Description

[Detailed Description of the Invention] This invention relates to a spare tire storage device for an automobile.

Conventionally, cars are equipped with a spare tire that has the same diameter and width as the driving tire (normal tire), and when the driving tire becomes flat, the driver takes out the spare tire and replaces it with the flat tire. In addition to using a flat tire, it was common for the car to be equipped as a spare tire after the flat tire was repaired.

However, in recent years, various efforts have been made to reduce the weight of automobiles in order to improve fuel efficiency, and tempered tires, which have a smaller diameter, narrower width, and lighter weight than normal tires, have come to be used as spare tires. In other words, these tempered tires are not used regularly for driving, but are used temporarily until a flat tire is repaired.
Therefore, after a puncture in a normal tire is repaired, the repaired normal tire is immediately replaced with a temporarily used tempered tire.

By the way, the conventional spare tire storage device for a van-type vehicle is designed to sandwich the spare tire between the vehicle body and a tire hanger whose ends are pivotally attached to the underside of the vehicle body, and to lock the tire hanger to the vehicle body. It is designed to store a spare tire. Therefore, in order to equip a van type vehicle with a tempered tire as described above as a spare tire, it is necessary to make such a storage device capable of storing both tempered tires and normal tires.
The structure became complicated and the cost inevitably increased.

Therefore, we installed a storage device exclusively for tempered tires.
Some van-type vehicles are designed to store flat tires in the luggage compartment, but in such van-type vehicles, the tire may not be able to be stored when the luggage compartment is loaded, and it is also difficult to store the tire in the luggage compartment. Sometimes the cargo compartment would get dirty and the tires would fly off while driving, which was very inconvenient.

In order to solve this problem, it is conceivable to separately provide a spare tire storage device exclusively for normal tires, but in this case as well, there is a problem that there is not much suitable installation space and the cost is high.

This idea was devised in view of the above-mentioned conventional problems. A mounting frame for placing tires is provided between the rods on both sides of a tire hanger that is pivotally connected to the vehicle body. To provide a very convenient spare tire storage device for an automobile that can store both tempered tires and normal tires by making it possible to store tempered tires in an upright state and normal tires in a laid down state. The purpose is

An embodiment of the present invention will be described below with reference to the drawings.
