View Patent ↗An adjusting device of stepping exercisers is movably connected to slots in a base on a frame and a flexible member is connected to the adjusting device. Two ends of the flexible member are respectively connected to two links of the two pedals. When the adjusting device is adjusted to a higher position, the two pedals are positioned at higher positions, and are positioned at lower positions when the adjusting device is lowered.
1. A stepping exerciser comprising:
a frame includes a base extending therefrom and two slots defined through two walls of the base, a post connected to the frame and a handlebar connected to a top of the post;
two pedals respectively pivotably connected to the base, and
an adjusting device connected to the base and movably secured to the two slots, a flexible member connected to the adjusting device and two ends of the flexible member connected to the two pedals said adjusting device includes a U-shaped frame, a pulley connected to the U-shaped frame, the flexible member engaged with said pulley, a position bolt extending through the slots and the adjusting device and secured to a nut; and an adjusting bolt which extends through a top of the base and is connected to the U-shaped frame.
2. The exerciser as claimed in claim 1 , wherein the flexible member is a steel cable.
3. The exerciser as claimed in claim 1 , wherein the two pedals are connected to two links respectively and the two respective links co-axially connected to the base and two cylinders respectively connected between the base and the two pedals.
4. The exerciser as claimed in claim 3 , wherein the two links each have a protrusion extending from a side thereof and the two ends of the flexible member are connected to the two protrusions respectively.
5. The exerciser as claimed in claim 3 , wherein two support frames are respectively connected to the two pedals and the two links and cylinders are pivotably connected to the two support frames.
6. The exerciser as claimed in claim 5 , wherein two bottom boards are rotatably connected to the two support frames and the two pedals are fixed on the two bottom boards.
7. The exerciser as claimed in claim 6 , wherein each of the two bottom boards includes two stop members extending from an underside thereof so as to limit the angle that the pedals rotate relative to the support frames when the two stop members contact the support frames.
