Description

[Detailed description of the invention] The present invention relates particularly, but not exclusively, to devices for simulated shooting. Adapted for use with belt weapons to modify a gun, thereby making it easier to fire sometimes by emitting a beam of electromagnetic radiation that can be detected by a suitable target sensor. , which is about a device that does not use bullets but allows you to practice shooting with an actual gun. be. Devices of this type are referred to below as devices of the defined type.

The advantage of using a real gun is that you are rarely forced to use it in tense situations. It is possible to practice the use of guns that are only available at minimum cost and without danger. It is in being able to do.

Another use of the invention is to practice gun sports within a confined area. .

Background technology Devices of the defined type are described in British Patent Specification Nos. 1034026 and 1595.1. Known from No. 89.

British Patent Specification No. 1034026 describes a dummy cartridge housed in a chamber. , and this dummy cartridge fires the switch when its slidable contact member is struck by the firing pin. act as a channel and move outward from the chamber to form radiant energy emitters. contact with the barrel attachment. For this early configuration, the power source was external to the firearm. This not only detracts from the realistic simulated use of the firearm, but also This adds a troublesome electrical conductor between the two. British Patent No. 1595189 is , describes a conventional pistol that uses radiant energy emitters and The switch unit is inserted into the barrel and the power source is placed inside the pistol magazine. It is more suitable for simulated shooting. In this configuration, the magazine is equipped with an electrical conductor. Not only is this necessary, but the sense of reality of loading the cartridge into the chamber is lost.

Therefore, until now, it has been possible to: In order to provide a power source for radiation emitters that are small enough to be easily adapted to portable weapons. It is clear that there was a problem.

Disclosure of invention According to one aspect of the invention, we provide an apparatus adapted for inclusion in a portable weapon, This device is an electromagnetic radiation emitter adapted to emit radiation from the barrel of a gun. It consists of a body and a power supply for the radiator consisting of a capacitor, and the radiator is used to launch a portable weapon. It is designed to be activated when the gun is fired.

Therefore, as in the case of the above-mentioned prior art, there is no external part of the gun, such as the butt or the magazine. Instead of an internal battery, a suitable capacitor is housed inside the gun and this The capacitor is preferably recharged before being inserted into the gun, yet also suitable for portable use. It can be conveniently charged from a battery pack.

Low-loss electrolytic capacitors hold charge for hours without significant loss. has been found to be suitable for this purpose, but other suitable types of Capacitors can also be used. This capacitor is suitable for both guns and pistols. Whether it's a rifle or a shotgun, you can load the gun using conventional methods. Can be advantageously housed in a dummy cartridge, thus helping to simulate normal use of the gun . The term "cartridge" is intended to include bullets, shells, etc.

When the dummy cartridge is finished firing, it will be inserted into the appropriate socket in the portable battery pack. It can be quickly recharged by inserting it into a battery pack.

Therefore, we cannot load the magazine or chamber in the normal way and extract it after firing. Repo, automatic pistol, rifle, shotgun provide dummy cartridges for guns, guns, or other similar handheld weapons. Similarly, medicine packets For those portable weapons with ejectors, the ejected cartridges must be collected and recharged. It can be made so that

It is also possible to incorporate the radiation emitter and its related circuitry into a dummy drug package. However, we place the release in a barrel unit adapted to fit within the barrel of the gun. The projectile is positioned and the dummy cartridge is placed in the firing position within the gun. for electrically connecting the sensor to the barrel unit for energizing the radiation emitter. We have measures in place.

Preferably, the head of the dummy cartridge is biased by a spring; electrical contacts located on or within the rear end of the barrel unit. and preferably protrude into electrical connection with a suitable electrical contact. The spring-biased contact is arranged to be ejected by action of the gun's firing pin.

The expression "firing pin" refers to any type of movable bolt, striker, hammer, etc. It is also intended to include those capable of operating dummy cartridges.

In one preferred configuration, the dummy cartridge includes a cylindrical coaxial contact; This contact extends through a bore in the head of the cartridge and mates with the barrel unit during “fire.” make sliding contact with corresponding contacts. These cartridge contacts are connected to the cartridge by compression springs. the radiator switch is held in its normal rearward position within the Make and break “times” can be adjusted depending on the selected spring rate.

The capacitor may be fixedly disposed within the cartridge casing, but is preferably movably mounted within the capacitor, with one end of the capacitor having a positive or negative contact or carries both positive and negative contacts (these are mounted coaxially or side by side); and the other end cooperates with a firing pin engageable member.

Locating the radiation emitter and associated energizing circuitry within the barrel unit rather than within the cartridge itself The advantage is that these parts are not subject to the mechanical manipulations that cartridges are subjected to; As a result, there is less chance of damage to these parts.

Pulsed radiation emitters allow the target sensor to distinguish between the radiation emitted by the gun and ambient radiation. It is desirable to be able to do so.

A relaxation oscillator powered by a charged capacitor preferably activates the radiation emitter used to do. This oscillator is preferably a unijunction transistor. Another capacitor containing a resistor and determining this emitter voltage is at least When the power supply capacitor of is connected to the relaxation oscillator to start pulsing, its connection between the emitter electrode of the transistor and one of the supply lines from the power supply capacitor and the output from the relaxation oscillator is preferably (taken from the first base B1 electrode of the junction transistor), the second base from the base B2 electrode.

The output from this oscillator circuit is preferably parallel The radiator is connected to a pair of small transistors in the It can be an ode or a laser diode.

A device adapted for storage in a portable weapon for the purpose of and a dummy cartridge adapted to be received within the barrel. The gun barrel unit includes a radiation emitter and an electric energy emitter. a source of energy and a switch means for connecting the source of energy to a radiation emitter; The dummy cartridge relays the firing signal from the gun's firing pin to its switching means. and the switch means is actuated by its signal from the dummy cartridge. It is adapted to be

The power supply inside the barrel unit is, in this case, usually a rechargeable battery, Therefore, this aspect of the invention requires a special battery for the handgun, making it difficult to carry large It is more applicable to belt weapons.

Various arrangements are used to relay the firing signal to the switching means by means of a dummy cartridge. can. In one preferred arrangement, the dummy cartridge contains a piezoelectric crystal. , this crystal emits a high-voltage electrical pulse when the rear end of the cartridge is struck by the firing pin. It is arranged so that it can be used.

This electrical pulse is preferably applied to the front side of the dummy cartridge and the rear side of the barrel unit. to the switch means by a capacitive connection between the dummy drug and Allow a clearance space between the front of the barrel and the rear of the barrel unit, which This is particularly desirable in luva or automatic pistols.

This capacitive connection means that a plate at the rear end of the barrel unit connects to a similar plate or needle at the front of the cartridge. It can be done face to face.

Alternatively, a piezoelectric crystal can power another radiation emitting device within the dummy cartridge. A suitable radiation detector is installed inside the barrel unit and injected into the rear end of the barrel unit. the detector is arranged to actuate the switching means; be able to.

Because piezoelectric crystals are relatively durable, such dummy drug cartridges can be used repeatedly. It can be made to withstand loading and unloading/ejection.

Although the preferred radiation source is an infrared light emitting diode, such emitters emit This beam produces a radiation beam that is The cross-sectional area (circular area) on the target surface is too large.

As a result, optical means are provided which are carried at the end of the radiator. or placed within the barrel unit, thereby reducing divergence and its circular shape to be commensurate with the caliber of the gun and the scaled down range of the target. The area can be adjusted. Such optical means include lenses or sets of lenses. and a reflective surface. However, the shotgun (this In practice it is generally aimed at fixed or slowly moving targets at longer distances. When using handheld weapons other than Delicious.

According to a third aspect of the invention, we provide a device adapted to be housed in a portable weapon. and the assembly includes an electrical source adapted to generate radiation emissions from the gun barrel. a radiator of magnetic radiation; and a source of electrical energy for the radiator comprising a capacitor; , in which the radiator is a laser diode.

Adapted to generate a beam of lasing radiation.

The fourth aspect of the invention is particularly, but not exclusively, applicable to shotguns. .

According to this fourth aspect of our invention, the gun is adapted to be housed within the barrel of a conventional firearm. The self-contained medicine package assembly is placed axially between the radiation emitting part and the switch part. This switch is operated by the gun's normal firing mechanism. and its arrangement is such that the switch section is activated when the gun fires. The radiation pulse is emitted from the radiation part, and the battery part is Provides power for the radiation emitting part.

The switch portion may consist of a piezoelectric crystal actuated by the firing pin, and is preferably or combined with the battery part and the electronic part as a single unit, and this The assembly includes a radiation emitter electrically connectable to the first unit. It is completed with the second unit.

It is sized to fit inside the body unit, and it contains a Suitable positioning means (not shown) are provided for holding the The front end of cartridge 2 when the cartridge is in position within the gun chamber in axial alignment with the barrel. They are spaced closely apart from each other. The gun is repouvre or automatic. Pistols are possible, and in both these cases to simulate multiple firings of the gun. , it is necessary to have a number of dummy cartridges 2.

This dummy medicine package 2 includes a casing 5, and a guide section (not shown) is provided inside the casing. ) is a low-leakage electrolytic capacitor 6 that is slidably mounted in the axial direction. , which has a suitable fitting such as a sliding connection or flexible wire at each end. Hold the electrical connections 7.8 and have the external contacts 9, 1O on the casing 5. , thereby allowing the capacitor 6 to be charged before the dummy cartridge 2 is loaded into the gun. so that Alternatively, the charging connection to the front end of this capacitor can be can be made by a contact pin 11 carried on its front end. This axial direction Its front end 12 of the contact pin 11 has its capacitor attached to a suitable compression spring 13. When in its normal rearward position, which is more biased, several tens of minutes from the tip of the front end 4 Positioned within 1 inch. At the rear end of the capacitor, attach a suitable plunger 1 4, in which the gun's firing pin is connected to the capacitor 6 when the gun's firing mechanism is actuated. and can be engaged to advance the contact pin 11 forward.

Connect the -v6 end of this capacitor to the metal dummy medicine case 5, and connect the +ve end to the appropriate connection to a contact vial 11 that moves through the head 4 of the cartridge made of a suitable insulating material. It would be preferable to

The charging unit for medicine cartridges (not shown) has as many sockets as required, with each The socket has a contact that connects to the outer case 5 of the drug package, and the drug package is inserted into the socket. A spring placed at the bottom of the socket to contact the center pin of the cartridge when inserted. It has a contact point. A small LED is connected in series with the center pin of each socket. This LED lights up when a cartridge is inserted, and when the capacitor is loaded into the gun. The light will turn off when fully charged.

The rear end 3 of the barrel unit l has a contact plate with which the protruding contact pin 11 engages. 15, which is electrically connected to the energizing circuit 16, that is, the circuit of FIG. , in this circuit, the contact plate 15 connects the capacitor 6 via the contact bottle 11 and the plate 15.

Alternatively, a separate metal mask can be used and will be described in detail below in conjunction with FIG.

Capacitor 6 in case of 0.32# medicine package is two 22μF 25V capacitors. possible, they are electrically connected in series and physically arranged in a single column, The capacitors in this combination are then charged to 40 volts before being loaded into the gun. Ru. The total capacitance of those two 22μF capacitors is 11μF, and one 10μF Advantages of using this combination of capacitors instead of μF capacitors is because a 22μF capacitor can be obtained with a smaller diameter than a 10μF capacitor. It is.

For larger cartridges, use one 100μF 40V capacitor, for example. can be set.

The main benefit of using voltages as high as 40 volts is that the stored energy in the capacitor is , if we keep in mind that this is proportional to the square of the voltage for a certain capacity, it is relatively large. That's one thing. Selection of capacity and charging voltage is more sensitive to actual shooting requirements. How many infrared pulses need to be generated to closely simulate or whether you want the user to charge the capacitor after - rounds of firing. Exists.

Dummy cartridges and barrel units intended primarily for pistols or repouvres The modified forms are shown in Figures 2 and 3, respectively, which are similar to those shown in Figure 1. It is generally similar to that of a gun, except that the switch element undergoes a sliding movement when the gun “fires.” They are different. This arrangement only provides more positive contact between the switch elements Rather, they are self-cleaning and also reduce the amount of time they are in contact. Be in control. This contact time determines the number of radiation pulses the emitter emits. It can be advantageously used to determine

Receive 28. The probe contact 30 cannot be slid onto this inner contact 3o. It carries a rounded outer cylindrical globe contact 33. This has not been explained yet For this reason, it is slightly shorter than its inner contact and has a cup-shaped portion 34 at the head. This portion 34 is then pushed into the front end of the inner case 22 and fits there. contacts a cylindrical flange adjacent to the mouth of the inner case. The inner contact point 3o is The inner end has a cylindrical groove portion 35 which is connected to the cup of the outer contact 33. It is received within the shaped head portion 34. These two contacts 30.33 are made of nylon - They are electrically insulated from each other by a sleeve 24, and this nylon sleeve 2 4 extends tightly over the entire length of the inner contact 30 including the flange end portion. Ru. An axially extending slot in the head portion 34 of the outer contact 33 is provided for the negative electrode 29. Provide passageways and contact points. As mentioned above, the head portion 34 of the outer electrode 33 It is pushed into the end of the side case 22 and thus connects the capacitor 23 and the inside. The side and outer contacts 30.33 are mounted rigidly but removably within the inner case 23. It is held in such a way that it

There is an annular space between the front annular surface of the outer contact point 33 and the rear surface of the head cone 27; This is because the inner case 22 moves forward in the axial direction together with the capacitor 23, and and the outer contacts 30, 33. The head cone 27 is It has an axial bore that is counterbored from the rear and has a soft extension sprue. providing an annular support for the ring 36, with the spring 36 in external contact with the annular support; It extends between point 33 and the annular front surface.・Capacitor housing and its contacts The assembly is thus secured to the base of the outer case 21 by means of the spring 36. On the other hand, the head 26 is normally held in a state in which it occupies the pore 25. contact assembly The front end extends through the bore of the head cone 27 and its location is and both free ends of the outer contacts 30.33 are located just at the mouth of its head cone 27. normally positioned on the inside, and its inside contacts 30 are in front of its outside contacts 33.

The gun barrel unit 38 is a switch section. 39, an electronic section 40 (this alternative circuit will be described later), and an IR-LED radiator 4. It consists of 1 and. As can be seen, a simulated “firing” of 20 dummy cartridges is achieved. For this purpose, the chamber 37 and the barrel unit 38 are essentially axially aligned and In most portable weapon designs, the system is A gun that must be "bridged" by Linda and contacts 30 and 33 of the dummy cartridge. There should be a small gap between the ends of the body.

The switch portion 39 of the barrel unit includes an open-ended cylindrical housing 42, which It is a sliding fit within the bore of the pistol barrel and is reduced in diameter to the front. A threaded neck 43 extending in the direction connects this housing 42 to the electronics 40. Ru. Housing 42 includes positive and negative contacts referenced at 44 and 45, respectively. It is growing.

A pair of spring elements constituting this negative contact are attached to an annular spring holder 46. The holder 46 extends from the base in a twice-curved manner, and the holder 46 is connected to the electronic part 40 by a terminal. (not shown) and into the insulating washer 47 in the recess on the front side of the tangent holder 48. Thus electrically isolated from the positive contact 44, this positive contact holder 48 is also connected to the housing 4. Insulated from 2. This tangent point 44 is formed as an elongated bottle and is An expanded head 49 and a plurality of curved strips extending between the head 49 and the intermediate shoulder portion 51. The shoulder portion 51 is bordered by the rear surface of the insulating washer 47. Position the contact within the holder 48 by touching the . Tail of tangent point 44 52 extends forward, that is, toward the muzzle, and comes into contact with the electronic part 40, but the neck of the tail part The part located within section 43 is secured to it by a tightly fitted plastic sleeve 53. It is insulated from the The positive and negative contacts are located at the rear end of the housing 42. It is retained within its housing by a retaining ring 54. Housing 42 screw Around the cut neck 43 is a segmented inflatable plastic washer 5. 5 is provided to receive the tapered end 56 of the barrel unit 38. It has a forwardly extending flange portion of approximately 300 mm. Barrel unit threaded The inner bore engages the outer threaded end of the neck 43 and, as can be seen, the gun By screwing in the pleated head 57 at the front end of the body unit 38, the washer 55 is removed. can be made to inflate, and when the unit is inserted into the barrel of the pistol, That expansion causes the barrel unit 38 to compress as the expanded washer presses against the sides of the barrel. releasably locked within the barrel of the pistol. Instead An appropriate "0" ring can be used as a replacement.

Once placed in its barrel, it is ready for use. When I pull the trigger of the pistol , the coaxial positive contact 3o and negative contact 33 of the bullet are combined into one unit by the firing pin. is advanced across the small gap between the chamber and the barrel unit, and The tangent point 30 slides on the head 49 and comes into rubbing contact with the curved spring 50. become. Similarly, the outer negative contact 33 pushes the inner surface of the curved spring 45 while slides, thereby releasing the cartridge 20 and barrel unit for a single infrared shot from the pistol. Complete the capacitor circuit between unit 38.

For the energizing circuit (one can be selected), see Figures 4 and 5 below. and describe it.

J circuit (this is described with reference to Figures 1, 2 and 3rgJ) (applicable to other embodiments), the capacitor 6.23 is connected to the contact pin 11.3. 0,33 is protruded by the firing pin and the plate 15 (Fig. 1) or contact 44.450 g3), it is connected between the +ve terminal and the -ve terminal.

Oscillator circuit 70 is essentially a relaxation oscillator circuit, which is a unijunction oscillator circuit. Transistor 71% Tl543 (manufacturer unknown, but marked R3) , equivalent to General Electric of America's GE2'N2646. ), but its output lead 72 is a normal unijunction connector. Not from the B1 base electrode of transistor 71, but from its B2 base electrode. There is. The power supply of this oscillator is controlled to 12V by the second Zener diode 73. It is.

The emitter E voltage of the transistor 71 is controlled by a 0.01μF capacitor 74. The charging and discharging of this capacitor 74 is controlled by the switching of the transistor. causing the transistor to generate an output pulse on line 72. .

This output from oscillator 70 on line 72 is connected in parallel through coupling capacitor 75. A pair of transistors ZTX 504 (Ferrxnti) 76.77 in carried. The output pulses from these transistors 76, 77 are connected to resistors RX and Powering the infrared light-emitting diode 17.41 via the effectively parallel resistor 78.79 Ru.

IR-LEDl7.41 (Figures 1 and 3) is Telefunken's TSHA65 03, but TIL38 can also be used.

The benefit of using capacitor voltages as high as 40 volts is that the IR-LED l7.41 The duration of the pulse provided by the oscillator 70 depends on the width of the pulse provided by the oscillator 70. Therefore, the peak amplitude of the IR-LED pulse is mainly affected by the series resistance of its output circuit. It's about being dependent.

Two 10 ohm resistors 7B, 79 are shown in this circuit, and two parallel resistors 7B, 79 are shown. One of each emitter lead of transistors 76 and 77 is connected to a 5-ohm terminal in the output circuit. and a nominally 10-15 ohm resistor RX is connected to the IR-LED cathode. indicated on the code lead. This RX has an input voltage of 4 At 0 volts, it supplies a peak pulse current of 1250mA to IR-LEDl7. conveniently adjusted to do so. The characteristics of this illustrated circuit are as follows. Immediately In other words, the IR-LED pulse current changes when the capacitor voltage drops to 25 ports. , drops to approximately 1000mA, and its capacitor voltage drops to 20 volts. Then, the voltage drops to approximately 800 mA, and the voltage drops exponentially. capacitor is initially charged to 40 ports. I　Vibration of various pulses applied to R-LED Since the width falls off rapidly, there is a need to control the overall duration of that pulse generation. There is no need to provide a timing device.

The maximum current value specified for I R-LEDl 7.41 is 10 microseconds pulse duration. 2.0 amps for continuous periods.

The shape of the current pulse applied to LED 17 is shown in Figure 6a.

Simplified by using only one transistor ZTX 504 instead of 76.77 can do. The following changes are then made to the circuit.

Resistor 81...IOKΩ Capacitor ten--0.022μF (RA45X) capacitor 75-- -0.047μF (YYIOL) resistor 82...220Ω FIG. 5 shows a modification 16' of the circuit of FIG. 4 for use with a laser diode. It shows. Circuit elements that correspond to those in Figure 4 are given corresponding reference numbers. It is.

The laser diode 17' used was a Sharp LTO22MS. Important things means that the pulses applied to such a laser diode are free of high current spikes. For this purpose, pulse shaping stage 83 is connected to the output of transistor 76. This pulse shaping stage is provided between the laser diode 17' and the laser diode 17'. Limit diode current to 67mA. As shown in Figure 6b, the corusa die The current pulse applied to the ord 17' is of rectangular shape. In this circuit layout , the height of the pulse is 67 mA when the voltage on the supply capacitor changes from 40 volts to 17 volts. The pulse is maintained even when the voltage drops to The current and pulse length are significantly reduced.

As can be seen from the above description, dummy cartridges or guns for type I; By introducing a smaller capacitor power supply for use in the body unit, Allows realistic shooting simulations, which can be done a limited number of times without reloading. Especially suitable for serious training, especially in the case of pistols and repoveres that can only be fired. Try to keep it close.

However, once fully charged, the cartridge will retain its stored energy for at least 12 hours. - Maintain the level at a satisfactory value. As a result, we have developed a small portable charging unit for medicine packages. can be used.

In this arrangement The pulse circuit 9o connected to the infrared light emitting diode 91 is connected to the rechargeable battery. battery unit 92, this battery unit is used for small caliber firearms. If so, it will probably need to be a custom mate unit. Each medicine package unit 9 3 consists of a brass case 94 in which the firing pin of the gun can be retained during use. A piezoelectric pulse generator activated by a shock bottle 95 is mounted. Bin 95 is , slidably mounted within a polyamide block 96 and compressed by a compression sprue. The piezoelectric crystal unit 97 is biased by a spring against the rear surface of the piezoelectric crystal unit 97 by a ring 98. to ensure that no rebound occurs when the striker contacts the impact pin 95. to ensure that a clean single pulse is generated by the piezoelectric crystal. Ru. The front end of the piezoelectric unit 97 abuts a grounded brass support plate 99 .

A pulse with an amplitude on the order of 100 to 200 ports is applied to the unit when the firing mechanism of the gun is activated. 97, which is then connected to the emitter plate 101 by an insulated lead 100. This emitter plate 101 is carried by the rear end of the barrel unit 103 during use. It closely faces the corresponding receiving plate 102 . Those plates 101 and 102 The capacitive link between the plates resulting from their proximity results in high input impedance and low output.

When the firing pin activates piezoelectric unit “A”, the resulting electrical pulse The duration of the pulse train of the pulse generator in line “C” is such that this monostable circuit can be It can be preset by adjusting the time. The resultant from this monostable circuit is The square wave output pulse activates the astable pulse generator and this astable pulse generator is designed to generate a train of square wave pulses, each pulse of duration 10 microseconds, the "off" period is 990 microseconds, thus 1.0 milliseconds. The pulse duration is seconds. This pulse train is fed to a small power amplifier, and this The width generator generates a 10 microsecond, 1200 MA peak current pulse train, which is It is supplied to the IR-LED 113 and reaches the target through the lens 11B.

These pulse generators and amplifiers can be similar to those in FIG.

In the case of a shotgun, all of the electronic equipment required by the present invention is contained in one unit within the barrel. There is enough space to accommodate knits. As you can see, optional as space permits. In portable weapons such as rifles, all electronic equipment can be housed within the barrel, and The dummy cartridge is a dummy cartridge that has a space inside the barrel unit, whether it is a capacitor or a piezoelectric device. may contain a slidable bottle that simply serves as an activation member to activate the switch. can. Modifications of this type are within the scope of the invention.

Figure 10 is for glass emitter pulp 17.91.113 of light emitting diode. The mask 120 shown in FIG. Can be used. The manufacture of this mask consists of a sheet of polished metal such as leaded aluminum. Place it on a flat base of soft material such as and with a curvature equal to that of the LED bulb. This is done by pressing a hemispherical indentation with a ball or ball end punch. I can do it. In the center of this hemispherical bowl, a hole 121 is then provided for light emission. . This mask 120 has been shown to increase emission intensity by approximately 20%. Ru.

As an alternative to this, masks can be cast from plastic and made from aluminum or similar materials. It can be made by sputtering a reflective material (this will be removed later). . A hole of appropriate size is provided in the center of the mold for light emission.

Another possibility is to sputter aluminum directly onto the outside surface of the LED . A pinhole is then created by removing a small area of the reflective film.

In the case of the laser diode arrangement described above in connection with FIG. using the mouth, the target is as flat as possible, although some optical correction means will be required. The purpose is to generate a beam of light.

The device of the present invention can also be used for shooting practice or shooting game play. It will be appreciated that it can be used in gun making or toy guns.
