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 4):
A drive assembly for driving a manually powered wheelchair, comprising:\n a plurality of wheel troughs extending from a front end towards a rear end of the drive assembly, each wheel trough (i) adjustably sizeable to receive therein a rear push wheel of a wheelchair and (ii) comprising a pin oriented substantially perpendicular to a longitudinal axis of the wheel trough; two drive wheels, positioned towards the front end of the drive assembly, for imparting motion to the drive assembly and thereby driving the wheelchair when the rear push wheels of the wheelchair are positioned within the wheel troughs; and a single caster-wheel assembly, positioned towards the rear end of the drive assembly.
