Fiber optic sight pin

Abstract

A sight pin for use with a bow sight includes an elongate segment of fiber optic material used to form a sighting indicia at one of its terminal ends. The other end of the fiber optic member is wound upon a spool to increase the exposed surface area of the fiber optic material to increase light absorption and thus the brightness of the sight indicia.

1 . A sight pin for attachment to a bow sight, comprising: 
 a spool;    a pin arm integrally formed with said spool and depending outwardly therefrom; and    a length of fiber optic material having a first end for forming a sight indicia coupled to said pin arm and at least a portion of said length being wound upon said spool, said spool, said pin arm and said length of fiber optic material forming a sight pin configured for attachment to a bow sight.    
   
   
       2 . The sight pin of  claim 1 , wherein said pin arm and said spool are integrally formed.  
   
   
       3 . The sight pin of  claim 1 , further including a glow-in-the-dark material interposed between said fiber optic material and said spool.  
   
   
       4 . The sight pin of  claim 1 , wherein said pin arm has an arch shape.  
   
   
       5 . The sight pin of  claim 1 , further including an engagement portion integrally formed with said spool configured for engaging with a sight body to prevent rotation of said spool relative to said pin body.  
   
   
       6 . The sight pin of  claim 1 , wherein said spool includes a hollow recess for decreasing the weight of said spool.  
   
   
       7 . The sight pin of  claim 1 , wherein said length of fiber optic material forms a plurality of windings upon said spool.  
   
   
       8 . The sight pin of  claim 7 , further comprising an opaque cap for covering at least a portion of said plurality of windings.  
   
   
       9 . A bow sight, comprising: 
 a sight body comprising a pin plate; and    a plurality of sight pins attached to said pin plate, at least one of said plurality of sight pins comprising a spool, a pin arm depending from said spool, and a length of fiber optic material having a first end for forming a sight indicia coupled to said pin arm and at least a portion of said length being wound upon said spool.    
   
   
       10 . The sight of  claim 9 , wherein said pin arm and said spool are integrally formed.  
   
   
       11 . The sight pin of  claim 10 , further including a glow-in-the-dark material interposed between said fiber optic material and said spool.  
   
   
       12 . The sight of  claim 9 , wherein said pin arm has an arch shape.  
   
   
       13 . The sight of  claim 9 , further including an engagement portion integrally formed with said spool configured for engaging with a sight body to prevent rotation of said spool relative to said pin body.  
   
   
       14 . The sight of  claim 10 , wherein said spool includes a hollow recess for decreasing the weight of said spool.  
   
   
       15 . The sight of  claim 11 , wherein said length of fiber optic material forms a plurality of windings upon said spool.  
   
   
       16 . The sight of  claim 9 , wherein each of said plurality of sight pins includes a spool for winding said length of fiber optic material thereon.  
   
   
       17 . The sight of  claim 9 , wherein said length of fiber optic material of each of said plurality of sight pins is wound upon said spool.  
   
   
       18 . The sight of  claim 9 , wherein said spool is coupled to said sight body.  
   
   
       19 . The sight pin of  claim 15 , further comprising an opaque cap for covering at least a portion of said plurality of windings.  
   
   
       20 . A sight pin, comprising: 
 a spool;    a pin arm depending from and extending away from said spool; and    a length of fiber optic material having a first end for forming a sight indicia coupled to said pin arm and at least a portion of said length being wound upon said spool.    
   
   
       21 . The sight pin of  claim 20 , wherein said pin arm and said spool are integrally formed.  
   
   
       22 . The sight pin of  claim 20 , further including a glow-in-the-dark material interposed between said fiber optic material and said spool.  
   
   
       23 . The sight pin of  claim 20 , wherein said pin arm has an arch shape.  
   
   
       24 . The sight pin of  claim 20 , further including an engagement portion integrally formed with said spool configured for engaging with a sight body to prevent rotation of said spool relative to said pin body.  
   
   
       25 . The sight pin of  claim 20 , wherein said spool includes a hollow recess for decreasing the weight of said spool.  
   
   
       26 . The sight pin of  claim 20 , wherein said length of fiber optic material forms a plurality of windings upon said spool.  
   
   
       27 . The sight pin of  claim 26 , further comprising an opaque cap for covering at least a portion of said plurality of windings.
