Description

sports equipment

technical field

The invention relates to an exercise device, in particular to a step machine.

Background technique

A stepper is a piece of exercise equipment that increases your heart rate, burns calories, and improves heart muscle endurance.

In the traditional stepper design, the user stands on two pedals with predetermined resistance, and the two pedals are lifted alternately by applying force with both feet. The movement of the steps is like continuously going up the stairs, thereby exercising the muscles of the legs and buttocks. Compared with treadmills, steppers have less impact on the legs, but care must be taken when using them to avoid knee injuries.

FIG. 1A and FIG. 1B show the structures of two traditional steppers, and FIG. 1C and FIG. 1D are the motion tracks of the pedals in FIG. 1A and FIG. 1B respectively. Fig. 1A is a structure of fixed-axis single-link, and Fig. 1B is a structure of fixed-axis double-link. The pedal 20 is fixed to the connecting rod 22, and one end of the connecting rod 22 is connected to the shaft 21, so that the trajectory P of the pedal is an outer arc, and its center points away from the user. This kind of trajectory does not conform to ergonomics and cannot simulate actual stepping, Stepping, or climbing.

US Patent No. US20120077645 discloses a stepper, wherein a crank arm applies force to linking units, so that a connecting rod (pedal link) connected to the linking units moves forward and backward. The connecting rod has a rollable anti-friction member pivotally connected with a pedal. When the connecting rod moves forward, the pedals are driven by the rollers to move obliquely forward and upward along the ramp rod. In the above-mentioned structure, the thrust of the pedals rising is insufficient, and it is difficult to simulate actual stepping, striding, or mountain climbing.

About the stepper of existing known technology, also can refer to Taiwan patent I458519, titled " adjustable stepper ", and Taiwan patent I442955, titled patent applications such as " stepper ".

The treadmill of existing prior art may not be able to overcome the problem of "dead point (dead point)". "Dead spot" refers to the link mechanism, when the crank is in line with the connecting rod, there is no way to push the crank to rotate.

This shows that above-mentioned existing stepper obviously still has inconvenience and defect in structure and use, and demands urgently further improving. In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems.
