Abstract: A human-propulsion-system utilizing an arm lever assembly and a pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly is reciprocated to provide power and rotated left or right to provide a movement for (steering) control. Both the arm lever assembly and the pedal assembly are operatively connected to a converter, utilizing gears and clutches, that receives the reciprocal movements of the arm lever assembly and the rotational movements of the pedal assembly and converts them into a combined unidirectional output configured to be utilized in combination or independently. The arm lever assembly is further telescoping and offers a range of various leverages by changing the length of the force end when extended and retracted.

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.

The arm lever assembly is reciprocated to provide power and rotated left or right to provide a means of (steering) control. Both the arm lever assembly and the pedal assembly are operatively connected to a converter, utilizing gears and one-way clutches, that receives the reciprocal movements of the arm lever assembly and the rotational movements of the pedal assembly and converts them into a unidirectional output, to be utilized in combination or independently. The arm lever assembly is further telescoping and offers a range of various leverages by changing the length of the force end when extended and retracted.
