Description

  The present invention relates to a running belt underboard structure of a kind of running machine. In particular, it is installed on a kind of running machine and is related to an underboard structure that supports the weight of the running belt and human body.

  A running machine is a machine that can be placed indoors and provide running exercise at any time to people who cannot exercise outdoors or have time. 1 and 2 show the structure of a known running machine. The known running machine includes a running belt 2 installed on a base, and the running belt 2 is manufactured from a flexible material having high strength and high elasticity. Moreover, it has a loop shape and is wound between the main belt belt 3 and the passive belt wheel 4. The main driving belt wheel 3 rotates under the control of a motor, and thereby the running belt 2 is interlocked to perform continuous circular rolling. Since an athlete steps on the running belt 2, it is necessary to install an underboard 1 having sufficient strength on the lower surface of the running belt 2. An athlete's feet run on the running belt 2 and are supported by the underboard 1 when the running belt 2 is sunk.

  Since the running belt 2 continuously circulates on the underboard 1, friction is generated between the lower surface of the running belt and the upper surface of the underboard. Further, the weight applied by the runner on the running belt increases the frictional force. Therefore, in order to avoid rapid wear of the running belt and the underboard, all known running machine underboards are processed with a smooth mirror surface on the upper surface to reduce the coefficient of friction between the running belt and the underboard to a minimum. Yes.

  Although the friction coefficient can be reduced by machining the upper surface of the underboard of a known running machine into a mirror surface, the friction coefficient between the underboard and the running belt cannot be further reduced on this basis. Running machine running belts and underboards cannot extend their life. Moreover, since the contact area between the underboard and the running belt is relatively large, the load on the motor is relatively high, power is wasted, and a relatively large noise is generated during operation of the running belt. Therefore, the main problem to be solved by the present invention is to solve the problem that the upper surface of the known running machine underboard is flat.

In order to solve the above problems, the present invention provides a running belt underboard structure for a running machine described below.
It has a plurality of concave holes or tanks on the upper surface of the underboard, and each of the concave holes or concave tanks is used to store lubricating oil or lubricant so that the running belt circulates on the upper surface of the underboard. When using the running belt, the lubricating oil or lubricant mediates the lubrication between the underboard and the running belt, thus reducing the coefficient of friction between the underboard and the running belt, avoiding the running belt from being rapidly worn. Can extend the service life,
The underboard is provided with a plurality of concave holes or concave tubs on the upper surface thereof, and the upper surface is processed into a smooth mirror surface, thus the friction coefficient can be further reduced by its complementary synergy.
The concave hole installed on the underboard can be a circular concave hole, and the concave hole can be molded into any other shape,
The concave tank installed on the underboard can be a vertically long concave tank that extends along the length direction of the underboard, can be a horizontally long concave tank along the width direction of the underboard, and is inclined. Can be a concave tank, can be a V-shaped concave tank, can be a short concave tank,
With the above underboard structure, it is possible to extend the time to wear of the running belt and the underboard, to extend the service life, to reduce the running belt rolling noise, Reduce the contact area of the running belt, reduce the load on the motor, you can get a power saving effect,
Furthermore, a plurality of convex ribs can be formed on the surface of the underboard, and when the sole of the runner steps on the running belt, the effect of the sole massage can be produced by the action of the convex ribs.

The invention of claim 1 is that the running board underboard structure of the running machine is installed on the lower surface of the running belt of the running machine,
Since the upper surface of the underboard and the lower surface of the running belt are in contact with each other, the running belt is supported and the weight acting on the running belt is supported.
A plurality of depressions are installed on the upper surface of the underboard, and the depressions are filled with a lubricant / agent, and the lubricant / agent plays a role of mediation between the underboard and the running belt. It has a running belt underboard structure for the characteristic running machine.
The invention of claim 2 is the running belt underboard structure of the running machine according to claim 1, wherein the depressed portion is a plurality of circular holes.
According to a third aspect of the present invention, there is provided a running belt underboard structure for a running machine according to the first aspect, wherein the depressed portion is a plurality of vertically long concave tanks.
The invention of claim 4 is the running belt underboard structure of the running machine according to claim 1, wherein the depressed portion is a plurality of horizontally elongated tanks.
According to a fifth aspect of the present invention, there is provided a running belt underboard structure for a running machine according to the first aspect, wherein the depressed portion is a plurality of obliquely recessed tanks.
The invention according to claim 6 is the running belt underboard structure of the running machine according to claim 1, wherein the depressed portion is a plurality of V-shaped recessed tanks.
The invention of claim 7 is the running belt underboard structure of the running machine according to claim 1, wherein the depressed portion is a plurality of short concave tanks.
