ABSTRACT:
A shallow rectangular frame supports a pair of free-running elongated rollers parallel to each other and spaced suitably to cradle the main wheels of a conventional wheelchair. A gentle ramp ahead of the rollers enables a wheelchair occupant to drive the wheelchair backwards up the ramp and roll the wheels into the roller cradle. A transverse backstop guards against overrunning the cradle. With the main wheels of the wheelchair in the roller cradle, the front wheels of the chair are supported by the ramp. An adjustable brake at the front roller provides for variable exercising effort and also brakes or locks the roller so that the chair may be easily driven out of the roller cradle and down the ramp.
