Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a spare tire storage device for a motor vehicle capable of storing either tempered tires or standard tires.

[Background technology]

In recent years, improvements in tire performance have drastically reduced the number of tire punctures, and wide tread tires have become popular as tires become flatter. Against this background, an increasing number of automobiles are equipped as standard with tempered tires (also called space saver tires), which require less storage space than standard tires.

Conventional spare tire storage devices are generally configured to place and fix a spare tire horizontally in a recess provided on the floor of a luggage room. In addition, in cars with sufficient depth in the luggage room, there is also a type that is fixed by leaning against the rear fender or the reinforcement on the inner surface of the rear fender. Furthermore, as improved and developed versions of these, Utility Model Application No. 57-50485,
There is a device proposed in Utility Model Application Publication No. 57-67878.

By the way, even in cars that are equipped with a tempered tire as a standard tire, there are some users who wish to use the standard tire as a spare tire. Furthermore, when using a tempered tire due to a tire puncture, the punctured standard tire must be stored. Many automobiles that come standard with conventional tempered tires are equipped with a separate storage device for the standard tires. Furthermore, many standard tire fixing means are of a type suitable for temporary storage. However, it is not desirable to have two types of storage devices that are not used simultaneously. Further, as described above, when a standard tire is to be kept on hand as a spare tire, it is not appropriate to use temporary fixing means.

The type of tire that is placed horizontally and fixed in the recess in the floor of the luggage room mentioned above can securely fix and store either a temporary tire or a standard tire. However, if this type of tire is adopted, the significance of having a temporary tire as standard equipment becomes very weak, and it cannot be applied to luggage rooms with a short depth.
As a device that can store any standard tire,
A device has been proposed in Japanese Utility Model Application Laid-Open Publication No. 58-58985. This device utilizes the space formed by the reinforcement on the inner surface of the fender and a recess in the floor surface to store the tempered tire upright and the standard tire at an incline. However, this device has a limit to the inclination angle of the standard tire, and the storage height of the standard tire cannot be significantly lowered. Therefore, the application is limited mainly to automobiles that have a luggage room at the rear of the vehicle body and the luggage room is relatively deep. Furthermore, since this device does not support the upper part of the tire at all when stored, it is thought that there is a problem (unstability) in fixing the standard tire, which is stored at an incline.

[Purpose of invention]

Taking the above facts into consideration, the present invention aims to provide a spare tire storage device that can be applied to a luggage room with insufficient depth and depth, and can stably store both tempered and standard tires. .

[Structure of the idea]

In the spare tire storage device according to the present invention, a clamp bracket having two female threaded holes each having a different orientation angle is fixed to the inner wall of the luggage room.
By arranging a support rod in the space above the bracket, the disk of the disk wheel can be stored, whether it is a tempered tire or a standard tire, which are supported by the sidewall abutting the support rod at different angles. By fastening the clamp plate that is fixed to the surface with one of the female threaded holes provided in the clamp bracket, it is possible to store any tire stably.

[Example of idea]

1 to 3 show a first embodiment of a spare tire storage device according to the present invention. In this embodiment, as shown in FIG. 1, the present invention is applied to an automobile having a luggage room at the front of the vehicle body which is insufficient in both depth and depth. Luggage room 1
0 is the end panel 12 at the front of the vehicle body, the bulk head 14 at the rear, and the side panels 16A and 16B at the side.
It is partitioned into a peripheral wall (not shown), a luggage pan 18 as a floor plate, and a hood 20.

As shown in detail in FIG. 2, the clamp bracket 22 is composed of a main body portion 22A bent in an inverted dogleg shape in the height direction and four mounting legs 22B. The main body part 22A has a female threaded hole 24A on the upper side of the bending part, and a female threaded hole 2 on the lower side.
4B is provided. The female threaded hole in this embodiment is not directly tapped into the main body, but is shown as an example in which square welding nuts 25A and 25B are welded.

As shown in FIG. 1, the clamp bracket 22 has upper, lower, left and right mounting legs 22B (only the upper and lower mounting legs are shown in FIG. 1) that are fixed to the lower wall 14A of the bulkhead 14 by welding. As shown in FIG. 1, the tempered tire 26 in its retracted state is held with its tread portion in contact with the luggage pan 18 and its sidewall portion in contact with the bulkhead lower wall 14A.

On the other hand, the upper part of the tire is held by the sidewall part coming into contact with a support rod 28 which is disposed horizontally in the left-right direction of the vehicle body in a space above the clamp bracket 22. In this way, the tempered tire 26 is held at the top and bottom and is placed in the luggage room 10 in a slightly inclined state.

The upper female screw hole 24A provided in the clamp bracket 22 has an angle and a height so that the center line coincides with the disk center line CL of the disk wheel (not shown) of the tempered tire 26 placed in the above state. is set. Standard tire 30
When the tire is retracted, as shown in
8 and is also held in contact with the end panel 12. In the upper part of the tire, as in the case of the tempered tire, the sidewall part is connected to the support rod 2.
It is held in contact with 8.

The lower female threaded hole 24B provided in the clamp bracket 22 has a center line that coincides with the disk center line CL of the disk wheel (not shown) of the standard tire 30, which is mounted in an inclined state relative to the tempered tire. The angle and height are set so that

Shown in FIG. 3 is the assembled clamp bolt 32 and clamp plate 34. The clamp bolt 32 includes a shaft portion 32A having a male threaded portion on one end side that engages with female threaded holes 24A and 24B provided in the clamp bracket;
Handle portion 32 fixed to the other end of the shaft portion
It consists of B. The clamp plate 34 has a clamp bolt 32 loosely fitted in the center part, and a lower tapered part 3.
4A is set so as to come into contact with the peripheral edge of the center hole of the disk portion of the disk wheel.

Next, the procedure for storing the spare tire in the device of this embodiment will be explained. When storing the tempered tire 26, the tempered tire 26 is placed in the state shown in FIG. 1, and then rolled left and right to bring the center of the disc wheel into approximately alignment with the female threaded hole 24A above the clamp bracket. Next, insert the clamp bolt 32 combined with the clamp plate 34 through the disc center hole of the disc wheel, and insert the male threaded portion at the tip into the female threaded hole 24.
Match with A.

Thereafter, the handle portion 32B is rotated to screw the two together and fasten them. Just before the completion of tightening, the clamp bolt is positioned at the center of the disc of the disc wheel due to the action of the tapered portion 34A of the clamp plate.
The tempered tire rolls slightly and aligns itself to the correct position. Also, when storing the standard tires 30, the first
After placing it in the state shown in the figure, the same procedure as above is performed.
Removal of any tire can be easily done by reversing the above steps.

In this way, in this embodiment, the lower part of both the tempered tire and the standard tire is held by the structural members of the luggage room, so there is an advantage that there is no need to provide a stopper or the like to hold the lower part. . Furthermore, since the lower sidewall of the tempered tire is held in surface contact with the lower wall of the bulkhead, it can be stored very stably and has the advantage that the luggage room can be used effectively. Furthermore, standard tires are stored at a large incline, so they can be stored even in narrow rat gauges, and are stable because they are supported above by support rods. Therefore, there is no sense of instability, and since the tire is stationary even before it is fastened, there is no need to support the tire with your hands during the fastening process. Furthermore, the presence of the support rod makes it possible to avoid contact between the piping 36, wiring, and tires. Note that if the lower part of the tire cannot be effectively held only by the luggage room constituent members, the present invention can be easily implemented by using a stopper member or the like.

A second embodiment of the invention is shown in FIGS. 4-6. This embodiment is an example applied to an automobile having a luggage room at the front of the vehicle body, similar to the embodiments described above. When a luggage room is provided in the front part of the vehicle body, as shown in FIG.
A brake master cylinder 38, a clutch master cylinder, etc. are disposed protruding from the inner bulkhead 14. In addition, in FIG. 5, the case of right-hand drive specification (solid line) and the case of left-hand drive specification (imaginary line) are illustrated at the same time. Therefore, in case
If the tires are poorly or not fastened at all, the tires may roll and come into contact with them. The present embodiment is configured to protect the brake master cylinder and the like even in such a case. That is, the difference from the above embodiment is that both ends of the support rod that come into contact with the tire sidewall portion are formed into a U-shaped support rod 40 with bent portions 40A that are bent across the tire tread portion. be. As a result, even if the tire rolls, contact with the brake master cylinder, clutch master cylinder, etc. can be avoided.

Note that since the master cylinder is disposed only on one side, right or left, depending on the change in the handle attachment position, the bent portion 40A of the support rod may be provided only on one side. However, by forming the handle in a U-shape as in this embodiment, it is possible to prevent the handle from rolling toward the side opposite to the master cylinder, and there is an advantage that there is no need to set the handle in the opposite direction depending on the specification of the handle.

Furthermore, a protection rod 42A is added to the support rod 40 of this embodiment.
Alternatively, by providing 42B, the master cylinder can be protected from other stored objects other than tires.

In both of the above embodiments, an example was shown in which the present invention was applied to a vehicle having a luggage room at the front of the vehicle body, such as a rear engine vehicle or a mid-ship engine vehicle, but it is also applicable to vehicles having a luggage room at the rear of the vehicle body.

As described above, in the embodiment of the present invention, even if the luggage space is narrow, the luggage space is not occupied by the tires when the tempered tires are stored, and the luggage space can be used effectively. Furthermore, standard tires can be reliably and easily stored using the same means as for storing tempered tires.
