Definitions

  • This invention relates to a wheelchair.
  • the first disadvantage associated with a conventional wheelchair, handcycle or the like is that it is extremely difficult to negotiate uneven terrain, such as uneven pavement or a brick laden pathway, not to mention a dirt road, since the wheelchair or handcycle is often not easily maneuverable and tends to tip over on uneven terrain.
  • uneven terrain such as uneven pavement or a brick laden pathway, not to mention a dirt road
  • the chassis of the wheelchair often becomes bent or twisted out of shape through continuous long-term use, especially if a user often travels on a relatively uneven surface.
  • Such a warped chassis not only makes steering of the wheelchair increasingly difficult, but eventually necessitates replacement of the wheelchair altogether.
  • the second major disadvantage associated with known wheelchair designs is that the wheelchairs are relatively heavy and bulky, making transport, fold-up and assembling thereof difficult, especially for a user who is already at a physical disadvantage.
  • the manual difficulties experienced with folding up and assembling of known wheelchairs also increase substantially when the chassis is even slightly warped.
  • wheelchairs are not collapsible, but at best partially foldable, paraplegic persons who are otherwise capable of driving a motor vehicle, are forced to incur huge capital expenses to attach a wheelchair lift mechanism to the roof of their vehicle to enable them to have access to their wheelchair. This is not only an expensive exercise, but also draws often unwanted public attention to such a user.
