摘要： An archery bow has a pair of limbs with at least one of the limbs having a split section defining a pair of limb sections generally separate from each other. A connecting member is received within the split section to connect the limb sections to each other between a point of string attachment and a handle portion of the bow. The connecting member limits relative movement between the limb sections.

摘要： An archery bow has a cable guard with at least one guide pulley rotatably carried by the cable guard to receive at least one harness string portion and maintain the harness string portion out of a user's way while using the bow. The archery bow has a body or riser with a handle portion and a pair of limbs each having a free end spaced from the handle portion. A separate pulley is rotatably carried adjacent the free ends of each limb and at least one string is trained around the pulleys and has a draw string portion and at least one harness string portion. The harness string portion is trained around at least a portion of a guide pulley, and if more than one harness string portion is provided, then each harness string portion may be trained around a separate guide pulley to maintain the harness string portions separate from each other and to maintain each harness string portion in a laterally spaced relation from the drawstring portion.

摘要翻译： 射箭弓具有电缆防护装置，其中至少一个引导滑轮由电缆护罩可转动地承载，以接收至少一个线束线部分，并且在使用弓弓时将线束弦部分保持在使用者的方式之外。 射箭弓具有带手柄部分和一对肢体的主体或立管，每个肢体具有与把手部分间隔开的自由端。 单独的皮带轮可旋转地携带在每个肢体的自由端附近，并且围绕皮带轮训练至少一个琴弦，并具有拉弦部分和至少一个线束弦部分。 线束串部分围绕导向滑轮的至少一部分被训练，并且如果设置了多于一个线束串部分，则可以围绕单独的导向滑轮来训练每个线束线部分，以将线束线部分彼此分离 并且将每个线束串部分保持为与束带部分横向间隔开的关系。

摘要： An archery bow has at least one dampener to reduce noise and vibration of the bow in use. Desirably, at least one dampener, and preferably a plurality of individual dampeners may be disposed in the area of the connection of a limb to a riser or handle portion of the bow to reduce vibrations transferred to the riser by the limb. Additionally, the archery bow preferably has a cam adapted to receive a dampener to reduce the noise and vibration passing between the cam and the limb. Any number of dampeners may be used in combination, or the dampeners may be used separately as desired.

摘要： A compound bow having a pair of cam modules or secondary cams with at least one cam module having a draw stop integral therewith to engage a harness string of the compound bow at the optimum draw length of the bowstring to prevent this optimum draw length from being exceeded and to efficiently and repeatably store the same quantity of energy in the compound bow. The integral draw stop decreases vibration of the bow in use and cannot be moved to thereby insure that the optimum draw length can be readily achieved throughout the life of the bow. A floor or post is also preferably provided on each cam module to firmly hold and retain one end of a harness string. A track formed in the cam module, which increasingly receives the harness string as a bowstring is drawn, preferably has an inside surface adjacent to a primary cam substantially perpendicular to its axis of rotation and an inclined outside surface spaced from the primary cam providing a track having a width at its outer edge greater than the diameter or width of the harness string to more smoothly receive the harness string within the track to reduce friction between them and thereby reduce string wear and provide an extremely smooth draw of the bowstring.

摘要翻译： 具有一对凸轮模块或副凸轮的复合弓具有至少一个凸轮模块，该凸轮模块具有与其成一体的牵引止动件，以与弓弦的最佳拉伸长度接合复合弓的线束，以防止该最佳拉伸长度被超过 并且有效地并可重复地将相同数量的能量存储在复合弓中。 整体拉伸止动件减少了使用中的弓的振动，并且不能移动，从而确保在弓的整个寿命期间可以容易地实现最佳的拉伸长度。 还优选地，在每个凸轮模块上设置地板或柱，以牢固地保持和保持线束串的一端。 在凸轮模块中形成的轨道越来越多地接收作为弓弦的线束串，其优选地具有与基本上垂直于其旋转轴线的主凸轮相邻的内表面，以及与主凸轮间隔开的倾斜外表面，其提供轨道 在其外边缘处的宽度大于线束串的直径或宽度，以更平稳地将线束串接收在轨道内，以减少它们之间的摩擦，从而减少线的磨损并提供极其平滑的弓弦拉伸。
