MOTOR POWER DRIVING APPARATUS FOR WHEELCHAIR

摘要

PROBLEM TO BE SOLVED: To prevent one of a pair of left and right driving wheels from idly running by normally and equally grounding the driving wheels in a wheelchair motor power driving apparatus to be attached to a wheelchair for usage. SOLUTION: The motor power driving apparatus 30 includes each base 40 to be attached to the wheelchair 1. A support shaft 50 is attached to the base 40, and a chassis 60 is supported at the center part by the support shaft 50. The support shaft 50 performs a pitching motion with respect to the wheelchair 1, and the chassis 60 performs a rolling motion. The driving wheels 64L and 64R are arranged in the both left and right wings in the chassis 60. The grounding/non-grounding of the driving wheels 64L, 64R is selected by the pitching motion of the support shaft 50. The relative heights of the driving wheels 64L and 64R in grounding with respect to the wheelchair 1 are changed respectively. COPYRIGHT: (C)2004,JPO
