Compound bow cam arrangement with balancing yoke

Abstract

In certain arrangements, a balancing yoke is used in a hybrid cam arrangement of an archery bow, in which two cables are paid out from respective tracks or taken up in respective tracks on a cam when the bow is drawn. Aspects of the present disclosure incorporate a balancing yoke which has two leg portions which are symmetrically paid out or taken up in tracks on opposite sides of the cam's central rotational plane and wherein the force applied by a cable is divided and applied by the yoke legs to the cam on opposite sides of the cam's central rotational plane.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to provisional application Ser. No. 62 / 106,428 filed on Jan. 22, 2015, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates generally to archery bows and more particularly pertains to a cam and cable arrangement with balancing yokes for use with and mounted to archery bows.BACKGROUND OF THE INVENTION[0003]An archery bow stores energy when an archer draws the bowstring. When the bowstring is released, the stored energy propels the arrow. A bow typically has a central riser portion, with upper and lower limbs extending to limb tips. In compound bow arrangements, rotatable elements, often called wheels or cams, are respectively mounted at the upper and lower limb tips. The cable arrangements of the compound bows are arranged between the opposing limb tips and the cams.[0004]The cable arrangements store energy from the bent limbs in an undrawn position and store f...

AI Technical Summary

Benefits of technology

The patent describes archery bows that have a unique cam arrangement with a lower balancing yoke. This arrangement allows for more effective and accurate bowstring feeding and faster shots. The balancing yoke helps to evenly distribute the force applied by the cam when the bow is drawn, ensuring consistent and reliable performance. The technical effects of this design include improved performance, efficiency, and reliability, making these bows better suited for hunting and other archery activities.

Problems solved by technology

Any cable force or the net force from a combination of cables applied to a cam which is offset from the ideal central rotational plane of the cam can result in a twisting or torqueing force applied to the cam.

This may cause the cam to undesirably lean to one side and / or to change in the amount and / or direction of lean as the cam rotates during use of the bow.

Undesired lean of the cam can make accurate use of the bow more difficult and can contribute to wear and tear on the bow and components.
