The present disclosure generally relates to an electro mechanical firing control apparatus, and more specifically to an electro mechanical firing control apparatus that enables control of the firing of an automatic or semi-automatic firearm.
The automatic firearm was developed over a century ago, and has been in use, in combat, ever since. Modern automatic firing mechanisms are usually mechanical systems that enable a user to switch between firing one round per trigger engagement or multiple rounds consecutively until the trigger is released, based on a simple mode change of the safety lever, as disclosed also in the US patent “AUTOMATIC MACHINE-GUN” U.S. Pat. No. 1,293,021 by J. BROWNING dated 1916. The use of an automatic firing mode, enables firing rounds at a high rate. Most automatic firearm's fire rate range is between 650 to 1200 rounds per minute (“RPM”). The fire rate is mainly affected by the physical characteristics of the mechanical mechanism of the firearm, which relies on the pressure created by the gas emissions originating from the gunpowder combustion process, of each round fired. When a round is fired, some of the gases that are emitted during the combustion of the gunpowder are directed to push a bolt carrier assembly within the firearm, which cocks the hammer of the firearm. In some firearms the possibility of regulating the fire rate can be changed by setting the pressure of the returning gasses. This is usually dune by using a mechanical regulator, enabling only a few different operation modes, as described, for example, in the NEGEV® Light Machine Gun (LMG) manufactured by IWI.
The movement rate of the bolt carrier assembly and hammer, which controls the fire rate in an automatic mode of the firearm, are set by the mechanical mechanism designed by the manufacturer of the firearm. Therefore, the automatic firing rate of a firearm is typically set by the physical characteristics of its mechanical mechanism.

Some non-limiting exemplary embodiments or features of the disclosed subject matter are illustrated in the following drawings.
In the drawings:
With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the disclosure. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the disclosure may be practiced.
Identical or duplicate or equivalent or similar structures, elements, or parts that appear in one or more drawings are generally labeled with the same reference numeral, optionally with an additional letter or letters to distinguish between similar entities or variants of entities, and may not be repeatedly labeled and/or described. References to previously presented elements are implied without necessarily further citing the drawing or description in which they appear.
Dimensions of components and features shown in the figures are chosen for convenience or clarity of presentation and are not necessarily shown to scale or true perspective. For convenience or clarity, some elements or structures are not shown or shown only partially and/or with different perspective or from different point of views.
Some embodiments of the present disclosure provide a user of an automatic or semi-automatic firearm with the ability to control the fire rate and/or the number of rounds fired while using the firearm. A user of an automatic or semi-automatic firearm, i.e. a shooter, may be for example a human shooting the firearm, an automatic mechanism for example a robot and/or a remote controlled device. As mentioned above, some known systems provide a user, using the mechanical mechanism of an automatic or semi-automatic firearm, with the ability to fire rounds at a high rate, such high rates may sometimes reach up to 1200 Rounds Per Minute (RPM). At such high rates, the recoil effect of the firearm may impact the ability of the user to steadily hold the firearm, resulting in a decreased stability of the shooter. As a result, the shooter may easily be deviated from the aimed target and the accuracy of the shooting may decrease. Combined with the automatic firing recoil effect at high rate, the reduction of the shooter's stability may also have an effect on their ability to properly realign the firearm with the designated target. The difficulty to realign the firearm may result in the reduction of accuracy when firing more than one round at a time, and of the overall effectiveness of the shooter, for example in combat situations, where the time it takes to realign the firearm and/or aim is critical.
According to some embodiments of the present disclosure, the apparatus disclosed may reduce the fire rate of a firearm according to the user's requirements, which may vary from one user to another. For example, one user might use a bipod when firing the firearm and therefore may set the apparatus to fire rounds at a rate of 800 RPM, while another user may mainly use the firearm while standing, and therefore may wish to set the fire rate to 300 RPM. The apparatus may enable switching between RPM modes according to the user's requirements on site and according to a specific situation, without the need for a professional assistance and/or hard-to-get equipment.
As mentioned above, in known systems, a firearms' RPM is defined and/or set as a result of the firearms design and/or manufacturing process. Since the RPM is a direct result of the firearms mechanical structure, changing the firearms design and/or manufacturing process might affect the firearms overall performance. For example, using a less powerful spring to push back the bolt carrier assembly/slider, may reduce the overall RMP but may also cause the firearm to malfunction more frequently and/or easily. As disclosed above other known solutions for controlling firing rate, may regulate the amount of gases used to push back the bolt carrier assembly or slider. These solutions may be limited to a few predesigned gas operated firearms and may not be accurate or be an easy to apply solution. Furthermore, changing the amount of gases used for pushing back the bolt carrier assembly/slider may arise the same problems as mentioned when changing the mechanical structure of the firearm. However, according to some embodiments of the present disclosure, the apparatus disclosed may solve the presented problem by reducing the fire rate of a firearm without affecting other performance and/or operation aspects of the firearm. Furthermore, the apparatus may be compatible with a variety of firearms and is not limited to one design or operation principle. For example, the apparatus may be placed vertically, horizontally and/or at any other required position, depending on the structure and/or operation aspects of the intended firearm.
According to some embodiments of the present disclosure, the apparatus disclosed may also resolve some of the maintenance challenges, such as deterioration of the firearm due to mechanical strain. The firing rate of the firearm may cause fast and powerful contact between components of the firearm, which may cause them to wear out faster. Therefore, reducing the firearm's fire rate may help prolong the firearm's lifetime. Furthermore, the intense friction of the different components may cause them to heat fast, which may result in the reduction of the effective performance of the firearm and the need of increased maintenance. The control and/or reduction of the fire rate may help reduce the rapid heating and maintain the firearm. For example the overheating of the barrel which may cause it to deform. Furthermore, the use of the apparatus may help the user and/or maintenance professional to know and/or asses the firearms operational status. Knowing the firearms operational status may help prioritize maintenance requirements and therefore may result in saving money and/or time.
Therefore, some embodiments of the present disclosure solve the problems caused by an excessive firing rate, as described above, by enabling easy control of the firing rate of a firearm, e.g., the rate at which the rounds are fired from the firearm. For example, the firing rate apparatus may electromechanically control at least one mechanical element participating in the firing process such as, a trigger, a sear, a bolt carrier assembly, a slider, a hammer and/or firing pin, for example by using an electromagnet or an equivalent electronically controlled actuator.
Some embodiments of the present disclosure may include a system, a method, and/or a computer program product. The computer program product may include a tangible non-transitory computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present disclosure. Computer readable program instructions for carrying out operations of the present disclosure may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including any object oriented programming language and/or conventional procedural programming languages.
Before explaining at least one embodiment of the disclosure in detail, it is to be understood that the disclosure is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The disclosure is capable of other embodiments or of being practiced or carried out in various ways.
Reference is now made to
EMFC apparatus 100 may not operate and/or enable the mechanical firing system of the firearm to fire unless set to a predefined mode. Switching the safety lever (shown in
Processor 121 may use communication unit 123 to receive and/or send data to an external device, for example a smartphone, tablet and/or other computerized devices. For example, processor 121 may receive instructions, for example according to reprogramming the preselected rules or according to choosing the predetermined rules stored in a non-transitory memory readable by the processor. For example, the predetermined rules include at least one of firing preselected number of rounds per specific time, as long as the trigger is engaged; firing up to a preselected number of rounds, as long as the trigger is engaged; firing a number of rounds with preselected time gaps between them, as long as the trigger is engaged; First Hit (FH)—firing a first round upon the engagement of the trigger and according to a command from the processor, and the other consecutive rounds according to a command from the processor, as long as the trigger is engaged and/or Two Hit (TH)—firing a first round upon the engagement of the trigger, and firing the following consecutive rounds according to a command from the processor, as long as the trigger is engaged or a combination thereof. Processor 121 may also use communication unit 123 to send feedback regarding the operation conditions of the firearm, for example via Wi-Fi, Bluetooth, NFC, cable or any other means and/or methods for transferring and/or communicating data. For example, during a maintenance inspection, processor 121 may send to the maintenance professionals' computerized device indication regarding the firearms status. For example, the number of rounds fired since the last inspection, the number of rounds fired since the firearm was manufactured, the number of malfunctions that occurred during a specific time period, the sequence of firing/operations prior to a malfunction and/or other information that might be relevant for the maintenance inspector. It should be noted that using communication unit 123 may enable a remote access to the firearm firing system. For example, a user may instruct processor 121, via communication unit 123, to fire the firearm via remote access, even without the engagement of trigger 105.
Processor 121 may use user interface 124 to display relevant and/or important information to the user in real time. For example, processor 121 may present the amount and/or percentage of remaining power in power source 122, how many rounds were fired or are left, target status and/or present the preselected rules available and/or the chosen preselected rule and/or enable the user to reprogram the preselected rules. User interface 124 may also enable a user to input instructions into processor 121. For example, a user may use interface 124 to instruct processor 121 to lock and/or release the firearm by using a code, for example, face recognition, eye/retina and/or fingerprint identification, numerical and/or a sequence code, other mechanical or electronic locking features and/or a combination thereof. A user may also change the fire rate by selecting a new preselected rule and/or by manually adjusting the required fire rate. For example, a user may adjust the number of rounds fired per a single pull of the trigger and/or switch between different preselected rules as indicated above, such as FH or TH.
By integrating EMFC apparatus 100 to a mechanical firing mechanism of a firearm, a user may be able to control and/or reduce the firing rate of the firearm. Processor 121 may activate and/or deactivate electromagnet 125 or an equivalent electronically controlled actuator, to attract and/or repel movable plate 331, to cock and/or release a movable mechanical element participating in the firing process of the firearm, such as a trigger, a sear, a bolt carrier, a bolt carrier assembly, a hammer, a slider and/or a firing pin, as described later on, to match the required fire rate of the firearm. In some embodiments Electro Mechanical Energy Storing (EMES) mechanism 500 is configured to release and/or block at least one element, comprising the mechanical firing system of the firearm and participating in the firing process responsible directly or indirectly for firing a round in the firearm. For example, a trigger, a sear, a bolt carrier, a bolt carrier assembly, a hammer, a slider and/or a firing pin, as described later on, to match the required fire rate of the firearm. In some embodiments EMES 500 may be moved to a cocked position by at least one element, comprising the mechanical firing system of the firearm participating directly or indirectly in the cocking process of the firearm, upon firing the firearm or by manual operation for the firearm. For example, a trigger, a sear, a bolt carrier, a bolt carrier assembly, a hammer, a slider and/or a firing pin, as described later on, to match the required fire rate of the firearm.
According to some embodiments of the present disclosure, EMFC apparatus 100 may comprise a known Micro Electro Mechanical system (“MEMs”) unit 130, which may enable EMFC apparatus 100 to determine whether the firearm has deviated from its firing angle and/or direction, using for example a gyro and/or a sensor which may be configured to provide an indication in which angle and/or direction the firearm is positioned. Upon the received indication from MEMs 130, processor 121 may determine, for example that firearm 200 has deviated from its original and/or selected firing angle and/or direction more than a predetermined range. Processor 121 may then, for example prevent further firing of the firearm until trigger 105 is disengaged and/or the firearm is realigned with its original and/or acquired angle and/or direction.
Processor 121 may further be configured, for example by using interface 124 and/or communication unit 123, to enable firing only within predetermined boundaries. For example, a user may configure processor 121 to lock the firearm's firing mechanism when the direction of the barrel may be classified as an unsafe direction and/or deviation angle. For example, enabling the firing mechanism to fire within predetermined borderlines such as in a shooting range. Processor 121 may further disable the firing mechanism from firing, for example, when MEMs unit 130 detects that the direction, that the barrel of the firearm is pointed at, exceeds predetermined borderlines, which may be part of the preselected rules. It should be noted that the borderlines may vary from any of at least two points of an entire sphere, e.g. 360° vertical and 360° horizontal.
It should be noted that there may be more sensors configured to sending indications to processor 121 regarding the firearms status, than illustrated in the figures. For example: a sensor which is configured to provide an indication that a round was fired from the firearm; a sensor which is configured to provide an indication which mode is set and/or selected by the safety lever; a sensor which is configured to provide an indication which set of predefined rules were chosen; sensors which are configured to provide an indication in which state a hammer, a disconnector and/or a sear of the mechanical firing system are in; a sensor which is configured to provide an indication in which state a firing pin of the mechanical firing system is in; a sensor which is configured to provide an indication in which state a bolt carrier assembly of the mechanical firing system is in; a sensor which is configured to provide an indication if someone is physically holding the firearm i.e. if the firearm is being held or mounted or docked; a sensor which is configured to indicated the angle of the firearm i.e. provide an indication in what angle the firearm is positioned; a sensor which is configured to provide an indication if the firearm, a processor and/or another sensor is in sleep mode or not; a sensor which is configured to provide an indication of the time; a sensor which is configured to provide an indication of the remaining operation time, when using power consumption modes or features; a sensor which is configured to provide an indication that the system has acquired a target or still locked on a target, for example a target status; a sensor which is configured to provide an indication of the energy storing mechanism, and/or a sensor which is configured to provide an indication if the system is cocked or not; and a sensor configured to provide an indication of the temperature of an element of the firearm, for example a sensor configured to provide an indication of the temperature of the barrel of the firearm.

As described above processor 121 may activate and/or deactivate electromagnet 125. Processor 121 may use a circuitry (not shown) to generate a signal to control electromagnet 125. For example, the circuitry may convert a digital output of the processor 121 to an analog signal, thus enabling processor 121 to control the currents in the coils comprising electromagnet 125 (not shown). By controlling the currents in electromagnet 125, processor 121 may activate or deactivate the magnetic field generated and may control the force of the magnetic field and/or the direction of the magnetic field. Upon activation, electromagnet 125 may for example generate an electromagnetic force, which may be configured to repel movable plate 331. The electromagnetic force generated combined with the force of spring 333 may be sufficient to, for example overcome the force of magnet 332. By overcoming the force of magnet 332, second side of movable plate 331 may be released in a releasing energy phase. Second side of movable plate 331 may then, for example, be pulled back by spring 333. The releasement of second side of movable plate 331 may discharge the stored mechanical energy in spring 333 into a firing element in contact with movable plate 331, e.g. by using lever 522. The releasement of second face 342 of movable plate 331 from the surface of electromagnet 125 and/or magnet 332 may cause a consecutive firing of the firearm. Thereby enabling processor 121, using circuitry, to control electromagnet 125 and the firing of the firearm as detailed below.
Once the firing conditions have ended (as will be elaborated with respect to
In some embodiments, when mechanical energy is received, for example from at least one movable mechanical element during a firing of the firearm or by manual operation of the firearm, bar 352 may impart the energy to first face 340 of the movable plate 331. The imparted energy, i.e. force, may cause second face 342 of movable plate 331 to contact the surface of magnet 332 and/or electromagnet 125. When second face 342 of movable plate 331 is in contact with the surface of magnet 332 and/or electromagnet 125 it may cause spring 333 to store the imparted mechanical energy, for example, in a storing energy phase. When a destructive force is applied to the surface of magnet 332 and/or electromagnet 125 it may, damage the mechanism and/or one or more of the elements comprising it. In order to prevent damage to EMES mechanism 500 and/or the one of the elements comprising it, and thus to EMFC apparatus 100, in some embodiments, spring 334 and rod 354 may be added to the system. For example, spring 334 may connect movable plate 331 to bar 352 via rod 354. Spring 334 may be attached to movable plate 331 and be configured to prevent second face 342 of movable plate 331 from damaging the surface of magnet 332 and/or electromagnet 125. For example by absorbing some of the force applied on to bar 352 via rod 354. Therefore the force transferred to movable plate 331 may, be enough to cause movable plate 331 to connect to the surface of magnet 332 and/or electromagnet 125 but not enough to damage magnet 332, electromagnet 125, the apparatus and/or the elements comprising it. Spring 334 may, operate as a shock absorber, preventing movable plate 331 from impacting magnet 332 and/or electromagnet 125 with a destructive force which may cause breaking and/or damaging of magnet 332, electromagnet 125, movable plate 331 and/or the malfunction of EMES mechanism 500, and thus of EMFC apparatus 100. As illustrated in
As illustrated in
EMES mechanisms 510, 520 and 530 may be used to electronically control the fire rate of a firearm. Processor 121 may control the activation and/or deactivation of electromagnet 125. Movable mechanical elements participating in the firing process of the firearm such as a bolt carrier assembly and/or a slider may move back and forth when firing a round. Which may result, in the attachment of second face 342 of movable plate 331 to magnet 332 and the movement of first end 521 and second end 522 of sear lever 350 as described above. The movement of first end 521, when movable plate 331 is pushed towards magnet 332 and/or electromagnet 125, may enable cocking of hammer 210. It should be noted that the movement of any of the movable elements participating in the firing process of the firearm such as hammer, firing pin, trigger and/or sear and/or manual operation may also cause movable plate 331 to be pushed and/or attach to magnet 332. When a signal is received from processor 121 using a circuitry, electromagnet 125 may for example be activated, which may result in the releasement of movable plate 331 from magnet 332. When movable plate 331 is pulled back, e.g. away from magnet 332, by spring 333, spring 333 may discharge the stored mechanical energy it holds, into a firing element in contact with movable plate 331. For example, movable plate 331 may move on its way back first end 521 of sear lever 350, which may result in the movement of second end 522 and the releasement of hammer 210. Therefore processor 121, via electromagnet 125 and circuitry, may control the releasing intervals of hammer 210, slider 604 (as described later on) and/or other mechanical elements participating in the firing process of the firearm for example a sear, a bolt carrier, a bolt carrier assembly, a trigger and/or a firing pin, enabling processor 121 to control the fire rate. This is possible as long as the mechanical mechanism enables it, e.g. the trigger is pulled or engaged, the safety lever is set to the appropriate operation mode and the bolt carrier assembly and/or slider move back and forth cocking movable plate 331, hammer 210, firing pin (not shown) and/or other mechanical elements participating in the firing process of the firearm.
It should be noted that movable plate 331 may be comprised from a variety of different materials, shaped in a verity of forms that may possess magnetic or paramagnetic characteristics adapted to be pulled by a magnet and/or an electromagnet.
According to some embodiments of the present disclosure, EMES mechanism 500 may operate slightly different than described above. For example, EMES mechanism 500 e.g., any of mechanisms 510, 520 and/or 530 may not require magnet 332. For example, electromagnet 125 may operate constantly, upon activation, to attract movable plate 331 and upon receiving a signal from processor 121 it may deactivate, which may cause movable plate 331 to be pulled back by spring 333. Furthermore, EMES 500 may work the other way around e.g. spring 333 may be pushing movable plate 331. For example, movable plate 331 may be pushed by spring 333 towards magnet 332, magnet 332 may repel movable plate 331 and the force applied by electromagnet 125 may attract movable plate 331 and not repel it. Therefore, movable plate 331 may connect to and/or disconnect from magnet 332 according to the magnetic field applied by activating and/or deactivating electromagnet 125.

FD lever 370 may comprise at least one arm 371 pivotally mounted at fulcrum point 376 and may have at least one engaging point, e.g., engaging points 372, 374, and 378. In some embodiments, FD lever 370 may further comprise a slot, e.g., slot 379. For example, the slot, e.g., slot 379, and/or the at least one engaging point, such as engaging point 374, may be located on different ends of FD lever 370. In some embodiments, FD lever 370 may be shaped as the letter ‘F’, having one first arm, e.g., arm 371 and two second arms, e.g., arms 373 and 375. In some embodiments, first arm 371 is longer than each of second arms 373 and/or 375. The two second arms 373, 375 may include at least two engaging points, e.g., engaging point 372 and engaging point 374, such that each of the engaging points 372 and 374 may be located along one of the two short arms of the ‘F’ shaped FD lever 370. FD lever may be configured to pivot around a first mounting point 376 located along the at least first arm 371 to create a fulcrum. For example, first mounting point 376, may be located along the long arm 371 of the ‘F’ shaped FD lever 370, for example, between short arms 373 and 375 of the ‘F’ shaped FD lever 370 or at the meeting point of either of short arms 373 and 375 and long arm 371, in order to create a fulcrum. FD Lever 370 may be mounted at pivotal mounting point 376 to another FD lever located substantially on an opposite side of mechanism 540 and/or other element of EMFC apparatus 100, EMSE mechanism 500 and/or to an element of the firearm. FD lever 370 may be mounted by a pin, a screw, a nail and/or any other fastening means and/or methods enabling the mounting of elements with pivoting capabilities.
Additionally, FD lever 370 may comprise a slot, such as slot 379, which may be located along the long arm 371 of the ‘F’ shaped lever. FD lever 370 may slide and/or rotate around a certain point, e.g. second mounting point 378 via slot 379. Second mounting point 378 may be located along and on an opposite end of the long arm 371 of the ‘F’ shaped lever, i.e., opposite first mounting point 376. FD lever 370 may be mounted at second mounting point 378 to rod 354, first face 342 of movable plate 331, another lever substantially located on an opposite side of mechanism 540, and/or other element of EMFC apparatus 100, EMSE mechanism 500, and/or to an element of the firearm. Second mounting point 378 may be connected to one of the disclosed elements by, for example, a pin, a screw, a nail and/or any other fastening means and/or methods enabling sliding and/or rotating capabilities. FD lever 370 may slide along and/or rotate around second mounting point 378. The pin or any other fastening means and/or methods enabling sliding and/or rotating capabilities, may be configured to slide along slot 379 and enable FD lever 370 to rotate around it.
FD lever 370 may be engaged by bar 352, for example, via protrusion 380 and engaging point 372. FD lever 370 may be used to impart energy from bar 352 to rod 354, enabling rod 354 to receive lower energy than imparted onto bar 352, for example, by a mechanical element participating in the firing process of the firearm. Alternatively, in an energy storing phase, FD lever 370 may be engaged by bar 352, which may be pushed and/or pulled by spring 333, for example, via protrusion 380 and/or engaging point 374. By creating a fulcrum, FD lever 370 may enable magnet 332 and/or an electromagnet 125 to hold bar 352 in a static position, even though the force applied to bar 352 by, for example, spring 333 is greater than the holding force applied by magnet 332 and/or electromagnet 125. Thus, the fulcrum enables the use of a less powerful magnet and/or electromagnet than otherwise required. When mechanical energy is applied onto bar 352 it may in turn push FD lever 370, for example, via protrusion 380 which may engage engaging point 372. When force is applied to FD lever 370, for example, by bar 352 via protrusion 380 and/or engaging point 372, FD lever 370 may pivot around first mounting point 376. For example, FD lever 370 may pivot around first mounting point 376, toward magnet 332 and/or electromagnet 125, e.g., FD lever 370 may rotate clockwise, imparting energy to rod 354. Rod 354 may in turn push movable plate 331 toward magnet 332 and/or electromagnet 125, as illustrated in
When second face 342 of movable plate 331 is connected to the surface of magnet 332 and/or electromagnet 125, spring 333 may apply force to bar 352 pushing and/or pulling bar 352. For example, spring 333 may push and/or pull bar 352 away from magnet 332 and/or electromagnet 125. When force is applied by spring 333 to bar 352, protrusion 380 may in turn engage and apply force to FD lever 370 via engaging point 374. Magnet 332 and/or electromagnet 125, which hold plate 331 in contact with the surface of magnet 332 and/or electromagnet 125, may consequently hold rod 354 in a static position. When rod 354 is being held in a static position as described above, it may in turn prevent FD lever 370 from pivoting. For example, preventing FD lever 370 from pivoting around first mounting point 376, such as away from magnet 332 and/or electromagnet 125, e.g., rotating FD lever 370 counter clockwise. When FD lever 370 is being held in a static position, for example, by rod 354 and/or movable plate 331, as described above, and when spring 333 applies force, for example, onto bar 352, protrusion 380 may engage engaging point 374. When FD lever 370 is being held in a static position, engaging point 374 may also hold bar 352, via protrusion 380, in a static position, overcoming the force applied by spring 333. Magnet 332 and/or electromagnet 125, which hold movable plate 331 in contact with the surface of electromagnet 125 may thus hold bar 352 in a cocked position. That is, the holding force applied by magnet 332 and/or electromagnet 125 by implementing the configuration of FD lever 370 and/or rod 354 may overcome the force applied by spring 333, as described above. Holding bar 352 in a cocked position i.e., overcoming the force of spring 333, may be possible due to the fulcrum and/or the levers created by the design of FD lever 370. As a result of the shape of FD lever 370 and the location of first mounting point 376 that creates the fulcrum, the holding force applied to bar 352, for example, by magnet 332 and/or electromagnet 125, may be enhanced. The enhancement of the holding force applied onto bar 352 may be related to the length of arms of FD lever 370 long arm 371 and either of short arm 373 and/or arm 375 of FD lever 370. For example, the length of a lever (which may be equivalent to the length of the long arm 371 of FD lever 370) may be defined by the distance created between the meeting point of long arm 371 and one of the short arms, such as short arm 375, and second mounting point 378 of FD lever 370.
According to some embodiments, in order to further reduce the force applied to rod 354 by the mechanical energy, as described above, and to synchronize the motion of rod 354 with the motion of bar 352, spring 335 may be added to the system. For example, spring 335 may have a fixed first end and a second end connected to rod 354, which may be configured to apply force in an opposite direction from the force applied by magnet 332 and/or electromagnet 125, e.g., pulling and/or pushing rod 354 towards and/or away, magnet 332 and/or electromagnet 125.
Consequently, magnet 332 and/or electromagnet 125 may be required to apply a holding force strong enough to overcome the reduced force applied by spring 333 and the force applied by spring 335. The force applied by magnet 332 and/or electromagnet 125 may be required to overcome the force of spring 333, while incorporating the principle of moments, as illustrated in equation (1):
Wherein: Fs1 denotes the force applied by spring 333; Fm denotes the holding force applied by magnet 332 and/or electromagnet 125; l1 denotes the length of long arm 371, i.e., the distance created between first mounting point 376 and second mounting point 378; Fs2 denotes the force applied by spring 335 and/or spring 334; l2 denotes the length of short arm 375, for example, the distance created between the meeting point of both short arm 375 and long arm 371 and engaging point 374.
According to equation (1) incorporating a lever, e.g., FD lever 370 into mechanism 500, e.g., mechanism 540, enables use of a more powerful spring 333 to be held in an energy storing phase without the need of using a more powerful magnet 332 and/or electromagnet 125, as would otherwise be required in case no lever was implemented in mechanism 540. That is, a lever enables reduction of the force of spring 333 projected onto magnet 332 and/or electromagnet 125.
It should be understood that an FD lever may be comprised of a variety of different materials, for example, metal, plastic, carbon fibers, polymer, composite materials and/or any combination thereof. FD lever may be shaped in different forms, for example, one lever comprising two mounting points located in two slots at opposite ends of the lever, an “L” shaped lever having only one short arm and one long arm, a piston, a spring or any other system and/or element enabling the reduction and/or the enhancement of energy and/or force, and/or any element capable of forwarding a reduced and/or an enhanced force as a result of force applied thereon.
In some embodiments, FD lever 370 may pivot around a pivotal point, which may be located in substantially any location within the firearm system. This may enable the designer of the firearm to locate the FD system in a plurality of possible locations, not limited to a specific location along the EMFC apparatus. For example, the pivotal point may be an external pivoting point, located on an external pivoting axis, which may be located externally to FD lever 370, e.g., not located along long arm 371. FD lever 370 may pivot around such external pivoting axis, to create a fulcrum.

The force causing sear lever 350 to pivot, originates from the complete motion range of bar 352, when pushed by spring 333. Since bar 352 may be blocked by pusher 612, it may not be able to reach the end of its stroke e.g. move its designated distance towards the rear of the firearm. Thus, bar 352 may not be able to fully push sear lever 350 to complete the pivoting of sear lever 350 around pin 616 and pivot sear 602. Therefore, by blocking bar 352 from reaching the end of its stroke, pusher 612 may prevent, via bar 352 and sear lever 350, sear 602 from pivoting and releasing slider 604, until the trigger is released and the system may be restarted. When bar 352 is blocked, it may not be able to pivot sear lever 350, which then may not be able to pivot sear 602, which may enable the releasement of slider 604. Therefore, as described above, when a malfunction of the EMES mechanism occurs, bar 352 may be blocked by pusher 612, which may prevent the malfunctioned EMES mechanism from free firing the firearm, as long as the trigger is engaged. However, when the trigger is disengaged the system may be restarted. As described above, when there is a malfunction of the EMFC apparatus the firearm may be able to fire only one round at a time when using the EMFC mode, which may be the first round fired using the mechanical firing mechanism of the firearm.
It should be noted that when the safety lever is switched to an automatic firing mode, the firearm will be able to fire at its original automatic fire rate using solely the mechanical firing mechanism.

As indicated in block 806, processor 121 may detect that trigger 105 is engaged, for example via sensor 110. Upon receiving indication from sensor 110 that the trigger was engaged, processor 121 may activate the EMFC rules that were selected. If processor 121 had gone into a sleep mode, upon receiving indication from sensor 110 that the trigger was engaged, processor 121 may exit the sleep mode and may activate the EMFC rules that were selected. As indicated in block 808, processor 121 may detect, for example using a firing sensor, that a round was fired, which may be, for example, the first round of a firing session. Upon receiving indication form the firing sensor, processor 121 may activate the EMFC rules that were selected. As indicated in block 810 once processor 121 may receive indication that the trigger is engaged, it may instruct electromagnet 125 to activate and/or deactivate, according to the preselected rule. For example, processor 121 may detect which preselected rule was chosen by the user, for example according to the mode of operation the safety lever is set to. After detecting the preselected rules, processor 121 may then activate and/or deactivate electromagnet 125 to hold or release movable plate 331 to control the fire rate. For example, according to the required RPM and/or the number of rounds fired during the firing session and/or the total number of rounds fired for a preselected time period.
As indicated in block 812, after and/or before every round fired processor 121 may check for compliance of the firing conditions and/or rules. For example a rule may me be a total of number of rounds fired while the trigger is engaged. Therefore, if the total number of rounds fired meets the number of rounds determined in the preselected rules, as long as the trigger is engaged, than processor 121 may instruct electromagnet 125 to activate and/or deactivate in order to stop firing the firearm. Another example may be that processor 121 may stop the firearm from firing after five consecutive rounds were fired according to a preselected rule. In another case, processor 121 may determine, for example, that the end of firing condition is when the firearm has deviated from a target direction and/or angle. For example, MEMs unit 130, may be used to determine a direction at which the firearm is directed. If for example, MEMs unit 130 measures that the firearm has deviated from its direction and/or angle, processor 121 may cease further firing from the firearm, until the trigger is released. In Another example, the end of firing condition may be that the trigger is no longer engaged resulting in stopping firing from the firearm, for example, a user may remove his or her finger from trigger 105. Processor 121 may receive an indication from trigger sensor 110 that the trigger is no longer in an active state, thus resulting in ending of the firing session. If the fire rate rules and conditions are met processor 121 will continue to instruct electromagnet 125 to activate and/or deactivate the electromagnet to continue firing according to the preselected rules and firing conditions. However, if the firing rules are not met, for example, the trigger is no longer engaged, then according to block 814 processor 121 may activate or deactivate electromagnet 125 in a manner that will stop the use of EMFC 100, thereby stopping the firearm from firing another round, consequently ending the firing session and resetting the system to enable it to enter a new firing session.

As indicated in block 906, mechanical energy generated by at least one mechanical element participating in the firing processes and/or cocking of a firearm may be stored by the EMFC apparatus. When the safety lever is switched to an Electro Mechanic Fire Control mode, the EMFC apparatus may be activated, e.g. start to control the stored mechanical energy. The stored mechanical energy may be produced by a mechanical element, for example, a mechanical element participating in the firing process and/or cocking of the firearm and/or by manual operation of the firearm. In some embodiments, the apparatus may store mechanical energy, for example by using the mechanical energy generated from the previous fire round and/or manual operation of the weapon, prior to switching the safety lever to an Electro Mechanic Regulated Fire mode, i.e. block 906 may be performed prior to block 904.
As indicated in block 908, the EMFC apparatus may control the Electro Mechanical Energy Storing (EMES) mechanism. For example, the EMFS mechanism may use an electromagnet to hold and/or release the mechanical energy stored. The stored mechanical energy may be produced when, for example, firing and/or by manual operation of the firearm. Controlling the energy storing mechanism may result in activating and/or deactivating electromagnet 125. Activating and/or deactivating electromagnet 125 may enable and/or prevent the firearm from firing, which may enable the EMFC apparatus to control the fire rate. Controlling the fire rate may be subject to preselected rule. For example, processor 121 may detect which preselected rule was chosen by the user, for example according to the mode of operation the safety lever is set to. After detecting the preselected rules, processor 121 may then activate and/or deactivate electromagnet 125 to hold or release movable plate 331 to control the fire rate. For example, according to the required RPM and/or the number of rounds fired during the firing session and/or the total number of rounds fired for a preselected time period.
As indicated in block 910, after and/or before every round fired processor 121 may check for compliance of the firing conditions and/or rules. For example a rule may me be a total of number of rounds fired while the trigger is engaged. Therefore, if the total number of rounds fired meets the number of rounds determined in the preselected rules, as long as the trigger is engaged, processor 121 may instruct electromagnet 125 to activate and/or deactivate in order to stop firing the firearm. Another example may be that processor 121 may stop the firearm from firing after five consecutive rounds were fired according to a preselected rule. In another case, processor 121 may determine for example that the end of firing condition is when the firearm has deviated from a certain direction and/or angle. For example, MEMs unit 130, may be used to determine a direction at which the firearm is directed. If for example, when MEMs unit 130 measures that the firearm has deviated from a desired direction and/or angle, processor 121 may cease further firing from the firearm, until the trigger is released. In Another example, the end of firing condition may be that the trigger is no longer engaged resulting in stopping the firearm from firing, for example, a user may no longer engage trigger 105. Processor 121 may receive an indication from trigger sensor 110 that the trigger is no longer engaged, thus resulting in ending of the firing session. If the fire rate rules and conditions are met processor 121 will operate electromagnet 125 to continue firing according to the preselected rules and firing conditions. However, if the firing rules are not met, than according to block 912 processor 121 may stop the operation of electromagnet 125 in order to stop the firearm, from firing another round using the EMFC mode, and consequently ending the firing session and resetting the system to enable it to enter a new firing session.
