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, borrow 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.

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.

The stepping machine of the prior art cannot overcome the problem of "dead point". "Dead point" means that the crank mechanism cannot rotate the crank when the crank is in line with the connecting rod.

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

With the above structure, the pedal 17 is restrained from moving along the curved shape of the slide tube 16 between its upper end and lower end. Figure 4 shows the trajectory P1 of the pressing wheel set 19 and drives the pedal 17 to make an arcuate motion trajectory P2. Among them, when the pedal 17 moves to a low point, its angle is slightly forward or close to the horizontal; when the motion reaches a high point, it is more inclined, which conforms to the ergonomics of stepping, striding, or mountaineering, so that the operator does not feel Discomfort. In addition, each of the pressing wheel sets 19 can change the inclination angle according to the curved shape of the sliding tube 16, and when the pressing wheel set 19 moves to a high point, the pressing wheel set 19 is relatively horizontal; when the pressing wheel set 19 moves to a low point, the pressure The cover wheel set 19 is relatively inclined. Thereby, the pressing wheel set 19 can abut against the sliding tube 16.

As shown in FIG. 4, according to the motion device of the preferred embodiment of the present invention, the motion trajectory P2 of the left and right pedals 17 are respectively an arc whose center is approximately directed to a certain part of the user, such as a calf or a foot. The trajectory of the pedal of the prior art exercise device is not ergonomic; however, the trajectory of the pedal 17 of the exercise device 1 of the present invention is ergonomic. In addition, since the crank 14 directly applies force to the foot tube 12, the defect of the conventional pedal with insufficient thrust can be improved, and the ergonomic pedal movement track P2 is matched with the actual step, step, or mountaineering. Close. In addition, the pedal movement track P2 of the exercise device 1 of the present invention is smooth, which can improve the comfort of use and eliminate the "dot point". The so-called "point" refers to the stagnation that the user feels when he steps on it.

Figure 5 is a perspective view showing the operation of the pedal 17 of the exercise device 1 of Figure 2 . As shown in FIG. 5, when the crank 14 overlaps with the linkage tube 15, the left and right pedals 17 are not at the uppermost and lowermost positions, and the left and right pedals 17 can continue to be actuated to avoid the "dead point" of the conventional exercise device. "Defects.
