Abstract:
A retrofitable drive assembly attaches and detaches quickly, easily, and reversibly from a conventional, manually powered wheelchair and is employed to convert the manually powered wheelchair into an electrically powered wheelchair. The drive assembly includes a plurality of wheel troughs, each adjustably sizeable to receive therein a rear push wheel of the manually powered wheelchair, regardless of the wheelchair's size and its rear push wheels' dimensions. In addition, the drive assembly includes two drive wheels positioned towards a front end of the drive assembly and a single caster-wheel assembly positioned towards a rear end of the drive assembly.

Claim (Index 23):
A method for driving a manually powered wheelchair having two rear push wheels, the method comprising the steps of:\n (i) positioning each rear push wheel of the wheelchair within a corresponding, adjustably sizeable wheel trough of a drive assembly by reversing each rear push wheel of the wheelchair over a ramp of its corresponding wheel trough, each wheel trough extending from a front end towards a rear end of the drive assembly and the ramp of each wheel trough being positioned at the front end of the drive assembly, the drive assembly further comprising:\n two drive wheels, positioned towards the front end of the drive assembly; and \n a single caster-wheel assembly, positioned towards the rear end of the drive assembly; and \n (ii) actuating the two drive wheels to impart motion to the drive assembly and to thereby drive the wheelchair.
