TECHNICAL FIELD
This invention relates to firearms, and more particularly to a dry fire training device.
BACKGROUND OF THE INVENTION
Live firing is the best way to practice drawing and firing a weapon. 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.
Dry fire practice is a good substitute for live fire practice. Dry firing is another process of building muscle memory whereby a firearm, especially a pistol, 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.
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.
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 novice shooter accustomed to the trigger feel before having to deal with the recoil and the report of live firing.
A major negative factor occurs with most methods of dry firing because when a semi-automatic pistol is live fired, it resets its firing pin and is the pistol ready to be fired again until the magazine is empty. The shooter's hands remain in the firing position, and just the trigger finger and the trigger are employed. With normal dry fire practice, after the first activation of the trigger 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. The shooter can then let the trigger return to its 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.
Another negative for standard dry fire practice is there is concern as to wear and tear on the constant releasing of a weapon's firing pin without it having the cushioning effect of the firing pin striking a round of ammunition.
Some patent 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.
Here are a few examples of pistol training patents:

These are some devices or systems that aid in dry fire practice, but only one of the patented devices (U.S. Pat. No. 9,182,189) or systems address the “hands-free” trigger reset problem or the firing pin use problem.
Negative qualities of these devices or systems are that they are either user intensive and/or expensive to purchase, but most significantly they do not allow a shooter to use a fully functioning pistol that he may already own. There is also a learning curve or training necessary to use these systems, but most of all, none of the patented devices or systems except (U.S. Pat. No. 9,182,189) address the “hands-free” trigger reset problem and the possible firing pin damage problem of normal dry fire practice.
The device with U.S. Pat. No. 9,182,189 (my previous patent) solves all of the stated problems, but there are improvements that need to be made. The means for insertion into the magazine's well has been simplified, internal parts have been improved, and alterations have been provided so that the device can interact with electronic training systems through a micro switch and electronic components.
There is no device that provides proper dryfire training as already described that also has components that will allow it to interact with electronic training devices like lasers, simulators, and virtual reality.
There is therefore a need for a dry fire training device that uses a fully functioning pistol, allows for precise muscle memory training, is simple to operate, prevents the firing pin of the fully functioning pistol from being damaged, provides for safe on-site home training, inserts easily into the magazine well, and has capabilities to interact with electronic training systems. This new device improves upon existing device U.S. Pat. No. 9,182,189 (my previous patent).
BRIEF SUMMARY OF THE INVENTION
The invention that is to be described accomplishes the most important aspects of dry fire training: no live ammunition is used providing safety and no on-going expense, convenience of practicing in the home environment where the protective, fully functioning pistol would most likely be used for defensive purposes, no involved disassembling and reassembling of any of the fully functional pistol's components, the realistic feel of the trigger during the firing process and the trigger reset, precise muscle memory training using only the trigger finger motion, and does not negatively affect the fully functional pistol's firing pin. This invention also helps the novice shooter train with his pistol before he has to deal with the recoil and the report of firing live ammunition. This invention is simple to use, provides realistic feel of the trigger operation, produces a sound that simulates the release of the pistol's firing pin, and does not require any alterations to the fully functional pistol such as disassembling and reassembling of any parts of the pistol. There is therefore a need for a dry fire training device that uses a fully functioning pistol, allows for precise muscle memory training, is simple to operate, prevents the firing pin of the fully functioning pistol from being damaged, provides for safe on-site home training, inserts easily into the magazine well, and has capabilities to interact with electronic training systems. This new device improves upon existing device U.S. Pat. No. 9,182,189 (my previous patent). This improved device addresses these situations through the pistol's magazine compartment. This invention simply slides into the magazine compartment in the pistol's handle, and practice can begin. It requires no alterations to the pistol before or after practice. This new device functions completely independent of the pistol's firing pin.
An additional point of safety is that the base plate, which is always visible to the shooter and trainer, is a bright color, such as orange or florescent green or pink, to identify the device as being safe and quickly and easily visibly distinguishable from a magazine that could contain live ammunition. There is no way that this device can mechanically accommodate any live ammunition.

DETAILED DESCRIPTION OF THE INVENTION
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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
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.
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.
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.
