Archery bow sight

Abstract

The invention encompasses archery bow sights that comprise at least one lens configured to eliminate parallax. In one aspect of the invention, the site includes at least one plus power ribbon accommodating lens supported by a support means. A reference means is forwardly mounted in front of the lens so as to be located along the archer's line of sight between the lens and a target when the archer is shooting the bow. The optical lens of the sight eliminates parallax so that the archer's eye does not need to realign his line of sight between an archery peep, the reference means, and the target when the archer changes elevation of the bow.

What is claimed is: 
     
         1 . An archery bow sight comprising:
 A at least one optical element;   A support element configured to support said optical element; and   A at least one reference means for referencing a specific distance of the target from the bow, said reference means being forwardly positioned from said optical element at a distance about equal to one focal length from said optical element, forwardly being defined as the direction in which an archer would shoot an arrow.   
     
     
         2 . The archery bow sight of  claim 1 , wherein said reference means comprises a at least one pin. 
     
     
         3 . The archery bow sight of  claim 1 , wherein said reference point comprises a at least one conical pointer whereby said conical pointer reflects indirect light hitting said conical pointer at all angles allowing for a definitive aiming point. 
     
     
         4 . The archery bow sight of  claim 1 , wherein said optical element comprises a single focal length optical lens having a focal length about equal to a distance between said lens and said reference means. 
     
     
         5 . The archery bow sight of  claim 4 , wherein said optical lens comprises a at least one plus power ribbon accommodating optical lens. 
     
     
         6 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens comprises a spherical lens, said spherical lens including, but not limited to, a biconvex lens or a meniscus lens. 
     
     
         7 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens is configured substantially horizontal to the axis of the archery bow. 
     
     
         8 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens is configured substantially vertical to the axis of the archery bow. 
     
     
         9 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens is configured as about a half lens, whereby said half lens covers and magnifies about half of the area of said sight and whereby about half of the area of said sight is open to the archer's natural line of sight. 
     
     
         10 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens is configured as about a half ribbon lens, whereby said half ribbon lens covers a portion of said sight but does not extend completely across said sight. 
     
     
         11 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens further comprises an antireflective coating whereby the critical angle of the light passing through said antireflective coating is increased. 
     
     
         12 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens comprises a dioptric power of from plus 0.50 dioptric power to plus 16 dioptric power. 
     
     
         13 . The archery bow sight of  claim 5 , wherein said plus power ribbon accommodating lens comprises an achromatic lens. 
     
     
         14 . The archery bow sight of  claim 13 , wherein said plus power ribbon accommodating lens further comprises an achromatic doublet configured with two individual lenses. 
     
     
         15 . The archery bow sight of  claim 14 , wherein said achromatic doublet further comprises a concave lens and a convex lens. 
     
     
         16 . The archery bow sight of  claim 14 , wherein said achromatic doublet further comprises a plano convex lens. 
     
     
         17 . An archery bow sight comprising:
 A plus power optical lens having a single focal length;   A support element configured to support said plus power optical lens; and   A at least one reference means forwardly positioned from said plus power optical lens a distance about equal to the distance between said lens and said focal point, forwardly being defined as the direction in which an archer would shoot an arrow.   
     
     
         18 . The archery bow sight of  claim 17 , wherein said plus power optical lens is a spherical lens, including, but not limited to, a biconvex lens or a meniscus lens. 
     
     
         19 . The archery bow sight of  claim 17 , further comprising a frame configured to accommodate said optical element, said support means for said optical element, and said reference means, said frame configured for mounting on an archery bow. 
     
     
         20 . A method of removing the effect of parallax from an archery bow sight comprising the acts of:
 Viewing a reference pin through a plus power ribbon accommodating optical lens wherein said reference pin is located about a single focal length from said optical lens;   Aligning said reference pin as viewed through said plus power ribbon accommodating optical lens with a target; and   Aiming the archery bow at said target.
