Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to improvements in tire repair tools.

[Conventional technology]

Currently, tubeless tires are popular as tires for passenger cars and other vehicles.

If air leaks occur in tubeless tires,
One repair method is to insert a rubber plug into the leak and use the tire's own elastic contraction force to close the leak.

To load the above-mentioned plug, a rocker equipped with a piercing needle along the central axis is driven into the leak hole of the tire with a hammer, etc., the piercing needle is pulled out, and the plug is inserted through the hole using a pressure gun. Press fit. There are two types of pressure guns: one into which a rubber plug is directly inserted, and the other into which the plug is pushed in with a continuous press-fitting spanner.

However, since the tire is an elastic body and has high internal pressure, a large repulsive force is generated when driving the rocker, and frictional resistance is also large, so driving the rocker and plug described above is troublesome, and if performed by an inexperienced person, the tire may be damaged. It is not uncommon for it to be damaged.

Furthermore, the pressure gun is a fairly expensive piece of equipment and is not something that ordinary people, other than tire specialty shops and repair shops, have on hand.

[Problem that the invention attempts to solve]

The present invention was developed to solve the above problems, and the purpose is to provide a tubeless tire repair tool that can be easily used by the vehicle owner, making it easy to puncture the tire and fill it with repair agent. The purpose of the present invention is to provide an inexpensive and small-sized tire repair tool.

[Means for solving problems]

The above purpose is to carve a screw on the outer periphery of a sharp drilling rod with a grip handle at one end, and also to make a pair of grooves or chamfers along almost the entire length in the longitudinal direction, and to set the tire at an appropriate position. This can be achieved by a tire repair tool that is provided with a notch for retaining the repair agent.

[Effect]

With the above configuration, when the tip of the piercing rod is applied to the leak hole of the tire and the grip handle is rotated, the piercing rod is screwed into the leak hole by the screw formed on the outer periphery of the piercing rod, At the same time, the repair agent attached to the notch of the drilling rod is also fed into the leak. After that, when you pull out the punching rod from the tire by holding the grip handle, the repair agent remains inside the leak hole of the tire and the elastic force of the tire is added to completely block the leak hole, making it easy to complete the repair work. be. [Example] Hereinafter, the details of the present invention will be specifically explained with reference to an example shown in the drawings.

Fig. 1 is a perspective view showing an embodiment of the tire repair tool according to the present invention, and Fig. 2 shows the tire repair tool shown in Fig. 1 with a repair agent attached and applied to the leak hole of the tire. FIG. 3 is an explanatory diagram showing a state where the tire repair tool is pulled out from the tire.

In the figure, 10 is a grip handle, 11 is a drilling rod,
12 is a screw formed on the outer periphery of the punching rod; 13 is a diagonal notch for attaching a repair agent formed at approximately the midpoint in the longitudinal direction of the punching rod; 14 is a mounting integrally formed with the grip handle 10; Bosses 15 and 16 are curved gripping parts of the grip handle 10, 17 and 18 are a pair of grooves or chamfers formed over substantially the entire length in the longitudinal direction of the punching rod 11, 24 is a repair agent, and 25 and 25 are the bosses. At both ends, 26 is a bent portion of the repair agent 24, and 40 is a tire.

The grip handle 10 has a mounting boss 14 provided at its center.
The gripping portions 15, 1 are integrally molded with the
6 is rounded and curved for easy grip. A conically pointed drilling rod 11 is firmly fixed to the mounting boss 14, and a screw 12 is attached to the outer periphery of the drilling rod 11.
is formed.

The screw 12 is chamfered along the longitudinal direction of the drilling rod, so that the outer periphery of the drilling rod 11 has a chamfer in the longitudinal direction at least from the notch 13 to the tip. A guide path is formed along which the tire repair agent remains.

Further, a notch 13 for mounting a repair agent 24 is formed at approximately the middle position in the longitudinal direction of the punching rod 11.

When using the tire repair tool, attach a piece of repair agent 24 made of adhesive synthetic resin to the notch 13, and apply the tip of the punching rod 11 to the leak hole of the tire. When the grip handle is rotated, the drilling rod is screwed into the leak hole by the screw formed on the outer periphery of the drilling rod (see Fig. 2), and at the same time, the repair agent 24 attached to the diagonal notch is screwed into the hole.
is also sent into the leak. At this time, the drilling rod 1
1 is screwed in sufficiently, both ends 25, 25 of the repair agent 24 are pressed against the outer circumferential surface of the tire at the tip of the mounting boss 14, and the bent portion 26 of the repair agent reaches the inner space of the tire, and the repair agent 24 reaches the inner space of the tire. The entire leakage hole is filled with repair agent 24. After that, the above grip handle 1
0 and pull out the punching rod 11 from the tire.
Since the side surface of the drilling rod is chamfered along its longitudinal direction, the repair agent is not removed by the screw, and only the drilling rod 11 can be pulled out smoothly, and the entire repair agent 24 is absorbed into the tire. (See Figure 3). Depending on the type of repair agent or the way it is attached to the notch 13, if the repair agent comes out together with the drilling rod, hold down both ends 25, 25 of the repair agent 24 with appropriate stoppers while holding the drilling rod 11. By pulling it out, only the repair agent is left inside the leak. In such a case, the repair agent inside the leak is crushed by the elastic contraction force of the tire, thereby completely closing the leak and completing the repair work.

As described above, by using the tire repair tool according to the present invention, it is possible to repair a tire leak hole in a single operation, and it is also possible to repair a leak hole in a tire in one operation, and also to prevent the repair agent from getting into the tire too much, or from leaving the tire together with the punching rod. To do so, even an ordinary person can perform tire repair work efficiently and without damaging the tire without being drawn out.

[Effect of idea]

Since the present invention is constructed as described above, it is possible to provide an inexpensive and small-sized tire repair tool for repairing tubeless tires that can be easily used by the vehicle owner himself. .

The configuration of the present invention is not limited to the embodiments described above, but includes all embodiments that can be easily deduced by a person skilled in the art from the above description within the scope of the purpose of the present invention. be.
