<p>PROBLEM TO BE SOLVED: To allow a wheel chair to smoothly and safely ride over a level difference in a house even if no helper exists by extending a handrail upward from the inclination of a level difference slope. SOLUTION: A back 10 formed as an almost flat surface to be arranged along a level difference C1 and an inclination 20 formed to be inclined downward from the almost top of the back 10 are provided. A handrail B10 is extended upward from the inclination 20. On the surface of the inclination 20, an antiskid means is desirably formed. The handrail B10 can be constructed by a pipe material or the like to be formed into an almost U-shape in a side view, into an almost T-shape in a side view, into an almost pole-shape in a side view or the like. In this way, a wheel chair can smoothly and safely ride over a level difference in a house even if no helper exists.</p> |
