Description

The present invention relates to a stepper for fitness equipment, and more particularly to a stepper with a load adjusting function.

In recent years, more and more people are living irregular lives, and the rate of getting modern illness is increasing. On the other hand, in daily life where you are forced to live a busy life, it is difficult to make time to go out and exercise, so in recent years, fitness equipment that can be used indoors at any time has become popular, one of which is available. It is a stepper often used in aerobic exercise. As a conventional technique in the present technical field, for example, there is a "stepper" of Patent Document 1, and according to the stepper of FIG. 1 disclosed in this publication, the stepper of the prior art is compact and very convenient to use. It's expensive.

However, the above-mentioned stepper as a conventional technique has the following drawbacks. That is, since one end of the hydraulic shock absorber of the conventional stepper is pivotally contacted with the mounting plate of the base base and the other end is fixedly connected to the mounting portion of the upper rod, the hydraulic shock absorber and the four-link mechanism can be connected. Since the angle between them is fixed and cannot be adjusted, the load of the prior art stepper is always constant. Therefore, for some users, the load is too light to obtain the exercise effect, and for some users, the load is too heavy to use, so the conventional stepper can handle different users. There was a problem that I couldn't do it.
