Abstract

A sliding trigger enclosure system for a long gun includes a frame that is removably secured to the receiver of a firearm by factory-supplied hardware, and a hollow shoulder stock having a pair of side surfaces that extend outward from the front end. The shoulder stock is slidingly engaged over the frame and transitions between a FIRE position where the trigger assembly of the long gun is accessible, and a SAFE position where the pair of side surfaces are locked in a parallel orientation to the trigger assembly to prevent access to the same. A locking mechanism is disposed along the frame and secures the shoulder stock in the SAFE position. The locking mechanism including a pair of spring-loaded locking pins that are engaged by an actuator, and a user authentication device.

Claims

1. A sliding trigger enclosure system for a long gun, said system comprising:

a frame having a plurality of sides, a back end, and a front end that is configured to be secured to a receiver of a long gun;

a hollow shoulder stock that is slidingly engaged to the frame, said shoulder stock having a back end, a front end, and a pair of side surfaces that extend outward from the front end; and

a locking mechanism that is disposed along the frame,

wherein the shoulder stock is configured to transition between a FIRE position where a trigger assembly of the long gun external to the frame is accessible, and a SAFE position where the pair of side surfaces are locked in a parallel orientation to the trigger assembly of the long gun to prevent access to the trigger assembly.

2. The system of claim 1, further comprising:

a mounting aperture that is positioned along the front end of the frame at a location that is complementary to a location of a threaded aperture located on the receiver of the long gun, and

said mounting aperture including a shape that is suitable for receiving a factory bolt for securing the frame to the receiver.

3. The system of claim 1, wherein the locking mechanism comprises:

at least one locking pin that is configured to transition between an extended position and a retracted position; and

an actuator that functions to transition each of the at least one locking pin between the extended position and the retracted position,

wherein in the extended position each of the at least one locking pins are configured to engage the back end of the shoulder stock to lock the shoulder stock in the SAFE position, and

in the retracted position the shoulder stock is in the FIRE position.

4. The system of claim 3, wherein each of the at least one locking pins comprise a spring loaded locking pin that defaults to the extended position.

5. The system of claim 4, wherein the actuator is configured to receive a pressing force that transitions each of the at least one locking pins from the extended position to the retracted position.

6. The system of claim 3, further comprising:

a user interface that is configured to receive a user instruction to allow operation of the actuator.

7. The system of claim 6, wherein the user interface includes a mechanical combination lock.

8. The system of claim 6, wherein the user interface includes a biometric sensor.

9. The system of claim 1, wherein the stock is slidingly engaged to the frame by a pair of channels that are disposed longitudinally along an outside surface of the frame, and a pair of complementary grooves that are disposed longitudinally along an inside facing surface of the frame.

10. The system of claim 1, further comprising:

a recoil pad that is removably secured to the back end of the frame.

11. The system of claim 10 wherein the recoil pad is secured to the frame via one or more security bolts.

12. The system of claim 1, further comprising:

a pair of retaining tabs that are located along the back end of the frame, said retaining tabs being configured to engage the back end of the sliding stock in the FIRE position.

13. A firearm having a sliding trigger enclosure system, said firearm comprising:

a receiver having a back end and a bottom end;

a trigger assembly that is positioned along the bottom end of the receiver;

a frame having a plurality of sides, a back end, and a front end that is secured to the back end of the receiver;

a hollow shoulder stock that is slidingly engaged to the frame, said shoulder stock having a back end, a front end, and a pair of side surfaces that extend outward from the front end; and

a locking mechanism that is disposed along the frame,

wherein the shoulder stock is configured to transition between a FIRE position where the trigger assembly of the firearm is accessible, and a SAFE position where the pair of side surfaces are locked in a parallel orientation to the trigger assembly of the firearm to prevent access to the trigger assembly.

14. The system of claim 13, wherein the locking mechanism comprises:

at least one locking pin that is configured to transition between an extended position and a retracted position; and

an actuator that functions to transition each of the at least one locking pin between the extended position and the retracted position,

wherein in the extended position each of the at least one locking pins are configured to engage the back end of the shoulder stock to lock the shoulder stock in the SAFE position, and

in the retracted position the shoulder stock is in the FIRE position.

15. The system of claim 14, wherein each of the at least one locking pins comprise a spring loaded locking pin that defaults to the extended position.

16. The system of claim 14, wherein the actuator is configured to receive a pressing force that transitions each of the at least one locking pins from the extended position to the retracted position.

17. The system of claim 14, further comprising:

a user interface that is configured to receive a user instruction to allow operation of the actuator, said user interface including at least one of a mechanical combination lock or a biometric sensor.

18. The system of claim 13, further comprising:

a recoil pad that is removably secured to the back end of the frame.

19. The system of claim 18 wherein the recoil pad is secured to the frame via one or more security bolts.

20. The system of claim 13, further comprising:

a pair of retaining tabs that are located along the back end of the frame, said retaining tabs being configured to engage the back end of the sliding stock in the FIRE position.
