Description

The invention relates to a signature and silencer on firearms.

Silencers on firearms are for noise reduction (health protection of the user), better communication among each other and signature reduction to reduce the detectability of the shooter, the current state of the art for special operations, snipers and hunters in the civilian sector. The muzzle blast can only be dampened by relaxing and cooling the high-pressure shot gases as they leave the muzzle in correspondingly long and voluminous damper housings.

In order to reduce the disadvantages of the additional mass, the silencers are usually designed to be removable.

That's what the patent says DE 100 02 374 C1 a holder for attaching a silencer to the barrel of a handgun is known, with an essentially tubular silencer, a mounting base attached to the rear end of the silencer and a barrel muzzle adapted to the mounting base, on which the mounting base can be fastened, the barrel muzzle having a non-round configuration, a complementary part is provided on the mounting base with a counter-design complementary to the non-round design, so that the complementary part can only be fastened in a predetermined angular position on the muzzle, the silencer is attached such that it can rotate with respect to the complementary part, and a locking device is provided which secures the silencer on the complementary part in a selected rotational angle position non-rotatably.

The patent also discloses DE 199 35 929 C1 a bracket for attaching a silencer to the barrel of a handgun, with a retaining lug which is attached or formed on the silencer and which has a centering bore arrangement, a mating lug which is attached or formed on the barrel and has a central mating surface arrangement which fits into the bore arrangement , and a releasable lock for fastening the holding attachment on the counter attachment, wherein the bore arrangement and the mating surface arrangement are seated in a centering manner in a seating zone, and at least one expansion space is formed between the two axial ends of the seating zone.

It is also known that silencers can be attached not only exclusively to the end of a gun barrel, but also to other firearm devices. This is what the disclosure document reveals DE 10 2011 010 639 A1 a silencer for a handgun, in particular an assault rifle or another long weapon, with a silencer that can be placed on the weapon barrel, characterized in that a muzzle brake is attached to the weapon barrel and can be connected to the silencer via a screw connection.

The disadvantage of this embodiment is that the weapon becomes longer by the dimensions of the silencer and the center of gravity of the weapon shifts towards the front end of the barrel.

In order to avoid this disadvantage, "overbarrel" dampers were developed, which to a certain extent reduce the increase in length of the dampened weapon by not completely protruding with their damper housing over the barrel muzzle, but also covering part of the barrel.

Lastly, structurally silenced weapons for the subsonic range are known, which, however, are only designed for a very specific area of application and also correspondingly reduced operational ranges.

So is from the US patent specification U.S. 8,857,307 B2 a method for producing a long gun with a silencer is known, which describes the production of a hood around a gun barrel in four steps.

The disadvantages of these known solutions are that the handling is significantly restricted by the shift in focus, the top-heaviness of the weapon often leads to a change in the point of impact and thus makes it necessary to shoot again when changing. Structurally silenced weapons for the subsonic range are only designed for a very special area of application and also correspondingly reduced operational ranges.

The object of the invention is therefore to present a signature and silencer that has a reduced overall length compared to conventional weapons with attached silencers, is adaptable and has an increased volume for improved sound absorption.

This object is solved by the characterizing features of the main claim. Advantageous configurations are described in the dependent claims.

The advantage of the weapon silencer according to the invention is that the silencer tube is arranged coaxially, largely around the weapon tube. The position corresponds to that of a tubular jacket damper, but the damper tube is detachably connected to the weapon.

A further advantage is that the damper tube is supported on the barrel of the weapon via a counter bearing. On the one hand, the design of the damper tube is no longer self-supporting in this case and can be simpler and lighter. On the other hand, the damper tube helps to suppress running vibrations when attached.

On its inner cross section, the counter bearing advantageously has a clamping device, such as a cone or a clamp, with which the counter bearing is fastened gas-tight to the gun barrel. Of course, inserts in the counter bearing are also conceivable which have a clamping device for different weapon barrel geometries and cross sections.

A further advantage of the invention is that the counter bearing has a centering device such as a cone, a groove or a thread, via which the damper tube is detachably connected to the counter bearing. This creates a vibration-free, position-centered, detachable connection that can be removed for transport, for cleaning purposes, or when not in use. The clampable counter bearing also has the advantage of being able to accommodate damper tubes of different lengths. The longer the damper tube is chosen, the greater the signature and sound damping.

The backward position of the silencer tube makes it possible to use a second silencer for optimal noise and signature reduction. The muzzle adapter has a corresponding thread. If no additional damper is used, the weapon silencer according to the invention shortens the overall length of the weapon in relation to weapons with conventionally screwed-on silencers and has a positive influence on the shift in the center of gravity through the screwed-on silencer. In addition, depending on the barrel length, a longer damper tube can be used, which increases the damping performance and reduces barrel vibrations.

The muzzle adapter is adapted to the thread on the barrel end of the weapon. The adjustment is made via a coordinated spigot, which has the counterpart of the two threads. With exact tuning, the muzzle adapter clamps the damper tube between the muzzle adapter and the counter bearing when screwing on.

If the muzzle adapter combines the two functions - screwing onto the gun barrel and centering the damper tube at the same time - the centering device is designed as a cone. By unscrewing, the distance between the centering device of the muzzle adapter and the centering device of the counter bearing, which is firmly clamped onto the gun barrel, is reduced. The centering device of the muzzle adapter moves into the muffler tube until the cross-section of the muffler tube is in gas-tight contact with the cone. This advantageous embodiment is described in dependent claim two.

High gas pressures can cause the damper tube to expand, which breaks the positive, gas-tight connection to the centering device. The use of a compression fitting as a centering device for the muzzle adapter connects the muffler tube to the muzzle adapter with a thread and seals the muffler tube to the muzzle adapter using a vibration- and cross-section-tolerant seal. This advantageous embodiment is described in dependent claim three.

A further advantageous embodiment of the invention is described in dependent claim four. The muzzle gas bores in the muzzle adapter are arranged at an angle of between 15° and 45°, particularly advantageously 30°. After the bullet has exited the muzzle adapter, the shot gases flow in the direction of the adapter opening and reduce the escape of shot gases from the case ejection window on the shooter's side and thus the exposure to harmful substances for the shooter.

Depending on the design of the weapon, the damper tube can have different geometries. For example, an oval shape or a conical shape or combinations of different shapes are possible. Common to all damper tubes is that they rest gas-tight or are detachably connected with a first open end in a centering device of the counter bearing and rest gas-tight with a second open end in a centering device of the muzzle adapter or are detachably connected. The use of a cylindrical, rotationally symmetrical damper tube is the simplest form. This advantageous embodiment is described in dependent claim five.

The following functional sequence is described for better understanding. First, a counter bearing is clamped gas-tight onto the gun barrel at a predefined distance from the end of the barrel. A damper tube is placed or detachably connected to the centering device of the counter bearing. The muzzle adapter is screwed onto the rifle barrel and stretches over the damper tube the centering devices between the muzzle adapter and counter bearing in a gas-tight manner. Alternatively, the muzzle adapter is screwed onto the gun barrel and then the centering device of the muzzle adapter is screwed into the damper tube and then clamped onto the muzzle adapter. When the bullet passes through, the high-pressure shot gases are guided through the muzzle gas bores into the damper tube, where they are relaxed and cooled. By setting the muzzle gas bores at an angle of 30°, the effect of a smoke evacuator is created, which leads to reduced smoke gas extraction during case ejection and thus to reduced pollution for the shooter.

It shows the only one 1 a weapon silencer according to the invention in a lateral sectional view.

It shows the 1 a muzzle adapter 1, which has a Borelock thread 2 in the front peripheral area for use with a further silencer. For attachment, the muzzle adapter 1 is provided with a wrench flat 3 which is matched to a corresponding wrench size. The muzzle gas bores 4 are attached at an angle of about 30° and direct the high-pressure shot gases into the damper tube 5 as the bullet passes through. A first end of the damper tube 5 is connected to the counter bearing 8 with the aid of a truncated cone-shaped centering device and a thread. The connection is realized via a crimped connection 10 .
