Barrel locking mechanism for a break-open-action firearm

Abstract

A barrel locking mechanism for a break-open-action firearm comprising a pivotally connected barrel section and receiver section, wherein the barrel locking mechanism comprises a barrel back plate secured to the receiver section, a spring loaded lever clip arm secured to the barrel section, and a spring loaded U-shaped lever arm secured to the receiver section, wherein the U-shaped lever arm secures the lever clip to the barrel back plate.

Having thus described the invention, what is claimed is: 
     
         1 . A barrel locking mechanism for a break-open-action firearm including a barrel section and a receiver section, the barrel locking mechanism comprises:
 (a) a barrel back plate fixedly secured to the receiver section, the barrel back plate comprising a first and second upward flange member extending upwardly from the barrel back plate, a ledge interconnecting the first and second upward flange members to form a first trough, a divot formed within the barrel back plate behind the ledge, and a first and second parabolic flange members extending toward and about the receiver section;   (b) a lever clip pivotally secured to the barrel section having a distal end and a proximal end; and   (c) a U-shaped lever arm pivotally secured to the receiver section for locking the lever clip to the barrel back plate, the U-shaped lever arm comprising a bight section and opposed side arms extending downward therefrom.   
     
     
         2 . The barrel locking mechanism of  claim 1  further comprising a pair of opposed pins for securing the U-shaped lever arm and barrel back plate to the receiver section. 
     
     
         3 . The barrel locking mechanism of  claim 2  further comprising a pair of opposed pin springs, each of the pin springs including a first end and a second end, each of the pin springs being wrapped around an associated pin of the pair of pins, the first end being situated against the barrel back plate, the second end being situated against an associated side arm of the U-shaped lever arm. 
     
     
         4 . The barrel locking mechanism of  claim 1  wherein the lever clip further comprises an upward protrusion extending upwardly from the distal end to thereby form a slope, the slope being angled upwardly toward the U-shaped lever arm, and a downward protrusion that extends downwardly from the distal end, the distal end of the lever clip extends through the first trough when the barrel section and receiver section are mated. 
     
     
         5 . The barrel locking mechanism of  claim 1  further comprising a lever spring disposed between the lever clip and the barrel section. 
     
     
         6 . The barrel locking mechanism of  claim 1  further comprising a third and fourth upward flange member extending upwardly from the barrel section forming a second trough, the lever clip being disposed within the second trough. 
     
     
         7 . The barrel locking mechanism of  claim 6  further comprising a biasing member extending through the lever spring and the second trough pivotally connecting the lever spring to the second trough. 
     
     
         8 . A break-open-action firearm comprising:
 (a) a receiver section including a bottom portion, a middle portion, and a top portion, the bottom portion further comprises a handle grip, a trigger guard, and a fifth flange member, the fifth flange member, the middle portion forms a base for securing the barrel back plate thereto, the top portion forms a mount for a visual apparatus;   (b) a barrel section including at least one barrel, the barrel comprising a medial axial bore formed therethrough, the barrel section further comprises a sixth and seventh flange member extending downwardly from the at least one barrel fitted about the fifth flange member;   (c) a roll pin extending through the fifth flange member of the receiver section and the sixth and seventh flange members of the barrel section thereby pivotally connecting the receiver section and barrel section; and   (d) a barrel locking mechanism comprising a barrel back plate fixedly secured to the receiver section, a lever clip pivotally secured to the barrel section, and a U-shaped lever arm pivotally secured to the receiver section for locking the lever clip to the barrel back plate;   (d) the barrel back plate comprising a first and second upward flange member extending upwardly from the barrel back plate, a ledge interconnecting the first and second upward flange members to form a first trough, a divot formed within the barrel back plate behind the ledge, and a first and second parabolic flange member extending toward and about the receiver section;   (e) the lever clip comprising a distal end and a proximal end; and   (f) the U-shaped lever arm comprises a bight section and opposed arms extending downward therefrom.   
     
     
         9 . The firearm of  claim 8  further comprising a pair of opposed pins for securing the U-shaped lever arm and barrel back plate to the receiver section. 
     
     
         10 . The firearm of  claim 9  further comprising a pair of opposed pin springs, each of the pin springs having a first end and a second end, each of the pin springs being wrapped around an associated pin of the pair of pins, the first end being situated against the barrel back plate, the second end being situated against an associated side arm of the U-shaped lever arm. 
     
     
         11 . The firearm of  claim 8  wherein the lever clip further comprises an upward protrusion extending upwardly from the distal end to form a slope, the slope being angled upwardly towards the U-shaped lever arm, and a downward protrusion that extends downwardly from the distal end, the distal end of the lever clip extends through the first trough when the barrel section and receiver section are mated. 
     
     
         12 . The firearm of  claim 8  further comprising a lever spring disposed between the lever clip and the barrel section. 
     
     
         13 . The firearm of  claim 8  further comprising a third and fourth upward flange member extending upwardly from the barrel section forming a second trough, the lever clip being disposed within the second trough. 
     
     
         14 . The firearm of  claim 13  further comprising a biasing member extending through the lever spring and the second trough pivotally connecting the lever spring to the second trough. 
     
     
         15 . The firearm of  claim 8  wherein the firearm is an over-under, double barreled, handheld, break-open-action projectile launcher.
