Abstract

A running belt structure of a running machine is characterized in that a plurality of adjacent anti-slip strips are arranged on a running belt, and foot contact surfaces of the anti-slip strips are arc surfaces. The foot contact surface of the anti-slip strip is an arc surface, the horizontal shear force peak value in the front-back direction of the running belt is obviously lower than that of the traditional running belt, the reduction of the shear force in the front-back direction is greatly helpful for a runner with unstable lower limb joints, and the sport injury of a user caused by the overlarge shear force in the front-back direction in the running process can be reduced.

Description

The structure of the running belt of the treadmill

technical field

The invention relates to the field of fitness equipment, in particular to a running belt structure of a treadmill.

Background technique

At present, most of the innovative technologies of traditional treadmills focus on the improvement of cushioning technology, which is expected to reduce the risk of sports injuries caused by excessive impact force during running. However, in the innovative development process of treadmills, only vertical attention is often paid The ground reaction force in one direction is ignored, and the reaction force in other directions is ignored. As shown in Figure 5, the tread of the running belt of the traditional treadmill is a rectangular structure, which is only a non-slip texture. According to previous studies, forefoot runners have lower knee shear forces in the anterior and posterior directions, so runners with less stable knee joints are recommended to adopt forefoot running posture; heel runners have lower hip, The shear force in the anterior and posterior directions of the ankle joint is recommended for runners with unstable ankle joints to adopt a heel-running posture. According to previous research results, it was found that reducing the front-to-back shear force is of great help to runners with unstable lower limb joints; in addition, the running belt of the treadmill runs from front to back through the motor, which may cause runners to touch the feet. Therefore, how to reduce the shear force in the front and rear directions of the treadmill is one of the issues that practitioners in the field need to solve urgently.

SUMMARY OF THE INVENTION

In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a running belt structure of a treadmill.

The utility model relates to a running belt structure of a treadmill, wherein a plurality of adjacent anti-slip strips are arranged on the running belt, and the contact surfaces of the feet of the anti-slip strips are arc surfaces.

The foot contact surface of the anti-slip strip is an arc surface, which can reduce the shear force in the front and rear directions when the foot touches the ground, thereby reducing the shear force in the front and rear directions given to the runner when the running belt runs from front to back.

The beneficial effects of the present invention are:

The contact surface of the foot of the anti-slip strip of the present invention is an arc surface, and the peak value of the horizontal shear force in the front and rear directions of the running belt of the present invention is significantly lower than the peak value of the horizontal shear force in the front and rear directions of the traditional running belt. Unstable runners are of considerable help and can reduce sports injuries caused by excessive shearing forces in the front and rear directions during running.

Detailed ways

As shown in FIG. 1 and FIG. 2 , a running belt structure of a treadmill, the running belt 1 is provided with several adjacent anti-slip strips 2 , and the contact surface of the feet of the anti-slip strips 2 is an arc surface 3 .

As shown in Fig. 3, the contact surface of the foot of the anti-slip strip 2 is an arc surface 3, which reduces the shear force in the front and rear directions when the foot touches the ground, thereby reducing the amount of force given to the runner when the running belt runs from front to back. Shear force in the front-to-rear direction.

As shown in Figure 4, it is a schematic diagram of the comparison of the horizontal shear force in the front and rear directions of the traditional running belt and the inventive running belt. The contact surface of the foot of the anti-slip strip 2 of the present invention is an arc surface 3. The peak value of the horizontal shear force in the front and rear directions of the invented running belt is significantly lower than that of the traditional running belt. Reducing the shear force in the front and rear directions is of great help to runners with unstable lower limb joints, and can reduce the user's running time. Sports injuries caused by excessive shear force in the front and rear directions during the process.

Claims (1)

1. The utility model provides a running belt structure of treadmill, is provided with a plurality of adjacent limited slip strips (2) on its running belt (1), its characterized in that: the foot contact surface of the anti-slip strip (2) is a circular arc surface (3).
