Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a low impact fitness facility, and more particularly to a prolong-tracked elliptical exercise machine that raises a distance of pedal movement to provide greater exercise advantages.
  • 2. Description of Related Art
  • Elliptical exercise machines are very popular low impact fitness facilities, which allow a person to perform a full body exercise at home whilst avoiding high impact activities, so are especially useful for overweight, elderly, pregnant, unfit or unmotivated people. With reference to FIGS. 6 and 7, an elliptical exercise machine comprises a base (40), two poles (41), two linking bars (43), two pedals (44) and a wheel assembly (42).
  • The base (40) has a front end, a rear end and two sides. The poles (41) are mounted oppositely on the two sides of the base (40) near the front end and are mounted pivotally and controllably on the base (40). The linking bars (43) and the pedals (44) are respectively mounted oppositely on the sides of the base (40, are connected respectively to the poles (41) and perform a cyclic movement.
  • The wheel assembly (42) is mounted in the rear end of the base (40) and provides resistance to the pedals (44), thereby forcing a person moves the poles (41) and pedals (44) to work against the resistance to perform exercise.
  • However, the pedals (44) of a conventional elliptical exercise machine are fixed to the linking bars (43). Therefore, a length of the poles (41) and linking bars (43) limit a possible length of pedal (44) movement. Therefore, tall people with a long stride may find the elliptical exercise machine inadequate. Moreover, advantages of the elliptical exercise machine are proportional to stride length so prolonging pedal movement raises user-experience and exercise benefits.
  • To overcome the shortcomings, the present invention provides a prolong-tracked elliptical exercise machine to obviate or mitigate the aforementioned problems.
    • SUMMARY OF THE INVENTION
  • The main objective of the present invention is to provide a prolong-tracked elliptical exercise machine that raises a distance of pedal movement within present structures of elliptical exercise machines, thereby to providing greater exercise advantages at low cost since previous machine tools can be used.
  • To achieve the objective, the prolong-tracked elliptical exercise machine in accordance with the present invention comprises a base, two poles, two pedal assemblies and a wheel assembly.
  • The pedal assemblies are mounted oppositely beside the base and each pedal assembly has a linking bar, a rail and a pedal. The linking bar is pivotally mounted between the corresponding pole and the wheel assembly. The rail is mounted securely on the linking bar. The pedal is mounted slidably on the rail and is synchronized to and moved along the rail by a driving assembly driven by movement of the wheel assembly.
  • Accordingly, the pedal of each pedal assembly is able to move forward or backward relative to the rail. So, when a person steps on the pedals and forces the pedals to move along elliptical tracks, the distance of pedal movement is increased to provide greater exercise advantages.
  • Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
