The invention relates to an alpine ski simulator which accurately reproduces the movements of the skis on the track during the slalom contest, being meant for indoor skiers' training and for teaching alpine ski to amateurs. According to the invention, the simulator comprises a tray () provided with a boss on its front part on which a bushing () is fixed by screws (), a bolt () being pressed into said bushing and rotatably supporting two oscillating frames (), a gearmotor () having an arm () provided with a channel in which a ball-headed bolt () is fixed with a nut () and rotatably supports, by means of an articulation (), a shoe () with a resilient ring (), the said shoe () guiding in a vertical channel of the first frame () and converting the rotary motion of the arm () into oscillatory motion, a lever () articulated on a bolt () fixed onto the second frame (), into the lever () there being pressed two bolts () having two bearings () guiding in two channels of two plates (), the lever () amplifying the amplitude of the oscillation of the second frame () in relation to the first frame (), in order to achieve the lateral oscillation transmitted to two profiles (), four connecting rods () articulated on four bolts () pressed into the second frame (), two straps () fixing the ends of the connecting rods () to the lateral ends of the lever (), by means of four bolts (), for achieving the axial oscillations of the two articulated profiles (), two plates () provided with some inclined channels in which two rollers () guide, rotatably supported on a bolt () for achieving the angular oscillations of the profiles () and a display device () displaying a film with virtual o real images representing a slalom ski track with christie turns, taken with a camera placed on a skier's forehead. |
