ABSTRACT:
An archery device is disclosed utilizing separate bending and lauching bowstrings strung on a bow member, the launching bowstring closely positioned to the bow member in the undrawn condition to enable front end launching of an arrow engaged at its forward end by a split configuration of the launching bowstring, the arrow passing between bifurcated portions of the bow member when fired. The bending bowstring when drawn operates a system of rotary drive elements to cause highly leveraged flexing of pivoted limbs mounted at either end. The tips of the flexed limbs are fixed to the launching bowstring, and at firing, the bending drive system allows the flexed limbs to release their stored energy into the lauching bowstring to accelerate the arrow. The separate bending-launching bowstring system enables relatively great arrow accelerating forces to be developed, which are easily withstood by the arrow, since the forces are applied to the front end of the arrow. A special limp bodied or arrow or a rigid bodied arrow with a sliding head are used with the device.
