Dry fire training device
A multi-function dry fire training device to be inserted into the chamber of a firearm, which comprises an illuminator for emitting, upon receiving a command from a controller, a beam of visible or invisible illumination from the barrel of the firearm, the beam being parallel to its central axis; a controller for controlling the functionality of the device including illumination of the illuminator, in response to activation of the firearm trigger; an actuator, being electrically connected to the controller, for activating the controller whenever being struck by the firearm striker and a power source for providing DC power to the controller and illuminator.
1. A training device for insertion into a firearm chamber comprising:
a first casing which comprises a front end which comprises a first opening, a rear end which comprises a second opening, and a first attachment structure;
an input device abutting the rear end which comprises a first component disposed in the second opening for receiving a mechanical impulse such that the first component is movable from a ready position to an actuated position which is spaced from the ready position;
a signaling mechanism proximate to the first component such that the signaling mechanism transforms kinetic energy received from a striker of a firearm into data signals an indication selected from the group consisting of a momentary connection, specific timed connection, disconnection, specific timed disconnection, an increase in conductivity, decrease in conductivity, electrical surge, reverse polarity, and a data signal;
a control circuit board adjacent the input device; and
a securing element which comprises a second attachment structure such that the second attachment structure mates with the first attachment structure to secure the input device and the circuit board in the first casing.
2. The training device of claim 1 , wherein the training device further comprises:
a second terminal; and
the control circuit board comprises an input lead connected to the signaling mechanism for receiving data signals the indication, an output lead for transmitting control signals in response to the data signals indication, a first conductor for connecting to a first terminal, and a second conductor connected to the second terminal.
3. The training device of claim 2 , wherein the second terminal is configured and dimensioned for connecting to a second side of a power source.
4. The training device of claim 3 , wherein the second terminal is a first spring.
5. The training device of claim 1 , wherein the first casing further comprises:
an intermediate portion spaced from the front end, the intermediate portion comprising a first outer dimension;
a rear portion abutting the rear end, the rear portion comprising a second outer dimension which is less than the first outer dimension; and
a shoulder portion interconnecting the intermediate portion and the rear portion.
6. The training device of claim 1 , further comprising a damping structure adjacent the first component such that the damping structure biases the first component in the ready position and dissipates kinetic energy transmitted by the first component when the first component moves from the ready position to the actuated position.
7. The training device of claim 1 , wherein the signaling mechanism comprises a conductive member.
8. The training device of claim 1 , further comprising:
a second casing having a second longitudinal axis which comprises
a front end defining a front opening, and
a rear end defining a rear opening;
a light source positioned in the second casing; and
a lens adjacent the front opening.
9. The training device of claim 8 , further comprising a first terminal and a second terminal wherein the first terminal is configured and dimensioned for connecting to a first side of a power source.
10. The training device of claim 9 , wherein the first terminal is a second spring.
11. The training device of claim 9 , further comprising a power supply.
12. The training device of claim 11 , wherein the power supply is positioned between the first terminal and the second terminal.
13. The training device of claim 11 , wherein the power supply provides power to the light source.
14. The training device of claim 8 , wherein the lens is configured and dimensioned to focus emissions of light originating from the light source onto a focused area.
15. The training device of claim 8 , further comprising a collimator, the collimator comprising a third tubular member which comprises an upper a first surface, a lower second surface, and an inner surface extending between the upper surface and the lower surface, the inner surface having a first fastening thread.
16. The training device of claim 15 , wherein the collimator further comprises a hollow insert connected to the third tubular member, the hollow insert comprising an exterior surface having a second fastening thread which mates with the first fastening thread, the lens being fixed between the front opening and the lower surface, and the light source being connected to the hollow insert and spaced from the lens by a first distance for focusing emissions of light from the light source onto a focused area.
17. The training device of claim 8 , wherein the second casing comprises a third attachment structure such that the third attachment structure mates with the first attachment structure to secure the second casing to the first casing.
18. The training device of claim 8 , wherein the light source comprises a light emitting diode which emits light having a dominant wavelength of between approximately 635 nm and approximately 850 nm.
19. The training device of claim 8 , wherein the light source comprises a laser diode.
20. The training device of claim 8 , wherein the light source comprises a light emitting diode which emits light having a dominant wavelength of approximately 780 nm.
