Description

DRY FIRE PRACTICE AND TRAINING MAGAZINE DEVICE WITH ARTICULATING LEVER HEADCROSS-REFERENCE TO RELATED APPLICATION S)(0001 | This application claims priority to U. S. Provisional Patent Application Serial No.63 / 716,385 that was filed on 5 November 2024 entitled “DRY FIRE PRACTICE AND TRAINING MAGAZINE DEVICE WITH ARTICULATING LEVER HEAD,” the entire contents and disclosure thereof is fully incorporated by this reference as if fully restated herein.FIELD(0002] The present application relates to firearms and more particularly to dry fire practice and training magazines for firearms.BACKGROUND(0003] Live fire (using live ammunition) is essential to practice drawing and firing a weapon and historically has been the primary method of training with firearms. The practice process builds muscle memory, and helps the shooter develop proper techniques of delivery and complete weapon control. There are several negatives of this type of practice. Using ammunition is an ongoing expense, and measures have to be taken to practice with safety. This could mean traveling to a firing range, providing safety equipment for the shooter and possibly others, and allotting special time in the schedule for the practice session.|0004] More recently, experts have recognized that dry fire practice (practicing without live ammunition) is an essential addition for live fire practice to be successful and effective. Dry firing is another process of building muscle memory whereby a firearm, especially a pistol or handgun, is drawn, aimed, and fired without using live ammunition. This enables the practice of firing a weapon to proceed smoothly and accurately without all of the negatives of live fire practice.Because no live ammunition is used, there is no ongoing expense, there is no need to use safety equipment, a special shooting environment is not necessary, and practicing can be accomplished in much less time.00O5| Dry firing also allows the shooter to practice in the actual environment where the weapon may need to be used for protection such as in the home. With complete safety, actual shooting scenarios can be practiced in and around the home.|0006| Practicing at the range can also be improved. When live fire is practiced at the range, the novice shooter usually has to spend a significant amount of time and expend a lot of ammunition getting accustomed to the report and recoil of the pistol. Before live practice begins, some dry fire practicing can be done. This gets the shooter accustomed to the trigger feel before having to deal with the recoil and the report of live firing.O0O7| One negative factor with most methods of dry firing occurs because when a semiautomatic pistol is live fired, the live firing resets the firing pin and / or trigger mechanism and the firearm is ready to be fired again immediately until the magazine is empty. The shooter's hands remain in the firing position, and just the trigger finger and the trigger mechanism are employed. With normal dry fire practice, after the first activation of the trigger mechanism releasing the firing pin, the shooter must remove a hand from the pistol, and “rack” the slide back in order to reset the firing pin and to return the trigger mechanism and firing pin to an unfired position. The pistol is then ready for another activation. This must be done each time a shot is simulated. Doing this teaches improper muscle memory because it is not at all what happens during actual live fire. When people are in real shooting situations, they need to be able to depend on simply acting upon how they have practiced. Anything else could be deadly and some situations have proven catastrophic.0008| Another negative for standard dry fire practice is wear and tear caused by repeated releasing of a weapon's firing pin without having the cushioning effect of the firing pin striking a round of ammunition.O000| Another shortcoming of dry fire practice activities is that it does not adequately train the user to reload or swap an empty magazine for a full magazine. The dry fire training magazines known prior to the present invention do not release from the magazine well of the firearm in the same manner and motion as live fire magazines. Users who practice and train with dry fire training magazines do not develop the muscle memory and habit associated with releasing an empty magazine and replacing the empty magazine with a full magazine because the actions, motions, and muscle movements associated with the dry fire training magazine are too different from those associated with live fire magazines.Some firearm training systems incorporate computer graphics into the training scenario. Other patents address the duplication of a pistol's recoil, laser marking of "shots", projecting images onto a screen, etc.[00111 Further drawbacks of known devices and systems are that such devices / systems are user intensive and / or expensive to purchase, and significantly do not allow a shooter to use a fully functioning pistol that may already be owned. There is also a learning curve and training necessary to use such devices / systems. Known dry fire practice devices, such as those disclosed at U. S. Pat. Nos. 9,182,189 and 11,460,271 and international PCT patent application numbers PCT / US2024 / 021924 and PCT / US2025 / 012374 resolve various of these drawbacks including, but not limited to, resolving the "hands-free" trigger mechanism reset problem and the possible firing pin damage problem of normal dry fire practice. The entirety of U. S. Pat. Nos. 9,182,189 and11,460,271 and international PCT patent application numbers PCT / US2024 / 021924 and PCT / US2025 / 012374 are incorporated by reference in their entireties, as if fully restated herein.

[0001] Previous versions of the dry fire practice device, such as those disclosed at U. S. Pat. Nos. 9,182,189 and 11,460,271, included a swing lock configured to interact with a member in the pistol’s magazine well to lift and place the lever in the proper position with respect to the pistol’s trigger mechanism when the device is inserted into the pistol’s magazine well. The swing lock was discovered to have drawbacks when used with some smaller models of firearms in that it would catch in the magazine well of some pistols causing unnecessary wear and tear. In some examples, the swing lock unnecessarily scored the pistol’s magazine well after repeated use. A further drawback was the swing lock included additional moving parts that created an additional possible point-of-failure. Furthermore, due to the configuration of the swing lock, it was necessarily narrower than the lever. It was discovered that the swing lock was potentially problematic when the user desired the swing lock to be as wide as or wider than the lever. An improved dry fire training device with a fixed or integrally molded trigger bias component was disclosed in U. S. provisional patent application serial number 63 / 456,279 and international PCT patent application number PCT / US2024 / 021924. The entirety ofU. S. Pat. Nos. 9,182,189 and 11,460,271 and U. S. provisional patent application serial number 63 / 456,279 and international PCT patent application number PCT / US2024 / 021924 are incorporated by reference in their entireties, as if fully restated herein.[0013| Previous versions of the dry fire practice device improved the ability of the device to drop freely from the magazine well of the firearm when the magazine retention is released by eliminating the integrally molded trigger bias and including an articulating lever head that is functionally engaged with a plunger such that when the device is fully inserted into the magazinewell of the firearm, the plunger frictionally engages with the interior surface of the magazine well and the lever head rotates into a protruding position and the lever is appropriately positioned behind the trigger mechanism, and when the magazine retention is released, the spring-biased plunger ejects the device from the magazine well of the firearm and the lever head rotates to a retracted position within the device. An example of one such improved version of the dry fire practice device was disclosed in U. S. provisional patent application serial number 63 / 623,157 and international PCT patent application number PCT / US2025 / 012374. The entirety of U. S. provisional patent application serial number 63 / 623,157 and international PCT patent application number PCT / US2025 / 012374 are incorporated by reference in their entireties, as if fully restated herein.There is a remaining need for further improved dry fire training devices for use with fully functioning firearms, that allow for precise muscle memory training, are simple to operate, prevent the firing pin of the fully functioning firearm from being damaged, provide for safe onsite home training, insert easily into the magazine well of the fully functioning firearm, have capabilities to interact with a variety of other functional and / or training systems, and have the ability to drop freely when the magazine retention is released. The present application improves upon U. S. Pat. Nos. 9,182,189 and 11,460,271 and international PCT patent application numbers PCT / US2024 / 021924 and PCT / US2025 / 012374.|0015] Persons having ordinary skill in the art will readily recognize that different manufacturers and models of firearms include various different parts and components in their respective trigger mechanisms. Throughout this disclosure, the term “trigger mechanism” refers to and includes any part of the trigger assembly from the trigger through the striker, firing pin, hammer, or similar structure.SUMMARY(0016] According to one aspect, a dry fire training device is designed for use with a fully functional firearm with a trigger mechanism. In some embodiments, the dry fire training device includes a rigid outer case. The rigid outer case is designed to engage with the magazine slot or well of the firearm. In some embodiments, the dry fire training device includes a rigid outer case of a standard OEM magazine or other comparable magazine outer case. In some other embodiments, the dry fire training device does not include a rigid outer case. In some embodiments, the dry fire training device includes an insert designed to fit within a rigid outer case of a standard OEM magazine or other comparable magazine outer case with minimal modifications.0017] Within the rigid outer case or within the insert is a lever. The lever is configured to move between two positions - a first position and a second position. The lever is biased toward the first position. The lever includes a top end portion that protrudes out of the outer case or insert. In some embodiments, a lever head is attached to the top end of the lever and the lever head is sized and shaped to position the lever behind the trigger mechanism and in the first position. In some embodiments, the lever includes a trigger bias component or protrusion. The trigger bias protrusion is a molded part of the lever or otherwise fixedly attached to the lever. The trigger bias protrusion is configured such that when the rigid outer case is inserted into the magazine well of the firearm, the trigger bias protrusion frictionally engages with the interior surface of the magazine well and pushes the lever backward and positions the lever behind the trigger mechanism and in the first position. When the trigger mechanism is pulled, the trigger mechanism pushes the lever toward the second position. When the trigger mechanism is released, the lever returns toward the first position and pushes and / or follows the trigger mechanism back toward its originalposition, ready to fire again. In some embodiments, also within the outer case or insert is a detent reed connected to the lever. The detent reed provides tactile and audible feedback every time the trigger mechanism is pulled and the lever moves between positions. In some embodiments, the device includes a compression spring functionally situated between the lever and the outer case to bias the lever toward the first position.(0018] In some embodiments, the device includes an insert arm connected to the lever. In some embodiments, the insert arm is sized and shaped such that the insert arm and lever fit within the insert. In some other embodiments, the insert arm is sized and shaped such that the insert arm and lever fit within the rigid outer case. In some embodiments, the device includes a compression spring functionally situated between the lever and the insert arm to bias the lever toward the first position. In some embodiments, the device includes a detent reed functionally situated between the lever and the insert arm to bias the lever toward the first position and to provide tactile and audible feedback every time the trigger mechanism is pulled. In some embodiments, the lever includes a trigger bias component or protrusion. The trigger bias protrusion is a molded part of the lever or otherwise fixedly attached to the lever. The trigger bias protrusion is configured such that when the rigid outer case is inserted into the magazine well of the firearm, the trigger bias protrusion frictionally engages with the interior surface of the magazine well and the lever is positioned functionally relative to the trigger mechanism and with the lever biased toward the first position.(0019| In some optional embodiments, the dry fire training device also includes a plunger. The plunger is configured to slide between two positions - a protruding position, with at least a portion of the plunger protruding outside the outer case, and a retracted position, with at least a portion of the plunger retracted within the outer case. The plunger is spring biased toward the protrudingposition. The plunger is configured such that when the rigid outer case is inserted into the magazine well of the firearm, the plunger frictionally engages with the interior surface of the firearm and slides to the retracted position. When the firearm’s magazine retainer is released, the spring biased plunger returns toward its protruding position, which also tends to assist with ejecting the training device from the magazine well. The device is then free to drop away from the magazine well without significant frictional resistance. Unlike in previous versions, in the present version of the invention, the movement of the lever and the sliding of the plunger are independent of each other. J0020J According to another aspect, a method of manufacturing a dry fire training device, designed for use with a fully functional firearm with a trigger mechanism, includes providing a rigid outer case. The rigid outer case is designed to engage with the magazine well of the firearm. Within the outer case a lever is arranged to move between two positions - a first position and a second position. The lever is biased toward the first position. The lever includes a top end that protrudes out of the outer case. In some embodiments, an articulating lever head is attached to the top end of the lever and the articulating lever head is sized and shaped to position the lever behind the trigger mechanism and in the first position. When the trigger mechanism is pulled, the trigger mechanism pushes the lever toward the second position. When the trigger mechanism is released, the lever returns toward the first position and pushes and / or follows the trigger mechanism back toward its original position, ready to fire again.|O02.1| According to another aspect, another method of manufacturing a dry fire training device is provided.

Fig. 11 is a cross-sectional view of the dry fire training device along line A-A shown in Fig. 9. Fig. 12 is a cross-sectional view of the dry fire training device along line C-C shown in Fig. 10.|0074| Fig. 13 is an exploded perspective view of the dry fire training device 10. The dry fire training device 10 includes a rigid outer case comprised of two opposing sides 101 and 102. Within the outer case is a lever 104. As shown in Fig. 13, the lever 104 is configured to pivot between two positions - a first position and a second position. The lever 104 is biased toward the first position. In Fig. 13, the lever 104 includes an articulating lever head 120. The lever head 120 is sized and shaped such that when the rigid outer case is fully inserted into the magazine well of the firearm, at least a portion of the lever head 120 protrudes outwardly from the exterior surface of the rigid outer case and positions the lever 104 behind the trigger mechanism and in the first position. In the embodiment shown in Fig. 13, the lever head 120 is attached to the lever 104 via a pivot pointand is configured to rock between a first position and a second position, and is spring biased toward the first position. Fig. 30 shows the lever head 120 in the first position. Fig. 31 shows the lever head 120 between the first position and the second position. Fig. 32 shows the lever head 120 in the second position. In some embodiments (not shown), the lever 104 is configured to move in a sliding manner, non-pivotally, between the two positions - the first position and the second position.

[0075] In some embodiments (not shown), the lever 104 includes a trigger bias protrusion (not shown). The trigger bias protrusion is sized and shaped such that when the rigid outer case is inserted into the magazine well of the firearm, the trigger bias protrusion frictionally engages with the interior surface of the magazine well and pushes the lever 104 rearward and positions the lever 104 functionally relative to the trigger mechanism. In some embodiments, the trigger bias protrusion is configured to be non-moveable or fixed relative to the lever 104. In some other embodiments, the trigger bias protrusion is configured to be moveable or pivotable relative to the lever 104. In some embodiments, the trigger bias protrusion is a molded and integral part of the lever 104. In some embodiments, the trigger bias protrusion is fixedly attached to the lever 104.When the trigger mechanism is pulled the trigger mechanism pushes the lever 104 toward the second position. When the trigger mechanism is released, the lever 104 returns toward its first position and pushes and / or follows the trigger mechanism back, ready to fire again. Fig.27 shows the top of the lever 104 in the first position. Fig. 28 shows the top of the lever 104 at a point between the first position and the second position. Fig. 29 shows the top of the lever 104 in the second position.0077) The lever 104 is shown in greater detail at Figs. 14-17. The top portion of the lever 104 is sized and shaped such that when the training device 10 is inserted into the magazine well of thefirearm, the top portion of the lever 104 and / or the lever head 120 frictionally engages with the trigger mechanism of the firearm so as to properly position the top portion of the lever 104 or the lever head 120 to interact with the firearm trigger mechanism for operation.(0078| In some embodiments (not shown), a shim or spacer is positioned between the lever 104 and the outer case (101 and 102). In some embodiments, the shim or spacer is sized, shaped and configured to move relative to the outer case to help position a portion of the lever 104 to functionally interact with the trigger mechanism. In some embodiments, the shim or spacer is fixed in place relative to the outer case. In some embodiments, the shim or spacer is fixed in place relative to the lever 104. In some embodiments, the shim or spacer is removable from the dry fire training device. In some embodiments, a set screw is positioned between the lever 104 and the outer case, sized, shaped and configured to position a portion of the lever 104 to functionally interact with the trigger mechanism.As shown in Fig. 13, within the outer case (101 and 102) is a detent reed 111 connected to the lever 104. The detent reed 111 provides tactile and audible feedback every time the trigger mechanism is pulled and the lever 104 is moved between positions. In some embodiments, the detent reed Ill is lodged against the interior surface of the outer case. In some other embodiments, the detent reed 111 rests against a regulating set screw 109. In some embodiments, the detent reed 111 is configured to bias the lever 104 toward the first position. In some embodiments, the detent reed 111 is positioned between the outer case and the lever 104. In some embodiments, the detent reed 111 is positioned between the insert and the lever 104. In some embodiments (not shown), the device 10 does not include the detent reed 111.(0080] In some embodiments, such as that shown in Fig. 13, the device 10 includes a compression spring 110 functionally situated between the lever 104 and the outer case (101 and102) to bias the lever 104 toward the first position. In some embodiments (not shown), the compression spring 110 is functionally situated between the lever 104 and the outer case to bias the lever 104 toward the first position, without any detent reed. In some embodiments (not shown), the device 10 does not include the compression spring 110.

[0081] Still referring to Fig. 13, the outer case of the dry fire training device 10 is formed when opposing sides 101 and 102 are connected to one another using screws or adhesive. The outer case shown in Fig. 13 has a top end portion, a bottom end portion, a front portion, a back portion, two opposing side portions, an exterior surface and an interior cavity. The interior cavity of the outer case has inside surfaces at the top end portion, the bottom end portion, the front portion, the back portion, and the two opposing side portions 101 and 102. The outer case also has a platform, projection, or other surface at the inside top end portion for engagement with the compression spring 110.As shown in Fig. 13, the lever 104 is pivotably carried within the interior cavity of the rigid outer case. The lever 104 is elongate and has a bottom end portion that is proximate the inside bottom surface of the interior cavity of the outer case. The lever 104 also has a top end portion that is proximate the top end portion of the rigid outer case. Depending on the structure of the specific firearm, either the lever head 120 or the lever 104 includes a projection sized and shaped to engage with the trigger mechanism of the firearm. In some embodiments, the lever head 120 or the lever 104 also includes a platform, projection, or other surface for engagement with the compression spring 110. According to the embodiment shown in Fig. 13, the lever 104 pivots on a fulcrum within the outer case, preferably connected between the two opposing side portions 101 and 102. In some embodiments (not shown), the lever 104 slides or otherwise moves relative to the outer case, rather than pivoting about a pivot point.

[0083] In the embodiment shown in Fig. 13, the dry fire device 10 also includes a plunger 116 and a plunger spring 118 attached to the plunger 116. The plunger 116 is sized and shaped to actuate between a retracted position and a protruding position. The plunger spring 118 biases the plunger 116 toward the protruding position. The plunger 116 is sized and shaped to engage with the interior surface of the magazine well of the firearm, or other similar structure, when the dry fire training device 10 is inserted within the magazine well. When the dry fire training device 10 is fully inserted within the magazine well, the plunger is actuated to its retracted position. The plunger 116 and the lever 104 are configured such that the plunger 116 actuates separately and independently of any movement of the lever 104 and the lever head 120. The plunger 116 is optional and persons of ordinary skill in the art will appreciate that the plunger 116 is readily omitted from the invention in other embodiments (not shown).Still referring to Fig. 13, the detent reed 111 is connected to the lever 104 at one end and adjacent the inside back surface of the rigid outer case at the other end. The detent reed Ill is formed of a material that generates a tactile and audible signal when manipulated through an activation point between an un-tripped position and a tripped position. In some embodiments, the end of the detent reed 111 opposite the lever 104 rests against a regulating set screw 109. The regulating set screw 109 operatively communicates with the detent reed 111 to provide adjustability to the activation point of the detent reed 111. This makes the tactile and audible feedback of the detent reed 111 adjustable. The detent reed 111 is configured to interact with the lever 104 to provide audible and tactile feedback when the lever 104 is moved between the first position and the second position. In some embodiments, the detent reed Ill is configured to bias the lever 104 toward the first position.

[0085] In some embodiments, such as that shown in Fig. 13, the training device 10 also includes a microprocessor on a printed circuit board 105 within and connected to the outer case. The microprocessor is connected to a microswitch that is activated when the lever 104 is actuated from the first position toward the second position. The microprocessor sends a signal when the microswitch is activated. In some embodiments (not shown), the signal activates an LED. The microprocessor and LED are powered by a battery located within the rigid outer case. In some embodiments (not shown), the signal sent by the microprocessor when the microswitch is activated is infrared. In some embodiments (not shown), the signal sent by the microprocessor when the microswitch is activated is visible light. In some embodiments (not shown), the signal sent by the microprocessor when the microswitch is activated is Bluetooth. In some embodiments (not shown), the signal sent by the microprocessor when the microswitch is activated is sound. In some embodiments (not shown), the signal sent by the microprocessor when the microswitch is activated is vibration. In some embodiments, the lever 104 includes a microswitch activation screw. The microswitch activation screw operably connects the lever 104 to the microswitch to send the signal when the microswitch is activated. Persons having ordinary skill in the art will appreciate that the configuration of the microswitch, the microprocessor, and the lever 104 can be arranged in many different functional configurations.In some embodiments, the signal is configured to interact with various electronic components to allow the dry fire training device to function with and operatively communicate with other training devices, such as, but not limited to laser training devices, computer targeting systems, and computer training systems. The various electronic components and other training devices may be positioned within the barrel of the firearm, connected to a firearm accessory mounting platform, or otherwise external to the dry fire training device. The various electroniccomponents and other training devices may include laser light sources, light emitting diodes, a power source such as a battery or a capacitor, circuit boards or other electronic circuitry, microswitches, transmitters, receivers, transceivers, and the like.The embodiment shown in Fig. 13 also includes weights 112 such that the total weight of the training device 10 more closely approximates the weight of a magazine filled with live ammunition to give the device 10 a more realistic feel. Persons having ordinary skill in the art will appreciate that weights 112 are optional and can be optimized according to user preference.0088j In some embodiments (not shown), the device 10 also includes an attachment interface configured to engage with a firearm accessory mounting platform, such as (but not limited to) the Picatinny rail system. Persons having ordinary skill in the art will appreciate that the attachment interface can be designed to engage with virtually any firearm accessory mounting platform.Figs. 18, 19, and 20 show various different views of the plunger 116 of the dry fire training device 10 shown in the Figs. Fig. 18 is a perspective view of the plunger 116. Fig. 19 is a side view of the plunger 116. Fig. 20 is a front view of the plunger 116.

[0090] Figs. 24, 25, and 26 show various different views of the plunger 116 of the dry fire training device 10 shown in the Figs. Fig. 24 is the front view shown in Fig. 6, with the plunger 116 shown in the spring biased protruding position. Fig. 25 is the front view shown in Fig. 6, with the plunger 116 shown between the protruding position and the retracted position. Fig. 26 is the front view shown in Fig. 6, with the plunger 116 shown in the retracted position. The plunger 116 in the retracted position can be caused to occur when the dry fire training device 10 is fully inserted within the magazine well of the firearm. The plunger 116 in the spring biased protruding position can be caused to occur when the dry fire training device 10 is not within the magazine well of the firearm. The plunger 116 being spring biased toward the protruding position causes the plunger116 to aid in ejection of the dry fire training device 10 when the magazine retention is released. The dry fire training device 10 will drop free of the magazine well with minimal gravity assistance. As the dry fire training device 10 is inserted into the magazine well of the firearm to the point where the plunger 116 first begins to engaged, or if the plunger 116 is manually engaged outside of the magazine well of the firearm, the plunger 116 begins to actuate away from the protruding position and toward the retracted position. When the dry fire training device 10 is fully inserted into the magazine well, or if the plunger 116 is manually engaged outside of the magazine well, the plunger 116 becomes fully actuated to the retracted position.

[0091] In most firearms, a retainer holds the magazine in place when it is fully inserted into the magazine well. The dry fire training device 10 is configured such that the firearm’s retainer will also hold the dry fire training device 10 in place when it is fully inserted into the magazine well. When the retainer is released, the dry fire training device 10 of the present invention will drop free just like a live fire magazine will drop free from the magazine well.

[0092] Referring to Figs. 33-43, another embodiment of the dry fire training device 10 is shown. The dry fire training device 10 includes a rigid outer case 100.
