Sliding sheath type fixture for pistol accessory

Abstract

A fixture attaches a pistol accessory to a pistol. The fixture has a seat having a holding hole for retaining the pistol accessory, the seat having a generally U-shaped body with two flank sides connected by a bottom surface, and with each flank side having an inner surface and a fixing hole. The seat further includes a sliding track disposed on the inner surface of each flank side, with each sliding track slidable along one of the longitudinal grooves along the bottom edge of the pistol barrel. The fixture also includes a fixing rod extending through the fixing holes in the two flank sides, and an elastic mechanism provided adjacent the bottom surface of the seat and engaging the fixing rod to bias the fixing rod into a transverse groove at the bottom edge of the pistol when the fixture is attached to the pistol.

         1 . A fixture for attaching a pistol accessory to a pistol, the pistol having a pistol barrel that has a bottom edge, with a pair of longitudinal grooves provided along the bottom edge, and a transverse groove extending between the longitudinal grooves at the bottom edge at a predetermined location, the fixture comprising: 
 a seat having a holding hole for retaining the pistol accessory, the seat having a generally U-shaped body with two flank sides connected by a bottom surface, each flank side having an inner surface and a fixing hole, the seat further having a sliding track disposed on the inner surface of each flank side, with each sliding track slidable along one of the longitudinal grooves;    a fixing rod extending through the fixing holes in the two flank sides; and    an elastic mechanism provided adjacent the bottom surface of the seat and engaging the fixing rod to bias the fixing rod into the transverse groove of the pistol when the fixture is attached to the pistol.    
     
     
         2 . The fixture of  claim 1 , wherein the fixing rod has an inner side, and an inclined plane provided along the inner side.  
     
     
         3 . The fixture of  claim 1 , wherein the fixing rod has an outer side, and a two-sided wedging surface provided on the outer side and engaging the transverse groove of the pistol.  
     
     
         4 . The fixture of  claim 1 , wherein the fixing rod has a bottom side, and a groove provided on the bottom side of the fixing rod for receiving the elastic mechanism.  
     
     
         5 . The fixture of  claim 1 , wherein the elastic mechanism is a plastic plate.  
     
     
         6 . The fixture of  claim 1 , wherein the elastic mechanism is a plastic spring.  
     
     
         7 . The fixture of  claim 1 , wherein the elastic mechanism further includes a fulcrum element that engages the bottom edge of the pistol.  
     
     
         8 . The fixture of  claim 7 , wherein the fulcrum element is an elastic plate.  
     
     
         9 . The fixture of  claim 1 , further including a longitudinal groove in the bottom surface of the U-shaped body in which the elastic mechanism is retained.  
     
     
         10 . The fixture of  claim 1 , wherein the seat further includes a clamping ring that has a longitudinal slot that separates two flank sides, with a threaded hole provided in each of the flank sides of the clamping ring, and a bolt that is extended through the threaded holes in each of the flank sides of the clamping ring.  
     
     
         11 . An assembly, comprising: 
 a pistol having a pistol barrel that has a bottom edge, with a pair of longitudinal grooves provided along the bottom edge, and a transverse groove extending between the longitudinal grooves at the bottom edge at a predetermined location;    a pistol accessory; and    a fixture comprising: 
 a seat having a holding hole for retaining the pistol accessory, the seat having a generally U-shaped body with two flank sides connected by a bottom surface, each flank side having an inner surface and a fixing hole, the seat further having a sliding track disposed on the inner surface of each flank side, with each sliding track slidable along one of the longitudinal grooves;  
 a fixing rod extending through the fixing holes in the two flank sides; and  
 an elastic mechanism provided adjacent the bottom surface of the seat and engaging the fixing rod to bias the fixing rod into the transverse groove of the pistol when the fixture is attached to the pistol.  
   
     
     
         12 . The assembly of  claim 11 , wherein the fixing rod has an inner side, and an inclined plane provided along the inner side.  
     
     
         13 . The assembly of  claim 11 , wherein the fixing rod has an outer side, and a two-sided wedging surface provided on the outer side and engaging the transverse groove of the pistol.  
     
     
         14 . The assembly of  claim 11 , wherein the fixing rod has a bottom side, and a groove provided on the bottom side of the fixing rod for receiving the elastic mechanism.  
     
     
         15 . The assembly of  claim 11 , wherein the elastic mechanism is a plastic plate.  
     
     
         16 . The assembly of  claim 11 , wherein the elastic mechanism is a plastic spring.  
     
     
         17 . The assembly of  claim 11 , wherein the elastic mechanism further includes a fulcrum element that engages the bottom edge of the pistol.  
     
     
         18 . The assembly of  claim 17 , wherein the fulcrum element is an elastic plate.  
     
     
         19 . The assembly of  claim 11 , further including a longitudinal groove in the bottom surface of the U-shaped body in which the elastic mechanism is retained.  
     
     
         20 .
