Mechanism for attachment of accessories to gun

Abstract

A system for attaching and stabilizing a gun attachment accessory to the frame of a firearm in which the firearm frame has two parallel lateral rails running longitudinally along the length of the firearm frame and a one groove in the bottom of the firearm barrel frame positioned between and perpendicular to the lateral rails. A gun attachment accessory mounted to the frame via the lateral rails features a protrusion located on the upper surface of an accessory that is equipped with means to extend the protrusion such that it engages with the groove in the bottom of the firearm frame. The means to extend the protrusion such that it engages with the groove include a thumb screw possibly equipped with a compression spring, threaded through a bore such that the turning of the screw raises or lowers a platform featuring the protrusion.

I claim: 
     
         1 . A system for attaching a component to a firearm having a barrel frame, the system comprising
 a first lateral rail extending longitudinally along the bottom of the firearm barrel frame;   a second lateral rail extending longitudinally along the bottom of the firearm barrel frame, this second rail being spaced from and parallel to the first rail;   at least one groove in the bottom of the firearm barrel frame positioned between and perpendicular to the first and second parallel lateral rails extending longitudinally along the bottom of the firearm barrel frame;   a first lateral channel feature on the component to be attached to the firearm, the channel configured to compliment and interlock with the first lateral rail along the bottom of the firearm barrel frame;   a second lateral channel feature on the component to be attached to the firearm, the channel configured to compliment and interlock with the second lateral rail along the bottom of the firearm barrel frame;   a protrusion feature on the component to be attached to the firearm, the protrusion being configured to compliment and interlock with at least one groove in the bottom of the firearm barrel frame positioned between and perpendicular to the first and second parallel lateral rails extending longitudinally along the bottom of the firearm barrel frame, the protrusion being positioned between the first channel and the second channel; and   means whereby the protrusion feature on the component to be attached to the firearm may be manually adjusted so as to extend or retract the protrusion.   
     
     
         2 . The system of  claim 1  wherein the means for manually adjusting the protrusion feature on the component to be attached to the firearm is a mechanism comprising
 a threaded bore through the center of the component, the bore having a first end and a second end with the protrusion feature being positioned at the second end of the bore; 
 a threaded screw complimentary to the threads of the bore that may advance or retreat through the bore by the clockwise or counter-clockwise turning of the screw, the head of the screw being at the first end of the bore; and 
 means whereby the screw engages the protrusion feature such that the protrusion is extended outward from the body of the component when the screw is advanced through the bore, and the protrusion is retracted to the body of the component when the screw is retreated through the bore. 
 
     
     
         3 . The system of  claim 2  wherein the screw is a thumb screw. 
     
     
         4 . The system of  claim 1  wherein the protrusion feature is a platform having at least one protrusion on one surface of the platform. 
     
     
         5 . The system of  claim 2  wherein the protrusion feature is a platform having at least one protrusion on one surface of the platform. 
     
     
         6 . The system of  claim 3  wherein the protrusion feature is a platform having at least one protrusion on one surface of the platform. 
     
     
         7 . A system for attaching a component to a firearm having a barrel frame, the system comprising
 a first lateral rail extending longitudinally along the bottom of the firearm barrel frame;   a second lateral rail extending longitudinally along the bottom of the firearm barrel frame, this second rail being spaced from and parallel to the first rail;   at least one groove in the bottom of the firearm barrel frame positioned between and perpendicular to the first and second parallel lateral rails extending longitudinally along the bottom of the firearm barrel frame;   a first lateral channel feature on the component to be attached to the firearm, the channel configured to compliment and interlock with the first lateral rail along the bottom of the firearm barrel frame;   a second lateral channel feature on the component to be attached to the firearm, the channel configured to compliment and interlock with the second lateral rail along the bottom of the firearm barrel frame;   a protrusion feature on the component to be attached to the firearm, the protrusion feature comprising a platform having at least one protrusion on one surface of the platform, and the protrusion being configured to compliment and interlock with at least one groove in the bottom of the firearm barrel frame positioned between and perpendicular to the first and second parallel lateral rails extending longitudinally along the bottom of the firearm barrel frame, the protrusion feature being positioned between the first channel and the second channel;   a threaded bore through the center of the component, the bore having a first end and a second end with the protrusion feature being positioned at the second end of the bore;   a threaded thumb screw complimentary to the threads of the bore that may advance or retreat through the bore by the clockwise or counter-clockwise turning of the screw, the head of the screw being at the first end of the bore; and   means whereby the screw engages the protrusion feature such that the protrusion is extended outward from the body of the component when the screw is advanced through the bore, and the protrusion is retracted to the body of the component when the screw is retreated through the bore.
