4. DESCRIPTION;

Technical Field of Invention

[0001] The present invention generally relates to firearm simulators. More specifically the present invention is concerned with a firearm assemblage and method in the direct firearm simulators which would provide an improved recoil sensation to trainees of the direct firearm simulators.

Background of the Invention

[0002] Direct fire arms simulators are devices that simulate the firing of cartridges from assault rifles such as Insas 5.56mm, AK-47, pistol and the like during training exercises. This largely helps military academies to provide exhaustive training to soldiers in real-time and battle-field conditions.

[0003] Conventionally, two types of firing are employed during training exercises. One is with live cartridges and the other with blank cartridges.

[0004] The training exercises conducted using blank cartridges emulate live cartridge firing in terms of flash, vibration and sound. In spite of being safe and emulating the live cartridge to an extent, the blank cartridges lacks the power to provide the backward thrust the shooters need during training exercises.

[0005] One of the commonly employed techniques in conventional direct 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 simulator. Such conventional technique responds to the movement of trigger to produce recoil which gives the trainee the feel of firing. However, the utilization of pneumatic pipe interferes with the firearm setup, and the firearm modified for training loses its applicability in actual firing.

[0006] In the light of aforementioned discussion there exists a need for a system and a method that could be easily integrated with the firearms, and would provide an improved recoil sensation to the trainee of the direct firearm simulator.

Brief Summary of the Invention

[0008] Another objective of the present invention is to overcome or at least ameliorate the disadvantages prevailing in the conventional direct firearm simulators associated with the recoil system employed therein.

[0009] Further another objective of the present invention is to provide a recoil system in the direct fire arms simulators that would facilitate the trainees with almost the actual feel of firing, would not interfere with the firearm setup, and would preserve the applicability of the firearm in actual firing.

[0010] Yet another objective of the present invention is to provide a recoil system that would be easily be assembled and disassembled from the original firearms or modified and Drill Practice weapons, and would emulate the corresponding recoil sensation.

[0016] According to the second aspect, the method for providing the improved recoil sensation to the trainee of the direct firearm simulator further includes regulating flow of the compressed force from the magazine unit into a bolt unit.

[0017] According to the second aspect, the method for providing the improved recoil sensation to the trainee of the direct firearm simulator further includes regulating flow of the compressed force from the bolt unit into a breach block unit, wherein the regulation of flow of the compressed force from the magazine unit into the bolt unit, and from the bolt unit into the breach block unit is characterized by interoperable assemblage of the bolt unit, and the breach block unit with the magazine unit.

[0049] Referring to FIG. 3a and FIG.3b are diagrams 300 illustrating an isometric view and a sectional view of a bolt unit of a firearm assemblage. As best seen in FIG.3b, the bolt unit 300 includes a cylindrical bolt 302, a compression spring 304 axially placed with a ball 306, a stopper means 308 rigidly assembled to the cylindrical bolt 302 for sealing the ball 306 and the compression spring 304, and an inlet pin 310.

[0050] The cylindrical bolt 302 includes a provision having the compression spring 304 guided thereon along with the ball 306. The inlet pin 310 is coupled with the provision for regulating flow of the compressed force from the magazine unit into the bolt unit 300.

[0051] Referring to FIG. 4a and FIG.4b are diagrams 400 illustrating an isometric view and a sectional view of a breach block unit of a firearm assemblage. As best seen in FIG.4b, the breach block unit 400 includes a breach block carrier 402, a piston 404 movably mounted into the breach block carrier 402, the piston 404 having a head portion which is in seal engagement with a piston sealing means 410 located onto the outer periphery of the piston 404.

[0052] The breach block unit 400 further has a provision axially provided along the piston 404. The provision has a firing pin 406 movably guided along a compression spring 408, and a stopper pin 412 guided into and rigidly fixed to the piston 404. The stopper pin 412 acts as a stopper for the firing pin 406 and further enables the firing pin 406 to acquire a sliding motion along with the compression spring 408 inside the piston 404.

[0053] FIG.5 is a diagram 500 illustrating a methodology adapted for providing an improved recoil sensation to a trainee of a direct firearm simulator. The flow starts at step 502 depicting storage of a predetermined measure of compressed force into a chamber contained in a magazine unit. The magazine unit includes an orifice for guiding the compressed force into the chamber, and another orifice for regulating flow of compressed force from the chamber. The flow then proceeds towards block 504.

[0054] The block 504 depicts securely coupling of a magazine unit with a bolt unit. Flow then proceeds towards block 506.

[0055] The block 506 depicts regulation of flow of the compressed force from the magazine unit into the bolt unit. The regulation of flow of the compressed force from the magazine unit into the bolt unit is achieved upon association of an inlet pin of the bolt unit with a ball of the magazine unit against the compressed force inside the chamber, which generally happens when the bolt unit gets securely coupled with the magazine unit The flow then proceeds towards block 508.

[0056] The block 508 depicts initiation of a trigger action by the trainee. The trigger action generally gets initiated once the trainee actuates a trigger drive associated with a firearm. The flow then proceeds towards block 510.

[0057] The block 510 depicts regulation of flow of the compressed force from the bolt unit into a breach block unit. The regulation of the compresses force from the bolt unit into the breach block unit is defined by the triggering action as depicted above in the block 508. The regulation of flow of the compressed force from the bolt unit into the breach unit is achieved on slidable push of a ball of the bolt unit against a stopper means provided therein for seal engaging the ball. The slidable push of the ball of the bolt unit against the stopper means induces movement of the compressed force into the breach block unit generating a backward pressure thereby giving a recoil sensation to the trainee.

[0058] The regulation of flow of the compressed force from the bolt unit into the breach unit is further achieved upon association of a firing pin of the breach block unit with the ball of the bolt unit. The association of a firing pin of the breach block unit with the second ball of the bolt unit induces movement of the compressed force into the breach block unit generating a backward pressure thereby giving a recoil sensation to the trainee. The flow finally ends at this block.

[0059] FIG.6 is a diagram 600 depicting a sequence of events which regulates flow of compressed force from a magazine unit into a bolt unit, according to an exemplary embodiment. The flow starts at block 602 depicting assemblage of a bolt unit with a magazine unit such as to form a secure coupling between the bolt unit and the magazine unit. The flow then proceeds towards block 604 depicting association of an inlet pin of the bolt unit with the ball of the magazine unit. The assemblage of the bolt unit with the magazine unit causes the inlet pin to push the ball of the magazine unit against the compressed force thereby regulating the flow of the compressed force in the chamber of the magazine unit into the bolt unit. The flow ends at the block 604.

[0060] FIG.7 is a diagram 700 depicting a sequence of events which regulates flow of compressed force from a bolt unit into a breach block unit, according to an exemplary embodiment. The flow starts at block 702 describing initiation of a trigger action in a firearm simulator. The trigger action is initiated through a trigger drive of the firearm simulator. Flow then proceeds towards block 704.

[0061] The block 704 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 706.

[0062] The block 706 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.

[0063] The firearm assemblage of the present invention providing an improved recoil sensation is not limited in terms of its utilization to a particular type of direct firearm rather it can be equally used in all sorts of direct firearm weapons like original weapons or modified weapons, Drill Practice (DP) weapon and the like. Further size, shape of the magazine unit of the firearm assemblage replicates shape and size of the original magazine such as to provide realistic feel to the trainees.

[0064] Although illustrative embodiments of the present invention have been described in detail herein with reference to accompanying drawings, it is to be understood that the invention is not limited to these precise embodiments and that various changes and modifications can be effective therein by one skilled in the art without departing from the scope and spirit of the present invention as defined by the appended claims.
