Description

The invention relates to a modular and compact weapon, in particular one that is powered by an external device or by itself, that can be mounted on a mount. The weapon is designed in such a way that the weapon can be assembled and disassembled without tools. The weapon does not have any screw connections, etc. The individual components of the weapon are supplemented with individual parts and mechanically linked or connected to one another. The modular character of the individual components is retained despite the additional individual parts (assemblies belonging to the functions of the main assemblies). The individual parts are attached to the modules or the modules to one another primarily using rail and guide systems. These are integrated on the one hand to the individual parts and on the other hand in/on the modules and are coordinated with one another (complementary). Other fastening devices on or within the weapon or the components are bolts, pins, locks, hold-down devices and the like. A module is understood to be a self-contained functional unit or assembly.

The DE 20 2011 103 707 U1 describes a modular weapon carrier system. It discloses a four-legged hydraulically vertically movable weapon platform with at least three joints per leg. A modular weapon platform or a modular weapon carrier is the DE 20 2009 007 415 U1 removable. With the EN 10 2006 004 954 A1 A modular self-protection throwing device is published. The EN 20 2012 004 430 U1 also shows a modular launcher. A modular launcher in the DE 20 2010 008 821 U1 is characterized by the fact that the modular magazines of the launcher are attached to a base plate by screwing etc. and the modular electronics unit is pivoted to the end of the magazines for contact with the base unit.

The US2590153A also reveals a modular weapon.

The US 7,820,271 B2 shows a handgun that can be assembled from individual modules. The assembly is done using hooks and lugs and corresponding guides in the counter modules.

From the WO 2010/102727 A1 A hybrid weapon is known that can be integrated into a gun carriage. In the handheld version, the weapon is self-propelled, in the built-in version it is powered by an external drive. The weapon consists of a weapon base body that accommodates a weapon barrel, a block lock and a locking slide. A firing pin release and the components of the self-propelled device are also integrated into the base body. The weapon's locking system is connected to the self-propelled device or to the external drive via a bolt. The self-propelled device is then closed.

The EN 10 2008 060 214 A1 discloses a bolt drive for a weapon with linear bolt feed. The bolt drive is formed by a crank drive which converts a rotary movement into a linear forward and backward movement.

The DE 10 2009 011 939 A1 deals with a locking device for a simple locking system, in particular for an externally or self-propelled weapon. Here, the closure or closure carrier is supported and locked by a wedge-like block that can be moved approximately vertically to the closure, so that a positive connection is created. All directions that are technically possible with weapons are considered vertical here, such as vertical from below, vertical from the side, or vertical from above. Furthermore, an ignition trigger with fuse is proposed, which has kinematics which is composed of a first lever mounted like a rocker around a pivot point and a second lever mounted around a further pivot point in interaction with a striking piece. Two safeguards are integrated into this kinematics, which only enable a shot to be fired if the block lock is properly locked. This second security is achieved by placing a firing pin system as a parallel security to the first security using another lever. This lever interacts with the kinematics, for which a movable means is integrated that functionally connects the lever with the kinematics. When the lock is locked, the movable means rests on the lever arm of the first (lower) lever of the kinematics. This guarantees that the (upper) assumption will disappear over a path. Since the safety lever has also released the firing pin system, the firing pin system with firing pin is moved with spring support over the path to be taken by the firing pin to pierce the primer cap. This triggering of the ignition forms the striking mechanism for the firing pin.

From the unpublished one DE 10 2014 108 469.1 is a bolt with a bolt carrier and a bolt head as well as a separate striking mechanism for triggering of the firing pin integrated in the breech head. The striking mechanism has at least one, preferably two levers, for placing a spring-loaded striking piece. A rear tensioning ramp and a front ramp on the bolt carrier serve to tension the spring of the hammer in the striking mechanism and to press the at least one lever out of position with the hammer to release the hammer. A firing pin safety is also integrated into the firing pin in the bolt head. This design eliminates the need for a firing pin spring that would otherwise be necessary. However, the firing pin can only be knocked off if the bolt head is locked in the weapon by turning it.

The present invention aims to demonstrate a concept for a weapon system in order to be able to design a weapon in a simple and compact manner. The weapon should preferably be able to be assembled and disassembled without tools, in particular for maintenance and repair work.

The problem is solved by the features of patent claim 1. Advantageous embodiments are set out in the subclaims.

The invention is based on the idea of building the weapon in a completely modular manner, whereby the individual parts are assembled into modules and these hold or support each other. For this purpose, the weapon is divided into assemblies that serve as carrier units for the individual parts and/or the modular assemblies of the weapon. A first assembly can be a modular weapon housing. The weapon housing is the carrier unit for a locking system of the weapon with its individual parts, which is installed in the carrier unit. The weapon housing module can also be supplemented with the weapon barrel(s). Another modular assembly is a weapon cradle. The weapon housing module with locking system can be inserted into this modular carrier unit and held by/in it. It must be possible for the weapon housing to slide in the weapon cradle (mounting) for the weapon housing to return. Another modular assembly, a weapon drive, is also connected to the weapon cradle. This includes an electric External drive and the mechanical bolt drive, which in turn is connected to the bolt system on the weapon housing. The bolt drive moves the bolt and includes the idle times of the bolt during which it is put down.

The mechanical connections of the individual parts on the modular assemblies or the modular assemblies with one another are primarily carried out via rail systems on the individual parts and corresponding guides, grooves, etc. on or in the assemblies. Furthermore, mechanical connections are created using hold-down devices, recesses, etc., bolts, pins and the like.

An assembly consisting of individual parts is, for example, a weapon's striking mechanism. This is assembled into a modular assembly. Other individual parts of the weapon include a breech with breech head (also called chamber), a firing pin, a breech block and a slide for controlling the breech and the breech block. These aforementioned individual parts are inserted into the weapon housing together with the striking mechanism or pushed onto the weapon housing. The individual parts then form a supplemented modular assembly together with the weapon housing.

The idea of also doing without a spring to tension the firing pin itself was taken up. The force to move the firing pin is applied by a hammer of a striking mechanism. To move the firing pin a predetermined distance in the bolt head, the hammer is only tensioned when the slide advances, preferably after the bolt or bolt head is placed in the locking position. In this case, only the spring of the hammer is tensioned. When the bolt is locked, the hammer is moved towards the firing pin due to the spring tension when it is released and strikes it. The firing pin then fires the shot. When the bolt is opened and transported to its rear (unlocked) position, the spring for the hammer is relaxed again.

In the basic position (also called transport position), when the shutter is in its rear position, this spring, also known as the hammer spring, is always relaxed. The spring is also durable. These properties ensure a high level of functional safety and reliability. By tensioning the spring of the hammer during the forward movement of the bolt head and releasing it, the shot is released regardless of the forward speed of the bolt and therefore independent of the cadence. This is made possible by the fact that Cocking takes place when the shutter advances and triggering is only possible when the shutter is fully locked.

Since the firing pin does not have its own firing pin spring, which brings the firing pin within the bolt head from a firing position to a rest position, the firing pin is transferred from its firing position to its rest position via a driver in conjunction with the striking mechanism. This drive becomes active when the shutter is not yet fully unlocked, but is already moved to the rear position. For this transfer, the driver in turn engages a front stop surface in the end region of the firing pin. Before the bolt is completely unlocked, at least one driver should have brought the firing pin into its rest position.

The path of the firing pin to pierce a primer of an ammunition within the bolt head is limited by a rear stop surface in the end area of the firing pin. In a preferred design, this stop surface is integrated into the firing pin (firing pin projection) itself. However, alternatives are possible. The follower is designed in such a way that it is only removed from the firing pin projection by this distance to release the firing pin.

When the bolt head is returned, the firing pin is moved back to the rest position by the driver and then held in this position. The function of the drive is supported by a safety device that protects the firing pin against its own movement. For this purpose, in a preferred embodiment, a recess is made in the end region of the firing pin, into which a bridge or a connecting rod is inserted. Alternatives are known.

The driver can also act as a safety device for the firing pin. The driver is permanently in contact with the firing pin and only releases the firing pin shortly before the hammer is supposed to hit the firing pin. This release occurs when the shutter is locked.

To ensure that the spring-free firing pin is safely driven and guided, the drive has pins on the side that slide into two opposing grooves on the sides of the weapon housing when the bolt or bolt head is guided into its two end positions (front, back). The drive is forced through these grooves. These grooves ensure that the drive comes into contact with the front stop surface of the firing pin.

The weapon housing, which has been supplemented with the percussion mechanism, can then be inserted into the weapon cradle, for example from above. The weapon casing is held down in the weapon cradle by a rear hold-down device that can be swiveled and a front holder on the weapon cradle. The hold-down devices ensure that the weapon housing is not permanently installed in the weapon cradle. This allows the weapon housing to be moved back/forward in the weapon cradle (mounting).

Furthermore, a modular recoil damper is integrated into the weapon. This preferably consists of two recoil dampers, which in turn are simply inserted into recesses in the weapon cradle and the weapon housing and are easily integrated into the weapon. The recoil dampers are firmly integrated into the weapon cradle, but have some play in the weapon housing. The recoil dampers are secured by a bracket that can be attached to the weapon cradle and is also used to hold down the front part of the weapon housing.

In a further development of the invention, the weapon in its special design has a weapon barrel bundle module. This weapon barrel bundle comprises at least one, preferably several weapon barrels, which are stored and held in the common weapon barrel bundle in preferably two bearings of the weapon barrel bundle. Because the weapon barrel bundle can consist of just one or just two weapon barrels, customer requests can be met more flexibly and/or weight can be saved. To accommodate the weapon barrel bundle, the weapon housing has a weapon barrel bundle holder, which preferably consists of two fixed lunettes, which in turn have a foldable, removable or pivoting upper part. Rollers are integrated in the upper part and the lower part of the lunettes, which support the rotation of the weapon barrel bundle. The integration of a roller in the upper part of the lunette has proven to be sufficient.

The weapon drive module can also be flanged to the weapon cradle module via a simple quick connection and plugged into it, for example using locking pins or the like. Any play in the fastening of the two to one another must be excluded so that the functional connection between a connecting rod and the slide of the closure is ensured. The connecting rod of the drive and the slide of the closure can be easily connected to one another, for example by inserting the connecting rod into a groove underneath the slide. Since these two modules have to be separated less frequently for maintenance and/or servicing, a screw connection can also be provided here.

The constructive separation of the weapon drive from the weapon cradle has shown the advantage that the modular weapon drive can be individually designed depending on customer requirements, including the electrical drive, etc. The modular structure of the individual assemblies of the weapon as well as the use of standardized individual parts themselves also means that the individual modules are consistently reproducible in their production and can therefore be easily interchanged with each other.

The special thing about the weapon or rather this weapon system is that the individual parts and the modular assemblies can be attached to one another without tools. Tools are also not required for disassembly.

The proposed design is designed here for a weapon in the 7.62 mm caliber range, for example, but can also be transferred to other calibers.

What is proposed is a weapon, in particular an externally powered weapon, with at least one weapon barrel, a weapon housing, a locking system with a striking mechanism integrated in the weapon housing, a weapon cradle and a weapon drive, in this case a motorized one (in the case of self-powered weapons, another design known to the person skilled in the art, e.g. gas piston, see also EP 2 440 881 B1 ) complementary, whereby the locking system comprises a lock, a locking block, a firing pin and a slide with control cams. For tool-free assembly and disassembly, the weapon housing, the weapon cradle and the weapon drive are designed as modular assemblies that serve as carrier units. The locking system is accommodated by the weapon housing. The weapon housing has a holder in the weapon housing for the locking block and the striking mechanism. The lock and the slide have lateral rails and guides via which they can be mechanically connected to complementary rails and guides in the weapon housing by inserting and sliding. The weapon housing can be inserted into the weapon cradle. The weapon housing is held down in the weapon cradle with little play by means of a hold-down device integrated into the rear part of the weapon cradle and in the front area by means of a holder in the weapon cradle. The at least one weapon barrel is carried by the weapon housing. The weapon drive carries at least the lock drive, preferably this as well in the case of an external drive (motor). An internal drive can be connected to the weapon drive. The weapon drive can be detachably connected to the weapon cradle. The bolt drive of the weapon drive is functionally connected to the slide on or in the weapon housing.

In Fig. 1 an externally powered weapon 100 is shown in an exploded view. This weapon 100 is formed from individual modular assemblies which, as a whole, ensure the function of the weapon 100 and can be assembled in a simple manner and mechanically connected to one another using simple fastening means. The basis of the modular assemblies are so-called carrier units (main assemblies), through which the stability of the weapon 100 is created. They are used to hold individual parts or assemblies among each other. The modular main assemblies, assemblies and individual parts are preferably designed in such a way that tools etc. are not required during assembly or disassembly.

The weapon 100 consists of the main assemblies weapon drive 1, weapon cradle 2 and weapon housing 3. In the preferred embodiment, the weapon 100 includes not only one weapon barrel, but three (5, 5 ', 5"), which together form a weapon barrel bundle module 10.

The weapon housing module 3 is used to accommodate the individual parts of the locking system with a lock 15 with a locking chamber or locking head 15.1, the striking mechanism 16 as well as a firing pin 17, a locking block 20 and a slide 21 (control block) ( Fig. 3 ). The percussion mechanism 16, which forms the trigger device of the weapon 100, is integrated into a trigger housing 100.1 and this is integrated into the weapon housing 3. The trigger housing 100.1 is a modular part of the weapon 100 and forms a self-contained and functional unit.

A case ejector 18, which engages in a groove 19 in the bolt head 15.1, is inserted laterally into a groove in the weapon housing 3 and anchored therein. This causes a reproducible ejection of a cartridge case (not shown in detail) after the ammunition has been fired when the bolt 15 is guided to the rear.

The weapon barrel bundle 10 has a control body 11 in a partial area 10.1, which has a control curve 12 on the circumference, with which the weapon barrel bundle 10 can be rotated about a common barrel bundle axis. The weapon barrels 5, 5', 5" are in turn mounted in a front bearing 10.1 and a rear bushing 10.2 in the weapon barrel bundle 10 and are integrated into it like a drum. The weapon barrels 5, 5', 5" are preferably caulked in the rear bushing 10.2. A drive 13 is provided for the rotation, preferably an electric drive that is designed as a module. Since this is not subject to continuous use, the drive 13 can be powered by batteries etc. (not shown in detail). Alternatively, the drive 13 can be supplied with power via a power cable.

In the front area ( Fig. 2 ), the weapon housing 3 has a tube holder or tube holder 22, into which the weapon tube bundle 10, with for example three weapon tubes 5, 5 ', 5", is inserted and held by it. The tube holder 22 is formed by two fixed bezels 22.1, which one foldable, removable or swiveling top 22.2 have so that the weapon barrel bundle 10 can be inserted into the bezels 22.1. The upper part 22.2 is designed here as a quick-release fastener. The weapon barrel bundle 10 can also only include one or two weapon barrels 5, 5 '. The storage in the weapon barrel bundle 10 can remain the same.

The weapon cradle 2 module ( Fig. 4 ) is also based on a carrier unit and is used to hold the weapon housing 3 as well as all components or assemblies of the weapon 100. The components to be accommodated are the drive 13, a return damper 4, the weapon housing 3 supplemented by the locking system and the striking mechanism 16 Case ejector 18 and the weapon barrel bundle 10.

A T-slot 14 integrated on both sides of the weapon cradle 2 can be used to accommodate additional connecting parts such as ejection plate 14.1, ammunition feed, etc., which can be inserted into the T-slot 14.

Due to the internal return in the cradle, the weapon 100 does not need to be mounted. The weapon cradle 2 itself forms the carriage for the weapon 100, via which the weapon 100 can be mounted on a vehicle etc. To mount the weapon 100, the weapon cradle 2 has two bearing points 2.1, 2.2.

The weapon drive module 1 ( Fig. 1a ) here is an electric drive, not shown in detail, as an external drive 1.1 of the weapon 100. Also integrated into this module on the bottom side is a locking drive connected to the drive 1.1, here a connecting rod 36 ( Fig. 1a ), which is guided via a crank 35 along a drive curve 37.

The connecting rod 36 is guided in the drive curve 37, which defines the downtimes of the weapon 100 or the shutter 15 (see also DE 10 2008 060 217 A1 ). A front cam 36.2 of the connecting rod 36 engages in the drive cam 37 and a rear cam 36.1 behind a fixed nose 41 of the slide 21, for example. The length compensation between the connecting rod 36 and the drive cam 37 takes place through the crank 35. Behind the fixed nose 41 there is, for example, a movable slide 42 through which the connecting rod 36 moves the breech 15 back into the rear position when a shot has been fired, but prevents the breech 15 from being transported if no shot has been fired. The play or the distance between the nose 41 and the movable slide 42 corresponds to the path of the weapon return, so that it cannot exert any force on the weapon drive ( Fig. 3 ). As already stated, the locking system of the weapon 100 is controlled via the slide 21 (see also DE 10 2009 011 939 A1 ).

In a special embodiment, an emergency stop device 40 integrated in the weapon cradle 2 interacts with the movable slide 42, which is actuated by the weapon return. If the weapon returns fails, the emergency stop remains engaged by the emergency stop device 40

As a further safety measure, particularly during transport of the weapon or an object carrying the weapon, such as vehicles of all kinds, the weapon barrel bundle 10 can be transferred to a transport position, whereby the control cam 12 only makes half a turn and thus the weapon barrel 5 (5', 5") is brought out of alignment with the bolt 15.

Based on Fig. 2 to 9 The actual assembly, ie the assembly of the weapon 100, will now be explained in more detail.

In a first assembly step, the striking mechanism unit 16 with the breech block 20, the breech 15 or breech head 15.1 and the slide 21 are attached to or in the weapon housing 3 ( Fig. 2 ). The slide 21 is preferably U-shaped and surrounds the weapon housing 3 from below. The striking mechanism 16 and the locking block 20 are placed in a trigger housing 100.1 and inserted into the weapon housing 3 from below. The receptacle in the weapon housing 3 for the trigger housing 100.1 with striking mechanisms 16 and breech block 20 are structurally coordinated with one another in such a way that a positive installation is achieved. The firing pin 17 is installed in the breech 15 or breech head 15.1 before the breech 15 is inserted into the weapon housing 3.

The closure 15 and the slide 21 are attached to the weapon housing 3 via rails/guides/groove 15.2 on the closure 15 and rails/guides/groove 21.1 on the slide 21 as well as coordinated rails/guides 3.1 (also groove) on the weapon housing 3. The The closure 15 and the slide 21 are pushed onto the carrier or the weapon housing 3. The pin 30 preferably engages through the hole in the closure block 20 into a further control cam located behind it and aligned parallel to the front control cam 21.2 (not shown in more detail).

The modular recoil damper 4 can now be inserted into the weapon 100 ( Fig.4 ). The recoil damping 4 used here comprises two recoil dampers 4.1, consisting of a housing 4.1.1 for accommodating a spring (not shown in detail) and bolts 4.1.3, one front and one rear, attached to both sides of the front sides 4.1.2 of the housing 4.1.1. These recoil dampers 4.1 are mounted in recesses 2.3 of the weapon cradle 2 and in cooperating recesses 3.3 of the weapon housing 3. The recoil dampers 4.1 are firmly integrated in the weapon cradle 2, but later have some play in the weapon housing 3.

The modular weapon housing 3 equipped with the aforementioned components can then be inserted into the weapon cradle module 2 ( Fig.5 ). The insertion takes place from above. A hold-down device 31 which is firmly attached to the rear end 2.2 of the weapon cradle 2 can be folded down about an axis. After the weapon housing 3 has been inserted, the hold-down device 31 can be folded forwards, whereby the weapon housing 3 is held down in the rear area.

This hold-down device 31 is in the Fig. 6a , 6b shown in more detail. It has a bolt 31.1 which is flattened on one side between its clampings so that the bolt 31.1 has a semi-circular shape in this area. For inserting the weapon housing 3, this bolt 31.1 stands vertically in the weapon cradle 2. To hold down the rear end of the weapon housing 3 in the weapon cradle 2, the hold-down device 31 is, as already mentioned, folded forwards/upwards so that the surface of the semi-circular area of the bolt 31.1 comes to lie over the end of the weapon housing 3 and the weapon housing 3 is held in the rear area of the weapon cradle 2 with little play, but sliding of the weapon barrel housing 3 in the weapon cradle 2 is ensured.

The front holding down of the weapon housing 3 in the weapon cradle 2 is carried out by a holder 33, which is U-shaped in the vertical plane and rests with its legs on the weapon housing 3 in the front area with little play ( Fig.5 ). This bracket 33 also serves to securely hold the recoil damper 4 in the weapon cradle 2 and in the weapon housing 3. The bracket 33 engages bolts 2.5 of the weapon cradle 2 via its front recesses or forks 33.1 on the legs. These have a corresponding guide 2.5.1. In the rear area of the legs, the bracket 33 has recesses 33.2 on both sides, which are placed on guides 3.5 of the weapon housing 3. The rear bearing points 33.3 (Fig. 5.1) of the bracket 33 are locked to the weapon cradle 2 by corresponding bolts 2.6 (on both sides). These bolts 2.6, which are designed as locking bolts, are shown in Fig. 5.2. These also have a semicircular shape with a flattened surface. When the bearing points 33.3 rest on the flattened surface of the locking bolts 2.6, the locking bolts 2.6 are rotated forward, whereby the semicircular shape engages in the semicircular (complementary) recesses of the bearing points 33.3 and prevents the bracket 33 from moving back.

The tube change drive 13 is inserted into the weapon cradle 2 in an installation space specified for this holder ( Fig. 7 ). The tube change drive 13 is preferably pushed into a T-slot in the weapon cradle 2. The T-slot should be integrated into the lower part of the weapon cradle 2. After the tube change drive 13 has been integrated, a drive cam 13.1 points upwards, so that it easily engages in the control cam 12 of the control body 11 of the modular weapon tube bundle 10 to be installed with the integration of the weapon tube bundle 10. The barrel changing drive 13 is mechanically secured by a pin 34 in the weapon cradle 2, which is inserted behind the barrel changing drive 13, penetrating the weapon cradle 2 on both sides.

In a next step, the feeder 8 can be mounted in or on the weapon 100 ( Fig.8 ). The feeder 8 is attached with its upwardly folding feeder upper part 8.1 via another pin 38, here at the rear end of the bracket 33. The feeder 8 is located in the area of the ejection guide of the weapon cradle 2.

The weapon tube bundle 10 is integrated by inserting it into the tube holders 22 provided for this purpose (steadies 22.1) of the weapon housing 3 ( Fig. 9 ). Attached to these pipe holders 22 are quick-release fasteners 22.2, which enable changing attachment to the pipe holders 22. During installation, the drive cam 13.1 of the drive 13 engages in the control cam 12. With the installation of the weapon barrel bundle 10, a weapon barrel 5, 5 ', 5" of the weapon barrel bundle 10 is aligned with the closure 15.

It goes without saying that the weapon barrel bundle 10 can also consist of just one weapon barrel 5 or two weapon barrels 5, 5'. The weapon barrel bundle 10 module easily accommodates these variants.

When the weapon drive module 1 is mechanically connected to the weapon cradle module 2 via quick connectors (not shown in detail) and previously the connecting rod 36 is connected to the carriage or slide 21, the weapon 100 is completely assembled and functional as soon as the weapon drive 1.1 (here a motor) is supplied with power.

Fig.10 and 11 show a slightly transparent representation of the breechblock 15 of the weapon 100. The breechblock 15 or its breechblock head 15.1 is in the embodiment described here by the breechblock block 20 ( Fig.3 ) is locked. It should be noted at this point that the design of a block lock is not restrictive. The slide 21, also called control slide, with its integrated control cams 21.2, 21.3, serves, as already explained, for the transport of the lock 15 or the lock head 15.1 and the control of the breech block 20. The control cams 21.2, 21.3 are preferably integrated on both sides in the slide 21. The pin 30 guided through the front control cam 21.2 of the control slide 6 functionally connects the breech block 20 and the striking mechanism 16 with the control slide 21. The breech block 20 is controlled by this pin 30. In the stored front position of the breech 15, when the weapon drive continues to run but the breech 15 itself is not moved any further, the breech 15 is locked by moving the breech block 20 up along the control cam 21.2 and the striking mechanism 16 is triggered. After the shot has been fired and the weapon recoils, the breech 15 is unlocked again.

In the second control cam 21.3, the further, here U-shaped connecting rod 61 is guided, which engages from above in a recess 15.3 of the closure 15 or the closure head 15.1. When the shutter 15 has been locked in its front, stored position by the shutter block 20, which is controlled high by means of the front control cam 21.2, the firing pin 17 is released by the second control cam 21.3. For this purpose, the connecting rod 61 is guided out of the recess 15.3 along the rear, second control cam 21.3. In this position, the weapon housing 3 has a correspondingly upwardly directed pocket 3.2, which enables the connecting rod 61 to be controlled.

The control slide 21 is moved by the shutter drive, as already described. The breech drive is designed in such a way that the breech 15 is placed in its front and rear positions, with the breech 15 being locked in the front position and an ammunition (not shown in detail) being presented to the breech 15 in the rear position. The control slide 21 continues to run in the stored positions. Particularly in the front stored position of the closure 15, the locking is then initiated and carried out by the continuing control slide 21.

The firing pin 17 for firing the ammunition (not shown in detail) is integrated in the bolt head 15.1. This firing pin 17 has a tip 17.1 at the front and a base 17.2 in the end area 17.3. A stop surface of the firing pin 17 in the end area 17.3 is marked with 17.4. In the preferred version, the striking mechanism 16 is integrated in the weapon housing 3 below the bolt 15.

The percussion mechanism 16 includes a trigger rocker 50, which is functionally connected to the locking block 20 via the pin 30. The trigger rocker 50 in turn acts on a fuse 51 for a trigger 52 and this works with a hammer 53. The impact hammer 53 uses a telescopic push rod to operate it 53.1 on. The other end of the push rod 53.1 is supported on a clamping slide 54, which is in mechanical connection with the control slide 21. A spring 53.2 is attached to the telescopic push rod 53.1.

The trigger rocker 50 engages the safety 51 with a nose 50.1 and can press it downwards. The trigger rocker 50 has a claw 50.2 on the upper edge. This claw 50.2 serves to accommodate a driver 55 that engages a front stop surface 17.4 and comes into contact with the claw 50.2 when the bolt 15 is fed and put down. The driver 55 is in turn designed so that it rests against a front stop surface 17.4 of the firing pin 17 and can be pivoted about a pivot point. The stop surface 17.4 of the firing pin 17 is preferably incorporated in a protruding manner as a firing pin projection 17.4. A rear stop surface 17.5 (rear firing pin projection) in the end region 17.3 of the firing pin 17 defines a path S that the firing pin 17 moves in order to be struck into its ignition position (firing position).

For a safe movement and guidance of the spring-free firing pin 17, two carriers 55 are preferably integrated. These also each have a pin 55.1 on the side. These pins 55.1 slide together with the firing pin 17 and the bolt 15 when the bolt 15 is transported into its rear and front positions in a corresponding guide 3.1 or groove ( Fig.10 ).

Fig. 12 and 13 show the interaction of the individual striking mechanism parts in the stored rear position of the bolt 15 or the bolt head 15.1.

The hammer 53 lies with the spring 53.2 at rest and relaxed below the bolt head 15.1 in the hammer mechanism 16. The bolt block 20 is in its rest position and is deactivated. The trigger rocker 50 is pulled down and does not exert any pressure on the safety 51. The safety 51 blocks the trigger 52, which with its catch edge 52.1 places the catch edge 53.3 of the hammer 53 underneath.

When the slide 21 and thus the closure 15 move forward, the cocking slide 54, which also triggers the hammer 53 and thus the shot, is also moved. The push rod 53.1 of the hammer 53 is guided along an elongated hole 100.2, which is located in the trigger housing 100.1 of the weapon 100. In the stored front position of the shutter 15, when the shutter drive and the control slide 21 continue to run, but the shutter 15 itself is not moved any further, this is the case Spring 53.2 partially tensioned. The spring 53.2 is then tensioned as the control slide 21 and thus the tension slide 54 continue to run. The closure 15 is locked by driving the closure block 20 up along the control cam 21.2.

When the locking block 20 is raised, the trigger rocker 50 is pressed against a spring 51.1 of the fuse 51. The trigger rocker 50 simultaneously pulls the driver 55, which has entered the recess 50.3 as the closure head 15.1 advances, downwards. For this purpose, the weapon housing 3 has a downward-pointing pocket 3.4 on both sides for the pins 55.1 of the driver 55 to move downwards. This downward path included in the pocket 3.4 should correspond to the path S of the firing pin 17, which it requires for its function to trigger the ignition. The driver 55 thus releases the firing pin 17.

At the same time, the trigger rocker 50 presses on the safety 51 and thus on the spring 51.1. When the safety 51 is pressed down, it clears the way for the trigger 52. The hammer 53 remains positioned on the catch edge 52.1 of the trigger 52. This holding is supported by a trigger spring 52.3.

In the second control cam 21.3 of the control slide 21, the further, here U-shaped connecting rod 61 or a bridge is guided, which extends from above via its recess 61.3 into a recess 15.4 of the closure head 15.1 and into a recess 17.6 ( Fig. 3 ) of the firing pin 17 intervenes. When the shutter 15 has been locked in its front, stored position by the shutter block 20, which is controlled high by means of the front control cam 21.2, the firing pin 17 is released by the second control cam 21.3. To do this, the connecting rod 61 is guided along the rear control cam 21.3 out of the recess 15.4 of the closure ( Fig. 10 ). This connecting rod 61, which serves as further security, releases the firing pin 17. For this release by the connecting rod 61, the weapon housing 3 has an upward-pointing chamber or pocket 3.2 on both sides into which the connecting rod 61 can escape from its guidance in the weapon housing 3. So that the connecting rod 61 holds the firing pin 17 firmly and securely during the transport of the breech 15 or the breech head 15.1, this connecting rod 61 is also positively guided on both sides in side guides/grooves in the weapon housing 3 (not shown in more detail). The U-shaped connecting rod 61 in turn engages via a pin 61.2 of the connecting rod 61 in the curve 21.3 of the control slide 21 and with a pin 61.1 located opposite in a corresponding groove / guide 3.1 of the weapon housing 3.

All safeguards for the firing pin 17 have now been released.

The actual mechanical triggering of the impact hammer 53 is carried out by the cocking slide 54 ( Fig. 11 , 12 ). This has an approach ramp (incline) 54.1. The ramp 54.1 passes under the trigger 52, along which a roller 54.2 is guided. By changing the position of the rollers 54.2, the trigger 52 is pivoted about a pivot point D, whereby the catching edge 52.1 of the trigger 52 is removed from the catching edge 53. 3 of the impact hammer 53. The ramp 54.1 determines the triggering time, ie the ignition time. The later the ramp 54.1 hits the trigger 53, the later the shot is fired. The spring-loaded hammer 53 now strikes the free firing pin 17, causing the firing pin 17 to move. This path S of the firing pin 17 is limited by the rear stop surface 17.5 of the firing pin 17.

The trigger rocker 50 in conjunction with the follower 55 can also serve to limit the travel of the firing pin 17. The follower 55 engages the front impact surface 17.4 of the firing pin 17 when the latter has traveled the distance S.

When the shot is fired and the control slide 21 moves the bolt 15 or the bolt head 15.1 back to its rear position, the bolt block 20 is released. The trigger rocker 50 is moved upwards. The (hammer) spring 53.2 is completely released again via the cocking slide 54 and the hammer 53 is pushed back and put down (held) by the bolt 15 or the bolt head 15.1 itself. When the cocking slide 54 slides back, the roller 52.2 of the trigger 52 is moved to its original position via its release spring 52.3. In the process, the trigger 52 is rotated back about the pivot point D. The safety 51 for the trigger 52 is then inserted via the spring 52.3. This process takes place in a very short time.

As long as the bolt 15 acts on the relaxed hammer 53 placed to the rear in the weapon housing 3 or in the trigger housing 100.1, the catch edge 52.1 of the trigger 52 and the catch edge 53.3 of the hammer 53 are not in direct engagement. When the bolt 15 advances and the hammer 53 emerges from the weapon housing 3 (trigger housing 100.1), its catch edge 53.3 strikes the ready catch edge 52.1 of the trigger 52.

For a jam-free function or operation of the weapon 100, a positive guide for all moving components of the weapon 100 is provided (increasing safety and functional reliability). The weapon housing 3 therefore has a groove or guide on both sides for guiding the pins 55.1 of the driver 55.

Fig. 14 shows in a slightly transparent representation the disengaged connecting rod 61 for releasing the firing pin 17 seen in the direction of fire.

For a safe interruption of the weapon 100 with a transition to a secured state, particularly in the event of a power failure, a magnet 71 is provided, which interacts with a safety device 70. The safety device 70 is formed by a bolt 70.2 guided longitudinally on a rod 70.1. This is guided forwards and backwards with the closure 15 or closure head 15.1. In the event of a power failure, this magnet 71 falls off and its spring presses onto the rod 70.1. The rod 70.1 moves the bolt 70.2, which lies transversely to the firing pin 17, into the closure 15, for example by tilting the rod 70.1, so that the bolt 70.2 comes into engagement with a hole 17.7 in the firing pin 17. The firing pin 17 can thus be secured in any position of the breech 15 within the weapon. This meets the requirement of an EOC fuse (Electrical Operated Controlle). This EOC requirement specifies that a safety must be present at the last function of the weapon. This security can be used in a weapon 100 as described above, with at least one weapon barrel 5, 5 ', 5", a weapon housing 3, a percussion mechanism 16 integrated in the weapon housing 3, a weapon cradle 2, and a weapon drive 1, with the slide 21 to Transport of a closure 15 or closure head 15.1, which is moved by a closure drive 35, 36, 37.

As already stated, the impact mechanism described above is not limited to use for block closures 20. The insert can also be intended for other types of closures that are generally known, including bolt closures ( DE 10 2005 045 824 B3 ). The percussion mechanism is also independent of the type of drive ( DE 10 2009 011 939 A1 ; externally or self-powered) of the weapon 100 itself can be used.
