Description

Non-slip pedal

The invention relates to a non-slip pedal.

Generally, the anti-slip structure of bicycle pedals is integrally formed on the pedals. For example, a metal pedal integrally forms convex ribs for fitting the soles of the shoes to achieve the anti-slip effect. However, the surface of the metal material is relatively smooth, especially when liquid adheres to it, it will reduce its anti-slip effect, causing the foot to slip easily on the pedal, and it is difficult to step on the pedal stably, which is more laborious.

In addition, the anti-skid pedal of the prior art also directly injects the anti-skid part on the pedal during the molding process. However, this method requires additional mold design, resulting in low degree of change in the shape and shape of the anti-skid part; There is also a direct welding of the non-slip part to the pedal. However, to weld the non-slip part to the pedal by welding, it is necessary to heat the non-slip part at a high temperature, which will damage the result of the non-slip part and affect its structural strength.

Therefore, it is necessary to provide a novel and progressive anti-skid pedal to solve the above-mentioned problems.

The main purpose of the present invention is to provide a non-slip pedal, which combines a non-slip structure with a pedal body to improve the convenience of processing, high degree of variation and bonding strength.

In order to achieve the above object, the present invention provides an anti-slip pedal, including: a pedal body provided with a pedal portion; a non-slip structure provided on the pedal portion, including a non-slip layer and a bonding layer, the bonding layer is bonded to the Between the footrest and the non-slip layer, the composition of the bonding layer includes nitrile rubber (NBR), friction material, fiber material and accelerator; wherein the weight percentage of nitrile rubber (NBR) ranges from 55% to 85% , The weight percentage of fiber material ranges from 1% to 25%, the weight percentage range of friction materials is 1% to 30%, and the weight percentage range of accelerators is 1% to 20%.
