The invention relates to an insertion barrel for hunting weapons

for firing small-caliber projectiles from bullet cartridges

§ nen from a barrel of much larger caliber, in particular the shotgun barrel of a shotgun, the insert barrel holding a cartridge case and a ball barrel

The legal hunting regulations and hunting rules provide that different types of game may only be shot with special ammunition - this forces the hunter to procure a number of different hunting weapons and carry them with you when hunting. So-called combination weapons were often used as a remedy made use of several runs. For example, rifle guns each have a shotgun barrel and a bullet barrel, Triplets usually two shotgun barrels and a rifle barrel etc. However, each of these alternatives is still available with a great deal associated with high costs and circumstances. In the past this led to technical development and Introduction of so-called plug-in barrels to equip Hunting weapons, especially with smooth shotgun barrels. For example, from CH - PS 52 4-27 there is an insert barrel known which no facilities for correcting the

Has projectile angle.

Such a correction is desirable and necessary because the trajectory of a long-range spherical bullet is different than that of a shot load. It should also be taken into account that, for example, when inserting] For triplets, a correction of the projectile exit is inevitably necessary because the The axes of the shot barrels of the triplet usually cross at a distance of 6 m.

Most of the known insert runs are therefore with facilities for setting the axis of the barrel bore, the so-called soul axis. For example is known from DE - GM 80 12 499.8 an insert barrel, one end of which is firmly centered in the weapon cartridge chamber is, while at the front end of the barrel an Ex & nterring is rotatably arranged for the purpose of adjustment, which after shooting in and achieving a good hit position with the help of is fixed to the grub screws provided on the ex% nter. This has the disadvantage that as a result of the fixation again a change in the barrel position is brought about, which changes the hit pattern. Another disadvantage is

given by the E ^ enter itself, since its eccentricity unchangeable at least for one and the same E <z "enterring is. The adjustment is therefore difficult and not always possible exactly. Another part of the problem is that the E ^ enterring with a very precise tolerance, for example

be adapted to the diameter of the barrel as a sliding fit r

got to. When inserting the insert barrel can therefore already A grain of dust can scratch the shot barrel. Considerable difficulties in adjusting the insert barrel is also preparing one with DE-GM 80 29 84-4. 8 suggested Version in which one can be pushed over the insert barrel and holds it in the large-caliber barrel Socket with ten radially arranged adjusting screws is provided.

The embodiment of an insert barrel according to DE-OS 25 18 976 shows a fundamentally different arrangement.

This consists of two parts, namely one in the weapon cartridge chamber centered cartridge chamber part and an adjoining barrel part, both through a kind Ball joints are connected to each other. One that crosses the ball joint and is intended to be tightened The clamping nut is extended in the direction of the barrel muzzle and with grub screws to fix the barrel adjustment

provided. A deviation of the firing channel from the Target position of the sighting device of the weapon is adjusted in that after removing the plug-in barrel by means of Hammer blows on the clamping nut transversely to the core axis and / or twisting the grub screws the running part in the desired Direction is brought. The barrel correction is extremely difficult, especially an unwanted one Adjustment, for example due to impact during transport, cannot be ruled out. In addition, the well-known insert barrel is unusually complex. Another disadvantage is with the connection of the Trains are given between the two barrel parts, even with the slightest twist of the barrel part in the ball joint no longer match.

The invention is based on the object of providing an insert barrel that is particularly easy to adjust and reliably secures the set direction of the soul axis. Furthermore, the Einstecklauf should be Plugging in and pulling out ensure the greatest possible protection of the shot barrel, and a certain amount when firing Have a degree of structure-borne sound insulation compared to the shot barrel. The plug-in barrel should ultimately

uncomplicated, robust and at a relatively low cost can be manufactured and used with as many different shotguns as possible without changing them.

The object is achieved with the invention in that the ball barrel is mounted in a receiving tube with a radial distance. | ('arranges and therein in a determining the projectile exit angle , variably adjustable direction of its bore axis is fixed, and that the receiving tube is elastic Support members is centered in the shot barrel.

The inventive arrangement of the barrel in a receiving tube with a radial distance, in which this is fixed after setting its axial direction

. ., a system of barrel and receiving tube is formed

Unit, which allows both a simple adjustment of the running direction as well as a convincingly simple and safe Fixation allowed. Due to the fact that the receiving tube is centered in the shot barrel via elastic support members, is achieved with extreme care of the same both an extremely precise centering and a firm hold, with Nevertheless, the barrel can easily be inserted and removed by hand without the use of tools or other aids.

can be built. The resistance of the elastic support members prevents the in the inserted state of the Insertion barrel when opening the weapon and pulling out the cartridge case an independent pulling out of the complete Insert barrel.

Above all, however, the pretensioning of the elastic support members between the insert barrel and shot barrel creates a transmission prevents the structure-borne sound waves of the barrel from affecting the other parts of the weapon. This is a very important advantage, especially when the barrel is off-center in one of two Twin runs lying next to one another are perceived as pleasant.

One embodiment of the invention provides that the ball barrel and the receiving tube are connected to one another via the cartridge case, while the muzzle of the ball barrel after setting the direction of its bore axis by a device for adjusting and fixing opposite the receiving tube is braced.

This results in the advantage that these two main elements of the insertion barrel are neither in the axial direction against each other shifted or twisted against each other

can. This means that the set adjustment is optimal secured.

The actual means for adjusting is undsur 'i fix the ball run extremely easy and it sure as it is essentially formed <radially to the axis of the receiving tube disposed therein adjusting screws.

As is known, these are arranged in a circle of 120 ° to the three-point support of the circumference of the barrel. This also makes the barrel, which is exposed at the front, easier to stretch when the barrel is heated made possible in an effective way.

In order to support the fixed position of the barrel and to prevent vibrations of the barrel or the receiving tube, a further embodiment provides that an annular gap is formed in the radial distance between the ball barrel and the receiving tube, and that at least one elastic support member is arranged in this is, preferably in a Fom binges of elastic material ₄ whose profile a slight oversize compared to the annular gap * t

At the same time, the annular gap between the barrel and [

Mounting tube for unhindered stretchability of the barrel in the event of heating and prevention of heat transfer to surrounding parts of the weapon.

Both easy insertion and removal of the barrel by hand, as well as a secure hold in of the weapon, extremely precise centering and extreme protection of the shot barrel are achieved as a result, that the receiving tube and the cartridge bearing sleeve connected to it have an annular gap at a radial distance from the shot barrel and the cartridge chamber, and that the receiving tube and the cartridge bearing sleeve on their outside in recesses inserted support members in Have the form of elastic rings, the outer diameter of which is slightly larger than the inner diameter of the shot barrel or the cartridge chamber. The oversize of the elastic rings is approx. 0.2 mm. Through this this has the advantageous effect that when the complete plug-in barrel is inserted into the shot barrel, the plastic / rubber rings, which are arranged on the receiving tube and the cartridge bearing sleeve, firmly press in,

An expedient and uncomplicated manufacture of the insert barrel is ensured by the fact that the ball barrel soldered into the cartridge case and the receiving tube is screwed to the cartridge case. In order to save weight with simultaneous stability it is further provided that the receiving tube is preferably made of aluminum Made from a corrosion-resistant, high-strength duralumin alloy.

Due to the known design of the cartridge bearing sleeve by means of a protruding, preferably conical Edge in the appropriately elaborated cartridge chamber of the shot barrel is also an exact centering of the Plug-in barrel supports and also causes the * The entire barrel cannot be moved forward when firing. To ensure an evenly - full system of the conical To ensure edge dep cartridge case, and at the same time also a structure-borne sound insulation when firing to achieve in the direction of recoil, provides a design of the buttstock of the cartridge case that it has two short holes parallel to the axis of the barrel, which are lined with plastic pins.

are filled, which are about 1/2 mm above the bottom of the Survive insert barrel.

This has the advantage that when the closure is closed by the protrusion of the plastic pins an even pressure is always exerted on the male barrel in the direction of its mouth. This will make the even centering is further secured and a constant shooting performance is achieved.

In order to prevent damage to the male barrel muzzle, according to a further embodiment, the receiving tube is on the mouth of the barrel protruding over this, and there with a preferably conical mouth? - protective sleeve Mistake.

And finally, it is provided that an extractor for cartridge cases is arranged in the cartridge case.

A major advantage of the insert barrel according to the invention

It is evident from the fact that it is elastic due to its elasticity Storage and the associated favorable properties in existing triplets and / or over and under rifle shotguns can be easily installed without any changes to these monkeys.

In the following the invention is explained in more detail with reference to exemplary embodiments in the drawing. Show it :

Figure 1 shows the mouth of an insert barrel according to the invention , seen from the side, partly in section along section line I-I according to FIG. 3, partly in view, inserted in a shotgun barrel also shown in section;

FIG. 2 shows a rear part of the insertion barrel in the area of the cartridge case, seen from below in the cut chamber of the shotgun;

FIG. 3 shows a section through the mouth area the section plane III-III according to FIG. 1;

Figure 4 is a view of the insert barrel and the surrounding Chamber of the shotgun, looking towards the bottom of the chamber case.

Figure 1 shows the mouth-side part 1 of the insert barrel 2. According to the invention, the insertion barrel 2 consists of the ball barrel 3 and the receiving tube 4 and the cartridge case 5 together. The bore axis B of the ball barrel is inside the receiving tube 4 in the mouth part 1 Fixed in a direction determining the projectile departure angle by the adjusting screws 6. The receiving tube 4- and the cartridge bearing sleeve 5 connected to it is over elastic support members 7 in the shot barrel 8 safe and reliable centered. This ensures that the imaginary center axis of the receiving tube with the soul axis of the Shot barrel exactly match, while the necessary difference in direction between the soul axis of the shot barrel 8 and the bore axis B of the ball barrel 3 exclusively through the bracing via the adjusting screws 6 is made within the receiving tube 4 ·. The legal

animal screws 6 allow a quick and very fine adjustment of the barrel. For example, a quarter turn of an adjusting screw is used in the
Hit pattern reached a deviation - / of 10 cm in any desired direction. This adjustment is also facilitated by the fact that the ball barrel 3 ^and the receiving tube 4- are firmly connected to one another via the cartridge case.

This causes mutual movement of the barrel 3 and

and adjusting the two adjusting screws 6, a correction of the projectile exit angle is achieved. Through this a problem-free and quick sighting in of the insert barrel is achieved. The ones used as elastic support members Rubber or plastic rings 7, 10, 10 'are like that sized so that they each have a slight excess

C to the internal diameter to accommodate them, namely

this oversize is uniformly approx. 0.2 mm. It is thereby achieved that is insert barrel 2 on the one hand absolutely safe centered in the shotgun barrel 8 is seated, on the other hand he finds a sufficiently secure axial retention therein, yet inserted by hand without the use of tools or other aids and / or can be pulled out. To do this, the non-displaceable rings 7 on the circumference of the receiving tube 4 and the

• - _t cartridges bearing sleeve 5 securely hold zn, these are inserted into grooves on the 11th In the interests of a balanced production option and for problem-free assembly and / or disassembly, provision is made for the ball barrel 3 to be soldered into the cartridge bearing sleeve 5, while the receiving tube is screwed in by means of a thread 12. To save weight, the latter is made of light metal. A corrosion-resistant, high-strength duraluminium alloy is expediently provided for this purpose. The cartridge bearing sleeve 5 has the type of a cartridge

protruding edge 13, with which they are in a corresponding Turning 14- of the cartridge chamber 15 centering inserts · The chamber 15 is part of the shot barrel 8 · Through the conical edge 13, the insert barrel 2 set both in the axial direction and when closing the shutter (not shown) by means of

axial pressure held securely in the centering position. This axial pressure is generated in that two bores 17 are provided in the butt plate 16 of the plug-in barrel 2, into which plastic pins 18 are embedded, which protrude about 1/2 mm in the direction towards the closure over the butt plate 16. When the breech is closed, these lie firmly against it and in this way cause the said pressure against the butt plate 16 in the direction of the barrel muzzle 19. As a result of their damping material property C · as plastic pins, they produce a very advantageous shock-absorbing effect compared to the recoil when firing. In this way, however, the absolutely exactly uniform centering, which has already been brought about by the elastic rings 7, is further supported, and thus a uniform shooting performance is achieved * |

As FIG. 2 further shows, an extractor 20 is housed in the cartridge chamber * 5 * which ejects the cartridge case after the shot when the breechblock is opened. ^l

As can still be seen from FIG. 1, the receiving tube is standing 4- at the mouth 19 of the ball runner 3 over this

and is provided at this point with a preferably screwed-in conical muzzle protective sleeve 21. This embodiment is a further advantage over known Einsteckläufen _t because it allows the Beschäligung or clogging of the orifice is prevented 19th

FIG. 3 shows a section corresponding to the section plane III-III / - In Figure 1 the arrangement of the individual elements of the insert barrel . Identical parts are provided with the same reference numerals, which is why following the preceding description no further explanation is required. A front aiming device 22 attached to the shot barrel 8 with the so-called Grain 23 can be seen from FIG. Figure 4- shows the bottom 16 of the cartridge bearing housing 5 with the plastic pen 18. FIG. 4 also shows the arrangement of the extractor 20

From the representation of the embodiment of a plug-in barrel 2 according to the invention it can be seen that the invention solves the problem in an optimal way: this can be adjusted, pulled in and out by hand, in particular without tools or aids, protects the shot barrel Considerable insulation and damping properties, is uncomplicated, accurate in continuous operation, and can be used for different shotguns without changing the weapon. / ^ 'iwmww ^ r ■ V ν— ^:
