Abstract

The invention provides an elliptical motion machine capable of adjusting a track of a pedal. The machine comprises a left supporting rod and a right supporting rod which are respectively provided with a front end and a rear end, wherein the front end of each supporting rod is pivoted at an outer end of a crank and can rotate around a circle, while the rear end is pivoted at a bottom end of a swinging arm and can swing from front to back, so the pedal which is supported between the two ends performs cyclic motion along a substantially-elliptical track. The machine is characterized in that: thetop of each swinging arm is suspended on a side frame; each side frame is provided with a first rod body and a second rod body; the first rod body is provided with a top end and the bottom end; the bottom end is pivoted at the bottom of a main frame body of a machine platform; the second rod body is provided with the front end and the rear end; the rear end is pivoted at the top end of the first rod body; and the front end is connected to a driving device and can be driven to move from front to back, so the top end of the swinging arm correspondingly moves from front to back to change the track of the pedal.

Description

technical field [0001] The present invention relates to exercise and fitness equipment, in particular to an elliptical exercise machine (Elliptical) with adjustable pedal tracks. Background technique [0002] The early Chinese patent publication with the publication number 101327366 discloses an elliptical exercise machine with adjustable pedal trajectory. The left and right two cranks of the mechanism, the left and right two support rods of the aforementioned two cantilevers, and the left and right pedals respectively supported by the aforementioned two support rods and guided to move on similar elliptical tracks, are mainly characterized in that the aforementioned two cantilevers It is respectively suspended on the left and right frames. Each frame has a rigidly connected vertical bar section and a horizontal bar section. The bottom rear end of the elliptical exercise machine, the aforementioned cross bar section extends forward from the top of the longitudinal bar sectio...
