FIREARM TRAINING APPARATUS AND METHOD

Abstract

A firearm training apparatus and method provides simulated weapon realism that places higher priority to shot placement by using a culminated laser beam with specific target areas to achieve marksmanship accuracy. Trainee shooters can visually observe hits by an LED in the target area and hear an alarm sound when another trainee is hit. Stress and reaction to stress is achieved through the use of a TENS (transcutaneous electrical nerve stimulation) units in vests worn by the trainees. Greater realism is achieved by eliminating special safety equipment required with projectile systems, and focus on weapon accuracy and firing characteristics.

Description

FIELD OF INVENTION

The present invention is directed towards a system for simulating firearm training.

BACKGROUND

Firearm simulation system exist that use guns having a laser output and laser sensors to detect hits. Firearm simulation participants will wear the laser sensors and shoot the laser gun at other participants. When a sensor worn by a participant is struck by a laser, the system can record the strike. This type of a simulation system can be known as a “force on force” system. Most force on force systems are basically laser tag systems that may user laser guns that are not similar to actual firearms. These systems may transmit an uncomfortable or painful signal to a user who has been hit by a laser beam. Even with the elimination of safety equipment, existing force on force firearm training systems fail to achieve the level of realism required to enhance the firearm training experience. Some existing systems place a strong emphasis on providing electrical shock as a means of informing the player that they have been shot. Because this electrical shock can be painful, the participant can practice the ability to “Fight through the Trauma”. While certainly pain feedback can be important, the other aspects of realistic training have been ignored by prior art firearm training systems. What is needed is a more realistic firearm training simulation system.

SUMMARY OF THE INVENTION

Most laser engagement systems function on the design premise that a laser strike or Hit renders the target acquired and the subject identified as a casualty. Hits are stressed without regard to marksmanship skills allowing deterioration of learned skills. Training focus is on the ability to fight through stress and less on target accuracy. Apart from other systems, the inventive firearm training apparatus and method simulates weapon realism. The inventive apparatus can be implement through conversion kits that allow users to convert live handguns into blank firing weapons that replicate all live fire characterizes. A uniquely designed chamber used with the firearms allow the trainees to experience the effects of weapon fire without the risks of chambering live rounds. The firearm training apparatus and method also places higher priority to shot placement by using a culminated laser beam with specific target areas to achieve marksmanship accuracy. Fiber optic pads allow smaller target areas that are arranged over specific target areas. Shooter can visually observe hits by an LED in the target area and a sound alarm when hit. Stress and reaction to stress is achieved through the use of a TENS (transcutaneous electrical nerve stimulation) unit. Greater Realism is achieved by eliminating special safety equipment required with projectile systems, and focus on weapon accuracy and firing characteristics.

DETAILED DESCRIPTION

The inventive firearm training apparatus and method was designed to realistically simulate actual firing of ammunition with a real firearm. In order to provide a realistic simulation, a real handgun or long gun is adapted for simulated firing so that the same principles and characteristics in the real weapon would be the same as the simulated actuation.

The inventive firearm training apparatus can include a simple laser conversion kit that can be used to change a fully functional duty weapon firearm to a blank firing training weapon that emits a laser beam when the blank when the firearm is fired. The system can also include sensor components that are worn by the system users to monitor the training participants and record laser beam hits. In an embodiment, the sensor components can transmit the hit data to a computer which can record the laser beam hits associated with each trainee and provide information about the location of the hit and the source of the hit. Each laser can be encoded with a signal indicating the laser source and each sensor mechanism can transmit a signal identifying the sensor mechanism that received the laser hit. The system computer can match the laser source and the sensor identities to produce cumulative information regarding which laser hit which sensor which can then be used to produce reports that can describe many statistics which can include: the number of rounds fired, the accuracy of the shooter, the locations of the hits on the trainees, etc. A benefit of the inventive firearm training is that the trainees use the same weapons, magazines, and types of ammunition in the simulations as the actual firing of the firearms. Because the actual guns are used to fire blank ammunition, the feel, recoil and sound can accurately replicate the same guns firing live ammunition.

Existing force on force firearm training systems can provide target areas that cover the body area and in some cases these systems can inaccurately record hits that are beyond the target area because the size of the laser beam can be greater than the diameter of the live ammunition. Thus, these systems may inaccurately record laser hits when actual ammunition would have missed the target. Having specific target areas on the subject is a feature of the inventive firearm training system. Thus, the inventive system may only record laser hits that would be hits using live ammunition. This improved hit reporting can reinforce marksmanship skills and ensure that the trainees receive accurate feedback and results for delivering lethal shots.

In an embodiment, the inventive firearm training system can include an ocular target which can allow sniper trainees to participate in training simulations. The ocular target is a long range firing mechanism that provides laser simulation of the type of shot required to eliminate specific types of target.

In another embodiment, the inventive firearm training can include a detachable target box that allows the use of vehicles in active shooter simulation scenarios. A vehicle target system can use infrared conducting plastic on a self-contained unit that can be placed on the vehicles to transmit laser strikes to a laser sensor. The infrared conducting plastic can be placed on side window or headrests. The target box can detect laser hits and transmit this information to the system computer to record the hit and hit source.

The laser sensor device worn by the trainees can include a stress feedback mechanism which provides a physical signal to the trainee when the laser sensor is struck by a laser beam during the training simulation. The physical signal can be an electrical signal that is managed through the use of a TENS (transcutaneous electrical nerve stimulation) unit. The TENS unit can deliver an electrical nerve stimulating pulse to muscles that have a wide range signal strengths. In different embodiments or feedback setting or based upon the sensor location, the nerve stimulating pulse can range from a low setting that provides a numbing sensation to a high setting that can incapacitate a muscle group. Realism of the inventive firearm training simulation can be further enhanced by the environment and locations where training can be conducted. The inventive system can include equipment that can be used in any environment.

The inventive firearm training system uses features and technologies to achieve a realistic force on force firearm training system. In an embodiment, the inventive system includes an adapter or converter to change most semi-automatic handguns into blank firing weapons that fire blanks but accurately simulate the characteristics of that weapon firing live ammunition. Trainees can participate in the simulations using assigned weapons which can built skill sets required to master the user of a particular weapon.

In an embodiment, the a laser system utilizing a culminated coded laser adapted to a specialized barrel that is adaptable to handguns and long guns and allows subject short where weapon is aimed. A vest used by the inventive system provides visual, auditory, and tactile feedback when a subject wearing the vest is hit in a target area. A true ocular target comprised of plastic glasses connected to the vest that allows for snipers to be integrated into force on force training exercises. In an embodiment, the inventive system can also include a vehicle target system utilizing the same targeting system in a self-contained unit that can attached to the side window or headrest of any vehicle.

The inventive firearm training system will be described with reference to the following drawings. FIG. 1 illustrates an embodiment of a laser assembly 100 which can be directly coupled to a pistol or rifle. The laser assembly can include: an infrared laser module 101 coupled to a printed circuit board 105. When the trainee firing the firearm actuates the laser assembly 100, the printed circuit board 105 can activate the firing of the laser module 101 which can emit a coded infrared laser beam. The coding in the laser beam can be an identification code used to identify the laser assembly 100. Each trainee can have a separate laser assembly 100 each of which has a different identification code. The coding can be in the form of pulsed laser signals emitted by the infrared laser module. Although the laser assembly 100 is described as using infrared light, in other embodiments, the laser used can output any other type or wavelength of light. The printed circuit board 105 can include a processor controller 111 that can transit the identification signals to the laser module 101 and be actuated by a pressure switch 115. In other embodiments, the laser module 101 can include an audio sensor 116 such as a microphone coupled to the processor controller 111. The processor controller 111 can actuate the laser module 101 when the audio sensor 116 detects an audio signal greater than a predetermined audio value. The printed circuit board 105 can also be coupled to a battery 109 for powering the laser assembly 100 components.

In an embodiment, the laser assembly 100 can include a status LED(s) 113 which can emit different colors to indicate the status of the laser assembly 100. A green light may indicate that the laser assembly 100 is operating properly and a red light may indicate a problem. Because an infrared laser is not visible, the LED light 113 may be the only mechanism that can provide confirmation that the laser assembly 100 is working properly.

With reference to FIG. 2A, an embodiment of a universal laser barrel housing 200 is illustrated and with reference to FIG. 2B, a cross section view of an embodiment of a universal laser barrel Housing 200 is illustrated. The universal laser barrel 200 can contain an infrared laser assembly 100. The housing 200 can have threads 201 which can be coupled to corresponding threads on the end of the pistol or rifle barrel to secure the housing 200 to the end of a pistol or rifle and a laser port 209 for the laser module 101 on the laser assembly 100. The universal laser barrel housing 200 can be internally modified to secure any other embodiments of the laser assembly 100 to the firearm. The universal laser barrel housing 200 can also be configured to actuate a pressure switch to fire the laser module 101 in the laser assembly 100 and vent gases from the firing of a blank firearm cartridge. In order to relieve internal pressure, the housing can include many vent holes 203 which can allow the gases from the fired blank cartridge to escape the housing 200. This housing 200 provide a means to house an electronic components on the laser assembly 100 within a gun barrel and protect them from the pressure and hot gasses that result from the firing of a blank cartridge used to operate the gun mechanism in the simulation of a given semi-automatic action sequence. The housing 200 can also provide user access to the electronic components on the laser assembly 100 to test actuate a pressure switch and to provide visible access to LED lights on the electronics which can indicate the status of the operational status of the electronics through a laser status LED viewing hole 207.

FIG. 3 illustrates an embodiment of a laser training vest 300 that can be worn by trainees. In an embodiment, the laser training vest 300 can incorporate multiple fiber optical pads 301 that can be arranged in a target specific order to receive coded infrared laser hits from the blank firing training pistols or rifles. In an embodiment, the training vest can indicate a laser beam hit by activating a light emitting diode(LED) 303 in a corresponding specific targeted area and activating a sound alarm when specific located optical pads 301 are hit with a gun or rifle fired infrared laser. In an embodiment, the LEDs 303 can be red. The optical pads 301 and the LEDs 303 can be coupled to infrared detector sensor boards 305 which can process signals from the optical pads 301 and actuated the LEDs 303 when the optical pads 301 are hit with an infrared laser. The sensor boards 305 can be coupled to controller electronics 307. Optionally the vest 300 can also trigger or actuate transcutaneous electrical nerve stimulation (TENS) 309. When the laser beams hit the fiber optical pads 301, the system can actuate the TENS 309 which can be stress inoculators that can enhance the training experience. The TENS 309 can be actuated by the controller electronics 307. Batteries 311 can power the vest 300 components.

The front of the vest 321 can include the optical pads 301, the infrared detector sensor boards 305 and the back of the vest 323 can include the controller electronics 307, TENS 309 and batteries 311. In an embodiment, the vest 300 can be modified by adding additional optical pads 301 which can be added to the front of the vest 321 or the back of the vest 323. The vest 300 can include additional optical pad connectors 313 which can be used to connect additional optical pads 301 and detector sensor boards 305 to the vest 300.

FIG. 4 illustrates an embodiment of a handgun chamber block 401. The inventive chamber block 401 design can minimizes machining requirements. The inventive chamber block 401 design can also generating enough pressure when a blank is fired to replicate live fire characterizes of sound and recoil. The chamber block 401 can also provide an atmospheric vent hole 405, directly from the blank round chamber 413, for the direct discharge of gases from a fired blank round. The chamber block 401 can also include a pressure switch vent 409. Some of the internal pressure is used to actuated the pressure switch and any excess pressure can be vented out of the chamber block 401 through the pressure switch vent 409. However, the chamber block 401 can also allow the gun barrel to be sealed from the gas pressurization and flow, for the purpose of the installation of sensitive electronic packages. In an embodiment the blank round chamber 413 can be a custom chamber used for specific types of blank cartridges.

When firing a blank round, the gases created by the burning powder must be vented in a manner to allow proper back pressure within the gun barrel chamber, in order to control the amount of energy transferred from the expanding gasses into the gun slide and the gun barrel. If the gun barrel is utilized to contain sensitive electronic packages that cannot withstand the violent pressures and gas flow from a gun powder discharge other means of gas venting must be provided which remain sealed from the gun barrel pathway. The system should also allow the gun to operate successfully as a blowback operation by providing the firing and semiautomatic operation of a normal ballistic fired momentum transferred operation. By strategically configuring the vent hole of the chamber block to vent out the top of the gun chamber, the gas energy can be directly transferred as recoil and noise. The recoil and noise parameters are required for training purposes to allow the gun in laser simulation mode to act like the actual gun and provide the feel of firing a live bullet based round. Capturing the expanded gases within the gun chamber also allows maximum energy to be utilized to move the slide back and control the barrel position for a successful ejection and reloading of a new blank round. Placing the vent hole directly in the gun chamber allows the vent hole diameter to be specified and optimized to the correct size, in order to balance barrel spring loads, gun recoil, gun noise, and the ejection and loading of new rounds for semi-automatic gun performance.

FIG. 5 illustrates an embodiment of a leaf spring 411 used with the barrel block 401. A leaf spring 411 can include a slanted portion 417 and can be secured to the top of a handgun barrel block 401 to force the barrel into its correct load and eject position, thru the motion of the slide over the slanted spring 411. In order to facilitate the rearward motion of the barrel block 401, a spring resistant device can be placed in the path of the rearward moving slide in order to allow the slide force to catch the barrel motion and move the barrel in a backward motion. A spring 411 or a spring type device attached to the barrel 401 can catch the slide rearward motion and converts the slide energy into a rearward motion of the barrel. Furthermore the spring 411 can allow for a smooth transfer of the slide energy through the deformation of the spring 411, which avoids a destructive impact type transfer, if a solid material was used in the transfer of energy from the motion of the slide to the barrel block 401 motion.

The spring 411 can be very important in that it not only reverses the motion of the barrel block 401 from a forward motion to backward motion, but it also imparts a downward force which assist the barrel block 401 to move downward, as required, to allow the proper position of the barrel for electing the used round and the loading of a new round from the gun magazine. Also the size of the spring 411 allows for balancing the energy transferred from the blank round to the barrel block 401 and slide motion; thereby controlling the amount of gun recoil and gun sound level.

FIG. 6 Illustrates a compression spring 601 within a universal laser barrel 200 that is coupled to a barrel block 401. In an embodiment, a compression spring 601 can be placed over the modified barrel block 401 of the firearm, to force the barrel block 401 into its correct load and eject position, thru compression of the spring 601, by the rearward motion of the gun slide. In order to facilitate the rearward motion of the barrel block 401, a spring 601 is placed in the path of the rearward moving slide, in order to allow the slide force to transfer its rearward motion to the barrel block 401 and move the barrel block 401 in a backward motion. A coiled compression spring 601 can be attached to the barrel block 401 and can catch the slide's rearward motion and converts the slide energy into a rearward motion of the barrel. Furthermore the spring can allow for a smooth transfer of the slide energy through the deformation of the spring, which avoids a destructive impact type transfer, if a solid material was used in the transfer of energy from the motion of the slide to the barrel motion. The compression spring 601 can also be important because it not only reverses the motion of the barrel block 401 from a forward motion to backward motion, but also allows for the balancing of energy transferred from the fired blank round to the barrel block 401 and slide motion, thereby controlling the amount of gun recoil and gun sound level.

For some firearms, a nose piece 603 can be required around the front of the smaller diameter laser barrel to keep the laser barrel centered with the gun slide and receiver to assure the laser beam is on gun centerline for accurate aiming. The nose piece 603 can also be required to keep the barrel spring 601 from protruding thru the end on the gun slide.

FIG. 7 illustrates a blank firing attachment assembly 620 for automatic rifles with a flash suppressor. The attachment body 613 can be threaded into the flash suppressor nut 611 which is attached to the existing flash suppressor on the automatic rifle utilizing the grooves of the flash suppressor to restrict flow of gases out the barrel to cycle the rifle in automatic or semi-automatic mode. Contained with the attachment body 613 is a laser assembly with actuates an infrared laser duplicating the exact path of a live round. This attachment body 613 can hold the gas flow restrictor 631 which is within the attachment body 613. The laser module 101 can be attached to the gas flow restrictor 631 on one end and the opposite end of the gas flow restrictor 631 can be attached a safety rod 615 that can extend into the firearm barrel.

FIG. 8 illustrates an embodiment of ocular infrared detection glass system 640. The laser beam shall be emitted from a handgun or rifle during the firing of a blank round toward the person wearing the ocular infrared detection glasses 641. When the laser beam strikes on any part of the glasses 641 surface, the glasses 641 mounted IR sensor(s) 643 sends a signal to the infrared sensor receiver 645. The infrared sensor receiver 645 can confirm that the laser signal contains the correct code and signal strength confirming a laser strike from an authorized laser source. The infrared sensor signal then allows the LED light 647 on the glasses 641 to be turned “on” to confirm an accurate and correct strike. The glasses 641 can be made from Lexaniu and can contain laser detection sensors 643 and can be connected to an optical cable that is attached to the infrared sensor receiver 645 in the vest. When the laser detection sensors 643 are hit, the system can activate the LED 647 located on the glasses 641 as well as the audio buzzer and TENS unit located on the vest system.

The infrared laser sensor receiver 645 can also send an approval signal to the system controller 647 which contains a power supply 649 to supply various power requirements to system parts that are turned “on” to signal a laser hit; including the LED power via the infrared laser receiver 645. Other laser receiver components that can require power can include: a buzzer which provides an audible signal of a laser strike and a “on” signal to a TENS skin stimulator 651 which inputs a high voltage skin input to the user. The controller 647 power supply 649 can also drive an onboard computer chip which determines timing and sequencing of these functions. A master power switch on the controller 647 can provide manual system component activation. The ocular detection system is battery 649 powered with a portable self contained system to allow a user total freedom of movement. The ocular detection system 640 can be integrated with other body infrared sensors to detect infrared strikes on other parts of a users body.

FIG. 9 illustrates a portable, self contained, infrared laser detection system 660. Infrared detection sensors 661 can be mounted on a plastic infrared receiving and transmission plate 663. The sensors 661 may be fiber optical receiver pads or infrared sensor chips which are mounted on the back of a window box plastic receiver plate. Sensors 661 can be arranged in a target specific order to receive coded infrared laser hits from a blank firing training pistol or rifle. The sensors 661 can be coupled to detector sensor electronics 665 which can be coupled to controller electronics 667. When the infrared detection sensor 661 is hit with a laser, the hit signal is transmitted from the sensor 661 to the detector sensor electronics 665 which can illuminated the LED 659 to provide a visual indication of the laser hit. A battery 669 can power the components of the laser detection system 660.

In an embodiment, the laser detection system 660 can be used with other targets such as vehicles 670. For example, in an embodiment, the laser detection system can be used as part of a vehicle target system which can use the infrared conducting plastic materials 663 and sensors 611 within a target vehicle 670. For example, the plastic infrared receiving and transmission plate 663 can be placed on a vehicle window or within the vehicle 670 in areas that would indicate a trainee hit such as a headrest. The laser detection system 660 used in a vehicle 670 can function in the same manner described above.

This window box system can be used in conjunction with a pistol or rifle incorporated infrared laser module, designed and integrated with a printed circuit board, to activate the firing of a coded infrared laser beam. The infrared laser beam sends a coded signal when activated by a pressure sensitive switch or a sound sensitive switch, when using a blank firing pistol or rifle.

FIGS. 10A and 10B illustrate side views of embodiments of blanks used with firearms during the simulation training. FIG. 10A illustrates a 9mm blank that can be formed from a 9 mm win mag case. Similarly, FIG. 10B illustrates a 0.40 cal blank that can be formed from a 10 mm mag case. Each of these rounds can be formed with special dies and can conform to uniquely reamed chambers. In an embodiment, the illustrated shoulder can be added to the blank so that it conforms to the contour of the chamber. Another feature of the inventive blanks is the narrow top of the blank which prevents live rounds from being chambered. A standard profile blank that would fit a standard chamber may not properly function with the modified training guns. Because of these special configuration features, no other commercially available blank will fit into the corresponding reamed chambers.
