    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 aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

    Abstract translation: 产生无马达腿部动力的弯曲跑步机，使得人们不必对跑步机进行任何调整，而不必将用户的重心向前和向后移动，从而步行，慢跑，跑步和冲刺。 在前后皮带轮之间运行的闭环跑步机带形成有以弹性方式彼此附接的横向铝，木，塑料，橡胶或碳纤维板条的低摩擦运行表面。 由于跑步机的基本特征是皮带在其各自的上部的行进表面的凹形，所以跑步机配置确保在实际使用中保持该形状。 这些构造防止凹面上运动表面部分在前和后皮带轮之间被拉紧成平坦的形状。
