Description of the Invention: [Technical Field] The present invention relates to a structure of an elliptical machine, and more particularly to an elliptical machine structure that increases the supporting force on a rear section of a pedal that can be rotated. [Prior Art] The elliptical system is a fitness machine that simulates the movement mode when a person walks. The user steps on the pedal of the elliptical machine and approximates the circular shape with a motion trajectory. ©. Front and rear fitness In order to achieve full-body exercise and fitness, the 'stepping design can avoid the impact damage to the lower limbs of the user, so it has recently been widely used by users. ^ Please refer to Fig. 8 and Fig. 9'. The figure shows a conventional rounding machine structure in which the two grips 8 1 are connected through the two links 8 2 and the two pedals § 3, and the two slides. The rods 8 4 are interlocked. When the user stands on the pedal 83, each of the sliding levers 8 4 moves forward or backward, each of the grips 81 will swing in a clockwise or counterclockwise direction and transmit through the transmission device 85. One end of the sliding rod 84 will rotate with the crank 86, and the other end of the sliding rod 84 will slide in the rail seat 87, so that the pedal 8 3 on the sliding rod 8 4 follows an approximately elliptical path. . Each of the pedals 8 3 can be moved in a clockwise direction or a counterclockwise direction by the pin 8 8 as a center of rotation, and the front and rear pitches are generated. However, there is no support before and at the rear end of each of the pedals 8 3 , so the user goes to the 201016262 because the angles of the front and rear pitches are too large to affect the smoothness of the operation of the elliptical machine, resulting in discomfort when pedaling, and even more There are flaws that cause sports injuries. Furthermore, the front and rear ends of the pedals 8 3 are often insufficiently affected by the supporting force, which directly affects the service life of each of the pedals 83. Therefore, the elliptical structure of the prior art has a space for improvement. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a structure of a rounding machine. The two simple connecting rod structures are respectively connected to a sliding rod and a front portion of a pedal, and the rear portion of each connecting rod By simple bending, a supporting force can be provided on the rear section of the pedal to increase the overall strength of the connecting rod and the pedal, and extend the service life of the connecting rod and the pedal. Another object of the present invention is to solve the above problems and provide an elliptical machine structure in which the front portion of the pedal has a high degree of reference with respect to the link, whereby the pedal is pivotable to be close to the user.

The sole of the foot, and the rear end of the pedal 6 is disposed on the support base 54 to provide an appropriate angle for the front and rear pitch of the user, and the rear portion of the connecting rod 5 can be simply bent 'Providing a support force to the rear of the pedal 6, reaching the increase in the strength of the connecting rod 5 and the pedal 6 and extending the service life of the connecting rod 5 and the pedal 6. Furthermore, by designing the cushioning member 53 of the bottom surface of the pedal 6, the function of cushioning and damping can be provided at the rear end of the pedal, so as to enhance the comfort during use, and increase the operation time. Degree and safety during exercise. The above description of the embodiments is intended to be illustrative of the invention and is not intended to limit the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the above-mentioned objects, and is in accordance with the provisions of the Patent Law.
