Abstract:
1. An apparatus, comprising: a frame having at least two wheels coupled to the frame, at least one of which is a drive wheel; a first pivot axis defined upon the frame, a bearing at the pivot axis; a first and a second foot link, each having a first end, a second end, and a foot receiving portion defined thereupon; a coupler assembly which is in mechanical communication with said bearing at said 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 track supported by said frame, said foot link guide track 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 arcuate path and the second end of that foot link travels in said reciprocal path, an operator's foot supported thereupon travels in a generally elliptical path of travel with a stride length greater than 17 inches, and said power transfer linkage transfers power from said coupler assembly to said drive wheel, so as to supply propulsive power thereto, wherein the foot link guide track is an internal guide track system, such that the second ends of the foot links are internally disposed within the guide track system.
