Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention allows a small tube to be supplied with a required amount of air according to the road condition only when the road condition requires the spike without constantly projecting the head of the spike to the outside of the tire ground contact surface. Inject it to inflate a small tube to push up the flange support plate and flange, push the spike head out of the grounding surface of the tire body and use it with a non-slip effect to create a road condition that does not require spikes. In this case, the air in the small tube can be exhausted and the head of the spike can be retracted to be used in the same manner as a general snow tire or statless tire. If you suddenly reach a road condition that requires spikes while driving with the spikes retracted, part of the air in the large air chamber of the tire body is diverted to a small tube by operating only the A valve, and the spike head Since it is possible to push up the part and make it anti-slip, if you install the tire of the present invention during the snow season, you do not need to change the tire until the time when the need for winter tires disappears, saving time, efficient operation of the car, Even if there are sudden changes in road conditions, you can drive safely without being distracted by the legs of the car. There is no damage to the pavement surface of roads and road markings, there are conveniences such as reduction of management costs, and it has a wide range of industrial applications.

2. Description of the Related Art Conventional spike tires have a structure in which spikes are press-fitted and embedded from the surface of a tire tread and the head of the spike is always projected and fixed to the outside of the tire tread, so that the pavement surface is exposed. It runs as it is, scrapes road pavement and road markings to generate car dust, which causes so-called car dust pollution, which harms human health.

Although the use of sutter-less tires is becoming widespread, it is weak on frozen roads and slopes, making it difficult to climb a plate, reducing stability on a driving force curve, and starting on a smooth, icy road on a flat road with a lot of traffic. Often has problems.

In the present situation where the radius of action of the vehicle is wide, the vehicle in which the spike tire is worn outside the designated area of the law cannot pass without removing the spike tire when entering the designated area at a short distance. However, it is thought that traffic accidents will increase and it will lead to a serious injury resulting in a serious injury due to the fact that the snowmelting agent is sprayed in a limited small area and the road management for poor snow removal and tire improvement are not progressing. Improvement is strongly requested.

[0005]

In order to solve the problems described in the section of the prior art, tire manufacturers, road management institutions, research institutions, etc. design roads that do not generate car dust, and use snow-melting agents on existing roads. Although we are striving to disperse, etc., by enormous research costs and trial test costs, the solution is still slow. The present invention is for ordinary residents and vehicle suffering from such a car dust pollution
It was invented in order to meet a wide range of demands such as persons , tire manufacturers, road management organizations, research organizations, and enforcement organizations.

EXAMPLES Examples will be described with reference to the drawings. 1 to 5, in the present car society, it is necessary to comfortably use a car that can be said to be an instrument of civilization, while not adversely affecting others, injuring others and maintaining own safety. The effects of using spiked tires on the health and environment of the residents have been debated for a long time, and in order to eliminate their adverse effects, the "Act on the Prevention of Spike Tire Dust Generation" was promulgated last year, and the interest of the residents was raised. Although it is currently deepening, we are actively agreeing to use statless tires because it resonates with the prevention of accidents.
There is a lot of snow and the road freezes, and in places where there are slopes, it is scary to run unless it is a spike. There is a great deal of anxiety if it is not spiked tires, because each driver has experienced dangers when driving with a vehicle other than spiked tires. In early winter, when the temperature is high and snow is extremely low, we are refraining from using it due to the de-spike, but when the cold becomes stronger, the road surface freezes, and there is more snow,
The current situation is that many transportation companies and ordinary residents are changing to spike tires. Carrying tires for changing shoes at all times and changing tires during running are also poor in practicality, and the spike tire of the present invention can immediately solve the problem.

As shown in FIGS. 1 and 2, when the spike 11 is inserted into the tread 17 of the tire body T and used for a long period of time, the head of the spike 11 hits the road surface strongly, and the rubber portion of the tread 17 is gradually worn away. In the case where the spike 11 is slightly wobbled, the wobble is stopped by filling the wear portion between the spike steadying member 20 and the tread 17 with a solid molten rubber liquid.

As shown in FIGS. 1 and 2, the flange 12 of the spike 11 receives the air pressure of the small tube 7 by the flange support 10 and pushes up the flange 12 to project the head of the spike 11. Since the impact force becomes stronger as the blade strikes the flange support 10, the area of the flange support 10 is made as wide as possible.

Although a small amount of rainwater enters through the spike insertion hole 18, it does not enter because it is blocked by the spike return rubber disc 13 and the gap is closed by the air pressure of the small tube 7.

Due to the air pressure in the large air chamber 22, water leakage from the contact portion between the tire body T and the spike operating panel S is caused by the spike operating panel S, the central support panel 5, and the side supporting panel 6 being the inner surface of the tire body T. Since it is pressed against and is in close contact, there is no infiltration of water.

The tread 17 of the tire main body T wears the ground contact surface, and the protrusion of the spike 11 head is slightly excessive.
The problem can be solved by adjusting the air pressure that is injected into the small tube 7.

Since the small tube 7 is protected by the thick tread 17 of the tire body T, it is considered that there are few failures such as puncture, but repair of the small tube puncture is performed by the small tube 7.
Strongly and inject the side of the spike 11 that does not protrude from the head into a malfunction, remove the side connecting bolt 16 near the mounting portion of the small tube 7 and the injecting / exhaust pipe 8, and insert the small tube 7 into the small tube housing groove 1. Just protect from the air pressure of the large air chamber 22,
Since it is thinner than the other wall and can be bent freely, it is bent downward and the small tube 7 is taken out and repaired.

The anti-slip tread of the tire body T of the present invention is preferably a tire having a deep groove in order to prevent slipping when the vehicle is running with the spikes 11 retracted therein and to bite ice and snow.

[0025]

The present invention has been invented for the purpose of preventing generation of car powder and preventing slipping on a road surface in a snowy or frozen state. Although the "law on the generation of spiked tire dust" is banned to be "a metal stud or the like fixed to the ground contact portion of the tire", the present invention is free from snow. On the road, the spike 11 is retracted into the tread 17 of the tire to drive, and on a road with ice, snow or freezing, air is injected into the small tube 7 by an air injection device, or a valve is operated from the large air chamber 22 of the vehicle. The air is diverted to fill the small tube 7 and project the head of the spike 11 to prevent it from slipping. On roads where there is no snow and snow and the paved surface is out, the valve can be easily exhausted and the head of the spike 11 It is legal and rational because it runs without pulling car powder from the ground contact surface.

A tire main body T is made of ready-made snow tires or sutterless tires and is provided with work facilities such as drilling the spike insertion hole 18, the central connecting bolt insertion hole 3 and the side connecting port insertion hole 4, and the spikes are added to the tire main body T. Spike operation panel S equipped with 11, small tube 7, injection and exhaust pipe 8, etc.
If it is manufactured by closely contacting with a plurality of connecting bolts, the structure is relatively simple and economical.

Both of the tire body T and the spike operation panel S need to be vulcanized, but if the tire body T and the spike operation panel S are bonded and produced as a single piece, the structure becomes complicated. However, according to the present invention, the tire main body T and the spike operation panel S are separately manufactured by vulcanization, and they are finally adhered to each other by connecting bolts to form a composition. Therefore, it is easy to manufacture and a robust product is completed.

When traveling using spikes outside the designated area where spikes are prohibited, and when entering the prohibited area, exhaust is performed by operating the valve, and the head of the spike 11 is retracted from the grounding surface of the tread 17 to run. When the vehicle is out of the designated area of prohibition and is on a snowy road, the head of the spike 11 can be projected and the vehicle can be driven, so that there is no need to worry about the legs of the vehicle.

Although the head of the spike 11 was retracted and ice and snow were suddenly encountered while traveling, a portion of the air in the large air chamber 22 was manipulated by operating the B valve 25 into a small tube even when the air injector was not carried. 7, the head of the spike 11 can be projected and used in a short period of time, so that the troublesomeness of the air injection work is relieved and the emergency measures can be taken in accordance with the road condition.

When traveling on a road without ice and snow, since the head of the spike 11 is retracted, the pavement surface is not scraped, so that no car dust is generated, human health is not harmed, and noise pollution is prevented. Is also useful.

Since the head of the spike 11 is retracted except when necessary, the marking objects such as lines, symbols, or letters by paint relating to road traffic are not scraped off, so that good paving surface can be maintained for a long time. This can save enormous road pavement costs and road marking repair costs.

If the snow-melting snow agent is sprayed on the paved road, the roadside trees will be adversely affected. Negative effects such as groundwater pollution and road surface damage are expected. Intermittent snowfall of 5 cm or more, and temperatures below zero 1
It is said that the effect of the snow-melting agent is weak when the temperature is lower than 0 degree. Therefore, if it is sprayed each time snowfall occurs, enormous road management costs are required. Therefore, the snow-melting agent is sprayed from the financial aspect of road management and environmental problems. It is very difficult to carry out the whole process, but it can be solved immediately by using the spike tire of the present invention.
