Abstract

An electro-mechanical firearm trigger mechanism for controlling the rate of fire for a firearm in automatic firing mode. The controlling being achieved through the use of a solenoid directed by a computer processor. The computer processor being connected to multiple sensors to instruct the solenoid on a rate of fire or to disengage automatic fire if needed.

Claims (29)

1. An electro-mechanical trigger mechanism for controlling automatic firing of a firearm, the electro mechanical trigger mechanism comprising:

a firing mode selector for placing the firearm in an automatic firing mode and a semi-automatic firing mode;

a solenoid operatively connected to a sear disconnect of the firearm;

a processor operatively coupled to the solenoid, wherein the processor actuates the solenoid when a trigger of the electro-mechanical trigger mechanism is actuated and the firearm is in the automatic firing mode; and

wherein the solenoid is not actuated when the trigger of the electro-mechanical trigger mechanism is actuated and the firearm is in the semi-automatic firing mode.

2. The electro-mechanical trigger mechanism of claim 1 wherein the solenoid further comprises a solenoid plunger extending between the solenoid and the sear disconnect.

3. The electro-mechanical trigger mechanism of claim 2 further comprising: a power source connected to the solenoid.

4. The electro-mechanical trigger mechanism of claim 1 further comprising: a firing mode selector sensor for monitoring a firing mode selected by the firing mode selector; wherein the firing mode selector sensor is in communication with the processor to indicate when the firearm is in an automatic firing mode.

5. The electro-mechanical trigger mechanism of claim 4 further comprising: a timer for monitoring the rate of fire of the firearm, the timer in communication with the processor.

6. The electro-mechanical trigger mechanism of claim 1 further comprising: a barrel temperature sensor; wherein the barrel temperature sensor is in communication with the processor to transmit a barrel temperature such that if the barrel temperature is greater than a predetermined value, the processor increases the cycle time of the solenoid to reduce a rate of fire.

7. The electro-mechanical trigger mechanism of claim 1 , further comprising a sensor configured to detect the position of the trigger, wherein the sensor is operatively coupled to the processor.

8. The electro-mechanical trigger mechanism of claim 1 , further comprising a sensor configured to detect whether the firearm is in either the automatic or the semi-automatic firing mode, wherein the sensor is operatively coupled to the processor.

9. The electro-mechanical trigger mechanism of claim 1 , further comprising a temperature sensor configured to detect a temperature of a barrel of the firearm, wherein the temperature sensor is operatively coupled to the processor.

10. The electro-mechanical trigger mechanism of claim 1 , further comprising a trigger sensor configured to detect the position of the trigger, wherein the trigger sensor is operatively coupled to the processor;

a firing mode sensor configured to detect whether the firearm is in either the automatic or the semi-automatic firing mode, wherein the firing mode sensor is operatively coupled to the processor; and

a temperature sensor configured to detect a temperature of a barrel of the firearm, wherein the temperature sensor is operatively coupled to the processor.

11. The electro-mechanical trigger mechanism of claim 10 , further comprising a timer, wherein the timer is operatively coupled to the processor.

12. The electro-mechanical trigger mechanism of claim 1 , further comprising a timer, wherein the timer is operatively coupled to the processor.

13. The electro-mechanical trigger mechanism of claim 1 , wherein the processor is configured to provide a predetermined number of current pules to the solenoid when the trigger is depressed and the firearm is in an automatic firing mode.

14. An electro-mechanical trigger mechanism for a firearm, the electro mechanical trigger mechanism being capable of operating in an automatic firing mode and a semi-automatic firing mode; a firing mode selector for placing the firearm in the automatic firing mode and the semi-automatic firing mode; a solenoid for use only in the automatic firing mode, the solenoid being operatively connected to a sear disconnect of the firearm; a processor operatively coupled to the solenoid, wherein the processor actuates the solenoid when a trigger of the electro-mechanical trigger mechanism is actuated and the firearm is in the automatic firing mode; and wherein the solenoid is not actuated when the trigger of the electro-mechanical trigger mechanism is actuated and the firearm is in the semi-automatic firing mode.

15. The electro-mechanical trigger mechanism of claim 14 , further comprising a sensor configured to detect the position of the trigger, wherein the sensor is operatively coupled to the processor.

16. The electro-mechanical trigger mechanism of claim 14 , further comprising a sensor configured to detect whether the firearm is in either the automatic or the semi-automatic firing mode, wherein the sensor is operatively coupled to the processor.

17. The electro-mechanical trigger mechanism of claim 14 , further comprising a temperature sensor configured to detect a temperature of a barrel of the firearm, wherein the temperature sensor is operatively coupled to the processor.

18. The electro-mechanical trigger mechanism of claim 14 , further comprising a trigger sensor configured to detect the position of the trigger, wherein the trigger sensor is operatively coupled to the processor;

a firing mode sensor configured to detect whether the firearm is in either the automatic or the semi-automatic firing mode, wherein the firing mode sensor is operatively coupled to the processor; and

a temperature sensor configured to detect a temperature of a barrel of the firearm, wherein the temperature sensor is operatively coupled to the processor.

19. The electro-mechanical trigger mechanism of claim 18 , further comprising a timer, wherein the timer is operatively coupled to the processor.

20. The electro-mechanical trigger mechanism of claim 14 , further comprising a timer, wherein the timer is operatively coupled to the processor.

21. The electro-mechanical trigger mechanism of claim 14 , wherein the processor is configured to provide a predetermined number of current pules to the solenoid when the trigger is depressed and the firearm is in an automatic firing mode.
