ABSTRACT:
The invention targets at providing a foldable structure for a conventional exercise treadmill, especially for a exercise treadmill that has a motor mounted in the front and fixed type armrests. According to the invention the main frame of the exercise treadmill is provided at the front end with a U-shaped base to which armrests are attached. Further, a pressure rod and a telescopic support tube are disposed on two sides of the U-shaped base and the main frame. To fold the exercise treadmill, users lift the rear end of the main frame to a predetermined inclination and then by means of the release of the pressure energy of the pressure rod the main frame will automatically move to an upright folded position juxtaposed with the armrests. Hence the exercise treadmill structure of the invention can reduce the space it occupies when not in use for convenience in storage or delivery. Furthermore, the spread structure can be firmly fixed by a movable steel ball of the support tube.
