Abstract

The present disclosure provides a trigger assembly and related method for a firearm (e.g., an AR, SR-25, or M4 style rifle, or another type of firearm). The trigger assembly minimizes inadvertent discharge of the firearm by blocking the trigger from rearward pivoting until pressure is applied to the center portion of the trigger. The system and method employ a configuration wherein a camming surface is engaged with a machined portion of the lower receiver once the trigger assembly is connected to the lower receiver via a pivot that extends through the trigger assembly and at least a portion of the lower receiver.

First claim

What is claimed is:

1. A trigger assembly, comprising:
a trigger body, the trigger body including a downwardly extending finger engaging trigger member portion;
a paddle release that extends downwardly through a portion of the finger engaging trigger member portion, the paddle release including:
a pivot located at an upper portion of the finger engaging trigger member;
a finger engaging leading edge portion;
a rotary camming surface located above and rearward of the pivot,

wherein the rotary camming surface is configured to engage a surface when the paddle release is not in a depressed orientation, and
wherein the trigger assembly is configured such that, if the downwardly extending finger engaging trigger member portion is depressed until a pivoting motion of the downwardly extending finger engaging trigger member portion is blocked by the rotary camming surface, the paddle release may then be depressed from an undepressed orientation without changing the orientation of the blocked downwardly extending finger engaging trigger member portion.

2. The trigger assembly of claim 1 , further comprising:
a plunger engaging surface adjacent the rotary camming surface located above the pivot, and a biased plunger positioned within the trigger body and configured to engage the plunger engaging surface to bias the paddle release in a forward direction.

3. The trigger assembly of claim 2 , wherein the plunger engaging surface is curved and located above the pivot adjacent to the rotary camming surface.

4. The trigger assembly of claim 1 , wherein the paddle release includes an undepressed orientation, wherein in the undepressed orientation the finger engaging leading edge portion is forward of the leading edge of the downwardly extending finger engaging trigger member portion of the trigger body.

5. The trigger assembly of claim 1 , wherein the paddle release extends through the upper portion and middle portion of the downwardly extending finger engaging trigger member portion.

6. The trigger assembly of claim 1 , the finger engaging leading edge portion of the paddle release extends forward of the leading edge of the downwardly extending finger engaging trigger member portion of the trigger body in the middle portion of the downwardly extending finger engaging trigger member portion.

7. The trigger assembly of claim 1 , the finger engaging leading edge portion of the paddle release extends forward of the leading edge of the downwardly extending finger engaging trigger member portion of the trigger body only in the middle portion of the downwardly extending finger engaging trigger member portion.

8. The trigger assembly of claim 1 , wherein the paddle release includes an upper edge located immediately above the finger engaging leading edge portion, wherein the upper edge and the downwardly extending finger engaging trigger member portion define an angle of 70-110 degrees.

9. The trigger assembly of claim 1 , wherein the paddle release includes a lower edge located immediately below the finger engaging leading edge portion, wherein the lower edge and the downwardly extending finger engaging trigger member portion define an angle of 70-110 degrees.

10. The trigger assembly of claim 1 , wherein the pivot range of the trigger body is limited to less than 5 degrees until the paddle release is in a depressed orientation.

11. The trigger assembly of claim 1 , wherein the rotary camming surface of the paddle release is about 1 mm to about 4 mm long.

12. The trigger assembly of claim 1 , further comprising a biased plunger positioned within the trigger body and configured to engage the plunger engaging surface to bias the paddle release in a forward direction.

13. The trigger assembly of claim 12 , wherein the biased plunger is configured to be in constant sliding contact with the plunger engaging surface.

14. The trigger assembly of claim 1 , wherein the paddle release is configured to resist movement from above and force from below the pivot due to force applied in the trigger pull direction.

15. The trigger assembly of claim 1 , wherein the travel of the finger engaging leading edge portion of the paddle release from an undepressed position to a depressed position is greater than 3 mm.

16. The trigger assembly of claim 1 , wherein the paddle release is configured to limit the pivot range of the trigger body by a consistent amount until the paddle release is in a fully depressed orientation and allow the trigger body to pivot freely once the paddle release is in the fully depressed orientation.

17. A firearm comprising the trigger assembly of claim 1 .

18. The trigger assembly of claim 1 , wherein the rotary camming surface has a faceted profile comprising connected flat straight surfaces.
