Optical/visual triangulation for sighting archery bows

Abstract

A sighting assembly for archery bows which utilizes optical and visual triangulation is disclosed. A directionalized beam of light from a light source assembly is impinged upon the center of a remote target from an archery bow or an arrow along the axis of the arrow while the archer aligns the peep sight of a drawn bow string and the pin sight so that the resulting line of view of the archer intersects the beam of light at the center of the target. Thus, the bow is sighted without launching an arrow.

1 . A method of visually and optically sighting an archery bow without shooting an arrow: comprising the acts of:
 directing a beam of light onto a center of a spaced target from a distal end of the arrow supported by the bow in a ready-to-shoot position;   visually aligning (a) a draw string peep sight when a string of the bow is retracted, (b) an adjustable pin sight carried by the handle of the bow, and (c) the center of the target.   
   
   
       2 . A method according to  claim 1  wherein the directing act comprises lineally directing the beam of light coaxially with a centerline of the arrow so that the beam impinges on the center of the target. 
   
   
       3 . A method according to  claim 1  wherein the beam comprises laser light obtained from a light emitting diode disposed at the distal end of the arrow. 
   
   
       4 . A method according to  claim 1  wherein the directing act follows the act of temporarily but securely attaching a light source to the distal end of an arrowheadless arrow. 
   
   
       5 . A method of visually and optically sighting an archery bow comprising the acts of:
 directing light along a path between an arrow rest and a knock point of the archery bow so as to impinge upon a selected point of a remote target;   adjusting the line of sight between a peep sight attach to a fully drawn string of the bow and an adjustable pin sight carried on a handle of the bow so that the line of sight intersects the selected point of the remote target.   
   
   
       6 . In combination:
 an arrow;   a source of light removably but securely mounted at a distal end of the arrow for beaming the light onto a remote target to assist in sighting an archery bow without launching an arrow.   
   
   
       7 . In combination:
 an archery bow;   a source of light carried by the bow adjacent to an arrow rest of the bow for beaming the light onto a remote target to assist in sighting the bow without launching an arrow.   
   
   
       8 . A light source assembly for assisting in sighting an archery bow without launching an arrow comprising:
 a housing;   an aperture in the housing for lineally beaming light toward a target;   a source of light disposed within the housing;   a low voltage source of electrical energy disposed within the housing in electrical communication with the light source;   a connector for mounting the assembly to the arrow or the bow.
