Offset centerline barrel for a firearm simulator

Abstract

A barrel apparatus for non-permanent conversion of a firearm into a compressed gas powered firearm simulator for simulated shooting. The conversion barrel including a substantially tubular and sealingly contained compressed gas reservoir having a longitudinal centerline; a fill port for recharging the compressed gas reservoir; a striker having a longitudinal axis and adapted for longitudinal movement; a metering valve in the compressed gas reservoir actuated by the longitudinal movement of said striker. The longitudinal axis of the striker may be offset from the longitudinal centerline of the tubular compressed gas reservoir.

What is claimed is: 
     
         1 . A barrel apparatus for conversion of a firearm into a compressed gas-powered firearm simulator for simulated firing, the barrel apparatus comprising:
 a substantially tubular and sealingly contained compressed gas reservoir having a longitudinal centerline;   a fill port for recharging said compressed gas reservoir;   a striker;   said compressed gas reservoir including a metering valve adapted for actuation by said striker to release an amount of gas sufficient to simulate firing of the firearm;   said striker being offset from said longitudinal centerline of said tubular compressed gas reservoir.   
     
     
         2 . The barrel apparatus of  claim 1  including a laser positioned adjacent said fill port. 
     
     
         3 . The barrel apparatus of  claim 2  wherein said laser is adapted for emitting a beam of light upon firing. 
     
     
         4 . A barrel apparatus for non-permanent conversion of a firearm into a compressed gas powered firearm simulator for simulated firing of a shot, comprising:
 a substantially tubular and sealingly contained compressed gas reservoir having a longitudinal centerline;   a fill port in fluid communication with said reservoir for recharging said compressed gas reservoir;   a striker having a longitudinal axis and adapted for longitudinal movement;   said compressed gas reservoir having a metering valve actuated by said longitudinal movement of said striker;   said longitudinal axis of said striker being offset from said longitudinal centerline of said tubular compressed gas reservoir.   
     
     
         5 . The barrel apparatus of  claim 4  wherein said compressed gas reservoir includes a first end and a second end and said fill port is sealingly secured to said second end of said compressed gas reservoir. 
     
     
         6 . The barrel apparatus of  claim 5  wherein said fill port is threaded into said second end of said compressed gas reservoir. 
     
     
         7 . The barrel apparatus of  claim 4  further including an eccentric segment secured to said first end of said compressed gas reservoir. 
     
     
         8 . The barrel apparatus of  claim 7  wherein said eccentric segment is threaded into said first end of said compressed gas reservoir. 
     
     
         9 . The barrel apparatus of  claim 4  including a laser positioned adjacent said fill port. 
     
     
         10 . The barrel apparatus of  claim 9  wherein said laser is adapted for emitting a beam of light upon the firing of the simulated shot. 
     
     
         11 . The barrel apparatus of  claim 4  wherein the firearm includes a frame, comprising:
 a block for securing said compressed gas reservoir to the frame. 
 
     
     
         12 . The barrel apparatus of  claim 11  including a sleeve having an inner cylindrical surface which fastens said block to said compressed gas reservoir and wherein said inner cylindrical surface serves as a functional bore to receive a reciprocating piston.
