Description

field of invention

The invention relates to a silencer for a handgun and a handgun with a silencer according to the invention.

Background of the Invention

The term "handgun" is understood to mean handguns, such as recoil-operated weapons, gas-operated weapons, pistols or the like. The invention is described using a pistol as an example, although the present invention is not limited to this and can be used with all types of handguns that have a breech or a breech block.

It is known to equip pistols with a silencer in order to reduce the noise emitted by the high-pressure and explosively expanding gases escaping from the muzzle when the gun is fired.

Silencers can be screwed onto the gun barrel via a screw thread at the front end of the gun barrel. Such a muffler is, for example, from DE 4231183 C1 known.

On fixed-barrel handguns, the silencer poses little problem as far as the weapon's self-loading function is concerned.

In the case of handguns with a movable barrel, maintaining the weapon's self-loading function proves to be problematic. Because a silencer screwed onto the barrel increases the mass recoiling when the shot is fired, which reduces the recoil speed of the barrel. This can result in the weapon not being fully self-loading, or in malfunctions, for example because a new cartridge is only incompletely fed. This proves to be particularly problematic with firearms with a receding and tilting barrel, because here the silencer also has to be raised.

In practice, attempts have been made to solve this problem by using lighter or smaller silencers. However, this has the disadvantage that the stability of the muffler decreases with correspondingly light mufflers and that with smaller mufflers the damping effect is sometimes considerably reduced, since only a smaller volume is available for the gas expansion.

A solution to this problem consists in not rigidly connecting the silencer and the gun barrel to one another, but rather arranging a so-called pulse generator between the silencer and the gun barrel, which is connected to the silencer on the one hand and to the gun barrel on the other. The pulser allows axial movement of the gun barrel relative to the silencer. The gun barrel is mechanically decoupled from the silencer with the pulse generator, so that the self-loading function of the firearm is largely guaranteed in spite of the silencer.

However, the use of pulse generators has the disadvantage that they easily become soiled and/or damage to the threads of the pulse generator can impair the function of the firearm. In addition, when using pulse generators with gun barrels that tilt at the rear, the silencer must be raised at the front, with the additional weight of the pulse generator being added here.

From the U.S. 2017/205173 A1 a silencer for a handgun, in particular a pistol, is known, the end section of the silencer facing the weapon barrel being adapted to be attached to the barrel of the handgun.

From the DE 10 2013 107 115 A1 and from the DE 10 2015 122 091 A1 each silencer for a weapon, in particular a handgun, are known, which are adapted to be attached to a mounting rail running below the barrel.

object of the invention

The object of the invention is therefore to provide a silencer for a handgun which, on the one hand, enables the silencer to be easily installed or removed from the handgun and, on the other hand, can also be used in handguns with a self-loading function or with a movable barrel without the Self-loading function is impaired.

Solution according to the invention

According to the invention, this object is achieved by a silencer for a handgun, in particular a pistol, and by a handgun with a silencer according to the invention according to the independent claims. Advantageous refinements and developments of the invention are specified in the respective dependent claims.

Accordingly, a silencer for a handgun, in particular a pistol, is provided, with the end section of the silencer facing the barrel of the handgun being adapted to be attached to the breech block (also called breech or slide) of the handgun.

This enables the silencer to be attached to the handgun without it having to be attached to the gun barrel itself or coupled to the gun barrel. The gun barrel can thus move independently of the silencer relative to the silencer. The silencer only has to be attached to the breech of the handgun.

In an advantageous embodiment of the invention, the silencer or the end section of the silencer can be detachably fastened to the breech block of the handgun. This allows the silencer to be removed from the breech block or the weapon when not in use.

Fastening means can be arranged or can be arranged on the end section of the silencer, or the end section can be designed as fastening means, the silencer being able to be fastened to the breech block of the handgun with the fastening means. The fastening means or the end section of the silencer are structurally adapted to the closure piece, i.e. the fastening means are designed accordingly depending on the specific design of the closure piece.

In one embodiment of the invention, the silencer can be moved with the breech block of the handgun along the longitudinal axis of the gun barrel relative to the gun barrel. This means that when the breech is moved backwards, the silencer is also moved backwards accordingly.

In the silencer, which has a silencer housing and the end section, a firing channel is provided which corresponds to the firing channel of the gun barrel.

• der dem Waffenlauf der Handfeuerwaffe zugewandte Endabschnitt des Schusskanals des Schalldämpfers und
• die dem Waffenlauf der Handfeuerwaffe zugewandte Schusskanalöffnung des Schalldämpfers

so ausgestaltet sein, dass

• das vordere Ende des Waffenlaufs und die Schusskanalöffnung beim Bewegen des Schalldämpfers mit dem Verschlussstück miteinander in Eingriff bringbar sind und
• der in die Schusskanalöffnung eingreifende Abschnitt des vorderen Endes des Waffenlaufs in dem Endabschnitt des Schusskanals frei bewegbar ist.

In one embodiment of the invention

• the end section of the firing channel of the silencer facing the barrel of the handgun and
• the firing channel opening of the silencer facing the barrel of the handgun

be designed in such a way that

• the front end of the gun barrel and the firing channel opening can be brought into engagement with one another when the silencer is moved with the breech block and
• the section of the front end of the weapon barrel engaging in the firing channel opening is freely movable in the end section of the firing channel.

This ensures that when the silencer moves relative to the weapon barrel, the weapon barrel does not collide with the silencer or the movement of the weapon barrel is not impaired by the silencer. Another advantage is that by moving the silencer relative to the gun barrel after a shot has been fired, the front end of the gun barrel protrudes into the firing channel opening of the silencer, so that the escape of explosive gases in the area between the firing channel opening and the front end of the weapon barrel is reduced.

In one embodiment, the silencer can be designed in such a way that the front end of the gun barrel, when the silencer is mounted, also protrudes into the firing channel opening of the silencer when no shot is fired. When a shot is fired, the silencer moves backwards, so that the front end of the gun barrel is then moved even further into the firing channel opening of the silencer.

• einen Magnet, der einem Endabschnitt des Schalldämpfers angeordnet ist und mit dem Verschlussstück oder mit einem am Verschlussstück angeordneten Gegenmagneten zusammenwirkt, oder
• einen Mitnehmer, der vorzugsweise lösbar am Verschlussstück anordbar ist, wobei der Mitnehmer
• einem Endabschnitt des Schalldämpfers angelenkt ist, oder
• mittels Schnellverschlussmittel mit dem Endabschnitt des Schalldämpfers lösbar koppelbar ist, wobei die Schnellverschlussmittel vorzugsweise zumindest eines aus der Gruppe umfassend Schwalbenschwanzverbindung, Schraubverbindung und Bajonettverschluss umfassen.

In one embodiment of the invention, the fastening means can include:

• a magnet which is arranged in an end section of the muffler and interacts with the closure piece or with a counter-magnet arranged on the closure piece, or
• a driver which can preferably be arranged releasably on the closure piece, the driver
• is articulated to an end portion of the muffler, or
• can be releasably coupled to the end section of the silencer by means of quick-release fasteners, the quick-release fasteners preferably comprising at least one from the group consisting of a dovetail connection, a screw connection and a bayonet connection.

This enables a particularly simple and quick assembly and disassembly of the silencer on the closure piece.

In one embodiment of the invention, the end section of the muffler can be designed as a profile that protrudes axially on the muffler housing, with the inner profile of the profile largely corresponding to the outer profile of the closure piece. The inner profile of the profile can have a substantially U-shaped form. In any case, the profile is open on one side. By adapting the inner profile of the profile to the outer profile of the closure piece, the silencer can be pushed onto the closure piece with its end section. Either the silencer can be pushed onto the breech from the front, i.e. along the longitudinal axis of the breech. Alternatively, the end section of the silencer can be slid onto the closure piece from above, i.e. along a transverse axis of the closure piece.

Locking means can be provided in the profile, with which the silencer can be locked on the closure piece.

In one embodiment of the invention, these locking means can include magnets, latching means, eccentric levers and locking rockers. Alternatively, sliding pins can also be provided, which can be moved in the radial direction.

In one embodiment of the invention, the muffler housing and the axially protruding profile can be designed in one piece or in one piece. One-piece or one-piece design means that the muffler housing and the profile consist of one piece or are made of one piece, or that the muffler housing and the profile are made of two parts separately and then joined together in such a way that they are largely non-destructive can be separated from each other.

In one embodiment of the invention, the muffler housing and the profile can also be designed in two parts, with the profile being able to be arranged detachably on the muffler housing. Different profiles can thus be fastened to the silencer housing, if necessary, so that the silencer housing can be fastened to handguns with differently designed breech blocks.

The invention also provides a handgun, in particular a pistol, with a silencer according to the invention.

Detailed description of the invention

The silencer according to the invention described below has the advantage that it can be attached or assembled and disassembled particularly easily and quickly, in particular without screwing it to the barrel of a weapon. Another significant advantage of the silencer according to the invention is that it can also be used for handguns that have a movable barrel or a self-loading function. In particular for handguns with a receding and tilting barrel, the silencer according to the invention has proven to be particularly advantageous. The silencer is not attached to the barrel of the gun, allowing the barrel to move independently of the silencer and without interference from the silencer.

1 shows a first exemplary embodiment of a silencer 10 according to the invention, wherein figure (a) shows the silencer in a side view and figure (b) shows the silencer in a perspective view.

The silencer 10 consists essentially of a silencer housing 10a and an end section 11, the end section 11 being arranged on the side of the silencer housing 10a facing the barrel of the pistol. The end portion 11 is adapted so that the silencer 10 can be attached to the breech (slide) of the pistol. The end section 11 of the silencer 10 is preferably designed in such a way that the silencer can be detachably fastened to the breech block of the weapon.

In 1 configuration shown configured as a profile 17. The inner profile 17a of the profile 17 here has an essentially U-shaped form, with the open side of the inner profile 17a being located on the lower side of the end section 11 . The inner profile 17a can also have shapes other than those in 1 have the shape shown. In a special embodiment of the invention, the inner profile 17a of the end section 11 is designed in such a way that it largely corresponds to the outer profile of the breech block (in particular with the front end section of the breech block) of the pistol. The end section 11 of the silencer 10 can then be placed or pushed onto the breech block of the pistol. Depending on the specific configuration of the inner profile 17a and the outer profile of the closure piece, the silencer can be pushed onto the closure piece from the front, ie along the longitudinal axis of the closure piece. If it is not possible to slide it on along the longitudinal axis of the closure piece, the end section 11 of the silencer 10 can also be pushed onto the front end of the closure piece from above by pushing the closure piece into the opening provided on the lower side of the end section 11.

In one embodiment of the silencer according to the invention, latching means, for example latching pins, can be provided on or in the inner profile 17a, which can be brought into engagement with corresponding latching means on the closure piece, so that the silencer 10 is locked on the closure piece after being pushed onto the closure piece. The latching means are preferably designed in such a way that the locking can be released by manual actuation, for example, and the silencer can be removed from the closure piece. Alternative locking means 18 can be provided, for example magnets which are arranged on or in the side walls of the profile 17 and which interact with the closure piece if the closure piece has appropriate magnetic properties.

In one embodiment, corresponding counter-magnets can also be provided on the closure piece, which interact with the magnets arranged on the end section after the muffler has been pushed onto the closure piece.

In yet another embodiment, the locking means 18 can comprise eccentric levers, for example, which can also be arranged on the two side walls of the profile 17 and with which the silencer can be locked on the locking piece after it has been pushed onto the locking piece. Likewise, locking rockers can be provided on the side walls of the profile 17, with which the silencer is automatically locked when it is pushed onto the closure piece and which can be actuated to release the locking.

It is essential for the present invention that the silencer has a silencer housing 10a and a correspondingly designed end section 11, with which the silencer or the silencer housing 10a can be attached to a breech block of the weapon, so that the silencer can be mounted independently of the weapon barrel together with the breech block is movable.

The end section 11 or the locking means required for locking can be provided to match the respective closure piece. For example, if the closure piece has a circular outer profile, the inner profile 17a of the end section 11 can have a semicircular or circular profile, for example.

the inside 1 silencer shown is designed in one piece or in one piece. This means that the end portion 11 and the muffler housing 10a are essentially made in one piece or are made in two parts and then assembled in such a way that they cannot be separated from one another essentially non-destructively.

The muffler housing 10a here has an essentially L-shaped basic shape, with the interior of the muffler also being designed essentially L-shaped, as for example in FIG 2 , figure (a) shown. Appropriate damping means or damping materials can be provided in the interior of the muffler housing 10a. In addition, aids, laser sights or lighting can also be accommodated in the interior of the silencer.

2 shows the in 1 Silencer 10 shown in a longitudinal section (figure (a)), in a cross section (figure (b)) and in a perspective view (figure (c)). The longitudinal section runs along the longitudinal axis L of the silencer. The cross section runs along the transverse axis Q of the muffler.

Figure (a) shows the end section 11 protruding at the rear of the muffler housing 10a. The firing channel opening 14 provided on the rear housing wall of the silencer housing 10a can also be seen. A firing channel 12 is arranged in the silencer housing 10a, the axis of which corresponds to the axis of the weapon barrel. The firing channel opening 14 is designed in such a way that the front end of the weapon barrel does not collide with the silencer when the silencer is moved.

In one embodiment of the invention, the firing channel opening 14 can be designed in such a way that when the silencer housing or the silencer is moved relative to the weapon barrel, the front end of the barrel can be brought into engagement with the firing channel opening, i.e. the front end of the barrel can enter the firing channel opening 14 protrudes. As a result, the escape of gas between the barrel muzzle and the rear housing wall of the silencer housing 10a can be reduced.

Furthermore, the rear section 13 of the firing channel 12 can also be designed in such a way that it does not come into contact with the weapon barrel when the silencer is moved relative to the weapon barrel. This must be taken into account in particular if the barrel is a rear-tilting barrel. In this case, the radius of the firing channel opening 14 can have a radius that is large enough to allow the raised front end of the barrel to engage the firing channel opening 14 without collision. Such an arrangement is in 2 shown, whereby it can be seen that the radius of the firing channel opening 14 is larger than the radius of the exit opening of the firing channel 12.

A slot-shaped opening can be provided on the upper side wall of the end section 11, in which the front sight of the weapon can be accommodated after the silencer has been placed on the breech block.

In the case of a non-rear-dipping barrel, the firing channel opening 14 can have a radius which essentially corresponds to the outer radius of the front end of the barrel. As a result, on the one hand the barrel can be introduced unhindered into the firing channel opening 14, and on the other hand the gap between the firing channel opening 14 and the barrel after a shot has been fired is minimized, which also reduces gas escaping from this gap. At the same time, the front end of the barrel can be provided as a guide for the silencer 10, which moves backwards after a shot has been fired and which is attached to the breech block, which moves backwards.

3 shows the in 1 shown silencer in the attached state on a pistol 5. The pistol has, in a known manner, a breech block or slide 6 which, after a shot has been fired, is moved backwards relative to the pistol 5, for example to eject the cartridge case, as shown in figure (b). the 3 shown.

The silencer 10 according to the invention is arranged at the front end of the closure piece 6 , the silencer being pushed with its end section 11 onto the front end of the closure piece 6 and fastened/locked to the closure piece 6 . The coupling between the silencer 10 and the breech piece 6 moves the silencer 10 together with the breech piece 6 backwards after a shot has been fired, so that the muzzle area of the barrel protrudes into the firing channel opening 14 . The underside of the rear section of the silencer housing 10 is designed in such a way that it cannot collide with the top of the front end of the grip of the weapon. For example, a corresponding semi-circular recess may be provided on the underside of the rear section of the muffler housing 10a, such as in FIG 2 apparent.

As a locking device 18 with reference to 1 and 2 mentioned locking means are used to attach the silencer 10 to the breech block 6 of the weapon 5.

4 12 shows a further embodiment of a silencer 10 according to the invention with an end section 11 which is adapted to fasten the silencer to the breech 6 of the weapon 5. FIG. In the embodiment shown here, the rear end of the end section 11 has one or more magnets 15a, which correspond to corresponding counter-magnets 15b provided at the front end of the closure piece 6 and interact with them.

figure 5 shows a further embodiment of a silencer 10 according to the invention with an end section 11. In the embodiment shown here, a fastening means 15 is articulated on the end section 11 in such a way that the fastening means 15 can be pivoted about an axis of rotation relative to the end section 11. The fastening means 15 shown here is a driver 15c, which is adapted to the outer profile of the closure piece 6 Has inner profile. After the end section 11 has been slid onto the front end section of the closure piece 6, the driver 15c can be folded down and locked on the closure piece 6, so that the driver 15c is coupled to the closure piece 6 in a fixed but detachable manner. The silencer 10 is moved together with the closure piece 6 via this driver 15c. As a locking means for locking the driver 15c on the closure piece 6 with reference to 1 and 2 mentioned locking means are provided.

6 shows a further embodiment of a silencer 10 according to the invention with an end section 11. Quick-release means are provided on the end section 11, which enable the silencer to be fastened to the closure piece 6. A driver 15c is also provided here as the fastening means 15 and can be fastened to the front end of the closure piece 6 by means of an eccentric lever. Corresponding counterparts of the quick-release means 16 are provided at the front end of the driver 15c in order to fasten the muffler 10 to the driver 15c. At the in 6 shown embodiment, the quick-release means are designed as a dovetail connection. Alternatively, the quick-release fasteners 16 can also be designed as a bayonet fastener. In yet another embodiment, clip connections can also be provided as quick-release fasteners, with which the end section 11 of the silencer 10 can be clipped onto the driver 15c.

A rubber coating can be provided on the inner wall of the driver 15, with which damage to the surface of the closure piece 6 can be largely prevented. The rubber coating also has the advantage that the friction between the inner profile of the driver 15c and the outer profile of the locking piece 6 is effectively increased.

The related to 6 shown embodiment of the silencer according to the invention has the advantage that it can be used for arbitrarily configured closure pieces. For this purpose, only the driver or the fastening means 15 has to be adapted accordingly to the closure piece 6 . If the fastening means 15 can be arranged detachably on the end section 11 of the silencer 10 (as in 6 shown) only the fastener 15 has to be exchanged in order to be able to attach the silencer of another weapon.

The related to 6 The quick-release fasteners 16 shown can also be provided directly on the end section 11 of the silencer and the corresponding counterparts of the quick-release fasteners 16 can be provided on the breech block of the weapon. This means that the silencer can also be attached directly to the locking piece without a driver.
