Abstract
A free walking training machine includes a chassis having a left supporting frame and a right supporting frame, a left swing arm having a left axial portion extending laterally, a right swing arm having a right axial portion extending laterally, a left lifting mechanism, a right lifting mechanism, a first linking unit, and a second linking unit. The left lifting mechanism makes the left swing arm move upward and downward relative to the left supporting frame. The right lifting mechanism makes the right swing arm move upward and downward relative to the right supporting frame. The first and second linking mechanisms are connected with the left and right swing arms for enabling the left and right axial portions and the left and right swing arms to make coordinated movement and move in opposite directions, respectively. The first and second linking mechanisms are operable independently.
