ABSTRACT:
A piece of equipment for the simulation of skiing movements which comprises a basic structure which can be stably placed on the ground. An arm is hinged to the basic structure in a median position and is able to oscillate horizontally. The arm carries a pair of boards at its end. Feet are connected to the structure to incline it with respect to the ground. The arm is able to carry out a slight vertical oscillation. The boards are restrained to the arm so that they can rotate around their vertical and horizontal axes, the rotation around the vertical axis being limited by suitable means. Two rods overhang and are connected to the arm by pins. The rods are able to rotate around the vertical axis of these pins, such rotation being made synchronous with that of the boards. The rotation is opposite to the direction of oscillation of the arm. The piece of equipment is also equipped with an electrical detection circuit which detects correct or incorrect movements carried out by the user who, by placing his or her feet on the boards and gripping the rods, gives an oscillating movement to the arm with the help of elastic devices which absorb and give back the kinetic energy produced, thus carrying out the movements required by skiing techniques.
