Latched charging handle with mechanical advantage separator
Charging handles having a mechanical advantage separator for separating an end of the charging handle from a portion of a firearm are disclosed. Specifically, charging handles having a simple machine, such as a lever, are disclosed. Advantageously, the simple machine can multiply the force applied by a user on the charging handle. Additionally, in at least some instances, the simple machine will actuate a charging handle latch so as to disengage the charging handle latch from a receiver of the firearm.
1. A device for moving a charging handle of a firearm rearward, comprising: a rearward-assist member arranged to provide a mechanical advantage to increase a force applied to the rearward-assist member and apply that increased force to a housing of the firearm to move an end of a charging handle base away from the housing when a charging handle latch of the charging handle is disengaged from the firearm.
2. The device of claim 1 , wherein:
the rearward-assist member comprises a pivoting charging handle removal lever having three separate locations to achieve a mechanical advantage:
(a) a first location which engages the charging handle base or the charging handle latch,
(b) a second location which engages the firearm, and
(c) a third location exposed for application of manual force and positioned to achieve a mechanical advantage for releasing the charging handle when stuck in the firearm.
3. The device of claim 2 , wherein the first location comprises a lip that protrudes out-of-plane of the second location and the third location.
4. The device of claim 3 , wherein the lip is configured to interface with a forward surface of a charging handle base.
5. The device of claim 4 , wherein when the lip interfaces with the forward surface of a charging handle base a bottom surface of the pivoting charging handle removal lever rests upon a top surface of the charging handle base.
6. The device of claim 3 , wherein the lip has a curved periphery.
7. The device of claim 2 , wherein the first location is positioned between the second location and the third location.
8. The device of claim 7 , wherein the second location is positioned along a curved surface of the pivoting charging handle removal lever.
9. The device of claim 7 , wherein a distance between the first location and the second location is less than a distance between the first location and the third location.
10. The device of claim 7 , wherein the pivoting charging handle removal lever has a first portion extending from said third location to said first location and a second portion extending from said first location to said second location; and
wherein at said first location said first and second portions intersect to define an obtuse angle.
11. The device of claim 7 , wherein the first location comprises a lip that protrudes out-of-plane of the second location and the third location.
12. The device of claim 11 , wherein the lip is configured to interface with a forward surface of a charging handle base.
13. The device of claim 12 , wherein when the lip interfaces with the forward surface of a charging handle base a bottom surface of the pivoting charging handle removal lever rests upon a top surface of the charging handle base.
14. The device of claim 13 , wherein the second location is positioned along a curved surface of the pivoting charging handle removal lever.
15. The device of claim 14 , wherein the pivoting charging handle removal lever has a first portion extending from said third location to said first location and a second portion extending from said first location to said second location; and
wherein at said first location said first and second portions intersect to define an obtuse angle.
16. The device of claim 15 , wherein the pivoting charging handle removal lever is removable from the changing handle base without the use of a tool.
17. The device of claim 11 , wherein the lip has a curved periphery.
18. The device of claim 2 , wherein a distance between the first location and the second location is less than a distance between the first location and the third location.
19. The device of claim 2 , wherein the pivoting charging handle removal lever is removable from the changing handle base without the use of a tool.
