DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare tire support device.

[0002]

2. Description of the Related Art In an off-road vehicle such as a four-wheel drive vehicle, a spare tire is often mounted on a spare tire supporting device provided in front of or behind a body.

[0003] As such a conventional spare tire support device, for example, one disclosed in Japanese Patent Application Laid-Open No. 58-80379 is known. As shown in FIGS. 5 and 6, a spare tire mounting bolt 52 is provided on a protruding support wall 51a of a bracket 51 having a U-shaped cross section which is mounted on a vehicle body.
The cover 53 having a hole through which the cover 2 is formed is attached to the bracket 5.
It is provided via a spring 54 on the side of the one protruding support wall 51a. That is, the wheel 102 of the spare tire 101
Is pressed against the cover 53, the spare tire mounting bolt 52 protrudes and enters the hole of the wheel 102,
The spare tire 101 is supported by screwing a nut 55 to the spare tire mounting bolt 52, and the spare tire 1
When the cover 01 is removed, the cover 53 is pushed back by the spring 54, and covers the protruding spare tire mounting bolt 52. This prevents an obstacle due to the projection of the spare tire mounting bolt 52 from the projecting support wall 51a of the bracket 51 when the spare tire 101 is not mounted.

[0004]

However, in the vehicle disclosed in Japanese Patent Application Laid-Open No. 58-80379, the cover 53 protrudes so as to cover the protruding bolt 52 for mounting the spare tire. When the spare tire 101 is not mounted, the entire spare tire support device becomes large, which not only deteriorates the appearance but also becomes very troublesome.

[0005]

A spare tire supporting device according to the present invention for solving the above-mentioned problems is provided with a hook which is mounted on a base and is movably provided on the base so as to protrude from the base. and the off is provided on the base so that it can swing to the projecting direction of the hook
An arm that causes the hook to protrude from the base in conjunction with the hook, and moves the hook in a direction in which the hook is housed, and moves the arm in the projecting direction of the hook.
A spring that urges the arm to swing.
When pressed by the spare tire,
And the hook is configured to protrude from the base.
It is characterized by having .

[0006]

In the spare tire support device having the above-described structure, when the arm is swung to project the hook urged to be installed in the base from the base, the spare tire is hooked on the hook, and the hook is Then, it stops with the spare tire protruding from the base due to its own weight. When the spare tire is removed from the hook, the hook is
There is no member protruding from the base because it is installed in the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a spare tire supporting device according to the present invention will be described with reference to FIGS. 1 is an external view, FIG. 2 is an exploded perspective view, FIG. 3 is a front view, and FIG. 4 is a side sectional view.

As shown in these figures, mounting holes 1 are provided at the four corners.
On the front side of the plate-shaped base body portion 1 formed with “a”, an annular contact surface 1b that contacts the wheel 102 of the spare tire is formed to protrude. Contact surface 1
In b, a plurality of bolt holes 1c are respectively formed at predetermined positions. A communication hole 1d is formed in a central portion of the base body 1 so as to communicate the front and back of the base body 1 with each other.

On the back of the base body 1, there is provided a box-shaped base auxiliary part 2. A shaft 3 whose axis is directed in a direction along a plane parallel to the contact surface 1b of the base main body 1 is provided below the inside of the base auxiliary portion 2 in the drawing. The base body 1 is supported by the base auxiliary unit 2 so as to be movable in a direction in which the front side and the back side of the base body 1 communicate with each other. A hook 4 having a protruding shape is provided inside the base auxiliary portion 2, and the base end of the hook 4 is supported by the shaft 3. The tip end of the hook 4 penetrates through the communication hole 1d of the base body 1. A rubber member 5 is attached to the upper surface on the tip side of the hook 4.

That is, the hook 4 can protrude toward the front side of the base body 1.

A shaft 6 is provided on the upper side of the inside of the base assisting portion 2 in the drawing, with the axis oriented in the axial direction of the shaft 3. An engagement hole 4 formed in the upper surface on the base end side of the hook 4
The lower end of the arm 7 is inserted into a. The center of the arm 7 is swingably supported by the shaft 6. The upper end side of the arm 7 protrudes above the base body 1 and the base auxiliary part 2.

In other words, the arm 7 swings, so that the hook 4 inside the base auxiliary portion 2 is attached to the base body portion 1.
Or through the communication hole 1d, or into the base auxiliary part 2.

A spiral spring 8 is fitted on the shaft 6. One end of the spring 8 is engaged with the base auxiliary part 2, the other end is engaged with the arm 7, and the upper end of the arm 7 projects toward the front side of the base body 1. The arm 7 is urged to perform the operation.

That is, the hook 4 is urged by the spring 8 so as to move to the inside of the base assisting portion 2.

A weld nut 9 is provided on the back side of the bolt hole 1c of the base body 1, and the bolt hole 1c
The bolt 10 inserted into the connector is screwed.

It should be noted that the base body 1, the base auxiliary unit 2,
Thus, in the present embodiment, a base is formed.

Such a spare tire support device is used as follows. The mounting tool 12 is inserted into the mounting hole 1a of the base body 1 and mounted on the body 11 of the vehicle. When the wheel 102 of the spare tire is brought into contact with the contact surface 1b of the base body 1, the upper end of the arm 7 is pushed by the wheel 102 of the spare tire, and the lower end of the arm 7 connects the hook 4 to the base body 1. Project from hole 1d.
When the wheel 102 of the spare tire is hung on the rubber material 5 of the protruding hook 4, the weight of the spare tire causes
The hook 4 stops in a protruding state and supports the spare tire. At this time, the rubber material 5 is attached to the wheel 102 and the hook 4
Not only prevents the spare tire from slipping off the hook 4 due to its frictional resistance, but also prevents the wheel 102 or an operator from being in contact with the hook 4 and being damaged by its elastic force. is there. Next, if the bolt 10 is inserted into the hole of the wheel 102 and screwed into the weld nut 9, the spare tire is mounted on the spare tire support device.

On the other hand, when the bolt 10 is removed and the spare tire is removed from the spare tire support device, the hook 4
Moves to the inside of the base auxiliary part 2 by the action of the spring 8.

Thus, not only is the size of the spare tire support device when the spare tire is not mounted smaller than when the spare tire is mounted, but also the spare tire support device itself is reduced, and the configuration of the device is simplified. It is.

In this embodiment, the spiral spring 8 whose one end is engaged with the base auxiliary portion 2 and the other end is engaged with the arm 7 is fitted to the shaft 6. Spring of axis 2
And one end of the base body 1 and the base assisting section 2
By engaging the other end with the hook 4, the hook 4 may be urged in a direction to move into the inside of the base auxiliary portion 2, or the plate spring may be used to One end of the hook 4 is engaged with the base body 1 and the base assisting portion 2, and the other end is engaged with the hook 4 and the arm 7. Is also good.

[0021]

As described above, in the spare tire supporting device according to the present invention, the hook projects from the base by the arm when the spare tire is mounted, and the hook is mounted on the base by the spring when the spare tire is removed. The size when the spare tire is not mounted is smaller than that when the spare tire is mounted, not only the aesthetics and safety are improved, but also the device configuration is simplified, and the attachment and detachment of the spare tire is simplified.
