Abstract
When a semi-automatic weapon is live fired, it's firing pin is reset, and it is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. With dry fire practice, the shooter must manually rack the slide to reset the firing pin, allowing the trigger to return to its unfired position each time a shot is simulated. This invention provides, realistic muscle memory training by duplicating the action of the trigger in normal live fire, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activation. The invention further provides components that allow use with other electronic training devices such as lasers, video simulators, and virtual reality.

DETAILED DESCRIPTION OF THE INVENTION
[0044] FIG. 1 illustrates a back view of the exterior of a simulated magazine case 1. FIG. 2 illustrates a sectional side view of the simulated magazine case 1 along the sectional line 2-2 shown in FIG. 1. FIGS. 1 & 2 illustrate the simulated magazine case 1 that has six holes. The simulated magazine case 1 includes a pair of opposing holes, one in each side of the simulated magazine case 1 (indicated as 14 in FIG. 2). In combination, this pair of opposing holes 14, one in each side of the simulated magazine case 1, are sized and shaped to receive the fulcrum pin 7 (shown in FIG. 19) for the lever 2 (shown in FIG. 19) to hinge upon. The simulated magazine case 1 also includes a third hole (indicated as 15 in FIGS. 1 & 2) in the front of said magazine case 1 to provide access to the regulating set screw 10 (shown in FIG. 19) which is mounted in the set base 5 as illustrated in FIG. 2, being adhered to the inside back wall of said magazine case 1. The simulated magazine case 1 also includes a fourth hole (indicated as 16 in FIGS. 1 & 2) beneath the previously mentioned third hole 15, and which the fourth hole 16 allows for adjusting the mounting screw (indicated as 17 in FIG. 19) for the detent reed 6. The simulated magazine case 1 also includes a fifth hole (not shown) in the back of the magazine 1 for adjusting a second set screw (not shown) in the micro switch lever (indicated as 4 in FIG. 19), the second set screw (not shown) being configured to regulate the adjusting point of another training device. The simulated magazine case 1 also includes a sixth hole (indicated as 18 in FIGS. 2 & 19) in the front of the magazine 1 to allow the swing lock (indicated as 3 in FIG. 19) to interact with a member in the pistol's magazine well (not shown) to lift and place the lever (indicated as 2 in FIG. 19) in the proper position with the pistol's trigger mechanism when the device is inserted into the pistol's magazine well.
[0045] FIGS. 3 & 4 illustrate the lever 2 sized and shaped to support the detent reed (indicated as 6 in FIG. 19), locate the compression spring (indicated as 8 in FIG. 19), mount the swing lock (indicated as 3 in FIG. 19), and mount the micro switch lever (indicated as 4 in FIG. 19), and a projection at the top to interact with the pistol's trigger mechanism at point A; all these are illustrated in FIG. 19.
[0046] FIGS. 5 & 6 illustrate the swing lock 3 which is pin mounted to the lever 2 (as shown in FIG. 19) and protrudes out of the hole (indicated as 18 in FIGS. 2 & 19) in the front of the magazine's 1 front side (as shown in FIGS. 2 & 19) to interact with a member in the pistol's magazine well (not shown) which places the lever 2 (as shown in FIG. 19) into its proper position with the pistol's trigger mechanism (not shown). In some embodiments, the swing lock 3 snaps onto a fulcrum pin that is integrated as a molded component of the lever 2.
[0047] FIGS. 7 & 8 illustrate a micro switch lever 4 which pin mounts to the lever 2 (as shown in FIG. 19), the micro switch lever 4 has a hole for accommodating a second set screw (not shown) for adjustments through the fifth hole (not shown) in the back of the magazine 1, and provides a location for mounting a micro switch 9 (shown in FIG. 19). In some embodiments, the lever 2 includes no microswitch lever 4, but instead the micro switch 9 is mounted to a PC board that is mounted in the case by screws, in such embodiments the lever 2 includes a screw to actuate the micro switch 9.
[0048] FIGS. 9 & 10 illustrate the set screw base 5 which is adhered to or at least partially captured or enveloped within the inner back wall of the magazine 1 (as shown in FIGS. 2 & 19) and accommodates the set screw 10 (shown in FIG. 19) to adjust when the detent reed 6 (shown in FIG. 19) snaps as the lever 2 (shown in FIG. 19) is actuated by the pistol's trigger mechanism (not shown) at point A (shown in FIG. 19). In some embodiments, the set screw base 5 includes a protrusion as shown in FIGS. 2, 10, and 19. In some other embodiments (not shown), the case includes a pocket or cavity instead of the protrusion shown in FIGS. 2, 10, and 19.
[0049] FIG. 11 illustrates a fulcrum pin 7 that allows the lever 2 (shown in FIG. 19) to rotate to activated the detent reed 6 (shown in FIG. 19) by the action transferred through the lever 2 (shown in FIG. 19) at point A (shown in FIG. 19), moving the detent reed 6 (shown in FIG. 19) against the set screw 10 (shown in FIG. 19), producing the simulated tactile release and the audible response of the weapon's firing pin. Another fulcrum pin (not shown) mounts the micro switch lever 4 (shown in FIG. 19) onto the lever 2 (shown in FIG. 19). In some embodiments, the fulcrum pin 7 and/or another fulcrum pin (not shown) is integrated as a part of lever 2 and/or as a molded portion of one or both case halves.
[0050] FIG. 12 illustrates a compression spring 8 that returns the lever 2 (shown in FIG. 19) to its resting position against the front of the magazine 1 (shown in FIG. 19) and resets the pistol's trigger mechanism to its resting position. The location of the compression spring 8 relative to the magazine case 1 and lever 2 is shown at FIG. 19.
[0051] FIG. 13 illustrates a detent reed 6 which is mounted to the lever 2 (shown at FIG. 19) and provides the tactile release simulating the feel of the release of the pistol's firing pin and an audible response simulating the sound of the release of the pistol's firing pin.
[0052] FIG. 14 illustrates the set screw 10 which is used in the set screw base 5 (shown at FIG. 19) and is configured to be adjustable to apply more or less pressure to the detent reed 6 (as shown in FIG. 19). A second set screw (not shown), similar to set screw 10, provides for adjustments to micro switch lever 4 (shown in FIG. 19).
[0053] FIGS. 15 & 16 illustrate the micro switch 9 which is mounted to the micro switch lever 4 (shown in FIG. 19) and presses against the inner wall of the magazine 1 (shown in FIG. 19) to activate an electronic component for other training devices. Persons of ordinary skill in the art will readily recognize that the configuration of the micro switch 9 relative to the inner wall of the magazine 1 is interchangeable, such that the micro switch 9 is mounted to the inner wall of the magazine 1 and in any event the micro switch 9 is depressed when the lever 2 is actuated by the pistol's trigger mechanism.
[0054] FIGS. 17 & 18 illustrate the micro processor 11 that is activated by the micro switch 9 (shown in FIG. 19) when the lever assembly is hinged towards the back of the magazine 1 (shown in FIG. 19) and thus provides an electrical signal received by another device for dry fire training. In some embodiments, the electrical signal includes a Bluetooth, LED, RF, and/or IR signal.
[0055] FIG. 19 illustrates a sectional view of the assembled dry fire training device showing the lever 2 in its resting position. The compression spring 8 is applying a forward force to hold the lever 2 forward. This view shows the detent reed 6 resting against the set screw 10 in its untripped or unreleased position. The set screw 10 provides adjustment to control the release of the detent reed 6 at precisely the right position in the travel of the pistol's trigger. The swing lock 3 is mounted to the lever 2 so that when the device is inserted into the pistol's magazine compartment, the swing lock 3 interacts with the pistol's magazine release bar and pushes the lever 2 towards the back of pistol far enough that the lever 2 can freely move behind the pistol's trigger mechanism. The swing lock 3 then swings out of the way so that the lever 2 assembly is free to interact with the pistol's trigger mechanism. When the pistol's trigger mechanism presses against the lever 2 at point A, the lever 2 assembly swings towards the back of the magazine 1. This movement compresses the coil spring 8, bends the detent reed 6 through its activation point against the set screw 10 and provides the tactile and the audible response, thus simulating the release of the pistol's firing pin; the micro switch 9 is compressed against the wall of the magazine 1 completing the circuit to the micro processor 11 which sends a signal to interact with a separate dry fire training device. When the pistol's trigger is released, the coil spring 8 returns the lever 2 assembly to its resting position.
[0056] The previously patented device U.S. Pat. No. 9,182,189 had a sliding member that had to be pushed up to accomplish the positioning of the lever 2 behind the trigger mechanism. Then, after the lever 2 was in its working position, the shooter needed to pull the sliding lever lifter back to its resting position. This new design accomplishes this setting action without any additional actions of the shooter. The new devise also has means of interacting electronically with other dry fire training devices.
