| 20090111663 | Elliptical exercise machine - An elliptical exercise machine in which a raise angle of an elliptical path can be adjusted consists of a foot base, a pair of arms, a pair of foot pedaling members, and a raise angle member. When handle parts are held by hands, an opposite exercise can be taken by a left and right grip pole, as the arms are coupled to pedal rods, and a roller slides on a link rod. When both feet step on pedals, the pedal rods will slide on the link rods which drive a pulley to operate, by a function of the foot pedaling members, to achieve a purpose of workout. Furthermore, by using the raise angle member, the pedal rods and the link rods will have a change of raise angle, and the raise angle of the elliptical path is adjusted. | 04-30-2009 |

This device preferably includes an isolation system capable of simulating natural forces throughout the entire range of movement in the horizontal and/or vertical plane. A safety/suspension system can be provided, alone or in combination with the isolation system, to resist sudden foot movement in the same direction, yet allows a slow and controlled tilting of the linkages whereby the user may simulate uphill and downhill travel. | 06-17-2010 |
