Buffering structure of treadmill

Buffering structure of treadmill description/claims

The present invention relates to a buffering structure, and more particularly to a buffering structure of a treadmill to buffer the action route of a support device by means of a rockshaft and a buffering cushion, wherein the buffering structure of the present invention has simple configuration and low cost, and it is able to adjust the buffer route and not easy to get damaged.

In order to protect the user's legs from being hurt by excessive large counterforce created transiently by the runway platform, the common commercial treadmill generally has a buffering mechanism. However, the general buffering mechanism has poor performance and only provides single buffer action. Therefore, it is unable to provide different degrees of adjustment for different users. Accordingly, the exerciser's legs, especially knees and ankles, may get injured easily.

Although the existing exercise treadmill may equip with another buffering mechanism to stagedly adjust the degree of shock absorption. In addition, it has complicated configuration and is easy to get damaged. In addition, it has high cost, resulting in degraded competitiveness. In addition, every user must adjust the buffering structure individually, resulting in the inconvenience in use and affecting the user's desire to use.

In view of the conventional drawbacks, it is an object of the present invention to provide a buffering structure, which has simple configuration and low cost, and it is able to adjust the buffer route and not easy to get damaged.

In order to achieve the foregoing and other objects, a buffering structure is coupled to a treadmill to buffer an action route of a support device. The buffering structure comprises a rockshaft and a buffering cushion. The rockshaft is mounted on the bottom of the support device and pivotally connected to the treadmill. The buffering cushion is connected to the outer surface of the rockshaft.

As a result, the buffering structure of the present invention has simple configuration and low cost, and it is able to adjust the buffer route and not easy to get damaged.
