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 attached to a spare tire supporting device provided in front of or behind the body.

As such a conventional spare tire supporting device, for example, one disclosed in Japanese Patent 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 mounted on a vehicle body, and a spare tire mounting bolt 5 is provided.
The bracket 53 is provided with a cover 53 having a hole through which 2 penetrates.
The first support wall 51a is provided via a spring 54. That is, the wheel 102 of the spare tire 101
Is pressed against the cover 53, the spare tire mounting bolt 52 protrudes into the hole of the wheel 102,
The spare tire 101 is supported by screwing the nut 55 onto the spare tire mounting bolt 52,
When 01 is removed, the cover 53 is pushed back by the spring 54 to cover the protruding spare tire mounting bolt 52. This prevents an obstacle caused by the spare tire mounting bolt 52 protruding from the protruding support wall 51a of the bracket 51 when the spare tire 101 is not mounted.

[0004]

However, in the one disclosed in JP-A-58-80379 as described above, the cover 53 pops out so as to cover the protruding spare tire mounting bolts 52, so that the spare tire is When 101 is not mounted, the entire spare tire supporting device becomes large, which not only spoils the appearance but also becomes very troublesome.

[0005]

In order to solve the above-mentioned problems, the present invention provides a hook that is installed in a base and is movably provided on the base so as to project from the base, and can swing on the base. And an arm for projecting the hook from the base, and a spring for moving the hook in a direction in which the hook is installed,
That is, the spare tire supporting device was constructed.

[0006]

In the spare tire supporting device having the above-described structure, when the arm is swung to project the hook biased to be installed in the base from the base, the spare tire is hooked on the hook and the hook is released. , Due to the weight of the spare tire, it stops in a state of protruding from the base. When you remove the spare tire from the hook, the hook will
It is installed in the base and there is no member protruding from the base.

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

As shown in these figures, mounting holes 1 are provided at the four corners.
An annular contact surface 1b that contacts the wheel 102 of the spare tire is formed on the front side of the plate-shaped base body 1 in which a is formed. Abutment surface 1
A plurality of bolt holes 1c are formed in b at predetermined positions. A communication hole 1d that connects the front surface and the back surface of the base main body 1 is formed in the central portion of the base main body 1.

A box-shaped base auxiliary portion 2 is provided on the back surface of the base body portion 1. Inside the base auxiliary portion 2, in the figure, on the lower side, a shaft 3 whose axis is oriented in a direction along a plane parallel to the contact surface 1b of the base body portion 1 is provided. It is supported by the base auxiliary portion 2 so as to be movable in a direction in which the front side and the back side of the base body portion 1 communicate with each other. Inside the base auxiliary portion 2, a hook 4 having a protruding shape is provided, and the base end side of the hook 4 is supported by the shaft 3. The tip side of the hook 4 penetrates through the communication hole 1d of the base body 1. A rubber material 5 is attached to the top surface of the hook 4 on the tip side.

That is, the hook 4 can be projected to the front side of the base body 1.

A shaft 6 is provided on the upper side of the inside of the base auxiliary portion 2 in the figure, with its axis facing the axial direction of the shaft 3. Engagement hole 4 formed in the upper surface of the base end side of the hook 4
The lower end side of the arm 7 is inserted into a. The middle of the arm 7 is swingably supported by the shaft 6. The upper end side of the arm 7 projects above the base body 1 and the base auxiliary portion 2.

That is, the arm 7 swings to cause the hook 4 inside the base auxiliary portion 2 to move.
It is made to protrude from the communication hole 1d of 1 or pulled into the inside of the base auxiliary portion 2.

A helix-shaped spring 8 is fitted on the shaft 6. One end side of the spring 8 is engaged with the base auxiliary portion 2 and the other end side thereof is engaged with the arm 7, and the spring 8 has the upper end side of the arm 7 protruding toward the front side of the base body 1. The arm 7 is biased so that

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

A weld nut 9 is provided on the rear surface side of the bolt hole 1c of the base body 1 so as to form the bolt hole 1c.
The bolt 10 inserted into is screwed.

It should be noted that the base body portion 1, the base auxiliary portion 2,
Thus, in this embodiment, the base is configured.

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 causes the hook 4 to communicate with the base body 1. It is projected from the hole 1d.
When the wheel 102 of the spare tire is hooked on the rubber material 5 of the protruding hook 4, the spare tire's own weight causes
The hook 4 stops in a protruding state and supports the spare tire. At this time, the rubber material 5 is the wheel 102 and the hook 4
Since the spare tire is prevented from sliding off the hook 4 due to the frictional resistance, the elastic force prevents the spare tire from contacting the wheel 102 or the worker with the hook 4 and being damaged. is there. Then, the bolt 10 is inserted from the hole of the wheel 102 and screwed into the weld nut 9, so that the spare tire is attached to 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 supporting device, the hook 4
Is moved into the base auxiliary portion 2 by the action of the spring 8.

As a result, not only the size of the spare tire supporting device when the spare tire is not mounted becomes smaller than that when the spare tire is mounted, but also the spare tire supporting device itself becomes smaller and the device structure becomes simple. Of.

In the present embodiment, the spiral spring 8 having one end engaged with the base auxiliary portion 2 and the other end engaged with the arm 7 is fitted to the shaft 6. Of spring 2
To the base body part 1 and the base auxiliary part 2
The hook 4 may be urged in the direction of moving into the base auxiliary portion 2 by engaging with the hook 4 and the other end side with the hook 4, or using a plate-shaped spring, By engaging one end side with the base body 1 or the base auxiliary part 2 and engaging the other end side with the hook 4 or the arm 7, the hook 4 is urged in the direction of moving into the base auxiliary part 2. 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 attached, and the hook is installed in the base by the spring when the spare tire is removed. The size when the spare tire is not attached is smaller than that when the spare tire is not attached, which not only improves aesthetics and safety but also simplifies the device configuration and makes it easy to attach and detach the spare tire.
