Quick-release gun lock

Abstract

A Quick-release Gun Lock is disclosed. The gun lock comprises a base that cooperates with the gun's extractor, a pliable and expandable portion attached to the base for expanding to create an interference fit with the gun's bore, and a compression shaft that, when rotated, will force the expandable portion outwardly to create the interference fit. The device may further include a cam hub that interacts with the compression shaft to provide the desired interference fit with less than one rotation.

What is claimed is:  
     
         1 . A lock for firearms, said firearms comprising a chamber having inner walls, a recoiling slide and at least one extracting finger attached to said slide, said lock comprising: 
 a base engageable with at least one said extracting finger;    at least one expandable portion adjacent to said base, each said expandable portion being expandable to engage said walls to prevent said slide from recoiling; and    a compression shaft in engagement with said base and said expandable portion to compress said expandable portion.    
     
     
         2 . The lock of  claim 1 , wherein: 
 said lock is further comprised by at least one said expandable portion comprising an expandable section formed from at least two expansion members separated by at least one domed washer, said expandable section is further defined by a base end and an opposing tip end, said base end being adjacent to said base; and    said lock further comprises a compression head adjacent to said tip end and in cooperation with said compression shaft to compress said expandable portion.    
     
     
         3 . The lock of  claim 1 , wherein: 
 said expandable portion comprises a socket formed therein and at least one retractable ball bearing members retained therein; and    said lock further comprises a core member formed to be accepted within said socket to cooperate with said one or more retractable ball bearing members;    whereby pressing said core member into said socket forces said retractable ball bearing members into to said chamber walls or said barrel walls.    
     
     
         4 . The lock of  claim 1 , wherein: 
 said base is further comprises with at least one channel formed therein; and    said expandable portion comprises at least one finger member, each said finger member comprising an elongate member received within one said channel.    
     
     
         5 . The lock of  claim 4 , wherein: 
 said finger members each further comprise a tip, said tips configured to expand into said chamber or barrel walls when said compression shaft exerts pressure against each said finger member.    
     
     
         6 . The lock of  claim 5 , wherein: 
 said base defines a center longitudinal axis and a radial direction, and each said channel is aligned to extend along said longitudinal axis while sloping from said center an in a radial direction.    
     
     
         7 . The lock of  claim 6 , wherein said expandable portion comprises: 
 three finger members in substantially equal spaced relation around said base and each received within a said channel; and    a biasing member for retaining said finger members to said compression shaft.    
     
     
         8 . A lock for firearms, said firearms comprising a chamber having inner chamber walls and a barrel having inner barrel walls, a recoiling slide and at least one extracting finger attached to said slide, said lock comprising: 
 a base engageable with at least one said extracting finger;    at least one expandable portion adjacent to said base, each said expandable portion being expandable to engage said barrel walls to prevent said slide from recoiling; and    a compression shaft in engagement with said base and said expandable portion to compress said expandable portion.    
     
     
         9 . A lock for firearms, said firearms comprising a chamber having inner chamber walls and a barrel having inner barrel walls, said lock comprising: 
 a base insertible in said chamber;    at least one expandable portion adjacent to said base, each said expandable portion being expandable to engage said barrel walls whereby said base is located in said chamber and said expandable portion is in said barrel; and    a compression shaft in engagement with said base and said expandable portion to compress said expandable portion.    
     
     
         10 . A lock for firearms, said firearms comprising a chamber having inner chamber walls and a barrel having inner barrel walls, said lock comprising: 
 a base insertible in said chamber, said base further defined by a sloped face;    a head member adjacent to said base, said head member defined by a sloped face, said sloped face formed to cooperate with said sloped base face, whereby said base sloped face and said head member sloped face are substantially in contact with one another; and    a compression shaft in engagement with said base and said head member to slide said sloped faces against one another to compress said base and said head member into said chamber or said barrel.
