Archery Site

Abstract

An archery sight having a pin gap adjustment mechanism to adjust a pin gap between a first pin and a second pin to compensate for arrow drop at different ranges. The pin gap adjustment mechanism may include a cam and a follower pin rigidly connected to the second pin. Input from an actuator may cause the cam to rotate and thereby increase or decrease the pin gap between the first pin and the second pin. The cam may comprise an outer surface with a continuously variable irregular surface to provide multiple adjustments for arrows with different trajectories.

What is claimed is: 
     
         1 . An archery sight for a bow comprising:
 a sight assembly moveably mounted to a vertical gear rack;   the sight assembly having a first pin having a first sight point and a second pin having a second sight point;   a pin gap defined by a distance between the first sight point and the second sight point;   an actuator;   a sight assembly adjustment mechanism configured to move the sight assembly, the first pin, and the second pin up and down along the vertical gear rack responsive to input from the actuator;   a pin gap adjustment mechanism configured to move the second pin with respect to the first pin to thereby vary the pin gap responsive to input from the actuator.   
     
     
         2 . The archery sight of  claim 1 , wherein the actuator is one of a manual actuator and a motorized actuator. 
     
     
         3 . The archery sight of  claim 2 , wherein the manual actuator is one of a hand wheel, knob and lever. 
     
     
         4 . The archery sight of  claim 1 , wherein the sight assembly adjustment mechanism comprises a main driver gear connected to the actuator; wherein the main driver gear is intermeshed with the vertical gear rack. 
     
     
         5 . The archery sight of  claim 1 , wherein the pin gap adjustment mechanism comprises a follower pin in communication with a cam; wherein the second pin is connected to the follower pin; and wherein the cam is rotatable by input from the actuator. 
     
     
         6 . The archery sight of  claim 5 , wherein the cam comprises a curved cam slot; wherein the follower pin is installed into the curved cam slot. 
     
     
         7 . The archery sight of  claim 5 , wherein the cam comprises an outer surface with an irregular profile configured to receive the follower pin. 
     
     
         8 . The archery sight of  claim 7 , wherein the outer surface of the cam comprises a continuously variable irregular profile along an axis of rotation of the cam. 
     
     
         9 . The archery sight of  claim 8 , further comprising a cam adjustment mechanism to adjust a lateral position of the cam with respect to the follower pin. 
     
     
         10 . An archery sight for a bow comprising:
 a sight assembly moveably mounted to a vertical gear rack;   the sight assembly having a first pin having a first sight point and a second pin having a second sight point;   a follower pin connected to the second pin;   a pin gap defined by a distance between the first sight point and the second sight point;   an actuator mounted on a shaft;   a sight assembly adjustment mechanism having a main driver gear in communication with the shaft and intermeshed with the vertical gear rack; and   a pin gap adjustment mechanism having a rotatable cam in communication with the follower pin and the shaft.   
     
     
         11 . The archery sight of  claim 10 , wherein the main driver gear is configured to move the sight assembly, the first pin, and the second pin up and down along the vertical gear rack responsive to rotation of the shaft. 
     
     
         12 . The archery sight of  claim 10 , wherein the rotatable cam is configured to move the second pin with respect to the first pin responsive to rotation of the shaft. 
     
     
         13 . The archery sight of  claim 10 , wherein the rotatable cam comprises a curved cam slot, wherein the follower pin is installed into the curved cam slot. 
     
     
         14 . The archery sight of  claim 10 , wherein the rotating cam comprises an outer surface with an irregular profile configured to receive the follower pin. 
     
     
         15 . The archery sight of  claim 14 , wherein the outer surface comprises a continuously variable irregular profile. 
     
     
         16 . The archery sight of  claim 15 , further comprising a cam adjustment mechanism configured to vary a position of the outer surface along an axis of rotation. 
     
     
         17 . An archery sight for a bow comprising:
 a sight assembly;   the sight assembly having a first pin having a first sight point and a second pin having a second sight point;   a follower pin connected to the second pin;   a pin gap defined by a distance between the first sight point and the second sight point;   an actuator; and   a pin gap adjustment mechanism having a rotatable cam in communication with the follower pin and the actuator.   
     
     
         18 . The archery sight of  claim 17 , wherein the rotatable cam is configured to move the second pin with respect to the first pin responsive to input from the actuator. 
     
     
         19 . The archery sight of  claim 10 , wherein the rotatable cam comprises a curved cam slot, wherein the follower pin is installed into the curved cam slot. 
     
     
         20 . The archery sight of  claim 10 , wherein the rotating cam comprises an outer surface with an irregular profile; wherein the follower pin abuts against the outer surface. 
     
     
         21 . An archery sight for a bow comprising:
 a sight assembly moveably mounted to a vertical gear rack;   the sight assembly having a first pin having a first sight point and a second pin having a second sight point;   an actuator,   a sight assembly adjustment mechanism configured to move the sight assembly along the vertical gear rack responsive to input from the actuator; and   an actuator locking mechanism configured to lock the actuator in place.
