  • Patent number: 5147266
    Abstract: A stretching machine for performing the Chinese split includes a base, two generally horizontal tracks extending colinearly from the base, a foot platform sliding on each track, and a vertical column with handles. The user stands on the platforms, which travel outward from the base while the split is performed, and maintains balance by holding the handles. The platforms are moved along the tracks by cables fixed to either side of each platform. The cables run over pulleys to a drum mounted in the column, which can be turned by a crank. A novel aspect is a slight angular inclination between the tracks, allowing a deeper split.
