Definitions

  • the invention relates to a laser pulse transmitter for a weapon according to the preamble of claim 1.
  • a laser pulse transmitter of the type mentioned is known from US Pat. No. 3,938,262.
  • a piezoelectric converter serves as a switch for triggering the laser pulse transmitter and as a current source. This results in the disadvantages that the converter must be relatively large for an adequate power supply and, on the other hand, considerable impact is required.
  • the large design limits the laser pulse transmitter to weapons of large caliber. The high impact can also damage the pulse transmitter and / or the firing pin and thus the weapon.
  • the object of the invention is to design a laser pulse transmitter so that the disadvantages mentioned are avoided.
  • the piezoelectric transducer Since the piezoelectric transducer is only used as a switch, very small current surges are sufficient to trigger the circuit and thus to send out the laser signal.
  • the converter can therefore be kept very small and the impact force of the firing pin reduced or damped accordingly. This in turn leads to protection of the laser pulse transmitter and the weapon. Due to the small design, it can also be used in small-caliber weapons.
  • the circuit and its arrangement can be designed in various forms and arranged in a sleeve. A very useful solution is described in claim 4, since then no additional mechanical holding devices are required, but the printed circuit board is held in the cylinder of the sleeve. If necessary, batteries can also be arranged on both sides of the printed circuit board.
  • the laser collimator can be arranged according to claim 9 at the front end of the insert, this being possible only for weapons of a certain caliber.
  • the training according to claim 10 is particularly suitable.
  • the laser pulse transmitter insert can be designed for a wide variety of weapons, i.e. have the shape of the required cartridge.
  • the laser pulse transmitter shown in FIGS. 1 to 3 has an insert housing in the form of the cartridge of a weapon, which contains a sleeve 2 with a front holder 4 and a rear holder 6.
  • the rear holder 6 is formed in one piece with the sleeve 2 and serves to receive a switch 8 of the laser pulse transmitter.
  • This contains a piezoelectric transducer, preferably a piezoceramic 10 and is mounted in a recess 12 in the holder 6.
  • the piezoceramic 10 is arranged between two metal plates 14 and 16, each having a conductor 18 and 20 of the piezoceramic.
  • the outer metal plate 16 is preferably made of hardened steel in order to prevent damage to the piezoceramic 10 by the firing pin of a weapon.
  • An outer plate 22 serves to secure the arrangement in the rear holder 6 of the sleeve.
  • the front holder 4 is removably arranged on the sleeve 2 and secured by means of a stud 24. At the front end of the holder 4, this carries a laser collimator in a recess 26.
  • the lines 30 used to connect the laser collimator 28 run through the holder 4.
  • a chamber 32 is formed, in which a printed circuit board 34 is arranged, the width of which corresponds to the inner diameter of the sleeve 2 and the length of which corresponds to the length of the chamber 32.
  • a power source 36 consisting of two batteries is arranged on one side of the printed circuit board 34 and a driver circuit 38 for the laser collimator 28 on the opposite side.
  • the driver circuit is designed such that it generates a shot pulse of 10 microseconds, for example. With the laser pulse transmitter shown, more than a million shots can be fired.
  • a corresponding modulator 50 is indicated by dashed lines in the circuit according to FIG. 4.
  • FIG. 5 shows a further advantageous switch 52 for the laser pulse transmitter.
  • the switch contains a switch housing 54 made of plastic, which can be inserted into a recess of the holder 6 of the sleeve 2 and into which a pot-shaped cover 56 made of plastic is inserted, which has a central opening 58 for receiving a steel ball 60, onto which the firing pin of the weapon is fired the same strikes.
  • the steel ball 60 is supported on the inside on a preferably prestressed elastic ring 62, which rests on a steel plate 64, under which a piezoceramic 66 is arranged, which is supported on the inside on a further plate 68.
  • FIG. 6 shows a further laser pulse transmitter which contains the switch 52 shown in FIG. 5 on one side of the housing.
  • the housing 78 in turn forms a chamber 80 in which a printed circuit board 82 with a driver circuit and a battery analogous to the example in FIG. 1 are arranged after the switch 52.
  • the printed circuit board 82 occupies only a portion of the chamber 80, a laser collimator 84 connecting to the printed circuit board 82 against the front end of the housing.
  • the front end of the housing 78 is formed by a centering insert 86 which can be inserted into the barrel of a weapon and is used to center the laser pulse transmitter.
  • the centering insert 86 contains a pinhole 88 at the front end to align the laser beam with the axis of the weapon.
