しかしながら、このように提案され実施されている従来
法によるものには、次の如き欠点がある。However, the conventional methods proposed and implemented have the following drawbacks.
従来法1.においては、高温で長さが約2mある加硫金
型内でスパイクを正確な位置に長さ15〜20mの芯材
を網目に組みながら固定することは困難であり、この網
目の上に、更に被覆はゴムを充填する手間と相俟って非
能率的である。又、網目組み作業を能率よく行うため、
補強芯材入り未加硫ゴム紐を用いると、スパイクが芯材
に固定されない欠点と、スパイク位置が少しでもづれる
と不良品となり、かつ金型を破損する等の欠点とがある
。Conventional method 1. In , it is difficult to fix the spikes in accurate positions in a vulcanization mold with a length of about 2 m at high temperatures while assembling a core material with a length of 15 to 20 m in a mesh, and on top of this mesh, Furthermore, the coating is inefficient due to the labor involved in filling it with rubber. In addition, in order to efficiently perform mesh assembly work,
When an unvulcanized rubber cord containing a reinforcing core material is used, there are disadvantages such as the spikes not being fixed to the core material and the disadvantages that if the spike position is even slightly shifted, the product will be defective and the mold will be damaged.
従来法2.成形金型内の正確な位置にスパイクを配置し
ないと、金型を破損する欠点と、車の走行中に弾性体が
伸びてスパイクが脱落する欠点がある。Conventional method 2. If the spikes are not placed in the correct position within the mold, the mold will be damaged, and the elastic body will stretch while the car is running, causing the spikes to fall off.
従来法3.車の走行中にスパイクがタイヤと路面圧力に
よりしぼり出されて裏側より脱落する欠点がある。Conventional method 3. The drawback is that while the car is running, the spikes are squeezed out by the pressure of the tires and the road surface and fall off from the back side.
従来法4.スパイクタイヤ用のスパイクは、脱落を防ぐ
ことから、10.5mmの高さを持たせる。しかし、こ
のため網目帯の厚みが過大となる欠点と、スパイクを打
込む付近を過大に補強しないと、スパイクが脱落する欠
点がある。Conventional method 4. Spikes for spiked tires have a height of 10.5 mm to prevent them from falling off. However, this has the disadvantage that the thickness of the mesh band becomes excessively large, and that the spikes may fall off unless the area where the spikes are to be driven is excessively reinforced.
従来法1〜4に用いる釘状の硬質スパイクは、硬い平滑
な路面即ち凍結した路面においてしか有効でない。更に
硬質で断面積の小さいため、路面に対して点荷重として

箇所の弾性体の設計高さが過大となる。このため走行安
定性が悪くなったり、スパイクが垂直に路面を把握しな
くなる欠点がある。The nail-shaped hard spikes used in Conventional Methods 1 to 4 are effective only on hard, smooth road surfaces, that is, frozen road surfaces. Furthermore, since it is hard and has a small cross-sectional area, it acts as a point load on the road surface, causing significant wear and tear on the road surface. In addition, in order to bury a nail-like object in an elastic body so that it does not fall off, it is difficult to bury the nail-like object in the elastic body. There is a drawback that you will not be able to grasp the road surface.
従来法5.取付けが容易で、滑り止効果が大きいのに路

硬度の金属を選定しても、乾燥路面においては150k
m〜25Qkmで脱落する欠点がある。Conventional method 5. It has the advantages of being easy to install, having a high anti-slip effect, causing little damage to the road surface, and not falling off even when subjected to excessive stress.However, if soft metal is used, it will wear out quickly and fall off. If a hard metal is used, the strain caused by bending it into an elliptical shape will cause metal fatigue, and this will overlap with the metal fatigue due to repeated stress during running, causing it to fall off quickly. Even if you select a metal with appropriate hardness, it will only reach 150k on a dry road surface.
It has the disadvantage that it falls off at m~25Qkm.
本発明は、かかる従来法によるものの欠点を改良し、少
ない手間で安価に、かつ走行中の脱落がなく耐摩耗性に

提供し゛ようとするものである。The present invention improves the drawbacks of the conventional method, and provides an automobile tire that is inexpensive with less effort, does not fall off during running, has excellent wear resistance, is durable, and has an anti-slip metal fitting that has an excellent anti-slip effect. The present invention aims to provide a non-slip device and a method for manufacturing the same.
従来法は前述の欠点があることに着目し、本発明者等は
