Abstract
A human-propulsion-system utilizing a telescoping arm lever assembly and an optional pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly and the pedal assembly can be utilized in combination or independently further being operatively connected to a converter that utilizes gears and clutches to receive the reciprocal movements of the arm lever assembly and the rotational movements of the pedal assembly converting them into a combined unidirectional output. The arm lever assembly utilizes a slide mechanism that correspondingly moves the load end closer to the fulcrum point when the arm lever assembly is extended and correspondingly moves the load end farther away from the fulcrum point when the arm lever assembly is retracted offering a range of adjustable leverages. The arm lever assembly is further rotated left or right to provide a means of (steering) control.
