ABSTRACT:
The invention relates to an improved adjustment mechanism to the anchoring angle of the rear supporting beam in a treadmill. It has two positioning plates along the two sides near the bottom of a treadmill frame. That bottom surface near the outer edge is equipped with a stop piece. The rear supporting beam is then attached via the holes on the extended parts to the positioning plates. Two connecting pieces are used to mount a coupling over a through axle, placed between two corresponding holes on the two extensions from the rear supporting beam. The two connecting pieces are connected to a threaded bar and the other end of the threaded bar is put through a punched hole on the supporting beam. A turn knob is threaded over the bar exposed outside the supporting beam to complete the assembly. By turning the turn knob on the threaded beam, it could be used to shift the rear beam's anchoring angle can be adjusted to further achieve the fine-tuning of the slanting angle of a treadmill frame.
