| Abstract: |
A human powered wheeled land vehicle is disclosed. The vehicle may utilize two or more wheels, including at least one driving wheel and one steering wheel. The vehicle is propelled by use of at least one lever which is positioned such that the operator is able to grasp the lever and move it back and forth perpendicularly to his body in a reciprocating fashion. A drivetrain mechanism translates the reciprocating motion of the lever into rotational motion of the driving wheel. Two levers may preferably be provided so as to allow the operator to provide alternating motion of the levers. A steering handle is provided on at least one of the levers to control the direction of the steering wheel. The operator may preferably be secured to a seat, the seat also having a back rest, while operating the vehicle. The invention has particular application for use as a racing or touring wheelchair when operated by a paraplegic or a lower-limb amputee.

What is claimed and desired to be secured by U.S. Letters Patent is:
1. A human powered land vehicle for carrying an operator, the operator having at least one movable arm, the vehicle comprising:
- support means for supporting the body of the operator;
- a driven wheel disposed at the rear of the vehicle;
- a steered wheel disposed at the front of the vehicle;
- two lever means comprising:
- propulsion means for translating a reciprocating motion of at least one arm of the operator into unidirectional motion of the rear driven wheel so as to propel the vehicle;
- steering means for directing the front steered wheel such that the vehicle may be guided in a left, right, or straight direction, and;
- means for locking the two lever means in parallel, and;
- frame means capable of carrying the support means, the driven wheel, the propulsion means, the steered wheel, the steering means, and the operator.
