摘要：
The invention relates to a field ground trackless vehicle, particularly to a wheelchair, capable of moving the ladders and to overcome obstacles, such as the profile stage via assistant. A device wheelchair which comprises a frame with chair for handicapped or other device for placing a payload wheels, at least one further, the front support member type grand piano wheels, the soft movements of a stepped profile obstacles, including stairs comprising interconnected an autonomous power supply source, the actuator and movable arms with supporting elements (particularly roller) pivotally mounted near the wheel therebetween, the mechanical brake and the handle on the frame of the goal. The carriage is further provided with at least one back support with a roller on a pivot axis at the free end of which is disposed on the frame with the possibility of adjusting its distance from the axis of the rear wheels. In particular, compliance with conditions (a system of two mathematical relationships):wherein L - the distance from the rear frame supporting wheel axles r m - length of the movable lever (with roller) of the device by sliding the stepped obstacles m - height (arm length plus the radius of its roller) of the back support r - the radius of the wheels l - length of the ladder K - distance mass center (of gravity) with the invalid wheelchairs or other payload from the wheel axis K - distance mass center (of gravity) with the invalid wheelchairs or other payload from the frame α min - angle of longitudinal inclination of its upper frame portion to the horizon, the minimum allowable for the ergonomic requirements (considering anthropological and physiological parameters assistant), the distance from the wheel axis to the arms, the wheel radius and profile of the ladder. The technical result is to increase TECH wheelchair by improving the manageability, improve operational safety, allow for the assistant to temporarily leave the wheelchair of a disabled person on a flight
