Electric drive attachment for wheelchairs.

摘要

An electric drive attachment for a wheelchair includes an electric motor (2) constituting the input member of the drive, a wheel (6) adapted to touch the ground and to drive the wheelchair by frictional contact with the ground, and the wheel (6) constituting the output member of the drive. The input member and the output member constitute an integral unit carried by a sleeve-like member (22) slidably mounted on a first portion (38) of a mounting member (40) attachable to the wheelchair, and first means are provided to allow the unit to be shifted to, and arrested at, at least two different positions along the first portion (38) of the mounting member (40). In the first position the unit is closer to a reference point on the wheelchair and in the second position the unit is more remote from the reference point.
