US Patent 9149695 Projectile and throwing apparatus and game for projectile throwing

An improved projectile throwing apparatus is described comprising a handle, an elongate shaft, and a throwing head for throwing a projectile, such as a golf ball. The throwing head may be interchangeable with golf shafts of varied lengths, with lacrosse shafts, or other shafts to achieve accurate, long distance golf ball throws. The throwing head may be shaped to achieve throws of different distance, launch angle, and trajectory, optionally imparting spin with a retrograde ramp at the distal end of the throwing head. The throwing apparatus is useful for golf-type game play, including for those with physical disabilities, as well as for a training and instructional aid for golf, lacrosse, and other sports.
