Firearm for low velocity projectiles

Abstract

A firearm for low velocity projectiles has a barrel for launching the projectiles, and a fire control system. The fire control system comprises a sight having a longitudinal axis, sensors for sensing data of a target object, and first means for adjusting a line of sight of the sight relative to the longitudinal axis of the sight. The adjusting is effected by a predetermined angle as a function of the data. Further, second means are provided for adjusting the longitudinal axis of the sight relative to a bore axis of the barrel.

1 . A firearm for low velocity projectiles having a barrel for launching said projectiles, and a fire control system, said fire control system comprising: 
 a sight having a longitudinal axis;    sensors for sensing data of a target object;    first means for adjusting a line of sight of said sight relative to said longitudinal axis of said sight, said adjusting being effected by a predetermined angle as a function of said data; and    second means for adjusting said longitudinal axis of said sight relative to a bore axis of said barrel.    
   
   
       2 . The firearm of  claim 1 , wherein said first means adjust a reticle of said sight.  
   
   
       3 . The firearm of  claim 1 , wherein said second means effect a swivelling at least of optical components of said sight relative to said barrel.  
   
   
       4 . The firearm of  claim 3 , wherein said second means effect a swivelling of said sight as a whole relative to said barrel.  
   
   
       5 . The firearm of  claim 3 , wherein said second means effect a swivelling movement in predetermined angular steps.  
   
   
       6 . The firearm of  claim 5 , wherein said line of sight is adapted to be adjusted within a predetermined range, wherein, when said longitudinal axis of said sight is swivelled by an angular step from a first angular position to a second angular position, said predetermined range in said first angular position spatially overlaps said predetermined range in said second angular position.  
   
   
       7 . The firearm of  claim 1 , wherein during aiming said line of sight, said second means effect a course adjustment and, thereafter said first means effect a fine adjustment.  
   
   
       8 . The firearm of  claim 6 , wherein during aiming said line of sight, said second means effect a course adjustment and, thereafter said first means effect a fine adjustment and, when during said fine adjustment a predetermined adjustment threshold value is reached, said second means cause said first means to effect another angular step.  
   
   
       9 . The firearm of  claim 1 , wherein said first means and said second means effect an adjustment within a vertical plane.  
   
   
       10 . The firearm of  claim 1 , wherein said first means and said second means effect an adjustment within a horizontal plane.  
   
   
       11 . The firearm of  claim 1 , wherein said data comprise a distance between a target object and said firearm.  
   
   
       12 . The firearm of  claim 1 , wherein said data comprise an elevation of said line of sight between a target object and said firearm.  
   
   
       13 . The firearm of  claim 1 , wherein said data comprise a velocity of a target object relative to said firearm.  
   
   
       14 . The firearm of  claim 1 , wherein said first means are configured optical.  
   
   
       15 . The firearm of  claim 1 , wherein said first means are configured electronical.  
   
   
       16 . The firearm of  claim 1 , wherein said second means are configured essentially mechanical.
