Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention
The present invention is related to a fitness equipment, and more particularly, to a swing stepper to allow its user while reciprocally twisting his/her waist, alternatively bends and pulls straight both legs to step on a pair of pedals for coordination to simultaneously achieve purpose of the swing exercise by twisting waist and simulating treading.
(b) Description of the Prior Art
Generally, fitness equipment simulates the motions that would have been done outdoors so to allow the user to work out within a confined area attempting to achieve the same fitness results given outdoors. For example, a stepper allows the user to alternatively tread on a pair of pedals for achieving sports and exercise purposes.
Steppers generally available in the market share the similar basic construction as illustrated in FIG. 1 of the accompanying drawings. Both front ends of a pair of pedal assemblies A are pivoted to a base 10 and coupled to a hydraulic cylinder B through a connection mechanism (not illustrated) to take advantage of damping provided by the hydraulic cylinder B for both pedal assemblies A to alternatively reciprocate up and down in coordination. Reciprocation of both pedal assemblies driven by the hydraulic cylinder B creates proper resistance to demand more force application from the user.
However, the stepper appeals to provide a general workout purpose. When compared to other types of fitness equipment such as a walker or a stationary bike the stepper giving advantages of smaller size and lower price provides sports effects only limited to both legs even though coordination of motion from other parts of the body is required. A fitness equipment having a horizontal turntable disposed to a base is also available in the market for the user to step on the turntable while twisting his waist to reciprocally turn around the turntable. However, it provides only the exercise of one's waist and is considered as fitness equipment with comparatively less functional since it is unable to work out simultaneously with other parts of one's body.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a swing stepper for its user to achieve at the same time the exercise results of twisting waste and simulating walk. To achieve the purpose, a stepper is disposed axially at a certain inclination to a base. Two pedals are respectively provided at two distal locations corresponding to the stepper. The user twists his/her waist to drive the stepper to reciprocally swing. Meanwhile, a handle bar is axially provided to the base that turns around in synchronous with the stepper. Whereas the swing object is disposed at a certain inclination to the base, both distal ends of the stepper swings up and down alternatively in the course of the reciprocal swing by the stepper to allow the user alternatively bends or pulls straight both legs to step on the pedals in coordination with the motion of twisting.
