Patent ID: 7041038

Claim:
A folding mechanism for a treadmill comprising: a) a main frame having a motor imparting a rotary motion to a worm gear, the main frame being rigidly connected to a base frame with an open side; b) a platform having front and rear rollers on the under surface thereof, a continuous moving belt being rotatable about the platform, the front rollers being slidably connected to the base frame; and c) a shaft mounted on the main frame, a yoke consisting of a crossbar and two supporting arms being rotatably mounted on the shaft, the crossbar having a worm wheel engaging with the worm gear, the free end of the supporting arms being pivotally connected to both sides of the platform, respectively, whereby, when the worm gear is driven by the motor in rotation, the rotary motion of the worm gear is converted by the worm wheel to bring the platform in a flat and in an inclined position for use due to the fact that the two axes of the worm gear and the crossbar are at right angles.
