DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare tire storage device for an automobile.

[0002]

2. Description of the Related Art Generally, a spare tire carrier for an emergency tire placed under the floor can accommodate only one kind of tire width dimension, and cannot store a standard tire.

[0003] In recent years, Japanese Patent Application Laid-Open No. Hei 1-301475 discloses that the width of a tire to be stored is adjusted according to the width of the tire.
It has been proposed that the front end of the carrier can be moved up and down so that tires having different widths can be stored.

As shown in FIG. 3, a carrier 1 for mounting a tire on the rear lower surface of a floor panel 100 of a vehicle body.
01 is provided, and the tire is sandwiched and held between the lower surface side of the floor panel 100 and the carrier 101 from above and below, and one end of a wire 102 is connected to the front end of the carrier 101. The other end of this wire extends toward the rear end of the vehicle body, and the front end of the carrier 101 is
A guide hole 10 is provided between the upper and lower pivot holes 103a and 103b.
3c and the carrier 101
The carrier 101 is rotatable up and down around a front end of the carrier. In the drawing, reference numeral 104 denotes a lock rod for locking the rear end of the carrier 101, and its length is adjusted by screwing a bolt 105.

According to this, a tire having a small width is engaged by engaging the front end of the carrier 101 with the upper pivot hole 103a, and a tire having a large width is engaged by engaging the front end of the carrier 101 with the lower pivot hole 103b. Can be stored respectively,
Two types of tires having different width dimensions can be selectively stored.

[0006]

However, the storage device has a structure in which the front end of the carrier 101 is displaced up and down by the pushing and pulling operation of the wire 102, so that the structure becomes complicated and the cost is increased. In addition, there is a problem that the reliability of the device is low.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive spare tire storage device having a simple structure and high reliability.

[0008]

A spare tire storage device according to the present invention comprises a carrier support member attached to a rear lower surface of a floor panel, and a front end portion of the carrier support member.
A tire carrier pivotally supported via a link and capable of being displaced in the vertical direction, a stopper for fixing the tire carrier at a predetermined position in the vertical direction, and a rear lower surface of the floor panel
The rear end of the tire carrier is
A lock rod having a lock portion, wherein the link has one end thereof.
The other end of the carrier support member is connected to the tire carrier.
Pin-coupled and below the carrier support member
And the carrier support member from the same position
Pivots around the joint point of, and contacts the stopper,
Rotate to the position to displace the tire carrier more upward
The locking rod can be located behind the floor panel.
Lower with the degree of screwing into the nut supported on the lower surface
The vertical position of the end hook is configured to be adjustable .

In addition, it is preferable to provide an urging means for urging the tire carrier so as to always move the tire carrier upward, even if the width of the tire is slightly different at the time of storage when the stopper mechanism does not act, which is preferable.

[0010]

According to the above construction, the height of the tire carrier can be changed by the link mechanism, and the structure can be simplified.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a spare tire storage device according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a side view of the present apparatus, and FIG. 2 is a perspective view of a main part thereof.

As shown in the figure, a pair of left and right carrier support members 3 each composed of an L-shaped arm is hung down from a cross member 2 located on the rear lower surface of a floor panel 1 of a vehicle body. The tire carrier 5 having a lattice frame shape is connected.

That is, one end of the link 4 is connected to the tip of the carrier support member 3 with the pin 6, and the other end of the link 4 is connected to the front end of the tire carrier 5 with the pin 7.
In the present embodiment, a torsion coil spring 8 is wound around the pin 6 and constantly urges the link 4 to rotate counterclockwise in the figure.

A stopper rod 9 is provided between the left and right bent portions of the carrier support member 3 so that the link 4 comes into contact with the stopper rod 9 to restrict the counterclockwise rotation. Has become.

On the other hand, the rear end of the tire carrier 5
The tire carrier 5 on which the tire A is mounted is held in a horizontal state by being locked by the lock rod 10.

The lock rod 10 is constituted by a hook bolt with a stopper 10b penetrating the cross member 11 up and down, and the vertical position of the hook portion 10a can be adjusted by the degree of screwing into the nut 12 welded to the cross member 11. It has become. 13 in the figure is a spacer,
It is detached when storing a small width tire such as an emergency tire.

With such a configuration, when storing a tire A having a large width such as a standard tire, the tire carrier 5 is placed in a solid line in FIG. 1 and the space between the floor panel 1 and the tire carrier 5 is stored. Should be expanded.

At this time, the fine adjustment due to the slight difference in the width dimension is performed by the upward biasing force of the torsion coil spring 8 at the front end of the tire carrier 5 and by the locking force at the rear end of the tire carrier 5. It can be adjusted by the degree of screwing of the rod 10.

On the other hand, when storing a tire A having a small width such as an emergency tire, the tire carrier 5 is detached from the hook 10a of the lock rod 10 from the state of the solid line in FIG.
The link 4 at the front end of the tire carrier 5 may be rotated in a counterclockwise direction by, for example, pushing the rear end of the tire carrier 5 forward and then pushing it upward.

As a result, the link 4 eventually comes into contact with the stopper rod 9 and is prevented from rotating, so that the tire carrier 5 is in the state of the imaginary line in FIG. 1, and the space between the floor panel 1 and the tire carrier 5 is reduced. Narrowed. After that, the rear end of the tire carrier 5 has the locking rod 10 with the spacer 13 removed.
May be locked to the hook portion 10a.

In the above embodiment, the stopper mechanism is not limited to the stopper rod 9 in the illustrated example, but may be provided on the link 4 itself or another link mechanism itself with a different structure.

[0022]

As described above, according to the present invention, the carrier support member attached to the rear lower surface of the floor panel, and the front end portion is pivotally supported by the carrier support member via the link mechanism so as to extend in the vertical direction. A tire carrier capable of displacing the tire carrier, and a stopper mechanism for fixing the tire carrier at a predetermined position in the vertical direction, and operating the rear end of the tire carrier to move the tire carrier up and down, thereby reducing the width of the tire carrier. Since it is configured to be able to hold different tires, it is possible to provide an inexpensive spare tire storage device with a simple structure and high reliability for the device.
