Abstract

A hybrid molded assembly includes a trigger comprising a trigger skeleton and a trigger molded portion that at least partially encompasses the trigger skeleton, a hammer comprising a hammer skeleton and a hammer molded portion that at least partially encompasses the hammer skeleton, and a disconnector comprising a disconnector skeleton and a disconnector molded portion that at least partially encompasses the disconnector skeleton.

First claim

That which is claimed is:

1. A hybrid trigger assembly for a firearm, the hybrid trigger assembly comprising:
a pin hole; and
a trigger rotatable about the pin hole, the trigger comprising:
a skeleton; and
a molded portion that is molded and permanently attached to the skeleton such that the molded portion at least partially encompasses the skeleton, wherein the skeleton comprises:
a central portion that is disposed adjacent to and at least partially surrounds the pin hole;
a first portion extending in a forward direction from the central portion;
a second portion extending in a rear direction from the central portion, wherein the rear direction is opposite and parallel to the forward direction; and
a third portion extending in a lower direction from the central portion, wherein the lower direction is perpendicular to the forward direction,

wherein a part of the molded portion is disposed at a part of the skeleton adjacent to the pin hole in a direction opposite to that of a finger interface portion of the skeleton.

2. The hybrid trigger assembly of claim 1 , wherein the first portion comprises a sear portion that engages a hammer.

3. The hybrid trigger assembly of claim 2 , wherein at least a portion of the sear portion protrudes through the molded portion.

4. The hybrid trigger assembly of claim 1 , wherein the second portion comprises a rear arm portion, wherein the rear arm portion supports a disconnector spring cavity.

5. The hybrid trigger assembly of claim 1 , wherein the third portion comprises the finger interface portion comprising at least one mechanical attachment for a removable modular trigger face.

6. The hybrid trigger assembly of claim 5 , wherein at least a majority of the finger interface portion protrudes through the molded portion.

7. The hybrid trigger assembly of claim 1 , wherein the molded portion encompasses at least portions of each of the first, second, and third portions.

8. The hybrid trigger assembly of claim 1 , wherein the second portion comprises a selector portion, wherein the selector portion engages a safety selector.

9. The hybrid trigger assembly of claim 8 , wherein at least a portion of the selector portion protrudes to an outer surface of the molded portion.

10. The hybrid trigger assembly of claim 1 , wherein the molded portion comprises a polymer material.

11. The hybrid trigger assembly of claim 1 , wherein the skeleton comprises a steel material.

12. The hybrid trigger assembly of claim 1 , wherein the skeleton comprises a hole that is concentric with the pin hole.

13. The hybrid trigger assembly of claim 1 , wherein the molded portion comprises at least one hole.

14. The hybrid trigger assembly of claim 13 , wherein the at least one hole is arranged such that a fastener can be inserted from above in the lower direction such that the fastener protrudes out of the bottom of the molded portion.

15. The hybrid trigger assembly of claim 13 , wherein the at least one hole is offset toward a left hand side of the trigger when viewed from above.

16. The hybrid trigger assembly of claim 1 , wherein the skeleton is a unitary component.

17. A hybrid trigger assembly for a firearm, the hybrid trigger assembly comprising:
a skeleton;
a molded portion that is molded onto the skeleton and at least partially encompasses the skeleton; and
a pin hole, wherein the skeleton comprises:
a plurality of exposed portions that protrude to an outer surface of the molded portion;
a central portion that is disposed adjacent to and at least partially surrounds the pin hole; and
three portions that extend away from the central portion,

wherein a part of the molded portion is disposed at the rearmost portion of the skeleton such that the rearmost portion is distal from a finger interface portion of the skeleton.

18. The hybrid trigger assembly of claim 17 , wherein the three portions comprise:
a first portion extending in a forward direction from the central portion;
a second portion extending in a rear direction from the central portion, wherein the rear direction is opposite and parallel to the forward direction; and
a third portion extending in a lower direction from the central portion, wherein the lower direction is perpendicular to the forward direction.

19. The hybrid trigger assembly of claim 18 , wherein the plurality of exposed portions comprises:
a sear portion that engages a hammer, wherein the sear portion is disposed on the first portion; and
the finger interface portion being disposed on the third portion.

20. The hybrid trigger assembly of claim 17 , wherein the skeleton comprises a hole that is concentric with the pin hole.

21. The hybrid trigger assembly of claim 17 , wherein the molded portion comprises at least one hole for a fastener.

22. The hybrid trigger assembly of claim 17 , wherein the skeleton is a unitary component.

23. A hybrid trigger assembly for a firearm, the hybrid trigger assembly comprising:
a pin hole; and
a trigger rotatable about the pin hole, the trigger comprising:
a skeleton; and
a molded portion that is molded onto the skeleton and at least partially encompasses the skeleton, wherein the skeleton comprises:
a central portion that is disposed adjacent to and at least partially surrounds the pin hole;
a first portion extending in a forward direction from the central portion, wherein the first portion comprises a sear portion that engages a hammer;
a second portion extending in a rear direction from the central portion, wherein the rear direction is opposite and parallel to the forward direction; and
a third portion extending in a lower direction from the central portion, wherein the lower direction is perpendicular to the forward direction,

wherein at least a portion of the sear portion protrudes through the molded portion.

24. A hybrid trigger assembly for a firearm, the hybrid trigger assembly comprising:
a pin hole; and
a trigger rotatable about the pin hole, the trigger comprising:
a skeleton; and
a molded portion that is molded onto the skeleton and at least partially encompasses the skeleton, wherein the skeleton comprises:
a central portion that is disposed adjacent to and at least partially surrounds the pin hole;
a first portion extending in a forward direction from the central portion;
a second portion extending in a rear direction from the central portion, wherein the rear direction is opposite and parallel to the forward direction; and
a third portion extending in a lower direction from the central portion, the third portion comprising a finger interface portion comprising at least one mechanical attachment on a forward side of the finger interface portion for a removable modular trigger face, wherein the lower direction is perpendicular to the forward direction.

25. A hybrid trigger assembly for a firearm, the hybrid trigger assembly comprising:
a pin hole; and
a trigger rotatable about the pin hole, the trigger comprising:
a skeleton; and
a molded portion that is molded onto the skeleton and at least partially encompasses the skeleton, wherein the skeleton comprises:
a central portion that is disposed adjacent to and at least partially surrounds the pin hole;
a first portion extending in a forward direction from the central portion;
a second portion extending in a rear direction from the central portion, wherein the rear direction is opposite and parallel to the forward directio
