Selectable stride elliptical
First Claim
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;
a left side arm having a first portion pivotally connected to the left foot link and a second portion pivotally supported by the frame about a second axis;
a right side arm having a first portion pivotally connected to the right foot link and a second portion pivotally supported by the frame about the second axis;
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;
a left link having a first end pivotably connected to the left foot link and a second end operably coupled to the left crank guide;
a right link having a first end pivotally coupled to the right foot link and a second end operably coupled to the right crank guide;
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.

Abstract
An exercise apparatus comprises a frame, left and right foot link supporting left and right foot pads. The left and right foot pads synchronously move out of phase through an elliptical path having an adjustable step height. The apparatus may include left and right side arms pivotally connected to the left and right foot links and pivotally supported by the frame. Left and right cranks eccentrically support left and right crank guides. Left and right links each have a first end pivotably connected to left and right foot links and a second end operably coupled to the left and right crank guides, respectively. A movable adjustment member is connected to left and right flexible members operably coupled to the left and right foot links. Movement of the adjustable member adjusts an extent to which the left and right flexible members wrap about the respective left and right crank guides.
