Abstract

PROBLEM TO BE SOLVED: To solve the problem of a wheelchair: that if a wheelchair user moves by her/himself through an uphill passage (road), the wheels need to be kept rotated without stop, and if the force of advancing the wheelchair cannot be maintained because of the relationship between the grade of the road and the weight of the wheelchair (including the user's weight), the wheelchair comes to a stop, resulting in a very unstable condition if there is no time to brake; that is, the user must either avoid an upgrade or pass with fear or, if the user gives up advancing on her/his way, the wheelchair must be turned around on site; in either case, dangers may arise unless the wheelchair is designed to allow an instantaneous stop without depending on the user's physical strength. SOLUTION: A wheel reversal prevention device using stopper jaws is attached to every kind of wheelchair, including those currently in use, so that the user can move through even a sloping passage (road) by her/himself with peace of mind. Thus, the range of activities of a care giver is enlarged and a secondary effect arises which reduces the burden of a nurse or the like who pushes the wheelchair by hand in a hospital, etc.
