Compound bow has rigid sections linked by spring loaded joints incorporating bow string reels and with a position adjustable arrow slot

摘要

A compound bow with ease of use and with an easier pulling force has two rigid convex outer sections joined to a rigid middle grip section by swivel joints incorporating spring loaded reels for the ends of the bowstring. The bowstring is looped over pulleys at the free ends of the outer arms and taken to the pulleys. The power of the bow is set by the diameter of the pulley reels and the strength of the spiral springs. The arrow is laid through a slot plate with adjustable fitting in the centre of the centre section, and is held by a ring magnet fitted to the slot and a ferromagnetic section of the arrow.
