An elliptical trainer comprises a base, a rotational mechanism, a left and a right coupling mechanism, and a rising device. The rotational mechanism is arranged on the base. The left and right coupling mechanisms are arranged at a side of the rotational mechanism, respectively. One end of the left and right coupling mechanism couples to the rotational mechanism, and the other couples to a pedal making a moving path. The rising device comprises a frame, two guiders, at least a ladder component, and a driving assembly. The driving assembly comprises a motor, a screw, a tube, a linkage component, and a cable. The tube has internal thread to engage with the screw. The linkage component couples with the tube, and the cable couples with the linkage component and the ladder component. |

1. An elliptical trainer, comprising:
a base; a rotational mechanism mounted on the base; a left coupling mechanism and a right coupling mechanism respectively arranged at a side of the rotational mechanism with one end coupled to the rotational mechanism and another end coupled to a left pedal and a right pedal to make a moving path; and a rising device comprising a frame, two guiders, at least one ladder component, and a driving assembly, wherein: the driving assembly comprises a motor, a screw, a tube, a linkage component, and a cable; the tube has internal thread engaged with the screw; each ladder component comprises one end coupled with one of the two guiders and another end with a wheel contacting a supporting surface or ground; the linkage component couples with the tube; and the cable couples with the linkage component and the at least one ladder component. |
