Optoelectronic shooting training method 6 8 7 2 6

The invention relates to a method for practicing the shooting of handguns, such as pistols and rifles, based on an optoelectronic transceiver device which can be attached to conventional weapons and a target which differs from its environment by the reflection and / or scattering property of different optical radiation.

In the practice of shooting, especially sports shooting, the so-called the importance of dry training is very great. The importance of dry training, i.e. training with a gun without the actual firing, is further emphasized by the fact that it is possible to practice it safely, e.g. in ordinary rooms. The problem today is mainly how to get shooters motivated to perform adequate and careful aiming and firing training without cartridges. Another problem is that there are no known effective methods for the immediate control of the result of dry training, except in Finnish patent application no. 831183.

Em. however, the method described in the patent application is intended mainly as a versatile shooting analysis method for training shooters, whereby one important use of the device based on it is use in a real shooting situation. In the Finnish patent application no. Perhaps the most important and valuable measurement information for the method described in 831183 is the continuous monitoring of the full-point point during aiming and firing. Implementing this idea in practice results in a rather expensive device that is usually not possible to acquire for personal ownership and use.

Previously known solutions for the use of light in connection with shooting practice have been mentioned e.g. in the above-mentioned Finnish patent application and in the Norwegian patent application no. 770997 (Utleg-ningsskrift nr. 144118). In summary, the main shortcomings of the known solutions are: the method or device is not suitable for use in ordinary weapons without special measures or not at all (e.g. separate laser weapons); the method is so versatile and complex that its practical implementation 2 68726 makes the device too expensive for the personal ownership and use of the shooter.

In the present invention, a simple transceiver device is attached to the weapon with which the training is to be performed. Thus, each shooter can practice, for example, in competitions with his weapon. Since the method according to the invention is limited to detecting whether a shot fired with an optical beam fell inside or outside a limited area of the desired size and shape, the table is simple. The delimitation of the optical panel takes place in such a way that the panel (or the panel and its surroundings) are formed by optically differently reflecting and / or scattering surfaces. In the simplest case, the optical panel is e.g. a circular reflective label on a conventional backing surface (e.g. a wall) and the transmitted optical beam is a light pulse of narrow divergence and diameter, whereby the size of the label practically alone determines the difficulty of hitting (i.e. the hit angle).

A separate target can be used as the actual target board - and is obviously effective for training as well. Thus, the target can be selected as closely as possible to the actual situation, and the difficulty of hitting can be adjusted by changing the size of the optical target. Thus, dry shooting training can be easily performed at varying shooting distances and still it is known what result the size of the optical board used would correspond to in a real situation.

One form of training used by shooters is to record shots that go outside a circle of a certain size. In this case, for example, the area corresponding to the hit values ten and nine is removed from the table, in which case only the worse results are registered. The corresponding dry training can be easily simulated with the device according to the present invention.

The invention described here is particularly well suited for the training of biathletes in shooting, because even in actual shooting, only hits are taken into account. In addition, implemented with the prior art, the operating distance of the device according to the invention ("firing distance") extends up to hundreds of meters, so that the firing distance 3 68726 can also be chosen as real.

At its simplest, hits or passes are indicated by an audible or visual signal. If you want to record and record hits / shots for a longer period of time, separate counters and display devices can be connected to the device. The detection of the firing moment can take place by means of a sensor attached to the trigger of the weapon or on the basis of an energy pulse caused by the fired weapon (in which case the sensor can be in the same housing as the transceiver device).

In order to provide the above features, the invention is mainly characterized by the features set forth in claim 1.

The invention will now be described in more detail by way of example with reference to the accompanying drawing, in which

Figure 1 shows a training apparatus applying the method.

Figure 1 shows a transceiver device 3 attached to an ordinary pistol 1 by means of a magnet and a guide spindle 2. In addition to the transmitter and receiver, the transceiver device includes e.g. the power supply (battery or accumulator), the operating switch, the collision warning device (sound or light signal), any counters and displays for counting the hits and, if any, the device if no external trigger sensor is used.

The transmitter consists of a semiconductor laser, optics and laser modulation electronics. The trigger moment of the weapon 1 is identified either by the energy pulse caused by the trigger of the tuned weapon or by a sensor connected to the trigger of the weapon. The laser transmitter transmits a short single light pulse only after a suitable adjustable delay so that the time of departure and detection of the light pulse corresponds approximately to the time of departure of the assumed bullet from the barrel of the weapon.

The receiver consists of a sensitive light detector (light emitting diode or transistor), the amplifier electronics it needs, and detector electronics that detect light pulses hitting the reflector.

Depending on the electronics of the receiver, the transmitter, the desired operating distance and the reflector film 6 used, the receiver also requires simple optics and an optical filter to improve the sensitivity.

In addition to the parts to be attached to the weapon, the apparatus includes a sighting board 5 and an optical board 6 for a laser beam. The transceiver device 3, the boards 5,6 and the weapon sights 7 are tuned so that when aiming at the target board 5, the narrow light beam emitted by the laser hits the board 6. The board 6 is made e.g. of a cheap reflective film with a reflection coefficient typically 100 ... times compared to conventional backing surfaces (wood, paper, concrete, etc.). Thus, the receiver can easily detect when the beam hits the reflector. By resizing the reflector, the difficulty of hitting can be easily adjusted.

The size and shape of the aiming board 5 is chosen so that the board looks similar to the actual training distance used when aiming. If the shooter does not want to move the position of the sights 7 of his weapon during the dry training, the necessary alignment adjustment can be performed by adjustable mounting of the transceiver device 3 and / or by changing the relative position of the boards 5,6.

It will be apparent to those skilled in the art that the various embodiments of the invention are not limited to the example set forth above, but may vary within the scope of the claims set forth below.
