Description

The invention relates to a weapon that is designed so that it can be operated by foreign as well as self-propelled. For this purpose, the weapon has a modular body, which is integrated in a basic weapon housing by means of gas pressure - self-propelled - ensures the drive. This body is einbindbar in a weapon housing, for example, an infantry rifle. The same basic body can also be lafettiert, in which case a third party drive is responsible for the drive.

From the prior art, various drives such as foreign or self-propelled weapon systems are known. In third-party drives electric drives are often provided, which then drive, for example, a chain. A well-known chain drive is used in the known under the name Bushmaster or Chain Gun automatic cannon. Here necessary downtime for closing the shutter, for firing the shot, for opening the shutter and the presentation of a cartridge before the closure by a rotating, driven by a motor chain realized (http://de.wikipedia.org/wiki/M242 Bushmaster ). The closure with the preceding ammunition or cartridge is thereby fed linearly to the cartridge chamber.

In the DE 10 2006 022 622 A1 a linear supply of the ammunition is described in a gun barrel or cartridge chamber, which has a control link used for function control in the horizontal plane parallel to the path of a straight-to-leading closure of the closure weapon. For a locking of the closure, a locking link is provided, which is incorporated in the movable slide. In this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring.

A feature control for a drum weapon is not subject to public release DE 10 2008 015 892.5 , Here, a function control is also realized by means guided in scenes connecting rod. The function control itself includes the feeding of an ammunition into the drum or the respective cartridge chamber and the circuit of a drum for adjusting selbiger.

A locking centering of a self-loading handgun is the DE 199 07 967 B4 Removable and has a rotationally locked closure with warts, which is displaceable in the longitudinal direction of the weapon for driving and for inserting a cartridge in a cartridge chamber. The closure has a closure head with the help of which the closure is functionally connected by twisting with the barrel.

With the DE 196 00 459 A1 a closure for a firearm is proposed, which unlocks the locking head from the locking piece of the gun barrel end and locked during the forward movement during a backward movement of a chamber handle. The closure head has warts obliquely to the axis, whereby a rotational movement is caused during the unlocking and locking operation of the closure head from the Verrieglungsstück the barrel. The Weitern is a Drehkammerverschluss from the DE 292 22 251 U1 known.

Information about a self-loading handgun with a movable shutter with locking lugs on the bolt head can also be found in the DE 199 03 322 B4 be obtained. The closure consists of a closure carrier and the closure head, which is mounted rotatably and longitudinally movable on the closure carrier. The warts are arranged circumferentially distributed at corresponding placement points on the closure head. The barrel sits with its rear end in a sleeve, at the end of a ring of longitudinal grooves is formed, which open into an annular groove adjacent to a chamber. The locking lugs of the closure head slide when closing along the longitudinal grooves of the sleeve and run after turning the closure head in the annular groove.

The present solutions have in common that either a rotational movement of the closure head or a locking ring or the like must be involved in the process of closing and the opening of the closure.

The DE 409 091 C discloses a device for locking the closure to automatic weapons. The locking piece can be either by oblique slots, which run in parallel to the barrel parts and engage in the attached to the frame of the weapon guide pin or controlled by guide rods, which are hinged to the locking piece and the frame of the weapon and parallel to each other ,

There are efforts to be able to lafettieren self-propelled small arms. In particular, with fully automatic weapons, but there is the problem that can not be ruled out that in a remote controlled backup of the weapon in case of failure, such as cable breakage, power failure, etc., the fuse is actuated during the shooting process. A positive control of the actuator of the fuse with the actuator of the suit has the disadvantage that after releasing the trigger, the shutter requires an indefinite period of time to reach its rear catch position, may be secured at the first. The time span depends on the current position of the shutter.

With the DE 38 05 621 A1 discloses a machine gun, which additionally incorporates a self-propelled in the form of an electric linear motor as support. This self-drive is responsible for feeding the ammunition and simultaneously rotating the drum. After a broken shot, a gas piston connected to the slider is pressurized as a result of the forming gas, so that the slider is moved backwards against the weft direction, while the drum is further rotated with this movement.

The object of the invention is to show a weapon or a weapon concept that allows it to be able to lafetieren the weapon as a handgun in a simple manner.

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

The invention is based on the idea to provide a weapon which consists of a base body or a basic system, which is provided with a so-called hybrid drive, so that it can be operated as a normal handgun with self-propelled and lafettierte (lafettierbare) weapon by means of third-party.

The weapon consists of a base body, which carries next to the barrel all assemblies for a shoot including triggering an ammunition or cartridge, etc. This includes assemblies for delivering ammunition as well as locking a closure in the system. Furthermore, the base body includes a self-propelled necessary gas channel (gas channel bore) with gas piston, which can be constructed as usual in a self-propelled weapon.

This basic body with its components itself is carried by a basic weapon housing and can be introduced into a handgun housing (infantry rifle) or in a carriage (cradle) and fixed in this. As a result, the same weapon can be operated as an infantry rifle or remotely operated weapon.

In continuation of the invention, a closure system is proposed, which can be operated by both types of drives. This is also combined with a suitable firing mechanism with the appropriate security.

With regard to the use of a usable for both types of drive closure, the invention takes the technical note from the DE 409 091 C to accommodate a closure or closure carrier by a wedge-like block which can be displaced approximately vertically relative to the closure and thus to lock it, so that a form fit is produced between the weapon housing and the closure or closure carrier. As vertical, all directions are to be regarded, which are possible weapons technology, such as vertically from below, vertically laterally, vertically from above. Such a closure can be easily integrated into the body.

The preferably block-like executed locking slide has at least one nose-like extension, with which the locking slide can engage positively in a matching recess of the closure or Verschlussträger. The nose (s) should have a relatively steep flank to the barrel and can fall off slightly on the other flank. Preferably, a slightly oblique binding of the recesses (in the direction of gun barrel) has been shown in the closure or closure carrier, as this construction, a larger force absorption of the recoil is possible. Therefore, the locking slide is preferably guided obliquely forward in the weft direction sliding into the recesses in it.

The block as well as closing movement is realized and controlled by a to the weapon housing (longitudinally) movable slide. In these, in addition to the (s) guide (s) for the locking slide also for the downtime for closing the shutter, for firing shot, for opening the shutter and the presentation a cartridge in front of the shutter needed times in the form of scenes or curves involved. The responsible for the shutter movement backdrop works with at least one fixed curve, for example, integrated in the weapon housing, functionally together. Another, with the Verschiebekulissen co-operating backdrop is used for horizontal adjustment of the block. The slider should be parallel, in the preferred embodiment aligned perpendicular to the weapon housing.

The slide is in continuation of the idea preferably U-shaped, so that he can embrace the weapon housing and a stable closure system is created.

The slide can in turn be moved with its existing on both sides of the closure or Verschlusenträgers scenes of a foreign motor or self-propelled gas pressure. It is also possible to attach a slider on each side of the gun case, so that both are functional but not firmly connected. For a hybrid drive this is a little more complex. The block as well as the closure is forcibly controlled in both variants by the curves embedded on both sides.

The block can be integrated laterally on the weapon base housing. Preference is given to a bilateral lateral integration. Alternatively conceivable, however, is also a central position of the block.

Shown is a modular weapon system that allows use of the modular base body or weapon base as a self-powered handgun and as lafettierbare foreign-powered weapon. The weapon or the weapon system consists of the modules basic body - weapon housing - handgun - cradle Lafettenträger together. The basic body module includes all weapon-technical assemblies including assemblies for a self-propelled drive. In the Weapon Case - Handgun module, the manual trigger for firing is preferably an integral part of this module. Accessories such as sighting, laser rangefinder, etc. can be attached to the weapon housing in a known manner. In the cradle module, the assemblies for external drive as well as the shot firing are part of this module. These are preferably the motor as well as a chain drive for the closure system.

In Fig. 1 is a rootstock 100 for a handfire 200 ( Fig. 3 ) as well as lafetable weapon 300 ( Fig. 6 ). The main body 100 ( Fig. 1a 6 includes a locking slide which is movable approximately vertically in the direction of the running axis and which has at least one lug 7 in at least one corresponding recess 8 of the closure 4 and the closure carrier 5, respectively Lock the closure engages the barrel 3. As advantageous two to three lugs 7 are proposed on the locking slide 6. The preferably block-like locking slide 6 is preferably aligned laterally relative to the base weapon housing 10.

In Fig. 1a the shutter feeder 1 is shown. Opposite the basic weapon housing 10 is a parallel aligned slide 11 with scenes 12, 13 movably mounted. The gate 12 as Zuführkulisse cause the supply of the shutter 4 and the slide 13 as a slide curve moving the locking slide 6. For this purpose, the locking slide 6 is guided by a bolt or connecting rod 15 in the gate 13. With the Zuführkulisse 12 of the slider 11 functionally working together a fixed gate 14, as further Zuführkulisse. The curve 14 may be incorporated in the basic weapon housing 10. The common functionality is made possible by a further connecting rod 16, which is connected at one end to the bolt carrier 5 and engages with the other end in both scenes 12, 14.

The different backdrops of the scenes 12, 13, 14 arise from their task. Thus, it can be clearly seen that the slide curve 13 has a long straight slide section 13.1. This section 13.1 defines the time of the open locking slide 6. However, the shorter link section 13.2 of the slider curve 13 includes the locking time, i.e., the time in which the shutter 4 remains locked until the shot is fired. Involved here is an internal return option, so that the barrel 3 and the shutter 4 are floating. The straight gate section 12.1 of the Zuführungskulisse 12 determines the rear idle time of the shutter 4 for feeding the ammunition (Munitionszuführzeit). During this time, the slide 11 can continue driving due to an overstroke, the deposited connecting rod 16 remains in the angled rear end 14.2 of the curve 14th

The shutter 1 should be provided on both sides of the gun barrel 10, for example in the form of two slides 11. The slider or the slider 11 (not shown in detail) (via a bolt V) and / or a self-propelled (via a gas piston linkage G, here only indicated) connected such that this (e) is (are) moved by the respective drive. It is preferred, as already mentioned, a U-shaped embracing of the common slider 11 to the base arm housing 10, which allows a simple (central) connection of the drives to the slider 11.

The essential movements and interactions of the scenes or feeds 12, 13, 14 are in the Fig. 2a to d The illustration for the purpose of illustrating the processes is only of an exemplary nature and refers in a perspective manner to one side of the system.

In Fig. 2a The lugs 7 of the locking slide 6 fully engage in the recesses 8 of the closure 4. The connecting rod 16 is located in the rising end 14.1 of the gate 14 and in the longitudinal section 12.2 of the gate 12th

With moving the slider 11 to the rear to open the shutter 4, the connecting rod 15 of the locking slide 6 slides along the link 13 down in the gate section 13.1, while the connecting rod 16 remains in the short slide guide 12.2 and 14.2 in the end of the gate 14, so that the Shutter 4 is not moved ( Fig. 2b ). With the entrance of the connecting rod 15 in the lower gate section 13.1 and thus completed unlocking the shutter 4 (lugs 7 are pulled out of the recesses 8 and release the shutter 4), the connecting rod 16 slides in the gate transition between the gate sections 12.1, 12.2 and is slid behind the slide 11 and the fixed slotted guide 14 along this positive control (the slide 14) together with the closure 4 or lock carrier 5 behind ( Fig. 2c . Figure 2d ). For the ammunition supply, not shown, the connecting rod 16 slides in the lower link section 12.1, so that although the slider 11 along the connecting rod 15, 16 but not the shutter 4 can be adjusted. This is stored together with the connecting rod 16. However, the slider 11 can in turn continue in the time of ammunition supply (presenting the ammunition 21 in front of the shutter 4). The connecting rods 15, 16 are as long, until with the forward movement of the slider 11, the corresponding curve sections to the connecting rods 15, 16 attack and move them forward in the direction of gun barrel 3.

This embodiment of the arbitrator 11 as well as the scenes 12 etc. allows that the basic system or the body 100 for both types of drives provides the necessary downtime (will be explained). It does not matter whether the slide 11 is driven by the gas piston G or by the external drive 305 (303, 304) is moved.

Fig. 3 shows a representation of an integrated in this construction in an advantageous manner Zündauslösung with fuse.

A primer of 20 marked a placed in the barrel 3 and transported by the shutter 4 cartridge 21 is pierced by an integrated in the shutter 4 firing pin 22 and ignited it.

The firing pin or Zündnadelauslösung for single fire, single sustained fire or continuous fire is here excited by a kinematics 30. Connected thereto is a lever 103 which, as will be described, is supported by a manual trigger 202 or a magnet 305 (FIG. Fig. 7 ) can be adjusted.

The kinematics 30 is composed of a rocker-like about a pivot point D mounted first lever 31, a mounted around another pivot point R second lever 32 in conjunction with a hammer 33 together. This is by a spring force, not shown around its pivot point S movable and functionally connected to a firing pin 34 in the lock carrier 5 in a manner not shown. The first lever 31 of the kinematics 30 is functionally coupled to the locking slide 6.

The function is generalized as follows:

If the closure 4 is securely placed and locked by the locking slide 6, the lugs 7 engage in the recesses 8 of the closure 4. In this case, the lever 31 connected to the locking slide 6 acts to pull the second lever 32 away from the striking piece 33 and this can be moved about its axis S to move the firing pin assembly 34 together with firing pin 22 against the primer 20 of the cartridge 21.

However, if there is no proper locking, the locking slide 6 remains in its initial position, the lever 31 is then tilted such that the second lever 32 of the hammer 33 assumes that it can not be moved.

The locking slide 6 is, for example, in an unwanted intermediate position, which also no proper locking is guaranteed, the hammer 33 remains subordinated by the lever 32.

In general, such active systems must be protected. It is therefore proposed to integrate into the kinematics 30 one, but preferably two, fuses 35, 40 which monitor a shot firing which permits a corresponding shot with proper locking and prevents it with the shutter 4 not locked.

For this purpose, the firing pin 34 is formed by a first fuse 35, a lever 37 with recess 38, secured, wherein the recess 38 corresponds to the cross section of the firing pin 34, so that in the locked state, the lever 37 the firing pin 22 with firing pin 34 at a distance 36 to the primer 20 stops. Striker 22 and firing pin 34 are preferably made in one piece and also form a technical / constructive unit.

In order to avoid, for example, that an unintentional ignition of the cartridge 21 could take place in an unsafe state, a further (second) fuse 40 is incorporated. This further fuse 40 is realized by a placement of the firing pin 34 as a parallel fuse 40 to the first fuse 35 by a further lever 41. This lever 41 cooperates with the kinematics 30, to which a movable means 42 is integrated, which connects the lever 41 with the kinematics 30 functionally.

Upon successful locking of the shutter 4, the movable means 42 is located on the lever arm of the first (lower) lever 31 of the kinematics 30. This guarantees a subsidence of the (upper) sub-position 41 via the path 43. Since the safety lever 37 has released the firing pin system 34, the firing pin system 34 is moved spring-supported with firing pin 22 via the path 36 for piercing the primer 20.

In the event of faulty locking, the movable means 42 can not release the full path 43 for the lower position 41, which requires the lower setting 41, in order to ensure that the firing pin system 34 abuts the firing pin 22, so that even if the firing pin system releases unintentionally Ignition by the second fuse 40 is excluded.

It is understood that the two paths 36 and 43 are coordinated.

Only for the sake of completeness it should be mentioned that with a further fixed, preferably Waffengehäuseseitig incorporated backdrop 50 a check is provided with which it can be checked whether the gun barrel 3 is properly locked. If this is not the case, the entire shutter supply 1 / locking system is locked.

The above-described base body 100 can now in turn in a handgun housing 210 ( Fig. 4 ), for example, an infantry gun 200, here with a target device 201 and supports 205, are involved ( Fig. 5 ). In the weapon housing 210, a manual trigger 202 is preferably permanently installed, ie this should or may be part of the handgun housing 210. For the installation of the main body 100 or the basic weapon housing 10, the handgun housing 210 has two suspension points 203, 204 which cooperate with suspension points 101, 102 of the ground weapon housing 10. The main body 100 can then be firmly fixed by bolts 206, 207 in the weapon housing 210. Shown is a single fire, fast single fire as well as continuous fire shooting handgun 200.

Based on Fig. 6 the operation of the manually triggerable weapon 200 will be explained in more detail.

For shooting, the manual trigger 202 is actuated. With actuation of the manual trigger 202 presses this lever 103 up. For optimal and easy operation, the manual trigger 103 has a double nose assembly 208 ( Fig. 4 ), wherein the lever 103 rests in the rest position on both noses. The dual nose assembly 208 causes first a slight attack on the manual trigger 202 occurs, but then an increase in pressure is necessary to lift the lever 103. This has the advantage that the shot firing takes place optimally. When the lever 103 is high, the blockage for the kinematics 30 is canceled, the shot takes place. About the described gas piston G is then again in a known manner, the shutter 4 or the shutter carrier 5 moves backwards, placed a new cartridge 21 in front, the kinematics 30 blocks, as already described.

Fig. 7 FIG. 3 shows the body or cradle 310 of a launcher gun 300. Components of this cradle 310 are the components responsible for the foreign drive, such as a motor 301 and two chains (drive chain, fastener chain) 302, 303 and a turnover wheel 304 for the shutter drive. Connectable to the closure chain 303 here is the bolt V of the slide 11 (FIG. Fig. 8 ). The magnet 305 in turn provides for lifting the levers 103 to trigger the shot, for which the magnet 305 has a so-called magnetic nose which raises the lever 103.

The operation is as follows:

The closure 4 or closure carrier 5 is moved in a known manner by the drive 301 and via the chains 302, 303. The necessary downtime of the shutter 4, as already stated, realized by the Zuführkulisse 12 in the slide 11. During this time, then also the automatic shot triggering, for which the magnet 305 is actuated and the magnetic nose raised, the kinematics 30 is released. It is understood that with the magnet 305, a component that actuates this functionally cooperates, but for the sake of clarity, it is not further illustrated.

The integration into the cradle via the suspension points 101, 102 of the base armature housing 10 and suspension points 306, 307 in the cradle 310. The integration of the cradle 310 to a Lafettenträger not shown in detail then takes place via further bearing points 308, 309th

Fig. 8 shows the integrated into the cradle 310 main body 100 to create a fully automatic, foreign-powered weapon 300. The gas outlet into the gas channel bore 109 is preferably closed for this variant.

The closing or opening of the gas channel bore 109 can be done by a stepped bolt (not shown in detail), so that the bore 109 of the base body 100 can be selectively opened or closed.
