Abstract:
This paper describes development of a home use stair aid which hang and move a wheelchair. Basic concepts of this device are follows.

1. Available to adapt it to Japanese regular stairs in houses.

2. Hang and move a person with a wheelchair.

3. Fabrication structure to set it on houses without construction.

4. Easy to use for older people.

5. Escape from it without electric power in case of emergency.

6. Work with power supply for home use.

7. Low price to be able to purchase by individuals own.

This device consists of a flame assembled, a H-shape track put on the center of the flame and a main stair aid which run along the track through a rack and pinion mechanism. A motor to hang up a wheelchair, a motor to drive it, a controller, batteries and straps to hang up were in the main part. A remote controller for operation is connected with the main part by a curly code. Batteries are charged at the charge position on the top or the bottom of the track. Returning ten times is available above stairs with 12 to 13 steps after full charge. There are limit switches at the top and bottom of the track for the safety. A result of field tests showed that this device was practical in use.
