Description

The invention is called "Firearms with the barrel forward."

The invention relates to firearms: submachine gun, PDW (Yandex-PDW weapon), “machine gun”, carbine, rifle, machine gun, grenade launcher, gun.

The weapon consists of a barrel with a bolt, rammer, copier, bed, reflector, trigger, cocking handle, delay mechanism for protracted shots, gas engine, springs, butt.

The objective of the invention is the creation of weapons providing the technical result: MAXIMUM REDUCTION OF WEAPON DIMENSIONS when firing powerful cartridges, with a long barrel, and high: reliability, manufacturability, safety, accuracy and accuracy of all types of fire, with minimal impact.

The closest example of a weapon is the latest "machine gun" X95 Israel (Yandex - "machine gun" X95 Israel), which with a total length of 580 mm. Guns, has a barrel of only 330 mm., Which is unacceptable for military units, and there is no full two-way shooting and for firing on the left you need to reconfigure the “machine gun” for a long time, which is completely impossible in battle. In the version of the submachine gun made a free shutter with all its disadvantages. Heavy and inertial descent is an UNSOLVABLE PROBLEM of all firearms according to the bullpup system. The proposed weapon has a bulpap system and instead of a complex one with large dimensions and tight tolerances, the shutter with a long stroke has a compact, lightweight and simple shutter with a short stroke, and the barrel with a forward stroke, which significantly reduces the dimensions of the weapon and, as a result, reduces the weight of the weapon.

Disclosure of Invention

I’ll start with a description of the barrel locking system, we’re doing it like a nominal Lynx pump action shotgun (Yandex-shotgun Lynx) - also two hooks located diametrically against each other on the bolt, only without springs. After the shot (option 1 of FIG. 12), the moving parts: the shutter 39 coupled to the barrel 1, move forward (which will be described below) and when the shutter mirror 39a arrives on the G-D line of FIG. 12 the round protrusion 64 of FIG. 12 following strictly parallel to the axis of the bore 1 of FIG. 12 along the groove of the stationary copier 63 of FIG. 12 (in the upper drawing, the groove is indicated by a dashed line) finds the groove rotated at an angle to, for example, 137 ° of FIG. 12 and the hook 56 of FIG. 12 will begin to rotate on axis 57 of FIG. 12 outwardly disengaging as a large tooth 59 of FIG. 13 and the small tooth 62 of FIG. 12 and on the way E = 4 mm. between lines GG of FIG. 13 and BB of FIG. 13 the hook 56 of FIG. 13 disengages from the barrel 1 of FIG. 13, the second hook works similarly, only without a small tooth, at the same time the shutter mirror 39a of FIG. 13 with focus 38 of FIG. 13, on line BB of FIG. 13 will stop at M.T. FIG. 13, and the barrel 1 of FIG. 13 by inertia will go forward. During the course of the barrel 1 of FIG. 13 back, it engages with the shutter 39 of FIG. 13 in reverse order. Shown are 2 hook options, option I of FIG. 12 is preferable since the jumper 58 of FIG. 13 makes the hook completely unbendable, and the small tooth 62 of FIG. 12 with self-tightening elements, increases the area of engagement and, accordingly, more reliability and resource of parts, easier option II of FIG. 12 copy I of FIG. 12 without a small tooth 62 of FIG. 12. The course of the hooks is extremely short and simple, there is simply nothing to break and wedge, there are options for hooks without axes in tight tolerances, and in the form of detachable liners (separate patent), there are options for locking the barrel with transverse wedges (separate patents). This system is especially rational for submachine guns and PDW. Now the power system. After the shutter mirror 39a of FIG. 13 will stop at M.T. FIG. 13 (the delay mechanism 18 will be pressed down after the shot and will not interfere with the forward motion of the barrel 1, as will be shown below) the barrel 1 of FIG. 10 disengaged from the shutter 39 of FIG. 10 by inertia will continue to move forward, together with the barrel 1 of FIG. 10 by means of the spike 53 of FIG. 10 moves forward and the copier 48 of FIG. 10, the round protrusion 52 of FIG. 10 (you can put a small bearing or roller) moves along the curve of the groove 49 of FIG. 9 lowering and raising the rammer 46 of FIG. 10 up and down the distance D of FIG. 9 for example 14 mm: On the way 29 mm. (cylindrical part of the sleeve of the Grendel cartridge) groove 49 of FIG. 9 is a straight line parallel to the axis of the bore 1 of the barrel 1 and when passing this section with the protrusion 52, the rammer 46 is in place in the upper position, with the further movement of the copier 48 forward, the protrusion 52 of FIG. 10 smoothly as if enveloping the head of cartridge II of FIG. 10 goes down, rammer 46, too, at this time the forward barrel 1 of FIG. 10 with a visor 54 of FIG. 11 passes as closely as possible around the head of the lowering cartridge II of FIG. 10 and the tip of the bullet passes in the neckline of the visor 54 of FIG. 11. Upon reaching the barrel 1 extreme forward position, compressing the return spring 27 of FIG. 6 with a cross-shaped stop 30 of FIG. 6 and finally compressing the buffer spring 23 of FIG. 6 to the right with a cross-shaped stop 29 of FIG. 6, rammer 46 of FIG. 10 is lowered by a distance D of FIG. 9 by shifting the sleeve I of FIG. 10 and cartridge II of FIG. 10 down the T-rail 51 of FIG. 10, it holds the sleeve I of FIG. 9 uniformly on both sides without small and unreliable moving parts and springs, simply and reliably acting as an ejector, in contrast to the cantilever and unreliable ejector of the classics, while the sleeve I of FIG. 10 lies on the bed 45 of FIG. 10, and cartridge II of FIG. 10 onto the sleeve I of FIG. 10, and cartridge III of FIG. 10 will go a distance of about 3 mm. closer to the sending line and rests against the rammer 46 of FIG. 10. Here, the sleeve I of FIG. 10 performs 2 roles: 1 - shot. 2 - very accurately and gently in perfect condition exposes the cartridge II of FIG. 10 to the axis of the bore 1 of FIG. 10, with a reverse stroke of the barrel 1 of FIG. 10 spike 53 of FIG. 10 selects free play; FIG. 10 for example 20 mm. and only then the copier 48 of FIG. 10 begins to retreat, with a further course of the barrel 1 of FIG. 10 back “dressing” on cartridge II of FIG. 10, rammer 46 rises, after which cartridge III of FIG. 10 under pressure from the magazine spring 43 of FIG. 9 begins to move to the sending line, then cartridge III will “fall” down, as an option, if there were no free play; FIG. 10 and visor 54 of FIG. 10 (it can be extended), but at this moment the visor 54 of FIG. 10 will go deep under cartridge III of FIG. 10 and support it, which is the meaning of the free wheeling; FIG. 10. Upon returning the barrel 1 of FIG. 9 in the initial position, he “dresses” on the cartridge II of FIG. 10, and the sleeve I of FIG. 9 using the lower part of the barrel 1 of FIG. 10 and reflector 46a of FIG. 10 will be thrown back and down (the reflector 46a of Fig. 10 moves the horizontal path of the sleeve back - vertically down, without unreliable small parts and springs of the classic reflector), compactly and not scattering throughout the district and without injuring its comrades with red-hot sleeves like in the classics and these comrades are faced with a choice: whether to shoot at the enemy, or to escape from red-hot shells and to shoot accurately at the enemy already becomes problematic. Because the shell flies down heavily, we make a small window at the bottom of the weapon to remove the cartridges, closed by a compact, automatic spring-loaded shutter 76 Fig14, which will be closed after each shot. Due to the complete closure of the weapon, in case of accidental explosion of a cartridge inside the weapon, the fighter will not be injured. The barrel 1 in its extreme rear position compresses the spring 55 of FIG. 14. and the buffer spring 23 of FIG. 6. on the left, the buffer spring 23 of FIG. 6 is double-sided and works both with the barrel moving forward and backward. When the weapon is cocked, the spring 55 and the spring of the buffer 23 will be preloaded by 20 ÷ 50% and can stand for a very long time, without much harm to the weapon, unlike the classics.

The supply of cartridges and the ejection of cartridges takes place without a classic shutter with its numerous and irreparable flaws, but only a small part of them: 1) sticking a cartridge. 2) unprotecting. 3) various kinds of ruptures of liners. 4) loss of the capsule from the cartridge. There are NO these and other shutter flaws in this system, and the curved grooves of the copiers - the simplest parts in free tolerances, with modern CNC walls, will not be difficult to make.

The spring unit of FIG. 6 is on the right side and is not visible in FIG. 14., there are different options for installing springs.

There are other options for the cartridge feed and cartridge ejection mechanism, as with the rammer 46 of FIG. 9 in the form of a guillotine, and without it.

In FIG. 14 the “automatic” is already cocked, for this a simple, original and spring-loaded cocking handle 68 of FIG. 14 with low effort, short stroke and convenient for quick manipulations when shooting from the right and left, both left and right hands. During a misfire or a protracted shot, you can again cock a weapon without ejecting a cartridge from the chamber (in this case, barrel 1 will be engaged with the bolt 39, during a misfire, the cartridge fires in 80% of cases when the striker is hit again and there is an opportunity to repeatedly try to fire, unlike the classic where, in the event of a misfire, it remains only to jerk the shutter and throw practically a "live" cartridge into the dirt) and without exploding the cartridge during a prolonged shot, with the risk of injuries to the face or hands, which is likely when re-cocking the classic "machine gun", but it’s possible to reload a weapon without ejecting an unused cartridge simply by poking a trunk cut into a tree, floor, wall, a stroke of just 13 mm, for example, if you take the ratio of the cocking handle 68 for example 1: 3, then the stroke of the handle will be only 13 mm. × 3 = 39 mm. To cock the weapon, we pull the lower end of the spring-loaded handle 68 forward by 39 mm., The latch that connects the barrel 1 to the handle 68 is activated, pull the handle 68 back and here the spring 79 of FIG. 14 and with an effort of about 3 times less than cocking a weapon. To distort the barrel, for example during a misfire or during a long shot, when it is necessary to remove the cartridge from the chamber, press the button 69 and the handle 68 together with the Picatinny rail 65 and rod 71 we take the barrel 1 forward with a long stroke, and then back, reloading the weapon, when In this case, an unused cartridge will be thrown out of the chamber, and instead a fresh cartridge will enter the chamber. The moving parts are under high voltage forward from the spring 55 of FIG. 14 and buffer springs 23 of FIG. 6 by pressing the shutter release 70 of FIG. 14, trigger rod 10 of FIG. 1 moves forward by turning the rotary part of the mechanism of the whisper 11 of FIG. 4, somewhere around 2.5 mm., And the sear mechanism will open FIG. 3 (the trigger is made with the holes of Fig. 14, with gear ratios for example 1: 2; 1: 3; 1: 4; 1: 5 and if there is a force on the hook for example 3 kg., Then, for example, with the ratio 1: 5 at the exit we will have 3 × 5 = 15 kg. - This is more than enough, and the hook stroke will be 2.5 × 5 = 12.5 mm. - The normal length of the trigger stroke. By the way, we have the length of the trigger rod is shorter and lighter than a pistol, which until now was an insoluble problem of a bulpap system with a long and inertial trigger draft and a draft of 10 of Fig. 3 can be either pushing or pulling. Iant, there are options with a switch of the type of fire (separate patents), although according to this scheme it may not be needed because there is not too high a rate of fire, like the classics and a cruising rate of fire, somewhere around 500 rounds per minute, weapons picks up only somewhere on the second shot of the line so that even a person who takes a weapon for the first time in his life can cut off a single shot.Trunk 1 of Fig. 1, together with the mechanism, whispered number one 3 of Figs. 2 can be rotated counterclockwise around the axis of the bore 1 of FIG. 1 somewhere at 15 ° and then the draft of descent 10 of FIG. 3 will move strictly parallel to the axis of the bore 1) and whisper 9 of FIG. 3., under the action of the combat stop 6 of FIG. 4, easily compressing the spring 8 of FIG. 3, will go down, and the moving parts will sharply go forward and after passing the segment M of FIG. 7. = 5 mm. for example, on this segment, the moving parts freely accelerate, after a collision with a sear number two 36 of FIG. 7, the trigger 37 of FIG. 7 begins to rotate counterclockwise on axis 42 of FIG. 8, the tail of the trigger 37a of FIG. 7, the hammer 40 of FIG. 7 (the drummer is short and durable, due to the larger diameter, in contrast to the thin and long striker of the classic) forward, because trigger 37 of FIG. 7, the gear ratio for example 1: 2 (there are other options), the speed of the hammer 40 of FIG. 7 will be high and the drummer passing the path L = 3 mm. briskly 40 of FIG. 8 sharply hits the cartridge capsule (not shown conditionally), a shot will be heard on the roll of the barrel, at this moment the mass of moving parts, including with the cartridge, is maximum and this favorably affects the reduction of recoil, and when impacted in the extreme forward position, only one empty barrel 1 softened by the return spring 27 of FIG. 6 and the buffer spring 23 of FIG. 6, when the barrel hits back, softening again occurs with the spring 55 of FIG. 14. and the buffer spring 23 of FIG. 6. The softening of impacts of moving parts and forward and backward was not found either in world literature or on the Internet. When the barrel 1 strikes forward, it is assumed, albeit softened by two springs, to “peck” the trunk, but if you keep your driven hand on the forearm of the weapon, then “peck” will not be because the hand will be located on the axis of the bore, and if you hold the driven hand on the handle 68 of FIG. 14, the force application vector will be located on the hinge 66 of FIG. 14, above the axis of the barrel channel, which compensates for the “pecking” of the barrel, on the same principle it is possible to make both a removable handle for the driven arm and a handle for the leading arm. The distance To FIG. 7 for example 5 mm. given to ensure that the capsule and the powder charge would work reliably, despite the scatter in the parameters of the capsule flashes and the powder charge, 5 mm. it is much more reliable than somewhere 1 mm. which is when shooting at the shutter release. If there is no shot (misfire, prolonged shot), emphasis 32 of FIG. 7 rests against the stationary delay mechanism 18 of FIG. 7 and the shutter mirror 39a will stop just on the G-Gfig line. 7, where the disengagement of the moving parts during the forward movement begins - this is the mechanism for delaying protracted shots, while the trigger toe 34 of FIG. 8 starts turning the sear number two 36 of FIG. 8 clockwise and synchronously with the full stroke of the striker 40 of FIG. 8 forward, stop 41 of FIG. 8 will fall from the sear number two 36 of FIG. 8 without engagement.

The combination of springs, the mass of the moving parts and the distance of the gas engine hole from the treasury can be chosen such that after the shot from the recoil action the speed of the moving parts forward will drop to zero and at that moment the bullet will fly through the gas outlet 12 of FIG. 5, the gas engine 13 of FIG. 5 will also trigger a short stroke piston 14 of FIG. 5 will go backward by shifting the pusher 16 of FIG. 5, for example, by 5 mm. while compressing the spring 19 of FIG. 5, wherein the delay mechanism 18 of FIG. 5 will go down and then the latch 15 will work and the pusher 16 will lock, and therefore the delay mechanism 18, while the tail of the latch 15 will rise and stand on the stroke line of the barrel stop 32 of FIG. 5, after the operation of the gas engine 13, the moving parts will go forward and the ejection of the sleeve will be at a minimum pressure in the barrel, which with the above system will give the reliability of the ejection of the sleeves very close to 100%, there will not be too high a rate of fire and there will not be any kind of breaks in the sleeves most dangerous delay in battle. Because delay mechanism 18 is omitted, barrel 1 of FIG. 5 goes forward freely after the barrel stop 32 of FIG. 5 will touch the raised tail of the latch 15, it will release the pusher 16, which, under the action of the spring 19, will return to its previous position and the delay mechanism 18, under the action of the spring 17, will also return to its previous position, with the barrel 1 returning to FIG. 5, the delay mechanism 18 freely passes the barrel stop 32 of FIG. 5. After the shot, during the course of the barrel 1 of FIG. 10 back and forth, rammer 46 of FIG. 10 and copier 48 of FIG. 10 expose cartridge II of FIG. 10 to the axis of the bore, and the sleeve I of FIG. 10 is thrown from the weapon back and down. As the barrel moves forward, the recoil momentum is divided, as in the Jackhammer automatic shotgun (Yandex - Jackhammer automatic shotgun), with a decrease in recoil. Due to the compactness of the gas engine in length (there are options for a gas engine with an absolutely short piston stroke within 5 mm.) And the design of the weapon, the gas engine needs to be placed under the barrel and the recoil arm, the silhouette of the fighter, as well as the vertical dimensions of the weapon will be reduced, unlike from a regular bullpup “machine gun”, in which the overall gas engine is almost always above the barrel, for example X95.

The barrel during the rollback can save up to 90% of the rollback speed since Phillips stop 30 of FIG. 6 compresses the return spring 27 of FIG. 6 (which, when the barrel 1 rolls back when the shaft stump comes to the BB line, the spring 27 of Fig. 6 is locked on the stop 28 of Fig. 6 and then the barrel 1 goes back by inertia), and the cross-shaped stop 29 of Fig. 6 at the end of the stroke compresses the rigid spring of the buffer 23 of FIG. 6. this increases the speed of the barrel 1 and the rate of fire, which is very important for massive moving parts (with massive moving parts, the probability of jamming of weapons from sand and dust is less), then barrel 1 of FIG. 10 “dresses” on cartridge II of FIG. 10, and the sleeve I of FIG. 10 is thrown back and down, then the barrel 1 of FIG. 13 hits the shutter 39 of FIG. 13 and on the way 4 mm. between lines BB of FIG. 13 and DG of FIG. 13 the coupling of the barrel 1 of FIG. 12 with a shutter 39 of FIG. 12. When the combat platoon 6 of FIG. 3, when the barrel moves backwards, it goes to sear number one 9 of FIG. 3 on the alpha side, dipstick 4 of FIG. 1 is at the peak of the copier 2 of FIG. 1 and whispered 9 of FIG. 3 freely goes down, without preventing the barrel 1 from going backward, then the moving parts compress in spring 55 by means of inertia the spring 55 of FIG. 14, and at the end of the stroke, the piston 22 of FIG. 6 compresses the buffer spring 23 of FIG. 6 on the left, then the moving parts momentarily stop and go forward, and if the descent is not pressed, then the combat support 9 of FIG. 4 locks on the closed sear number one 9 of FIG. 4, if the trigger is pressed, then the shooting continues until those games until the trigger is pressed or the cartridges run out. Angles alpha and beta can be different and of different configurations. There are options (these are separate patents) when the trigger is pressed during auto-fire, the whisper 9 stops at the bottom and there are no unnecessary blows to the emphasis of the barrel 6 when the barrel 1 moves back. Rearranging the thrust 10 of FIG. 14 through the holes of the trigger 70 of FIG. 14 we can regulate the force and the course of the descent over a wide range - all this is for weapons with a barrel roll, the same trigger can be done for weapons firing from an open bolt.

The stock can be made adjustable, like a VHS-2 "machine" (Yandex-weapon VHS-2), which will solve the problem of fitting weapons to different people and with different equipment.

On the upper Picatinny rail 72 of FIG. 14. You can set all kinds of sights, etc., on the lower bar 65 of FIG. 14, you can install a tactical flashlight, grenade launcher, etc.

To reduce sound with a close shot to the ear, we put the soundproof pad 73 of FIG. fourteen.

The length of the "machine" according to the bullpup system with an optimal barrel of 500 mm. it will be on the order of 580 mm., in the cocked position somewhere around 570 mm and the “machine gun” will not interfere in cars, armored vehicles, aircraft, in trenches, in trenches, or in cramped spaces, they will also be easily overcome doors, windows, hatches.

If you make a submachine gun or PDW with a barrel for example 400 mm. we get the ideal weapon with a shorter barrel stroke, due to the shorter cartridge and the bullpup system within 450 mm. arms length, you can make a retractable butt. If you take a classic 250 mm barrel., We get a full-fledged submachine gun and PDW 300 mm long. [this is shorter than the German MP-5K (Yandex is the weapon of the MP-5K), which has a barrel with a length of only 115 mm.], for hidden wearing, with a retractable butt. Moreover, we will not have a too high rate of fire - the scourge of all submachine guns with a free shutter, we will have high accuracy and accuracy of fire, from the front whisper and with minimal recoil. With this scheme, you can apply an improved pistol cartridge 7.62 × 25, making it, for example, 7.62 × 28 (a separate patent) with a pointed bullet and stuffed with the most modern effective gunpowder and you get a cartridge - a thunderstorm of bulletproof vests.

The system can be made modular by changing the barrel, several parts and placing the adapter under the cartridge 9 × 19, 5.7 × 28, etc., we get a submachine gun or PDW, without a free shutter with all its disadvantages. Through the bullpup system, gases will exit through a hole with a grid or a labyrinth 74 of FIG. 14, at the upper end of the butt plate of the butt, in the area of the nape of the fighter and will not irritate the eyes and nasopharynx. Barrel 1 can be easily replaced with a spare or other caliber and length directly on the spot, quickly and without tools since it is not rigidly fixed in the receiver, there are options (separate patents), unlike the classics, where a red-hot barrel can jam or “stick”, and when changing caliber and barrel length, an army workshop is required.

It turned out a reliable, lightweight, COMPACT, long-range weapon with high accuracy, accuracy and the lethal force of all types of fire with minimal impact.

There are options (separate patents), where there are two stores (store number 1 where store 43 is shown in Fig. 14, and store 2 is shown by dashed lines in Fig. 14. stand behind each other. To change empty store 1, instantly move store 2 backwards ( for this, as an option, you can make a movable handle 67 of Fig. 14), put it in place 1, the empty magazine 1 falls back and down and the shooting will continue almost without stopping ~ stopping long and deadly, without the ability to open instant fire like in a classic replacing an empty store. when shooting, there is always a moment for reloading weapons with magazine 2 and at the same time we can open instant fire and there will be uninterrupted fire while there are magazines in. A magazine with the optimal number of rounds, for example 22 pcs., 22 + 22 + 1 in the barrel = 45 rounds - how at the RPK light machine gun magazine. With this weapon and the magazine, the fighter has a low silhouette in a prone position and a reliable magazine due to the short size. In the submachine gun variant, you can put 3 magazines (or even 4) and then on one charge we will have 22 + 22 + 22 + 1 cartridge in the barrel = 67 cartridges.

The store needs a new design (a separate patent), it will be completely closed from sand, dirt, etc., unlike open and deadly, due to their pollution and jamming at the most inopportune moment, classic stores.

This weapon, in comparison with the known bullpups, with a barrel length of 500 mm, will be somewhere around 200 mm. shorter and will have the dimensions of a submachine gun and second-tier soldiers will be able to participate in any battles without feeling like inferior warriors with clappers in their hands, such as PDW, etc., not to mention the crazy money for their production, production of another type cartridges, logistics, etc.

In this weapon, ALL PROBLEMS of the bulpap system are REMOVED.

This “machine gun” is a universal weapon: a submachine gun, PDW, “machine gun”, a light tactical sniper rifle, and a machine gun.

The essential features of the invention:

1 - THE SMALLEST DIMENSIONS and as a result - a small mass of weapons.

2 - there will be no gaping windows for ejecting sleeves and slots for the bolt handle, as well as the hook handle itself with a reduction in the size of the weapon.

3 - we have a very compact, in view of decreasing length, gas engine, which is installed under the barrel, which will significantly reduce the recoil arm and the vertical dimensions of the weapon and reduce the silhouette of a fighter in a prone position.

4 - there are no weapons: 1) the ejector - several parts. 2) reflector - several details. 3) self-timer - a few details. 4) moderator - a few details. 5) fire type switch - a few details. 6) a long and unreliable firing pin - instead of it a short and reliable firing pin, as well as the bullpup system, we have a short, light and responsive trigger pull, shorter than pistol and it can be made either pushing or pulling, which also reduces the dimensions and weight of the weapon, this increases the operational speed of the use of weapons.

5 - weapons are simple, light, reliable, safe, technologically advanced, inexpensive and with MINIMUM DIMENSIONS.

As for CARDINAL REDUCTION, I own the patent under number 2697184 "Firearms with the barrel going forward and the most minimal return" - this is another of the countless options for this weapon.

The above weapons have GIANT POTENTIAL for subsequent upgrades, unlike modern systems, where there is ALREADY nothing to come up with.

This is a completely NEW and UNUSUAL TYPE of WEAPON under an ordinary cartridge. In the particular case - an “automatic” can be made under any cartridge, up to 7.62 × 51 NATO, these sketches are made under the Grendel cartridge.
