Description

 Treadmill running belt structure  

This creation is about a treadmill running belt structure, mainly refers to the combination structure of the running belt on the treadmill.

Tracing running belts for treadmills:

(1) In the seventh diagram shown in No. M404032 of the Republic of China New Patent Certificate No. M404032, the front turntable 83 and the rolling member 81 are provided with a concave-convex transmission relationship, that is, each rolling member 81 falls into the front turntable 83. In the corresponding recess 86, the collar 82 is dropped into the opening 88 of the corresponding stop portion 87, that is, each of the rolling members 81 and the collar 82 are respectively recessed and contacted with the recess 86 and the opening 88. contact. Therefore, when the athlete adjusts the running belt and presents a high-speed winding, the area between the rolling elements 81 and the recess 86, the collar 82 and the opening 88 are in contact with each other, causing the running belt to be greatly moved at a high speed. The damping friction force, even if the running belt can still rotate at a high speed, also produces frictional noise and impact sound between the rolling elements 81 and the recesses 86, between the collar 82 and the opening 88, and the faster and louder.

Secondly, since the front turntable 83 has both the recessed portion 86 and the opening 88 and is accommodated by each of the rolling members 81 and the collar 82, the front turntable 83 must have a certain thickness. Therefore, in the actual manufacture of the industry, it is necessary to use the CNC. The manufacturing method of lathe processing or molding (cannot use stamping), in which the CNC lathe processing method has a high unit price, and the molding method requires a high mold cost, so that the cost is slightly lower than the CNC lathe processing method, but the molded product must still be manufactured. Do the surface grinding and the treatment of the appearance (such as electroplating, etc.).

Further, please refer to Fig. 4 of the same, in which the rear turntable 60 is formed with a blocking portion 64 which protrudes from the circumferential surface 63 and is smaller than the radius of the rolling member 31; therefore, the actual manufacture of the rear turntable 60 In addition, it must also be made by the molding method. Similarly, the finished products must be processed by surface grinding and appearance (such as electroplating, etc.).

Finally, the rolling elements 31, 81 of the case are pivoted on the outer side of the two ends of the carrying unit 22 by the movable member 21, and are slid on the rail 41, that is, the rolling members 31 corresponding to the two ends of the carrying unit 22 (rolling members 81) The linear distance between them must be greater than the lateral length of the carrier unit 22. Therefore, when the player steps on the carrying unit 22 for a while, since the supporting point of the carrying unit 22 completely falls on the rolling member 31 (rolling member 81) outside the two ends, when the player steps on the continuous carrying unit 22, the carrying unit The middle portion of 22 is liable to cause depressions and deformations, which causes problems in the pivotal joint between the carrying unit 22 and the movable member 21 and falls off.

In summary, the whole set of treadmills is so expensive that the price is too high, and it is easy to cause maintenance problems. In today's low-profit era, the products are not competitive and it is difficult to sell in the market.

(b) If the first application (application number: 106129859) proposed by the company is also encountered, the same problem as the above running belt is encountered, that is, the roller 60 is pivoted on the two ends of the elongated plate 70 by the chain 40. The outer side, and sliding on the slide rail 20, the corresponding linear distance between the rollers 60 corresponding to the two ends of the elongated plate 70 is also greater than the lateral length of the elongated plate 70. Therefore, when the athlete steps on the elongated plate 70 for a period of time, since the support point of the elongated plate 70 completely falls on the roller 60 outside the two ends, the middle portion of the elongated plate 70 is likely to be concave, The deformation causes a problem in the pivotal point between the elongated plate 70 and the chain 40.

Therefore, how to improve the combination structure of the running belt and its transmission mechanism to reduce product cost, strengthen the use stability and reduce the maintenance probability is the goal of the related industry.

In view of the conventional treadmill running belts, high component costs, parts are easily damaged due to poor design, and maintenance frequency and cost are increased.

The present invention provides a treadmill running belt structure comprising: two carriages disposed on two sides of a frame in parallel with each other, the carriage being provided with at least one slide rail, and two sides of the frame And a pivoting seat is fixed in the front and rear positions of the two adjacent carriages; the four-toothed discs are respectively pivoted on the pivoting seats; the two chains are respectively wrapped around the front and rear positions of the two carriages.
