Definitions

  • the present invention relates to the field of silencers for firearms.
  • Silencers for firearms serve the purpose of reducing noise emissions due to the expansion of emerging from the muzzle gases, the so-called muzzle blast.
  • Mufflers can typically be threadably attached to a thread on the barrel or tube of the weapon. Alternatively, in some cases, they are firmly attached to the weapon by the manufacturer.
  • Noise reduction is desirable in some applications: examples of uses of mufflers include hunting in inhabited areas or avoiding game disturbance. They also serve to protect the hearing health of police or military task forces.
  • Conventional mufflers have some common characteristics. First, they consist of several individual parts, which are held together by a sleeve or a piece of pipe. These items are typically made of different materials. Further, conventional mufflers are rotated and milled by conventional manufacturing techniques.
  • a conventional silencer is known for example from the German patent DE 17 03 420 B2 known.
  • a multi-part muffler which has a plurality of divided by inserts expansion chambers.
  • several, mutually supporting inserts are surrounded by a piece of pipe and held together.
  • the object of the present invention is to at least partially reduce the aforementioned disadvantages of conventional silencers.
  • the devices according to the invention are firearm silencers, hereinafter referred to as silencers.
  • a device comprises a main body.
  • This main body is formed as a one-piece body extending around a central longitudinal axis and defines at least one expansion space formed coaxially with respect to the central longitudinal axis.
  • a layer-by-layer manufacturing method, i. layered, construction serves to achieve the objective of the invention of a compact, lightweight, material and / or cost-saving design, and / or the opening of new, inventive geometries and designs.
  • the central longitudinal axis preferably coincides with a projectile path of a projectile fired from a mounted firearm.
  • the main body which can be produced as a one-piece body is one-piece insofar as it preferably consists of a homogeneous material and / or does not require any assembly steps as is the case with conventional mufflers consisting of several components.
  • Expansion spaces are cavities formed in the main body which can accommodate the expansion of gases. These gases can escape from a muzzle of a firearm. Without muffler mounted on the muzzle, the uncontrolled expansion of these gases leads to the muzzle blast.
  • Silencers according to the invention comprise at least one expansion space, which is formed coaxially to the central longitudinal axis. Expansion rooms can be designed as sound guiding rooms. The term expansion space should not be understood as a description of a particular geometry.
  • coaxial bodies, spaces, etc. in the sense of the present invention need not necessarily be rotationally symmetrical about the respective axis.
  • coaxial expansion spaces establish an at least partial structural alignment.
  • the main body defines at least two expansion spaces which are coaxial with respect to the central longitudinal axis.
  • the main body is further formed in layers in the direction of the central longitudinal axis.
  • the main body can preferably be produced by means of one of the following production methods for setting up in the direction of a central longitudinal axis: a 3D printing method, a stereo lithography method, a selective laser sintering method, a casting method or a forming method.
  • a selective laser-sintering process whereby, for example, a metal is selectively sintered using a laser, i. connected and compacted, becomes. This process is preferably carried out in layers. After sintering the material of one layer, the unsintered starting material of the next layer is applied and then again sintered by laser. Due to symmetry and static considerations, it is particularly advantageous to produce the muffler layer by layer along the direction of a central longitudinal axis, which corresponds to the projectile path.
  • the main body defines at least one of the following elements: an outer wall bounding the at least one expansion space to the outside; walls extending coaxially with respect to the central longitudinal axis defining the at least one expansion space; at least partially perpendicular to the central longitudinal axis extending webs; at least partially coplanar to the central longitudinal axis extending support structures; a thread for connection to the barrel of a firearm or an interface for connection to the barrel of a firearm; a mouth opening; a firing channel extending through the main body in the direction of the central longitudinal axis.
  • An outside wall can serve the external appearance of the silencer with a brand or company logo. Furthermore, it can be used by the user to facilitate handling. The user can grasp the outer wall to attach the muffler to a firearm.
  • Walls, webs and support structures can each serve for the stable statics and / or the direction of the flow behavior of expanding gases.
  • a thread can serve the simple, fast, gas-tight and / or secure connection with a firearm.
  • This connection can be made directly or indirectly.
  • This connection can be made directly with the barrel of the firearm.
  • this connection can be made indirectly via a suitable adapter or a different interface for connection to the barrel of a firearm, such as a quick-release.
  • An orifice serves to eject a projectile from the silencer.
  • a firing channel serves the unobstructed path of a projectile and as the primary flow direction of expanding gases.
  • At least one of the expansion spaces may be curved.
  • returns and / or courses of expansion spaces with turns, curves, etc. possible.
  • Curvatures of expansion spaces according to the invention may preferably be embodied in various forms. These bends may include components or portions in one or more of the following directions: azimuth, radial, axial.
  • the directional designations mentioned are preferably based on essentially cylindrical silencers. The skilled person is familiar with the use of cylindrical coordinate systems with regard to cylindrical geometries. The three dimensions are described here by an azimuthal, radial and axial unit vector.
  • a curvature can be described locally by a tangent vector.
  • the tangent vector can be decomposed in the cylindrical coordinate system into components or proportions with respect to said unit vectors. Accordingly, a curvature component is oriented in the azimuthal direction about the central longitudinal axis.
  • a curvature component in the radial direction is oriented away from the central longitudinal axis.
  • a curvature component in the axial direction is along or parallel to the oriented along the central longitudinal axis. Exemplary curvatures in one or more of the mentioned directions are explained in the exemplary embodiments.
  • At least one of the expansion spaces may have a taper and / or a broadening in its cross section. Rejuvenations and / or broadening of the cross section can be used according to the invention to control the expansion of the gases. They lead to increased or reduced flow velocities and can thus have an influence on the damping of the muzzle blast.
  • one or more expansion spaces can open into a sound-absorbing area.
  • a sound absorption area can take various forms.
  • Sound-absorbing-area forms of the present invention include porous-fabricated areas or areas of foam structure.
  • a sound-absorbing region may be formed as a sack-like termination of an elongated expansion space. The expansion energy of the expanding gas or sound generated by gas expansion are absorbed in whole or in part by such sound absorption areas. By ramification and / or long expansion spaces, the ratio of absorbing surface to expansion volume can be optimized.
  • one or more expansion spaces may be opened toward an outer wall of the main body.
  • Such openings to an outer wall allow a portion of the expanding gases after flowing through one or more expansion spaces, the outflow into the environment.
  • the resulting bang when flowing out is at least reduced or completely suppressed.
  • Openings of expansion spaces toward an outer wall of the main body may be formed at various locations of the outer wall. In particular, it is conceivable, for example in the case of a substantially cylindrical main body, to provide these openings on one or both end faces of the cylinder and / or on the lateral surface of the cylinder.
  • one or more expansion spaces may be open towards the central longitudinal axis.
  • This opening may be formed towards the firing channel.
  • this opening may be opposite to the weft direction.
  • several of the expansion spaces may merge in their course. This is advantageous, for example, if an expansion space or a few expansion spaces have openings to an outer wall or to the central longitudinal axis.
  • other expansion spaces may unite in their course with the expansion spaces with openings, so that the gases which expand in them can also escape through said openings. Among other things, this can lead to a more compact design and / or a weight saving compared to a construction without unification of expansion spaces.
  • At least one of the expansion spaces may branch in its course. This is advantageous, for example, if the expanding gases of a single expansion space are to be routed to two different destinations.
  • These objectives may include, but are not limited to, one or more of the above-mentioned sound-absorbing areas, one or more of the above-mentioned exterior wall openings, and / or one or more central longitudinal axis openings.
  • the branching of an expansion space is particularly advantageous, with one branch having an opening to the outer wall and a second branch having an opening to the central longitudinal axis.
  • expansion spaces as helices coaxial about the central longitudinal axis.
  • two expansion spaces can be arranged as a double helix, three expansion spaces as a triple helix, etc.
  • expansion spaces wherein a plurality of the expansion spaces concentrically surround each other.
  • a compact and material-saving design can be achieved.
  • a wide distribution of lengths of expansion spaces can be achieved.
  • the stretches or volumes to be traversed by expanding gases in the expansion spaces have a broad distribution.
  • any returns to the central longitudinal axis can be done in reverse order. For example, details will be explained below with reference to preferred embodiments.
  • a method of manufacturing a firearm muffler according to the present invention comprises building material along a central longitudinal axis for a one-piece main body such that at least one expansion space is formed coaxially with respect to the central longitudinal axis.
  • the building up of material preferably proceeds in layers in the direction of the central longitudinal axis.
  • the production of each layer is two-dimensionally rastered perpendicular to the central longitudinal axis. This two-dimensional rastering particularly preferably takes place in a Cartesian or polar coordinate system.
  • the fabrication is done using a single source material.
  • This starting material may more preferably be a metal.
