CHASSIS OF WHEELCHAIR Russian patent published in 2019 - IPC A61G5/06 

FIELD: transport machine building.

SUBSTANCE: invention relates to transport engineering, in particular to off-road vehicles, and may be used as a propulsor in wheelchairs to overcome staircases of common use. Essence of technical solution of proposed invention consists in the fact that in chassis of wheelchair containing running supports, platform of drive system and device for stabilizing position of platform, running bearings are made in the form of onboard screw propellers consisting of cylindrical rotor with elastic screw crest and rotary heads, device for stabilization of platform position is made in longitudinal plane of wheelchair in the form of ski with two-sided socks, on which elastic ball-shaped wheels are mounted.

EFFECT: use of the proposed technical solution extends the functionality of the wheelchair chassis when moving on solid surfaces (asphalt, concrete, et cetera) with obstacles in the form of thresholds, curbs, escarpments, including public staircases.
