Abstract
In an exercise machine, foot platforms may travel in inclined circular paths to establish three dimensional operational characteristics. Platform support members may be rotationally synchronized by connected mechanical components such that they are maintained out of phase with each other by one half of a cycle or 180 degrees in counter rotational directions. Crank synchronization in an inclined plane during operation of the exercise machine may provide three-dimensional foot travel in vertical, lateral and longitudinal directions.
Claims13
An exercise apparatus, comprising:
- a) a frame configured to rest on a flat surface, said frame including a base and a stanchion extending angularly upward from proximate a forward end of said base;
- b) a left crank rotatably mounted on said frame for rotation about a left crank axis;
- c) a right crank rotatably mounted on said frame for rotation about a right crank axis, wherein said left crank axis and said right crank axis are spaced apart from one another;
- d) a left foot support member rotatably connected to said left crank, and a right foot support member rotatably connected to said right crank;
- and
- e) synchronization linkage movably interconnecting said left crank and said right crank in a manner to move said left foot platform and said right foot platform in respective inclined circular paths defining three-dimensional foot travel.
