Motion device

Abstract

The invention relates to a motion device. The motion device provided by the embodiment of the invention comprises a framework, two pedal plates, two swing tubes, two pedal tubes, a resistance device, two cranks, two linkage tubes, two support mechanisms, two swing tubes and two adjustment devices, wherein each swing tube is provided with a part pivoting framework, one end of each swing tube is provided with a handle, the other end of each swing tube is pivoted to one end of the corresponding pedal tube, and the other end of the corresponding pedal tube is connected with the corresponding pedal plate; one end of each crank is connected with the axis of the resistance device, the other end of each crank is connected with one end of the corresponding linkage tube, and the other end of the linkage tube is pivoted to the area of the pedal tube; the first end of each swing tube is pivoted to the fulcrum of the corresponding support mechanism, the second end of each swing tube is pivoted to the area of the corresponding pedal tube, and the adjustment devices are used for adjusting the distances between the second ends and the fulcrums. With the motion device, the lifting thrust of the pedal plates can be promoted, the practical pedaling, striding or mountaineering movement can be stimulated, the generation of abnormal noises can be avoided, and thus an operator feels comfortable.

Description

technical field [0001] The invention relates to an exercise device, in particular to a step machine. Background technique [0002] A stepper is a piece of exercise equipment that increases your heart rate, burns calories, and improves heart muscle endurance. [0003] 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. [0004] Figure 1A and Figure 1B It shows the structure of two traditional steppers and the trajectory of their pedals. Figure 1A It is a fixed-axis single-link structure, and Figure 1B It is a fixed-axis double-link structure. The pedal 20 is fixed to the connecting rod 22, and one end ...

AI Technical Summary

Problems solved by technology

In the above-mentioned structure, the thrust of pedal ascending is insufficient, and it is difficult to simulate actual stepping, striding, or mountain climbing

[0006] In addition, the conventional steppers cannot adjust the size of the stride for different users

[0007] In addition, in the prior art stepper, the pedal slides along the limited track, which will produce abnormal sound
