Method and device for providing an integral firearms safety lock mechanism

Abstract

The present invention provides an integral firearms safety lock that safely provides locking capabilities in a firearm. The integral firearms safety lock ensures that a firearm is unable to fire by a simple manual manipulation of a locking mechanism. Moreover, an integral firearms safety lock is provided that contacts and locks a firing pin safety thereby preventing any unauthorized firing of the firearm.

1 . A method for locking a firearm so as to be unable to fire, comprising:
 inserting a tool into an end of a locking shaft located in the firearm;   using the tool, rotating the locking shaft from an unlocked position to a locked position wherein a radial portion of the locking shaft rotates into a groove located in a firing firing pin safety, wherein in the locked position, the locking shaft contacts the firing pin safety to prevent movement of the firing pin safety; and   removing the tool from the end of the locking shaft.   
   
   
       2 . The method of  claim 1 , wherein the rotation of the locking shaft further causes a change in the location of a detent pin, in contact with the locking shaft, from a first detent to a second detent on the locking shaft 
   
   
       3 . The method of  claim 1 , wherein the locking shaft and the detent pin are both integral to the firearm. 
   
   
       4 . The method of  claim 2 , wherein the detent pin contacts a detent pin spring that biases the detent pin against the locking shaft. 
   
   
       5 . The method of  claim 1 , wherein the locking shaft is rotated by 90 degrees to change the state of the firearm from an unlocked state to a locked state.
