All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A manual pace-adjusting mechanism of an elliptical cross trainer, comprising:
a frame unit with a bottom support frame at a front end of the frame unit and a flywheel transmission unit at a rear end of the frame unit, a top of the frame unit being provided with a fixed handle rod;
two movable handle rods with each movable handle rod being pivotally mounted on a crossbar between two upright posts;
two connecting rods with one end of each of the connecting rods pivotally connected to a bottom of each of the movable handle rods;
two treadle planks cooperatively linked to the flywheel transmission unit, an other end of each of the connecting rods being pivotally connected to a front section of each of the treadle planks;
two adjusting rods with each of the adjusting rods being pivotally attached to opposite sides of the bottom support frame;
two L-shaped connecting rods with one end of each of the L-shaped connecting rods being pivotally coupled to a top end of each of the adjusting rods and an other end of each of the L-shaped connecting rods being pivotally connected to each of the treadle planks; and
two positioning rods with each of the positioning rods being interposed between each of the adjusting rods and each of the front upright posts of the elliptical cross trainer by means of a removable positioning element,
wherein adjusting an angle of each of the adjusting rods enables the independent adjustment of the vertical position of each of the treadle planks to allow independent adjustment of an elliptical path of an operator’s right and left feet.
