WHEELCHAIR-STEP WALKER Russian patent published in 2018 - IPC A61G5/00 

FIELD: satisfaction of human vital requirements.

SUBSTANCE: invention relates to wheelchairs with electric, allowing to overcome common stairs. Essence of the technical solution proposed by the invention is that in a wheelchair-step walker, basis of which is a vehicle with a two-dimensional inertial navigation device that allows the user to maintain balance on two individually-driven wheels located on both sides of the user's seat, equipped with tracks and the mechanism of angular displacement and fixation of tracks with respect to the user's seat, the tracks are mounted on axles on the outside of the wheels, and the mechanism of angular displacement and fixation of the tracks with respect to the user's seat is made on a lever fixed by one side to the wheel axis and the other side carrying articulated parallelograms transmitting rotation from the disk/pulley on the axis of the electric drive to the track pulleys, the disk/pulley of the drive axle has a flange that is in non-slip contact with the flange attached to the vehicle body coaxially with the track pulley mounted on the lever. Track can be spanning the drive pulley and the track pulleys. On the long side of the triangular element, non-driving rollers and/or rollers can be mounted under the support track run.

EFFECT: technical result of the use of the present invention is to expand the functionality in terms of permeability, stability and safety of electric wheelchairs on the common stairs.
