WHEELCHAIR WITH SUSPENSION

摘要

PROBLEM TO BE SOLVED: To provide comfortable traveling of a wheelchair by easily moving on any small level difference at a sidewalk, a general road, or the like. SOLUTION: Suspensions 1, 12 are fitted respectively, to four supporter frames 2, 19 supporting respectively front/rear pairs of front wheels 6 and rear wheels 11 at the wheelchair. Thus, it is possible to absorb a shock when moving on the level difference with respect to a small level difference, a slope at a sidewalk and projection/recess at a road, to obtain stability by keeping a seat surface to be horizontal on a slope and to reduce vibration made by projection/ recess to travel comfortably.
