Abstract

A firearm pin assembly is provided. A firearm pin may have a substantially cylindrical member with a lever on one end and a track running along its side. The track may run helically for a portion of its path. The track may also have at least one dimple disposed within its path. The firearm pin assembly may have an aperture for installing a detent and detent spring. The firearm pin assembly may be used in any firearm, including but not limited to a takedown pin and pivot pin assembly in an AR-15 style rifle.

Claims

1. A firearm pin device comprising:

a substantially cylindrical member having a first end and a second end, a pin head, a track and at least one dimple;

wherein the pin head is attached to the first end of the substantially cylindrical member;

the track begins proximate the first end of the substantially cylindrical member, runs substantially helically along a perimeter of the substantially cylindrical member for a distance from the first end, and then runs coaxially with the substantially cylindrical member along its perimeter to a point proximate the second end of the substantially cylindrical member; and

the at least one dimple is disposed within the track.

2. The device of claim 1, wherein the helical portion of the track travels between approximately 65 degrees and approximately 115 degrees about the circumference of the substantially cylindrical member.

3. The device of claim 1, wherein the helical portion of the track travels between approximately 155 degrees and approximately 205 degrees about the circumference of the substantially cylindrical member.

4. The device of claim 1, wherein the at least one dimple is disposed on the bottom surface of said track.

5. The device of claim 1, wherein a first dimple is disposed within the track proximate the first end of the substantially cylindrical member and a second dimple is disposed within the track proximate the second end of the substantially cylindrical member.

6. A firearm pin device comprising:

a substantially cylindrical member having a first end and a second end, a pin head, a track, at least one dimple, and at least one aperture;

wherein the pin head is attached to the first end of the substantially cylindrical member;

the track begins proximate the first end of the substantially cylindrical member and runs to a point proximate the second end of the substantially cylindrical member;

the at least one dimple is disposed within the track; and

the at least one aperture is configured to allow a detent and detent spring to pass through the substantially cylindrical member, perpendicular to a centerline longitudinal axis, without intersecting the track.

7. The firearm pin device of claim 6, wherein the at least one aperture is disposed proximate the second end of the substantially cylindrical member.

8. The firearm pin device of claim 6, further comprising a detent disengagement aperture configured to pass, perpendicularly to the centerline longitudinal axis, through the substantially cylindrical member such that it passes through the track;

wherein the detent disengagement aperture is configured to allow an object to pass through the substantially cylindrical member, apply pressure to a detent, compress a detent spring, and allow the firearm pin device to rotate free from restriction.

9. A firearm pin device comprising:

a substantially cylindrical member having a first end and a second end, a pin head, a track and at least one dimple;

wherein the pin head is attached to the first end of the substantially cylindrical member;

the track begins in the pin head and runs substantially helically through the first end and along a perimeter of the substantially cylindrical member for a distance from the first end, and then runs coaxially with the substantially cylindrical member along its perimeter to a point proximate the second end of the substantially cylindrical member; and

the at least one dimple is disposed within the track.

10. The pin device of claim 9, wherein the pin head is approximately the same diameter as the substantially cylindrical portion.

11. The device of claim 9, wherein the helical portion of the track travels between approximately 65 degrees and approximately 115 degrees about the circumference of the substantially cylindrical member.

12. The device of claim 9, wherein the helical portion of the track travels between approximately 155 degrees and approximately 205 degrees about the circumference of the substantially cylindrical member.

13. The device of claim 9, wherein the at least one dimple is disposed on the bottom surface of said track.

14. The device of claim 9, wherein a first dimple is disposed within the track proximate the first end of the substantially cylindrical member and a second dimple is disposed within the track proximate the second end of the substantially cylindrical member.
