发明名称 COMPOUND BOW
摘要 <p>COMPOUND BOW A compound bow having a handle and flexing limbs extending outwardly from the handle. A bracket is carried adjacent a medial portion of the handle and a pair of arms are pivotally secured thereto. The arms diverge rearwardly from the bracket. A string engaging member is carried adjacent the outer ends of each of the arms. A pair of pulleys are carried adjacent each remote end of the limbs. A bow string has opposed ends thereof attached to a respective inner end of a respective arm. The string extends around the pulleys on the ends of the limbs and the string engaging members so that when a notching portion of the string is drawn for shooting an arrow, the pivotal arms are pivoted from an open extended position to a partially closed position providing a uniform draw of the string when drawing the string from a released position to a fully drawn position. A pair of eccentric cams are carried adjacent the arms over which respective opposed end portions of the string extends. These eccentric cams are pivotally mounted so that when the string is pulled to the fully drawn position, the cams are pivoted, minimizing or steadying the holding force required for holding the string.</p>
