Quick-acquisition optical sight with red-dot-indication function

Abstract

A quick-acquisition optical sight for short-distance aiming or viewing enhanced with an illuminated reticle, e.g., a red dot, and intended for installation on a conventional long-distance viewing apparatus, the combination thereof comprising an integral assembly consisting of a mounting part attachable directly to the tubular scope without any intermediate adapters and a housing with an optical system that is pivotally supported by the mounting part. In spite of the fact that the quick-acquisition sight is approximately 30% smaller and less heavy than the smallest existing sight of this type, it incorporates click-type mechanisms for adjusting the position of the sight optical axis relative to the optical axis of the scope.

1 . A quick-acquisition optical sight with a red-dot-indication function that has an optical axis and is intended for installation on a tubular optical scope having an optical axis, the quick-acquisition optical sight being installed on the tubular optical scope in a space within the limits of an allowable parallax between the optical axes of the quick-acquisition optical sight, the quick-acquisition optical sight comprising a single indivisible assembly that comprises a mounting part attachable directly to the attachment means on the tubular optical scope without use of additional adapters, and a sight housing that incorporates a click-type elevation-adjustment mechanism and a click-type windage-adjustment mechanism. 
   
   
       2 . The quick-acquisition optical sight of  claim 1 , wherein the mounting part has a distal end on the target side and a proximal end on the viewer side, the sight housing has a distal end on the target side that contains the optical lens and a proximal end on the viewer side, the distal end of the mounting part having a mechanism for pivotally attaching the distal end of the sight housing to the mounting part for pivotal movements of the sight housing relative to the mounting part and thus for vertical displacement of the optical axis of the quick-acquisition optical sight relative to the optical axis of the tubular optical scope. 
   
   
       3 . The quick-acquisition optical sight of  claim 2 , wherein the mechanism for pivotally attaching the distal end of the sight housing to the mounting part for pivotal movements of the sight housing relative to the mounting part comprises a transverse axis located at the distal end of the mounting part. 
   
   
       4 .

       5 . The quick-acquisition optical sight of  claim 3 , wherein said elevation adjustment mechanism comprising a first screw and a first nut engaged with the first screw, a first circular member attached to the first screw having circumferentially arranged projections and valleys on the periphery, and a first spring-loaded element that interacts with the projections and valleys of the first and produces a detectable click when the spring-loaded element falls into the valley of the first circular member. 
   
   
       6 . The quick-acquisition optical sight of  claim 3 , wherein said windage-adjustment mechanism comprises a second screw rotatingly installed in the sight housing, a second nut engaged with the second screw and supported by said transverse axis, a second circular member attached to the second screw having circumferentially arranged projections and valleys on the periphery, and a second spring-loaded element that interacts with the projections and valleys of the second circular member and produces a detectable click when the spring-loaded element falls into the valley of the second circular member. 
   
   
       7 . The quick-acquisition optical sight of  claim 1 , wherein the distance between the optical axis of the quick-acquisition optical sight and the optical axis of the tubular optical scope at the distal end of the quick-acquisition optical sight does not exceed 40 mm. 
   
   
       8 . The quick-acquisition optical sight of  claim 2 , wherein the distance between the optical axis of the quick-acquisition optical sight and the optical axis of the tubular optical scope at the distal end of the quick-acquisition optical sight does not exceed 40 mm. 
   
   
       9 . The quick-acquisition optical sight of  claim 3 , wherein the distance between the optical axis of the quick-acquisition optical sight and the optical axis of the tubular optical scope at the distal end of the quick-acquisition optical sight does not exceed 40 mm. 
   
   
       10 . The quick-acquisition optical sight of  claim 5 , wherein the distance between the optical axis of the quick-acquisition optical sight and the optical axis of the tubular optical scope at the distal end of the quick-acquisition optical sight does not exceed 40 mm.
