Definitions

  • the invention relates to a method for aligning a firearm barrel axis with respect to a target line of a corresponding target device by visual representation of the barrel axis and a device therefor.
  • Known optical instruments for aligning a rifle barrel axis or the like To a target line of an aiming device used generally work by projecting the barrel axis to an auxiliary point at which the coincidence of the target line and barrel axis is checked.
  • This method requires an optical device in the form of an escape telescope, which is usually pushed into the barrel of the rifle via a guide rod and which allows the observation of a target point from a certain minimum distance between the rifle and the auxiliary point.
  • DE-OS 33 19 110 shows a special embodiment of a caliber rod serving as a guide rod.
  • the inventor set himself the task of a method and to develop a device of the type mentioned above, with the aid of which it no longer needs an auxiliary point.
  • the alignment and checking are to be simplified, in particular changes in the position of parts of the optical device should not impair the accuracy.
  • a method of the above-mentioned type leads to the solution of this task, in which the barrel axis reflects into the target device and is compared there with the target line.
  • the finish line normally runs parallel to the barrel axis in the basic setting of the target device, it is provided within the scope of the invention that the optical representation of the barrel axis outside the barrel is reflected back exactly into the target device parallel to the barrel axis. However, it is left to the respective requirements to take into account a non-parallel arrangement of the target device by means of appropriate optical measures.
  • a reflector is used for reflecting, wherein a triple prism, which is arranged approximately at right angles to the running axis, is suitable for reflecting parallel to the running axis.
  • a device according to the invention designed as an optical instrument R according to FIG. 2, serves to check a barrel or tube core axis 1 of a barrel L, indicated only by dash-dotted lines, and a target line 2 of a target device Z.
  • the optical instrument R is composed of a housing part 3 for accommodating a triple prism 7 and a housing part 4 for accommodating in particular a collimator 6 and, in the position of use, engages in the barrel L with a caliber rod 5.
  • the collimator 6 there is a cross hair 9 illuminated by a lamp or cold light source 8 in such a way that a lens 10 provides an image thereof from infinity can jject.
  • the collimator 6 can be tilted from its position parallel to the running axis 1 by means of adjusting screws 11.
  • the housing part 3 is inserted into the housing part 4 with a tube piece 13, the mounting being carried out by a spring-loaded detent ball 12.
  • the housing 3 forms a chamber 14 for receiving the triple prism 7, a chamber axis 15 running approximately perpendicular to the barrel axis 1.
  • the chamber 14 has an opening 16 through which the target line 2 runs, which on the other hand penetrates the target device Z.
  • the latter is formed from known required elements, namely objective 17, reticle 18 and eyepiece 19.
  • this optical instrument R is very simple.
  • the barrel axis 1 is projected over an infinity image of the cross hair 9 and made visible via the triple prism 7 as a parallel reflection to the target device Z.
  • This parallel reflection of the running axis 1 can then be compared with the target line 2.
  • the special peculiarity of the triple prism 7 according to FIG. 1 is to always reflect an incident beam S parallel to the incident beam S irrespective of the relative position of the incident beam S and triple prism 7. If, for example in FIG. 1, the triple prism 7 is tilted into position 7 1 , the incidence beam S is offset, but is still reflected exactly in parallel.
  • the chamber 14 of the triple prism 7 can be rotated around the running axis 1 by several angular degrees to the right or left without a loss of accuracy being associated therewith. If a limit angle is exceeded, only the image is cropped. That depends on the exact parallel reflection of the running axis 1 neither from the exact position nor the angular position of the triple prism 7, but only from the intrinsic accuracy of the triple prism 7 itself. This eliminates not only the adjustment effort when mounting the triple prism 7 relative to the collimator 6, but the instrument R is also insensitive to impacts etc. during use.
  • the possibility is opened to check any rods / collimator errors.
  • the rod / collimator unit is rotated in the axis 1 with respect to the triple prism 7. Escape errors appear to the observer on the reticle 18 in the telescopic sight Z as circular movements.
  • the collimator 6 can now be tilted so far via the adjusting screws 11 according to FIG. 3 that deviations due to, for example, curved rod 5 can be eliminated.
  • the tube piece 13 of the housing part 3 was provided with a 90 degree grid 20 according to FIG. 4, which enables the x / y correction axes according to FIG. 3 to be identified easily .
  • the entire device according to the invention is designed so simply that errors or deviations can be registered and eliminated immediately. At the same time, the device offers a maximum of accuracy.
  • FIG. 6 shows a further embodiment of the present device, which largely resembles the device according to FIG. 2.
  • the caliber rod 5 has a diameter which is smaller than the clear diameter of the barrel L.
  • Such a caliber rod 5 is provided with thickenings 21 and 22, the outer diameter of which corresponds to the inner diameter of the barrel L. In this Way you reach. that the caliber rod 5 rests in the barrel L without play. This is very important because the triple prism 7 and the other components of the present device, which adjoin the outer end of the caliber rod 5, have a considerable weight and thus exert a tilting moment on the caliber rod 5. Under the influence of the weight mentioned, the device would tip over the edge 23 of the barrel mouth, so that the end of the thin caliber rod 5 in the barrel would move upward.
  • the axis of the caliber rod 5 would not coincide with the axis of this barrel section, so that the axis 2 of the telescopic sight Z could not be brought into line with the axis 1 of this barrel section. If the caliber rod 5 is used with the mentioned thickenings 21 and 22, then it should be clear that such a device is not universally usable, but that it can only be used with weapons of a given caliber.
  • Fig. 6 shows an embodiment of the present device, which can be used practically regardless of the diameter of the opening in the barrel L.
  • This device also uses a smooth, cylindrical caliber rod 5, the diameter of which is smaller than the diameter of the barrel L of the smallest caliber in question.
  • the part of the device connected to the caliber rod 5 has a weight which would cause the device to tilt around the barrel mouth edge 23 given the diameter of the caliber rod 5.
  • the caliber rod 5 can be provided with a counterweight 25.
  • the size of this counterweight 25 is selected so that the entire caliber rod 5 rests securely on the bottom of the barrel interior. This state can be clearly seen from FIG. 6, a gap 24 of practically constant width being present between the upper side of the caliber rod 5 and the upper part of the barrel L.
  • the counterweight 25 can be designed as an inseparable part of the caliber rod 5 (not shown), which is made of a material with a high specific weight than that of the rest of the caliber rod 5.
  • the caliber rod 5 is advantageously made of a rigid material, such as made of tungsten carbide, aluminum oxide or a ceramic material. Lead or the like could be used for the counterweight 25, but this entails certain restrictions. It would be more advantageous to make the counterweight as a rod 26 from a material which is heavier than the material of the caliber rod 5 and which at the same time has a better rigidity than lead. The size of the required counterweight could then be adjusted by a suitable choice of the length of this rod. So that any falsifications of the position of the caliber rod 5 are eliminated, the diameter of the counterweight rod 26 is smaller than that of the caliber rod 5.
  • the caliber rod 5 could, under certain circumstances, have a considerable length, which could prove disadvantageous, for example, when transporting such a device.
  • the counterweight rod 26 can be designed to be insertable into the caliber rod 5.
  • the end part of the caliber rod 5 lying inside the barrel is provided on the end face with a bore 27 in which the counterweight rod 26 is inserted. 6, the bore 27 and the insertable part of the counterweight rod 26 are provided with corresponding threads 28.
  • Another problem relates to the fact that the first housing part 3, which contains the triple prism 7, is running L loose-fitting caliber rod 5 tends to rotate about the axis of the caliber rod 5, so that it is not readily possible to hold the outlet opening 16 of the first housing part 3 relative to the riflescope Z, which is attached to the breech housing 29 of the firearm. 7 to 9 show a measure which ensures the position of said outlet opening 16 with respect to the target device Z. From Fig.
  • the caliber rod 5 is inserted in the second housing part 4, in such a way that the axis of the caliber rod 5, the diameter of which in the present case corresponds to the inner diameter of the barrel L, and the axis of the housed in the second housing part Align collimators 6 with one another.
  • the crosshair 9 in the collimator 6 is provided with a division 37 which can be seen from FIGS. 12 and 13.
  • the zero point or center point 39 of the cross hair 9 lies on the axis 1 of the collimator 6 and the caliber rod 5.
  • the collimator 6 is arranged such that it is connected upstream of the barrel mouth 23.
  • a slip clutch 30 in which the caliber rod 5 and thus also the collimator 6 connected to it can only be rotated while overcoming a certain resistance.
  • This resistance can be set by springs 31, which are located between the body 32 of the slip clutch 30 and the caliber rod 5.
  • the outer surface of the body 32 of the slip clutch 30 is adapted to the shape of the barrel mouth so that the body 32 can sit non-rotatably in the barrel mouth.
  • the running end is provided with a fire flash eliminator 33 with a conical inner surface
  • the outer surface of the coupling body 32 is accordingly conical. If the eliminator 33 has slots 34 running in the axial direction, then the outside of the slip clutch body 32 can be provided with a protruding cam 35 which is in one the slots 34 can snap.
  • the device just described can only be used with firearms of a certain type.
  • 10 and 11 show a further embodiment of the present device, which can be used universally and which is also secured both against tipping over the edge 23 of the barrel mouth, which is only shown schematically here, and about the axis 1 of the caliber rod 5 or the run L.
  • This last-mentioned rotary movement is indicated in FIG. 10 by means of the arrow M.
  • the pipe section 13 of the first housing part 3 is provided with a tubular extension piece 40 which at least partially surrounds the second housing part 4. That end part of the second housing part 4 to which the caliber rod 5 is connected is provided with an actuating element 41, the diameter of which is larger than that of the extension piece 40 and the peripheral part of which is roughened, for example by knurling.
  • An elongated weight piece 45 adjoins the underside of the extension piece 40, specifically in the region of that end part of the extension piece 40 to which the caliber rod 5 is connected. The longitudinal axis of the weight piece 45 runs obliquely downward with respect to the axis of the caliber rod 5 and specifically in the direction towards the cartridge system of the firearm.
  • the weight piece 45 connected to the other parts of the present device in this way has the effect that the center of gravity W of the device shifts into an area which lies below the barrel L and thus behind the barrel mouth 23.
  • the distance H between the mouth edge 23 and the center of gravity W of the device represents the lever arm, at the end of which a force acts. This force results from the weight of the device and acting in the center of gravity W. it strives to rotate the device counterclockwise. The consequence of this is that the caliber rod 5 rests on the bottom of the barrel L, as explained in connection with FIG. 6.
  • the weight piece 45 is advantageously hollow and, moreover, is designed such that it serves to hold batteries that are required to feed the light source 8 in the collimator 6.
  • the weight piece 45 has a lower section 46, in which the 8 arteries (not shown) can be arranged one behind the other.
  • this piece 45 has an upper section 47 which forms one unit with the extension piece 40 and at the other end of which the lower part 46 can be connected.
  • FIGS. 12 and 13 the cross hair 9 together with the division 37 and a target mark 38 are shown, which is attached to the reticle 18.
  • the target line 2 passes through the tip of the target mark 38.
  • This target mark 38 corresponds essentially to the grain of an ordinary, mechanical target device.
  • the caliber rod 5 After the caliber rod 5 has been inserted into the barrel mouth, one must first check the setting of the device itself. This is done by looking into the target device Z and keeping the current position of the target 38 in relation to the crosshair 9. This is projected into the target device Z using the triple prism 7. Now one turns the collimator 6 together with the caliber rod 5 in the course L by 180 degrees and checks whether the position of the target mark 38 in the field of view of the aiming device or telescopic sight Z has changed or not. If the position of the target 38 has changed, the position must be changed using the screws 11 (FIG.
  • FIG. 13 shows another case of the position of the target mark 38 with respect to the center 39 of the cross hair 9.
  • the imaginary finish line 2 stands at the target mark 38 on the left leg of the crosshair 9. From this one can see, among other things, how large the difference between the position of the finish line 2 and the position of the barrel axis 1 is. Because the distance between the lines of the division 37 on the crosshairs 9 is known and from this the size of the difference mentioned can be calculated.
  • the caliber rod 5 extends through the entire barrel.
  • the length of the caliber rod 5 is advantageous such that it extends only in the first quarter of barrel L from mouth 23 of the same. If the collimator 6, which is coaxial with it, connects to such a short caliber 5, then the axis 1 of the light beam generated by the collimator 6 lies exactly in the axis of the trajectory of the projectile. With the help of the present device, therefore, the target line 2 can be brought into exact agreement with the axis 1 of the projectile trajectory. You don't need to fire a single shot.
