A stair chair

摘要

A chair includes a seat (30), a backrest (34), a foot rest (32), upper handles 84 and lower handles (82). Three wheels (62) are mounted at each side of the chair. The wheels are pivotal about their own axis and also a common axis. Rotation about the common axis can be braked or locked. The chair can be lowered downstairs with a person pulling on the upper handle (84) and another person pushing on the lower handles (82) in order to slow movement of the chair down the stairs.
