Abstract

A multiple-barrel weapon (1) is proposed, having a belt system (5) which can not only hold a conventional or other round (6) and may itself be a component of the round (6), but, together therewith, forms a cartridge chamber (22) for the multiple-barrel or multiple-tube weapon (1) as a result of which it is possible to dispense physically with a dedicated complete cartridge chamber. Stars (12, 13) of a roller breech are responsible for transporting the belt element system (5), wherein shells (12.1, 13.1) of the stars (12, 13) partially chamber the belt element (4) in the firing position.

Description

DESCRIPTION

More barreled weapon

The invention deals with a multi-tube weapon preferably in the small caliber area but also in the medium caliber area. The multi-tube weapon is characterized by the fact that it does not itself have its own chamber, since this function is taken over by the belt member of a Gurtzuführsystems.

Multi-barrel or barrel weapons have the advantage that the tubes or barrels are not stressed as much as simple weapons, even at high firing cadences or frequencies. The most well-known multi-barrel weapon is the Gatling. Gatling weapons are automatic firearms whose reload mechanism is operated by means of the rotation of the barrel arranged around an axis of rotation.

DE 1 728 588 A describes a multi-barrel drum gun with rotary tube runs. This gun relies on the principle of an open-chamber closure system. Here, the ammunition is brought from an insertion position into an ignition position and then into a tube ejection position. The same principle is reflected in DE 1 728 611 C, which, however, deals more closely with a revolver firearm. A multi-purpose weapon further known US 3,041, 939 A and US 4,836,082 A.

From DE 1 728 018 C ammunition for a launcher with laterally open chamber is known. The ammunition is characterized by its shape. The weapon briefly described here also has an open-chamber locking mechanism with a drum bearing. The drum in turn is rotatably mounted and has a chamber, which is placed in a Mun- nitionseinlegung so that the ammunition can be inserted laterally. This is then placed in an ignition and then in a Auswerferstellung. DE 1 728 019 B also deals with the same subject. DE 1 728 022 A relates to a sealed closure with an open chamber and caseless ammunition. DE 1 728 088 A claims an open-chamber closure mechanism which inter alia houses the chamber closes in an ignition position. A rapid-fire contactor is further disclosed by DE 1 728 131 A.

US 1 856 022 A relates to a machine gun and handgun with two gun barrels. The loading of the ammunition takes place through a slot in the closure or weapon housing. The individual projectiles together with propellant charge are connected to each other via connecting tracks and are pushed through a kind of ratchet through the slot in the weapon. At the same time the band is separated by a knife assembly. The bullet comes to rest in a cartridge chamber of the weapon in front of the shutter. Thereafter, the projectile and the closure are transferred to a so-called closed position and ignited the propellant charge by means of a compressed gas.

From US 3,696,705 A is known a combustible webbing girded ammunition for feeding caseless ammunition into an automatic weapon which burns in the chamber of the automatic weapon. This eliminates the problem that the straps fall down after removing the ammunition from the weapon. The webbing runs across each caseless cartridge. Gears push the cartridge forward, separating the strap from the subsequent cartridge.

DE 44 23 750 A1 discloses an automatic monotube firearm for endlessly deliverable cartridge ammunition. Two counter-rotating drums are used, each with six symmetrically arranged, movably mounted half-chambers. These form between the two drums directly opposite the barrel a cartridge chamber completely closed on the circumference. Simultaneously with the opposite rotation of the drums of the cartridge belt is moved through the respective chamber with. Between the drums while a temporarily closed, the combustion gas pressure resistant cartridge chamber is formed. Spring elements provide the half chambers for the purpose of optimal transportability of the cartridge belt in the most favorable pivoting direction prior to engagement in the cartridge belt. A firing of the firing pin via a toothing of a control disc and whenever it is ensured that the chamber is completely closed. The rotation of the half chambers via gears of a pneumatic gear motor, which is driven by the returned muzzle gases. This results in a somewhat shorter construction and a much higher rate of fire (cadence). Based on this idea, the invention has the object to show a multi-tube weapon, which is also small-scale.

The problem is solved by the features of claim 1. Advantageous embodiments are given in the dependent claims.

In order to arrive at a light and fast firing multi-tube weapon is provided that the weapon itself no longer has its own (complete) chamber, in which the ammunition must be inserted, not two half-shells of two mutually rotating drums form the chamber, but the function the cartridge chamber is taken over by the belt system itself, which supplies the ammunition to the weapon. The belt system thus forms one or the replacement cartridge storage. Accordingly, the belt member itself is designed so that it can perform the tasks of a cartridge chamber. The belt system is flexible, so that it can be aligned with the barrels or tubes.

The belt system can accommodate a conventional ammunition but also be part of the ammunition. The sleeve bottom of the ammunition can close (or seal) the belt member in the former case. Here, the cartridge support the formation cartridge chamber, the cartridge material are taken into account in the design of the belt member. Alternatively, there is the possibility that the belt member has a closed bottom. In this case, then the propellant charge and the projectile could be introduced into the belt member in the assembly. Each belt member can thus take all the ammunition (cartridge = sleeve + cartridge bottom) or parts thereof (propellant charge + projectile). In the latter case, the igniter structure for the ammunition is then to be integrated in the belt member floor. The sleeve as well as Gurtgliedboden simultaneously acts as a seal of the cartridge chamber towards the rear of the closure. It is understood that the projectile is located within the belt member and does not form a trailing edge. The cartridge receptacle or the belt member itself may be metallic and / or non-metallic type, for example of steel and / or plastic.

This belt system is guided between the barrels and a shutter of the weapon to supply the ammunition located in the belt members one of the runs. To accommodate the belt members two oppositely rotatable stars are involved, which in turn have a number of (half) shells circumferentially corresponding to the number of runs. Both encompass the respectively supplied belt member. As preferred, the incorporation of a so-called roll closure - similar to an open-chamber closure system - has shown with two stars, which in opposite directions rotationally receive the belt member in the firing position. The roller shutter with its stars thereby supports the formation of the replacement cartridge bearing so that it teilverkammert the cartridge bearing belt members and thus supports the formed by the belt members cartridge chamber in the strength / function, the cartridge bearing itself by the closure part of the roller shutter itself seals.

The fact that the belt member (with cartridge as well as without) takes over the function of a cartridge chamber (take over), but only supports this, has a constructive advantage in the design and practical implementation of the stars. Thus, the shells in the stars as well as the stars themselves do not have to be 100% equal and match, small Tollerranzen are thus functionally acceptable.

Parts of the roller closure can be an integral part of the barrel itself. Alternatively, there is also the possibility that the second star can be decoupled from the barrel bundle. Here then a separable connection between the barrel and the star should be provided in the axis of rotation over which the star and the shutter can be rotated with.

Both stars also serve to transport the belt system. At least the second star forms an open chamber for receiving the belt member, wherein in the firing position both stars are such that they surround the belt member, which has taken the firing position with the ammunition. The second star and the shutter are in turn moved by the rotation of the barrel bundle with this. The movement of the second star also causes a twist of the first star. To support the transport of the belt system, the first star can also be in operative connection with the drive.

The rotation of the barrels into their firing position preferably takes place by means of an electric drive, which acts, for example, via an intermediate toothed wheel on a circumferentially integrated toothing of the barrel bundle. The supply and removal (transport) of the belt system can be combined with this drive. The ammunition is ignited by at least one firing pin in the lock in a known manner. The belt system with the ammunition is continuously introduced into the weapon, the respective belt member with the corresponding barrel and the ignition device (firing pin) aligned aligned, the firing pin tensioned and fired the shot. This variant requires a constructive separation of the star and the closure.

In an advantageous embodiment, the closure part of the weapon has a plurality of chambers for receiving a firing pin and is rotated together with the barrel bundle. The triggering of the respective firing pin is done in a simple design with the help of a weapon fixed disc with a cam, which are designed so that they release the aligned in the firing position firing pin and then can transfer this back to the rest position. Also for this purpose, the use of the roller shutter offers.

In order for the weapon system to operate dynamically, it is provided that the belt member, which has the ammunition in the firing position, as well as the shutter a small way or angle is rotated together with the barrel or barrel. This has the advantage that a continuous shooting is possible because no downtime must be observed. During this time, the shot can be fired. For the belt system, a weapon-resistant forced operation can additionally be integrated, which derives the corresponding belt member in the direction of rotation of the associated barrel.

It is therefore proposed a light weapon, in which a belt system or the belt member of this system creates a replacement cartridge storage, so that the belt or the belt member forms the actual cartridge chamber of the weapon. The belt with the ammunition / cartridge contained therein is supported by the weapon or the closure and thereby teilverkammert. The roller shutter itself does not form a complete chamber because a gap is formed by the belt system where the belt passes. This Teilverkammerung is thus slightly open on the sides, but is closed by the belt members. The cartridge bearing formed by the belt member thus forms a barrel or pipe replacement. It is therefore a transportable cartridge chamber. It is functional without the stars as such. It is understood that depending on the caliber size of the material and the size of the belt member and the belt system is to be selected in order to take over the task of a cartridge chamber and to record the propellant charge gases nondestructive. The multi-tube weapon is not only to settle in the small-caliber weapons area (about 9 mm) but also in the medium caliber area.

Reference to a preferred embodiment with drawings, the invention will be explained in more detail. It shows:

1 shows a multi-purpose weapon according to the invention in a perspective perspective view, FIG. 2 shows the multi-movement weapon in a perspective rear view, FIG.

Fig. 3 is a sectional view of the multi-purpose weapon along the ammunition supply in

Section A-A of Fig. 2,

4 is a sectional view of the multi-barrel weapon along the section B-B of FIG. 1,

Fig. 5 shows a possible variant for the rotation of the barrel bundle.

In Fig. 1, a multi-barrel weapon or multi-barrel weapon 1 is shown here with six runs 2. The barrels 2 are in turn rotatably held about a rotation axis D in the form of a barrel bundle 20 in a front weapon part. Furthermore, the weapon 1 is embossed by a preferably electric drive 3. In belt members 4 of the belt feed 5 cartridges 6 (ammunition, projectiles, etc.) are stored or held in this. The belt feed 5 thereby runs into an opening 7 of the weapon 1 and at the preferably opposite opening 8 without bullet 6.2 but in this embodiment with the remaining sleeves 6.1 out again. The weapon 1 has a weapon housing 21 that preferably holds all assemblies of the weapon 1.

The individual belt member 4 can have a non-metallic material as the outer shell 4.1, such as plastic. The inner layer 4.2 of the belt member 4 may consist of copper, brass, steel, titanium, aluminum, etc., ie metallic materials or coatings thereof. The inner layer and outer shell made of a material, for example in the form of metallic material, is also possible.

Fig. 2 shows selbige weapon 1 from the rear perspective. In the rear part of the weapon housing 10, a closure part 9 of the weapon 1 is distinguished. The closure part 9 has in the preferred embodiment, a plurality of firing pin 11, which are aligned in the same number as the gun barrels 2 on this, each gun barrel 2 a firing pin 11 is assigned. The closure member 9 with the firing pin 11 rotates in the same direction with the barrel bundle 20 in the same frequency. In a preferred embodiment, a roller closure consisting of two stars 12, 13 is integrated, the second star 13 and the closure part 9 forming a structural unit. As a result, a secure alignment of the firing pin 11 is possible on the belt members 4, mechanical votes between the second star 13 and the closure member 9 may be omitted.

Fig. 3 shows a section through the weapon 1. Clearly visible, the belt members 4 are guided through the opening 7 in the weapon 1. When the corresponding belt member 4 reaches the predetermined shooting position, a first star 12 and a second star 13 abut the belt member 4. The belt member 4 forms in this situation, the cartridge chamber 22 of the weapon 1. This belt member 4 is supported by the shells 12.1 and 13.1 of the two stars 12, 13 so that the belt member 4 can fully take over the operation of a cartridge chamber.

FIG. 4 shows a further section through the weapon 1. The ammunition or cartridge 6 is brought into alignment with the belt member 4 with one of the weapon barrels or gun barrels 2. The focused on this run 2 firing pin 11 is released and pricks the primer of the cartridge 6 at. The projectile 6.2 leaves the belt member 4 and passes through the gun barrel 2. The respective gun barrel 2 and the belt member 4 and the shutter 9 can move through a small path with each other, which is the recording of the belt member 4 in alignment with the gun barrel 2 and leaving the belt member 4 from the alignment with the gun barrel 2 easier.

The triggering of the firing pin 11 is carried out in a simple embodiment by a ring with cam or clearance (not shown), whereby the firing pin 11 can be stretched as well as released.

Fig. 5 reflects a possibility of rotation of the barrel bundle 20. The drive 3 engages with its gear 3.1 via an additional gear 23 on the toothing 24 of the barrel bundle 20. The barrel beam 20 may be fixed and releasably connected to the star 3 of the roller shutter, this star 13 may alternatively be an integral part of the barrel bundle 20. With the movement of the star 13 not only the shutter 9 is rotated, but also the belt system 5 is pulled into the weapon 1. This is connected in However, rotation of the first star 12 is preferred, with the first star 12 being driven by the external drive 3, preferably even by the gear 23, which rotates the barrel 20.
