    • The present invention provides for in one embodiment an archery exerciser training device designed to eliminate or minimize target panic, develop muscle memory, and warn up muscles before using a bow and arrow. The training device consists of a cylindrical tube with an attached handle. Within the tube is a gas compression spring with integrated plungers mounted on either end. Each plunger further includes an axle on which two wheels are opposingly mounted. A cable is mounted to one plunger at the distal end of the device and the cable travels in a zig-zag fashion around the four wheels and out of the plunger at the proximal end of the device and terminates in a loop, thereby creating a pulley system. The exposed loop of the cable is pulled in a rearward direction, approximating the motions made when drawing a bowstring. When the exposed loop is pulled, the distal plunger is forced rearward, thereby compressing the gas spring and creating an opposing force approximately equal to a typical draw weight of a bowstring. When the cable is released, the gas spring extends, pushing the distal plunger forward, and pulling the exposed cable back within the cylindrical tube in a safe and controlled manner. The process may be repeated over and over as necessary to sufficiently develop and train the archer's shooting muscles, and to warm up the muscles prior to shooting.
    • 本发明在一个实施例中提供了一种设计用于消除或最小化目标恐慌,发展肌肉记忆以及在使用弓箭之前预热肌肉的射箭练习器训练装置。 训练装置由具有连接手柄的圆柱形管组成。 管内有一个气体压缩弹簧,两端装有集成的柱塞。 每个柱塞还包括一个轴,两个车轮相对安装在该车轴上。 电缆在装置的远端安装到一个柱塞,并且电缆以锯齿形的方式围绕四个轮行进并且在装置的近端处离开柱塞,并且终止于环,从而形成滑轮 系统。 电缆的裸露环路向后拉动,近似于绘制弓弦时所做的运动。 当暴露的环被拉动时,远端柱塞被迫向后,从而压缩气体弹簧并产生大致等于弓弦的典型拉力的相反力。 当电缆被释放时,气体弹簧延伸,向前推动远端柱塞,并以安全和受控的方式将暴露的电缆拉回到圆柱形管内。 可以根据需要一遍又一遍地重复该过程,以充分发展和训练射手的射击肌肉,并在射击之前预热肌肉。
