Abstract
A balance-shifted personal carriage (19) designed for physically challenged persons such as paraplegics confined to wheelchairs. The carriage (19) basically consists of a base frame assembly (13) that supports a seating assembly (15) a pair of free pivoting wheels (18) located in the front, a pair of steerable wheels (20) controlled by the rider and located in the back, and a centrally located power wheel (22) that is controlled by the rider. The balanced-shifted carriage (19) is operated in either of two modes of operation: in Mode 1, the rider shifts their weight backwards to allow the steerable wheels to contact the floor at which time the power wheel (2) is made to rotate to propel the carriage; in Mode 2, the rider shifts their weight forward to cause the steerable wheels (20)to rise and allow the pivoting wheels (12) to contact the floor allowing the rider to pivot and move the carriage away from an obstacle.
