Description

[Detailed description of the invention] The present invention relates to an improvement of a two-stage suspension type spare tire holding device that can set small-diameter tires on the upper stage and large-diameter tires on the lower stage. Even with tires, we ensure the positioning of large and small tires to ensure that they do not slip and shift during lifting operations.
Alternatively, it is also possible to hold only small diameter tires.

In the conventional two-stage suspension type spare tire holding device that places a small diameter tire on top of a large diameter tire and holds it by lifting it,
As shown in FIG. 8, slipping occurs between the wheel disks B2' and A2' of the small diameter tire and the large diameter tire, resulting in poor retention.

This is because the lifting start position is generally set outward of the vehicle body from the tire holding position so that the tire can be easily set, and the vehicle is then pulled diagonally.

Therefore, the set tires become slippery.

For this purpose, as shown in Fig. 9, the cap supporter C provided at the wheel desk a' of the large diameter tire A is set so that it enters the air hole provided at the wheel desk a' of the small diameter tire B. It positions A and small diameter tire B and prevents them from slipping.

The cap supports C are protrusions for attaching caps of various designs to the wheel desk, and are provided in several numbers.

However, the above measures cannot be used for styled wheels in which the wheel disk does not have a cap supporter, for example, the wheel disk itself has various designs.

This invention can hold tires that do not have cap supports on the wheel desk, such as styled wheels, and prevents tires from shifting, and can also lift only large-diameter tires or only small-diameter tires. The object of the present invention is to provide a two-stage suspended spare tire holding device for a vehicle.

The invention will be described below with reference to the embodiments shown in the drawings.

First embodiment: As shown in FIGS. 1 to 5, a hanging plate 1 for positioning and lifting a large diameter tire A, and a spacer 2 for positioning between the large diameter tire A and the small diameter tire B.
It is made up of.

The hanging plate 1 has an elastic body 3 at its lower end, and its other end is attached to a hanging rod 5 fixed to a lifting chain 4.

(The above-mentioned lifting chains and hanging rods are called lifting devices.

) The suspension plate 1 has a bearing surface 11 formed longer than the diameter of the wheel desk hole A of the large-diameter tire A, and the bearing surface 1.
At least a pair of large-diameter tire positioning protrusions 6 are provided that project upward from the large-diameter tire A and abut on opposing surfaces of the inner peripheral surface 12 of the wheel desk hole A1 of the large-diameter tire A, respectively.

The spacer 2 includes a small-diameter tire mounting surface 13, an elongated central hole 10 through which the suspension plate 1 is inserted when lifting a tire in the center of the small-diameter tire mounting surface 13, and a small-diameter tire mounting surface 13. 13 and is formed on the wheel disk A2 of the large diameter tire A.
A downward outer flange 7 that comes into contact with the spacer 2 and becomes a positioning element for the spacer 2, and a projection insertion hole 9 into which the large-diameter tire positioning projection 6 of the hanging plate 2 is inserted when only the small-diameter tire B is lifted. It is provided between the edges 10a, 10b perpendicular to the longitudinal direction of the central hole 10 and the outer flange 7.

Further, the spacer 2 is formed with a flange 8 that projects upward from the periphery of the central hole 10 and serves as a small-diameter tire positioning protrusion that comes into contact with the inner circumferential surface 15 of the wheel desk β1 of the small-diameter tire B. .

However, the flanges 8 may be formed only on the longitudinally opposing edges 10c of the central hole 10, which are opposite to each other in the longitudinal direction.

In the above embodiment, two of the large diameter tire A and the small diameter tire B
When hanging one, place the spacer 2 on top of the large-diameter tire A, set the small-diameter tire B on the small-diameter tire mounting surface 13 of the spacer 2, insert the hanging plate 1 through the center hole 10 of the spacer 2, and then Pass the diameter tire A diagonally through the wheel desk U□,
Lift up the large diameter tire A from the bottom of the wheel desk A2.

If only the small-diameter tire B is to be hung, set the small-diameter tire B on the small-diameter tire mounting surface 13 of the spacer 2, and then
is inserted through the center hole 10 of the spacer 2, the large-diameter tire positioning projection 6 of the hanging plate 1 is inserted into the projection insertion hole 9 of the spacer 2, and the spacer 2 is lifted from the bottom side.

However, the shapes of the outer flange 7 of the spacer 2, the flange 8 serving as the small diameter tire positioning projection, the projection insertion hole 9, etc. are not limited to those in the embodiment.

Second embodiment: This is an embodiment shown in FIGS. 6 and 7. In this embodiment, the small diameter tire positioning protrusion is replaced with the flange 8 of the first embodiment, and the small diameter tire B has a hub bolt hole. 21 is provided with a pin 31 that is inserted into the hole.

As described above, the present invention can also be used for tires such as styled wheels in which the wheel disk is not provided with a cap supporter.

Furthermore, the downward outer flange provided on the spacer and the small-diameter tire positioning protrusion allow the large-diameter tire and the small-diameter tire to be positioned relative to each other, and this also prevents the tires from slipping and becoming misaligned.

In addition, the spacer and the suspension plate can be used as a single unit by inserting the large diameter tire positioning projection of the suspension plate into the projection insertion hole of the spacer, which has the effect of being able to lift even a small diameter tire alone. It is something.
