Adjustable Bow Sight

Abstract

An adjustable bow sight includes a base, a sight mount, a carrier, and an adjustment mechanism. The base is configured to be mounted to the riser of a bow. The sight mount is configured to facilitate the mounting of a sight to the carrier. The carrier is configured to move with respect to the base but remain fixed with respect to the sight. The adjustment mechanism facilitates the adjustment of the position of the carrier with respect to the base. In a particular embodiment, the carrier moves along an arcuate path when the adjustable bow sight is adjusted. In a more particular embodiment, the sight is a scope.

         4 . The adjustable bow sight of  claim 1 , wherein:
 one of said base and said carrier includes a guide;   the other of said base and said carrier includes a follower configured to mate with said guide; and   said guide and said follower, together, direct said carrier along a path with respect to said base.   
     
     
         5 . The adjustable bow sight of  claim 4 , wherein at least one of said guide and said follower includes a track extending along said path. 
     
     
         6 . The adjustable bow sight of  claim 5 , wherein said path is curved. 
     
     
         7 . The adjustable bow sight of  claim 6 , wherein said path has a radius of curvature that is greater than a largest dimension of said adjustable bow sight. 
     
     
         8 . The adjustable bow sight of  claim 1 , wherein said carrier is selectively movable between a plurality of spaced-apart, discrete positions with respect to said base. 
     
     
         9 . The adjustable bow sight of  claim 8 , wherein:
 one of said carrier and said base includes a detent;   the other of said carrier and said base includes a plurality of valleys positioned and configured to selectively engage said detent; and   each valley of said plurality of valleys corresponds to a respective one of said spaced-apart, discrete positions.   
     
     
         10 . The adjustable bow sight of  claim 1 , wherein said carrier is configured to move along a curved path with respect to said base. 
     
     
         11 . The adjustable bow sight of  claim 10 , wherein said curved path has a radius of curvature corresponding to an average draw length of a number of adult bows. 
     
     
         12 . The adjustable bow sight of  claim 1 , wherein said base includes a plurality of countersunk holes configured to receive a respective plurality of countersunk screws, said plurality of countersunk screws being configured to thread into a respective plurality of threaded holes formed in said riser of said bow. 
     
     
         13 . The adjustable bow sight of  claim 1 , wherein:
 said sight mount includes at least one scope ring mounted to said carrier; and   said sight is a scope.   
     
     
         14 . The adjustable bow sight of  claim 13 , wherein:
 said sight mount includes a first scope ring and a second scope ring; and   said riser of said bow is disposed between said first scope ring, said second scope ring, said base, and said scope when said base is mounted to said bow.   
     
     
         15 . The adjustable bow sight of  claim 1 , wherein:
 said adjustment mechanism includes a shaft, a knob, a pinion gear, and a rack gear;   said shaft extends along a shaft axis;   said shaft is fixed to said base and remains stationary with respect to said base when said carrier is moved along a path with respect to said base; said knob is coupled to said shaft, said knob being rotatable about said shaft axis;   said pinion gear is fixed to said knob;   said rack gear is fixed to said carrier and is configured to mesh with said pinion gear;   said carrier and said rack advance along said path in a forward direction responsive to rotating said pinion gear clockwise about said shaft axis; and   said carrier and said rack advance along said path in a reverse direction responsive to rotating said pinion gear counterclockwise about said shaft axis.   
     
     
         16 . The adjustable bow sight of  claim 15 , further comprising:
 a guide coupled between said base and said carrier, said guide having a first portion and second portion, said first portion of said guide being coupled to said base, and said second portion of said guide being coupled to said carrier; and wherein   said second portion of said guide is configured to slidably engage said first portion of said guide; and   said guide directs said carrier along a path with respect to said base.   
     
     
         17 . The adjustable bow sight of  claim 16 , wherein:
 said first portion of said guide is formed integrally with said base; and   said second portion of said guide is formed integrally with said carrier.   
     
     
         18 . The adjustable bow sight of  claim 16 , further comprising a locking mechanism configured to selectively transition between a locked position and an unlocked position, the position of said pinion gear being fixed with respect to said rack gear when said locking mechanism is in said locked position, and said pinion gear being free to rotate about said shaft axis when said locking mechanism is in said unlocked position. 
     
     
         19 . The adjustable bow sight of  claim 16 , wherein said path is curved. 
     
     
         20 . The adjustable bow sight of  claim 1 , further comprising a locking mechanism, and wherein:
 said locking mechanism including a cam, a pin, and a biasing member;   said pin is seated in a bore in said knob;   said cam includes a handle end that facilitates rotation of said cam by a user;   said cam includes a cam surface that urges against an end of said pin;   said biasing member urges said pin into a retracted position within said bore; and   rotation of said cam urges said pin into an extended position from said bore and into a complementary bore in said base, thereby preventing rotation of said knob with respect to said base.
