Abstract
A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.
