Thumb rest anti-rotation pin for a firearm
View Patent ↗An anti-rotation thumb rest providing advantages that allow for non-destructive and unobtrusive installation on firearms that would otherwise not be able to accommodate a thumb rests. The thumb rest may be constructed by attaching or manufacturing a long cylindrical pin onto the back side of a thumb rest, as to serve as a trigger pin, locking block pin, or other pin used for securing pistol components internally together, while also providing a typically rectangular, square, circular, or irregular shaped protrusion that serves as an anti-rotation stop for installation in a typically unused recess in the firearm's receiver, that was not expressly designed for installing components.
1. A firearm thumb rest assembly for use with a firearm comprising:
a thumb rest;
a bridge coupled to the thumb rest;
a pistol assembly pin (PAP) coupled and orthogonal to the bridge and adapted to secure components of the firearm together; and
an anti-rotation plug, coupled to the bridge proximally closer to the muzzle end of the pistol than the pistol assembly pin, and adapted to mate with a recess in a firearm receiver,
wherein the PAP and anti-rotation plug are adapted to prevent all rotation of the thumb rest with respect to the firearm.
2. The firearm thumb rest assembly of claim 1 , wherein the recess in the firearm receiver is a channel through the firearm receiver.
3. The firearm thumb rest assembly of claim 1 , wherein the recess is an indentation in the firearm receiver.
4. The firearm thumb rest assembly of claim 1 , wherein the bridge is an integral part of the thumb rest.
5. The firearm thumb rest assembly of claim 1 , the PAP comprising a plurality of retaining grooves.
6. A firearm thumb support comprising:
a base;
a bridge couple to the base;
an elongated pin generally perpendicular to the bridge adapted to secure components of a firearm internally through the transverse axis of a receiver of the firearm; and
a protruding component, proximally closer to the muzzle end of the pistol than the elongated pin, generally perpendicular to the bridge and adapted to secure the firearm thumb support in a fixed position with respect to the firearm-when inserted into a recess in the firearm receiver;
wherein the elongated pin and protruding component are adapted to prevent all rotation of the firearm thumb support with respect to the firearm.
7. The firearm thumb support of claim 6 , wherein the recess in the firearm receiver is a channel through the firearm receiver.
8. The firearm thumb support of claim 6 , wherein the recess is an indentation in the firearm receiver.
9. The firearm thumb support of claim 6 , wherein the bridge is an integral part of the base.
10. The firearm thumb support of claim 6 , the elongated pin comprising a plurality of retaining grooves.
11. A firearm, comprising:
a receiver;
a thumb rest;
a bridge coupled to the thumb rest;
a pistol assembly pin (PAP) coupled and orthogonal to the bridge and adapted to secure components of the firearm together; and
an anti-rotation plug, coupled to the bridge proximally closer to the muzzle end of the pistol than the pistol assembly pin, and adapted to mate with a recess in a firearm receiver and to secure the firearm thumb rest assembly in a fixed position with respect to the firearm;
wherein the PAP and anti-rotation plug are adapted to prevent all rotation of the thumb rest with respect to the firearm.
12. The firearm of claim 11 , wherein the recess in the receiver is a channel through the receiver.
13. The firearm of claim 11 , wherein the recess is an indentation in the receiver.
14. The firearm of claim 11 , wherein the bridge is an integral part of the thumb rest.
15. The firearm of 11 , the PAP comprising a plurality of retaining grooves.
16. The firearm thumb rest assembly of claim 1 , wherein the PAP is a trigger pin.
17. The firearm thumb rest assembly of claim 1 , wherein the PAP is a locking block pin.
18. The firearm thumb support of claim 6 , wherein the elongated pin is a trigger pin.
19. The firearm thumb support of claim 6 , wherein the elongated pin is a locking block pin.
20. The firearm of claim 11 , wherein the PAP is a trigger pin.
21. The firearm of claim 11 , wherein the PAP is a locking block pin.
