摘要： A composite archery bow utilizing a plurality of laminations with fibers oriented to give them a substantial transverse angulation with respect to the long axis of the bow limbs. The fibers in the laminations are oriented in opposite directions on the facing and backing of the limb to prevent any distortion of the finished limb. The recurve portions of the bow are relatively long and straight, and are connected to the major limb portion by a small bend radius portion of approximately two to three inches in radius.

摘要： The primary object of the invention is to increase the use of the stress-accumulating reflex material of the bow by way of making structural changes in the bow bodies manufactured from natural materials, synthetic materials or composite materials formed by a combination of natural and synthetic materials, obtain a bow body that has greater strength as compared to a bow body manufactured according to the conventional methods by way of increasing the contact surface between such material and the frame material, and provide the arrow with speed by way of increasing the potential energy loaded by this bow in the arrow being shot. The subject matter of the invention is a bow (1) embodiment wherein the faces of the frame material (5) and the reflex material (6) that contact/face each other are concave or convex in a way to match one another/fit in the surface of one another in at least one of the bow body (2) and the bow members (3) that are formed by at least one of and often by a combination of the flexibility material (4), frame (5) and reflex material (6).

摘要： 본 고안은 자연소재를 이용하여 자연 친화적일뿐 아니라 자연적으로 형성된 대나무 마디를 활대중앙에 위치시킴으로 강성이 보강된 활대에 관한 것이다.
즉 본 고안은 대나무를 절개하여 형성되는 활대에 있어서, 상기 대나무 마디가 활대의 중앙에 위치하도록 구성된다. 또한, 본 고안은 상기 활대에는 절개된 대나무가 각각 내면이 대향하도록 적층하되, 중앙에는 대나무 마디가 겹치도록 구성될 수 있다.
