DETAILED DESCRIPTION OF THE INVENTION

[0046] The silencer according to the invention described below has, on the one hand, the substantial advantage that it can be attached or mounted and dismantled particularly easily, safely and quickly, in particular without screwing on the firearm. On the other hand, the silencer according to the invention has the advantage that it can also be used for portable firearms that have a moving barrel or a self-loading function without having to use a pulse generator for this purpose, wherein the self-loading function of the portable firearm is nevertheless maintained.

[0047] However, the silencer according to the invention has proven to be particularly advantageous in the simple and safe handling during maintenance of the silencer insert. This is because only the silencer housing has to be removed in order to clean the silencer insert, for example.

[0048] However, the one-part or one-piece design of the attachment rail and of the silencer insert is particularly advantageous of the silencer according to the invention. By attaching the attachment rail to the mounting rail (e.g., Picatinny rail) of the portable firearm, a rigid connection is established between the attachment rail and the mounting rail of the portable firearm. Thus, ultimately, the silencer insert is also rigidly connected to the mounting rail of the portable firearm, so that the silencer insert cannot move relative to the portable firearm, which has the advantage that the shot channel formed in the silencer insert always extends coaxially with the firearm barrel when a shot is fired. In conventional silencers, in which the silencer insert is removed from the silencer housing for maintenance, it is not possible to ensure that the silencer insert still sits stably in the silencer housing even after several shots, i.e., it can occur that after only a few shots, the silencer insert is already arranged in the silencer housing with play (for example, due to different thermal expansions of the silencer insert and the silencer housing), so that it can no longer be ensured that the shot channel formed in the silencer insert extends coaxially with the firearm barrel when a shot is fired.

[0049] Within the meaning of the present invention, “one-part” or “one-piece” means that the silencer insert 50 and the attachment rail 30 form an integral unit and cannot be detached from one another in a non-destructive manner. The silencer insert 50 and the attachment rail 30 may be produced, for example milled, from a single piece of aluminum (or another material suitable for a silencer insert), for example. In one embodiment of the invention, it can be provided that the silencer insert 50 and the attachment rail 30 are produced by means of a 3D printing method, for example from a plastic or from a metal. “One-part” or “one-piece” also means that the silencer insert 50 and the attachment rail 30 may be produced separately from one another and are then assembled such that they cannot be separated from one another in a non-destructive manner.

[0050] FIG. 1 shows a silencer 10 according to the invention in a sectional view along a longitudinal axis of the silencer 10.

[0051] In the embodiment shown here, the silencer 10 comprises a silencer housing 11, a silencer insert 50 and an attachment rail 30. According to the invention, the silencer insert 50 and the attachment rail 30 are designed in one part or in one piece.

[0052] The silencer housing 11 here has a rear end wall HE, which in the mounted state faces the firearm barrel 91 of the portable firearm 90, and a front end wall VE opposite the rear end wall. A U-shaped profile of the silencer housing 11 extends between the rear end wall and the front end wall, as shown in section A-A. Within the meaning of the present invention, U-shaped profiles are also understood to mean profiles that have two largely parallel side walls, wherein the two side walls are connected to one another via a semicircular profile. Important in the sense of the present invention is only that the profile of the silencer housing 11 extending between the front and the rear end wall is designed such that the silencer housing 11 can be pushed onto the silencer insert 50 or placed onto the silencer insert 50.

[0053] According to the embodiment shown in FIG. 1, the silencer housing 11, which has a profile according to section A-A, is pushed along the arrow from above onto the silencer insert 50.

[0054] According to one embodiment of the invention, however, it is also possible for the silencer housing 11 to have only a front end wall VE but no rear end wall HE. In this case, the silencer housing 11 can be pushed either from above (as shown in FIG. 1) or from the front onto the silencer insert 50. In this case, the silencer insert 50 is closed in a gas-tight and pressure-tight manner on its rear side (on the side facing the firearm barrel 91) and has there only one opening that corresponds to the shot channel 20 of the silencer insert 50.

[0055] In a further embodiment according to the invention, it is also possible for the silencer housing 11 to have neither a front end wall VE nor a rear end wall HE. In this case, the silencer housing 11 can likewise be pushed either from above (as shown in FIG. 1) or from the front onto the silencer insert 50. In this case, the silencer insert 50 is closed at its rear side (on the side facing the firearm barrel 91) and at its front side in a gas-tight and pressure-tight manner and has, on the front and rear sides, a respective opening corresponding to the shot channel 20 of the silencer insert 50.

[0056] In one embodiment of the invention, the silencer housing 11 can also have a largely circular profile, as also shown in a section C-C in FIG. 1. The silencer housing 11 can thus be designed to be largely cylindrical, wherein the “cylinder” in its cylinder wall has to have only one recess 46 which extends in parallel to the longitudinal axis of the “cylinder” and preferably over the entire length of the “cylinder.” In this case, the silencer housing 11 has only a front end wall VE, so that the silencer housing 11 can be pushed from the front onto the silencer insert 50. In this case, the silencer insert 50 is closed in a gas-tight and pressure-tight manner on its rear side (on the side facing the firearm barrel 91) and has there only one opening that corresponds to the shot channel 20 of the silencer insert 50.

[0057] The two sections A-A and C-C shown in FIG. 1 are merely intended to illustrate that the silencer housing 11 can have different profiles.

[0058] In a very particular embodiment of the invention, however, it can also be provided that the profile of the silencer housing 11 changes over the length of the silencer housing 11, for example from a profile according to section C-C into a profile according to section A-A. This can be advantageous if the cross section of the silencer insert 50 changes over its length.

[0059] If the silencer housing 11 has a rear and/or a front end wall, a respective opening 25 is provided in these end walls and is arranged coaxially with the firearm barrel 91 when the silencer 10 is attached to the portable firearm. The opening 25 formed in the rear end wall HE can be designed such that the front end of a firearm barrel can engage therein or be brought into engagement therewith.

[0060] In the silencer insert 50, a shot channel 20 is formed, which is likewise arranged or extends coaxially with the firearm barrel 91 when the silencer 10 is attached to the portable firearm 90.

[0061] The attachment rail 30 is arranged on the lower side of the silencer insert 50 and extends here in the longitudinal direction, i.e., in parallel to the longitudinal axis LA of the silencer insert 50 over the entire length of the silencer insert 50. However, it is also possible for the attachment rail 30 to extend only over a partial region below the silencer insert 50. In both cases, the attachment rail 30 projects beyond the silencer insert 50 on the rear side of the silencer insert 50. With the portion of the attachment rail 30 projecting on the rear side of the silencer insert 50, the silencer 10 is attached to the portable firearm, preferably to a mounting rail 94 (e.g., on a Picatinny rail) of the portable firearm 90.

[0062] In an alternative embodiment, the attachment rail 30 can also be arranged on the rear end wall of the silencer insert 50 and extend there in the longitudinal direction in parallel to the longitudinal axis LA of the shot channel 20 of the silencer insert 50. In this case, the underside of the silencer insert 50 is designed such that it is gas-tight and pressure-tight.

[0063] In the embodiment shown here, the attachment rail has a U-shaped profile. Longitudinal guides 32, which extend in parallel to the longitudinal axis of the attachment rail 30, are provided on each of the two side walls 31 of the U-shaped attachment rail 30.

[0064] The section B-B shows the cross section of a silencer insert 50. A shot channel 20 is formed in the silencer insert 50, as explained above. The outer profile of the silencer insert 50 is designed such that the silencer housing 11 can be pushed or placed onto the silencer insert 50. In a preferred embodiment of the invention, the outer profile of the silencer insert 50 is designed such that the silencer housing 11 can be pushed or placed onto the silencer insert 50 in a largely form-locking manner.

[0065] Locking means 45 may be provided on the silencer housing 11 and on the attachment rail 30 or on the silencer insert 50 and can be used to lock or detachably attach the silencer housing 11 to the attachment rail 30 or to the silencer insert 50. The locking means 45 may comprise boreholes in the silencer housing 11 and bores (e.g., blind holes) corresponding thereto in the attachment rail 30 or in the silencer insert 50, for receiving attachment screws.

[0066] The silencer housing 11, the silencer insert 50 and/or the attachment rail 30 are designed such that after the silencer housing 11 has been placed onto the silencer insert 50, the silencer insert 50 is located in a chamber that is designed to be largely gas-tight and pressure-tight, wherein the chamber is formed by the silencer housing 11 and the attachment rail 30 or a lower termination of the silencer insert 50. Only the openings 25 are still present.

[0067] The silencer housing 11 can have guide grooves or guide springs which correspond to guide springs or guide grooves provided on the attachment rail 30 and/or on the silencer insert 50, wherein the guide grooves and guide springs are designed to push the silencer housing 11 onto the attachment rail 30 and/or onto the silencer insert 50. Alternatively, the guide springs and guide grooves may each be arranged such that they may be brought into engagement with one another when, for example, the silencer housing 11 is placed onto the silencer insert 50 from above, as shown in FIG. 1. On the one hand, the guide springs and guide grooves ensure that the silencer housing 11 is pushed or placed safely. On the other hand, they contribute to the gas and pressure tightness when the silencer housing 11 is placed onto the silencer insert 50.

[0068] The rear end portion 35 of the attachment rail 30 is designed such that it rests in a form-fitting manner at least in portions on the trigger guard of the portable firearm when the silencer 10 is attached to the portable firearm 90. Details in this respect are described with reference to FIG. 4.

[0069] On the underside of the attachment rail 30, a mounting rail can be provided, to which accessories can be attached, for example a laser unit or the like.

[0070] FIG. 2 shows a silencer 10 according to the invention which is arranged on or attached to a mounting rail 94 of a portable firearm. The silencer 10 is pushed onto the mounting rail 94 with the portion of the attachment rail 30 protruding on the rear side of the silencer insert 50. In the state attached to the portable firearm, the shot channel 20 of the silencer insert 50 and the openings 25 in the silencer housing 11 extend coaxially with the firearm barrel 91.

[0071] The mounting rail 94 of the portable firearm is arranged on the underside of the handpiece of the portable firearm and below the locking piece 93 of the portable firearm. The mounting rail 94 extends substantially in parallel to the firearm barrel 91 and can extend up to the trigger guard.

[0072] The firearm barrel or the front end of the firearm barrel 91 projects here into the opening 25 of the silencer housing 11, wherein it can be advantageous if the front end of the firearm barrel 91 closes this opening 25 in a largely gas-tight and pressure-tight manner.

[0073] FIG. 3 shows a perspective view of a silencer 10 according to the invention, wherein the silencer housing 11 is pushed or placed onto the silencer insert 50. Depending on the specific embodiment, the silencer housing 11 can be placed onto the silencer insert 50 from above or from the front. Accordingly, the silencer housing 11 can also be removed from or pulled off the silencer insert 50 upward or forward. The silencer housing 11 is detachably attached to the silencer insert 50 or to the attachment rail 30 by means of the locking means 45. Here as well, the attachment rail 30 and the silencer insert 50 are designed according to the invention in one part or in one piece.

[0074] In the embodiment of the attachment rail 30 shown in FIG. 3, each side wall 31 has an axially extending guide joint 32, which extends substantially over the entire length of the attachment rail 30. These guide joints 31 correspond to guide grooves of the mounting rail 94 of the portable firearm.

[0075] It is particularly advantageous if the inner profile of the attachment rail 30 is adapted to the outer profile of the mounting rail 94 of the portable firearm.

[0076] A transverse channel, which extends substantially in parallel to the transverse axis of the silencer 10, is formed in a lower region of the attachment rail 30. The transverse channel is provided for receiving a latching or locking device, which is not shown here, for locking the silencer or the attachment rail 30 to the mounting rail 94 of the portable firearm. With the latching or locking device, it is ensured that the silencer 10 cannot detach from the firearm by itself.

[0077] The longitudinal guides 32 shown in FIG. 3 may extend over the entire length of the region of the attachment rail 30 protruding on the silencer insert 50. However, it is also possible for the longitudinal guides 32 to extend only over a particular region, which ultimately depends on the specific design of the corresponding longitudinal guides of the mounting rail 94 of the portable firearm. It is only important that the longitudinal guides 32 of the attachment rail 30 correspond to corresponding longitudinal guides on the mounting rail 94 of the portable firearm.

[0078] With the silencer shown here, a particularly fast and particularly simple assembly of the silencer on a portable firearm is possible. This is because the silencer only has to be pushed onto the mounting rail of the portable firearm, which is provided below the barrel.

[0079] In that the silencer is not attached to the moving slide/lock or to the moving barrel but to the frame or the gripstock of the portable firearm or to the mounting rail of the portable firearm, the barrel can move backward independently of the silencer, so that a self-loading function of the firearm is not impaired by the silencer.

[0080] FIG. 4 shows a rear end portion 35 of the attachment rail 30 of a silencer 10 according to the invention in a perspective view.

[0081] A supporting surface is formed at the rear end and is substantially perpendicular to the longitudinal axis LA of the attachment rail 30. Furthermore, the supporting surface extends between two wings formed at the rear end, wherein the wings are arranged substantially perpendicularly to the supporting surface and extend in parallel to the longitudinal axis of the attachment rail 30. The two wings protrude backward on the supporting surface.

[0082] The supporting surface 36 itself here has a convex surface and is designed such that it corresponds to a concave surface of a trigger guard of a portable firearm. When assembling the silencer 10 according to the invention on the portable firearm, the convex surface of the attachment rail 30 and the concave surface of the trigger guard come into “engagement,” so that the convex surface rests in a substantially form-fitting manner on the concave surface. The concave surface of the trigger guard thus forms a counter supporting surface, which prevents the silencer 10 from tilting downward at the front after a shot is fired.

[0083] The distance between the two wings is selected such that it substantially corresponds to the width of the front end of the trigger guard of the portable firearm.

[0084] FIG. 5 shows a perspective view of a silencer 10 according to the invention in a sectional view along the longitudinal axis of the silencer 10.

[0085] Shown here is the silencer housing 11, which is arranged detachably from the silencer insert 50 and here has two side walls, a front and a rear end wall and an upper wall extending between the two side walls and the two end walls.

[0086] In the interior of the silencer housing 11, the silencer insert 50 is arranged, which here is also designed according to the invention in one part or in one piece with the attachment rail 30. The silencer housing 11 shown here can be pulled off the silencer insert 50 upward or forward.

[0087] The silencer insert 50 has a number of ribs 51. In the silencer insert 50, a shot channel is formed, which extends between the openings 25 in the silencer housing 11 and extends coaxially with the firearm barrel when the silencer 10 is attached to the portable firearm.

[0088] FIG. 6 shows a further exemplary embodiment of a silencer 10 according to the invention.

[0089] The silencer 10 consists substantially of a silencer housing 11 and an attachment rail 30, wherein the attachment rail 30 protrudes on the side of the silencer insert 50 facing the firearm barrel of the portable firearm. In this embodiment, the silencer insert 50 and the attachment rail 30 are also designed in one part or in one piece and thus together form an integral unit.

[0090] A rear end portion 35 of the attachment rail 30 is adapted such that the silencer 10 can be attached to the locking piece 93 (slide) of the portable firearm. The end portion 35 of the attachment rail 30 is preferably designed such that the silencer 10 can be detachably attached to the locking piece of the firearm.

[0091] Here, the rear end portion has a substantially U-shaped profile, wherein the open side of the profile is located at the lower side of the end portion 35. In an advantageous embodiment of the invention, the profile of the rear end portion 35 is designed such that it largely corresponds to the outer profile of the locking piece (in particular to the front end portion of the locking piece) of the portable firearm. The rear end portion 35 of the attachment rail 30 can then be placed or pushed onto the locking piece of the portable firearm.

[0092] In one embodiment of the silencer 10 according to the invention shown in FIG. 6, latching means, for example latching pins, may be provided on or in the profile and can be brought into engagement with corresponding latching means on the locking piece, so that after being pushed onto the locking piece, the silencer 10 is locked to the locking piece.

[0093] Here, the silencer housing 11 can be pushed or placed onto the silencer insert 50 from below or from the front.

[0094] It is substantial for the present invention that the silencer insert 50 and the attachment rail 30 are designed in one part or in one piece, and the silencer housing 11 may be placed or pushed onto the silencer insert 50.

[0095] FIG. 7 substantially shows the silencer shown in FIG. 3, wherein the silencer insert 50 and the attachment rail 30 are also formed in one part or in one piece here. In contrast to the silencer 10 shown in FIG. 3, the silencer housing 11 comprises two plates 40, wherein the one plate 40a is attached from the left side to the silencer insert 50 and the other plate 40b is attached from the right side to the silencer insert 50. FIG. 7 shows the silencer 10 according to the invention, to which the two plates 40a, 40b are already attached. The two individually illustrated plates 40a, 40b are only used here for illustration purposes.

[0096] The upper side of the silencer insert 50 can be an integral component of the silencer insert 50. Alternatively, a plate 40 can also be provided on the upper side of the silencer insert 50 and is then likewise part of the silencer housing 11.

[0097] In a further embodiment, however, the silencer housing 11 can also comprise only one plate 40, which is attached to the silencer insert 50 either from the left, from the right, or from above.

[0098] According to the embodiment shown in FIG. 7, the silencer housing 11 can comprise [0099] one plate, [0100] two plates, or [0101] three plates.

[0102] The plates are detachably attached to the silencer insert 50 and/or to the attachment rail 30 by means of locking means 45.

[0103] The front and the rear end face of the silencer insert 50 may likewise be covered by means of plates of the silencer housing. However, this is not absolutely necessary, since these plates do not have to be removed for maintaining the silencer insert 50. It is substantially sufficient if one of the plates extending between the two end faces is removed from the silencer insert 50.

[0104] In all of the above-shown embodiments of the silencer 10 according to the invention, it is advantageous if after the silencer housing 11 has been fastened to or pushed onto the silencer insert 50, the silencer insert 50 is located in a pressure-tight and gas-tight chamber, wherein this chamber is formed by the silencer housing 11 and the attachment rail 30. The individual openings of this chamber, which is otherwise pressure-tight and gas-tight, are the openings 25.

[0105] FIG. 8 shows an example of a silencer insert 50 of a silencer 10 according to the invention in a sectional view along the longitudinal axis of the silencer insert 50.

[0106] The silencer insert 50 here has a number of ribs 51, which are at least partially obliquely inclined backward, and wherein some of the ribs have longitudinal bores 52. In the upper region of the ribs, the shot channel 20 is formed, so that the projectile can pass unhindered through the silencer insert 50. The structure, number and design of the ribs 51 can deviate from the ribs 51 shown in FIG. 8 and substantially depend on the specific requirements for the damping properties of the silencer.

[0107] The silencer insert 50 shown in FIG. 8 is shown without the attachment rail 30. Of course, the silencer insert 50 shown in FIG. 8 is also arranged according to the invention on an attachment rail 30 in such a way that the silencer insert 50 and the attachment rail 30 are designed in one part or in one piece.

[0108] In the above-shown embodiments according to the invention of a silencer 10, the silencer insert 50 and the attachment rail 30 have a substantially L-shaped shape, wherein the one leg is formed by the rear protruding portion of the attachment rail 30 and the other leg is formed by the silencer insert 50.
