Description

[Detailed Description of the Invention] (A) Industrial Application Field This invention prevents the head of the spike from always protruding outside the tire contact surface, and only when the road condition requires the spike, a small air chamber is placed inside the tire. The air pressure is injected to the same level as the air pressure in the chamber, and the spike operation panel is pushed up to push the head of the spike to the outside of the tread of the tire body to prevent slipping.When the road surface condition does not require spikes, a small amount of air is used. After exhausting the air from the chamber and retracting the spike heads, the tires can be used in the same way as regular snow tires or studless tires.

When road conditions suddenly arise that require spikes while driving, a portion of the air inside the tire is pumped into the small air chamber by operating only the A valve without using an air pump etc. to push up the head of the spike. If the tire of the present invention is installed during the snowy season, there is no need to change the tire until the time when winter tires are no longer needed.Therefore, the following conveniences and industrial applications are possible. wide.

(b) It helps improve work efficiency because it saves time and effort when changing tires.

(b) Even during the snowy and icy season, the driver does not have to worry about sudden changes in road conditions or the vehicle's suspension, and is able to drive in a stable mental state, helping to prevent accidents.

(c) Vehicles can be managed and operated accurately and efficiently.

(d) The road pavement and road markings are not damaged and the road surface is maintained in good condition for a long period of time, which greatly contributes to improving the efficiency of road transportation, and also saves huge road management costs. The cost of road marking management can be reduced.

(B) Conventional technology (a) Conventional spiked tires have a structure in which the spikes are press-fitted from the surface of the tire tread, so the head of the spike always protrudes outside the tire tread. Then, even if the road surface conditions do not require spikes, I always drive as is because I do not carry summer tires or snow tires, and because it takes time and effort to change tires, I always drive as is, and I do not care about road pavement or road markings. They scrape things and generate car dust, and the worn parts of the spikes fly off, causing so-called car dust pollution, which harms people's health.

In Hokkaido and other prefectures, which are areas with heavy snowfall, there are strong calls for the banning or restriction of the use of spiked tires by enacting ordinances, and some prefectures have enacted ordinances to prohibit the use of spiked tires, and there is a growing movement to ban spiked tires. ing.

(b) Recently, there has been a growing demand for the use of studless tires, but studless tires are susceptible to frozen roads and slopes, making it difficult to climb, and they also suffer from reduced driving force, stability on curves, and flatness. Road surfaces become slippery with ice, making it difficult to start, leading to congestion in urban areas and the risk of exhaust gas pollution.

(c) If the use of spiked tires is prohibited, vehicle powder pollution will not occur, but now that the radius of movement of cars has become wider, it is difficult to spray ice melting agents in limited small areas or to perform poor snow removal. At present, where improvements in road surface management and winter tires are not progressing, the number of traffic accidents as a whole has increased dramatically, and the number of accidents resulting in injury or death is expected to be directly proportional, creating a major social problem.Therefore, there is a strong demand for improvements to roads and winter tires as soon as possible.

(C) Problems that the invention aims to solve Tire manufacturers, road management organizations, research institutes, etc. are working to develop winter tires that do not generate car powder, design roads that do not generate car powder, and apply ice-melting agents to existing roads. We are spending a huge amount of research money, prototype production, and testing costs on spraying, etc., but the problem has not been resolved.

Therefore, a ready-made snow tire or a studless tire can be used as the tire body T, which is economical.

(b) Since the structure of the spike operating body S is not complicated, it is easy to manufacture.

(c) When the road conditions require spikes 8, 8 before the start of work, use a device to inject air into the small air chambers 6, 6, and use the spike operation panels 5, 5.
is pushed up and the heads of the spikes 8, 8 are used to protrude from the ground contact surface of the tread 13 of the tire body T to prevent slipping.

(d) If you suddenly encounter an icy and snowy road while driving without exposing the heads of the spikes 8 and 8, even if you do not carry a compressor or hand-pumped air pump, do not let the air in the tire's inner chamber 17 Part A valve 2
By the operation in step 1, the heads of the spikes 8, 8 can be used by feeding them into the small air chambers 6, 6 and protrude in a short time, thereby freeing the user from the troublesome work of injecting air, and making it possible to immediately respond to road conditions. Measures can be taken.

(e) When the road conditions become such that the spikes 8, 8 are not necessary, the air is discharged from the small air chambers 6, 6 by operating the B valve 22, the heads of the spikes 8, 8 are retracted, and the snow Can run on tires or studless tires.

(F) By installing the tires of the present invention, which can immediately respond to road conditions, whether it is on an icy or snowy road or on a dry road, drivers can drive in a stable mental state, so they can always drive safely and with plenty of time to spare. This will help prevent accidents.

(g) When driving on a road with no snow and exposed pavement, the spikes 8 and 8 hit the road hard, making noise, which bothered tower riders, pedestrians, and nearby residents. However, since the heads of the spikes 8, 8 are retracted when running unless necessary, no noise pollution is generated.

(h) Since the heads of the spikes 8 and 8 are not exposed unless necessary, do not scrape the pavement surface with the spikes 8 or 8, or scratch off road traffic markings such as lines, symbols, or letters with paint, etc. Since there is no scraping, it helps maintain a good paved surface over a long period of time, and saves huge amounts of road paving costs and road marking repair costs.

(li) Since the paved surface is not scraped, no car dust is generated, so it does not harm the health of humans or livestock and helps prevent so-called car dust pollution.

(nu) Spraying ice-melting agents on paved roads will cause roadside trees to wither. Negative effects such as groundwater contamination, rust on cars, and damage to road surfaces are expected, and it is said that ice melting agents are less effective when snowfall of 5 cm or more occurs intermittently or when the temperature drops below -10 degrees Celsius. Spraying the ice melting agent every time requires a huge amount of road management costs, and it is difficult to fully implement the spraying of ice melting agent due to financial aspects of road management and environmental issues.
