Barrel lock for a hand gun

For a gun having a barrel and a bullet chamber communicating with the barrel for receiving a bullet to be fired through the barrel, a gun barrel lock to be removably inserted in the barrel and releasably retained at the bullet chamber to prevent the firing of the gun, said gun barrel lock comprising:

• a barrel lock tube having proximal and distal ends and being sized to slide through the barrel of the gun;
• a hollow chamber located at the distal end of said barrel lock tube to be received in and releasably retained at the bullet chamber when said barrel lock tube slides inwardly through the gun barrel so as to prevent a bullet from entering the bullet chamber, said hollow chamber manufactured from a flexible material having a spring like memory and adapted to expand from a relatively narrow size to a relatively wide size to fill the bullet chambers and thereby disable the gun;
• a barrel lock rod surrounded by said barrel lock tube and having a proximal end, a distal end and expansion force generating means located at the distal end of said barrel lock rod, said barrel lock rod moving in a proximal direction relative to said barrel lock tube to locate said expansion force generating means within the hollow chamber of said barrel lock tube to cause said hollow chamber to expand to said relatively wide size in order to fill the bullet chamber and thereby prevent said barrel lock tube from sliding outwardly through the gun barrel, and said barrel lock rod moving in a distal direction relative to said barrel lock tube to remove said expansion force generating means from the hollow chamber of said barrel lock tube in order to allow said hollow chamber to contract to said relatively narrow size so that said barrel lock tube can slide outwardly through the gun barrel;
• lock means having a moveable lock shaft that communicates with the proximal end of said barrel lock rod, said lock means being disposed in a locked condition to block the movement of said lock shaft whereby to prevent said barrel lock rod from moving in said distal direction relative to said barrel lock tube and said barrel lock tube from sliding outwardly through the gun barrel;
• and
• force transmitting means coupled to said barrel lock rod via the lock shaft of said lock means, said lock shaft being moved towards said barrel lock rod when said lock means is disposed in an unlocked condition and a distal pushing force is applied to said force transmitting means to cause said barrel lock rod to move in said distal direction relative to said barrel lock tube and permit said barrel lock tube to slide outwardly through the gun barrel.
