Roller cable guard

Abstract

In certain embodiments, an archery bow comprises an archery bow body defining opposing limb tips having rotational elements and a bowstring extending between the limb tips. At least one cable portion extends between the limb tips. A cable guard extends from the archery body bow body and a pair of pulleys are rotationally mounted to the cable guard wherein the pair of pulleys retain the at least one cable between them and are vertically offset from each other.

1 . An archery bow, comprising:
 an archery bow body defining opposing limb tips;   a bowstring extending between said limb tips;   at least one cable portion extending between said limb tips;   a cable guard extending from said archery body bow body;   a pair of pulleys rotationally mounted to said cable guard, wherein said pair of pulleys in combination encircle at least 360 degrees of the circumference of said at least one cable.   
     
     
         2 . The archery bow of  claim 1 , wherein said pulleys each encircle at least 180 degrees of the circumference of said at least one cable portion. 
     
     
         3 . The archery bow of  claim 1 , wherein said pulleys engage said at least one cable at a pair of positions vertically offset from each other along the length of said at least one cable portion. 
     
     
         4 . The archery bow of  claim 1 , wherein said pulleys each define a groove having an inner groove radius and a pair of sidewalls, wherein said at least one cable portion concurrently contacts the inner groove radius of each of said pulleys. 
     
     
         5 . The archery bow of  claim 1 , comprising two cable portions extending between said limb tips and two pairs of pulleys rotationally mounted to said cable guard, wherein each of said cable portions is engaged by two pulleys which in combination encircle at least 360 degrees of the circumference of said cable portions. 
     
     
         6 . The archery bow of  claim 1 , comprising two cable portions extending between said limb tips and two pairs of pulleys rotationally mounted to said cable guard, wherein two of said pulleys are mounted to said cable guard at positions which offset horizontally and vertically relative to the other two of said pulleys. 
     
     
         7 . The archery bow of  claim 1 , comprising two cable portions extending between said limb tips and two pairs of pulleys rotationally mounted to said cable guard, wherein each of said cable portions defines a brace angle measured in the brace position between the portions extending towards the opposing limb tips from a cable bend point where the cable portion engages a forwardly placed pulley, and said cable portions each define a drawn angle measured between the portions extending towards the respective limb tips from the cable bend point in the drawn position, and wherein the drawn angle is larger than the brace angle. 
     
     
         8 . An archery bow, comprising:
 an archery bow body defining opposing limb tips having rotational elements;   a bowstring extending between said limb tips;   at least one cable portion extending between said limb tips;   a cable guard extending from said archery body bow body;   a pair of pulleys rotationally mounted to said cable guard, wherein said pair of pulleys retain said at least one cable between them and are vertically offset from each other.   
     
     
         9 . The archery bow of  claim 8 , wherein said bow defines a brace position and a drawn position, wherein said at least one cable portion applies force to one of said pair of pulleys in said brace position and wherein movement of the limb tips and rotation of said rotational elements causes the cable portion to transfer the majority of the force to the other of said pair of pulleys as said bow is moved to said drawn position. 
     
     
         10 . The archery bow of  claim 8 , comprising two cable portions extending between said limb tips and two pairs of pulleys rotationally mounted to said cable guard, wherein each pair of pulleys retain said at least one cable portion between them and wherein one pulley of each pair of pulleys is vertically offset from the other. 
     
     
         11 . An archery bow, comprising:
 an archery bow body defining opposing limb tips;   a bowstring extending between said limb tips;   at least one cable portion extending between said limb tips;   a cable guard extending from said archery body bow body;   a pair of pulleys rotationally mounted to said cable guard and retaining said at least one cable between them, wherein each pulley defines an outer radius, and wherein said pair of pulleys are mounted horizontally offset from each other by a distance less than the sum of their respective outer radii.   
     
     
         12 . The archery bow of  claim 11 , wherein said pair of pulleys each define a groove having an inner groove radius and a pair of sidewalls, wherein said at least one cable portion concurrently contacts the inner groove radius of each of said pulleys. 
     
     
         13 . A cable guard for an archery body, comprising:
 a. a cable guard arm having a forward end mountable to the riser of an archery bow and an opposing rearward end;   b. a pair of forward pulleys mounted along the length of said cable guard arm;   c. a pair of rearward pulleys spatially separated from said pair of forward pulleys, wherein said rearward pulleys are mounted to said cable guard arm rearward of said forward pulleys and vertically offset from said forward pulleys.   
     
     
         14 . The cable guard of  claim 13 , wherein said rearward pulleys are mounted to said cable guard arm vertically offset upward from said forward pulleys. 
     
     
         15 . The cable guard of  claim 13 , wherein said rearward pulleys are mounted to said cable guard arm vertically offset downward from said forward pulleys. 
     
     
         16 . The cable guard of  claim 13 , wherein said forward pair of pulleys define an outer radius, wherein said rearward pair of pulleys define an outer radius and wherein said pair of rearward pulleys are mounted rearward of said forward pulley by a distance less than the sum of their outer radii. 
     
     
         17 . The cable guard of  claim 13 , wherein said cable guard arm defines a bend area between the forward end and the rearward end. 
     
     
         18 . The cable guard of  claim 17 , wherein said bend area has an “S” profile. 
     
     
         19 . The cable guard of  claim 18 , wherein said rearward end is bent towards the plane in which the bowstring travels when drawn and released, placing said rearward pair of pulleys closer to the plane than said forward pair of pulleys.
