Mounting Device for Silencer

This application claims priority to German Patent Application Serial No. DE 10 2024 115 542.6, filed Jun. 4, 2024, the entire disclosure of which is hereby incorporated herein by reference in its entirety.

The invention relates to a fastening device for fastening a silencer to a firearm, in particular to a handgun.

Handguns are understood to be sidearms such as recoil loaders, gas-pressure loaders, pistols, or the like.

It is known to arrange a silencer on a firearm, such as a pistol.

shows a silencerknown from the prior art, which is attached to a weapon, wherein only the front end of the weapon is shown here, i.e. only the slide/barrelof the weapon.

Below the slide/barrel, a mounting rail to which the silencer can be attached is provided on the grip of the weapon. For the fastening, a fastening railof the silenceris pushed onto the mounting rail of the weapon. The fastening railis arranged at the rear end, i.e. at the end facing the weapon, of the silencer housing.

This way of fastening has the advantage that the silencercan be attached to the weaponindependently of the barrel/slide. A disadvantage, however, is that when a shot is fired, the silenceris caused to vibrate, in particular if the grip is made of plastic, such as polyamide. The silencer can vibrate in different directions, in particular horizontally (shown by arrow P) and vertically (shown by arrow P). The silencer performs the vibrations independently of the movement of the barrel, so that under certain circumstances the weapon is ready to fire again while the silencer is still vibrating. While the silencer is vibrating, the center axis of the barrel is not coaxial with the center axis of the firing channelformed in the silencer, so that no further shot can be fired as long as the silencer is vibrating. This disadvantage is particularly noticeable with semi-automatic or fully automatic firearms.

It is therefore the task of the present invention to provide solutions which at least partially avoid the above disadvantages known from the prior art and which largely prevent a vibration of a silencer attached to the grip or at least reduce it to such an extent that the firing of one or more shots is not impaired.

This object is achieved according to the invention with a fastening device for fastening a silencer to a handgun according to the independent patent claim. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

Accordingly, a fastening device for fastening a silencer to a handgun is provided, wherein the handgun has a mounting rail and a trigger guard, wherein the fastening device has a fastening rail, wherein the fastening rail is designed

In this context, “below the support surface” means that the axial projection is located at the lower end of the support surface. “Axial projection” means that a projection running in the axial direction is arranged at the lower end of the support surface. The underside of the trigger guard is essentially the portion of the trigger guard that runs largely parallel to the barrel of the weapon.

This prevents the silencer attached to the weapon from vibrating when a shot is fired.

Without an axial projection according to the invention, the silencer can tip downwards when a shot is fired (due to the gas pressure), so that the support surface of the fastening rail may in some circumstances no longer have contact with the end face of the trigger guard. The firing channel of the barrel will then no longer be coaxial with the firing channel of the silencer, which can result in a “glancing shot” in the silencer when a shot is fired. The provision of the axial projection according to the invention and its contact surface prevents the support surface of the fastening rail from losing contact with the end face of the trigger guard. This allows the force to be absorbed by the end face of the trigger guard when a shot is fired, preventing the silencer from tipping downwards.

When one or more shots are fired, the polymer of the handgun grip may expand differently than the metal (e.g. aluminum) of the silencer. Here too, it may happen that the support surface of the fastening rail may in some circumstances no longer have contact with the end face of the trigger guard. The result would again be a tipping of the silencer. The axial projection according to the invention effectively prevents the silencer from tipping/vibrating in this situation as well.

It is advantageous if a first section of the contact surface corresponding to the underside of the trigger guard runs largely parallel to the fastening rail. In this context, “largely parallel” means that the first section of the contact surface can also be slightly inclined or slightly slanted in relation to the fastening rail, i.e. that an angle of a few degrees can be enclosed between the first section of the contact surface and the fastening rail.

It can further be advantageous if a second section of the contact surface corresponding to the transition section of the trigger guard has a predetermined radius which corresponds to an outer radius of the transition section of the trigger guard.

In one embodiment of the invention, a second section of the contact surface corresponding to the transition section of the trigger guard can run obliquely, i.e. at a predetermined angle, to the support surface of the fastening rail.

In an embodiment of the invention with a first section of the contact surface and with a second section of the contact surface, the second section of the contact surface can

In an embodiment of the invention,

It is advantageous if the support surface of the fastening rail lies largely flush on the end-face counter-support surface when the fastening device is attached to the firearm.

At the rear end of the fastening rail, two axial wings spaced apart from one another can be provided, which project at least partially in the axial direction on the support surface.

It is advantageous if the spacing of the two wings from one another is selected such that it substantially corresponds to the width of the front end of the trigger guard, with the result that the front end of the trigger guard substantially form-fittingly engages at least in sections between the two wings when the fastening device is attached to the handgun.

This largely prevents the silencer from vibrating horizontally relative to the weapon.

The support surface can run between the two wings and perpendicular to the two wings.

It is advantageous if two side walls running parallel to each other are arranged on the upper side of the axial projection, wherein the contact surface runs between the two side walls. This can further prevent the silencer from vibrating horizontally relative to the weapon.

The distance between the two side walls can be selected such that it corresponds to the width of the underside of the trigger guard. Alternatively or additionally, the two side walls can be designed as guide rails that correspond to guide means on the underside or on a lower portion of the trigger guard.

The fastening rail and the axial projection can be formed in one piece.

Furthermore, a silencer for a handgun is provided, wherein the silencer has a fastening device according to the invention.

The silencer and the fastening device can be formed in one or two parts.

The fastening device according to the invention described below for fastening a silencer to a handgun has the advantage that the silencer can be attached to the weapon independently of the barrel/slide. Another significant advantage is that a vibration of the silencer, in particular after a shot has been fired, is effectively prevented. A silencer attached to a handgun according to the invention thereby also makes possible semi-automatic or fully automatic operation of the firearm.

shows a fastening device according to the invention for fastening a silencerto a firearm. The firearm shown here is a pistol.

The silencerhere consists of a silencer housingand a fastening railarranged on the rear end wall of the silencer housing. The rear end wall of the silencer housingis the end wall that faces the barrel/slidewhen the silencer is attached to the weapon.

Alternatively, the fastening railcan also be arranged on a lower side wall of the silencer and extend beyond the rear end wall of the silencer.

The fastening railand the silencer can be formed in one piece or in two pieces. The fastening railand the silencer arranged thereon are hereinafter referred to jointly as silencer.

The fastening railhere forms the fastening device according to the invention.

On the underside of the gripof the weapon, a mounting railis provided, onto which the fastening railis pushed (along the arrow shown in). The barrel and the slidecan move independently of the silencer attached to the fastening rail. A detailed view of a possible embodiment of the fastening railaccording to the invention is shown in.

The rear endof the fastening railhas a support surface(shown in), the surface of which largely corresponds to the end-face surfaceof the trigger guard. The end-face surfaceof the trigger guardforms a counter-support surface for the support surfaceof the fastening rail. The support surfaceof the fastening railis described in more detail with reference to,and.

Below the support surface, an axial projectionis arranged or provided, on the upper side of which a contact surface(seen into) is formed. The contact surfacecorresponds at least in sections to an undersideof the trigger guardand/or to a transition sectionbetween the end faceof the trigger guardand the undersideof the trigger guard, in such a way that the contact surfacelies at least in sections flush on the undersideand/or on the transition sectionof the trigger guardwhen the fastening device is attached to the firearm. The projectionprojects beyond the support surfacein the axial direction or extends beyond the support surfacein the axial direction.

The pistol or the grip of the pistol can be made of a polymer. The fastening device according to the invention can be made of a metal, such as aluminum. The thermal expansion of polymer, e.g. when a shot is fired or at high ambient temperatures, is different from the thermal expansion of aluminum. At high temperatures, it can therefore happen that there is no longer any contact between the support surfaceand the end-face surfaceof the trigger guard(counter-support surface), which may result in the silencer vibrating relative to the weapon when a shot is fired (due to the gas pressure), in particular tipping downwards. This in turn has the result that the firing channel of the silencer is no longer coaxial with the barrel of the weapon. This can result in grazing shots in the silencer, which can cause damage to the silencer.

The axial projectionprevents the silencer from tipping downwards. The axial projectionthus causes the support surfaceand the end-face surfaceof the trigger guardto remain in contact. When a shot is fired, the force is then absorbed again by the counter-support surface and tipping downwards is prevented. The specific design of the axial projectionis described in more detail with reference toand.

To attach the silencer to the firearmwith the fastening rail, it is pushed completely onto the mounting railso that the support surfaceof the fastening railrests largely flush on the counter-support surfaceAt the same time, the axial projectionthen also rests on the undersideand/or on the transition sectionof the trigger guard.

The silencer can be locked to the weapon using the locking rockersarranged at the rear endof the fastening rail, so that the silencercannot detach independently or unintentionally from the weapon.

The fact that the support surfaceof the fastening railrests on the counter-support surfaceof the trigger guardwhen the silenceris mounted on the weapon reliably prevents the silencer from vibrating in the vertical direction Pafter a shot has been fired from the weapon. The front portion of the gripcan no longer vibrate downwards because downward movement is prevented by the fastening railresting on the counter-support surfaceof the trigger guard. If the grip and the fastening device are made of different materials, vibration is also prevented by the axial projection—the axial projection ensures that the support surfaceof the fastening railalways rests on the counter-support surfaceof the trigger guard. This also increases the overall rigidity of the grip.

At the rear endof the fastening rail, two axially projecting wingscan also be provided, which run spaced apart from one another and largely parallel to one another. The support surface of the fastening railruns between these two wings. The distance between the two wings is selected so that it essentially corresponds to the width of the end-face section (the section on which the counter-support surfaceis located) of the trigger guard. After the silencer has been pushed completely onto the mounting rail, the two wingsrun laterally along the end-face section of the trigger guard. This means that the end-face section of the trigger guardengages essentially in a form-fitting manner between the two wings. The engagement of the trigger guardbetween the two wingsensures that the silencervibrates in the horizontal direction Pafter a shot has been fired from the weapon. In addition, this further increases the rigidity of the grip.

On the upper side of the axial projection, two side wallsrunning parallel to one another can be arranged (as can be seen in), wherein the contact surfaceruns between the two side walls. This further prevents the silencer from vibrating in the horizontal direction P.

The above-mentioned measures improve the vibration behavior of the silencer to such an extent that semi-automatic or fully automatic operation of the firearm is also possible, in particular under thermally suboptimal conditions. These measures almost completely prevent the silencer from vibrating after a shot has been fired.

In the embodiment shown in, the counter-support surfacehas a substantially concave surface. Accordingly, the corresponding support surfaceof the fastening railhas a convex surface. Of course, it is also possible for the counter-support surfaceto have a substantially convex surface and for the support surface to have a concave surface corresponding substantially thereto.

In principle, the surfaces of the support surface and the counter-support surface can be designed as desired. However, it is important according to the invention that the two surfaces correspond to each other so that when the silencer is mounted, the support surface of the fastening railrests on the counter-support surface, preferably largely flush with its shape.

The fastening railof the fastening device has two upper side walls. The two side wallseach have internal longitudinal guideswhich are designed as guide grooves. The guide grooves correspond to the mounting rail, which is provided on the weapon on the gripbelow the barrel/slide. With the help of the longitudinal guides, the silencer can be pushed onto the mounting railof the firearm.
