초록 ▼

This invention relates to a power drive unit which is attachable to, and detachable from, a conventional wheelchair. Thus, a conventional manually-powered wheelchair can be converted into a power driven wheelchair employing the subject apparatus for driving and directing the movement of a manually-driven wheelchair having a plurality of wheels riding on an underlying surface. The subject apparatus comprises a drive and steering wheel which rides on the underlying surface for driving and for directing the path of operation of the wheelchair, as well as for powering the drive wheel. The apparatus is attachable to, and detachable from the wheelchair and is located rearwardly of the wheelchair so that the weight on the drive and steering wheel will substantially only be the weight of the apparatus. On the other hand, the weight of a person sitting in the wheelchair will be substantially the only weight imparted to the wheelchair wheels. The power steering and driving operations are continuously conducted using the drive wheels, without regard to substantial direct downward forces imparted to the drive wheels by the wheelchair user. The unit preferably comprises a single rear-wheel drive motor and wheel unit.
