BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The tire 2 has a front side surface 2, a tread portion 3, a rear side surface 4, a wheel 4, and a tire cover 6. Tire cover 6
Is a circular sheet in a developed state that can be formed into a cylindrical shape surrounding a front side surface 2, a tread portion 3, and a back side surface 4 of the tire 1 and formed of a heat-shrinkable resin film such as PVC or polyethylene. The aperture member 8 is formed on the sheet-like member 7, and a squeezing member 8 is attached to the periphery of the sheet-like member 7 so as to squeeze the periphery of the sheet-like member 7, and the end is exposed. Although the squeezing member 8 of the embodiment is a string-shaped member, a method may be employed in which a hook provided on an elastic string-shaped member used when attaching a chain is locked to the peripheral edge of the sheet-shaped member 7.

In the embodiment, the sheet-like member 7 is
It is formed in a size that surrounds one tire 1,
A plurality of tires 1 may be arranged in a cylindrical shape and formed to have a size surrounding the tires. At normal temperature (before mounting), the tire cover 6 is formed of a heat-shrinkable film material made of a flexible synthetic resin, and is configured to deform when temporarily fixed to the outer periphery of the tire 1. Heat shrinkage rate of about 30 to 60% by high temperature hot water or hot air of about 70 degrees or more, does not fuse with the tire 1 during heat shrinkage, and after shrinkage, at room temperature, 260 kg / cm ² or more It is configured to have tensile strength.

Further, the coloring material can be easily colored by mixing a coloring material into the raw material before being formed into the sheet member 7. In the figure,
9 is a perforation provided on the peripheral edge of the sheet-like member 7,
When using the tire 1, the tire cover 6 is peeled off from this portion.

[0009]

Next, the operation will be described. The tire cover 6 is made of a flexible synthetic resin heat-shrinkable film material at room temperature (before mounting), and is a sheet-shaped member having a size surrounding the front side surface 2, the tread portion 3, and the back side surface 4 of the tire 1. 7, the sheet-like member 7 is rolled or folded and packed for transportation, sale, and the like. Thus, in the tire cover 6, the sheet-like member 7 is applied to the front side surface 2, the peripheral edge of the sheet-like member 7 is folded toward the tread portion 3, and then the peripheral edge of the sheet-like member 7 is And the sheet-like member 7 is turned around so that the peripheral edge of the sheet-like member 7 contacts the side surface of the back side surface 4, and is temporarily fixed.

Next, hot water or hot air is applied from the outer periphery of the sheet member 7 to thermally shrink the sheet member 7.
The sheet-like member 7 surrounds the front side surface 2, the tread portion 3, and the back side surface 4 of the tire 1, becomes the tire cover 6, and cuts the end of the squeezing member 8 to complete the mounting. In this case, if a coloring material is mixed into the raw material before being formed into the sheet-shaped member 7, coloring is possible, and the added value of the product is improved.

Although not shown, a seal or the like is attached to a portion of the tire cover 6 surrounding the front side surface 2 and the tread portion 3 (not shown) to improve the added value of the product. Since the sheet-like member 7 shrinks, the pattern and the like are deformed, so that a sticking means such as a seal is effective.

When the tire 1 is used, the tire cover 6 is partially cut off with a cutting tool such as a pinch or cutter, and then peeled off. In this case, if the strength of the tire cover 6 at the portion where the squeezing member 8 is sewn is made lower than that of the squeezing member 8, the tire cover 6 can be partially cut by the squeezing member 8, Easy peeling.

[0013]

According to the present invention, the front side surface 2 of the tire 1 is made of a flexible heat-shrinkable resin film such as PVC or polyethylene.
And a circular sheet-like member 7 that can be cylindrical and surrounds the tread portion 3 and the back side surface 4, and a squeezing member 8 for narrowing the periphery of the sheet-like member 7 is attached to the periphery of the sheet-like member 7. Since the tire cover is a tire cover of any size, the tire cover can be mounted simply by heat shrinking, no matter how large the size of the tire. By selecting the heat-shrinkable film, the structure is simple, the manufacturing cost is low, the storage and transportation before mounting is easy, the cost can be reduced, and the coloring material is mixed with the raw material before forming into the sheet-like member 7. Since it can be easily colored, a color combination such as matching with the color of the vehicle body can be easily made, and the added value of the product can be improved. Since the present invention is a tire cover configured to be thermally contracted by hot water having a temperature of 70 ° C. or higher or hot air, the mounting operation can be greatly facilitated. In the present invention, a sheet-like member 7 formed in a circular shape from a heat-shrinkable resin film of polyethylene having flexibility is applied to the front side surface 2 of the tire 1, and the tread portion 3 of the tire 1 is positioned on the back side surface 4 side. The sheet member 7 is folded, and the peripheral edge of the sheet member 7 is narrowed down by squeezing the squeezing member 8 provided on the outer peripheral edge to position the sheet member 7 on the side surface of the back side surface 4. It is a method of mounting a tire cover that is attached by heat shrinking it, so mounting of the tire cover is completed simply by heat shrinking any size tire, and mounting work is extremely difficult It is easy to use, and by selecting a heat shrink film of polyethylene for the material of the tire cover, the structure is simple, the manufacturing cost is low, the storage and transportation before mounting is easy, the cost can be reduced, and the sheet-shaped part Since the coloring material can be easily mixed by mixing a coloring material into the raw material before forming into 7, the color combination such as matching the color of the vehicle body can be easily performed, and the added value of the product can be improved. .
