Front sight night vision device

Abstract

A night vision device to mark the location of a front sight on a rifle or a modern bow includes a casing, a power source and a light emission device adapted to the front sight. Wherein, the casing contains the power source connected to the light emission device, and a light conductor is further provided to the front of the light emission device so to mark the location of the front sight to aim at a selected target by the light emitted from the light emission device during night hours or where poor visual contact presents.

1 . A night vision device to mark the location of a front sight comprising a casing, a power source, and a light emission device adapted to the front sight having a light conductor located on a front end of the light emission device to conduct the light emitted by the light emission device to the front sight; wherein, the casing includes a tube and a switch set, the tube containing the power source connected to the light emission device; and the switch set controls conduction to the light emission device to mark by the light emitted from the light emission device the location of the front sight during night hours or where the visual contact is poor.  
     
     
         2 - 5 . (canceled).  
     
     
         6 . The night vision device to mark the location of a front sight as claimed in claim  2 , wherein, the light conductor is an optical fiber.  
     
     
         7 . The night vision device to mark the location of a front sight as claimed in claim  2 , wherein, the light conductor is an optical fiber wrapped up with a protection tube.  
     
     
         8 . A night vision device to mark the location of a front sight as claimed in  claim 7 , wherein, the protection tube wrapping up the optical fiber of the conductor is comprised of a flexible section connected to a rigid section.
