Description

Motion device

This creation is about a sports device, especially a stepper.

A stepper is a sports device that increases heart rate, burns calories, and improves myocardial endurance.

In the traditional stepper design, the user stands on two pedals with a predetermined resistance, and the two feet apply force to alternately lift the two pedals, and the action of the footsteps is like continuously going up the stairs, thereby exercising the muscles of the legs and the buttocks. . Compared to treadmills, steppers have less impact on the legs, but care must be taken to avoid knee injuries.

1A and 1B show the structure of two conventional steppers and the trajectory of their pedals. Fig. 1A is a structure of a fixed-axis single link, and Fig. 1B is a structure of a 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 a shaft 21, so that the movement track P of the pedal is an outer arc type, and the center thereof is directed away from the user. Such a movement track is not ergonomic and cannot simulate the actual Step, step, or mountaineering.

U.S. Patent No. 20120077645 discloses a stepper in which a crank arm is applied to a linking unit such that a pedal link connected to the pendulum tube is displaced forward and backward. The link has a rollable anti-friction member pivoted to the pedal. When the connecting rod moves forward, the pedal is driven by the roller and moves forward and upward along the ramp rod. In the above configuration, the thrust of the pedal rise is insufficient, and it is difficult to simulate the actual step, step, or mountaineering.

In addition, the stepping machine of the prior art cannot adjust the size of the stride for different users.

In addition, in the conventional stepping machine, the pedal slides along a defined track, and an abnormal sound is generated.

For the stepping machine of the conventional technology, reference can also be made to Taiwan Patent I458519, entitled "Adjustable Stepper", and Taiwan Patent I442955, entitled "Stepper" and other patent applications.
