Description

[Detailed Description of the Invention] This invention relates to a spare tire holding device for an automobile.

A holder is provided on the underside of a car body to store a spare tire horizontally, with one end of the holder rotatably pivoted to the underside of the car body, and the other end of the holder supported in a manner that can be freely engaged and detached from the underside of the car body. There is something I tried to do.

3 and 4 show the structure of a conventional example of a support mechanism for the other end of the holder, the details of which are as follows.

A holder 2 for storing the spare tire 1 horizontally is located on the rear lower surface of the vehicle body 3, that is, on the rear floor 4.
It is located on the lower surface of the vehicle and in front of the rear bumper 5. The front end 2a of the holder 2 is pivotally connected to a support fitting 7 fixed to a cross member 6 of the floor 4.

In addition, a guide bar 8 is fixed to the center of the holder 2 so as to be perpendicular to the guide bar 8, and the rising portions 8a at both ends of the guide bar 8 hold down both sides of the spare tire 1 placed thereon to prevent it from moving in the vehicle width direction. It is set as.

The rear end 2b of the holder 2 is attached to the rear edge of the vehicle body 3.
A mechanism is provided to support the lever in a freely engaging and disengaging manner.

That is, a bolt 10 is provided so as to pass through the rear end 4a of the floor 4 and the cross member 9 fixed thereto and hang down, and the head 10a of the bolt 10 is positioned on the upper surface of the floor 4. There is.

Hook 1 that engages and supports rear end 2b of holder 2
A nut 12 is welded to 1, and the nut 12 is screwed into the threaded portion 10b of the bolt 10, and the hook 11 is attached.
is connected to bolt 10. The rod portion 10c of the bolt 0 appearing between the cross member 9 and the hook 11 is covered with a space cylinder 13 made of rubber.

In order to remove the rear end 2b of the holder 2 from the hook 11, the head 10a of the bolt 10 is rotated with a tool, and the nut 12 engages the threaded portion 10c of the bolt 10.
The hook 11 moves downward along the arrow .

However, since the bolt 10 and the hook 11 are always located in a straight line, unless the bolt 10 is tilted to the 10' position and the hook 11 is moved to the 11' position, the rear end 2b of the holder 2 will Hook 1
I can't deviate from 1.

Since the bolt 10 and the hook 11 are placed in an inclined state, the shape of the bumper 5 located at the rear must be changed to avoid collision, and a considerable gap must be provided between the bumper 5 and the bolt 10 or the hook 11. This causes problems in that bumper design becomes difficult and affects the design of the vehicle body.

Further, the space cylinder 13 made of a rubber material is used to seal so that rainwater and mud do not enter inside through the insertion hole 9a of the cross member 9 through which the bolt 10 is inserted. Therefore, it is necessary to make the insertion hole 9a large and long, which results in a problem that the sealing performance is insufficient.

The present invention was devised to solve these problems, and is constructed as follows.

In other words, the hook that supports the other end of the holder,
It is connected via a nut pin attached to its upper end to a bolt fitted and hanging down from a cross member on the underside of the vehicle body, and the hook is moved up and down by rotation of this bolt. The hook is rotated around a rod portion extending on both sides of the nut pin, so that the other end of the holder can be easily and reliably engaged with and removed from the hook.

5 to 9 show the structure of an embodiment of the present invention, and the differences from the structure of the conventional example described above are as follows.

That is, the bolt 10 is provided so as to penetrate through the rear end portion 4a of the floor 4 and the cross member 9, and to be fitted and suspended, and its head 10a is positioned on the upper surface of the floor 4.

A hook 14 and a nut pin 15 are provided to engage and support the rear end portion 2b of the holder 2, and the threaded portion 15a of the nut pin 15 is connected to the threaded portion 10 of the bolt 10.
The support part 1 is provided at the upper end of the hook 14 with a rod part 15b screwed into the screw part 15b and extending from the threaded part 15a to both sides.
4a so that the hook 14 can freely rotate around the rod portion 15b to a position 14'.

Further, the rod portion 10c of the bolt 10 appearing between the cross member 9 and the nut pin 15 is fitted with a space tube 16 made of rubber material to cover it.

In order to remove the rear end 2b of the holder 2 from the hook 14, the head 10a of the bolt 10 is rotated using a tool, and the nut pin 15 engages the threaded portion 1 of the bolt 10.
0b, and the hook 14 is lowered. Then, attach the hook 14 to the rod part 1 of the nut pin 15.
If you rotate it around 5b to the 14' position,
The lock between the hook 14 and the rear end portion 2b of the holder 2 is released.

In this way, the rear end 2b of the holder 2 can be opened. At this time, the bolt 10 only moves up and down vertically and does not need to be tilted as in the conventional example, so the bumper 5 is attached to the rear end 2b. It can be freely designed without considering the support mechanism.

Also, since the bolt 10 is not tilted, the bolt 1
There is no need to make a large hole 9a for the cross member 9 into which the cross member 9 is inserted, and sealing performance is sufficiently maintained by the space cylinder 16, so that rainwater and mud do not enter into the cross member 9.

And since the bolt 10 is not tilted, it can be reliably tightened perpendicular to the bolt seating surface.
Also, since the bolt insertion hole 9a is not made large,
In addition, the hook 14 does not reduce the strength of the car body.
Since the bolt 10 is rotated backward, the removal work from the holder 2 is facilitated, and even if an installation error occurs in the setting position between the bolt 10 and the rear end portion 2b of the holder, this can be easily absorbed. I can do it. Moreover, since the bumper 5 does not interfere with the hook 14, rust will not develop due to contact scratches.

The present invention allows the holder for holding the spare tire to be easily and reliably engaged and disengaged, and has many advantages as described above, and is highly effective in practice.
