Abstract

At the front end of the barrel (28) of a weapon, a shot signal emitter (14) for emitting a shot signal which is dependent on a triggering signal is fitted by means of an adaptor (20). The adapter (20) and the housing (18) of the shot signal emitter (14) are designed to allow the distance (A) between the optical firing axis (16) of the shot signal emitter (14) and the sighting axis (24) of the weapon to be modified. Thus, the distance (A) between the sighting axis (24) and the optical firing axis (16) of the shot signal emitter (14) is kept to a minimum, even for different weapons.

Description

Unlocking device for simulated firing

Technical subject

The invention relates to a device for converting a weapon for simulated shooting according to the preamble of claim 1.

State of the art

A device of the type mentioned is known, for example, from US-A-3 938 262. The device contains a training cartridge which can be inserted into the weapon and which emits a trigger signal in the form of an explosion wave or a light beam when a firing pin is struck. Furthermore, there is a shot signal transmitter which can be attached to the front end of the barrel of the weapon by means of an adapter and which is used to emit a shot signal as a function of the trigger signal. In this device, it is disadvantageous that the optical shot axis of the shot signal transmitter is arranged coaxially with the axis of the barrel, which results in a large distance from the sighting axis of the weapon. This weapon can therefore only be used to shoot precisely at a very specific distance from the target, specifically when the sighting axis and the optical shot axis of the shot signal transmitter converge and intersect. At a shorter distance, the laser beam hits too low, i.e. the shot signal. At a greater distance, the hit situation is too high. The distance-dependent vertical offset can therefore be negative or positive. The distance between the sighting axis and the optical shot axis of the shot signal transmitter results in a Misjudgment if the gun is not held by the shooter in such a way that the optical shot axis and the sight axis are exactly vertically above one another. In addition, the axis offset and the angle between the barrel axis and the sighting axis are different for different weapons, so that the use of the shot signal transmitter for different weapons leads to different results.

Presentation of the invention

The object of the invention is to design a device of the type mentioned in such a way that, on the one hand, the distance between the optical shot axis of the shot signal transmitter and the sighting axis is kept as small as possible, and on the other hand, when using the shot signal transmitter, it can be kept essentially the same for different weapons.

The object is achieved according to the invention by the characterizing features of claim 1. Because the distance between the optical shot axis of the shot signal transmitter and the sighting axis of the weapon can be changed in the shot signal transmitter with the aid of the adapter, this distance can be as small as possible when using the shot signal transmitter on different weapons be held or even zero. The distance can be adjusted in steps or continuously. On the one hand, this reduces the error rate when firing at targets of different distances and when the weapon is not recognized. In addition, this error rate can be kept practically the same for different weapons. This significantly improves the hit rate in simulated shooting, and errors that arise can be compensated or taken into account in a simpler manner on the one hand by the shooter and on the other hand by the target device or any evaluation device.

Advantageous embodiments of the device are described in claims 2 to 15. A particularly simple solution describes claim 2, since a pipe socket of the shot signal transmitter to be inserted into the barrel of a weapon, depending on the weapon, is to be inserted into a corresponding entry opening of the shot signal transmitter, which enables the smallest distance between the optical shot axis of the shot signal transmitter and the sighting axis. Unused entry openings in the housing of the shot signal transmitter can be closed gas-tight, for example, by means of a simple screw.

For weapons with a larger axis offset between the sighting axis and the barrel axis, an embodiment of the device according to claim 3 is particularly advantageous since the housing of the shot signal transmitter can then be kept smaller than would be necessary for an existing axis offset between the sighting axis and the barrel axis. For trigger signals propagating at the speed of sound in the barrel, an embodiment according to claim 2 or 4 is advantageous.

A design of the shot signal transmitter according to claim 5 is particularly expedient since the distance between the shot axis and the sighting axis can then be kept particularly small, the development according to claim 6 reducing the distance to zero and the design according to claim 7 practically zero.

The design of the device according to claim 8 enables a further fine-tuning of the shot signal transmitter on the one hand with regard to the basic tuning and on the other hand also with regard to the adjustment to a corresponding weapon. There are various possibilities for the formation of the actuating device. Claim 9 describes a particularly simple design of the actuating device with regard to the construction and handling, the fine-tuning being further improved by the design according to claim 10. Various spring devices can be used to pretension the light transmitter insert in the housing and the dome against the actuators; claim 11 describes a particularly simple embodiment.

A further development of the device according to claim 12 is particularly advantageous, as a result of which it can be ensured that a hit on a target device is only evaluated if a shot on the weapon is determined on the target device and / or evaluation device. For this purpose, it is particularly advantageous if the shot detector is designed according to claim 13.

The trigger signal that arises when the trigger is triggered can be very different, for example an optical, electrical or mechanical trigger signal. Suitable sensors for this are light or laser sensors, electrical switches; for pressure waves, they are dummy cartridges, sound transmitters or the like. However, it is particularly preferred to trigger a shot signal generator which generates a trigger signal which propagates at the speed of sound in air in the barrel of the weapon and which is generated when the firing pin strikes a practice cartridge. The transmission of the shot signal at the shot signal transmitter then corresponds to the actual behavior of the weapon when firing a normal shot. Regardless of the length of the barrel, the runtime of the trigger signal corresponds approximately to the runtime of a bullet through the barrel, so that the shot signal is sent to the shot signal transmitter at about the same time as the bullet when firing with live ammunition would leave the gun. Every movement of the weapon caused by the shooter during the barrel of a bullet in the barrel of the weapon, such as the so-called ripping of the weapon, is also taken into account realistically in simulated shooting. There are various options for the design of the exercise cartridge. The trigger signal can be generated in a variety of ways, for example by an acoustic signal generator in the training cartridge. A particularly simple embodiment of the exercise cartridge is described in claim 14, the further development in accordance with claim 15 being particularly preferred.

Ways of Carrying Out the Invention

FIG. 1 shows a system for simulated firing with a weapon 2 at a target device 4, which is connected to an evaluation device 6 for displaying the hits. A pistol is used here as a weapon, which is provided with a device for simulated shooting. The device contains a training cartridge 8, which is arranged in the barrel and / or cartridge chamber of the weapon. If a trigger is fired at a trigger 10 of the weapon, a firing pin 12 strikes the practice cartridge 8 and triggers a trigger signal, which preferably continues in air along the barrel at the speed of sound and is received by a shot signal transmitter 14 and along to trigger a shot signal the optical shot axis 16 is used.

The shot signal transmitter has a housing 18 on which an adapter 20 for attaching the shot signal transmitter 14 to the weapon 2 is arranged. For this purpose, the housing contains various entry openings 22, 22a, 22b, 22c, one above the other, into which the adapter can be inserted in order to set the distance A between a sighting axis 24 of the weapon and the optical firing axis 16 of the shot signal transmitter 14, that is, to keep it as small as possible can. In the present example, the adapter 20 is designed as a pipe socket 26 which is inserted coaxially into the barrel 28 of the weapon 2, specifically in such a way that the barrel axis 30 and the optical shot axis 16 of the shot signal transmitter coincide. Sealing rings 32 serve on the one hand to hold and center the pipe socket 26 in the barrel 28 and on the other hand to provide a gas-tight seal. Furthermore, the sealing rings prevent metallic contact between the barrel of the weapon and the pipe socket, causing damage to the barrel and the transmission of disturbing structure-borne noise from the barrel to the adapter and thus also to the shot signal transmitter is prevented.

The shot signal transmitter 14 is equipped with a shot detector 34, which has a transmitter 36 arranged on the top or, as shown, on the underside of the housing 18, which cooperates with a slave 38 arranged underneath, which is connected to a control part 40 of the target device 4 . The transmitter 36, which preferably operates in the infrared wavelength range, generates a signal each time a shot signal is sent out at the shot signal transmitter 14. The control part 40 only signals a hit on the evaluation device 6 when the receiver 38 receives a shot cancellation signal and practically at the same time the target device 4 receives a shot signal. This ensures that hits that are generated by a third-party shooter at the target device 4 are not evaluated at the target device 4 or evaluation device 6, because the third-party shooter cannot generate a shot-off signal at the receiver 38. This is achieved, for example, by the shot cancellation signal generated by the shot detector either being relatively narrow, e.g. is bundled in a cone of 14 ° in order not to trigger an adjacent taker even in different shooting positions (standing, lying, kneeling) and / or has a certain property, for example frequency, that differs from the shot detector of the neighboring shooting range.

Figures 2 and 3 show details of the shot signal generator 14. This contains as a light transmitter a laser insert 42 from a laser diode 44, which preferably works in the infrared range, and a collimator 46 to generate a parallel, limited beam path for the shot signal. The laser insert has a support ring 48 with a spherically shaped support surface 50, which is supported on a correspondingly shaped counter ring 52 in the housing, so that the laser insert 42 is held pivotably. A spring 54 serves to bias the laser insert 42 against the counter ring 52 Laser insert 42 is also equipped with an adjusting device 56 in order to be able to adjust laser insert 42 with respect to its optical firing axis 16. The adjusting device has a cylindrical mandrel 58 arranged rearward on the laser insert 42, which cooperates with two actuators 60, 62, the axes 64, 66 of which are aligned perpendicular to the mandrel axis 68. Each actuator 60, 62 consists of a conical part 70 which interacts with the mandrel 58. The tapered end of the conical part 70 is closed by a head part 72, which preferably serves as a guide for the actuator in order to compensate for any thread tolerances. The thickened end of the conical part 70 merges into a threaded part 74, by means of which each actuator 60, 62 is arranged in a threaded bore 76 of the housing 18. By screwing the actuators 60, 62, the points of engagement of the mandrel 58 slide along the conical parts 70 of the actuators, as a result of which the mandrel axis 68 and thus the optical firing axis 16 can be changed and adjusted accordingly horizontally and / or vertically. The lateral surfaces of the conical parts 70 which interact with the mandrel 58 are oriented at an angle of 90 ° to one another. Due to the conical design with the cone angle 2α, a reduction in the screwing movement and thus an improved fine adjustment is achieved. A cone angle 2 of approximately 23 ° already gives a five-fold reduction. A spring 78 ensures the secure contact of the mandrel 58 against the conical parts 70 of the actuators 60, 62. The springs 54, 78 which serve to pretension the laser insert 42 and the mandrel 58 are formed by corresponding arms of a leaf spring 80 which is fastened in the housing 18 by means of a screw 82. The housing also contains a circuit board 84 which contains the electrical and electronic components for operating the shot signal transmitter 14, which are not shown in more detail, including a pressure sensor which responds to the trigger signal of the training cartridge. FIG. 2 also shows the transmitter 36 of the shot detector 34. FIGS. 4 and 5 show the arrangement of the shot signal transmitter 14 by means of an adapter 20a designed as a holder 86. The holder contains an arm 88 which can be fastened to the outside of the barrel 28a of a weapon by means of a clamping ring 90 and a clamping screw 92. A second arm 96, which is arranged essentially at right angles to the first arm 88, projects vertically upward and contains a stop surface 98 for attaching the shot signal transmitter 14. A screw 100 is screwed into an opening 102 in the arm 96 into the entry opening 22a of the shot signal transmitter and holds it firmly on the arm. A lower entry opening 22c of the shot signal transmitter communicates with a channel 104 in the arm 96, into which a waveguide 106 is inserted. The waveguide is designed as a hose and its part facing away from the arm 96 is inserted into the barrel 28a in order to transmit the trigger signal which occurs when the shot is triggered into the shot signal generator 14. In this embodiment of the adapter 20a, the relatively large axis offset V between the barrel axis 30a and the sighting axis 24a is reduced to the small distance A of the optical firing axis 16 from the sighting axis 24a.

A preferred practice cartridge 8 is shown in FIG. It contains a cylindrical sleeve 110 with a front through opening 112 for the exit of a trigger signal. A piston 114 is slidably disposed in the sleeve 110. The piston is preferably made of plastic, such as a polyacetal plastic sold under the "Delrin" brand. A spring 116 biases the piston 114 against a rear stop 118 of the sleeve 110. In order to absorb the blow of an ignition pin, an impact part 120 is present in the piston 114, which can also be made of plastic, possibly the same plastic as the piston, or of another material, preferably metal. When the firing pin strikes the striking part, the piston 114 is jerkily moved forward against the force of the spring 116 and thereby generates a trigger signal in the form of a pressure wave which passes through the through opening 112. occurs and continues along the run at the speed of sound in air to the shot signal generator 14. This configuration has the great advantage that the running time of the trigger signal corresponds approximately to the running time of a bullet through the barrel, so that the exit of the shot signal at the shot signal transmitter coincides with the exit of the bullet from the barrel, as a result of which any movement of the weapon caused by the shooter is taken into account, which is given between the firing of the shot and the exit of the projectile from the weapon. The practice cartridge has the further advantage that it has an extremely simple structure, since it does not require any electronic components. Triggering the shot signal transmitter via such a trigger signal has the further advantage that the weapon actually only responds to the triggering of the shot, that is to say the trigger signal, and not to any other blows triggered, for example, by reloading, releasing or leaning the weapon against an object . The device for simulated shooting or the weapon equipped with this device is thus insensitive to external influences.

FIG. 7 shows a further shot signal transmitter 14a, in which the light transmitter insert, which is designed as a laser insert 42a, is arranged vertically. The optical shot signal emerging along the optical axis 122 is deflected into the optical shot axis 123 by means of the deflection device 124 located in the sight axis 24b, which is designed as a semi-transparent mirror 126, preferably inclined at 45 °, so that it coincides with the sight axis 24b. There is an optimal aim regardless of the distance of the target and jamming errors are excluded.

FIG. 8 shows a further shot signal transmitter 14b, the light transmitter insert 42b of which is also oriented vertically. The light transmitter insert 42b contains, as a deflection device 124a, one in the optical axis 122a of the light transmitter insert. zes arranged glass rod 128, which has at the upper end a preferably deflected and mirrored deflection surface 130 at 45 °. The glass rod 128 ends directly under the sighting axis 24b, so that the shot signal emerging via the glass rod 128 along the optical axis 122a is deflected at the deflection surface 130 into the firing axis 123a practically parallel to the sighting axis 24b and is only a very small distance from it .

FIG. 9 shows a further adjusting device 56a for the mandrel 58 of a light transmitter insert. The actuators 60a, 62a contain actuating heads 132, 134 at the front ends, which are aligned perpendicular to the actuator axes 64a, 66a and form an angle of 90 ° with one another. By screwing the actuators in and out, the mandrel can be adjusted in the horizontal and vertical directions, a spring 78a presses the mandrel 58 against the actuating heads 132, 134.

The principle described for changing the distance between the sighting axis and the optical firing axis of the shot signal transmitter is not limited to the described and particularly preferred transmission of a trigger signal which propagates at the speed of sound in air when the weapon is pulled, but is also suitable for other known trigger systems, for example for explosion signals and optical signals as described for example in US-A-3 938 262 or EP-B-0 467 090 or the like. Electrical signals are also possible, for example by actuating a trigger by means of the trigger, which triggers a current surge which triggers the shot signal generator via a line leading along the barrel to the shot signal generator.
