[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare tire fixing device for an automobile.

0002

2. Description of the Related Art In recent years, a small-diameter tempered tire has been adopted in an automobile 1 as shown in FIG. 1 as a spare tire to be used only when a tire is punctured. FIG. 5 shows a conventional example of such a vehicle. As shown in the figure, conventionally, a shaft 33 of a spare tire holder 32 is inserted into an insertion hole of a spare tire (temper tire) 34 in a trunk room 31, and a threaded portion 35 at the tip of the shaft 33 is inserted into a spare tire bracket 34. Nut part 3
7, the spare tire holding portion 38 of the spare tire holder 32 is attached to the spare tire 3.
I was trying to keep it at 4. When using the standard tire 39 as a spare tire or temporarily storing it in case of a puncture, the temper tire 39
As with 4, it was decided to store and fix it.

[Problems to be Solved by the Invention] However, in the conventional spare tire fixing device, the spare tires 34, 39
are stored horizontally, and the rear space L of the trunk room 31 becomes larger to match the standard tires, which has the disadvantage that the living space becomes narrower in cars where the overall length is determined by a standard, such as a light car. In addition, when a car collides, the impact is applied to the horizontally placed spare tire 34,
39 and into the front living space 40, and the fuel tank also has the disadvantage of being easily damaged.

0004

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned circumstances, and includes a method of inserting the shaft of a spare tire holder into the insertion hole of the spare tire, and connecting the threaded portion at the tip of the shaft to the spare tire bracket. In the spare tire fixing device, the spare tire holding part of the spare tire holder holds the spare tire by screwing into the spare tire bracket, and the threaded part at the tip of the shaft is screwed into the spare tire bracket. Two threaded parts are provided, one threaded part for tempered tires is provided slightly inclined with respect to the horizontal plane, the threaded part for tempered tires is used when fixing the tempered tires, and the threaded part for standard tires is used for fixing the tempered tires. The threaded part for standard tires is provided at a greater angle than the threaded part for tempered tires, and is used when fixing standard tires, so that either tempered tires or standard tires can be fixed in the trunk room. The present invention provides a spare tire fixing device for an automobile.

[0005]

[Operation] In the present invention, both the tempered tire and the standard tire are fixed at an angle, so that in the event of a collision, it is difficult for the impact from the spare tire to be transmitted to the living space.
In addition, the cushioning function of the spare tire itself will be utilized. Furthermore, since the tires are fixed at an angle in this manner, less space is required than before, especially when using standard tires.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A spare tire fixing device for an automobile according to the present invention will be described below with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows an automobile 1 equipped with a spare tire fixing device according to the present invention. A spare tire fixing device according to the present invention is provided in a trunk room 2 of this automobile 1.

FIG. 2 shows an embodiment of the spare tire fixing device according to the present invention. In the figure, 3 is a spare tire holder, and 4 is a spare tire bracket. As shown in the figure, the spare tire holder 3 consists of a spare tire holding section 5 and a shaft 6, and the shaft 6 is provided with a threaded section 7 at its tip. The spare tire bracket 4 is fixed to the rear floor panel 8 of the trunk room 2, and has two nut parts (threaded parts) into which the threaded part 7 at the tip of the shaft 6 is threaded. One is a tempered tire nut part 9, which is inclined at an angle of about 17 degrees with respect to the horizontal plane. The other is a standard tire nut part 10,
It is provided at an angle of approximately 50°, which is larger than the tempered tire nut portion 9. In the figure, 8a is the cross member of the rear floor panel, 11 is the living space, and 1
2 is the partition panel, 13 is the back panel, 14
15 is the rear bumper and 15 is the trunk lid.

In the embodiment shown in FIG. 2, when fixing the small-diameter tempered tire 16, as shown in FIG.
Insert the shaft 6 of the spare tire holder 3 into 7,
The threaded portion 7 is screwed into the tempered tire nut portion 9. As a result, the tempered tire 16 is tilted at approximately 17 degrees and fixed by the spare tire holding section 5. On the other hand, when fixing a large-diameter standard tire 18, as shown in FIG.
Spare tire holder 3 in tire mounting bolt hole 19
The shaft 6 is inserted through the shaft 6, and the threaded portion 7 is screwed into the standard tire nut portion 10. As a result, the standard tire 18 is fixed in the trunk room 2 at an inclination of approximately 50°.

As described above, in this embodiment, both the tempered tire 16 and the standard tire 18 are fixed at an angle, so that in the event of a collision, the impact from the spare tire is difficult to be transmitted to the living space 11, and the fuel tank Damage to the spare tire can also be prevented, and the cushioning function of the spare tire itself can be utilized. Also, since it is fixed at an angle like this, it is especially suitable for large diameter standard tires.
The space L1 required when using 8 is smaller than the conventional one. Therefore, the living space 11 can be enlarged.

Although the above-mentioned tempered tire nut portion 9 was inclined at an angle of about 17° in the above embodiment, it can be set as appropriate depending on various design conditions, and is usually inclined at an angle of 15° to 2°.
Approximately 0° is suitable. In addition, although the inclination of the standard tire nut portion 10 was approximately 50° in the above embodiment,
This angle can also be set appropriately depending on various design conditions, and is usually preferably about 40° to 55°.

0012

[Effects of the Invention] According to the present invention, a single spare tire bracket can be used to fix either a temper tire or a standard tire, and can be fixed at an angle. As a result, it is possible to save space in the trunk room, reduce damage to the fuel tank in the event of a collision, and soften the impact, which has great effects.
