Abstract
An exercise device comprising a variable speed rotary driving device, an adjustable speed control for the rotary driving device, an exercise link offering resistance to motion of the user, and a hydraulic coupling connecting the variable speed rotary driving device to a torque multiplier. The exercise device operates such that torque is transmitted to the exercise link to impart resistance to motion of the link, and the resistance to motion is variable and also a consistent function of the speed and direction of the link and of the variable speed rotary driving device.
Claims9
An exercise device comprising a variable speed rotary driving means, an adjustable speed control means for controlling the speed of said variable speed rotary driving means, an exercise link offering resistance to motion of a user, a fluid coupling connected to the variable speed rotary driving means through an input shaft, and a torque multiplying means driven by the fluid coupling through an output shaft, said fluid coupling transmitting torque from the input shaft to the output shaft, said torque multiplying means being connected to said exercise link, said fluid coupling imparting resistance to said exercise link, the resistance to motion of said exercise link being a function of the direction of said exercise link and the speed of said variable speed rotary driving means.
