摘要： A bow string drawing and releasing device including a rigid frame within which a pair of jaws are pivotally arranged. An operating rod is rearwardly positioned and is adapted to be rearwardly pulled to pivot the jaws from a normally closed, bow string retaining position to an open, bow string releasing position. A handle grip portion extends rearwardly from the frame and the operating rod extends through the handle grip portion. In one embodiment, the handle grip portion is adapted to rotate relative to the frame. In another embodiment, the handle grip portion is adapted to pivot relative to the frame for triggering purposes.

摘要： A bow trigger mechanism is disclosed which includes a pair of spaced-apart frame members, the frame members defining an operating opening therewithin and terminating rearwardly in an integral handle featuring relatively wide bearing finger pulls. A pair of first and second bent jaws are pivotally retained within the spaced frame members and are movable between a normally closed and locked position to an open position wherein a clearance opening sufficient to allow passage of a bowstring is formed. A non-compressible, non-extendable spring is positioned in linear arrangement between the rearward extensions of the bent jaws and has its respective ends pivotally connected thereto. At least a major portion of the spring is exposed within the operating opening. By pulling rearwardly upon the spring within the clearance opening, the linear arrangement of the spring is transformed into an arcuate configuration, thereby causing the spring ends to move closer together to thus pull the rearward extensions of the jaws toward each other. The inward movement of the jaw extensions creates pivotal movement to open or close the jaw forward ends for bowstring loading, pulling and releasing purposes.

摘要翻译： 公开了一种弓形触发机构，其包括一对间隔开的框架构件，所述框架构件在其中限定操作开口，并且在具有相对较宽的支承手指拉动的整体手柄中向后终止。 一对第一和第二弯曲夹爪枢转地保持在间隔开的框架构件内并且可以在常闭和锁定位置之间移动到打开位置，其中形成足以允许弓弦通过的间隙开口。 不可压缩的不可延伸的弹簧以弯曲夹爪的后延伸部之间的线性布置定位，并且其相应端部枢转地连接到其上。 弹簧的至少大部分暴露在操作开口内。 通过在间隙开口内的弹簧向后拉动，弹簧的线性布置变成弓形构造，从而使弹簧端部更靠近地移动，从而将夹爪的向后延伸部朝向彼此拉动。 钳口延伸部的向内运动产生枢轴运动，以打开或关闭钳口前端用于弓弦加载，拉动和释放目的。
