Abstract

An attachable combination trigger safety device having combination locks, a lock lever and a pressure point release. The device is inserted in a gun trigger housing to prevent accidental gun firing. A press pin engages a cam that rotates with the lock lever so that the lock lever cannot release the gun trigger. The combination locks prevent the press pin from disengaging the cam. The combination locks must be opened so that the press pin can be held disengaged from the cam, and so that the user can rotate the lock lever to an open position.

Claims

exact text as granted — not AI-modified
1 . A trigger safety device, comprising: 
 a pressure pin;    a cam, in communication with said pressure pin;    a lock lever, in communication with said cam; and    a trigger groove, in communication with said lock lever.    
   
   
       2 . The device of  claim 1 , wherein said pressure pin is cylindrical.  
   
   
       3 . The device of  claim 1 , wherein said cam is fixedly attached to said lock lever.  
   
   
       4 . The device of  claim 1 , wherein said trigger groove is arranged with said lock lever to sandwich a trigger.  
   
   
       5 . The device of  claim 1 , further comprising a first combination lock in communication with said pressure pin.  
   
   
       6 . The device of  claim 1 , further comprising a second combination lock in communication with said cam.  
   
   
       7 . The device of  claim 1 , wherein said pressure pin has a first groove.  
   
   
       8 . The device of  claim 7 , wherein said first groove goes around the circumference of said pressure pin.  
   
   
       9 . The device of  claim 1 , wherein said cam has a second groove.  
   
   
       10 . The device of  claim 9 , wherein said second groove disturbs the circumference of said cam.  
   
   
       11 . The device of  claim 1 , further comprising a flat at the point where said cam communicates with said pressure pin.  
   
   
       12 . The device of  claim 11 , wherein said flat only moves against said pressure pin in one direction.  
   
   
       13 . The device of  claim 1 , further comprising a clutch in communication with said pressure pin.  
   
   
       14 . The device of  claim 13 , wherein said clutch communicates with said pressure pin to prevent said pressure pin from engaging said cam.
