    • In an archery bow, variations in the alignment between the limbs and the handle due to manufacturing tolerances or the preferences of an archer are accommodated with a laterally adjustable limb pocket having an elongated feature extending across the pocket. The feature permits at least a portion of the pocket to move from side to side on the handle. The feature is a ridge having a dovetail cross-section for engaging a dovetail slot in the end of the handle. Alternatively, the feature is a hole elongated in a side to side direction across the pocket. The hole receives an internally threaded bushing for locating the pocket while permitting rotation of the pocket about a pivot. For a pair of holes elongated in a side to side direction, the position of the pocket relative to the handle is controlled either by opposed setscrews or by an adjustment screw threaded into the handle.
    • 在射箭弓中,由于制造公差或弓箭手的喜好而在四肢和手柄之间的对准方面的变化由具有延伸穿过口袋的细长特征的横向可调节的侧翼窝容纳。 该特征允许口袋的至少一部分在手柄上从一侧移动到另一侧。 该特征是具有燕尾形横截面的脊,用于接合手柄端部的燕尾槽。 或者,该特征是穿过口袋沿着侧向方向延伸的孔。 该孔容纳用于定位袋的内螺纹衬套,同时允许口袋围绕枢轴转动。 对于在侧向方向上延伸的一对孔,凹口相对于手柄的位置由相对的固定螺丝或螺纹连接到手柄中的调节螺丝控制。

    • A crossbow includes an elongated frame coupled to a riser at a first end thereof. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A movable bowstring release is used both to retract the bowstring into a drawn position, and to release the bowstring under the operation of a trigger assembly. The bowstring release is initially positioned near the bowstring at rest, and a bowstring hook is engaged therewith. A bowstring retractor includes a retractor rope secured to the bowstring release for retracting the bowstring. An upper housing is secured to the second end of the elongated frame, and supports a rope spool used to wind the retractor rope. The bowstring release is retracted into the upper housing proximate a trigger assembly for selectively releasing the bowstring when a user pulls a trigger.
    • 弩包括在其第一端处联接到提升管的细长框架。 提升管支撑一对柔韧的肢体,并且弓弦在这种肢体之间延伸。 使用可移动的弓弦释放装置将弓弦缩回到拉伸位置,并且在触发器组件的操作下释放弓弦。 弓弦释放装置最初位于靠近琴弦的位置,并且弓弦琴与其配合。 弓弦收缩器包括固定到弓弦释放器的收缩绳,用于收缩弓弦。 上壳体固定到细长框架的第二端,并且支撑用于卷绕卷收器绳索的绳卷轴。 弓弦释放件靠近触发器组件缩回到上壳体中,以在用户拉动扳机时选择性地释放弓弦。
