Abstract

PROBLEM TO BE SOLVED: To provide an emergency measure to make an automobile with a flat tire travelable into a safe repair place by taking emergency measures rapidly while suppressing labor to a minimum. SOLUTION: A tire gripping a solid tire around circular arcs with two large- small half moon shape obtained by cutting a circular thick plate at a straight line parallel to a diameter is used to attain a purpose. That is, the flat tire is left fitted, and the half moon shaped tire A1 is fitted and fixed as one of dual tires and then rotated by a half to place a segmented part topside, and the remaining half moon shaped tire B2 is fitted to form a complete circle so as to be travelable. Without using a jack, the divided temporary use tires are fitted at the dual tires over the flat tire without removing the flat tire so as to be temporarily travelable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique in which a jack can be used when an automobile is punctured, and an emergency tire can be attached to the vehicle so that the vehicle can travel quickly without removing the punctured tire. (Note: When expressed as a tire, it may mean the meaning of a normal tire and the wheel for automobiles including the tire.)

[0002]

2. Description of the Related Art In the case of a flat tire of a car, a spare tire is often replaced by a jack on a dangerous road, and a flat tire repair agent cannot deal with all flat tires.

[0003]

[PROBLEMS TO BE SOLVED BY THE INVENTION] It is to enable a punctured automobile to travel to a place where it can be repaired as quickly and safely as possible.

[0004]

[Means for Solving the Problems] Achieving the object by using a tire in which a solid tire is gripped around a circular arc with two large and small half-moon shapes of a circular thick plate cut by a straight line parallel to the diameter. You can That is, with the flat tires still attached, half-moon shaped tires are attached and fixed as compound wheels, and the latter half rotation is performed and the remaining half-moon shaped tires are attached with the missing circles facing up, making it possible to run in a perfect circle. .

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Of these two tires, assuming that the larger one is the emergency tire A and the smaller one is the emergency tire B, A is shown in FIG. 4 and B is shown in FIG. The structure of the tire itself is such that a rim having a C-shaped cross section is welded on an arc of a half-moon thick plate, and a solid tire is gripped and fixed to this. When these two are combined, as shown in FIG. 2, it becomes a complete circle, and A includes all mounting holes for the hub. The outer diameter, hole position, etc. are the same as the original tire. A counter weight 8 and a mounting guide plate 10 are mounted on A, and a mounting bracket 9 is mounted on B by welding. When B is attached to A, the attachment guide plate 10 is used as a guide to fit the attachment fittings and fixed with the fixing bolts 7 and 4. In the case of the emergency tire attachment, the spacer 6 is adjusted in height as shown in FIG. Save This is because the force for fastening and fixing the emergency tire is also applied to the ribs to stabilize the attachment.

[0006]

EXAMPLE When using this emergency tire, two methods A and B can be considered. The method A is the case of a normal original tire, and as shown in FIGS. 1 and 5A, the wheel nut of the tire having a flat tire is replaced with the long nut 3.
This is done while fixing each one. Next, the potato screw 5 is attached, then the spacer 6 is attached, and finally the emergency tire A is attached with the broken circle portion facing downward. In this state, the engine is started, the wheels are made to run a half turn, and as shown in FIG. 2, the vehicle can be run by mounting the emergency tire B with the chamfered circle portion facing upward.

Next, in the case of B, it is necessary to use the original tire 11 with a fixing nut shown in FIG. 9 (this tire is a utility model registration application filed on the same day as this application, reference number BA98-0509, flat tire). This is to apply a nut to the original tire wheel in advance by welding, crimping, or the like. The position is the central position of the wheel mounting hole position. In this case, as shown in FIG. 5 (b), it is not necessary to replace the long nut. Immediately after attaching the screw to the fixed nut, the fixed nut is fixed with the ordinary nut, and thereafter, the vehicle can travel in the same manner as the method A. This method requires a shorter processing time than A.

[0008]

The present invention is embodied in the form described above and has the following effects. There is no jack-up operation, and there is no need to put in or take out heavy spare tires.
It saves a lot of labor and the processing time is A according to the experiment.
In case of, it is 2 minutes. In case of B, it is 1 minute.

Claims (3)

[Claims] 1. A first-aid tire in which a solid tire is fixedly gripped on a circular arc with two large and small half-moon shapes obtained by cutting a circular thick plate by a straight line parallel to the diameter. 2. The emergency tire according to claim 1, wherein one of the two divided tires includes a total number of mounting holes to the hub. 3. The emergency tire according to claim 1, wherein when the emergency tire having a bisected shape is combined, the outer diameter, the position of the mounting hole to the hub, and the hole diameter are the same as those of the original tire.
