Abstract:
A self-propelled exercise device comprising:a frame having a drive wheel rotatably supported thereupon, and a first pivot axis defined thereupon; a first and a second foot link, each having a foot receiving portion defined thereupon; a coupler assembly which is in mechanical communication with said first pivot axis, and with a first end of each of said first and second foot links, said coupler assembly being operative to direct said first ends of said foot links in an arcuate path of travel; a foot link guide supported by said frame, said guide being operable to engage a second end of each of said foot links, and to direct said second ends along a reciprocating path of travel; a power transfer linkage in mechanical communication with said coupler assembly, and with said drive wheel; whereby when the first end of one of said foot links travels in said reciprocal path and the second end of that foot link travels in said arcuate path, a user's foot supported thereupon travels in a generally elliptical path of travel, and said power transfer linkage transfers power from said coupler assembly to said drive wheel so as to supply propulsive power thereto.
