Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor spare tire holding device for a vehicle, and more specifically, a standard tire having a wide tire width is used for normal running, and the standard tire becomes unusable due to a flat tire or the like. Sometimes, in a vehicle in which an emergency tire having a narrow tire width is used as the spare tire, each tire portion is mounted in the rear portion of the lower surface of the vehicle body floor and the standard tire or the emergency tire is tilted in the radial direction. The present invention relates to an improvement of an under-floor spare tire holding device for a vehicle, which is configured to be sandwiched and held in common.

[0002]

2. Description of the Related Art Generally, in the case of a vehicle in which a standard tire having a wide tire width is used for normal running and an emergency tire having a narrow tire width is used as a spare tire, the spare tire is stored and held. There are two types of underfloor spare tire holding devices to be installed at the rear of the underside of the vehicle body floor: one with the former standard tire storage standard and the other with the emergency tire storage standard. There are two types.

Since the standard tire and the emergency tire have a relatively large difference in tire width, the tires are stored in the underfloor spare tire holding device in a state in which the tires are tilted in the radial direction. Then, when it is held, the storage height inevitably has a difference in height.

Therefore, in the underfloor spare tire holding device in which the accommodation height is set high with reference to the storage of the standard tire, it is necessary to interpose a spacer or the like for compensating the height difference when storing the emergency tire. Therefore, when the original standard tire is stored in the underfloor spare tire holding device for the standard tire, an intervening spacer or the like is not necessary, and therefore the spacer or the like must be newly stored in the vehicle compartment. In addition, when there is a lot of cargo in the passenger compartment, the accommodation itself may be impossible, and even if the accommodation is possible, it is inevitable that it will be an obstacle.

Further, in the underfloor spare tire holding device in which the accommodation height is set low based on the storage of the emergency tire, even if the flat tire is to be stored, it cannot be stored because the height is too low to store it. There is a risk of damaging the standard tire.

Therefore, conventionally, there is provided a means for separately providing two types of underfloor spare tire holding devices for standard tires and emergency tires having different accommodation heights, or only an underfloor spare tire holding device for standard tires. After setting, the difference between the tire wheel shape of the standard tire and that of the emergency tire, that is, for the standard tire, the inner side of the inner surface is recessed correspondingly to the tire width compared to the outer surface of the outer surface when used. For emergency tires, on the other hand, it is necessary to secure the required wheel width, and by taking advantage of the difference that the back side is not recessed so much Only the under-floor spare tire holding device is set, and a pressing member replacing the spacer is projected from the lower surface of the vehicle body floor corresponding to the central portion of the setting portion, For tires, store them with the front design side facing down and with the recess on the back side avoiding the pressing member.For emergency tires, press the recess on the back side with the front side facing down. There has been proposed a means for storing by stopping with a stop member (see Japanese Utility Model Laid-Open No. 61-122987).

[0007]

However, each of the above-mentioned conventional under-floor spare tire holding devices for vehicles has the following problems.

That is, in the former means for providing two types of underfloor spare tire holding devices having different accommodation heights, the underfloor spare tire holding device for standard tires that can be used as both standard tires and emergency tires depending on the way of use. In accordance with the above, it is necessary to newly install an underfloor spare tire holding device for emergency tires, which is not always necessary, resulting in waste in configuration and use, and also leaves problems in terms of installation space, cost, etc. There was a disadvantage.

On the other hand, in the latter means for utilizing the difference in the tire wheel shape between the standard tire and the emergency tire, the standard tire or the emergency tire is stored in the apparatus, and the front side of the standard tire is stored. Since both the design surface and the front side of the emergency tire are held downward, these downward surfaces are liable to be damaged by pebbles or the like that are thrown up during running, and in particular they are essentially protected. It has an inconvenience that it is inevitable to damage the front side design surface of the standard tire, which is required.

Separately, various means for setting an underfloor spare tire holding device for standard tires and providing various operating mechanisms for storing the emergency tire to the device are also proposed (Actual No. 62-127082). However, in many cases, the actuating mechanism is not always effective and functional, and a good storage and holding action cannot be obtained.
The overall configuration also becomes relatively complicated and costly.

The present invention has been made to solve the above-mentioned conventional problems, and its object is to provide a standard tire and an emergency tire having different tire widths with a structure as simple as possible. Another object is to provide an under-floor spare tire holding device for a vehicle that can be stored and held in common.
