Abstract
A treadmill includes a base and two posts are connected to the two side rails. A frame with an endless belt is pivotably connected between the two posts. Each post has an elongate hole and two sets of pivot assemblies respectively extend through the two elongate holes. Each pivot assembly has a pin and a roller which is mounted to the pin which is fixed to the frame. The roller is movably retained in the elongate hole corresponding thereto. A support device has an end fixed to the base and the other end of the support device is pivotably connected to an underside of the frame. The frame is pivoted upward about the pins and the rollers assist the pivotal movement of the frame. The pins are moved within the elongate holes to adjust the inclination of the frame relative to the base.
