US12305946 - Tool-less takedown rod for pistol

The patent describes a recoil rod assembly for semi-automatic firearms that features a front and rear rod with a cylindrical protuberance and aperture allowing for rotation between coaxial and offset positions. This design facilitates tool-less takedown, enhancing the ease of disassembly and maintenance of the firearm.

Claim 1

1. A recoil rod assembly for a semi-automatic firearm, comprising: (a) a front rod portion having a front end, a rear end, and a longitudinal axis; (b) a rear rod portion having a front end, a rear end and a longitudinal axis, said rear rod portion having a substantially same cross-section as the front rod portion; (c) a cylindrical protuberance having a longitudinal axis disposed at one of the rear end of the front rod portion and the front end of the rear rod portion; (d) a cylindrical aperture having a longitudinal axis disposed at the other of the rear end of the front rod portion and the front end of the rear rod portion; (e) wherein at least one of the longitudinal axis of the cylindrical protuberance and the longitudinal axis of the cylindrical aperture is offset from the longitudinal axis of the rear rod portion; (f) a flange at the rear end of the rear rod portion to receive a recoil spring; and (g) wherein the cylindrical protuberance is disposed in the cylindrical aperture, wherein the longitudinal axis of the cylindrical protuberance and the longitudinal axis of the cylindrical aperture are coaxial; and (h) wherein the front rod portion is rotatable with respect to the rear rod portion about the coaxial longitudinal axes of the cylindrical protuberance and the cylindrical aperture from a first position wherein the longitudinal axis of the front rod portion is coaxial with the longitudinal axis of the rear rod portion to a second position wherein the longitudinal axis of the front rod portion is offset from the longitudinal axis of the rear rod portion, wherein a stepped surface on the rear end of the front rod is exposed. (a) a front rod portion having a front end, a rear end, and a longitudinal axis; (b) a rear rod portion having a front end, a rear end and a longitudinal axis, said rear rod portion having a substantially same cross-section as the front rod portion; (c) a cylindrical protuberance having a longitudinal axis disposed at one of the rear end of the front rod portion and the front end of the rear rod portion; (d) a cylindrical aperture having a longitudinal axis disposed at the other of the rear end of the front rod portion and the front end of the rear rod portion; (e) wherein at least one of the longitudinal axis of the cylindrical protuberance and the longitudinal axis of the cylindrical aperture is offset from the longitudinal axis of the rear rod portion; (f) a flange at the rear end of the rear rod portion to receive a recoil spring; and (g) wherein the cylindrical protuberance is disposed in the cylindrical aperture, wherein the longitudinal axis of the cylindrical protuberance and the longitudinal axis of the cylindrical aperture are coaxial; and (h) wherein the front rod portion is rotatable with respect to the rear rod portion about the coaxial longitudinal axes of the cylindrical protuberance and the cylindrical aperture from a first position wherein the longitudinal axis of the front rod portion is coaxial with the longitudinal axis of the rear rod portion to a second position wherein the longitudinal axis of the front rod portion is offset from the longitudinal axis of the rear rod portion, wherein a stepped surface on the rear end of the front rod is exposed.
