Definitions

  • the invention relates to a barrel unit for a firearm comprising a barrel and a locking sleeve, which are releasably connected to one another and subsequently to the housing, usually the upper part of the housing, and the connection of the two parts, according to the preamble of claim 1 and the EP 1 750 079 A1 .
  • the EP 1 750 079 A1 discloses a barrel unit for a firearm, comprising a barrel with a barrel core axis, a muzzle and a barrel end opposite the muzzle, on which at least two barrel lugs are formed, with a locking sleeve with a barrel receptacle and a first end and a second end, being at the first end inwardly extending locking lugs are formed to cooperate with a breech and inwardly extending barrel locking lugs are formed closer to the second end than the locking lugs.
  • firearms is understood to mean, in addition to carbines, repeating rifles, rifles, long guns, and the like. In principle, it can also mean handguns, but for reasons of easier readability, we usually only refer to carbines.
  • a barrel unit which includes at least the barrel and locking sleeve.
  • the running unit in turn can be connected to the housing, for example by means of a running nut, clamping mechanism, etc.
  • a common way to couple a barrel to a locking sleeve is through threaded connections.
  • the barrel has an external thread at the muzzle end, and the locking sleeve also has a corresponding internal thread.
  • the barrel can simply be screwed into the locking sleeve.
  • the barrel can be secured against twisting using, for example, cross bolts or grub screws, etc., as shown in the GB 268 996 A is known.
  • Such a coupling between the barrel and the locking sleeve can be found, for example, in rifles of the M4 / M16 / AR15 type.
  • Another known variant for coupling the barrel and locking sleeve takes place using the principle of locking lugs, as is known from rotary head locks, for example.
  • Corresponding barrel lugs are formed on the outside of the barrel in the circumferential direction; the locking sleeve has identical barrel locking lugs directed inward. After inserting the barrel into the locking sleeve, the barrel is rotated, bringing the barrel lugs and barrel locking lugs into alignment when viewed in the axial direction. The barrel and locking sleeve are thus secured in the axial direction.
  • the barrel can be secured against twisting, for example using a cross bolt or grub screw, etc.
  • the barrel unit which consists at least of a barrel and a locking sleeve, has a barrel that begins on the outer surface at the barrel end and is at least partially in Circumferential direction includes control path extending around the barrel axis.
  • the control path comprises at least two sections, the first section beginning at the end of the barrel and extending parallel to the barrel core axis and the second section extending in the circumferential direction, and the second section having a clamping surface for clamping a control cam arranged on the locking sleeve.
  • Clamping surface and control cam (or the surface of the control cam facing the clamping surface) are designed to complement each other in shape.
  • the second section may be directly connected to the first section, or a third connecting section may be provided therebetween.
  • the control cam comes to rest in a predefined end position, the control cam being prestressed in the radial direction towards the barrel core axis and the barrel being fixed in the locking sleeve.
  • the predefined end position therefore corresponds to a position of the barrel that is ready to fire and temporarily secured against rotation.
  • the barrel is therefore relatively easy to insert into the locking sleeve and can be rotated into the predefined end position, in which the barrel is firmly and releasably connected to the locking sleeve, i.e. coupled, by clamping the control cam on the clamping surface.
  • This advantageous design allows the barrel and locking sleeve to be connected to one another simply by inserting them into one another and twisting them into the predefined end position.
  • the barrel In a predefined end position, the barrel can transfer the forces that occur when the shot is fired to the locking sleeve, which in turn is firmly connected to the housing. While with a threaded connection the alignment in the circumferential direction depends heavily on how far the barrel is screwed into the locking sleeve, any deviations in the hit position in the horizontal and/or vertical direction can be minimized in the manner mentioned above.
  • the hit position for a specific barrel is now determined and the firearm is thus "shot in” at a distance, repeatable positioning of the barrel in the circumferential direction can be achieved even after the firearm has been dismantled using the predefined end position. If necessary and by twisting in the opposite direction
  • the barrel can be released from the locking sleeve relatively easily. No tools are required to connect and disconnect the barrel and locking sleeve.
  • the prestressed fixation of the control cam on the clamping surface can be carried out, for example, by spring preloading a spring of the control cam.
  • the control cam can also be made of an elastic material. However, it is also possible to reverse the direction of action and, for example, to design the clamping surface (or even clamping surface and control cam) as a spring-loaded element.
  • the clamping surface is designed as a ramp when viewed in the running direction. Viewed in the running direction, the clamping surface at one end has a different normal distance from the barrel core axis than the other end. This allows a stepless transition from the control path to the clamping surface to be achieved and the barrel can be turned particularly easily into a predefined end position. Furthermore, the clamping effect can increase in a defined manner when twisting by appropriately designing the ramp shape and/or slope, and is therefore easily noticeable by the operator.
  • the ramp of the clamping surface viewed towards the end of the control path, is designed to rise linearly outwards in the radial direction.
  • the clamping surface therefore increases linearly in the circumferential direction and outwards, which is advantageous in terms of production technology.
  • the second section of the control path can be curved when viewed in the direction of travel, for example with at least two different curve lines, for example S-shaped.
  • the clamping effect when twisting can be specifically preset by a person skilled in the art using such a measure and, for example, defined to different degrees depending on the angle of twist and/or optimized for particularly long barrels with a corresponding weight.
  • the clamping surface is a curved surface, for example as a concave surface relative to the running surface. This allows the clamping effect to be particularly optimized.
  • the profile of the surface appears curved and can be seen from Transition area to the first or possible third section up to the end of the clamping surface, for example, has an inwardly directed curvature or rises discontinuously outwards. In this way, it is even possible to design this concave surface to be similar to a rest, which makes it particularly easy for the operator to recognize that the predefined end position has been reached.
  • a catch is formed on the clamping surface for cooperation with the control cam or a catch extension of the control cam.
  • the catch can, for example, be designed as a small recess in the middle of the clamping surface.
  • a correspondingly complementary locking extension on the control cam can engage in this lock when the predefined end position is reached and thus defines the end point of the twisting movement. This makes it particularly easy for the user to see when the predefined end position has been reached.
  • the stop can also be designed as a small step at the beginning of the clamping surface, which interacts with the control cam.
  • the catch can also be designed as an end stop at the end of the control path.
  • an end stop can be formed on the clamping surface. This end stop limits the possible movement of the control cam in the second section of the control path in the circumferential direction. This means that the predefined end position is particularly easy for the user to recognize, namely when the end stop is reached.
  • first section and the second section of the control path are connected to one another by means of a connecting section or preferably directly.
  • This shape of the control path, or its first section is particularly easy to produce, since, for example, only one groove running linearly to the rear and one groove in the circumferential direction need to be milled.
  • This also has an advantageous effect when guiding the barrel and locking sleeve into one another, since the barrel and locking sleeve can be inserted straight into one another and twisted and the predefined end position can thus be reached.
  • the second section of the control path is designed at right angles to a straight line parallel to the barrel axis. After being guided into one another, the barrel and locking sleeve only need to be twisted against each other in order to reach the predefined end position.
  • a second section designed in this way can also be produced very easily as a linear groove in the circumferential direction, for example by milling, and essentially corresponds to an “L-shape” when viewed from the outside in plan view.
  • a particularly favorably designed design of the running unit can have a first distance between two adjacent running lugs that is larger than a second distance between two adjacent running lugs.
  • the first distance can essentially correspond to the width of the control cam.
  • the width of the control cam must be smaller than the first distance and should be larger than the second distance.
  • control cam is arranged in the locking sleeve using a control cam holder.
  • the control cam can be connected to the control cam holder as a unit, i.e. as its own “sub-assembly”. be designed, which is thus installed together and simultaneously in the locking sleeve. This is advantageous in production and handling.
  • control cam is formed integrally on the control cam holder. This reduces the number of parts and accordingly simplifies production and reduces manufacturing costs. Assembly is quicker and easily lost parts are avoided.
  • control cam can be manufactured integrally on the control cam holder, for example as a stamped sheet metal part.
  • control cam holder is designed as a spring, particularly preferably as a leaf spring, and biases the control cam in a predefined end position against the clamping surface.
  • a leaf spring can be arranged in the locking sleeve even if there is little space; leaf springs are generally highly resilient and particularly wear-resistant.
  • the spring preload results in a particularly high clamping effect in the predefined end position, which has a particularly advantageous effect in the operation of the firearm
  • control cam holder can be self-clamping and releasably connected to the locking sleeve in the working position.
  • the self-clamping is achieved through tight tolerances between the control cam holder and the locking sleeve and allows connection without connecting elements such as screws, etc. and if necessary, the control cam holder can be released from the locking sleeve and replaced.
  • small lateral extensions can be formed on the control cam holder, which are placed in a corresponding retaining groove in the locking sleeve. Self-clamping is achieved due to the close tolerance between the extension and the retaining groove.
  • a holder stop is formed on the control cam holder to engage in an indentation on the locking sleeve in order to secure the control cam holder in the working position in the locking sleeve.
  • the control cam holder is secured in this way against axial displacement and thus against loss from the locking sleeve.
  • a further aspect of the invention is that the barrel has an indentation which can interact with an additional anti-rotation element of complementary shape.
  • additional anti-rotation protection of the barrel can be implemented, for example, by means of a bolt located transversely to the barrel core axis.
  • the additional anti-rotation element is designed as a cam of a clamping lever, which is designed to complement the indentation.
  • the indentation can, for example, be designed as a flattened area in the barrel.
  • the cam can be designed to be flattened in the transverse direction and/or running direction. In this way, upon contact between the barrel and the cam, force is transmitted in a linear or flat manner, which results in improved anti-twist protection. This is particularly advantageous in designs that already connect the locking sleeve to the housing using a clamping mechanism with a clamping lever.
  • the cam and the flat are spatially separated from one another by a gap, the gap preferably having a width of 0.02 mm to 0.4 mm, particularly preferably 0.10 mm to 0.20 mm .
  • the gap ensures that the barrel swings freely and is not undesirably distorted by the cam.
  • the anti-twist protection only works if the barrel is actually twisted.
  • the invention is suitable for firearms, including pistols, but will be explained below using a carbine. Further components of the firearm, such as the barrel, cartridge chamber, locking sleeve, locking lugs, magazine or stock are not explained in more detail here, as they do not relate to the core of the invention and the person skilled in the art with knowledge of the invention, if at all necessary or desired, Can make modifications simply based on his expertise.
