Abstract
A bow includes a centrally arranged handle and a bow limb emanating from each end of the handle, with a cord being tensioned between the outer ends of the bow limbs. The inner ends of the bow limbs are shaped into forks whose tines (which act as springs) are fastened separately, each to a frontal face of the handle. The special configuration increases the energy stored in the bow and reduces the force required for tensioning the cord.
