Abstract
Abstract A hand-propelled chariot or vehicle is shown which is particularly useful for crippled individuals. The chariot has a frame having a seat portion, a seat back and left and right side arms, and an extended front foot platform. Rear wheels support the seat portion relatively close to the ground, and the height of the front foot platform is about half the height of the seat portion giving the chariot a low profile to facilitate mounting and dismounting by a crippled person. Hand crank operated, chain and sprocket, direct drives are connected to each rear wheel to turn same in either direction. Castors are mounted to support the front foot platform and permit the chariot to turn. A friction brake is connected to the rear wheels to hold the chariot steady during mounting and dismounting.
