Description

[0001] The invention relates, in particular, to a method for unlocking a breechblock of a weapon system, for example, an externally powered machine gun. The invention particularly concerns a forward-travel release of a breechblock during the forward travel of the recoiling masses following their recoil.

[0002] Self-propelled or externally powered weapon systems are well known, particularly autocannons. In such weapon systems, a cartridge is presented to a breechblock, and a breechblock drive moves the cartridge into a gun barrel or cartridge chamber within the gun barrel. The breechblock movement includes idle times during which the breechblock may not be moved. The locking between the breechblock and the gun barrel is achieved using well-known locking systems, such as block breechblocks, wedge breechblocks, rotary lug breechblocks, etc.

[0003] A rotary lug bolt and a weapon with a rotary lug bolt are known from DE 10 2010 009 427 B4. The rotary lug bolt has a bolt carrier and a bolt head mounted therein with multiple locking lugs. The rotary lug bolt is designed such that the unlocking, during which the cartridge case is released from a cartridge chamber in the weapon barrel, is not controlled exclusively by the relative movement between the bolt head and the bolt carrier. For this purpose, a control cam section is formed in the locking piece, which interacts with a correspondingly designed control section in the bolt head. During unlocking, the rotary movement of the bolt head is converted into a screwing movement relative to the locking piece. This screwing movement leads the bolt head screwing out of the locking head. The same control cams and control cam sections also take over the locking of the bolt.

[0004] DE 10 2009 058 551 B4 discloses another rotary lock. A tongue-and-groove interlocking mechanism secures a rotary lock cylinder to the bolt carrier in the unlocked position. A guide shell of the bolt carrier can thus be reduced to the extent that it only secures the rotary lock cylinder against tipping out of its functional axis.

[0005] A locking system for an externally and / or internally driven weapon with a block lock can be found in DE 10 2009 011 939 84. When the returning mass of the weapon recoils, the block lock is controlled to unlock via control cams on the bolt carrier and is re-controlled to lock when the weapon recoils.

[0006] As a rule, the bolt or bolt head is locked to the weapon barrel in such a way that the locking itself is carried out by a chamber sleeve, which in practice is connected to the weapon barrel and, if necessary, to a recoil damper, etc.

[0007] EP 2 018 509 B1 discloses a functional control system, particularly for the linear feeding of ammunition into a weapon barrel. The externally powered weapon or externally powered weapon system comprises a locking ring with lugs, which is preferably located on the weapon barrel and overlaps the latter, as well as lugs on a bolt head. When the bolt head rests against the weapon barrel, the protruding locking ring is rotated, whereby the lugs of the locking ring are moved behind the lugs of the bolt head and the bolt is locked. The locking ring is rotated by a bolt guided in a control cam. Unlocking occurs by reversing the movement of the bolt in the control cam. The downtimes required for the weapon are achieved here by the interacting control link and the drive link.

[0008] DE 37 12 905 A1 discloses a machine gun with a firing control. The bolt consists of a bolt upper section and a slide, each of which is arranged separately within the weapon housing for longitudinal movement and can be positively coupled to each other via connecting means. In the event of a cartridge malfunction, the decoupled bolt upper section remains in the locked position, while all other weapon functions or movements continue to operate, not decelerated. A gas-pressure-controlled decoupling of the bolt upper section from the slide is provided.

[0009] Further weapon systems with a breech are described in DE 409 091 C and DE 139 766 C.

[0010] Such systems, especially externally driven systems, especially chain drives, have the problem that when the bolt is unlocked and the empty cartridge case is extracted, large forces act on the chain, and the extraction forces must be applied by the chain.

[0011] The invention therefore aims to solve this problem.

[0012] This problem is solved by the features of patent claim 1 and claim 14, respectively. Advantageous embodiments can be found in the subclaims. The invention is based on the idea of ​​minimizing the forces acting on the bolt drive when unlocking the bolt and extracting the cartridge case. Thus, the forces acting on the bolt drive when using an external drive, e.g., a chain, when unlocking the bolt and extracting the cartridge case are to be reduced or even eliminated.

[0013] According to the invention, these tasks of the bolt drive are transferred to the bolt and the weapon barrel; the bolt and weapon barrel take over the unlocking of the bolt and the extraction of a cartridge case, independently of the bolt drive.

[0014] In implementation of the idea, the recoil of the weapon after the shot is used to unlock the bolt from the gun barrel and eject the cartridge case. In other words, the recoil and thus the returning masses of a weapon are used to unlock and eject the cartridge case. As is well known, when a shot is fired, recoil occurs, whereby the returning masses of a weapon, such as the gun barrel and bolt, are accelerated in the opposite direction of the fire. During the recoil, part of the recoil energy is stored in recoil springs of a recoil device or similar. This energy is used to move the returning masses forward again if they are in the forward motion.

[0015] During the weapon's recoil, a mechanical separation and a mechanical connection of the bolt drive and the bolt are provided. For unlocking the bolt and ejecting the cartridge case, the bolt is now mechanically separated from the bolt drive during the recoiling masses. At the end of the recoiling masses' advance, the mechanical separation created during the recoil is removed, and functionality is restored. The bolt drive and the bolt are mechanically coupled again.

[0016] This basic idea creates a new approach to circumventing the deficiencies and problems of an external drive. It also takes into account the fact that the bolt of an externally powered weapon is stationary at the moment the shot is fired, i.e., locked, while the external drive continues to run (see, for example, DE 10 2015 121 771 A1, DE 10 2008 060 217 A1).

[0017] Continuing this idea, the actual unlocking of the bolt and the extraction of the cartridge case are performed during the forward movement of the recoiling mass following the recoil. The unlocking of the bolt and the extraction of the cartridge case take place during the forward movement of the recoiling mass.

[0018] The bolt according to the invention preferably comprises a bolt carrier and a bolt head carried by the carrier. The bolt carrier can be held and transported by a bolt slide. In this preferred configuration, the bolt drive is mechanically connected to the bolt carrier via the bolt slide for the weapon function.

[0019] As the recoiling masses return, the mechanical separation between the bolt slide and the bolt carrier occurs. At this point, the bolt carrier can move relative to the bolt slide. After reversal and during the subsequent forward movement, the mechanical connection between the bolt carrier and the bolt slide is reestablished.

[0020] During recoil, the bolt head moves back along with the weapon barrel as part of the recoiling mass. During this recoil, the bolt carrier and bolt drive separate. The bolt head is freely movable relative to the bolt carrier during recoil.

[0021] As the recoiling masses advance, the bolt head is rotated in such a way that the connection between the bolt head and the barrel is released, unlocking the bolt. Furthermore, the bolt head is caught by the bolt carrier. This unlocking allows the barrel and chamber to move further forward without the bolt head, allowing the now stationary bolt head, with its extraction claw, to extract the cartridge case from the barrel, at least partially.

[0022] These functions and processes are implemented by a specially designed device. This device utilizes existing components of the locking system in a special way. The device works in conjunction with a specially adapted bolt carrier.

[0023] The device has at least one first movable slide on the bolt carrier pointing towards the weapon barrel. In the simplest version, this can be inserted in the bolt carrier. When the weapon barrel, together with the bolt head, reaches this slide, it moves within the bolt carrier. In the process, at least a second slide is activated. This further slide is rigidly connected to the bolt slide and locks the bolt carrier and the bolt slide against each other. By actuating the at least one second slide, this locking or mechanical connection between the bolt carrier and the bolt slide is released. With this separation, the mechanical connection between the bolt carrier and the bolt drive, namely the external drive, is interrupted. At the same time, the bolt carrier can now move freely, to a limited extent.

[0024] As the recoiling masses advance, at least one of these slides is re-energized, and the mechanical connection between the bolt carrier and the bolt slide is restored. The bolt carrier is once again rigidly connected to the bolt system.

[0025] In a further development of the invention, at least a third slide ensures that, when the bolt carrier is reconnected to the bolt slide, the bolt carrier does not assume its initial position (i.e., all the way forward) at this time. Further movement of the bolt carrier is blocked. This at least one third slide is overrun during the recoil of the returning masses and is therefore ineffective during the recoil itself.

[0026] As the bolt head and barrel continue to advance, the bolt head is rotated along or within a guide or groove in the bolt carrier. This rotation unlocks the bolt head from the chamber. The barrel moves further forward without the bolt head held in the bolt carrier, so that the barrel moves away from the (unlocked) bolt head. As the barrel moves away from the bolt head, the extraction process of the cartridge case begins. The bolt head pulls the cartridge case from the barrel. The cartridge case is released and already partially extracted when the barrel is in the zero position.

[0027] The bolt or bolt head with bolt carrier, which is firmly connected to the bolt drive via the bolt slide, can then be moved to its rear position as part of the weapon's actual function. The extracted cartridge case is ejected in the usual way, and a new cartridge is presented to the bolt.

[0028] The bolt carrier then assumes its initial position toward the firing position when the bolt returns in the actual weapon function via the bolt drive. At least one third slide is controlled by a first cam in such a way that a lock is released. The bolt carrier itself can then be retracted or pushed back into its initial position by springs.

[0029] The advantage of this idea is that the bolt drive, namely the external drive, no longer has to exert the force required to pull the cartridge case from the barrel. This allows for a smaller drive, such as a smaller motor, to be used. The weapon can also be made smaller.

[0030] If the recoil fails due to a misfire, the device no longer interferes with the actual function of the weapon.

[0031] In a further development of the invention, a firing pin in the bolt head is only cocked when the bolt is locked. Once the bolt is locked, a firing pin spring, which is tensioned during the locking process, is released, firing the firing pin. The firing pin spring can be released mechanically or electrically, e.g., magnetically. Because the firing pin spring is only released when the bolt or bolt head is locked, an unintentional firing of the firing pin during transport of the bolt is prevented, thus preventing the weapon from being fired. Such an approach can be found, for example, in DE 10 2015 121 770 A1.

[0032] Thus, a weapon system with a breechblock is proposed, wherein the breechblock is mechanically connected to a breechblock drive of the weapon system for the weapon function. A device is designed such that a mechanical separation between the breechblock and the breechblock drive occurs during the weapon's recoil, i.e., the recoiling of the returning masses of the weapon system. When the returning masses advance, a mechanical connection between the breechblock drive and the breechblock is re-established via the device.

[0033] The bolt is formed by at least one bolt carrier and a bolt head, with the bolt carrier being designed to support the bolt head. To minimize or even eliminate the forces acting on the bolt drive when unlocking the bolt and ejecting a cartridge case, the bolt head is freely movable relative to the bolt carrier.

[0034] To separate the bolt from the weapon system's bolt drive during the return of the weapon system's recoiling masses, a device is designed such that a mechanical separation between the bolt and the bolt drive occurs during the return of the weapon system's recoiling masses. When the recoiling masses advance, the device restores the mechanical connection between the bolt drive and the bolt.

[0035] For connecting or disconnecting the bolt from a bolt slide, which functionally interacts with the bolt carrier, the device has at least one connecting rod. The connecting rod is firmly attached to the bolt slide at a rear end (as seen in the firing direction). The front end can be connected to and separated from the bolt carrier.

[0036] The present concept can also be used in testing. In particular, it can be used to determine cartridge behavior, especially the extraction force behavior. The present design can be assigned the function of a testing device. Each shot can be measured, meaning the data is known after each shot. For this purpose, measurement points, e.g., using strain gauges, can be provided on at least one connecting rod. Such a testing device is therefore also considered a weapon system.

[0037] The invention will be explained in more detail using an embodiment with drawing.

[0038] It shows: Fig. 1 a representation of a weapon barrel with a device according to the invention in a side view, Fig. 2 a representation of Fig. 1 in a plan view, Fig. 3 the carrier or the carrier system from Fig. 1 in a view from below, Fig. 4a in Fig. 1 shown device in a side view, Fig. 5 the device from Fig. 4 in a view without lid from above, Fig. 6 the device from Fig. 4 in a sectional view Fig. 7a sectional view of the bolt carrier according to Fig. 1 , Fig. 8 a representation of a further section of the bolt carrier from Fig. 7 , Fig. 9a view of the bolt carrier from Fig. 5 with firing pin, Fig. 10 another view from Fig. 9 .

[0039] In Fig. 11 denotes a barrel assembly of a weapon (not shown in detail). This barrel assembly 1 comprises at least one weapon barrel 2 and a bolt head 3. The weapon barrel 2 and bolt head 3 are guided over a carrier 4 or fastened to it. The bolt head 3 is carried by a bolt carrier 5. The bolt head 3 and the bolt carrier 5 form a bolt. In the presently preferred embodiment, the bolt carrier 5 is functionally connected to a bolt slide 6, and this is connected to a drive (not shown in detail), in this case an external drive.

[0040] A motor is provided as the external drive, which moves a chain or connecting rod (not shown in detail) to move the bolt carrier 5 and thus the bolt from a forward position (firing position) to a rearward position (loading position). The external drive realizes the necessary downtimes of the bolt within the weapon.

[0041] A device is identified by 20. The purpose of the device 20 is to mechanically separate the bolt carrier 5 and the bolt slide 6 when the bolt head 3 is still locked and is moved counter to the firing direction with the recoiling weapon barrel 2 as part of the recoiling masses of the weapon system or weapon. When the recoiling masses advance, the device 20 removes this mechanical separation.

[0042] Fig. 2 shows the pipe assembly 1 from Fig. 1 in a top view, Fig. 3 from below onto the support system 4.

[0043] The Fig. 4The device 20 can be seen in an enlarged view. The device 20 can be seen in interaction with the bolt carrier 5 and the functioning of the bolt head 3. A guide groove or guide curve 21 for a control bolt 22 of the bolt head 3 is incorporated into the bolt carrier 5, preferably laterally.

[0044] The bolt carrier 5 is connected via at least one connecting rod 23 ( Fig. 6 ) is detachably connected to the bolt slide 6. The connecting rod 23 is firmly attached to the bolt slide 6 with a rear end, as seen in the firing direction. The front end is connected to the bolt carrier 5 and can be separated from it.

[0045] The connecting rod 23 ensures that the bolt carrier 5 is firmly connected to the bolt slide 6 for transporting the bolt in the actual weapon function. In addition to the connecting rod 23, a compression spring 24, preferably a helical compression spring, is integrated or arranged between the connecting slide 6 and the bolt carrier 5.

[0046] The device 20 further comprises at least one first slider 25. This first slider 25 protrudes from the bolt carrier 5, pointing in the direction of the weapon barrel 2 ( Fig. 4 ). As long as the first slide 25 is not actuated, ie is not pressed, the bolt carrier 5 and the bolt slide 6 form a mechanical unit via the connecting rod 23.

[0047] In addition to the first slider 25, the device 20 comprises at least a second slider 26. This serves to mechanically separate the connecting rod 23 from the bolt carrier 5 and is controlled by the first slider 25 for this purpose, so that the connecting rod 23 can release the connection with the bolt carrier 5 at the front end ( Fig. 4 ).

[0048] The Fig. 4the guide cam 21 incorporated in the bolt carrier 5, which is intended to guide the control bolt 22 of the bolt head 3 for unlocking the bolt head 3 from the weapon barrel 2. The bolt carrier 5 also carries at least one spring sleeve 45 and a tensioning sleeve 46 mounted thereon so as to be displaceable and rotatable. Compression springs 41, 42, preferably helical compression springs, and a tensioning pin 43 for a firing pin 40 located in a bore 44 in the bolt head 3 are incorporated into this. The compression spring 41 is used to cock the firing pin 40. The function of the compression spring 42 is to move the bolt head 3 into an open position and to hold it in its unlocked position.

[0049] In Fig. 6 These are shown in a sectional view. 31 denotes a compression spring of the first slide 25, and 32 denotes its stop piece for the first slide 25 in the bolt carrier 5.

[0050] The mode of operation is as follows: According to the figures, the bolt or bolt head 3 is locked and the weapon is fired. Ignition has occurred. The weapon barrel 2 with chamber sleeve, the bolt head 3 as well as the assemblies 40 - 46 integrated in / on the bolt head 3, as returning masses of the weapon, move backwards against the direction of fire. In doing so, the weapon barrel 2 strikes the first slide 25 and moves it along its path 25' within the bolt carrier 5. In doing so, due to the shape or contour of the first slide 25, this first slide 25 pushes away at least one second slide 26. A gap created by this second slide 26 and in Fig. 8The illustrated position 50 is removed, and the front end of the connecting rod 23 is exposed within a bore 11 of the bolt carrier 5. The mechanical connection between the bolt carrier 5 and the bolt slide 6 is removed. The bolt carrier 5 is carried along by the returning masses, while the connecting rod 23 can slide freely forward within the bore 11. In doing so, the connecting rod 23 moves over at least a third slide 29, pushing it away as the returning masses return.

[0051] During the recoil, the returning masses are moved forward again together with the bolt carrier 5 in the direction of fire, and the forward movement is initiated. It is understood that this recoil or the associated path of the returning masses is taken into account in the length of the bore 11.

[0052] As the bolt carrier 5 advances, the connecting rod 23 remains suspended on a front edge 52 of at least one third slide 29. The mechanical connection to the bolt slide 6 is thereby restored.

[0053] Due to the mechanical coupling of the bolt carrier 5 with the bolt slide 6, only the bolt head 3 with the locked weapon barrel 2 now moves forward. The control bolt 22 on the bolt head 3 is guided along the guide cam 21, and the bolt head 3 is rotated. The rotation of the bolt head 3 unlocks the bolt head 3 from the weapon barrel 2, which then detaches from the bolt head 3 as it continues to advance and moves away from the bolt head 3. A cartridge case (not shown) held by an extraction claw 54 of the bolt head 3 is at least partially extracted from the weapon barrel 2 during this advance of the weapon barrel 2. At the time the weapon barrel 2 is in the zero position, the cartridge case is released from the weapon barrel 2.

[0054] The bolt carrier 5 assumes its starting position during its return transport by the bolt slide 6, i.e. during the actual bolt transport when the weapon is in operation. In this case, the at least one third slide 29 is controlled by a cam 71 on the carrier 4, and the position is released by the front edge 52 of the slide 29. The front end of the connecting rod 23 slides under the at least one second slide 26 and moves back to its starting position. The front end of the connecting rod 23 comes to rest behind a rear edge 53 of the at least one second slide 26, which, driven by a compression spring 27, is placed in front of the front end of the connecting rod 23. The front end of the connecting rod 23 is secured to the rear by an edge 55 in the bolt carrier 5 ( Fig. 8 ).

[0055] The compression spring 24 supports the bolt carrier 5 in assuming its initial position. The bolt slide 6 can move the bolt carrier 5 further into its rear position within the weapon. This ejects the cartridge case (not shown in detail).

[0056] Preferably, two connecting rods 23 are used. These are aligned parallel to each other, with the bolt head 3 arranged between them. This construction increases the functional reliability of the device 20. When using two connecting rods 23, two compression springs 24 and two second slides 26 are also provided within the device 20 on the bolt carrier 5. They interact functionally with the respective connecting rod 23. The slides 26 are supported in their function by compression springs 27, preferably helical compression springs. This structural design then preferably also requires two third slides 29 ( Fig. 5) and two cams 71 on the carrier 4.

[0057] The firing pin 40 is cocked when the bolt head 3 is locked to the weapon barrel 2. For this purpose, the bolt carrier 5 together with the bolt head 3 is moved forward again in the direction of the weapon barrel 2 by the bolt slide 6 and this is moved forward again by a bolt drive (not shown in detail).

[0058] A fourth slider 47 is pushed upwards in the initial position by a spring 48 ( Fig. 9 ). When the bolt 3 or bolt carrier 5 advances in the actual weapon function, the bolt head 3 slides with its control bolt 22 along the guide cam 21 and locks with the weapon barrel 2. During this rotary movement, the clamping bush 46 is guided along its clamping cam 49 with the firing pin 40 against the fourth slide 47 to the rear, opposite to the direction of fire, the compression spring 41 located therein is tensioned and thus the firing pin 40 ( Fig. 10 ).

[0059] When the bolt head 3 has completed its rotational movement, the fourth slide 47 runs onto a cam 70 in the carrier 4. This causes the fourth slide 47 to move downward, and the clamping bushing 46 loses its support. The clamping bushing 46 and firing pin 40 are pushed forward by the released compression spring 41. The firing pin 40 emerges from the bore 44 of the bolt head 3 at the front and ignites a cartridge (not shown in detail). In this position, a fifth slide 60 locks the fourth slide 47 in its lower position via a bolt 61.

[0060] Slide 60 remains in this position until the unloading process. When the bolt slide 6 retracts, cam 70 actuates this fifth slide 60, so that the fourth slide 47 can be pushed back into its original position by spring 48. The cycle begins again with the onset of the weapon's recoil.

[0061] The weapon or weapon system can fire both targeted single shots and continuous fire. Reference symbol
