Definitions

  • the invention relates to an arrangement of shotgun barrel and Barrel for a shotgun, and a method for its manufacture of such a barrel provided with a running rail.
  • shotguns To be able to easily grasp a target, you bring it to the top of the barrel, which is aimed at when shooting a running track. This extends at least over part of the barrel and is fixed to the barrel or fixed adjustable connected.
  • Running rails are usually on single-shot shotguns (Barrel shotguns, repeating shotguns or self-loading shotguns) or over-and-under shotguns. It is also possible to use rails in connection with weapons, in which two - and theoretically more - runs lying on top of or next to each other, such as double shotguns, Over-and-under rifles and over-and-under rifles. Even on one-row Rifles (such as break barrel or bolt action rifles) often a running machine attached.
  • the running track can a flat surface or one that is bent downwards Have surface (so-called hollow rail).
  • the cross section a track can go up (towards the line of sight) be limited in a straight line or curved so that the running rail to a certain extent forms a flat channel.
  • ventilated runners which on their adjacent to the barrel Side recesses have. These can be from cooling air are flowed through and thus provide ventilated Gaps between parts of the track and the top of the barrel facing this.
  • the above Gaps are formed by bridge-like sections the track separated from each other, which on reach the barrel and are soldered to it. in the No ventilation occurs in the area of these sections, so that still clear at least at these sections Streaking occurs.
  • Ventilated tracks also have the advantage that they are lighter than solid runners. This will not only reduced the overall weight of the shotgun, but also tracking a moving target with a shotgun facilitated.
  • a disadvantage of the ventilated running track their increased manufacturing costs because of the recesses must be milled out cleanly.
  • the invention now aims to provide an improved arrangement to create from shotgun barrel and running track.
  • the running track should be easy to manufacture and attachable to the barrel his.
  • this goal is achieved through the subjects of Claims 1 or 10 achieved.
  • the running rail for a shotgun from a plastic with poor thermal conductivity, i.e. significantly worse than that of the barrel made of steel exists, and is glued to this barrel.
  • the running rail according to the invention brings about bad heat-conducting plastic that their the line of sight facing surface clearly with hot shot barrel is colder than the other running surface. streaking occurs over the running rail according to the invention so especially in the area of the line of sight, least on.
  • the track prevents that of the neighboring Tread surface caused streaking Line of sight affected, because the heated air can only rise on both sides of the track and thus leaves the Line of sight unimpaired.
  • a running track made of a plastic is included poor thermal conductivity also basically simple to produce, because to reduce streaking no special shape is required.
  • High-strength, heat-resistant adhesive connections for example using epoxy resins are known in the art
  • gluing is not only easy and has a strength that that of a soft solder joint is absolutely the same, but has one when choosing one limited flexible adhesive still has the advantage that it local stresses are distributed and thus reduced.
  • a relatively small surface area is therefore sufficient which the track is glued to the barrel in order for one to ensure lasting and reliable hold of the running track.
  • Thermosetting plastic is preferred 2).
  • the Running track embedded one or more reinforcing means (Claim 3). So even for an improved one Dimensional stability and rigidity ensured if that's the Basic material forming the track, for example, is relatively should be flexible plastic. Such a thing Basic material - at least in the area that corresponds to the Run adjacent - has the advantage that the run is at can expand freely when heated. In addition, the Shape of the running track adapted to that of the running surface become.
  • a metal sheet for example, could be used as a reinforcement which are part of the run surface facing away from and closest to the line of sight Running rail forms and on its surface in the usual Way is roughened, matted or guilloche.
  • the reinforcing means are fibrous. Fibers have the advantage that its course is connected to the course with simple means the track can be adjusted so that the manufacture the running rail according to the invention is simplified.
  • Track can be solid. in this connection it is also essential that an optionally fiber-reinforced Plastic a much lower weight than the steel previously used for the running track. Even then, such a running track does not interfere the rapid targeting with a rifle when they should be unusually high and wide.
  • the Track on its side facing the barrel recesses on (claim 6). So it is similar to the known one ventilated running track. These recesses do not serve, as in the known track, the Ventilation and thus the reduction of streaking, but primarily weight reduction and maintaining the look of a shooter Quality weapon is used.
  • the arrangement of said recesses enables the use of a wider track that if necessary, for example with an ordonance weapon, also as Mounting base designed for additional facilities can be, for example, for a special target device (Red dot sight, laser aiming device, etc.).
  • the invention Track preferred application for single-barrel weapons, which also have repeating shotguns and self-loading shotguns are attributable. But it is also possible to use the invention To use track in connection with weapons where two shotgun barrels are next to each other. in this connection the track can be extended downwards so that it Both sides have pictures for gluing the two shotgun barrels forms.
  • the one according to the invention is particularly advantageous Running track arranged on two superimposed runs.
  • the lower barrel can be a rifle barrel, but is preferred - like the upper barrel - also a shotgun barrel.
  • plastic for the running rail leaves special other colors without any problems simple and permanent by using a colored one Plastic can be achieved, or training colored zones, such as a colored median, for example by applying a colored plastic adhesive preferably by means of a peeling strip.
  • Running track a blank made of glass fiber reinforced plastic inserted in a heatable mold, heated in this, pressed and optionally cured (claim 10).
  • the running rail according to the invention is mixed with fibers it is particularly advantageous to manufacture them made of glass fibers soaked in plastic, so-called prepregs, preform and then heat. In this way can be a particularly economical and easy one Produce complex shaped track. You can the surface facing the line of sight with molded Roughening and the desired surface color the running track by appropriate coloring of the plastic wetting the fibers can be achieved.
  • the shotgun grain in the Usually made as a small ball of metal or plastic whose color contrasts with that of the running track, to insert in the mold and to mold. It is also possible and possibly advantageous, a common one Thread hole for such a grain later in the Insert running rail. So the shooter is allowed to give his weapon a grain of his own choice.
  • the running rail according to the invention can be a separate part manufactured and advantageous on the barrel by means of an adhesive (Claim 11) or an ultrasonic bonding (claim 12) be attached; the first procedure requires only one simple device for clamping the running rail to the Run while the glue hardens while the second one Process has the advantage that it is particularly quick and clean is feasible since no leaked adhesive is removed must become.
  • a shotgun barrel 4 is shown in each of the three figures, whose mouth is in the drawing on the left and its End of the bearing is on the right in the drawing.
  • the Longitudinal dimension of the respective shotgun barrel 4 is strong shortened.
  • a shotgun barrel 4 is shown on the top a ventilated track 2 is attached.
  • This ventilated running rail 2 faces away from running 4 Side on a flat surface.
  • the run 4 side facing the running rail 2 elongated, itself in the longitudinal direction extending recesses 8, so that the running rail 2 the running 4 only with columnar sections between two adjacent recesses 4 touches.
  • the running rail 2 is at these sections glued to barrel 4.
  • the barrel 4 has no cylindrical or consistently conical outer shape, but has one tapering to the extent from the end of the bearing Outside diameter on how it is about the inside pressure at Launch corresponds.
  • the outside diameter increases towards the mouth of barrel 4, however, because it is at its mouth has a holder for interchangeable choke inserts. If such a recording is not planned, then Run 4 tapers to the mouth.
  • the running track 2 is in any case with the barrel 4 facing Side adapted to this.
  • Fig. 2 shows a barrel 4, which is designed as such is like the barrel 4 of Fig. 1.
  • the track 12 differs differs from that of FIG. 1, however, in that it is massive.
  • their area runs that facing away from the barrel, not exactly as with the running track 2 of Fig. 1, but is in the middle of the barrel 4 slightly towards the barrel, forming a hollow rail flexed.
  • the running rail 12 On the mouth side, the running rail 12 has Shotgun 6 on the shotgun 6 of the embodiment corresponds to Fig. 1.
  • the line of sight 18, the from the rear upper edge of the running rail 12 over the Shotgun sight 16 thus does not fall with the running surface together.
  • Fig. 3 shows a run 4, which as such with the previously shown runs 4 matches.
  • the running rail 22 corresponds in its contour essentially the running track 2 1, but does not have recesses 8 like this but is either massive or - for further weight - and material saving - hollow. Further is a coarse bush grain 6 'near the mouth of the running rail 22 with molded.
  • the height y is compared to that Soul axis (central axis of barrel 4) significantly larger than the height x of the track 22 at the mouth.
  • This training is due to the fact that large calibres Shotguns unusually heavy shotgun bullets, tear gas containers or shot shards with a relatively low Speed can be missed so that not only the effective shot distance is low, but also with a very strongly curved trajectory is to be expected. The line of sight must therefore go down towards the axis of the soul be inclined.
  • All the rails 2, 12, 22 shown are made of glass fiber reinforced Plastic.
  • Fig. 4 shows a schematic cross section through a Hollow mold for the production of a running track.
  • the hollow shape is formed from two mold halves 5 and 7, which form a mold cavity Include 9.
  • the two mold halves 5, 7 are either closed State locked together and it becomes a melted Plastic injected into the mold cavity 9, or a prepreg (one with plastic impregnated glass fiber strand) in the open mold cavity 9 inserted. Then the mold halves 5, 7 heated and compressed, with a separate Track 4 designed as a casting or as a compact becomes.
