Abstract (en)
[origin: WO2010031895A1] A method and apparatus for propelling a wheelchair (10), wherein the wheelchair is coupled to a cart (20) which is propelled along a closed circuit track (30) so that the wheelchair moves along a base (31 ), pulled by the cart. The small front wheels (11 ) of the wheelchair are placed on top of the cart, whereby the cart pulls the wheelchair, either continuously or stopping once in a while, so that the large wheels (12) of the wheelchair rotate freely. The cart most preferably has four pivotable wheels (22). The track comprises a circuit-shaped, endless chain loop (33) located in a groove (32) in the base (31), the cart being coupled to the chain. There is at least one gear (36), rotatable by a motor, in connection with the groove for the purpose of propelling the chain.
