Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a hair-like synthetic fiber attached to the running surface of an automobile tire or to a fitting for an automobile tire to prevent slipping of the automobile and to be a pollution-free automobile. The present invention relates to tires and fittings for tires.

[0002]

2. Description of the Related Art Conventionally, automobile tires used on snowy roads and icy roads, and as fittings for them, so-called spike tires to which hard steel pins are attached for the purpose of exerting a braking effect on the road surface, and tires to which spikes are attached Wearables have been used. On the other hand, there were sutterless tires that tried to obtain a braking effect using soft rubber.

[0003]

The conventional spike tires and tire fittings to which the spikes are attached have a problem that when used on an asphalt road surface free from snow and icing, the asphalt road surface is scraped off, and car dust that causes pollution is emitted. there were. Therefore, the reality is that the number of local governments issuing ordinances prohibiting the use of spiked tires is increasing today because it is inevitable that a slip accident will occur. On the other hand, suttatres tires have become popular as an alternative to polluting spikes. However, the Suttatres tire had a problem that the braking ability on the frozen road surface was inferior and the risk of encountering a traffic accident increased. The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a non-slip automobile tire having a good braking effect and a fitting for the same without cutting the road surface. Is what you are trying to do. The present inventor has obtained a hint of producing a braking effect without scraping the road surface on the hair growing on the sole of the foot of a Siberian Husky dog. Siberian Husky dogs, known for their sled dogs,
The dog can pull the sled even on ice because of the soft hair that grows on the soles of his feet. The soft bristles intervene between the top surface of the ice and the skin of the sole of the feet to act as a non-slip material, producing a braking effect. The inventor
Taking this as a hint, we conducted repeated experimental research on implanting hairy synthetic fibers in tires and tire fittings, and found that soft hairy synthetic fibers intervene between the icy road surface and the rubber tire to provide a sufficient braking effect. Turned out to get. In particular, hairy synthetic fibers that have been developed and manufactured in recent years are also called new fibers, and have been developed that have excellent ultrahigh strength, abrasion resistance, high heat resistance, chemical resistance, water repellent property, and the like. It has been confirmed that the use of this hair-like synthetic fiber in a tire has a braking effect and sufficient durability.

[0004]

In order to achieve the above object, an anti-skid automobile tire and a mounting tool for the same according to the present invention are constructed as follows. 1. Synthetic and flexible hair-like synthetic fibers (2) (2)
A non-skid automobile tire characterized in that a rubber tire is planted on the running surface (1). 2. A large number of synthetic hair fibers (2) (2) are bundled at one end and wound around a pin portion (3) to form fiber pins (4) (4),
Connect the fiber pins (4) (4) to the running surface (1) of the rubber tire.
The anti-skid automobile tire according to claim 1, which is embedded in 3. A net body (5) made of any reversible material is formed into a net shape and a substantially rectangular shape, and the net body (5) is formed.
Two spring locking members (7) on both sides (6) (6)
In an automobile tire anti-skid net, which is formed by surrounding (7), hairy synthetic fibers (2) and (2) made of a flexible material and having an elongated shape are planted on the upper surface (8) of the net body (5). A non-slip automobile tire mounting device characterized by the above.

[0005]

When the anti-skid automobile tire according to the present invention and the fitting thereof are used for braking, the hair-like synthetic fibers that have been planted are liable to bleed between the tire running surface and the snow or icy road surface. A good braking effect can be obtained due to the interposition of the synthetic fibers. Also, on asphalt roads where there is no snow or icing,
There is no need to scrape the road surface. Moreover, the hair-like synthetic fibers that are planted are consumed very little.

FIG. 2 is a partially enlarged sectional view of a frozen road surface grounding portion. In this embodiment, since the hairy synthetic fibers (2) and (2) implanted in the tire tread are present between the tire running surface (1) and the frozen road surface, a braking effect can be obtained by performing a braking operation. Occurs. The braking effect generated here is not only a synergistic effect due to the combination of the rubber tire and the hair-like synthetic fiber, but also the finely rough unevenness on the surface of the hair-like synthetic fiber and the micro unevenness generated on the surface of the ice. It is considered to be due to the frictional force generated due to the good compatibility. Therefore, it seems that more effective braking effect can be obtained depending on future research and development such as the material and shape of the synthetic hair fibers suitable for the frozen road surface.
