DETAILED DESCRIPTION

[0045] The silencer according to the invention that is described in the following has the advantage that it can be fastened to or mounted on and dismounted from the gun barrel of a gun particularly easily and rapidly, in particular without being screwed thereto. Another significant advantage of the silencer according to the invention is that it can also be used for portable firearms which have a movable barrel or a self-loading function. The silencer according to the invention has proved to be particularly advantageous in particular for portable firearms comprising a recoiling and tilting barrel. The silencer is not fastened to the barrel of the gun, and therefore the barrel can be moved independently of the silencer and without being impaired by the silencer.

[0046] FIGS. 1A-B show a first embodiment of a silencer 10 according to the invention, with FIG. 1A showing the silencer in a side view and FIG. 1B showing the silencer in a perspective view.

[0047] The silencer 10 substantially consists of a silencer housing 10a and an end portion 11, with the end portion 11 being arranged on the side of the silencer housing 10a facing the gun barrel of the pistol. The end portion 11 is adapted such that the silencer 10 can be fastened to the breechblock (slide) of the pistol. The end portion 11 of the silencer 10 is preferably designed such that the silencer can be detachably fastened to the breechblock of the gun.

[0048] In the embodiment shown in FIGS. 1A-B, the rear axially projecting end portion 11, with rear meaning on the side of the silencer housing 10a facing the gun barrel of the pistol, is designed as a profile 17. The inner profile 17a of the profile 17 is substantially U-shaped here, with the open side of the inner profile 17a being located on the lower side of the end portion 11. The inner profile 17a may also have other shapes than the shape shown in FIGS. 1A-B. In a particular embodiment of the invention, the inner profile 17a of the end portion 11 is designed such that it largely corresponds to the outer profile of the breechblock (in particular to the front end portion of the breechblock) of the pistol. The end portion 11 of the silencer 10 can then be placed or slid onto the breechblock of the pistol. Depending on the specific design of the inner profile 17a and the outer profile of the breechblock, the silencer may be slid onto the breechblock from the front, i.e. along the longitudinal axis of the breechblock. If it is not possible to slide said silencer along the longitudinal axis of the breechblock in this way, the end portion 11 of the silencer 10 can also be slid onto the front end of the breechblock from above, by the breechblock being inserted into the opening provided on the lower side of the end portion 11.

[0049] In an embodiment of the silencer according to the invention, latching means, for example latching pins, may be provided on or in the inner profile 17a, and can be brought into engagement with corresponding latching means on the breechblock such that the silencer 10 is locked to the breechblock after being slid onto the breechblock. The latching means are preferably designed such that the locking can be released by manual actuation, for example, and the silencer can be removed from the breechblock. Alternative locking means 18 may be provided, for example magnets, which are arranged on or in the side walls of the profile 17 and interact with the breechblock, provided that the breechblock has corresponding magnetic properties.

[0050] In an embodiment, corresponding counter-magnets may also be provided on the breechblock, which interact with the magnets arranged on the end portion after the silencer has been slid onto the breechblock.

[0051] In yet another embodiment, the locking means 18 may for example comprise eccentric levers, which may likewise be arranged on the two side walls of the profile 17 and by means of which the silencer can be locked to the breechblock after being slid onto the breechblock. Likewise, locking rockers may be provided on the side walls of the profile 17, by means of which the silencer is automatically locked when slid onto the breechblock and which can be actuated to release the locking.

[0052] It is essential to the present invention for the silencer to comprise a silencer housing 10a and a correspondingly designed end portion 11, by means of which the silencer or silencer housing 10a can be fastened to the breechblock of the gun such that the silencer can be moved together with the breechblock independently of the gun barrel.

[0053] The end portion 11 or the locking means required for the locking can be designed to fit the relevant breechblock. If, for example, the breechblock has a circular outer profile, the inner profile 17a of the end portion 11 may have a semicircular or circular profile, for example.

[0054] The silencer shown in FIGS. 1A-B is formed in one piece/integrally. This means that the end portion 11 and the silencer housing 10a are substantially manufactured from one piece or are manufactured from two parts and are then joined together such that they substantially cannot be separated from one another in a non-destructive manner.

[0055] The silencer housing 10a has a substantially L-shaped basic shape here, with the interior of the silencer being substantially L-shaped, as shown in FIG. 2A. Corresponding silencing means or silencing materials may be provided in the interior of the silencer housing 10a. In addition, auxiliary means, laser sights or lighting means may also be received in the interior of the silencer.

[0056] FIGS. 2A-C show a longitudinal section (FIG. 2A), a cross section (FIG. 2B) and a perspective view (FIG. 2C) of the silencer 10 shown in FIGS. 1A-B. The longitudinal section extends along the longitudinal axis L of the silencer. The cross section extends along the transverse axis Q of the silencer.

[0057] In FIG. 2A, the end portion 11, which projects on the rear side of the silencer housing 10a, can be seen. The barrel-channel opening 14 provided on the rear housing wall of the silencer housing 10a can also be seen. A barrel channel 12 is arranged in the silencer housing 10a, the axis of which channel corresponds to the axis of the gun barrel. The barrel-channel opening 14 is designed such that the front end of the gun barrel does not collide with the silencer when the silencer moves.

[0058] In an embodiment of the invention, the barrel-channel opening 14 may be designed such that, when the silencer housing or the silencer moves relative to the gun barrel, the front end of the barrel can be brought into engagement with the barrel-channel opening, i.e. such that the front end of the barrel protrudes into the barrel-channel opening 14. As a result, the escape of gas between the muzzle and the rear housing wall of the silencer housing 10a can be reduced.

[0059] Furthermore, the rear portion 13 of the barrel channel 12 may also be designed such that it does not come into contact with the gun barrel when the silencer moves relative to the gun barrel. This must be borne in mind in particular if the barrel is a barrel that tilts backward. In this case, the radius of the barrel-channel opening 14 may be large enough that the raised front end of the barrel can be brought into engagement with the barrel-channel opening 14 without any collisions. Such a configuration is shown in FIGS. 2A-C, from which it can be seen that the radius of the barrel-channel opening 14 is larger than the radius of the outlet opening of the barrel channel 12.

[0060] A slot-shaped opening may be provided on the upper side wall of the end portion 11, in which opening the front sight of the gun is positioned after the silencer is placed onto the breechblock.

[0061] For a barrel that does not tilt backward, the barrel-channel opening 14 may have a radius which substantially corresponds to the outer radius of the front end of the barrel. As a result, on one hand the barrel can be introduced into the barrel-channel opening 14 unimpeded, and on the other hand the gap between the barrel-channel opening 14 and the barrel is minimized after a shot has been fired, meaning that the escape of gases from this gap is also reduced. At the same time, the front end of the barrel may be provided as a guide for the silencer 10, which recoils after a shot is fired, and this silencer is indeed fastened to the recoiling breechblock.

[0062] FIGS. 3A-B show the silencer shown in FIGS. 1A-B when fastened to a pistol 5. The pistol comprises, in a known manner, a breechblock or a slide 6, which is moved backward relative to the pistol 5 after a shot is fired, for example to eject the shell casing, as shown in FIG. 3B.

[0063] The silencer 10 according to the invention is arranged at the front end of the breechblock 6, with the silencer having been slid onto the front end of the breechblock 6 by its end portion 11 and fastened/locked to the breechblock 6. By means of the coupling between the silencer 10 and the breechblock 6, the silencer 10 is moved backward together with the breechblock 6 after a shot is fired such that the muzzle region of the barrel protrudes into the barrel-channel opening 14. The lower face of the rear portion of the silencer housing 10 is designed such that it can no longer collide with the upper face of the front end of the handle part of the gun. For example, a corresponding semicircular cut-out may be provided on the lower face of the rear portion of the silencer housing 10a, as can be seen in FIGS. 2A-C.

[0064] The locking means mentioned with reference to FIGS. 1A-B and 2A-C may be used as the locking means 18 in order to fasten the silencer 10 to the breechblock 6 of the gun 5.

[0065] FIG. 4 shows another embodiment of a silencer 10 according to the invention comprising an end portion 11 that is adapted to fasten the silencer to the breechblock 6 of the gun 5. In the embodiment shown here, the rear end of the end portion 11 comprises one or more magnets 15a which correspond to and interact with corresponding counter-magnets 15b provided on the front end of the breechblock 6.

[0066] FIG. 5 shows another embodiment of a silencer 10 according to the invention comprising an end portion 11. In the embodiment shown here, a fastening means 15 is articulated to the end portion 11, and specifically such that the fastening means 15 can be pivoted about a rotational axis relative to the end portion 11. The fastening means 15 shown here is a catch 15c which has an inner profile that is adapted to the outer profile of the breechblock 6. After sliding the end portion 11 onto the front end portion of the breechblock 6, the catch 15c can be tilted downwards and locked to the breechblock 6 such that the catch 15c is rigidly but detachably coupled to the breechblock 6. The silencer 10 is moved together with the breechblock 6 by means of this catch 15c. The locking means mentioned with reference to FIGS. 1A-B and 2A-C may be provided as the locking means for locking the catch 15c to the breechblock 6.

[0067] FIG. 6 shows another embodiment of a silencer 10 according to the invention comprising an end portion 11. Quick-release means which make it possible to fasten the silencer to the breechblock 6 are provided on the end portion 11. A catch 15c which can be fastened to the front end of the breechblock 6 by means of an eccentric lever is likewise provided here as a fastening means 15. Corresponding counterparts of the quick-release means 16 are provided on the front end of the catch 15c in order to fasten the silencer 10 to the catch 15c. In the embodiment shown in FIG. 6, the quick-release means are designed as a dovetail joint. Alternatively, the quick-release means 16 may also be designed as a bayonet catch. In yet another embodiment, clip connections may also be provided as quick-release means, by means of which the end portion 11 of the silencer 10 can be clipped to the catch 15c.

[0068] A rubber coating may be provided on the inner wall of the catch 15, by means of which damage to the surface of the breechblock 6 can be largely prevented. The rubber coating also has the advantage that the friction between the inner profile of the catch 15c and the outer profile of the breechblock 6 is effectively increased.

[0069] The embodiment of the silencer according to the invention shown with reference to FIG. 6 has the advantage that this can be used for breechblocks of any design. To do this, the catch or fastening means 15 merely has to be adapted to the breechblock 6 accordingly. Provided that the fastening means 15 can be detachably arranged on the end portion 11 of the silencer 10 (as shown in FIG. 6), only the fastening means 15 needs to be replaced to make it possible to fasten the silencer of a different gun.

[0070] The quick-release means 16 shown in FIG. 6 may also be directly provided on the end portion 11 of the silencer and the corresponding counterparts of the quick-release means 16 may be provided on the breechblock of the gun. Therefore, the silencer can be directly fastened to the breechblock even without a catch.
