Dual-speed elevation turret for rifle scopes

Abstract

A turret for mounting on a rifle scope, e.g. for elevation adjustment, may comprise dual adjustment mechanisms. A course adjustment may provide long range adjustment of a reticle position within a single turn of the course adjustment. A fine adjustment may provide fine adjustment of the reticle position within a single turn of the fine adjustment. Each of the course adjustment and the fine adjustment may be provided with click-stop arrangements for audible and tactile feedback of the adjustment mechanisms.

What is claimed is: 
     
         1 . A turret for a riflescope comprising:
 (A) a base for connecting the turret to the riflescope;   (B) a course adjustment supported within the base, the course adjustment comprising a first screw thread comprising a first screw pitch;   (C) a fine adjustment supported within the base, the fine adjustment comprising a second screw thread comprising a second screw pitch that is finer than the first screw pitch; and   (D) a reticle engagement component that engages at least one of the course adjustment and fine adjustment;   (E) wherein actuation of the course adjustment and the fine adjustment causes movement of the reticle engagement component.   
     
     
         2 . The turret of  claim 1  wherein the course adjustment is rotationally mounted within the base. 
     
     
         3 . The turret of  claim 2  comprising a course adjust movement piece that is rotationally linked to the course adjustment. 
     
     
         4 . The turret of  claim 3  comprising a first click-stop arrangement between the course adjust movement piece and the base. 
     
     
         5 . The turret of  claim 2  wherein the fine adjustment is rotationally mounted within the course adjustment. 
     
     
         6 . The turret of  claim 5  wherein rotation of the course adjustment relative to the base also rotates the fine adjustment. 
     
     
         7 . The turret of  claim 5  comprising a fine adjust movement piece that is rotationally linked to the fine adjustment. 
     
     
         8 . The turret of  claim 7  comprising a second click stop arrangement between the fine adjust movement piece and the course adjust movement piece. 
     
     
         9 . The turret of  claim 1  comprising a limiter for limiting the rotational range of the fine adjustment with respect to the course adjustment. 
     
     
         10 . The turret of  claim 9  wherein the fine adjustment is limited to a rotational range of less than 360 degrees for a fixed position of the course adjustment. 
     
     
         11 . A turret for a riflescope comprising:
 (A) base means for connecting the turret to the riflescope;   (B) reticle engagement means for engaging with a reticle of the riflescope;   (C) course adjustment means for course movement of the reticle engagement means; and   (D) fine adjustment means for fine movement of the reticle engagement means.   
     
     
         12 . The turret of  claim 11  wherein the course adjustment means is rotationally mounted within the base means. 
     
     
         13 . The turret of  claim 12  comprising course adjust movement means for rotating the course adjustment means. 
     
     
         14 . The turret of  claim 13  comprising first click-stop means between the course adjust movement means and the base means. 
     
     
         15 . The turret of  claim 12  wherein the fine adjustment means is rotationally mounted within the course adjustment means. 
     
     
         16 . The turret of  claim 15  comprising fine adjust movement means for rotating the fine adjustment means. 
     
     
         17 . The turret of  claim 16  comprising second click stop means between the fine adjust movement means and the course adjust movement means. 
     
     
         18 . The turret of  claim 11  comprising limiter means for limiting the rotational range of the fine adjustment means with respect to the course adjustment means.
