Abstract

An arrow rest assembly for use with a compound bow. The assembly comprises a bracket subassembly mounted to the frame of the bow or to an overdraw assembly, if the bow is optionally equipped therewith; a cable slide slidably mounted on the cable guide bar of the bow and attached to the tuning cables of the bow; a spring loaded arrow rest subassembly rotatable about an axis synchronously with the movement of the tuning cables as the bow string is drawn and released, the subassembly being pivotally mounted to the bracket assembly and carrying an arrow holder guide; and an actuator cord attached to the arrow rest assembly and downwardly acting tuning cable. When the bow is in the relaxed state, the arrow rest subassembly and the actuator cord are in a relaxed position wherein the actuator cord is slack and the arrow rest subassembly acts to keep the arrow from falling off the bow riser of the bow or the shelf of an overdraw assembly, if optionally present. As the bow is drawn, the cable slide moves along the cable guide bar causing the tuning cables to move laterally away from the frame and the actuator cord to lose its slack. Upon becoming taut, the actuator cord overcomes the tension in the spring in the arrow rest subassembly when the bow string is within about 2-4 inches of full draw position, and thereby rotates the holder/guide upward to lift and align the arrow for firing. When the bow string is released from the full draw position, the forward lateral movement of the cable slide and the tuning cables on the cable guide bar, in conjunction with the reverse movement of the formerly downwardly acting tuning cable, allows the cord to go slack. That action permits the spring in the arrow rest subassembly to function, thereby causing the holder/guide of the arrow rest subassembly to rapidly fall away from contact with the arrow.

Claims

1. An arrow rest assembly for use with a compound bow, said bow comprising a frame, optionally equipped with an overdraw assembly, having a cable guide bar extending therefrom, a bow string having an upwardly acting tuning cable and a downwardly acting tuning cable which are attached to a cable slide slidably mounted on said cable guide bar, said assembly comprising:

(a) a bracket subassembly mounted on said bow frame or on said optionally equipped overdraw assembly;

(b) an arrow rest subassembly rotatable about an axis synchronously with the movement of said tuning cables as said bow is drawn and released which contains an internally mounted spring and carries an arrow holder/guide, said subassembly being pivotally mounted to said bracket subassembly; and

(c) an actuator cord prepared from a strong, flexible, but relatively inelastic, material attached to said arrow rest subassembly and said downwardly acting tuning cable which, when said bowstring is drawn in a direction away from said frame to within about 24 inches of full draw position, becomes taut and, overcoming the tension in said spring, rotates said holder/guide of said arrow rest subassembly upward to lift and align an arrow in firing position, and which, when said bowstring is released, becomes slack, thereby allowing said arrow to slide along said holder/guide for about 2-4 inches before allowing the tension in said spring to function causing said holder/guide of said arrow rest subassembly to rapidly fall away from contact with said arrow.

2. An arrow rest assembly according to claim 1 wherein said holder/guide has a truncated, fork-shaped structure comprised of a pair of prongs having end tabs that are bent backwards at an angle.

3. An arrow rest assembly according to claim 2 wherein said end tabs are bent backward at an angle between about 30°

-60°
