Adjustable spent cartridge casing deflector

Abstract

An adjustable spent cartridge casing deflector includes a deflector body directly attached on the firearm; wherein the deflector body includes a front side having a deflecting surface facing an expected trajectory of spent cartridge casings and being near an ejection port; wherein the deflector body is rotatably arranged on the firearm via an adjustable axis to adjust a direction of the deflecting surface; wherein the adjustable axis is configured to be rotated for selectively tightening or untightening the deflector body mounted on the firearm.

1 . An adjustable spent cartridge casing deflector, comprising:
 a deflector body directly attached on a firearm; wherein the deflector body comprises a front side having a deflecting surface facing an expected trajectory of spent cartridge casings and being near an ejection port;   wherein the deflector body is rotatably arranged on the firearm via an imaginary adjustable axis to adjust a direction of the deflecting surface; wherein the imaginary adjustable axis is configured to be rotated for selectively tightening or untightening the deflector body mounted on the firearm;   wherein the firearm further comprises a guiding track and the deflector body is arranged within the guiding track, and the guiding track comprises a first curved track which matches with a contour of the rear edge and a second curved track which matches with a contour of the front edge.   
     
     
         2 . The deflector of  claim 1 , wherein the deflecting surface defines a front edge directly attached to a firearm. 
     
     
         3 . (canceled) 
     
     
         4 . The deflector of  claim 2 , wherein the deflector body further comprises a rear side having a rear edge directly attached to the firearm and the rear edge is opposite of the front edge. 
     
     
         5 . The deflector of  claim 2 , wherein the ejection port comprises a top edge defining a top extending line extending towards the deflector body to form an adjustable angle with respect to a front extending line extending from the front edge. 
     
     
         6 . The deflector of  claim 5 , wherein the deflector body is counterclockwise rotated to enlarge the adjustable angle. 
     
     
         7 . Th deflector of  claim 5 , wherein the deflector body is clockwise rotated to reduce the adjustable angle. 
     
     
         8 . The deflector of  claim 1 , wherein the deflector body further comprises a through hole extending through the deflector body and the imaginary adjustable axis is embedded therein. 
     
     
         9 . The deflector of  claim 1 , wherein the deflector body is a triangular prism. 
     
     
         10 . The deflector of  claim 1 , wherein the deflecting surface is an angled surface. 
     
     
         11 . The deflector of  claim 4 , wherein the rear side further comprises a retaining surface integrally extended from the deflecting surface to form an acute angle. 
     
     
         12 . The deflector of  claim 11 , wherein the retaining surface is an angled surface. 
     
     
         13 . The deflector of  claim 1 , wherein the deflector body further comprises a left surface and a right surface, and the deflecting surface is integrally extended between the left surface and the right surface. 
     
     
         14 . The deflector of  claim 13 , wherein the deflector body further comprises a front surface integrally extended between the left surface and the right surface and opposite of a retaining surface. 
     
     
         15 . (canceled) 
     
     
         16 . The deflector of  claim 1 , wherein the front edge and the rear edge are slidable along the guiding track to control a rotation of the deflector body. 
     
     
         17 . (canceled) 
     
     
         18 . The deflector of  claim 4 , further comprising a right surface and a left surface, wherein the right and left surfaces are configured to define a thickness of the deflector body, wherein the thickness near the front edge is greater than the thickness near the rear edge. 
     
     
         19 . The deflector of  claim 11 , wherein the retaining surface further comprises a through hole extending through the deflector body and the imaginary adjustable axis is embedded therein. 
     
     
         20 . (canceled)
