Description

Subject matter of the invention

[0001] The invention relates to a fastening device for attaching a silencer to a firearm, in particular a handgun. Background of the invention

[0002] Handguns are understood to be hand-held firearms, such as recoil-operated weapons, gas-operated weapons, pistols, or the like.

[0003] It is known to attach a silencer to a firearm, for example a pistol.

[0004] Fig. 1 shows a silencer 10 known from the prior art, which is attached to a weapon 90, whereby only the front end of the weapon is shown here, i.e. only the breech / barrel 91 of the weapon 90.

[0005] Below the breech / barrel 91, a mounting rail is provided on the grip of the weapon, to which the silencer can be attached. For attachment, a mounting rail 30 of the silencer 10 is slid onto the mounting rail of the weapon. The mounting rail 30 is located at the rear end, i.e., at the end facing the weapon, of the silencer housing 11.

[0006] This type of attachment has the advantage that the silencer 10 can be attached to the weapon 90 independently of the barrel / breech. However, a disadvantage is that when a shot is fired, the silencer 10 is set into vibration, especially if the grip is made of plastic, such as polyamide. The silencer can vibrate in different directions, particularly horizontally (shown by arrow P1) and vertically (shown by arrow P2). The silencer vibrates independently of the barrel's movement, so the weapon may be ready to fire again while the silencer is still vibrating. While the silencer is vibrating, the barrel's central axis is not coaxial with the central axis of the firing channel 20 formed in the silencer, so 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. Object of the invention

[0007] The object of the present invention is therefore to provide solutions that at least partially avoid the aforementioned disadvantages known from the prior art and that largely prevent or at least reduce the vibration of a silencer attached to the handle so as not to impair the firing of one or more shots. Inventive solution

[0008] This problem is solved according to the invention by a fastening device for attaching a silencer to a handgun according to the independent claim. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

[0009] Accordingly, a mounting device for attaching a silencer to a handgun is provided, wherein the handgun has a mounting rail and a trigger guard, wherein the mounting device has a mounting rail, wherein the mounting rail is designed to be brought into contact with the mounting rail of the handgun or to be slid onto the mounting rail of the handgun, wherein the mounting rail has a support surface which rests at least partially on an end face of the trigger guard of the handgun when the mounting device is attached to the handgun, and wherein a projection is arranged below the support surface, the projection having a bearing surface, the bearing surface corresponding at least partially with an underside of the trigger guard and / or with a transition section between the end face of the trigger guard and the underside of the trigger guard, such that the bearing surface rests at least partially flush with the underside of the trigger guard and / or with the transition section of the trigger guard when the mounting device is attached to the handgun.

[0010] "Below the support surface" in this context means that the axial projection is located at the lower end of the support surface. "Axial projection" means that an axially extending projection is located at the lower end of the support surface. The underside of the trigger guard is essentially that section of the trigger guard that runs largely parallel to the barrel of the weapon.

[0011] This prevents the silencer attached to the weapon from oscillating when a shot is fired.

[0012] Without an axial projection according to the invention, the silencer can tilt downwards when a shot is fired (due to gas pressure), so that the support surface of the mounting rail may lose contact with the face of the trigger guard. The barrel's firing channel then no longer runs coaxially with the silencer's firing channel, which can result in a "glancing blow" within the silencer when a shot is fired. The provision of the axial projection according to the invention and its contact surface prevents the mounting rail's support surface from losing contact with the face of the trigger guard. The force is thus absorbed by the face of the trigger guard when a shot is fired, preventing the silencer from tilting downwards.

[0013] When one or more shots are fired, the polymer of the handgun's grip can expand differently than the metal (e.g., aluminum) of the silencer. In this situation, the support surface of the mounting rail may lose contact with the front face of the trigger guard. This would again cause the silencer to tilt. The axial projection according to the invention effectively prevents the silencer from tilting or oscillating in this situation as well.

[0014] It is advantageous if the first section of the contact surface, corresponding to the underside of the trigger guard, runs largely parallel to the mounting rail. "Largely parallel" in this context means that the first section of the contact surface can also be slightly inclined or angled relative to the mounting rail, i.e., that an angle of a few degrees can be formed between the first section of the contact surface and the mounting rail.

[0015] It can also be advantageous if a second section of the contact surface corresponding to the transition section of the trigger guard has a predetermined radius that corresponds to an outer radius of the transition section of the trigger guard.

[0016] 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 mounting rail.

[0017] 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 oblique to the support surface of the mounting rail and oblique to the first section of the contact surface, or have the predetermined radius.

[0018] In one embodiment of the invention The surface of the support facing the trigger guard has a convex curvature, and the front end of the trigger guard can be designed as a counter-support surface on the front face, which corresponds at least partially to the convexly curved support surface.

[0019] It is advantageous if the support surface of the mounting rail rests largely flush with the front-facing counter-support surface when the mounting device is attached to the firearm.

[0020] At the rear end of the mounting rail, two axial wings spaced apart from each other can be provided, which project at least partially in the axial direction from the support surface.

[0021] It is advantageous if the distance between the two wings is chosen so that it essentially corresponds to the width of the front end of the trigger guard, so that the front end of the trigger guard engages, at least partially, in a substantially form-fitting manner between the two wings when the fastening device is attached to the firearm.

[0022] This largely prevents the silencer from oscillating horizontally relative to the weapon.

[0023] The support surface can run between the two wings and perpendicular to the two wings.

[0024] It is advantageous if two parallel side walls are arranged on the upper side of the axial projection, with the contact surface located between the two side walls. This further prevents horizontal oscillation of the silencer relative to the weapon.

[0025] The distance between the two side walls can be chosen to correspond 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 elements on the underside or on a lower section of the trigger guard.

[0026] The mounting rail and the axial projection can be designed as a single piece.

[0027] Furthermore, a silencer for a handgun is provided, wherein the silencer has a fastening device according to the invention.

[0028] The silencer and the mounting device can be designed as a single piece or in two parts. Brief description of the characters

[0029] Details and features of the invention, as well as specific embodiments of the invention, will become apparent from the following description in conjunction with the drawing. The drawing shows: Fig. 1 a silencer known from the prior art, attached to a weapon; Fig. 2 a fastening device according to the invention for attaching a silencer to a handgun; Fig. 3 the rear end of a fastening device according to the invention in a perspective view; Fig. 4 a sectional view of the Fig. 3 The rear end of a fastening device according to the invention is shown; Fig. 5 shows a silencer according to the invention; and Fig. 6 shows various embodiments of the fastening device according to the invention and various embodiments of a trigger guard of a handgun. Detailed description of the invention

[0030] The mounting device described below, according to the invention, for attaching a silencer to a handgun has the advantage that the silencer can be attached to the weapon independently of the barrel / breech. A further significant advantage is that it effectively prevents the silencer from oscillating, particularly after a shot has been fired. A silencer attached to a handgun according to the invention thus also enables semi-automatic or fully automatic operation of the firearm.

[0031] Fig. 2 Figure 1 shows a fastening device according to the invention for attaching a silencer 10 to a firearm 90. The firearm shown here is a pistol.

[0032] The silencer 10 consists of a silencer housing 11 and a mounting rail 30 arranged on the rear end wall of the silencer housing 11. The rear end wall of the silencer housing 11 is the end wall that faces the barrel / breech 91 when the silencer is attached to the weapon 90.

[0033] The mounting rail 30 can alternatively be arranged on a lower side wall of the silencer and extend beyond the rear end wall of the silencer.

[0034] The mounting rail 30 and the silencer can be designed as a single piece or in two parts. The mounting rail 30 and the silencer attached to it are hereinafter collectively referred to as silencer 10.

[0035] The mounting rail 30 forms the mounting device according to the invention.

[0036] A mounting rail 94 is provided on the underside of the grip 92 of the weapon 90, onto which the fastening rail 30 is slid (along the in Fig. 2 (arrow shown). The barrel and the breechblock 91 can move independently of the silencer attached to the mounting rail 30. A detailed view of a possible embodiment of the mounting rail 30 according to the invention is shown in Fig. 5 shown.

[0037] The rear end 33 of the mounting rail 30 has a support surface 36 (shown in Fig. 3 ) whose surface largely corresponds to the end-face surface 97a of the trigger guard 97. The end-face surface 97a of the trigger guard 97 here forms a counter-support surface for the support surface 36 of the mounting rail 30. The support surface 36 of the mounting rail 30 is oriented with reference to Fig. 3, Fig. 4 and Fig.5 described in more detail.

[0038] Below the support surface 36, an axial projection 70 is arranged or provided, on the upper side of which a bearing surface 71 (as seen in Fig. 3 bis Fig. 6 The contact surface 71 corresponds at least partially to an underside 97c of the trigger guard 97 and / or to a transition section 97b between the end face 97a of the trigger guard 97 and the underside 97c of the trigger guard 97, such that the contact surface 71 rests flush with the underside 97c and / or the transition section 97b of the trigger guard 97, at least partially, when the mounting device is attached to the firearm. The projection 70 extends axially beyond the support surface 36.

[0039] The pistol or the pistol grip 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, differs from the thermal expansion of aluminum. At high temperatures, it can therefore happen that there is no longer any contact between the support surface 36 and the end face 97a of the trigger guard 97 (counter-support surface), which can result in the silencer vibrating relative to the weapon when a shot is fired (due to the gas pressure), and in particular tilting downwards. This, in turn, means that the firing channel of the silencer is no longer coaxial with the barrel of the weapon. Grazing shots in the silencer can result, which can lead to damage to the silencer.

[0040] The axial projection 70 prevents the silencer from tipping downwards. The axial projection 70 ensures that the support surface 36 and the end face 97a of the trigger guard 97 remain in contact. When a shot is fired, the force is then absorbed by the opposing support surface, preventing downward tipping. The specific design of the axial projection 70 is described with reference to Fig. 3 and Fig. 6 described in more detail.

[0041] To attach the silencer to the firearm 90, the mounting rail 30 is fully slid onto the mounting rail 94, so that the support surface 36 of the mounting rail 30 rests almost flush with the counter-support surface 97a. At the same time, the axial projection 70 also rests on the underside 97c and / or on the transition section 97b of the trigger guard 97.

[0042] The locking rockers 13 arranged at the rear end 33 of the mounting rail 30 allow the silencer to be locked to the weapon so that the silencer 10 cannot detach itself from the weapon or unintentionally.

[0043] Because the support surface 36 of the mounting rail 30 rests on the counter-support surface 97a of the trigger guard 97 when a silencer 10 is mounted on the weapon, the silencer is reliably prevented from oscillating vertically P2 after a shot has been fired. The front section of the grip 92 can no longer oscillate downwards because downward movement is prevented by the mounting rail 30 resting on the counter-support surface 97a of the trigger guard 97. With different materials used for the grip and the mounting device, oscillation is further prevented by the axial projection 70 – the axial projection ensures that the support surface 36 of the mounting rail 30 always rests on the counter-support surface 97a of the trigger guard 97. This also increases the overall rigidity of the grip 92.

[0044] At the rear end 33 of the mounting rail 30, two axially projecting wings 35 can also be provided, spaced apart from each other and running largely parallel to each other. The support surface of the mounting rail 30 runs between these two wings 35. The distance between the two wings is chosen such that it essentially corresponds to the width of the front section (the section on which the counter-support surface 97a is located) of the trigger guard 97. After the silencer has been completely slid onto the mounting rail 94, the two wings 35 extend laterally along the front section of the trigger guard 97. This means that the front section of the trigger guard 97 engages essentially positively between the two wings 35. The engagement of the trigger guard 97 between the two wings 35 ensures that the silencer 10 oscillates in the horizontal direction P1 after a shot has been fired from the weapon.Furthermore, this further increases the stiffness of the handle.

[0045] Two parallel side walls 72 can be arranged on the upper side of the axial projection 70 (as in Fig. 3 (as can be seen), with the contact surface 71 running between the two side walls 72. This further prevents the silencer from oscillating in the horizontal direction P1.

[0046] The aforementioned measures improve the silencer's vibration behavior to such an extent that semi-automatic or fully automatic operation of the firearm is possible, particularly even under less than ideal thermal conditions. This is because these measures almost completely prevent the silencer from vibrating after a shot is fired.

[0047] At the in Fig. 2 In the embodiment shown, the counter-support surface 97a has a substantially concave surface. Accordingly, the corresponding support surface 36 of the mounting rail 30 has a convex surface. Of course, it is also possible that the counter-support surface 97a has a substantially convex surface and the support surface has a substantially corresponding concave surface.

[0048] In principle, the surfaces of the support surface and the counter-support surface can be designed as desired. However, according to the invention, it is important that the two surfaces correspond to each other so that, when the silencer is mounted, the support surface of the mounting rail 30 rests on the counter-support surface, preferably largely flush.

[0049] Fig. 3 Figure 1 shows the rear end 33 of a fastening device according to the invention in a perspective view.

[0050] The mounting rail 30 of the mounting device has two upper side walls 31. Each of the two side walls 31 has internal longitudinal guides 32, which are designed as guide grooves. The guide grooves correspond to the mounting rail 94, which is provided on the grip 92 below the barrel / breech 91 of the firearm. The silencer can be slid onto the mounting rail 94 of the firearm with the aid of the longitudinal guides 32.

[0051] At the rear end 33, a support surface 36 is formed, which is essentially perpendicular to the longitudinal axis LA of the mounting rail 30. Furthermore, the support surface 36 extends between two wings 35 formed at the rear end, the wings 35 being arranged essentially perpendicular to the support surface 36 and running parallel to the longitudinal axis LA of the mounting rail. The two wings 35 project rearward from the support surface 36.

[0052] The support surface 36 itself has a convex surface and is designed to correspond with a concave surface of the end-face counter-support surface 97a of the trigger guard 97 and, when the silencer is mounted, rests essentially flush against it. The support surface 36 can also be flat, i.e., not curved.

[0053] The distance between the two wings 35 is chosen such that it essentially corresponds to the width of the front end of the trigger guard 97. When the silencer is mounted, the front end of the trigger guard 97 engages between the two wings 35, preferably forming a positive fit between the wings and the front end of the trigger guard 97, i.e., that the rear end 33 of the mounting rail 30 cannot move horizontally relative to the trigger guard 97.

[0054] The two side walls 31 with their longitudinal guides 32 do not extend to the two wings 35 or to the support surface 36, because the mounting rail usually ends in front of the trigger bar 97.

[0055] Below the support surface 36, or at the lower end of the support surface 36, an axial projection 70 is arranged, on the upper side of which a contact surface 71 is formed. The axial projection runs essentially parallel to the longitudinal axis LA of the mounting rail. The contact surface 71 corresponds at least partially to a lower surface 97c of the trigger guard 97, such that the contact surface 71 rests flush with the lower surface 97c of the trigger guard 97, at least partially, when the mounting device is attached to the firearm. Further embodiments of the contact surface 71 according to the invention are described with reference to Fig. 6 shown.

[0056] On the upper side of the axial projection 70, two parallel side walls 72 are arranged, with the contact surface 71 extending between the two side walls 72. The side walls 72 are optional.

[0057] If the two side walls are provided, then the distance between the two side walls 72 is chosen to correspond to the width of the underside 97c of the trigger guard 97. Additionally, the two side walls 72 can be designed as guide rails (in Fig. 3 (not shown), which correspond to guide means on the underside 97c of the trigger guard 97.

[0058] Fig. 4 Figure 1 shows the rear end 33 of a fastening device according to the invention in a perspective view and in a sectional view.

[0059] The convex surface of the support surface 36 is clearly visible here. Moreover, this corresponds to the Fig. 4 The rear end 33 of the fastening device shown in the Fig. 3 The rear end 33 shown. The axial projection 70 adjoining the support surface 36, which extends in an axial direction at the lower end of the support surface, is also clearly visible here.

[0060] Fig. 5 Figure 1 shows a specific example of a silencer 10 according to the invention with a mounting device according to the invention. The silencer or silencer housing 11 and the mounting rail 30 are designed as a single unit. In an alternative embodiment, the silencer and the mounting rail 30 can be designed as two parts, i.e., the silencer or silencer housing 11 can be detachably connected to the mounting rail 30.

[0061] On the upper side of the mounting rail 30, two mounting rails 31 are provided, which run essentially parallel to each other and are intended for attaching the silencer to the mounting rail of the firearm. The two mounting rails 31 are designed to correspond with an outer profile of a mounting rail 94 of the firearm.

[0062] The mounting rail 30 can have a locking device designed as a locking pin 12, with which the silencer pushed onto the mounting rail of the weapon can be locked to the weapon in order to prevent unintentional or independent detachment of the silencer from the weapon.

[0063] At the rear end 33 of the mounting rail 30, two vertically extending wings 35 are arranged parallel and spaced apart from each other and parallel to the longitudinal axis LA, projecting axially beyond the rear end 33 of the mounting rail 30. The distance between the two wings 35 corresponds to the width of a front section of a trigger guard 97 of the weapon to which the silencer is attached. Furthermore, the two wings 35 are arranged relative to each other such that, when the silencer is mounted on the weapon, the front section of the trigger guard 97 engages between the two wings.

[0064] When the silencer is attached to the firearm, the front end or front section of the trigger guard 97 engages between the two wings 35, so that the side walls of the trigger guard are essentially flush with the two inner sides of the wings 95.

[0065] At the in Fig. 5 In the embodiment shown, the support surface 36 running between the two wings 35 has a largely flat, rather than a convex, surface. The opposing support surface 97a of the trigger guard 97 is designed accordingly.

[0066] Here too, an axial projection 70 is arranged at the lower end of the support surface 36, which protrudes in the axial direction (largely parallel to the longitudinal axis LA of the fastening device) on the support surface 36.

[0067] On the underside of the mounting rail 30, a further mounting rail 34 is provided, on which additional accessories can be arranged.

[0068] Fig. 6 shows various embodiments of the fastening device according to the invention and various embodiments of a trigger guard of a handgun.

[0069] In the figures (a), (b), (c) and (d) of the Fig. 6 Possible embodiments of the fastening device according to the invention are shown (in section). Figures (e), (f) and (g) of the Fig. 6 Possible designs of a trigger guard 97 of a handgun are shown.

[0070] Figure (e) shows a trigger guard 97 which essentially has a vertical section 97a (counter-support surface) and an adjoining horizontal section 97c.

[0071] Figure (f) shows a trigger guard 97 which essentially has a vertical section 97a (counter-support surface), a horizontal section 97c, and an inclined section 97b extending between the vertical and horizontal sections. The inclined section 97b is at a specific angle to the vertical and horizontal sections of the trigger guard 97.

[0072] Figure (g) shows a trigger guard 97 which essentially has a vertical section 97a (counter-support surface), a horizontal section 97c and a curved section 97b extending between the vertical and the horizontal sections. The curved section 97b has a specific outer radius.

[0073] As shown in Figure (a), the contact surface 71 of the axial projection 70 has a first section 71c that runs largely parallel to the mounting rail 30 and corresponds to the underside 97c of the trigger guard 97, so that the first section 71c rests flush with the underside 97c of the trigger guard 97 when the silencer is mounted on the handgun. A silencer with a mounting device according to Figure (a) can be attached to the handguns according to Figures (e), (f) and (g) – the first section 71c rests in each case on the underside 97c of the trigger guard 97.

[0074] The contact surface 71 of the axial projection 70 according to Figure (b) has a second section 71b which is at a specific angle (e.g., between 60° and 30°) to the support surface 36. The second section 71b corresponds to an inclined section 97b of the trigger guard 97, such that, when the silencer is mounted on the handgun, the second section 71b rests flush against the inclined section 97b of the trigger guard 97. A silencer with a mounting device according to Figure (b) can be attached to the handguns according to Figure (f).

[0075] Figure (c) shows a contact surface 71 of an axial projection 70, which has a first section 71c that runs largely parallel to the mounting rail 30 and corresponds to the underside 97c of the trigger guard 97. Furthermore, the contact surface 71 has a curved second section 71b that extends between the first section 71c and the vertical support surface 36. When the silencer is mounted on the handgun, the first section 71c rests flush against the underside 97c of the trigger guard 97, and the curved second section 71b rests against the curved section 97b of the trigger guard 97. A silencer with a mounting device according to Figure (c) can be attached to the handguns according to Figure (g).It is also possible to attach it to the handguns as shown in the figure (f), although in this case the curved second section 71b does not rest on the slanted section 97b of the trigger guard - but the effect described above is still achieved, since the first section 71c rests flush with the underside 97c of the trigger guard 97.

[0076] The design according to Figure (d) largely corresponds to the design according to Figure (c). In contrast to Figure (c), the design according to Figure (d) does not have a curved, but rather an inclined second section 71b, which, when the silencer is mounted on the handgun, rests against the inclined section 97b of the trigger guard 97. A silencer with a mounting device according to Figure (d) can be attached to the handguns according to Figure (f). Reference symbol:
