Abstract

Improvements in a flywheel friction loading measurement system is disclosed. The measurement system includes combining a rotational system that alters friction on a flywheel combined with a variable resistor or potentiometer. The combination proves a measurable system that can determine the loading on a piece of exercise equipment. The potentiometer is calibrated to provide a repeatable and reliable measurement of the loading system that is placed on a flywheel. Detents can be included to provide finite loading positions. A calibration sequence can also be used to communicate the friction to a display and measurement system. The rotational system is with pulling a cable on a rotational axis or with wrapping a cable chain, belt or equivalent on or around a rotational axis.

Claims18

Dependent claims

An exercise machine resistance brake calibration mechanism comprising:

a rotatable knob on a housing;
said rotatable knob being connected to a capstan through a shaft;
said capstan is secured to a first end of a cable, and said cable passes through a shank near said first end of said cable that is secured to said housing;
said cable terminates at an end cap at a second end of said cable that is connected to a braking system on said exercise machine wherein;
rotation of said rotatable knob wraps said cable on said capstan and alters a tension on said first end of said cable that in-turn alters said braking system that is connected to said end cap of said cable, and
a potentiometer connected to said shaft, whereby a position of said rotatable knob is measured as a resistance of said potentiometer that corresponds to an exercise resistance on said exercise machine.
