A wheelchair with a platform for transporting a standing rider in addition to a rider sitting in the wheelchair. The wheelchair is self-propelled by a motor coupled to drive one or more ground/surface contacting wheels. The platform on which the additional person stands is attached to the chair frame preferably with pivot-allowing structuring at one edge of the platform and at the back end of the wheelchair. The platform is selectably positionable in a first position and second position. The first position being one which the platform is horizontally disposed for being stood on by a rider, and the second position being one wherein the platform is on edge, or pivoted approximately 90 degrees upward to a stored position more closely adjacent the wheelchair. The platform includes two small diameter 360 degree swivel casters or wheels which contact the ground for supporting the distal end of the platform when stood on by a rider. The pivot attachment of the platform to the wheelchair also serves as a live axle or pivot during use, allowing the platform to pivot and change angle relative to the wheelchair when the casters encounter bumps or elevational changes. Controls for motion and steering are provided for the chair occupant, and preferably duplicate controls are positioned for the rider behind the chair occupant. |
