Selectable stride elliptical

摘要

An exercise apparatus comprises a frame, a left foot link supporting a left foot pad, a right foot link supporting a right foot pad in a left foot link supporting a left foot pad. The right foot pad is linked to the left foot pad so as to synchronously move out of phase with the left foot pad through an elliptical path having an adjustable step height and an adjustable stride length. An adjustment synchronizer is operably coupled to the left foot link and the right foot link to synchronously adjust both the step height and the stride length of the elliptical path.

主权项

1. An apparatus comprising:
a frame; a left foot link supporting a left foot pad; a right foot link supporting a right foot pad, the right foot pad being linked to the left foot pad so as to synchronously move out of phase with the left foot pad through an elliptical path having an adjustable step height and an adjustable stride length; and a left flexible member having a first end operably coupled to the left foot link; and a right flexible member having a first end operably coupled to the right foot link; a left crank guide; a right crank guide; a left crank eccentrically supporting the left crank guide relative to a first rotational axis about which the left crank is rotatable; a right crank eccentrically supporting the right crank guide relative to the first rotational axis about which the right crank guide is rotatable; an adjustment synchronizer operably coupled to the left foot link and the right foot link to synchronously adjust both the step height and the stride length of the elliptical path, wherein the adjustment synchronizer comprises:
a movable adjustment member connected to a second end of the left flexible member and a second end of the right flexible member, wherein movement of the adjustable member adjusts an extent to which the left flexible member wraps about the left crank guide and the right flexible member wraps about the right crank guide to adjust a step height synchronously with adjustment of a stride length of paths through which the left foot link and the right foot link move.
