Description

[Detailed Description of the Invention] The present invention relates to a tire wrench that also serves as a jack handle, which is a tool used when replacing tires of automobiles, etc.

Conventionally, when changing a car tire, a pantograph jack was installed at a predetermined location on the bottom of the car body.
I turned the jack handle to raise the car, and then used a tire wrench to install and remove the hub nuts. However, in this case, the pantograph jack,
It is inconvenient because you have to prepare three tools: a jack handle and a tire wrench, and
Temporary tightening and loosening of hub nuts when installing and removing tires must be done by hand, which is troublesome.

The present invention has been made in view of the problems of the prior art described above, and provides a jack that reduces the number of preparation tools needed when changing a tire and also allows temporary tightening and loosening of hub nuts when installing or removing a tire. The purpose of this invention is to provide a tire wrench that also serves as a handle.

For this reason, the configuration of the tire wrench with jack handle of the present invention is such that a socket portion is provided at the tip of the rod portion on one side of the bending rod bent in an L-shape to fit into the wheel hub nut from the axial direction of the rod portion. With,
The rod member is connected with a pin to the end of the rod portion on the other side of the bending rod so that it can swing within the same plane as the rod portion provided with the socket.

A rotary pipe is provided at this joint portion to restrict the swinging of the rod member and release the restriction,
A pantograph engaging portion that engages with a pantograph jack is provided at the tip of the rod member.

With this configuration, when the rod member is bent with respect to a rod portion that does not have a socket portion of the bending rod, it becomes a jack handle, and the rod member is positioned coaxially with respect to the rod portion. It is characterized in that it can be used as a tire wrench when it is used.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 indicates a bent rod bent into an L-shape. A wheel (not shown) is attached to the end of the rod portion 13, which is one side of the L-shape of the bending rod 1.
A socket portion 2 is provided which is fitted into a hub nut (not shown) from the axial direction of the rod portion. Reference numeral 3 designates a rotary pipe attached to a rod portion 13 provided with a socket portion 2.

On the other hand, the base end 9 of a rod member 8 is joined to the end 4 of the rod portion 13, which is the other side of the L-shape of the bent portion 1, with a pin 10, and the rod member 8 is provided with the socket portion 2. It is designed to be able to swing within the same plane as the rod portion 13. Further, a pantograph engaging portion 7 that engages with a pantograph jack (not shown) is provided at the tip of the rod member 8.

Reference numeral 11 denotes a rotating pipe, which is attached near the joint of the pin 10 so as to restrict the swinging of the rod member 8 and release the restriction. In addition, the rod member 8
The distal end is tapered to facilitate removal of the wheel cap (not shown), and furthermore, a rotating pipe 11 is attached near the base end 9. Reference numerals 5 and 12 indicate bulges that serve as stoppers to stop the rotation pipe 11 from moving.

Now, when the rod member 8 extends at right angles to the rod portion 13 of the bending rod 1 that does not have the socket portion 2 as shown in FIG. 1 and is bent around the pin 10, the bending rod 1 This tool consisting of the rod member 8 and the rod member 8 serves as a jack handle. That is, by engaging the pantograph engaging portion 7 with the pantograph jack, gripping the rotary pipe 11 with the left hand, and gripping and rotating the rotary pipe 3 with the right hand, the jack is activated and the vehicle body can be moved up and down. When performing this lifting and lowering operation, it is not always easy to operate the jack handle depending on the installation position of the jack with respect to the automobile and the conditions such as the road surface. In such a case, since the joint by the pin 10 can freely swing, the operating position of the jack handle can be adjusted to suit the situation, resulting in good workability. Also,
When the rod member 8 is positioned coaxially with the rod portion 13 as shown in FIG. 2, this tool becomes a tire wrench. That is, the hub nut can be attached and detached by fitting the socket portion 2 to the hub nut, grasping the rotary pipe 3 with the left hand, and grasping and turning the rod member 8 at an appropriate position. When temporarily tightening or loosening a hub nut, use this tool as shown in Figure 1 to fit the socket part 2 to the hub nut, grip the rotating pipe 3 with your left hand, and grip the rotating pipe 11 with your right hand. This can be done by turning. However, temporary tightening and loosening of the hub nut is done in the condition shown in Figure 1.
If the rotary pipe 3 is gripped with the left hand, the right hand does not necessarily have to grip the rotary pipe 11, and may be gripped at an appropriate position on the rod member 8. Further, the temporary tightening and loosening of the hub nut may be carried out by fitting the socket portion 2 to the hub nut in the state shown in FIG. 2, and grasping the rod member 8 at an appropriate position. In short, when temporarily tightening or loosening the hub nut, since the rotary pipe 3 is rotatably loosely fitted to the bending rod 1, there is almost no load on the left hand, so do not temporarily tighten or loosen the hub nut directly by hand. in,
This can be done with this tool.

In this tool, if the state shown in FIG. 1 and the state shown in FIG. The bulges 5 and 12, which function as stoppers, are unnecessary. However, if the bulges 5 and 12 as in this embodiment and the rotating pipe 11 which also serves as a locking sleeve as shown in FIG. 2 are used,
The states shown in FIGS. 1 and 2 can be reliably obtained with an extremely simple structure, and it is easier to hold the rotary pipe 11 by hand than to hold the rod member 8 directly by hand when using it as a jack handle. Of course, if you grip it with the latter, the load on your hand will be less.

As described above, according to the present invention, a socket portion is provided at the tip of one rod portion of the bent rod bent in an L shape so as to fit into a hub nut from the axial direction of the rod portion, and the other rod portion A rod member is provided at the tip of the rod so that it can swing in the same plane as the rod portion provided with the socket portion, so it can be used as a jack handle, a handle for temporarily tightening or loosening hub nuts, and a tire wrench. In addition to being able to provide functions, the bending rod functions as a handle when temporarily tightening jack handles and hub nuts, and has excellent operability. The number of tools required when changing a tire can be reduced, and the temporary tightening and loosening of hub nuts can also be done with a tool.Furthermore, by integrating two tools, the weight and cost of the tire changing tool can be reduced. We can provide a tire wrench that can also be used as a handle to reduce the amount of jitter.
