  • Publication number: 20090194975
    Abstract: The present invention is a collapsible self-propelled chair on wheels that is lightweight in construction and easily collapsed, carried, stored and transported by public or private means. The chair performs the function of a wheelchair while avoiding the appearance of a traditional wheelchair thus avoiding the invalid stigma often associated with wheelchairs. It can be configured as an assistive mobility device to fill the unmet needs of aging healthy adults who wish to retain their independence and social interactions or a medical device to assist those with medical needs. Additional features such as removable armrest, seat belts, a footrest, or a reclining back are easily added during manufacture and because of the chairs uncomplicated design and duplicity of parts, it is very economical to manufacture.

  • Patent number: 7384058
    Abstract: A foldable wheelchair (21) and foldable wheelchair frame assembly (26, 126) including a pair of side frames (24, 124, 224, 324), a cross-bracing frame assembly (36, 136) coupling the side frames (24, 124, 224, 324) together for movement transversely between a spaced apart deployed position and a proximate folded position. A variable length link assembly (61, 161, 261, 361) is mounted into and forms a part of the cross-bracing frame assembly (36, 136) in a position between at least one of the side frames (24, 124, 224, 324) and a remainder of the cross-bracing frame assembly. The extensible link assembly (61, 161, 261, 361) being formed for variation of the overall length in a direction extending transversely between the side frames (24, 124, 224, 324) during movement of the side frames (24, 124, 224, 324) between the deployed and the folded positions so as not to force the side frames (24, 124, 224, 324) into unparallel motion which causes the upholstery to bind the folding mechanism.
