发明名称 Invalid walker
摘要 An improved walking assistance device which is also specifically adapted for traversing stairs comprises a rigid intertwined open framework supported by a front and rear pair of legs which permit the device to span multi steps in a stairway. The open framework includes forwardly extending arm rails parallel to the slope of the stairs. Other arm rails support a sling seat for the user person. The device is fitted with appropriate hinges for folding reduction in overall size for more convenient portability.
