Abstract:
A draw facilitating bow system comprising, in combination:a compound bow with an intermediate handle portion with a pair of ends each having a threaded post coupled thereto and extending forwardly therefrom, the compound bow further including a pair of resilient limbs each having an inboard end with a bore formed therein for slidably receiving the threaded post and a pair Of pulleys mounted on a side edge of the handle portion and vertically spaced from a center thereof, wherein a portion of each limb adjacent to the inboard end thereof pivots about the associated end of the handle portion of the compound bow;a set member coupled to a center of the handle portion of the bow and extending rearwardly therefrom with a pin extending laterally therefrom;a pair of tension assemblies each including:a first arm having an inboard end coupled to one of the ends of the intermediate handle portion of the bow and extending through an elongated slot formed in one of the limbs and an outboard end coupled to an outboard end of one of the threaded posts of the bow,a second arm having an outboard end hingably coupled to the outboard end of the first arm and the outboard end of one of the threaded posts of the bow,a first pulley rotatably coupled to a post extending laterally from the outboard end of one of the threaded posts of the bow,a roller rotatably mounted to an inboard end of the second arm in rolling abutment with a front surface of one of the limbs of the bow,a pair of threaded rods each having a first end hingably mounted to an end of the roller and extending in parallel relationship with one of the limbs of the bow, wherein second ends of the threaded rods are connected via a post which extends laterally from the bow with a second pulley thereon,a first spring assembly including a coil spring situated about one of the threaded posts between an adjustment nut and one of the limbs of the bow for urging the inboard end of one of the limbs toward the handle portion thereof, anda second spring assembly including a pair of coil springs each situated about one of the threaded rods between an adjustment nut and a stopper mounted on one of the limbs of the bow for urging the roller to move upwardly along one of the limbs of the bow; anda cable wrapped about the pulleys of each of the tension assemblies and further positioned between the pulleys of the bow for being positioned about the pin of the set member for allowing the bow to be more easily drawn.
