Abstract
The revised Variably Configured Wheelchair is proposed, which can locate the safe position on an escalator steps instantaneously. The measuring rod attached in front of the wheelchair is pressed against an escalator step riser in order to set the wheelchair constant distance and to work the parallel link. I case of descending, the center of gravity locates out of step. Therefore, regular 20inch tire diameters should be reduced to 14inch. The stopping mechanism is developed in order to keep the wheelchair within the safety area. The parallel link mechanism push the lower link by the rod reaction force to the escalator step surface in order to keep the sheet posture horizontal. The toggle link is applied for magnifying the operation force.
