Description

[Detailed description of the invention] <Industrial application field> This invention is a tubeless tire puncture device in which a shaft-shaped cleaning tool and insert tool can be easily connected to or separated from the handle. It concerns repair tools.

<Conventional technology and its problems> To repair a punctured tubeless tire, the nail that had penetrated the tire was pulled out, the hole was shaped using a cleaning tool, and adhesive (vulcanized cement) was applied. The insert rubber is held between the tip of the insert tool and inserted into the hole.

By the way, such repairs are generally not easy for amateurs to carry out, so they are usually outsourced to a gas station or repair shop. In some cases, even amateurs will be required to perform repairs.

To do this, it is necessary to always have tools such as the cleaning tool in the vehicle, but the tools that have been commonly used in the past are, for example, a cleaning tool with a fixed handle a, as shown in Figure 4. b, a large handle c, a plurality of separable insert tools d, and other items such as insert rubber and adhesive were stored in a large tool box. Loading this item into a passenger car or truck is not a problem in terms of storage space, but if the vehicle does not have a spare tire and has limited storage space, such as a motorcycle, it is definitely necessary to keep it on hand. That was impossible.

Therefore, in order to solve the above-mentioned problems, the inventor of the present invention previously proposed a tubeless tire puncture repair tool in which a cleaning tool and an insert tool are detachably attached to the handle, and the handle is formed into a cylindrical shape. A tubeless tire puncture in which a cleaning tool, an insert tool, an adhesive, an insert rubber, etc. used for puncture repair are all stored in the cylindrical handle so that it can be stored compactly when carried. A repair tool has been developed which requires the cleaning tool or insert tool to be connected to or separated from the handle.

As mentioned above, there have conventionally been tools in which the insert tool can be connected to or separated from the handle, but the connection has been made using a screw e. Conventionally, the reason why the insert tool d can be connected to or separated from the handle using the screw e is to replace the type of the insert tool d, and from that purpose, it is easy to replace the insert tool d. It is clear that unless you can do that, you will not be able to achieve your goal. For example, if it is fixed by a screw e, a screwdriver is required to turn the screw e, and since the screw e is very small, it is complicated to handle.
In actual use, there were various problems.

<Means for solving the problem> Therefore, in order to solve the above problem, the tubeless tire puncture repair tool according to this invention has the following features:
In a tubeless tire puncture repair tool in which a cleaning tool and an insert tool are configured to be detachably attached to a handle, the handle is formed into a cylindrical shape, and a shaft hole is bored at a position facing each other in the middle part of the handle, A through-hole is drilled in a part of the shaft-shaped cleaning tool and insert tool.
Furthermore, the straight part of the stopper bar having a straight part, a curved part, and an L-shaped bent part is configured to be able to be inserted into and taken out from the through hole of the cleaning tool and the insert tool within the cylindrical handle, so that the stop bar has a straight part, a curved part, and an L-shaped bent part. The formed cleaning tool and insert tool can be easily connected to or separated from the handle.

<Embodiment> Next, an embodiment of the tubeless tire puncture repair tool according to this invention will be described based on FIGS. 1 to 3. 1 is a handle formed in a cylindrical shape, 2, Reference numeral 2' denotes a shaft hole bored in the middle part of the handle 1. Among these shaft holes, the shaft hole 2 is a perfectly circular shaft hole, and the shaft hole 2' is a shaft hole in which a concave portion 3 is formed in the diameter direction of a perfect circle. 4 has one end sharply formed,
It is a shaft-shaped cleaning tool with a file part 5 formed so as to be continuous with this, and when the other end of this cleaning tool 4 is inserted into the shaft holes 2, 2' of the handle 1, the shaft hole 2' A hole 8 for inserting a convex portion 6 and a stop bar 7, which will be described later, is formed so as to engage with the concave portion 3 of. Reference numeral 9 denotes an insert tool having a forked holding portion 10 at one end, and the other end of the insert tool 9 is formed with a convex portion 6' and a hole 8', similar to the cleaning tool 4. The stop bar 7 has a straight portion 11 and a curved portion 12.
and an L-shaped bent part 13, and at least the straight part 11 of this stop bar 7.
The diameter must be such that it can be inserted into the holes 8, 8' of the cleaning tool 4 and insert tool 9.

<Operation> When the cleaning tool 4 is attached to the handle 1, the base of the cleaning tool 4 is inserted from the shaft hole 2' side of the handle 1 until it reaches the other shaft hole 2. In this case cleaning tool 4
The shaft hole 2' is inserted so that the projection 6 of the shaft hole 2' is engaged with the recess 3 of the shaft hole 2'. Thereafter, the stopper bar 7 is inserted into the handle 1 from the side end of the handle 1, and then inserted into the hole 8 of the cleaning tool 4 and fixed. In this case, insert the straight part 11 of the stopper bar 7 into the hole 8 of the cleaning tool 4, and hold the stopper bar with the L-shaped bent part 13 so that the curved part 12 of the stopper bar 7 comes into contact with the inner wall surface of the handle 1. 7
is rotated and stopped when the L-shaped bent portion 13 becomes vertical. Then, this stop rod 7 uses the curved part 12 as a fulcrum and pulls the cleaning tool 4 in the direction of the shaft hole 2 by the straight part 11, thereby fixing the cleaning tool 4 to the handle 1. be. Therefore, the end of the cleaning tool 4 on the side that engages with the shaft hole 2 of the handle 1 is formed into a stepped shape (this also applies to the insert tool 8). When disassembling, the cleaning tool 4 is unfixed from the handle 1 by rotating the stopper bar 7, releasing the pressure of the curved portion 12 against the inner wall surface of the handle 1, and then pulling out the stopper bar 7. The cleaning tool 4 can then be removed from the handle 1. In addition, hold the insert tool 9 by the handle 1.
The same applies when fixing to or separating from.

<Effects of the invention> As described above, according to the tubeless tire puncture repair tool according to this invention, in the tubeless tire puncture repair tool in which the cleaning tool and the insert tool are configured to be detachably attached to the handle, the handle can be attached to the handle. In addition to forming the handle into a cylindrical shape, a shaft hole is bored in the middle part of the handle at opposing positions, and a through hole is bored in a part of the shaft-shaped cleaning tool and insert tool. The straight part of the stop bar, which has an L-shaped bent part, is configured to be inserted into and removed from the through hole of the cleaning tool and the insert tool within the cylindrical handle, so that the stop bar can be simply inserted and rotated. The cleaning tool or insert tool can be connected to or separated from the handle by simply turning the handle, and the effect is that connection and separation can be easily performed.
