Abstract:
A treadmill includes a treadmill that comprises a base and a belt frame has a first end pivotably connected to the base and a second end of the belt frame is a free end. An endless belt is mounted to the belt frame. A support frame is pivotably connected to the base and is driven by a mechanism so that the support frame can be pivoted relative to the base to lift the first end of the belt frame to adjust the inclination of the belt frame. The support frame may support and lift the whole belt frame to fold the belt frame upright.
Abstract:

Abstract:
A height adjustable device is received in the inner tube which is retractably inserted in an outer tube, and includes a base which is fixed in the inner tube and two stop plates are pivotably connected of the base. Two respective first ends of the two stop plates extend through apertures defined through the inner tube and are in contact with two respective insides of the outer tube so as to position the inner tube. A member is movably connected to the base and includes a driving portion for pivoting two respective second ends of the two stop plates. A cable is connected between the movable member and a pivotable member fixed to the inner tube. The pivotable member is pivoted to pull the cable and the two stop plates are pivoted inward so that the inner tube can be freely moved in the outer tube.
