Multi-dot reflex sight

Abstract

The disclosed subject matter relates to a reflex sight or another suitable dot sight having a viewing element upon which an illuminated reticle is projected, causing the illuminated reticle to be superimposed over the field of view at infinity. The illuminated reticle can comprise multiple aiming elements (e.g., dots) that are vertically aligned. A spacing between the vertically aligned aiming elements can be a function of a projectile trajectory, a function of a configuration of different projectile devices, or some other suitable function.

         7 . The sight apparatus of  claim 1 , further comprising a zeroing element that, in response to an adjustment to the zeroing element, is configured to change a location at which the illuminated reticle is projected onto the viewing element. 
     
     
         8 . The sight apparatus of  claim 7 , wherein the zeroing element comprises a vertical adjustment element that, in response to adjustment, moves the illuminated reticle vertically with respect to the viewing element. 
     
     
         9 . The sight apparatus of  claim 7 , wherein the zeroing element comprises a horizontal adjustment element that, in response to adjustment, moves the illuminated reticle horizontally with respect to the viewing element. 
     
     
         10 . The sight apparatus of  claim 1 , wherein the input is representative a defined projectile velocity and the spacing adjustment element changes the spacing distance as a function of a trajectory determined for a projectile. 
     
     
         11 . The sight apparatus of  claim 1 , wherein the input is representative of a projectile device model identification and the spacing adjustment element changes the spacing distance accordingly. 
     
     
         12 . The sight apparatus of  claim 11 , wherein the projectile has a first set of defined characteristics and is for a projectile device having a second set of defined characteristics, and wherein the respective spacing distance is increased or decreased in accordance with different ones of the first set of defined characteristics or the second set of defined characteristics. 
     
     
         13 . The sight apparatus of  claim 1 , wherein the reflecting material is at least partially transparent. 
     
     
         14 . The sight apparatus of  claim 1 , wherein the reflecting material is at least partially reflecting. 
     
     
         15 . The sight apparatus of  claim 1 , wherein the reflecting material comprises glass. 
     
     
         16 . The sight apparatus of  claim 1 , further comprising an adapter bracket configured to couple the sight apparatus to a projectile device. 
     
     
         17 . The sight apparatus of  claim 1 , wherein the adapter bracket comprises a picatinny rail element configured to couple to a picatinny groove element of the sight apparatus. 
     
     
         18 . The sight apparatus of  claim 1 , wherein the adapter bracket comprises a picatinny rail element configured to couple to a picatinny groove element of the sight apparatus. 
     
     
         19 . A sight apparatus, comprising:
 a viewing element comprising a reflecting material configured to present an illuminated reticle superimposed over a field of view visible when looking through the viewing element;   a projection element that projects the illuminated reticle onto the viewing element, wherein the illuminated reticle comprises multiple dots that are vertically aligned, and wherein a spacing distance between two of the multiple dots is a function of a trajectory determined for a first defined projectile; and   a spacing adjustment element that is configured to change the spacing distance in response to input indicating a second defined projectile that has different characteristics than the first defined projectile.   
     
     
         20 . A sight apparatus, comprising:
 a viewing element comprising a reflecting material configured to present an illuminated reticle superimposed over a field of view visible when looking through the viewing element;   a projection element that projects the illuminated reticle onto the viewing element, wherein the illuminated reticle comprises multiple dots that are vertically aligned, and wherein a spacing distance between two of the multiple dots is a function of a trajectory determined for a first defined projectile device; and   an adjustment element configured to change the spacing distance in response to input indicating a second defined projectile device that has different characteristics then the first defined projectile device.
