Abstract
The system assisting the movement on steep surfaces provided with a cam mechanism is characterized in that the cam mechanism (5), which is a bistable system holding the wheels (1) in contact with the substrate (2) and the second one raised vertically above the first one, wherein the wheel (1) is connected with the connector (3), through which the axis (4) of the cam mechanism (5) passes in the middle of its length, which is composed of the ellipsoidal cam (8) rigidly fixed on the axle (4), which is positioned in one of two stable positions by means of the clamp (7), through the spring (6) resting on the body (9) of the mechanism (4). The ellipsoidal cam (8) and the clamp (7) are made of the material providing a low coefficient of friction.
