Description

  The present invention provides a gas introduction system into a tire and a tire puncture repair method when the tire is punctured.

  A conventional tire puncture repair system includes a sealing agent for repairing a punctured hole and a compressor for introducing air into the tire. However, the compressor is generally powered from a car cigarette lighter, and this repair system cannot be used if the writer socket is broken or the fuse is blown. .

  Further, Patent Document 1 discloses a method of filling the exhaust gas of an automobile as it is into a tire, but this is a method in which a hose is arranged between an exhaust pipe of an automobile and a tire valve, and a pressure is applied thereto. It is equipped with a regulating valve.

Japanese Utility Model Publication No. 59-109503

  However, the technique disclosed here is not necessarily safe in terms of its configuration, and is not a means used for repairing a tire puncture. In particular, exhaust gas from automobiles contains NOX components, which are considered to have an adverse effect on tires. For emergency treatment such as when the tire internal pressure is insufficient, this method is usually adopted. Absent.

  The present invention improves the above-mentioned drawbacks and provides a more complete tire gas introduction system and tire puncture repair method.

  A first aspect of the present invention is a system for introducing an automobile exhaust gas as a tire filling gas when a tire is punctured. The system includes an adapter for an automobile exhaust port and an adapter for a valve, which are connected to each other. A hose, a pressure relief safety valve and a pressure gauge are provided, and preferably a check valve is further provided.

  A second aspect of the present invention is a tire puncture repair method, in which a sealing agent is filled into a tire from a valve of a punctured tire, and then a gas is filled into the tire, and the tire is rotated to rotate the sealing agent. A tire puncture repair method for repairing a puncture by using a sealing agent mainly composed of rubber latex and using the in-tire gas introduction system of the first invention as a gas introduction system for filling a tire. It is a feature.

  In the first aspect of the present invention, a safer introduction system for exhaust gas from an automobile can be provided.

  Further, the second invention has an effect that the tire repair work is completed more safely and quickly.

  First, the first invention will be described. A system for guiding the exhaust gas of an automobile into a tire includes an adapter for an automobile exhaust port, a hose for guiding, an adapter for a tire valve, a safety valve, and an air gate. It is preferable to include a check valve on this.

  The material of the adapter to the exhaust port of the automobile is not particularly limited, but preferably rubber or plastic is preferable, preferably JIS-A hardness of about 40 to 98, more preferably about 60 to 80. is there. If it is 40 or less, it will be too soft and difficult to fit in the muffler, while if it is 98 or more, it will be too hard to insert. Further, as a fixing method to the muffler, it is preferable to tighten with a rubber-like hose belt or the like.

  The adapter to the tire valve is to be independent without twisting the hose when screwed into the tire valve, and the waste gas is ensured by pushing the worm in the tire when set in the valve. It is necessary to be. The material is not particularly limited, but is metal or plastic.

  The induction hose is preferably plastic, rubber, and those whose inner surfaces are reinforced with organic fibers or the like, and the shape of the induction hose is accordion to improve flexibility. The inside diameter of the hose is 15 to 100 mm, preferably 30 to 50 mm. If this is 15 mm or less, the ventilation resistance is too large and the engine is overloaded. On the other hand, when it is 100 mm or more, the storage property is deteriorated.

  The check valve is arranged in series with both valves in order to prevent the backflow of gas entering the tire, and an independent air chamber is secured. A pressure gauge is provided between the check valve and the tire valve. There will be di.

  The role of the safety valve is set because there is a possibility that the engine will be stopped or broken if the engine is overloaded when the system is used. The setting and pressure are preferably the appropriate internal pressure of the tire + 1 kg / cm2. For example, a safety valve of 3 kg / cm 2 is used in a car having an appropriate internal pressure of 2 kg / cm 2.

  The pressure gauge is used to check the safety valve in the tire. Normally, in order to check the tire internal pressure, it is necessary to stop the engine and display the pressure linked to the tire internal pressure. For this purpose, it is necessary to ensure an independent hermetic chamber with a valve. The gauge may be analog using a spring or digital, for example, but is preferably an analog type that can be used at a lower temperature.

  Next, the second invention will be described. A sealing agent is injected into a punctured tire through a valve. And after that, the exhaust gas of the automobile is filled in the tire, and the hole formed in the tire is closed by this sealing agent by running the automobile.

  The sealing agent in this repair system is, for example, one described in Patent Document 2 already proposed by the present applicant, the outline of which is only one of SBR latex, NBR latex, and a mixture of SBR latex and NBR latex. And a puncture sealing agent characterized by having a resin-based adhesive compatible with the rubber latex. Examples thereof include antifreezing agents, surfactants, dispersants, emulsifiers, and foam stabilizers. , PH adjusters, fillers and the like are added.

Japanese Patent Application No. 2003-135553

  Now, the rubber latex liquid as a sealing agent has a stabilizer and the like blended in the liquid, but the stability is lost by storage for a relatively long period of time, for example, the pH changes from the initial one. Aggregates are likely to occur. In particular, it is easily affected by the components in the air remaining in the container. For this reason, there are cases where the container is sealed together with an inert gas. When the rubber latex is agglomerated, it does not pass through the tire valve (3 mmφ), and the sealing agent cannot be filled into the tire.

  The present invention effectively utilizes this fact for tire repair. That is, exhaust gas exhausted from automobiles contains various components including NOX. Especially, NOX dissolves in the sealing agent, and the rubber latex component is easily aggregated by breaking the pH balance. As a result, the puncture repair time is shortened. In this way, the second invention takes the conventional idea in the opposite direction and quickly solidifies the rubber latex-based sealing agent filled in the tire to complete the puncture repair.

The following examples further illustrate the present invention.
(First invention)
FIG. 1 is a view showing an outline of an optimum example of a gas introduction system into a tire according to the first invention. 1 is an adapter to an exhaust port (muffler) b of an automobile a, and 2 is a valve d of a tire c. These adapters are connected by a hose 3 between them. And the pressure gauge 4 is provided in the adapter-2 side, and the non-return valve 5 is arrange | positioned on both sides of this. Further, the hose 3 is provided with a pressure relief safety valve 6. The automobile was 2000 cc, the total length of the hose 3 was 8 m, and the inner diameter was 4 cmφ.

(Second invention)
In the second invention, a sealing agent having the composition described in Patent Document 2 was used.

(Example 1 of the second invention)
The sealing agent was filled into a tire having a hole made by stepping on a 6 mmφ nail through a valve. After filling a predetermined amount, the above gas introduction system was used to fill the waste gas up to a tire pressure of 2 kg / cm 2 at an engine of 3000 rpm, and then the vehicle was run to repair the tire. The composition of the sealing agent is abbreviated in Table 1.

(Embodiment 2 of the second invention)
Similarly, the tire was repaired by changing the sealing agent. The composition of the sealing agent is abbreviated in Table 1.

(Comparative Example 1 of the second invention)
The same sealing agent as in Example 1 was used, but air was fed into the tire by a general-purpose compressor.

  Table 1 shows the seal properties of the tire together with the composition of the sealing agent.

  In Examples 1 and 2, the pH value of the sealing agent changes mainly due to the influence of NOX present in the exhaust gas filled in the tire, the rubber latex coagulates, and the tire puncture hole is clogged. -In the comparative example, the tire was filled with air (with very little NOx), so the adjusted pH value did not change much, and It has been found that a considerable mileage is required.

  In the present invention, a tire puncture repair system is realized by a combination of a rubber latex-based sealing agent and NOx-containing automobile waste gas, which is an extremely excellent system, and its operation is relatively It is simple and can be applied to all kinds of cars, and its utility value is high.
