Description

[Detailed Description of the Invention] This invention relates to an improvement in the storage structure of a spare tire for a vehicle.

Generally, a storage space H for a spare tire S is formed by recessing a floor panel P that constitutes a trunk room T of a vehicle body.

Then, the spare tire S is placed in the storage section H formed in this way.
Conventionally, the device for storing and fixing the
9-121245 and Utility Model Application Publication No. 54-13161, but to explain this, as shown in FIG. A well-known device is a device in which a threaded rod 4 is used to fix a fixing member 3 to a fixing fitting 3 disposed coaxially with a hub hole 2 formed in a hub hole 2 .

This fixing metal fitting 3 has an insertion hole for a threaded rod 4 at approximately the center thereof, and a nut 5 coaxially with this insertion hole on the back side.
is welded to the spare tire S by rotating and tightening the screw rod 4 inserted through the screw hole 8 of the wheel holding fitting 7 fitted into the hub hole 2 made in the task 1 of the spare tile wheel 6. is firmly fixed and held within the storage section H.

However, in such a conventional spare tire fixing device, the wheel holding fitting 7 must be fitted into the hub hole 2 made in the wheel 1, and the threaded rod 4 must be inserted one by one to secure the spare tire. Not only is the work of storing or removing S complicated, but if the outer diameter of the hub hole fitting part of the wheel holding bracket 7 does not match the inner diameter of the hub hole 2, it is necessary to use a spare to prevent vertical movement due to vehicle body vibration. Even if it is possible to hold the tire S in the storage part H, it is likely to be misaligned due to longitudinal and lateral movement, and as a result, the hub hole 2
However, there are many problems such as the tendency to become a so-called idiot, and improvement of this problem has been strongly desired.

In addition, as a storage method for the spare tire S, in addition to using the hub hole 2 of the spare tire S as described above, the tread surface of the spare tire S is pressed and the spare tire S is held elastically between the opposite side wall of the storage section. There are also known methods for
1746).

However, all of these methods have problems in that the structure is complicated and the number of parts increases, and the work for storing and removing the spare tire S is complicated.

This idea was devised in view of the current situation, and
The purpose of this is to arrange at least one or more leaf springs protruding inward of the storage part on the circumferential wall of the spare tire storage part, and to use this spring material to press the tread surface of the spare tire against the surrounding wall of the storage part. The purpose of the present invention is to provide a spare tire storage structure for a vehicle in which the spare tire is supported between a leaf spring and the peripheral wall of the storage area, thereby simplifying the work of storing or removing the spare tire. be.

This invention will be described in detail below based on embodiments shown in the accompanying drawings.

As shown in FIG. 2, the spare tire S according to this embodiment
The storage portion H is formed to have a slightly larger diameter than the outer diameter of the spare tire S, and a leaf spring 10 is fixed to the peripheral wall of this storage portion H.

As shown in FIG. 3, this leaf spring 10 has a side surface bent into a substantially fishhook shape, and an upper end rising portion 11 serving as a base is welded and fixed to the peripheral wall of the storage portion H.

A sloped part 14 that slopes downward from the upper end rising part 11 as a base, and a tread surface pressing part 12 that extends downward from this sloped part 14 and presses the tread surface of the spare tire are oriented toward the center direction X of the storage part H. is given an elastic force, and the lower part of the tread surface pressing portion 12 is bent in the direction of the circumferential wall of the storage portion H to form an unclamper 13.

Therefore, when storing the spare tire S in the storage part H according to this embodiment, the spare tire S is press-fitted from above the storage part H against the elastic force of the leaf spring 10.

At this time, an elastic force from the tread surface pressing portion 12 of the leaf spring 10 in the direction X of the hub hole 2 of the spare tire wheel 1 acts on the leaf spring contact tread surface S1 of the spare tire S. 2, the tread surface S2 on the opposite side to the tread surface S1 is strongly pressed against the peripheral wall opposite to the peripheral wall of the storage section H to which the leaf spring 10 is fixed, and the spare tire S is pushed in the direction of X in FIG. will be supported by.

At this time, the spare tire is guided by the inclined portion 14 of the leaf spring 10 and is easily stored in the spare tire storage section.

When the spare tire is stowed, the leaf spring 1
Since the unclamper 13 of No. 0 maintains some clearance from the peripheral wall of the spare tire storage section, the spare tire can be easily removed by pushing the unclamper 13.

Further, the lower end of the tread surface pressing portion 12 of the leaf spring 10 is curved to form an unclamper 13, so that when the spare tire is removed, the lower end of the tread surface pressing portion 12 of the leaf spring 10 is caught on the spare tire. Nothing happens.

In the above embodiment, m leaf springs 10 are stored in the storage section H.
Although the case where the leaf springs are fixed to the peripheral wall is shown as an example, this invention is not limited to the number of leaf springs, and for example, two or more leaf springs may be arranged to further strengthen the resilient state of the spare tire S. You can also do that.

As mentioned above, this idea is based on the fact that a leaf spring with an elastic force is placed in the storage part that stores the spare tire toward the center of the storage part, thereby fixing the spare tire to the leaf spring. Because it is elastically supported between the surrounding wall on the opposite side of the storage area, the number of parts can be greatly reduced compared to conventional spare tire fixing devices that require wheel holding brackets and rods. Not only is it possible to fix and remove the spare tire extremely easily, but also the spare tire will not fall out of the storage space due to the vertical movement of the vehicle body vibration, as well as the longitudinal and horizontal movement. It has many beneficial effects.
