Benefits of technology

The present invention is an elliptical trainer that is designed to provide smooth and stable operation. The invention includes an elastic device unit that connects the base frame and the stepping bars to constantly keep the rear end portions of the stepping bars in proximity to the base frame and also keep the stepping bars in abutment against the bearing members. This arrangement ensures a high level of operating smoothness and stability, and also enhances the smoothness of the trainer's operation.

Problems solved by technology

The aforesaid prior art elliptical trainer can achieve the expected purpose of use, however, because the stepping bars are suspended above the base frame, the rockers can be dragged by the stepping bars to move back and forth relative to the base frame when the user is operating the elliptical trainer, and thus, the rockers bear a high stress, adversely affecting structural stability.
Further, the arrangement with the rockers respectively pivotally connected between the stepping bars and the base frame will also affect the operating smoothness of the elliptical trainer.

Embodiment Construction

[0022]Referring to FIGS. 1, 2 and 3, an elliptical trainer with enhanced stability in accordance with the present invention is shown. The elliptical trainer comprises a base frame 10, a swing unit 20, a pedal unit 30, a damping unit 40, a guiding unit 50, an elastic device unit 60, a constraining unit 70, and a handlebar unit 80.

[0023]The base frame 10 comprises a base 11, and an upright support unit 12 fixedly mounted at the base 11. The base 11 comprises a front side 111, a rear side 112 opposite to the front side 111, an approximately centrally located transverse section 116 and a front bottom frame member 113 located at the front side 111. The rear bottom bar 114 is located at the rear side 112, and a pair of guide members 115 extended along the horizontal axis X and connected between the front bottom frame member 113 and the rear bottom bar 114.

[0024]The upright support unit 12 is located at the front side 111 of the base 11 and connected to the front bottom frame member 113, c...

Abstract

An elliptical trainer includes a base frame, a swing unit axially mounted at the base frame, a pedal unit axially mounted at the swing unit, a damping unit for providing a damping resistance to the swing unit, a guiding unit and an elastic device unit. The guiding unit includes a pair of cranks respectively connected to the damping unit and a pair of guide brackets respectively pivotally connected to the cranks. Each guide bracket includes a guide wheel slidably coupled to the base frame and a bearing member for supporting one respective stepping bar. The elastic potential energy of the elastic device set constantly keeps the rear end portions of the stepping bars in proximity to the base frame and the stepping bars in abutment against the bearing members. The matching arrangement of the guiding unit and the base frame achieves high operating smoothness and supporting stability.
