Extractor for firearms

Abstract

An extractor for a firearm. The extractor includes an extractor body, an edge at a first end of the extractor body, a pivot at a second end of the extractor body, opposite the first end, and a locking portion. The extractor edge is configured to engage a bullet casing. The pivot is configured to permit the extractor to pivot about a first axis and to pivot about a second axis that is orthogonal to the first axis when the extractor is installed within a firearm slide. The locking portion is configured to engage with a corresponding locking element in the firearm slide.

         21 . A firearm comprising:
 a frame;   a barrel coupled to the frame;   a slide or bolt comprising a locking element, wherein the slide or bolt is coupled to the frame; and   an extractor installed within the slide or bolt such that the extractor is free to move from an unlocked position to a locked position during an operation of the slide or bolt, the extractor comprising a locking portion that engages with the locking element when the extractor is in the locked position, thereby, preventing the extractor from moving during extraction of a cartridge casing from a chamber of the firearm.   
     
     
         22 . The firearm of  claim 21 , wherein the frame is a rifle frame. 
     
     
         23 . A firearm comprising:
 a frame;   a slide or bolt coupled to the frame; and   an extractor installed within the slide or bolt such that the extractor is free to move from an unlocked position to a locked position during an operation of the slide or bolt.   
     
     
         24 . The firearm of  claim 23 , wherein in the locked position, the extractor is prevented from moving during extraction of a cartridge casing from a chamber of the firearm. 
     
     
         25 . The firearm of  claim 23 , wherein in the unlocked position, the extractor is free to move during chambering of a cartridge into a chamber of the firearm. 
     
     
         26 . The firearm of  claim 23 , wherein the extractor is configured to transition from the unlocked position to the locked position during an extraction operation of the slide or bolt. 
     
     
         27 . The firearm of  claim 23 , wherein the extractor is configured to transition from the unlocked position to the locked position under recoil forces of the firearm. 
     
     
         28 . The firearm of  claim 23 , wherein the slide or bolt comprises a locking element, and
 wherein the extractor comprises a locking portion that engages with the locking element when the extractor is in the locked position.   
     
     
         29 . The firearm of  claim 28 , wherein the locking element comprises a channel in the slide or bolt. 
     
     
         30 . The firearm of  claim 28 , wherein the locking portion comprises a protrusion from a surface of the extractor, the protrusion shaped to engage with the locking element. 
     
     
         31 . The firearm of  claim 23 , further comprising an extractor spring installed within the slide or bolt and in contact with the extractor so as to apply a bias force to the extractor. 
     
     
         32 . A firearm cartridge extraction system comprising:
 a slide or bolt; and   an extractor configured to be installed within the slide or bolt such that the extractor is free to move from an unlocked position to a locked position during an operation of the slide or bolt.   
     
     
         33 . The system of  claim 32 , wherein in the locked position, the extractor is prevented from moving during extraction of a cartridge casing from a chamber of the firearm. 
     
     
         34 . The system of  claim 32 , wherein in the unlocked position, the extractor is free to move during chambering of a cartridge into a chamber of the firearm. 
     
     
         35 . The system of  claim 32 , wherein the extractor is configured to transition from the first position to the second position during an extraction operation of the slide or bolt. 
     
     
         36 . The system of  claim 32 , wherein the extractor is configured to transition from the unlocked position to the locked position under recoil forces of the firearm. 
     
     
         37 . The system of  claim 32 , wherein the slide or bolt comprises a locking element, and
 wherein the extractor comprises a locking portion that engages with the locking element when the extractor is in the locked position.   
     
     
         38 . The system of  claim 37 , wherein the locking element comprises a channel in the slide or bolt. 
     
     
         39 . The system of  claim 37 , wherein the locking portion comprises a protrusion from a surface of the extractor, the protrusion shaped to engage with the locking element. 
     
     
         40 . The system of  claim 32 , further comprising an extractor spring installed within the slide or bolt and in contact with the extractor so as to apply a bias force to the extractor.
