  • Patent number: 5630405
    Abstract: A shooting bow is employed for shooting in sporting events and for shooting game. The shooting bow includes a main part, arms, convex in the direction of shooting, and pulleys, fastened to free tips of the arms. A bowstring passes via the pulleys, and a frame mounts the main part and a trigger mechanism. On the frame there are fastened a guide of a carriage, made up with a track, a groove for the bowstring and cutouts. The number of cutouts corresponds to the number of fletchings of an arrow. The arms are made so that the total impulse of the "arms-pulleys" and "arrow-carriage" systems, at each instant of arms straightening, approaches zero.
