WALKING WHEELCHAIR Russian patent published in 2011 - IPC A61G5/04 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to wheelchairs for disabled people, and can be used for movement on both flat surface and on staircase and for overcoming other profile obstacles. Wheelchair contains installed between flat movable panels armchair with back, panels are connected by, at least, three cranks with flat movable support elements. Lower support surfaces of lateral panels and support elements are made in form of skis with elastic toothed protectors. Posterior crank of each of lateral panels is kinematically connected with drive wheels and mechanical energy recuperator. Armchair with back has possibility of turn in vertical longitudinal plane relative to transverse axis of wheelchair body. Movable support elements are installed from inner side of lateral panels. Back wheels have double independent drive, front steerable wheel is installed from inner side of lateral panels behind step. Support surfaces of lateral panels and movable support elements coincide in their contour and have two convex sharp bents. Toothed elastic protector of support surfaces of lateral panels is formed by elastic rotating rollers.

EFFECT: increase of device reliability and its exploitation characteristics due to increase of maneuverability in flat and reduction of total device length; providing smoothness of movement and reduction of loading on drive handles when moving on staircase.
