  • Patent number: 5951357
    Abstract: A magnetic strip of material formed into a loop which is placed around two pulleys. The pulleys rotate, thereby moving the magnetic strip. Skiers have skis which are attracted to the magnetic strip and are thereby moved with the loop as the loop is pulled around the pulleys. As the skier reaches the top of the upper pulley, the ski is lifted off the magnetic strip and onto the ski jump ramp. At the top of this ramp, the skier is held by a magnet located beneath the top of the ramp. Rotating with the upper pulley is a cam which moves the magnet at the top of the ramp between two positions. The first positions holds the magnet against or adjacent to the underside of the ramp holding the skier at the top of the ramp and the second position holds the magnet rotated slightly away from the ramp which releases the figure to descend the ramp and perform its ski jump. Optionally there is a flag that drops when the magnet releases the skier.
