发明名称 Archery device with constrained four-bar linkage
摘要 An archery device in which flexible limbs are supported on a limb holder by means of pairs of pivoted swing arms, the limbs, holder member and swing arm pairs each forming a four bar linkage system allowing the limbs to swing rearwards upon drawing of a connected drawstring. Load cables are connected to each limb tip which constrain the limb movement to cause flexing of the limbs during the draw. The load cables move towards alignment with the swing arms to reduce draw effort at full draw.
