Abstract

An exercise apparatus comprises a variable speed rotary driving device which generates a torque having a magnitude dependent on its speed of rotation; an adjustable speed control which controls the speed of rotation of the rotary driving device; an exercise element, mainpulable by a user; and a torque transmission which transmits torque from the rotary driving device to the exercise element so as to resist manipulation of the exercise element and to allow for lost motion between the rotary driving device and the exercise element. The torque transmission transmits torque, from the rotary driving device to the exercise element, of a magnitude substantially independently of the motion of the exercise element and dependent upon the speed of rotation of the rotary driving device.

Claims23

Dependent claims

An exercise apparatus comprising:

a rotary driving means for generating a torque, said rotary driving means having a variable speed of rotation;
an adjustable speed control means, operably connected to said rotary driving means, for varying the speed of rotation of said rotary driving means;
an exercise element for manipulation by a user, said manipulation imparting a motion to said exercise element;
torque transmission means, operably connecting said rotary driving means and said exercise element, for providing a resistance to said user's manipulation of said exercise element and allowing for lost motion between said rotary driving means and said exercise element, said torque transmission means transmitting torque from said rotary driving means to said exercise element, said transmitted torque being of a magnitude that is substantially indepenent of said exercise element motion and is dependent only upon said speed of rotation of said rotary driving means.
