Abstract:
1. A compound bow having an improved vibration damping function, the compound bow comprising: a bow main body, including a handle having two ends, at a central portion of which a grip portion is formed and a pair of limbs that are respectively coupled to both ends of the handle; upper and lower pulley assemblies each including a pulley that is rotatably coupled to a rotating shaft formed on a rear end of each limb, and a cam that is coupled to one side of the pulley and is rotated with the pulley; a bowstring having two ends, whose either end is wound and coupled onto the pulley of each of the upper and lower pulley assemblies; first and second cam cables that are wound around the cam of each of the upper and lower pulley assemblies as the bowstring is pulled, in which one end of each of the first and second cam cables is coupled to one of the upper and lower pulley assemblies, and a second end thereof is coupled to the other of the upper and lower pulley assemblies or the rotating shaft of the other of the upper and lower pulley assemblies; a bowstring support bar whose one end is coupled to the handle and whose other end is coupled to a cushioning member that contacts the bowstring; and a first cam cable anti-vibration bar including a pivot lever whose one end is coupled to the bowstring support bar and whose other end is spaced by a predetermined distance from one end, wherein a throughhole is formed at one end of the pivot lever, into which a front end of the bowstring support bar is inserted; a coupling bar that is coupled to the other end of the pivot lever; and an anti-vibration member that is coupled to a rear end of the coupling bar and whose rear surface contacts one of the first and second cam cables when the bowstring is released to thus return to an original position.
