Definitions

  • the invention applies to the field of the firing of all types of weapons equipped with aiming systems, especially sights or viewfinders, without requiring the attention of specialists nor having to use firing ranges especially provided to do so.
  • a variant of this system is the alignment of the previously mentioned rods with the axis of the aiming point by means of a set of optical lenses.
  • this latter system is more accurate than the previous one, it also suffers from lack of accuracy, especially in not considering the firing distance. In addition it requires specialist equipment and personnel, something which is normally not generally within the reach of all users.
  • US 5 365 669 shows a laser boresight integrated in a cartridge-shaped housing, specifically adapted for each particular type of gun.
  • the apparatus for correcting the position of a sight, or viewfinder with respect to the axis of the bore of the weapon consists of a basic tube of the appropriate calibre for being inserted into the housing of the bolt of the weapon, which tube has, at its front end, a threaded inner region for coupling a second piece, which is also cylindrical and terminated in a frustoconical region divided into sectors of decreasing diameter, this second piece being pierced along its axis with an orifice of narrow diameter, of the order of 2 to 5 millimetres.
  • the various sectors of the frustoconical piece have diameters equal to the bases of the cartridges of the bullets of the various calibres of weapons.
  • At least the last of the sectors, the one of smallest diameter, can be removed from the rest of the frustoconical piece.
  • the cartridge, being empty, allows the laser beam to pass through, due to which it achieves the same effects, of guiding the beam and of precise coupling to the front part of the breech, as the last smallest-diameter sector, which has been separated.
  • a third piece which includes a system for emitting a laser beam, is also coupled further inside the tube.
  • this device has available its own power supply source and a switch situated in the final base of the basic tube.
  • On this tube is situated another piece, so that it can slide, formed by a sleeve of internal diameter equal to the outside of the tube, with an outer, rear butt heel, a butt flange also being provided at the extreme end of the basic tube so that the sliding sleeve cannot come off over this end, or over the front end, since the conical region of the frustoconical piece has a base which is slightly larger than the cylindrical region so as to form a stepped butt piece.
  • the power supplies and/or the switch can be arranged separately from the emitter.
  • the laser emitter can also be inserted either through the muzzle of the weapon or through the breech thereof.
  • the power supply and/or the switch could be arranged separately from the said laser emitter.
  • a variant of the present invention provides for the emitter to be remotely activatable, either by means of wires, or by magnetic or wave means or the like.
  • the parameters inherent in the laser beam emitted can be input as data into the guidance program of the weapon in order to fire it.
  • a further piece having a stepped surface of various diameters, with a flange at its large base, and pierced along its axis, with an orifice of the same diameter as the one of the frustoconical region of the apparatus.
  • This last piece is for matching to the muzzle of the weapon in question; to do that, its stepped surface allows it to be perfectly matched and centred on the basis of the calibre of the weapon.
  • the apparatus of the invention can be inserted into the housing of the bolt, once the latter has been removed, so that the frustoconical region of the end fits perfectly into the diameter of the breech in the region where the base of the cartridge sits when it is inserted into the breech, in such a way that the sliding sleeve fits perfectly within the receiver bridge through which the bolt is inserted, so that the axis of this apparatus coincides completely with that of the bore of the weapon, and at the same time coincides with the piercing of the piece which is coupled to the muzzle, so that, when the switch of the laser beam emission system is actuated, the laser beam will come out physically representing the abovementioned bore and producing a spot of light on a surface onto which it is aimed.
  • This spot of light will be the reference point for adjusting and correcting the deviation which exists with respect thereto on sighting through the sight or viewfinder, comparing the centre of the cross-hairs with the spot of light which physically represents the impact in the case or firing.
  • the apparatus for correcting the position of a sight or viewfinder with respect to the axis of the bore of the weapon consists of a cylindrical tube (1) of diameter appropriate for being inserted into the weapon, in place of the bolt, which is hollow and equipped internally with threadings at the front and rear regions, of sufficient size for screwing at least two pieces thereto.
  • the first piece which is coupled to this thread is one of cylindrical shape, frustoconical to its rear, divided into sectors of decreasing diameter (4).
  • the diameters of the various sectors which form this piece are equal to the calibres of various weapons.
  • the frustoconical piece is pierced throughout its length, internally, by an axial duct (a) of narrow diameter (2-5 mm). This axial duct is designed to allow a laser beam to pass through, emitted by a system present in another internal piece (7), which is also threaded at the same region as the frustoconical end.
  • the laser beam emitter system consisting of a 655 nm, 1 mW diode, with an achromatic lens, is included in the piece (7) coupled to its corresponding power supply, preferably in the form of 1.5 V batteries (6) and to a switch (2) screwed to the back end of the basic tube. While the apparatus is being mounted, the laser emitter is aligned, by means of small lateral orifices arranged on the basic tube, with the axial duct of the frustoconical piece. In this way it is possible for the laser beam to exit through the muzzle, coinciding with the axis of the bore of the barrel of the weapon.
  • a sleeve (3) which can slide with slight friction, whose outer diameter coincides with the internal diameter of the receiver bridge which houses the bolt so that, once the apparatus is inserted, in place of the bolt, making this sleeve move forward completely immobilizes the apparatus with respect to the weapon.
  • another piece (8) will be provided, whose external shape is stepped into various consecutive cylindrical sectors, and which is also pierced internally with the same orifice as that existing in the frustoconical piece, and fitted with a flange which limits its insertion into the corresponding muzzle, depending on its calibre, being exactly centred and therefore coincident with the axis of the piercing in the conical piece, with no possibility of being inclined due to the stepping of its surface into consecutive cylinders.
  • the internal piercing thereof also coincides with the said bore axis, so that, on actuating the switch (2) of the laser beam emitter system, the latter will physically represent the bore axis and, being projected on a flat surface, a spot of light will be produced which corresponds to the impact in the ease of firing, assuming that the bullet does not suffer a drop at this distance.
  • the mechanisms of the sight or viewfinder will be actuated to make the cross-hair point of the sight coincide with the spot of light projected through the bore axis of the weapon. It is not necessary to immobilize the weapon to carry out this operation.
  • targets provided for various distances can be used, since parallax is not the same for short and long distances.
