Abstract:
A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse wooden, plastic or rubber slats attached to each other in a resilient fashion, wherein each transverse slat has at least one continuous fin descending downward therefrom.

Claim (Index 1):
A motor-less, leg-powered treadmill, with a curved running surface, comprising:\n a treadmill frame; a front shaft and a rear shaft that are each positioned respectively in a front and rear of the treadmill frame and configured for synchronous rotation; pairs of front and rear pulley rollers attached on opposing ends of the front and rear shafts, respectively; opposing arrays of bearings, arranged as a bearing rails and positioned between the front and rear shafts on opposing peripheral sides of the treadmill frame; and a closed loop treadmill belt arranged to rotate about the pulley rollers synchronously with rotation of the front and rear shafts, while maintaining contact with the bearing rails; wherein the closed loop treadmill belt comprises a plurality of parallel transverse slats that are resiliently interconnected to form the curved running surface; and wherein the bearing rails follow a catenary curve that is inherently defined by a weight of a portion of the closed loop treadmill belt that extends between a 0-degree position of the front and rear pulleys, and a distance between respective central axes of the front and rear shafts.
