#FIG. 1 is a perspective view of an elliptical stepper in accordance with the present invention.

#FIG. 2 is a partially side plan view of the elliptical stepper in FIG. 1.

#FIG. 3 is a partially exploded perspective view of the elliptical stepper in accordance with the present invention.

#Referring to the drawings and initially to FIGS. 1-4, an elliptical stepper in accordance with the present invention comprises a base 10, a damping device 20 mounted on the base 10, two crank devices 30 respectively laterally mounted to two opposite sides of the damping device 20. Each crank device 30 has a stepping device 40 mounted thereon and each stepping device 40 has a roller set 50 mounted to a bottom thereof, wherein the roller set 50 is universally rolled relative to a corresponding one of the two stepping device 40. The base 10 includes two opposite sides each having a guiding structure 60 disposed thereon. Each guiding structure 60 includes at least one rail 61 having a front end outwardly extending relative to a center line of the base 10. Each roller set 50 is moved along a corresponding one of the two guiding structures 60 such that each stepping device 40 provides a wiggling effect when moved along an elliptical route.

#The base 10 is divided into a front section 11 and a rear section 12 detachably connected to each other. In the preferred embodiment of the present invention, each guiding structure 60 includes at least two rails 61, wherein at least one rail 61 has a front end outwardly extending relative to a center line of the base 10. A rail 61, adjacent to the center line of the base 10, is parallel to the center line of the base 10 and the other at least one rail 61 is curved. A handle 13 is disposed on the front section 11 of the base 10.

#The damping device 20 is mounted onto the rear section 12 of the base 10. The damping device 20 includes a drive wheel 21 and a flying wheel 22 rotatably mounted onto the rear section 12 of the base 10, wherein the driver wheel 21 has an axle 23 centrally extending therethrough. The drive wheel 21 and the flying wheel 22 are simultaneously rotated with each other for providing resistance by using speed ratio and the weight of the flying wheel 22.
