Abstract
An exercise device includes a pair of foot engaging links. The first end of each link is supported for rotational motion about a pivot axis and a second end of each foot link is guided in a reciprocal path of travel. The combination of these foot link motions permits the users foot to travel in an inclined, oval path of travel. This natural foot action exercises a large number of muscles through a wide range of motion.
Claims7
An exercise device comprising:
- a frame having a fixed pivot axis defined thereon, said frame configured to be supported on a floor;
- a first and a second foot link, each having a foot engaging portion;
- a first and a second coupling member, each associated with a respective one of said foot links for pivotally coupling said foot link to said pivot axis at a predetermined distance therefrom so that a first end of said foot link travels in an arcuate path about said axis;
- a first and a second guide member, each guide member being supported by said frame and operative to engage a respective one of said foot links and to direct a second end of said foot link along a preselected, reciprocating path of travel, which is generally inclined with respect to said floor, as the first end of said foot link travels along said arcuate path;
- so that when said exercise device is in use, and when the second end of one of said foot links travels from a point at a lower end of said inclined path, upward along said inclined path, the heel portion of a user's foot associated therewith initially rises at a faster rate than the toe portion, and when the second end of said foot link travels downward, along said inclined, reciprocating path of travel, the heel portion of the user's foot initially lowers at a faster rate than the toe portion.

- so that when said exercise device is in use, and when the second end of one of said foot links travels from a point at a rearward end of said reciprocating path, forward along said path, the heel portion of a user's foot associated therewith initially rises at a faster rate than the toe portion, and when the second end of said foot link travels rearward along said reciprocating path of travel from a forward end thereof, the heel portion of the user's foot initially lowers at a faster rate than the toe portion.
