摘要： An archery training aid is provided including a body and a finger rest extending outward at an angle from a base. The finger rest can include a finger rest surface configured to engage one or more fingers of a hand. The base can be configured to be placed in engagement with a first lateral grip surface of a bow grip so that the finger rest surface is disposed at a first angle between 25° to 65°, inclusive, or between 30° and 50°, inclusive, relative to the first lateral grip surface. A related method of use is provided to impair or prevent bow torque imparted by an archer's hand on a bow.

摘要： A mechanical broadhead, which has blades movable from a retracted mode to a deployed mode, is provided with ball and socket members that hold the blades in the retracted mode, and selectively release the blades to the deployed mode. The ball and socket members, which can be on the blades and/or on a retainer element, can be snapped together to provide an audible snap confirming locking of the blades in the retracted mode. The mechanical broadhead can include first and second ferrule portions removably joined with one another. The second ferrule portion can acquire a blocking mode to block a removal opening of a ferrule slot defined in the first ferrule portion so that blade cannot be removed from respective ferrule slots. The second ferrule portion can achieve a removal mode so that the blades can be removed from the slots.

摘要： An archery bow is provided having a cam assembly including a first bowstring track and a second bowstring track laterally separated by a distance, and adapted to guide different portions of a bowstring. The bowstring tracks can be spaced from one another along an axis of rotation of the cam assembly so that the loads exerted by the bowstring portions are substantially balanced. Accordingly, the loads are inhibited from urging the cam to lean out of vertical alignment and/or twisting the limb. The cam assembly can include a power cable track which guides a cable centered on the axis of rotation, and which is within a central longitudinal limb plane. Large, dynamic loads exerted by the power cable through the cam assembly can be centered to inhibit cam lean and limb torque. A related method of inhibiting limb twist, and a split bowstring also are provided.
摘要翻译：提供了一种具有凸轮组件的凸轮组件，凸轮组件包括横向分开一定距离的第一弓弦轨道和第二弓弦轨道，并且适于引导弓弦的不同部分。弓弦轨道可以沿着凸轮组件的旋转轴线彼此间隔开，使得由弓弦部分施加的载荷基本平衡。因此，禁止负载促使凸轮倾斜并垂直对准和/或扭转肢体。凸轮组件可以包括引导以旋转轴线为中心并且在中心纵向肢体平面内的电缆的电力电缆轨道。电动电缆通过凸轮组件施加的大的动态载荷可以对中以抑制凸轮偏心和肢体扭矩。还提供了一种抑制肢体扭曲的方法，还提供了分割弓弦。

摘要： An archery bow is provided including a cable guard and/or cable guide that can flex to selectively move a cable relative to a plane in which a bowstring of the bow travels to minimize cam lean, limb twist, and/or cable wear. The cable guard and/or guide can move toward the bowstring plane as the bowstring is drawn, and away from the bowstring plane, out of the way of the bowstring and any attached arrow, after the bowstring is released. The cable guard can define a bore, for example, an elongated bore, extending through it along an axis that is generally parallel to the bowstring when the bowstring is undrawn. The cable guard bore can operate as a cable guide, and can include a rounded opening to minimize abrasion to a cable moving through it. A ceramic element can be included in the bore to minimize abrasion to the cable.
摘要翻译：提供了一种射箭弓，其包括电缆护套和/或电缆引导件，其可以弯曲以选择性地相对于弓的弓弦行进的平面移动电缆，以最小化凸轮偏心，肢体扭曲和/或电缆磨损。在弓弦被释放之后，电缆护套和/或引导件可以沿着弓弦被拉动并远离弓弦平面移动到弓弦平面，从弓弦和任何附加箭头的方式移开。电缆护套可以限定一个孔，例如一个细长的孔，当弓弦未被拉伸时，其沿着大致平行于弓弦的轴线延伸穿过该孔。电缆保护孔可以作为电缆引导件操作，并且可以包括圆形开口，以最小化对通过它的电缆的磨损。孔中可以包含一个陶瓷元件，以最大程度减少对电缆的磨损。
