Abstract

A pneumatic vehicle tire is provided to damage the external appearance of the tire by easily removing engaging studs formed in a sidewall, a tread and a rim cushion section from the tire. A pneumatic vehicle tire comprises a tread(1), a sidewall(2) and a bead section(3). A plurality of engaging studs(4) are formed at the end portions of the sidewall and the tread and the outer side of a rim cushion section(31). The engaging stud is provided with a locking stud(41). The engaging stud has a section of an arrow or a mushroom such that decorations are easily engaged with the engaging stud. The engaging stud comprises material identical to that of a part at which the engaging stud is formed. The decorations have at least one engaging hole corresponding to the engaging stud.

The present invention adds a decorative function to a pneumatic tire for a vehicle.

Recently, it is common to express various personalities on a vehicle. Nevertheless, vehicle tires have been excluded from the field of personality expression. The tread pattern part, which can express various designs, is hard to recognize from the outside because it is touched on the ground or hidden inside the body, and thus does not have a visual effect.

Looking at the prior art for solving this problem, as shown in Figure 1, the technique of forming a stud hole 102 at a predetermined interval in the tire sidewall 101 site (published number 94-26517) bar have. However, this technique has the following problems.

1) Forming the stud hole 102 in the sidewall 101 may reduce the durability of the sidewall. In particular, since the sidewall is a site of severe flexion movement, the stress is concentrated in the stud hole may cause cracks.

2) The stud hole may be deformed due to the flexing movement of the sidewall part while driving, which may cause the combined decoration to detach.

3) The decoration may be detached due to damage of the stud hole inlet part while the tire is running.

4) Increasing the size of the head of the decorative joint to strengthen the binding force may cause cracks in the tire during the fitting process.

5) According to the tire flexion movement, the decorative head exerts periodic pressure on the sidewall rubber, which may damage the sidewall rubber.

6) Since the sidewall of a tire is generally thin in rubber, there are limited areas where stud holes can be made. In particular, in the case of PCR tires, it is difficult to make the stud hole in various locations because of extremely limited areas.

7) In order to make stud holes, the thickness of the rubber should be thick, which leads to an increase in tire weight.

8) The appearance is not good without the decoration.

9) If it is not attached, it is easy to open and foreign substances can be inserted.

10) In mold processing, there is a fear of workability and mold durability deterioration because the projection with the head portion must be formed on the inner surface of the mold.

11) It is difficult to make a light, thin and soft material because the ornament must fit into the stud hole. As the weight of the decoration increases, the risk of being separated by the high-speed rotation of the tire increases.

Accordingly, the present invention forms a plurality of engaging projections having engaging jaws on the sidewalls, the distal end of the tread, and the outer side of the rim cushion portion, thereby allowing the vehicle to stably decorate the tire without deteriorating the rigidity of the tire. The purpose is to provide a mouth tire.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is composed of a tread (1), a sidewall (2) and a bead portion (3), the sidewall (2), the distal end of the tread (1) and the outer surface of the rim cushion portion (31) Characterized by forming a plurality of engaging projections 4 having a jaw (41).

As shown in FIG. 4, it is preferable to form coupling protrusions on the sidewalls, the distal end of the tread, and the rim cushion portion so that the user can attach the ornament to the desired position. After attaching the ornament, the engaging projection 4 to which the ornament is not attached can be easily removed with a cutter or scissors.

Coupling projection (4) is preferably the shape of the head portion is larger than the body portion in order to have a coupling jaw (41). For example, it is preferable that the cross-sectional shape as shown in FIG. 1 is arrow shape or mushroom shape. Arrow shape or mushroom shape has the advantage of easy fitting of the decoration because the width of the end is narrow.

The coupling protrusions 4 respectively formed on the sidewall 2, the distal end of the tread 1, and the rim cushion portion 31 are preferably made of the same material as that of the portion corresponding to the formed position. This has the advantage of forming a coupling protrusion in the mold to form a coupling protrusion without additional process in the vulcanization process of the green tire by forming a groove.

3 is a cross-sectional view of any ornament 5 attached to a vehicle tire of the present invention. The decoration 5 includes one or more coupling holes 51 corresponding to the coupling protrusions 41. Ornaments are not limited to the material, but light weight is preferred.

As described above, according to the present invention, it is possible to stably attach decorations (brands, certification marks, photographs, shapes, etc.) to the tires without deteriorating the rigidity of the tires, thereby enabling various individual expressions. In addition, the sidewall, the end of the tread and the rim cushion portion do not touch the ground, so it does not significantly affect the noise problem, and the engaging protrusion can be easily removed, so that the tire aesthetics of the tire are not damaged even without the decoration. In the manufacturing process, there is an advantage that does not significantly reduce the durability of the mold because it does not form a relatively weak protrusion on the mold.

Claims (2)

A pneumatic tire for a vehicle, comprising a tread, a sidewall, and a bead, wherein a plurality of engaging projections having engaging jaws are formed on the outer surfaces of the sidewall, the distal end of the tread, and the rim cushion portion. 2. The pneumatic tire for a vehicle according to claim 1, wherein the engaging projections (4) respectively formed on the sidewall, the distal end of the tread, and the rim cushion portion are made of the same material as the corresponding portions.
