Abstract
A stepper structure includes a base having a shaft at a central section thereof to connect a rotation seat. Two pedals are pivotally connected to two sides of the rotation seat. A link unit is pivotally connected to the shaft and located above the rotation seat. When the rotation seat and the base are confined, the two pedals are moved up and down for an up-and-down step exercise. When the link unit and the base are confined, the rotation seat is linked to swing by the up-and-down movement of the pedals for a waist swing and step exercise, providing a different function of the stepper.
Claims3
A stepper structure, comprising a base, a rotation seat, two pedals, a link unit, and a switch unit:
- the base having a shaft at a central section thereof, the base having a first limit portion in front of the shaft, the base having a second limit portion behind the shaft;
- the rotation seat comprising a seat rod and a vertical rod at a front end of the seat rod, the seat rod having a rear section which is pivotally connected to the shaft, the rotation seat having a first limit portion in front of the shaft, the first limit portion of the rotation seat corresponding in position to the first limit portion of the base, the seat rod comprising a pair of support bars extending from two sides of the front end of the seat rod;
- the two pedals being pivotally connected to two sides of the vertical rod, a pair of resistance members being connected between rear ends the two pedals and the two support bars;
- the link unit being pivotally connected to the shaft, the link unit linking the two pedals to move up and down, the link unit having a second limit portion behind the shaft, the second limit portion of the link unit corresponding in position to the second limit portion of the base;
- the switch unit comprising a fixing frame connected on the base, an upper end of the shaft of the base being connected to the fixing frame, the fixing frame having a second limit portion behind the shaft, the second limit portion of the switch unit corresponding in position to the second limit portion of the base, the switch unit further having a limit member which is selectively connected to the first limit portions or the second limit portions.
