Abstract
A transport that is manually powered for transporting an injured or disabled person from one location to another. The chair is particularly useful for transporting an injured or disabled person (who is of a heavy weight) up or down a flight of stairs. The chair lift is manually driven by reciprocating hand levers operated by an attendant. A ratchet and pawl mechanism in combination with a brake system, which is continuously set/locked, allows movement of the chair only when the chair is being propelled up a flight of stairs and when an attendant purposefully actuates a hand lever to release the brakes and allow movement of the transporter.
