Body-building apparatus with oval track

Abstract

The invention relates to an elliptical orbit exerciser, which comprise a frame unit, a transmission unit which is arranged on the frame unit, two swinging units which are arranged on both sides of the transmission unit opposite to the frame unit, and two pedal units which are arranged on both sides of the two swinging units and the transmission unit, wherein edges on both sides of the transmission unit are respectively provided with rotating wheel cranks which are extended towards the center and are positioned on both ends of the same axial line; the swinging units are respectively provided with a swinging arm which is convexly extended upwards from the bottom of the frame unit; an extension rod is pivoted between the swinging arm and the end part of a rotating wheel crank on the same side; and the intermediate section of the extension rod is pivoted with a pedal lever which is spanned on a second end of the rotating wheel crank. When a user stands on the pedal units on both sides, two legs can generate interlaced elliptical orbit motion with large span and small riser height; and the elliptical orbit exerciser not only can improve the sport effect but also can avoid ankles from suffering from sport injury due to small variation of the pitch angle of the ankles, and can further simplify the structure and reduce the volume.

Description

Technical field [0001] The invention relates to the field of fitness equipment, and a fitness equipment that allows the legs to produce front and back staggered elliptical trajectories. Background technique [0002] Press, the track exerciser is a kind of foot training equipment that uses both feet to move along the crank trajectory of the transmission wheel. The early structure is like figure 1 As shown, the conventional track exercise machine is provided with an upwardly extending column 11 at the front end of a machine base 10 placed on the ground, and an armrest bar 12 is pivoted on both sides of the column 11, and a rear end of the machine base 10 The transmission wheel 13 with damping effect is provided with a crank 14 extending in the opposite direction on both sides of the transmission wheel 13, and a foot lever 15 is provided between the free ends of the two cranks 14 and the end of the corresponding armrest rod 12. The middle section of the step rod 15 is respectively ...

AI Technical Summary

Problems solved by technology

[0009] The mini-treadmill of the foregoing patent seems to have reduced the size of the traditional elliptical track fitness machine, and also has the action of staggered strides, but it mainly uses Narrowing the diameter of transmission wheel 32 comes, but its striding distance is because transmission wheel 32 diameters become smaller, and then becomes smaller, and it can only do the staggered movement of small steps, and because its transmission wheel 32 diameters are little, so every The cycle time of the steps is very short, forming a jogging action, which cannot be adjusted according to the amount of exercise the user is doing. At the same time, the jogging action for a long time is also prone to instability of the center of gravity, resulting in accidental injuries, which is still not satisfactory. General Consumer Fitness Needs

[0010] In other words, due to the large size of the Xi-style elliptical track fitness equipment, there are complex structures and high manufacturing costs. safety, causing it to take up space no matter when it is used, placed, stored or transported, which invisibly reduces consumers' willingness to buy

[0011] In view of this, the inventor has made in-depth discussions on the problems of the aforementioned fitness equipment being too large or having poor exercise effects. R & D and manufacturing experience, actively seeking solutions, through continuous efforts in research and trial production, finally successfully developed a small elliptical trajectory fitness equipment with a large span, so as to overcome the excessive size of the previous elliptical trajectory fitness equipment inconveniences and disadvantages
