BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height compensating structure for an anti-slip member mounted on a snow tire, and in particular, it can extend the service life and extend the period for exchanging a new anti-slip member. The present invention relates to a height compensation structure for a slip prevention member which is mounted on a snow tire and which can effectively utilize the slip prevention member and can be cost-effectively implemented.

2. Description of the Related Art In vehicles such as two-wheeled vehicles and four-wheeled vehicles, tires are used to support the load of the vehicle body, reduce the impact from the road surface, and transmit the driving force and the braking force to the road surface. Is installed. There are various types of tires that exhibit their functions depending on the road surface condition, steering condition, and the like.

For example, tires include radial tires having improved high-speed running characteristics and maneuverability, snow tires and spiked tires having improved snow running characteristics.

In the snow tire, the width of the tread is widened to increase the installation area, and the land of the tread compacts the snow and the groove forms a pattern for catching the snow, thereby improving braking performance and driving performance. In addition, on the snow tire, a slit is formed in the land part of the tread,
There is also one that improves running performance on snow by letting snow bite into this slit.

The spiked tire has a metal spike, which is an anti-slip member, driven into the land portion of the tread of the snow tire to enhance braking performance and driving performance on ice or completely frozen ice and snow.

[0006]

By the way, in recent years, due to problems such as road damage due to spikes and scattering of road constituent members scraped off by spikes, there has been a demand for an alternative to spiked tires. Therefore, in place of the metallic spike, a slip prevention member made of hard plastic, rubber, a wooden member, or the like has been proposed.

The anti-slip member is mounted on the slit of the snow tire. A snow tire equipped with this anti-slip member does not cause problems such as road damage or scattering of road components due to the nature of its material, and has braking and driving performance on ice or completely frozen ice and snow. Can be increased.

However, the anti-slip member made of the hard plastic, rubber, wood material or the like wears faster than the conventional metallic spikes. For this reason, the slip prevention member has a shorter service life than the metallic spike, and there is a disadvantage that the slip prevention member must be replaced with a new slip prevention member in a short period of time, resulting in high cost.

[0009]

SUMMARY OF THE INVENTION In order to solve such inconvenience, the present invention provides an anti-slip member to be installed in a slit of a snow tire, and compensates for a reduction in height due to wear of the anti-slip member. A feature is that a height compensating member is provided on the base side of the anti-slip member.

[0010]

According to the structure of the present invention, the height compensating member is provided on the base side of the anti-slip member to compensate for the reduction in height due to wear of the anti-slip member. The compensating member can compensate for the reduction in height of the anti-slip member due to wear.

Embodiments of the present invention will now be described with reference to the drawings.

1 to 7 show an embodiment of the present invention. 6 and 7, 2 is a snow tire, 4
Is the rim. In the snow tire 2, the carcass 6 is covered with a covering layer 8 made of rubber or the like, and the crown portion 10 is in contact with the road surface.
The crown portion 10 is provided with the side portion 14 continuous with the shoulder portion 12 and the bead portion 16 held by the rim 4 is provided.

In this snow tire 2, a bead wire 18 is internally provided in a bead portion 16 and attached to a rim 4.
A tube 20 is attached to the snow tire 2 so as to be inscribed in the carcass 6 and the rim 4, and retains air pressure.

A tread 22 is provided on the crown portion 10 of the snow tire 2. Tread 22
It comprises a groove portion 24 and a land portion 26. A slit 28 is formed in the land portion 26. This slit 28
Is to improve the running performance on snow by making the bite of snow.

As shown in FIGS. 1 and 2, the snow tire 2 is provided with an anti-slip member 30 fitted in the slit 28. The anti-slip member 30 is formed of a material such as hard plastic, rubber, or a wood member, and the tip 32 side is slightly projected from the land 26 and the base 34 side is positioned inside the slit 28 so that the slit 28 can be formed. It is installed.

The snow tire 2 has a slip prevention member 30.
A height compensating member 36 is provided for compensating for the reduction in height due to abrasion. The height compensating member 36 is interposed on the base portion 34 side of the slip prevention member 30 mounted in the slit 28.

Next, the operation will be described.

The snow tire 2 has slits 28 formed in the land portion 26 of the tread 22 as shown in FIGS. A slip prevention member 30 is attached to the slit 28.

As shown in FIG. 3, the anti-slip member 30 when mounted is in a non-wearing state, and the land portion 26 of the tread 22 is provided.
The tip portion 32 side is slightly projected from. The snow tire 2 equipped with this anti-slip member 30 does not cause problems such as road damage and scattering of road constituent members due to the nature of its material, and has braking performance and driving on ice or completely frozen ice and snow. Performance can be improved.

In the snow tire 2, as shown by the chain double-dashed line in FIG. 4, when the land portion 26 of the tread 22 is worn by running, the tip portion 32 side of the anti-slip member 30 is also worn.
The snow tire 2 in which the anti-slip member 30 is worn causes a decrease in braking performance and driving performance on ice or on completely frozen ice and snow.

In such a case, the worn anti-slip member 30 is removed from the slit 28. Anti-slip member 3
In the removed snow tire 2 of 0, the height compensating member 36 is mounted on the slit 28, and then the worn anti-slip member 30 is mounted on the slit 28 again.

As a result, the snow tire 2 is in a state in which the height compensating member 36 is provided on the base 34 side of the slip prevention member 30, as shown in FIG. As a result, the slip prevention member 30 can project a little from the land portion 26 of the tread 22 toward the tip portion 32, as in the non-wearing state.

As described above, the height compensating member 36 provided on the base 34 side of the anti-slip member 30 is provided to compensate for the reduction in height due to wear of the anti-slip member 30. The height compensating member 36 can compensate for the reduction in the height of the slip prevention member 30 due to wear.

By compensating for the reduction of the height of the anti-slip member 30 by the height compensating member 36, the service life of the anti-slip member 30 can be extended, and a new anti-slip member 30 can be obtained.
You can extend the period of exchanging with.

Therefore, the anti-slip member 30 can be effectively used, and the anti-slip member 30 having a reduced height can be used, so that the anti-slip member 30 can be cost-effectively implemented.

The anti-slip member 30 is formed in advance so that it can compensate for this height when the anti-slip member 30 is worn to a certain height. Further, the anti-slip member 30 may have various heights so that an appropriate height can be selected according to the wear state of the anti-slip member 30.

[0027]

As described above, according to the present invention, the height compensating member can compensate for the reduction of the height of the anti-slip member due to wear, the service life can be extended, and a new anti-slip member can be provided. You can extend the period of exchanging with. Therefore, the anti-slip member can be effectively used and can be cost-effectively implemented.
