Abstract: Personal transportation aid that can be converted easily between a wheelchair and a walker. The device has handles that can be pushed forward to switch from wheelchair mode to walker mode. Pushing the handles forward causes the seat bottom of the wheelchair to flip up, opening a space where the user can stand to use the walker; the front wheels of the wheelchair are also pushed forward. Pulling the handles backwards returns the device to its wheelchair configuration, with the seat bottom flipped down and the front wheels moved backwards. Simple mechanical linkages may be used to flip the seat bottom up and down, and to push the front wheels forward and backwards; therefore the device does not require a power source or actuators.

Abstract: A stair cage is a stair assistance apparatus having a rail attached to the wall on each side of a staircase, and two horizontal rails spaced horizontally apart but joined by cross bars and having wheels rotatably attached to the ends of the cross bars and engaged in tracks within the horizontal rails so that the cross bars are able to move up and down the stairway. A brake system having a brake assembly in the wheels and squeeze brake handles on the cross bars so that the user can control the descent or hold position on the ascent.
