Lateral glide elliptical exercise machine with yaw control

摘要

A lateral glide stationary elliptical exercise device (10) with foot support platform (90) yaw control. Yaw control is achieved by a four bar dual rocker linkage yaw control mechanism that includes (i) a foot link (70) with a pair of laterally offset first (p5) and second (p9) connection points constrained to move through generally elliptical paths within parasagittal planes, (ii) a glide link (80) pivotably connected at a first end to the first connection point (p5), (iii) a drawbar (100) pivotably connected at a first end to the second connection point (p9), and (iv) a foot support platform (90) pivotably connected proximate a second end of the glide link (80) and proximate a second end of the drawbar (100).

1. A stationary elliptical exercise device comprising:
(a) a frame defining a longitudinally and transversely extending sagittal plane, and (b) left and right foot supporting linkages, each including a four bar dual rocker linkage that includes:
(i) a foot link operably supported on the frame for movement of a pair of laterally offset first and second connection points on the foot link through generally elliptical paths within parasagittal planes,(ii) a glide link pivotably connected at a first end to the first connection point on the foot link for pivoting about a first transverse pivot axis, and operably constrained for coordinated pivoting about the first transverse pivot axis as the first connection point moves along the generally elliptical path,(iii) a drawbar pivotably connected at a first end to the second connection point on the foot link for pivoting about a second transverse pivot axis, and(iv) a foot support platform pivotably connected proximate a second end of the glide link and proximate a second end of the drawbar at laterally offset third and fourth connection points on the foot support platform for pivoting about a third and a fourth transverse pivot axis respectively,(v) whereby yawing of the foot support platform about a yaw axis of the foot support platform is reduced by the drawbar as the first and second connection points of the foot link travel along the respective generally elliptical paths.
