    • Foot treadle operated exercising apparatus of this invention provides for transfer of air from one foot treadle operated vertically disposed bellows to another through a restricted pathway adjustable in size by an adjustable valve to select a desired work load. A stroke length adjustment is featured for changing the length of the stroke. This is achieved with bellows that are biassed to return to an extended condition in the presence of atmospheric air. Thus with a closed air system, a manually operated air admission and venting valve will increase the bellows height when opened to admit atmospheric air and will decrease the bellows height when opened and pedals are depressed to vent air. The foot treadles are operable from a standing, sitting or lying position. An auxiliary arm exercise harness operates in conjunction with the foot operated treadles by means of hand manipulated lines cross connected so that the left hand will depress a right foot treadle and visa versa. The entire work load is effected by the transfer of air from one bellows to the other when the treadles are operated in a riding, jogging or climbing action. One embodiment provides for bicycle riding type of exercise activity.
    • 本发明的脚踏踏板操作的锻炼装置提供了从一个脚踏踏板将空气从垂直设置的波纹管传送到另一个脚踏板,通过可调节的阀门可调整大小的限制路径,以选择所需的工作负荷。 行程长度调整用于改变行程的长度。 这是通过在大气存在的情况下被偏压以返回到扩展状态的波纹管来实现的。 因此,使用封闭的空气系统,手动进气和排气阀将在打开时增加波纹管高度,以允许大气空气,并​​且在打开时降低波纹管高度,并且踏板被压下以排出空气。 脚踏踏板可从站立,坐姿或卧位操作。 辅助手臂运动装置通过手动操纵线与脚踏操作的踏板一起操作,这些手动操纵线交叉连接,使得左手将压下右脚踏板,反之亦然。 当踏板在骑马,慢跑或攀爬动作中操作时,整个作业负载通过将空气从一个波纹管传递到另一个来实现。 一个实施例提供了骑自行车骑行类型的运动活动。
