ABSTRACT:
An equilibrium breaking type load carrying means for use in a treadmill, mainly comprising a running belt, a running board, supporting rails, and motion generating devices capable of producing a regular motion. At least one set of the motion generating device is attached to supporting rails of a treadmill for causing a friction media underneath a foot surface of the running belt up move to and down with respect to the running belt. As a result, load carrying means of the invention can disturb the equilibrium of forces between the running board and the running belt, resulting in a decrease in frictional forces. Consequently, the performance of a treadmill is significantly enhanced and the difficulties in design and production are decreased.
