Definitions

  • the invention relates to a silencer for a firearm, comprising an assembly consisting of a damping element with an expansion chamber, and with a connecting device for connecting the assembly to a firearm.
  • a generic muffler is from the DE 44 10 625 A1 known. Further mufflers for firearms and devices for connecting the same with the firearms are, for example, in DE 100 01 374 C1 or the DE 10 2014 119 734 A1 described.
  • the known muffler have several disadvantages: Firstly, the connection between the muffler and the weapon is usually solved by a thread that, although a fairly simple, but very time-consuming connection between these two components.
  • the muffler according to the invention has a connection device for connecting the muffler with the firearm and allows a very simple and fast connection of these two parts, so that the muffler according to the invention is ready for use within a very short time.
  • a mounted muffler has the further advantage that it has a very firm and secure fit to the firearm.
  • a separately formed connecting device for connecting the assembly to the firearm wherein the connecting means is provided for a particular releasable connection to the end of a firearm barrel, and on the other for releasable connection to the assembly has at least one projection, which to interact with a molding on the assembly by means of a positive guide by overcoming a spring force in the direction in which a positive engagement is engageable, so that the assembly is held on the connecting device, wherein the assembly at least two with the connecting device cooperating, in particular symmetrically to each other and oppositely arranged bolts (20) as a formation which extend in an aligned at least approximately perpendicular to a longitudinal axis of the muffler plane spaced from each other, and at least two arranged on a provided for engagement with the bolt engaging member having projections, wherein the engagement member has a width which is less than the distance of the bolts, and wherein the projections have such an extent that they engage behind the bolts after insertion of the engagement element between the bolt
  • the silencer according to the invention can be easily attached to the firearm via the connecting device and removed again.
  • it is only necessary to connect the connecting device with the firearm which can be done via a screw on a thread introduced at the firearm barrel on its circumference.
  • connection means with the two bolts and the same in the locking position behind engaging projections on the engagement element results in an easy to implement embodiment and it is on the other hand a smooth operation of the same during locking and unlocking guaranteed.
  • the bolts must only be inserted through bores formed perpendicular to the running direction. This simplifies the production.
  • the design is advantageous in that a rotation by at least 90 ° for a latching must be carried out.
  • the assembly consists of a damping element, which has an expansion chamber and a reflection chamber, with a cladding tube surrounding the damping element.
  • At least one elastic ring is arranged, which is compressed at least in the end position of the connecting device in the positive position and thus the spring force in the direction of the connecting device against the assembly exercises.
  • this sealing ring also reduces the penetration of dirt into the muffler and the discharge of gas from the muffler.
  • the projections have a respective inclined surface, which leads to a Verrastnut, in which the bolts are in their engagement with the engagement member.
  • a sealing ring for sealing against the Expansion chamber is arranged, since in this way the escape of gases in the direction of the user of the firearm is prevented.
  • a molding in particular in the form of a grub screw, which in an asymmetric engages formed at the connection device exemption.
  • the connecting bores extending from a firing channel to the expansion chamber and / or the reflection chamber are radially widening, in particular funnel-shaped , are designed.
  • the expansion module detachable from the muffler, in which the expansion chamber is arranged it is possible to achieve a reduction in the overall length of the muffler, since the expansion module can be located outside the barrel of the firearm, so that the muffler in principle passes over the firearm to which it is mounted extends.
  • the silencer per se is longer than in known solutions, but the overall length of the firearm with the mounted on the same silencer does not exceed the length of known solutions.
  • a simple gas exchange between the expansion module and the expansion chamber results when the expansion module is connected by means of a plurality of openings with the expansion chamber.
  • Fig. 1 shows in a very schematic representation of a firearm 1, to which a muffler 2 is attached.

This is in Fig. 3 detailed. This results in that the at least one elastic ring 27, 29 is compressed in the end position of the connecting device 19 in the positive-locking position and so the spring force is exerted in the direction of the connecting device 19 against the assembly. See the history of the Fig. 6 to 10 and afterwards 2.
