Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle spare tire storage device.

[0002]

[Prior art]

 To prepare for a flat tire, a spare tire is installed in a spare tire storage device attached to the vehicle body. Among such spare tire storage devices, a storage device having a carrier pivotally attached to the vehicle exterior surface of the floor panel that constitutes the floor surface of the vehicle body can store the spare tire using the space below the floor panel. The advantage is that spare tires can be installed without reducing the space inside the vehicle.

In a conventional spare tire storage device of this type, a carrier is formed into a frame shape including pipes, one end side of which is pivotally attached to a vehicle panel floor outer surface of the vehicle body, and the other end side of which is fixed to the floor panel by bolts. The spare tire is sandwiched and held between the carrier and the floor panel.

In order to take out the stored spare tire, first, the bolt is turned to loosen the bolt, the carrier is released from the fixed state, and then the carrier is pivoted downward about the pivot portion side. In this way, the spare tire is freed, and then the tire is removed from the carrier. By performing the reverse operation, the tire can be stored in the vehicle body again.

As described above, since the spare tire can be stored in the space below the floor panel, it is possible to prevent the problem of narrowing the effective space in the vehicle interior.

However, in the conventional spare tire storage device of this type, since the carrier is made of a pipe, the stored spare tire is exposed to the outside. Therefore, when the vehicle is driven in this state, especially in rainy weather, the spattered water splashed up from the road directly hits the spare tire in which it is stored, and stains it. Further, when an automobile runs on a bad road, flying stones from the road surface may hit a spare tire and deteriorate the tire.

[0007]

[Problems to be solved by the device]

 An object of the present invention is to provide a spare tire storage device for an automobile, which eliminates the above-mentioned conventional drawbacks.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a protective case fixed to the vehicle panel outer surface of the floor panel, a tire storage box retractably housed in the case, and a direction in which the box is pulled into the protective case. We propose a spare tire storage device for a motor vehicle, which comprises a biasing means for biasing.

As can be seen from FIGS. 2 to 5, the spare tire storage device 5 in this example includes a protective case 6 integrally fixed to the vehicle exterior side surface of the floor panel 1 by bolts or welding (not shown). It has a tire storage box 7 housed in a case 6.

The tire storage box 7 is formed in a box shape with an open upper part, and a female screw member 8 is projectingly provided at the center thereof. The bolt 22 penetrates the central hole of the disc 10 of the spare tire 9 housed in the box 7 and the plate 21 placed on the upper portion of the disc 10, and the bolt 22 is screwed into the female screw member 8. The spare tire 9 is fixedly held immovably by wearing it and tightening it.

On the other hand, three axles 11 are rotatably supported at the bottom of the tire storage box 7, and wheels 12 are fixed to both ends of each axle 11. The three wheels 12 positioned on the left and right in FIG. 4 are respectively rotatably fitted on rails 13 fixed to both lower sides of the protective case 6.

FIG. 2 to FIG. 5 show a state in which the spare tire 9 is stored in the spare tire storage device 5. When the tire 9 is taken out, the vehicle is stopped and stored in the tire storage box 7. Grasp the attached handle 14 and pull it in the direction of arrow A, that is, in the rear side of the vehicle body 2. As a result, each wheel 12 rolls in the rail 13, and the tire storage box 7 moves to the rear of the vehicle body 2.

6 and 7 show a state in which the tire storage box 7 reaches the rearmost position. At this time, the tip of the box 7 is supported downward on the ground G. However, since the stopper projectingly provided on the storage box 7 and the mating stopper (both not shown) fixed to the floor panel 1 abut each other, the box 7 will not be completely separated from the protective case 6, and 6 and the position shown in FIG.

In this state, by loosening the bolt 22 and removing it from the female screw member 8, the spare tire 9 can be taken out from the storage box 7 (see FIG. 6).

As described above, the tire storage box 7 is accommodated in the protective case 6 so that it can be pulled out, and by pulling the box 7 to the rearmost position as shown in FIG. 6 and FIG. The spare tire 9 can be easily taken out from the. The spare tire 9 is stored in the storage box 7, the bolt 22 is screwed into the female screw member 8 to fix the tire 9, and the tire storage box 7 is moved to the storage position shown in FIGS. 2 to 5 again. Thus, the spare tire 9 can be stored.

In this way, the spare tire 9 can be taken out only by pulling out the tire storage box 7, and the work is extremely simple.

Further, as shown in FIGS. 2 to 5, when the spare tire 9 is stored, it can be stored under the floor panel 1 without any trouble, so that the space in the vehicle interior can be narrowed. There is no. Moreover, since the spare tire 9 can be stored inside the storage box 7 and the protective case 6, even if the vehicle is driven in this state, the muddy water and pebbles do not directly hit the spare tire 9 and the tire 9 It is possible to prevent contamination and deterioration of the.

By the way, in order to move the tire storage box 7 from the rearmost position shown in FIGS. 6 and 7 to the storage position shown in FIGS. 2 to 5, the box 7 is directed toward the inside of the protective case 6. Although it may be pushed in, the present embodiment is provided with a biasing means for biasing the tire storage box 7 into the protective case 6 so that the operation at this time can be performed easily. The details will be made clear below.

As shown in FIG. 5 and FIG. 8, a shaft 17 extending in the lateral direction of the vehicle body 2 is fixed to the inner side of the protective case 6, and an appropriate number of shafts, in the illustrated example, two shafts 17, are provided. A reel-shaped rotating body 18 is rotatably supported. As shown in FIG. 9, a spiral spring 19 is interposed between the rotating body 18 and the shaft 17, and the spring 19 is wound around the shaft 17, and each end of the spiral spring 19 is connected to the rotating body 18. It is locked to the shaft 17, respectively.
