Abstract

PURPOSE:To effectively repair a punctured tubeless tyre from the outside by urging a means which has a sleeve part engageably screwed on the external periphery of the end part of the drilling part which is attached to a tool at the end thereof, into the punctured part of a tyre from the outside before inserting from the outside a filler plug which has specific dimensions so as to be engaged in the sleeve part. CONSTITUTION:For repairment of a punctured tyre, a means which has a sleeve part 9 engageably screwed on a tool 8 having a drill part 7 at the end thereof is first urged into the punctured hole 6 on the tyre 5. The tool 8 is then removed but the sleeve part 9 only is left therein. A filler plug A is inserted in the central hollow part of the sleeve part 9 and squeezed into it from the rear part thereof by another tool 12 to which a push rod 11 is attached. The female screw part threaded on the tool 12 at the root part thereof and the male screw part 10 threaded on the sleeve part 9 at the end part thereof are screwingly engaged with each other and the plug A only is left in the punctured hole 6 by integrally pulling the sleeve part 9 and the tool 12. The stick-like main body 1 of the filler plug A having the shorter inner diameter than the sleeve part 9 has flanges 2 and 3 at both the top and bottom ends thereof and also has a core member 4 embedded through the center, said member 4 connecting the flanges 2 and 3 to each other.

As described in Japanese Patent No. 53701, there is a filler that uses a straight columnar body made of vulcanized rubber and an outer skin layer of a required width made of unvulcanized rubber formed on the outer periphery of the body. This method uses a tool with a male tip and a sheath screwed onto the outer periphery of the proximal end of the male part.This tool is inserted from the outside into the punctured part of the tire, and the tool is inserted into the punctured part of the tire. The elasticity of the tire is improved by unscrewing the screws, leaving only the sheath in the puncture hole, inserting the filling material into the sheath from outside the tire, and then pulling out the sheath and leaving the filler in the puncture hole. The puncture hole shrinks, and the outer skin layer of the filler is tightened and crimped on the fault plane of the puncture hole, and when the heat generated by the tire is added to this, vulcanization occurs, and the filler and tire are completely bonded. It is said that it is glued to.

、挿入が阻害されるという欠点もあった。Here, the columnar body of the filling material is formed to be thinner than the inner diameter of the sheath so that it can pass through the sheath without force, so it is best to repair it with the bank hole oriented horizontally. However, if repairs were made with the bank hole vertical, the filling material would fall into the tire, causing the repair to fail.Additionally, the unvulcanized rubber around the outside of the filling material was vulcanized. When the accelerator is applied and the filler is inserted into the sheath, the filler bends midway inside the sheath, causing friction between the unvulcanized rubber around the outer circumference of the filler and the inner wall surface of the sheath, causing the unvulcanized rubber to bend. Since the material is soft and easily sticky, its frictional heat causes it to adhere to the inner wall of the sheath, hindering insertion.

用できない。In addition, as a tire repair body, as described in Japanese Utility Model Publication No. 53-20322, a small-diameter umbrella is provided at one end of a rod-shaped body and a large-diameter umbrella at the other end, and the outer periphery of the rod-shaped body and It has been proposed that the inside of the large diameter umbrella is made of unvulcanized rubber. This repair body is used to repair the tire from the inside, and the large diameter umbrella is designed to fit tightly against the inner surface of the tire and become integrated with the tire, but it does not require the use of tools. It cannot be used for repair methods from outside the tire.

This eliminates adhesion to the inner wall surface of the sheath by preventing contact with the sheath.

また第２の従来技術に対しては、タイヤ外部からの修理
を可能としたものである。Furthermore, the second prior art allows repair from outside the tire.

The filling plug is characterized in that the filling plug is filled into the bank portion by using the filling plug, and the filling plug is located at the top and bottom of the rod-shaped body (11 and this rod-shaped body fl) whose diameter is smaller than the inner diameter of the sheath (9). Umbrella portions (21, +31 formed at the ends) and aggregate (
4), the outer diameter of the umbrella part (2), (31 is larger than the outer diameter of the rod-shaped main body (1) and slightly larger than the inner diameter of the sheath part (9) of the tool (8). Moreover, at least the surface layer of the rod-shaped main body (1) is made of unvulcanized rubber, and the other parts except for the aggregate (4) are made of vulcanized rubber.

以下、本発明を図面に示す実施例に基いて説明する。Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

It connects the rod-shaped body (11) and maintains the straightness between the umbrella part.In addition, the parts of the rod-shaped body (1) made of unvulcanized rubber are made of unvulcanized rubber, as shown in Figure 1. There are two cases: (part a) and a case where it is a surface part (part b) as shown in FIG.

) into the central cavity of the sheath (9), and push in the rear part with a tool (12) equipped with a push rod (11). The length of the push rod (11) is such that when it is pushed all the way into the sheath (9), the tip umbrella (2) of the plug (A) will slightly protrude from the tip of the sheath (9). After that, the female part at the base of the tool (12) and the male part 00 at the proximal end of the sheath part (9)
(see Figure 7), sheath (9) and tool (12)
If you pull out the plug (A) as one unit, only the plug (A) will be attached to the tire (5
) will remain in the bank hole (6) (see Figures 8 and 9). Although the drawing shows a state in which the umbrella part (2) at the tip of the plug protrudes into the inside of the tire, depending on the thickness of the tire, the umbrella part (2) will remain in the puncture hole (6). In this case, the extra portion (2) serves as a stopper to prevent the plug from being pulled out together with the sheath (9) inside the puncture hole, and the plug is reliably filled into the puncture hole (6). .
