Abstract
A ramp transportation system for a wheelchair enables transportation, deployment, and retrieval of a portable ramp by a single wheelchair occupant in the absence of external aid. The device comprises: a platform, configured to support the width of a wheelchair for crossing the platform, having a sufficient stiffness to support a wheelchair and occupant load; a lifting mechanism interface in the platform, disposed at least near each end of the ramp, configured to support cantilever lifting forces on the ramp; a lifting element, configured to engage the lifting mechanism interface and to apply a force to raise and lower the platform between a raised, stowed position and a lowered position, suitable for traversal; and a motor, configured to supply sufficient force on the lifting element to raise and lower the platform.
