Hybrid molded firearm assemblies
View Patent ↗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.
1. A hybrid hammer assembly for a firearm, the hybrid hammer assembly comprising:
a pin hole;
a hammer rotatable about the pin hole, the hammer comprising:
a metallic hammer skeleton comprising a firing pin interface surface; and
a hammer molded portion that at least partially encompasses the metallic hammer skeleton, wherein the metallic hammer skeleton comprises:
a first portion disposed adjacent to and at least partially surrounding the pin hole; and
a second portion extending from the pin hole towards and beyond the firing pin interface surface.
2. The hybrid hammer assembly of claim 1 , wherein at least a portion of the firing pin interface surface protrudes through the hammer molded portion.
3. The hybrid hammer assembly of claim 1 , wherein the metallic hammer skeleton comprises a sear protrusion that engages a trigger, wherein the sear protrusion is disposed adjacent to the pin hole.
4. The hybrid hammer assembly of claim 3 , wherein at least a portion of the sear protrusion protrudes through the hammer molded portion.
5. The hybrid hammer assembly of claim 1 , wherein the metallic hammer skeleton comprises a disconnector interface tooth that engages a disconnector, wherein the disconnector interface tooth is disposed on a rear side of the hammer that is opposite of the firing pin interface surface.
6. The hybrid hammer assembly of claim 5 , wherein at least a portion of the disconnector interface tooth protrudes through the hammer molded portion.
7. The hybrid hammer assembly of claim 1 , wherein the metallic hammer skeleton comprises a plurality of assembly holes, wherein a portion of the hammer molded portion fills at least some of the plurality of assembly holes to aid in mechanical attachment between the metallic hammer skeleton and the hammer molded portion.
8. The hybrid hammer assembly of claim 1 , wherein the hammer molded portion comprises a polymer material.
9. The hybrid hammer assembly of claim 1 , wherein the metallic hammer skeleton comprises a steel material.
10. The hybrid hammer assembly of claim 1 , wherein the firing pin interface surface is one of at least two parts of the metallic hammer skeleton that protrude to be at least flush with an outer surface of the hammer molded portion.
11. The hybrid hammer assembly of claim 1 , wherein the metallic hammer skeleton comprises a hole that is concentric with the pin hole.
12. A hybrid hammer assembly for a firearm, the hybrid hammer assembly comprising:
a pin hole;
a hammer rotatable about the pin hole, the hammer comprising:
a metallic hammer skeleton comprising a firing pin interface surface; and
a hammer molded portion that at least partially encompasses the metallic hammer skeleton; and
a plurality of movable portions adjacent to the pin hole, wherein each of the movable portions are movable in a radial direction relative to the pin hole.
13. The hybrid hammer assembly of claim 12 , wherein the plurality of movable portions are separated from one another by slots.
14. The hybrid hammer assembly of claim 12 , wherein each of the movable portions comprise a protrusion that extends in the radial direction toward a center of the pin hole.
15. The hybrid hammer assembly of claim 14 , wherein the protrusions engage at least one notch in a pivot pin that is inserted into the pin hole.
16. The hybrid hammer assembly of claim 12 , wherein the plurality of movable portions are integral components of the hammer molded portion.
17. The hybrid hammer assembly of claim 12 , wherein the hammer molded portion comprises an injection-molded material.
18. The hybrid hammer assembly of claim 12 , wherein the hammer molded portion comprises a polymer material.
19. The hybrid hammer assembly of claim 12 , wherein the metallic hammer skeleton comprises a hole that is concentric with the pin hole.
20. The hybrid hammer assembly of claim 12 , wherein the firing pin interface surface is one of at least two parts of the metallic hammer skeleton that protrude to be at least flush with an outer surface of the hammer molded portion.
