. If desired, the outer shell may be sacrificed or chemically facilitate the combustion of the warhead. In addition, a set of embedded and / or individual charges in the shell and shells can be prepared in advance for quick reloading of the barrel.

Each projectile may include a projectile head and an elongated end, at least to partially create space for a propellant charge. The extension may include a gasket assembly that extends back from the projectile head and abuts against an adjacent projectile assembly. Such an elongated end may assist in fixing the projectile in the barrel and hold the shells in the barrel when the front charge is ignited.

The gasket assembly can pass through the propellant charge space and the projectile head, whereby the compression forces are transmitted directly through adjacent adjacent gasket assemblies. In this configuration, the gasket assembly can enhance the fixation of the projectile and elongated end. The elongated end may be a thin cylindrical rear of the projectile head. In addition, the elongated end can create tight operational contact with the bore to prevent hot combustion products from leaking past the projectile head.

The gasket assembly may include a rigid cage, which expands outward and comes into contact with the thin cylindrical back of the soft shell head, creating an operational seal with the bore. Thus, axial compressive loads are transferred directly between the gasket assemblies, thus eliminating the deformation of the soft projectile head.

An additional jamming surface may be located on the gasket assembly and the projectile head, respectively, whereby the projectile head comes into close contact with the barrel channel in response to relative axial compression between the gasket assemblies and the projectile head. In such a device, the projectile head and gasket assembly can be loaded into the barrel and after creating axial displacement during the propellant explosion, they guarantee a good seal between the projectile head and the barrel. Accordingly, the elongated end may come into contact with the bore.

The projectile head can define a conical hole at its rear end, which includes an additional conical plug located at the front end of the gasket assembly. The relative axial movement between the projectile head and the additional conical plug creates an expansion force applied to the projectile head.

The barrel may be non-metallic, and the barrel channel may have grooves in which the ignition means can be partially or completely placed. In this configuration, the barrel may include electrical conductors that provide electrical communication between the monitoring means and the ignition means. This configuration can be used for disposable barrel assemblies that have a limited life, and wired ignition and control tools can be made integral with the barrel.

The barrel assembly may alternatively include ignition holes formed in the barrel and ignition means outside the barrel near these holes. The barrel may be surrounded by a non-metallic outer casing, which may include recesses designed to accommodate the means of ignition. The outer casing may also include electrical conductors that facilitate electrical communication between the controls and the ignition means. The outer casing may be made in the form of a multilayer element of plastic, which may include a layer with a printed circuit for controlling the means of ignition.

The rear end of the projectile may include a skirt around a tapering inward recess, such as a conical recess or a partially spherical recess or the like, which includes part of the propellant charge, and moving the projectile backward causes a radial expansion of the projectile skirt. This backward movement can be caused by compression during jamming of the projectile along the front of the propellant charge as a result of the flow of metal from the relatively massive front of the projectile to its less massive part of the skirt.

Alternatively, the projectile can be equipped with a diverging backward sealing flange or ring, which bends outward for tight contact with the bore when the projectile moves backward. In addition, compaction can be achieved by inserting shells into a heated barrel, which compresses when cooled and provides compaction of the corresponding parts. The projectile may contain a relatively hard part of the mandrel, which interacts with the deformable annular part and which can be pressed onto the mandrel to form a single projectile, while the material of the annular part is deformed to expand outward from the mandrel and is pressed against the walls of the barrel bore.

The projectile assembly may include a tapered outward wedge-shaped surface on which an o-ring rests, which expands radially outward to close contact with the barrel channel when the projectile moves backward through the barrel. In such a configuration, it is preferable that the propellant charge would have a cylindrical front portion that borders a flat end surface of the projectile.

The shells can be placed in the barrel with the creation of contact with spiral grooves and / or ribs in the channel of the barrel and may include a metal casing containing at least the outer end part of the projectile. The projectile can be equipped with compressible outer rings or bands that fit into the grooves of the barrel and into the projectile to ensure its free passage through the barrel.

The electrical ignition during sequential ignition of the propellant charges in the barrel may preferably include the stage of ignition of the propellant charge by sending an ignition signal through the projectiles stacked in the column. In this case, the ignition of the front propellant charge can prepare the next propellant charge, which is activated when the next ignition signal arrives. Moreover, all warheads inside the barrel, starting from the end of a charged barrel, are discharged using a safety insulating insert placed between normally closed electrical contacts. These insulating inserts burn out and provide contact closure when an appropriate trigger signal is applied, while each insulating insert is open for a corresponding forward propellant charge to ignite it.

Ignition of the propellant charge can be carried out electrically or conventional methods such as the firing pin of the central capsule fuse, igniting the most distant charge and causing sequential ignition of the propellant charges of subsequent projectiles, can be used to ignite. This can be done by feeding back hot combustion products or by controlled burning of insulating inserts between shells laid in the barrel.

In another embodiment, the ignition process is electronically controlled associated with the corresponding propellant charges with fuses that are activated by the corresponding ignition signals. For example, the fuses in the propellant stacked in the column can be ordered to fulfill the requirements for increasing the ignition pulse width, whereby the electronic control means can selectively send ignition pulses of a certain width to ignite the propelling charges sequentially in a specific time order. However, it is preferable that the propellant charges be ignited by a series of pulses of different widths with the ignition of the first propellant charge of the weapon to ignite the subsequent propellant charge with the next pulse given.

Many shells can be fired simultaneously or in quick succession or in response to re-activating the trigger, for example, by pressing the trigger with an arrow. For example, in such devices, an electric signal can be supplied from the outside of the barrel either through shells attached to each other through which an electric circuit is carried inside the barrel, or through the electrical contact of shells with each other to create an electric fire control circuit.

The barrel assembly can be inserted into various weapons. In one embodiment, the barrel assembly of the present invention may be inserted into a firearm such as a pistol, rifle or other small firearm. In another embodiment, the barrel assembly of the present invention can be inserted into large-caliber artillery equipment. The present invention also covers all types of weapons, which includes the barrel assembly described above. The weapons of the present invention may also include stocks, handles, optical sights, mounts, etc.

DESCRIPTION OF SOME OPTIONS OF THE INVENTION

Figure 1 shows a rifle 10 containing a box 11, the primary barrel 12 and the upper barrel 13.

In FIG. 2, it can be seen that inside the upper barrel 13 there is a front extension 44 of the barrel insert along with the rear section of the barrel, which form the barrel assembly 15 a, in which the projectiles 16 are laid along the axis.

Additional or spare shafts assembly 15b and 15c are located in the box 11 of the rifle 10. The spare shafts assembly are arranged so that they are aligned along the barrel insert 14 as soon as the first barrel 15a releases all its shells 16. If necessary, the supply of spare shafts can occur automatically after the ejection of the used barrel assembly 15.

The perspective view of FIG. 3 shows the front extension 44 of the insert of the barrel 14 in the extended position (rod of the upper barrel 13). The barrel 15a is held in place by a casing 19, which serves to support the barrel 15a in an axially aligned state with the barrel insert 14. The barrel assembly also includes a beveled front end 17 for quick connection with an additional rear end 18 of the barrel insert 14, as shown in FIG. 2 . The stock may be provided with a spring to move the assembly of the barrel 15a forward and create tight contact with the insert of the barrel 14.

Figure 4 shows the Steer rifle 20 having a 40-mm upper barrel 21, which includes the insert of the barrel 22 with a diameter of 20 mm. The insert of the barrel 22 has an extension of the front barrel 23 with a muzzle 24.

Returning to a partial section of the rifle 20 in FIG. 5, we see that the extension of the barrel 23 includes fasteners in the form of flanges 25 located at some distance from each other along the extension and used to connect with the channel of the mother barrel 21. The barrel assembly 26, containing shells laid along the axis 27, is inserted into the breech of the barrel 21 under the casing 28, thus forming the rear section of the barrel. The barrel 26 also includes flanges 25 for supporting the barrel assembly together with electronic firing means (not shown).

The electronic firing means may be a corresponding electronic device with recesses provided in the barrel 26, in which the ignition means is located, or this means is integrated in the barrel, as described in the previously filed international patent application of the present applicant. In this configuration, the 40 mm barrel 21 can be converted into a 20 mm electronically controlled weapon.

The Steer rifle 30 shown in FIGS. 7, 8 and 9 includes a front section of the upper barrel 31 and a section of the rear barrel 32. The rear assembly of the shafts 33 of the rear section contains a number of shells 35 and is equipped with a beveled front end 34 for quick connection with the rear end of the barrel extension 31. The 40-mm upper barrel is placed in the casing 37, which corresponds to the barrel assembly barrel 33 and contains shells 35.

10, 11 and 12 show an FM-FMC 40 rifle with a 40 mm upper barrel 41. The 40 mm upper barrel consists of two parts, a muzzle 42 and / or extension 43, and is mounted in the housing 44, as shown on Fig. The rear section of the barrel, containing the assembly of trunks 45 with shells 46, has a beveled front end 47, which provides quick connection with the additional rear end 48 of the extension of the barrel 43. The casing 49 closes the assembly of trunks and ensures its desired position in the rifle 40.

INDUSTRIAL APPLICATION

The use of the assembly of trunks inserted into the mother barrel in accordance with the first objective of the invention provides the versatility of a weapon that can fire shells of various types and calibers, thus expanding the capabilities of an individual weapon when used in various combat conditions.

The relatively simple assembly of the barrel, which is inserted into the existing mother barrel, provides significant advantages in terms of reliability, suitability and machinability, especially in the manufacturing process, to expand the operational ability of a rifle or other weapon.

Achieving the second objective of the invention allows the shooter to charge the barrel assembly with shells located in the attached section of the weapon barrel. After the release of all the shells, the barrel assembly can be removed, and the new barrel assembly with shells can be quickly attached to the weapon system.

If it is possible to use the rear section, also containing shells and acting as part of the barrel, the weight of an unloaded weapon can be reduced due to the weight in the section with shells. By preloading shells of a separate section of the barrel, quality control can be improved. Transportation and storage of shells and warheads are also greatly facilitated.

In one specific application, a separate grenade launcher is used on infantry weapons, which, as a rule, are mounted under the main barrel. This grenade launcher is replaced by an electronically controlled barrel containing 5 or 6 shells, which have a higher velocity at the muzzle end. A conventional grenade launcher requires reloading after each use, which leads to a reorientation of the target and elimination of the aiming error after the previous shot. The invention reduces the number of reloads, provides improved hit accuracy and a better solution to the ballistic problem when used, since here, with each shot, only adjustment is required to eliminate the error of aiming the weapon, which is constantly aimed at the target. Most importantly, the weapon can more quickly and accurately direct all firepower to the target in the critical first 10 seconds in a battle with enemy forces.

It should be understood that the above description is only an example of the implementation of several variants of the invention and that all modifications can be made by changing the individual nodes of the present invention, which is obvious to experts in this field, and such changes do not go beyond the scope of the invention defined by the following claims.
