ABSTRACT:
A manual pace-adjusting mechanism of an elliptical cross trainer having an adjusting rod pivotally attached to both sides of the bottom support frame, respectively. The top end of the adjusting rod is pivotally coupled to an L-shaped connecting rod while the other end of the L-shaped connecting rod is pivotally connected to the treadle plank. A positioning rod is interposed between the adjusting rod and the front upright posts of the elliptical cross trainer by means of a positioning element. As a result, the adjustment of the angle of the adjusting rod enables the change on the vertical position of the treadle planks so that an independent right and left adjustment of the exercise pace is achieved.
