    • A walking/jogging exercise machine includes a machine frame supported upon a generally horizontally extending floor. A shaft is mounted for rotation on the machine frame, and a pair of cams is mounted for rotation on the shaft. A pair of movable track assemblies has rear portions with rear ends pivotally connected to the machine frame, and front portions with movable front ends. A pair of articulated cam follower assemblies extend between the machine frame and the front ends of the track assembly front portions. The cam follower assemblies include cam rollers operably engaged upon peripheries of the cams, and the cam follower assemblies move in response to rotation of the cams. A pair of foot assemblies is mounted for sliding movement on the track assemblies. A linkage arrangement between the cams and the foot assemblies is provided for transferring movement of the foot assemblies to the cams such that the articulated cam follower assemblies enable a leveraged range of up and down movement of the track assemblies to product an increase in bending of a user's knees resulting in a enhanced natural stepping motion.
    • 步行/慢跑运动机包括支撑在大致水平延伸的地板上的机架。 安装轴用于在机架上旋转,并且一对凸轮安装成用于在轴上旋转。 一对可动轨道组件具有后部,其后端枢转地连接到机架,前部具有可动前端。 一对铰接的凸轮从动件组件在机架和轨道组件前部的前端之间延伸。 凸轮从动件组件包括可操作地接合在凸轮的周边的凸轮滚子,并且凸轮从动件组件响应于凸轮的旋转而移动。 安装一对脚组件以在轨道组件上滑动。 提供凸轮和脚组件之间的连接装置,用于将脚组件的运动传递到凸轮,使得铰接的凸轮从动件组件能够实现轨道组件的上下运动的范围,以产生一个 使用者的膝盖产生增强的自然步进运动。
