Abstract

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.

Claims (30)

1. A dry fire training device for emitting light through a barrel of a firearm, comprising;

an electronic circuit including:

a power supply;

an illuminator situated on a first side of the power supply; and

a control circuit situated on a second side of the power supply,

wherein the control circuit is connected to the illuminator by two electric conductors, a first conductor connected to a first pole of the illuminator and the power supply, and a second conductor connected to a second pole of the illuminator.

2. The dry fire training device of claim 1 , wherein a third electric conductor is connected between the power supply and the control circuit.

3. The dry fire training device of claim 1 , wherein the electronic circuit further includes an indicator.

4. The dry fire training device of claim 1 , wherein the control circuit includes a capacitor.

5. The dry fire training device of claim 1 , wherein the control circuit includes an electrically rechargeable component.

6. The dry fire training device of claim 1 , wherein the first casing includes an actuator for generating an electric indication in response to a mechanical activation of the firearm.

7. A dry fire training device for emitting light through a barrel of a firearm, comprising;

an electronic circuit including:

a first section containing an illuminator;

a second section containing a power supply; and

a third section containing a control circuit and an electronic indicator,

wherein the control circuit is connected to the illuminator by two electric conductors, a first conductor connected to a first pole of the illuminator and the power supply, and a second conductor connected to a second pole of the illuminator.

8. The dry fire training device of claim 7 , wherein the third section further contains an indicator.

9. The dry fire training device of claim 7 , wherein the electronic circuit contains an electric conductor.

10. The dry fire training device of claim 9 , wherein a third electric conductor is connected between the power supply and the control circuit.

11. A dry fire training device for emitting light through a barrel of a firearm, comprising;

a hollow body including:

a first casing; and

a second casing connected to and in electrical contact with the first casing; and

an illuminator disposed within and in electrical contact with the second casing,

wherein the hollow body completes the electrical circuit for activation of the illuminator.

12. The dry fire training device of claim 11 , wherein the first casing further comprises a front end which comprises a first opening, and a rear end which comprises a second opening.

13. The dry fire training device of claim 12 , further comprising an input device abutting the rear end, the input device comprising of a first component for receiving a mechanical impulse such that the first component is moveable from a ready position to an actuated position.

14. The dry fire training device of claim 11 , further comprising a signaling mechanism proximate to the first component such that the signaling mechanism transforms kinetic energy received from a striker of a firearm into an electrical signal.

15. The dry fire training device of claim 14 , wherein the electrical signal is an indication that includes one of a momentary connection, specific timed connection, disconnection, specific timed disconnection, increase in conductivity, decrease in conductivity, electrical surge, reverse polarity, or data signal.
