4. DESCRIPTION:

Technical Field of Invention

[0001] The present invention is directed towards firearm training simulators. In particular, the present invention relates to a system and method for simulating recoil and simultaneously sensing the recoil for emitting a laser beam, and marking an aimed target therewith.

Background of the Invention

[0002] Firearm training simulators are devices that simulate the firing of cartridge from various assault rifles, assist trainees to develop marksmanship skills and the like. The simulators largely help military academies to provide exhaustive training to soldiers in real-time and battle-field conditions.

[0003] Conventionally, either live or blank cartridges were employed during the firearm training exercises to emulate recoil sensation. The use of live cartridges in the firearm training exercises proved to involve risk of injury.

[0004] Hitherto, various firearm training simulators utilizing laser beam emitters are know. In such simulators the laser beam is emitted to irradiate or mark a target. Such firearm simulators with laser beams are found to be advantageous as such firearm simulators help the trainees to develop marksmanship skill in a realistic fashion. However, such firearm simulators lack the power of live or blank cartridges to provide the backward thrust.

[0005] Furthermore, one of the commonly employed techniques in firearm training simulators to actuate recoil (backward thrust) is to utilize external gas pressure, mostly through a pneumatic pipe connecting an air compressor with the firearm. However, the employment of pneumatic pipe is found to interfere with the firearm's set-up, and further the firearms modified for firearm training exercises lacks its applicability in the actual firing.

[0006] Additionally, sensing the trigger point of the firearm simulators has been a knotty issue. Early or late sensing could result in misfire. The conventional weapon simulators used various types of transducers for sensing the recoiling effect of the firearm but they left a big scope for false trigger. For example, weapon employing sound sensor to activate laser beam found to be influenced by external sound.

[0007] In the past, the simulators had the laser emitter readily attached to the barrel of the firearm to emit a laser beam in response to the trigger being pulled. The response to the laser transmitter triggering was by means of an energy developed by the firing mechanism of the firearm or the sound energy produced above a threshold level during the firing or the vibration produced by the firearm. Such simulators employed any of the recoiling effects like vibration, sound, flash and shock.

[0008] Accordingly, there is a need for a simulation system and method which would duplicate the recoil of an original firearm, and sense a triggering point of the firearm simulator. Additionally, there is a need to combine a recoil generation means of firearm simulators with a trigger detection thereof such as to provide a realistic feel of recoil, and simultaneously sense the recoil to emit and mark a target with a laser beam.

[0091] The block 804 indicates impaction between a trigger hammer of the firearm simulator with a firing pin of a breach block unit. The impaction between the trigger hammer of the firearm simulator with the firing pin of the breach block unit causes the firing pin to move against the compression force of a compression spring provided therein in the breach block unit. The flow then proceeds towards block 806.

[0092] The block 806 depicts movement of a ball in the bolt unit against the compression force of a compression spring provided therein in the bolt unit. This movement of the ball against the compression force of the compression spring causes regulation of the compressed force from the bolt unit into the breach block unit thereby creating a backward pressure on the breech block unit such that it suffers a backward thrust giving the trainee the feel of firing.
