Patent ID: 8628454

Claim:
A sports training machine, comprising: a frame having a front end and a rear end, a first rotational axis, and a second rotational axis, wherein each of the rotational axes provides 360 degrees of rotation, a first pivotal axis, and a second pivotal axis, with the two rotational axes installed on the same end of the frame; two pedal bars and two pedals, each of which is installed on a separate one of the pedal bars in a sliding way; wherein each of the pedal bars pivotally connects to the first pivotal axis by a point other than the two ends thereof; one end of each of the pedal bars is pivotally connected to a first linkage, which in turn pivotally connects to the first rotational axis; each of the pedals pivotally connects to one end of a corresponding second linkage; the other end of the second linkage pivotally connects to the second rotational axis; a pivotal portion is provided between the two ends of the second linkage to pivotally connect each pedal to the second pivotal axis; an up-down reciprocal motion of the pedal bars drives the first linkage to rotate the first rotational axis; and a forward-backward reciprocal motion of the pedals drives the second linkage to rotate the second rotational axis, so that the pedals perform upward-downward and forward-backward reciprocal motions.
