Archery bow with cable splitter

Abstract

A bow (e.g., compound bow, cross bow, etc.) that includes a cable splitter. The cable splitter is easy to install in that it does not require access to the yoke ends of the bow string. The cable splitter is self-anchoring to the cable. In addition, the cable splitter eliminates the need for a separate saddle and separate section of cable. The cable splitter also allows for tuning for cam lean by adding or removing twist in the yoke ends.

Description

BACKGROUND

Modern archery typically involves the shooting of bows that include cam systems that enable the bow string to be held back at full draw with less force than is required to pull back the bow string. This feature known as “let off” is a desirable feature for hunting and general shooting as it enables the shooter to maintain full draw for a relatively long period of time. The cam systems typically include one or more cables that are connected between cams and/or idler wheels supported at the opposite end of the limbs of the bow. To provide an unobstructed path for the arrow flight from the bow, a cable guard is often used to bias the cables out of the bow string plane. A side effect of this cable guard, as well as the varying forces and leverages that the bow string and cables impart on the cams as they rotate, can result in twisting forces and deflection of the cams commonly referred to as “cam lean.” Excessive cam lean is undesirable. One way to minimize cam lean is to configure the bow such that the cables apply a generally balanced force on the cam. In some systems, the cable terminates at a saddle component that is generally centered over the cam and a separate cable connects the saddle to opposed sides of the cam.

SUMMARY

The present disclosure provides a bow (e.g., compound bow, cross bow, etc.) that includes a cable splitter. The cable splitter of the depicted embodiment is easy to install in that it does not require access to the yoke ends of the bow string. The cable splitter of the depicted embodiment is self-anchoring to the cable. In addition, the cable splitter of the preferred embodiment eliminates the need for a separate saddle and separate section of cable. The cable splitter of the present disclosure also allows for tuning for cam lean by adding or removing twist in the yoke ends.
