Description

BACKGROUND OF THE INVENTION

TECHNICAL AREA

The invention relates to a hunting firearm with a locked silencer, the butt stock can be folded laterally and can be fastened to the forearm in the folded state, and a set comprising a hunting firearm according to the invention and an additional muzzle bush.

STATE OF THE ART

Firearms with a folding stock have long been known, as early as 1830 the Italian gunsmith family Mutti manufactured a foldable travel rifle with a percussion ignition. Folding stocks are also very common for military rifles, such as the HK 433 assault rifle from Heckler and Koch, Oberndorf.

The muzzle blast of firearms can be greatly reduced by using silencers. Undamped, the sound pressure level of the muzzle bang is so high that it is far in the area of health damage to human hearing. To avoid hearing damage, hearing protection must be worn without using a silencer.

With a special form of hunting, namely the search for welded - shot game, wearing an ear protector is impractical. This can not only easily slip or be stripped in the thick undergrowth and therefore does not protect safely, but also worsens the acoustic perception of the environment. Directional hearing in particular suffers, but so does the estimation of the distance to the noise source. The use of a silencer on a firearm used for the search is therefore obvious. For the dog used in the search, a silencer is also the only way to protect his hearing from the muzzle blast.

So far, however, the use of silencers within the scope of the search has only been possible with restrictions: During the search, which often leads through dense undergrowth, the clothing and equipment that is carried along must offer few points of attack in order to get caught in the vegetation. This need is reflected in a large number of special search rifles available on the market, such as the "driven hunt and search rifle" with the name "Silverhunter" from Stegmann Waffen Handel, Mainhausen. This has a comparatively short barrel to keep the overall length of the weapon small. In addition, this weapon also offers a mounting option for the strap in the immediate vicinity of the muzzle. This enables a way of carrying, in which the barrel does not protrude above the strap and thus offers considerably less contact surface for hanging in thick vegetation, as would otherwise be the case with a conventional hunting weapon.

If a muffler is now attached to the weapon, it usually extends the weapon by about 20 - 25 cm, depending on the product. This protrusion protrudes completely beyond the end of the strap attached to the mouth, making it considerably more difficult to move forward in the thick vegetation. Even silencers that extend part of their body backwards over the barrel and therefore have a shorter overall length (so-called "overbarrel" damper) still extend the weapon by approx. 15 - 20 cm, are unable to solve this problem, because the sling eyelet on the barrel has to be moved far back to provide space for the damper. In any case, the muffler protrudes around the mouth end of the strap by orders of magnitude of around 20 centimeters. This makes the use of a muffler impractical for search guides. Since the need to fire a shot is often time-critical due to the highly dynamic situation, unscrewing the muffler or putting on ear muffs just before the shot is not a practical solution.

The utility model DE 20 2015 008 335 U1 suggests fitting the muffler with a strap for the strap.

However, the screwed-on silencer must completely absorb the forces that occur when the weapon is carried in the form of torsional, tensile and buckling forces.

These forces are fully absorbed by the barrel thread of the weapon, which in the long run leads to excessive thread wear.

The German patent application DE10 2016 107 806 A1 relates to a self-loading pistol with a frame which has a shoulder rest, which can also be folded laterally via a hinge.

The US patent application US 2011/0107 644 A1 also proposes an adapter for a pistol, which the pistol with a Provides shoulder rest. Here, too, the shoulder rest can be folded away laterally through the joint.

The US patent application US 2015/0267 977 A1 describes a rapid-fire rifle of the Kalashnikov type "with a foldable shoulder rest

None of the weapons with a foldable shoulder rest disclosed in these patent applications have a locked silencer. It is also a pistol or a rapid-fire rifle that is not suitable for press-hunt or search-for-hunting with a hunting dog.

The present invention was based on the object of providing a hunting firearm with a silencer which avoids the disadvantages of the prior art and enables a handler to search in the thicket with the dog without running the risk of dealing with the barrel, the silencer or tangle the butt of the rifle in the undergrowth.

This object has been achieved by the present invention.

DETAILED DESCRIPTION OF THE INVENTION

The hunting firearm according to the invention is a rifle with a drawn barrel, preferably a self-loading rifle with up to three loaded cartridges, a shotgun, a long gun designed as a barrel-barrel weapon or a repeating rifle, in particular a repeating rifle.

The term “silencer” as used before and below denotes a muzzle signature reducer for reducing the noise emissions of the hunting firearm according to the invention. The interior of the muffler preferably has components that inhibit the flow of the propellant gases. These can be pierced baffles, chambers or other, usually inclined or spirally arranged components.

The term "locked" or "lockable" as used in relation to the silencer or the muzzle bushing before and after, denotes the type of attachment of the silencer or the muzzle bushing to the barrel. In contrast to a muffler that is conventionally only screwed on, it is screwed onto the barrel according to the invention and additionally detachably fastened by a locking device.

The muffler or the alternative muzzle bushing is preferably able to be locked on the barrel of the weapon, for which purpose a bore with a diameter of 3.0 to 5.0 mm, in particular 4.0 mm, on the rear end face thereof or alternatively a milled longitudinal slot 3 mm wide and 3.0 to 4.0 mm deep.

There is preferably a clamping ring on the barrel, which can be loosened by means of a screw or toggle screw and adjusted to the respective position.

This clamping ring has either a spring-loaded or firmly inserted bolt with a diameter of 3.0 to 5.0 mm, in particular 4.0 mm, or a rail with a thickness of 2.7 to 2.9 mm and a height of 3.0 - 3 , 5 mm. Alternatively, this locking mechanism can also be installed on the grain base, which is screwed and glued to the barrel of the weapon. This can preferably be moved by hand. For this purpose, a slide is attached to the grain base, which can be operated by hand for locking and unlocking.

According to the invention, the sling swivel is not, as usual, on the barrel of the weapon, but in the muzzle area of the muffler or the alternative muzzle bushing.

The strap bracket is preferably a mounting option for a carrying strap that is to be retrofitted to the locked silencer. This can be placed around the damper as a ring or clamp that is matched to the outer diameter of the muffler or the muzzle bushing and can be fastened by clamping using one or more screws or a quick-release fastener. The attachment of the belt can be carried out in the form of a fixed or rotatable strap bracket as: fixed or rotatable strap bracket eyelet for receiving a strap bracket or a fixed or rotatable interface for receiving commercially available or custom-made strap brackets or strap bracket eyelets, e.g. B. in the form of a short piece of profile rail (z. B. Picatinny rail) or a socket for receiving detachable strap clips or strap clip eyelets.

Alternatively, the strap bracket can also be attached to the side of an open muzzle cap of the muffler or the muzzle bushing.

The locking of the muffler or the alternative muzzle bushing enables the strap bracket to be attached in the muzzle area, preferably at the muzzle end of the muffler.

1. (a) it is a repeating rifle with a chamber stem, the fold-out butt stock having a recess which receives the chamber stem in the folded state;
2. (b) the fore-end is hinged to the buttstock on the pistol grip;
3. (c) the hinge can be opened by actuating a spring-loaded button;
4. (d) the pistol grip and / or the fore-end have a locking pin in which the folded-in buttstock can be releasably locked;
5. (e) the strap bracket is fastened in the mouth region, preferably at the mouth end of the muffler;
6. (f) the muffler has an internal recess in its mouth area or a bushing mounted centrally on the muffler side of the muffler for receiving a round plastic plate as muzzle protection, the plastic plate preferably having a thickness of 0.10 to 1.00 mm and a diameter which is larger than the inside diameter of the barrel of the weapon.

In the case of very thin-walled silencers, an internal puncture cannot be implemented. In this case, a bushing with a diameter of D 20 - 25 mm is attached to the center of the muffler. The socket is preferably screwed on with two countersunk screws M 4 or M 5. The puncture for the muzzle plate is then introduced into this socket. This also effectively protects a thin-walled silencer from the ingress of dirt and water.

This protects the muzzle of the hunting firearm from the ingress of dirt, water or snow. In the worst case, contamination in the barrel can lead to very dangerous weapon explosions.

In the previously known systems, a muzzle guard is inserted into the barrel.

Due to the recess in the inside of the muffler's mouth, an approximately 0.1 - 1.00 mm thick round plastic plate can be pressed in from the front. This flies away through the air column created in front of the bullet before the projectile itself reaches the muzzle. Again, the tile has no effect on the precision of the weapon. The muffler and the barrel are thus effectively protected against dirt.

The silencer ( 2nd ) is at the front end of the barrel ( 11 ) locked. With the help of the hinge ( 3rd ) the butt stock ( 4th ) fold down to the side, the chamber stem ( 7 ) from the in the buttstock at the level of the upper part of the pistol grip ( 6 ) recess ( 8th ) is included. The locking pin ( 10th ) into the locking device ( 9 ), whereby the folded buttstock is attached to the forearm. In this configuration, the hunting firearm according to the invention is suitable for carrying in the undergrowth, the carrying strap being attached to the strap bracket integrated in the hinge ( 16 ) and one in position ( 4th ) of the silencer ( 2nd ) attached, not shown sling bracket is attached.

The lock can be activated by pressing the spring-loaded button ( 15 ) can be loosened again, whereupon the buttstock can be opened again and due to a snap mechanism of the hinge ( 3rd ) is fixed in the unfolded form, and the hunting firearm can be used for shooting.

There is a puncture in the mouth of the silencer ( 17th ) for holding plastic plates as muzzle protection. In an alternative embodiment, a metal ring or a plate can also be placed on the mouth for fastening the plastic plates.

The hunting firearm ( 1 ) with the buttstock folded out ( 4th ) and the locked silencer ( 2nd ) ( 1 ) with a weight of 3,300 g a total length of 110 cm. With the buttstock folded in ( 4th ) and the locked silencer ( 2nd ) ( 2nd ) it has a total length of 76.5 cm. Without a silencer, the weapon weighs 2,900 g and is each about 15 cm shorter.

The length of the barrel ( 11 ) is 42 cm.

Despite the locked silencer, the weapon can still be used with a rear sight ( 12th ) and grain ( 13 ) are shot. This is not possible with many other weapons with silencers, and it can only be shot through an optical system (riflescope or red dot sight).

3rd and 4th show representations of an embodiment of the hinge ( 3rd ) from different perspectives. The hinge is made of a metallic material, especially stainless steel, and is color-matched by coating the weapon. The hinge ( 3rd ) includes a hinge plate ( 31 ) on the forend ( 5 ) is attached and a hinge plate ( 32 ) on the buttstock ( 4th ) is attached. With the help of 2 cylinder pins ( 37 ) rotatably attached chain link ( 33 ) the hinge can be opened and closed. The dimension and geometry of the surfaces of the two hinge plates ( 31 , 32 ) corresponds to the dimensions of the respective surfaces of the ends of the front and rear stock to be connected ( 4th , 5 ).

The hinge ( 3rd ) preferably has a width of 37 to 42 mm, in particular 38 to 40 mm, particularly preferably approximately 39 mm. The hinge ( 3rd ) furthermore preferably has a height of 38 to 43 mm, in particular 39 to 41 mm, particularly preferably approximately 40 mm.

The hinge plates ( 31 , 32 ) each have a thickness of 3.8 to 4.3 mm, in particular 3.9 to 4.1 mm, particularly preferably of about 4.0 mm.

Another cylinder pin ( 37 ) held snappers ( 34 ) grips due to the spring ( 36 ) in the front hinge plate ( 31 ) and fixes the two hinge plates on each other plane-parallel. By actuating the snap head ( 35 ) this fixation is released and the hinge can be opened

5 and 6 show representations of an embodiment of the locking mechanism ( 9 ) for fastening the folded butt stock ( 4th ) on the forend ( 5 ) from different perspectives.

In the housing ( 91 ) of the locking device there is a locking slide movable in the vertical direction ( 92 ) which, with the help of the actuator ( 93 ) against the force of the spring ( 94 ) can be pushed down. The dimensions of the housing ( 91 ) depend on the location of the butt stock ( 4th ) into which it is inserted. The housing preferably has a height of 25 to 35 mm, in particular of approximately 30 mm, a width of 22 to 28 mm, in particular approximately 26 mm and in the upper region a depth of 8 to 10 mm, in particular approximately 9 mm, and in the lower area a depth of 15 to 20 mm, in particular of about 18.5 mm.
