DETAILED DESCRIPTION OF THE INVENTION
(20) FIGS. 1 & 2 illustrate the simulated magazine case 1 that has six holes: a pair of holes in each side to receive the fulcrum pin 7 for the lever 2 to hinge upon; a third hole in the front of said magazine 1 to provide access to the regulating set screw 10 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; a forth hole beneath the previously mentioned hole which allows for adjusting the mounting screw for the detent reed 6; a fifth hole in the back of the magazine 1 for adjusting a second set screw 10 in the micro switch lever 4 to regulate the adjusting point of another training device; a sixth hole in the front of the magazine 1 to allow the swing lock 3 to interact with a member in the pistol's magazine well to lift and place the lever 2 in the proper position with the pistol's trigger mechanism when the device is inserted into the pistol's magazine well.
(21) FIGS. 3 & 4 illustrate the lever 2 with various shapes that allow it to support the detente reed 6, locate the coil spring 7, mount the swing lock 3, and mount the micro switch lever 4, and a projection at the top to interact with the pistol's trigger mechanism at point A; all these are illustrated in FIG. 19.
(22) FIGS. 5 & 6 illustrate the swing lock 3 which is pin mounted to the lever 2 and protrudes out of the hole in the front of the magazine's 1 front side to interact with a member in the pistol's magazine well which places the lever 2 into its proper position with the pistol's trigger mechanism.
(23) FIGS. 7 & 8 illustrate a lever 4 which pin mounts to the lever 2, has a hole for accommodating the set screw 10 for adjustments, and provides a location for mounting a micro switch 9.
(24) FIGS. 9 & 10 illustrate the set screw base 5 which is adhered to the inner front wall of the magazine 1 and accommodates the set screw 10 to adjust when the detente reed 6 snaps as the lever 2 is actuated by the pistol's trigger mechanism at point A.
(25) FIG. 11 illustrates a fulcrum pin 6 that allows the lever 5 to rotate to activated the detent reed 6 by the action transferred through the lever 5 at point A, moving the detent reed 6 against the set screw 10, producing the simulated tactile release and the audible response of the weapon's firing pin. Another fulcrum pin 7 mounts the micro switch lever 4 onto the lever 2.
(26) FIG. 12 illustrates a compression spring 8 that returns the lever 2 to its resting position against the front of the magazine 1 and resets the pistol's trigger mechanism to its resting position.
(27) FIG. 13 illustrates a detent reed 6 which is mounted to the lever 2 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.
(28) FIG. 14 illustrates the set screw 10 which is used in the set screw base 5 and the micro switch lever 4 and provides for adjustments of both as illustrated in FIG. 19.
(29) FIGS. 15 & 16 illustrate the micro switch 9 which is mounted to its lever 4 and presses against the inner wall of the magazine 1 to activate an electronic component for other training devices.
(30) FIGS. 17 & 18 illustrate the micro processor 11 that is activated by the micro switch 9 when the lever assembly is hinged towards the back of the magazine 1 and thus provides an electrical signal received by another device for dry fire training.
(31) 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 pressed 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 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.
(32) 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.
