Moving pin archery sight

Abstract

A moving pin archery sight that includes a ratio adjustment mechanism for allowing a user to varying the ratio of movement between the user adjustment end of the sight holder slide positioning arm and the sight holder slide to mechanically compensate the moving pin archery sight for use with particular arrow speeds generated by particular bow and arrow combinations and/or different arrows with the same bow.

What is claimed is:  
     
         1 . In a moving pin archery sights having a sight pin mounted to a sight in mechanical connection with a sight pin positioning mechanism that includes a positioning mechanism frame securable to an archery bow, a sight holder slide that is movable upward and downward along a predefined vertical trackway of the positioning mechanism frame, a pivoting, sight holder slide positioning arm pivotally connected at a pivot point to the positioning mechanism frame and mechanically linked along a slide connecting end portion thereof to the sight holder slide such that, as a user adjustment end of the pivoting sight holder slide positioning arm moves along an arcuate path in a substantially first direction, the sight holder slide moves along a straight path in a second direction substantially opposite the first direction, the pivot point being between the user adjustment end and the slide connecting end portion; the sight being carried on the sight holding slide; each angular position of the user adjustment end of the pivoting sight holder slide positioning arm indicating a different distance to a target such that a user may adjust the position of the sight pin of the sight to correspond with a particular distance to a target by moving the user adjustment end of the pivoting sight holder slide positioning arm to the particular angular position corresponding with the particular distance to the target; the improvement comprising: 
 a ratio adjustment mechanism in connection between the distance to target indicator/selector and the sight pin that is operable to mechanically vary the ratio of movement between the user adjustment end of the sight holder slide positioning arm and the sight holder slide to mechanically compensate the moving pin archery sight for use with particular arrow speeds generated by particular bow and arrow combinations and/or different arrows with the same bow and/or a distance to target indicator/selector mechanism that allows a user to select a distance to target that corresponds with a predicted distance to a target.    
     
     
         2 . The improved moving pin sight of  claim 1  wherein: 
 the ratio adjustment mechanism comprises: 
 a slide bushing;  
 a slide bushing positioning assembly;  
 a bushing position marker; and  
 a set of arrow speed indicator markings;  
 the slide bushing having a first bushing end slidably entrapped along a slide bushing trackway of the sight holder slide that is oriented at a ninety degree angle to the straight path of travel of the sight holder slide and a second bushing end in connection with the slide bushing positioning assembly;  
 the slide bushing positioning assembly being mounted to the slide connecting end portion of the sight holder slide positioning arm and operable to vary the position of the second bushing end along the slide connecting end portion of the sight holder slide positioning arm and configured to hold the second bushing end at a user set position with respect to the slide connecting end portion of the sight holder slide positioning arm;  
 the bushing position marker being mechanically coupled to the slide bushing in a manner to change position along with the second bushing end in a fixed ratio;  
 the set of arrow speed indicator markings being formed onto a surface adjacent the bushing position marker and parallel to the line of travel of the position marker such that the user may position the bushing position marker adjacent to a particular speed indicator marking to calibrate the ratio of movement between the user adjustment end of the sight holder slide positioning arm and the sight holder slide to the arrow speed at which an arrow shot from an archery bow to which the sight is attached leaves the archery bow;  
 the set of arrow speed indicator markings indicating higher speeds closer to the pivot point;  
 the distance between pairs of individual arrow speed indicator markings becoming incrementally larger as the arrow speed indicated incrementally decreases.
