Abstract: An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.

Abstract: An equilibrium training device mainly comprises a chassis, a crank component, a pedal and a revolving inertia auxiliary roller set. When the user stands on the pedal for rotary equilibrium training, the belt and the first/second rollers of the revolving inertia auxiliary roller set are pulled together in tune with the rotation of the flywheel, so the swinging uncertainty of the pedal in revolution could be eliminated, such that the pedal could swing smoothly via the inertia of its swinging path, thus avoiding falls due to loss of equilibrium and improving greatly the security, convenience and practicability.

Abstract: An elliptical exercise apparatus with a swinging effect has a pedals, a crank mechanism, a damping mechanism and pedals. A pair of sloping guide rails are arranged symmetrically between the front support and a middle support of a pedestal. One end of the pair of sloping guide rails is arranged laterally. A pair of pedals are arranged separately onto the pair of sloping guide rails and connected with the crank mechanism. A slide guide is steerably set at a front bottom of the pedals and slidably mated with the pair of sloping guide rails. A universal joint is set at the rear bottom of the pedals and is connected to the left and right cranks.

Abstract: An elliptical treadmill with torsional swinging effect having pedestals, a crank mechanism, a damping device and pedals. Two sloping guide rails are arranged symmetrically between the front and middle supports of the pedestal. One end of two sloping guide rails connecting the front support is arranged laterally. Two pedals are arranged separately onto two sloping guide rails and connected with the crank mechanism. A slide guide is set at front bottom of the pedals in a steerable state and mated onto two sloping guide rails in a sliding state. A universal joint is set at rear bottom of the pedals and connected with left and right cranks. With this configuration, this can resolve the limitation of a conventional elliptical treadmill, enabling the pedals to generate both elliptical and torsional swinging movements, bringing the users a different feeling and improving the fitness effect with higher flexibility and applicability.
