发明名称 SIMPLE STAIR CLIMBING DEVICE FOR WHEELCHAIR
摘要 PROBLEM TO BE SOLVED: To enable climbing in an S-shaped meandering section and a steep slope section and enable high speed climbing in an ordinary section such as a straight section and a slope having a comparatively gentle grade. SOLUTION: In the special section such as the slope having S-shaped meandering, a curve part on stairs, a slope on which a degree of inclination is changed, and a steep angle inclination part on stairs, a monorail type climbing device is operated. This climbing device climbs at a low speed by an Abt-system mountain railroad system and enables comparatively high speed operation by a transmission system due to chain driving in the ordinary section such as the straight section and the slope having the comparatively gentle grade.
