Compound archery bow
摘要:
A compound archery bow includes a bow handle having projection limbs, and first and second pulleys mounted on the limbs for rotation around on axles. A bow cable arrangement includes a bowstring cable extending from a bowstring anchor through a bowstring let-out groove at the first pulley and then toward the second pulley, a first cable extending from a first anchor through a portion of a groove on the first pulley and then toward the second pulley, and a second cable extending from a second anchor through a portion of a groove on the first pulley and then toward the second pulley. The first cable includes a yoke having a first end connected to the first anchor, a split second end connected to the first axle on opposite sides of the first pulley, and a third end extending toward the second pulley. The yoke preferably includes an idler pulley mounted on a bracket. The first cable preferably extends around the idle pulley between the first and second ends, and the third end extends from the bracket toward the second pulley. The second pulley and the bow cable arrangement at the second pulley, including the yoke, preferably are near mirror images of each other at the first and second pulleys.
