Abstract

A swing rotary fitness apparatus is described. A swing base is axially disposed at a center of a bracket having a pair of handles. A pound-force adjuster is disposed between the swing base and the bracket, and elastic elements for restoration are disposed between the swing base and the bracket. In addition, a rotatable seat is disposed on the swing base. When a user rides on the seat, the user exerts a force by lumbar muscles, so as to generate a circumferential motion of synchronous swing and rotation, which increases amplitude of twisting lumbar muscles greatly and thus improves an effect of exercising the waist.

Claims

1. A swing rotary fitness apparatus, at least comprising:

a bracket, wherein a handle is disposed at each of two sides of the bracket, and shaft holes are arranged at a center of the bracket;

a swing base, moveably and axially disposed at the center of the bracket, wherein a shaft coupling portion is disposed on a bottom of the swing base, such that the swing base such that the swing base is moveably and axially disposed at the center of the bracket, and swings reciprocally relative to the bracket;

a pound-force adjuster, moveably and axially disposed between the swing base and the bracket, which generates a resistance when stretched outwards or dressed inwards, so as to increase or decrease a pound force pushing the swing base to swing;

elastic elements for restoration that are disposed between each of two sides of the swing base and the bracket, and are capable of generating a force for the swing base to restore an original positioning after swinging so as to maintain the swing base at the center of the bracket; and

a seat, moveably and axially disposed at a center of the swing base, such that the seat is reciprocally rotatable relative to the swing base.

2. The swing rotary fitness apparatus according to claim 1, wherein the bracket comprises arc foot stands respectively disposed at two sides, and a plurality of cross rods is disposed between the two arc foot stands, such that an area of the arc foot stands expanding outwards is larger than an area of the seat.

3. The swing rotary fitness apparatus according to claim 2, wherein bottoms surrounding the foot stands are each provided with an antislip foot pad.

4. The swing rotary fitness apparatus according to claim 1, wherein fitting pillars for fitting handles on the fitting pillars are respectively disposed on two sides of the bracket.

5. The swing rotary fitness apparatus according to claim 1, wherein a plurality of hook portions is disposed at two sides of the shaft holes at the center of the bracket respectively, and a plurality of hook holes is arranged at the bottom of the swing base, such that two ends of the elastic elements are respectively hooked in the hook portions of the bracket and the hook holes of the swing base.

6. The swing rotary fitness apparatus according to claim 1, wherein the handles are wrapped by antislip foamed plastic.

7. The swing rotary fitness apparatus according to claim 1, wherein an annular slot is disposed on a top of the swing base, and a plurality of rolling elements is disposed in the annular slot, such that the seat is reciprocally rotatable when moveably and axially disposed in the annular slot.

8. The swing rotary fitness apparatus according to claim 1, wherein an adjusting knob for adjusting a pound force when the swing base swings reciprocally is disposed on the pound-force adjuster.

9. The swing rotary fitness apparatus according to claim 1, wherein an end of the pound-force adjuster is axially disposed on a joint seat at the bottom of the swing base, and the other end of the pound-force adjuster is axially disposed on a joint seat at one side of the bracket.
