摘要
An elliptical exercise device has a frame and guide link pivotally attached thereto. A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. Vertical control tracks are pivotally connected to the frame and support the foot support links. A vertical drive is coupled to the forward portion of the frame and vertical control elements connect the vertical drive to the vertical control tracks. A horizontal drive and horizontal control links control pivoting of the guide links.
