Archery bow

摘要

An archery bow which requires less force to hold the bow at full draw than to draw the bow through intermediate positions of the draw includes an elongate riser with handle mounted thereon and crank assemblies rotatably mounted at either end thereof. Strut assemblies are pivotally mounted to the crank assemblies and extend outwardly therefrom. A bowstring extends between the outer ends of the strut assemblies. Back lines extends from the outer ends of the strut assemblies to the riser to stabilize and guide movement of the struts as the bowstring is drawn to cause rotation of the crank assemblies or the bowstring is released to allow movement of the bowstring back to its rest or brace position. At least one energy storage limb, and preferably an energy storage limb for each crank assembly, are coupled to the crank assemblies so that rotation of the crank assemblies in response to drawing the bowstring cause deformation of the limbs and energy storage therein, and release of the bowstring from a drawn position results in release of energy from the limbs causing rotation of crank assemblies and movement of the struts to forcibly move the bowstring from drawn to rest or brace position. Timing cables extending between the crank assemblies synchronize rotation of the crank assemblies. The energy storage limb preferably take the form of C-limbs.
