    • A rowing apparatus having an elongate frame, a seat mounted for slidable displacement along that frame and a handle/cable arrangement fixedly mounted to an axle journaled in the frame. The cable being wrapped about a reel mounted on that axle causes a rotation of that axle in a first direction upon a given displacement. The axle is likewise fitted with a spring which is tensioned upon the axle's rotation in a first direction. Upon the storage of sufficeint energy in that spring, the spring effects a counter rotation of the axle to return the cable and its associated handle to its rest position. The axle is fitted with a flywheel, and a means adapted for applying a frictional drag force thereto. The drag means is adapted for controlling the resistance of the handle to displacement outwardly from the frame and further, for controlling the force by which the handle is urged restoringly back to its rest position.
    • 具有细长框架的划船装置,安装成用于沿该框架可滑动移位的座椅和固定地安装到在框架中轴颈的轴的手柄/电缆装置。 围绕安装在该轴上的卷轴缠绕的电缆在给定位移时使得该轴在第一方向上的旋转。 轴同样装有弹簧,该弹簧在轴沿第一方向旋转时被张紧。 在弹簧中存储足够的能量时,弹簧会影响轴的反向旋转,以将电缆及其相关的手柄返回到其静止位置。 轴配有飞轮和适于向其施加摩擦阻力的装置。 牵引装置适于控制手柄从框架向外移动的阻力,并且还用于控制把手被推回的力恢复到其静止位置。
