Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pneumatic tire, and more specifically, a brand name and a size are printed on the outer circumferential surface of the tire.

This invention relates to improvements to pneumatic tires that display various marks and precautions for use using display media such as letters or figures.

[Conventional technology]

The brand name, size, various marks, precautions for use, etc. are displayed on the outer circumferential surface of the tire.

[Problem that the invention seeks to solve]

However, rubber products such as tires are entirely black because carbon black is used as a reinforcing agent, and even if the above characters or figures are displayed on the surface, unlike other products, they are not visible. It's hard to get caught.

° In this regard, when displaying text, for example, it is usually bordered with thin ridges or grooves, or a collection of many thin ridges running parallel to each other, as shown in U.S. Pat. No. 4,198,774. It is known that characters are displayed in physical form.

However, the former is difficult to read and has a small display effect because it is simply a framework of ridges or grooves on a surface of the same color.Although the latter is superior to the former in terms of display effect, it is especially suitable for passenger car tires. Nowadays, where fascination is required along with tread patterns, it is unavoidable that the display becomes monotonous, and furthermore, the many thin grooves that make up the letters and between the edges are clogged with dust and dirt. Easy to do. As a result, there are many drawbacks such as detracting from the aesthetic appearance of the tire.

The present invention was achieved as a result of studies aimed at solving the above-mentioned problems.

Accordingly, an object of the present invention is to provide a pneumatic tire equipped with display media such as characters, two figures, marks, etc., which have a high display effect in relation to the shape of the tire and the tread design.

Means for Solving Problem C] The present invention is a tire that has a toroidal shape and is provided with a display medium such as a character, a figure, a mark, etc. carved on the outer peripheral surface of the tire. It is characterized in that display media having substantially the same shape are overlaid and engraved with main constituent elements having a width of 20 to 80% of the width of the main parts of the elements constituting the media.

[Effect]

It is possible to obtain a pneumatic tire equipped with display media such as characters, figures, marks, etc. that have a high visibility effect in relation to the shape of the tire and the tread design.

〔Example〕

Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.

1 to 6 show pneumatic tires according to embodiments of the present invention, FIG. 1 is a partially cutaway front view explanatory view of the first embodiment, and FIG. 2 is an illustration of the second embodiment. 3 is a partially cutaway front view explanatory diagram of the third embodiment; FIG. 4 is a partially cutaway front view explanatory diagram of the fourth embodiment; FIG. 6 is a front view explanatory diagram showing the main parts of the fifth embodiment, and
The figure is an explanatory front view showing the main parts of the sixth embodiment.

In the figure, E denotes a pneumatic tire according to an embodiment of the present invention, which has a toroidal shape and is constructed by engraving a display medium 10 consisting of characters, two figures, marks, etc. on its outer peripheral surface.

In the present invention, the display medium 1o has a main component having a width of 20 to 80% of the width of the main part of the elements constituting the first surface water medium 101 on the first surface water medium 101. It is constructed by overlapping and engraving the second surface water medium 102 having the same shape as the top.

Note that the first display medium 101 and the second surface water medium 102
It is preferable that the state or color of the swelling surface be different between the two.

To further explain this structure, each of the embodiments shown in FIGS. 1 to 6 is an example in which the display medium 10 is applied to the sidewall S of a pneumatic tire for a passenger car.

First, a first embodiment shown in FIG. 1 will be described.

In the first embodiment, the display medium 10 has the first surface aqueous medium 101 and the main components having a width of 20 to 80% of the width of the main part of the elements constituting the first display medium 10, as described above. and a second surface water medium 102 having substantially the same shape.

The first display medium 101, as shown in the figure,
It is carved at a predetermined uniform depth along the circumferential direction of the tire at a position close to the tread T of the sidewall S.

The engraving depth of the first surface water medium 101 is preferably about 0.1 to 5 fl, although it depends on the size of the tire, and in the first embodiment, the engraving depth is 0.5 fl.

As shown, the second surface water medium 102 is similar to the first surface water medium 1.
01, and the outer surface of this second surface water medium 102 is made to match the level of the outer surface of the sidewall S in this embodiment.

It goes without saying that the level of the outer surface of the second surface water medium 102 may be recessed lower than the level of the outer surface of the sidewall S, or may be made to protrude higher.

In addition, the depth of the first surface water medium 10□ and the second surface water medium 102
The relative height of the tire shall be arbitrarily selected in consideration of the balance with the tire size, tread design, and other designs on the sidewall.

Furthermore, the dimensions of the second surface water medium 102 are the same as those of the first surface water medium 1
It is preferable to set the width X of the grass 2 surface water medium 102 element to the width Y of the grass 2 surface water medium 102 element within 20 to 80% of the width Y of the grass 2 surface water medium 102 element.

This is because if the ratio of Y to X is less than 20%, the impression of the second surface water medium 102 will be weaker than that of the first surface water medium 101, resulting in a lack of balance in the entire display medium such as characters, and if it exceeds 80%, conversely This is because the impression of the surface water medium 101 is weakened, the readability of display media such as characters is deteriorated, and the display effect is reduced.

In addition, in this first embodiment, X/YX100-25% It is set to .

The above-mentioned engravings on the display medium 10 can be overlapped in three or more layers as circumstances permit, and furthermore, the engravings can be made visible by applying (by known means) one-color rubber or the like with different colors between the plurality of display media. The effect can be further enhanced.

Next, the second embodiment I shown in FIG. 2 will be explained.

The feature of the second embodiment is that the first surface water medium 101 is made to protrude beyond the level of the outer surface of the sidewall S, the second surface water medium 102 is kept at the level of the outer surface of the sidewall S, and the second surface water medium 102 is kept at the level of the outer surface of the sidewall S. The point is that the display medium 10 is made visible by engraving into the area.

Further, the protruding height of the first surface water medium 101 is preferably set within a range of 0.1 to 5 B from the outer surface of the sidewall, and in this second embodiment, the height is set to 0.5 B. .

Similar to the first embodiment described above, the level of the second surface water medium 102 can be set higher or lower as appropriate than the level of the outer surface of the sidewall.

Next, a third embodiment shown in FIG. 3 will be described.

The feature of the third embodiment is that the first surface water medium 101 is carved lower than the sidewall outer surface level, and the second surface water medium 102 at the sidewall outer surface level is placed at the bottom left of the first surface water medium 101. It is distinctive in that it is formed by shifting it to the corner and overlapping it.

Furthermore, in this embodiment, the surface of the first surface water medium 10 is
Although it is formed to be smooth like the surface of the surrounding sidewall, the surface of the second surface water medium 102 has thin and relatively shallow vertical grooves a and horizontal grooves nb at predetermined intervals as shown in the figure. It is arranged in a grid pattern.

Next, a fourth embodiment shown in FIG. 4 will be described.

In the fourth embodiment, as in the third embodiment described above, the second surface water medium 102 at the sidewall outer surface level is placed in contrast to the first surface water medium 101 carved lower than the sidewall outer surface level. Although it is formed by being shifted to the lower left corner of the first surface water medium 10+ and overlapping, the feature of this embodiment is that a thin vertical ridge R1 is formed on the surface of the second surface water medium 102.
and lateral direction ridges R2 are provided in a lattice shape at predetermined intervals, while thicker ridges R
is provided around the first surface water medium 101 and the second surface water medium 10z.

In this embodiment, the left side and bottom glue rim of the first surface water medium 101 also serve as the glue rim of the second surface water medium 102.

Next, a fifth embodiment shown in FIG. 5 will be described.

In the fifth embodiment, a second surface water medium 102 whose element width is reduced to approximately half of the first surface water medium 101 provided to protrude from the outer surface of the sidewall is used as the first surface water medium 10. In this example, the level of the second surface water medium 102 is equal to the level of the outer surface of the sidewall.

Furthermore, the surface of the second surface water medium 102 includes a rough surface C formed by corroding the vulcanization mold,
A horizontal striped pattern is formed by alternately arranging the smooth surfaces d of the first surface water medium 101.

Note that this pattern may be a diagonal striped pattern or a vertical striped pattern, and it goes without saying that these striped patterns may be applied to the first surface water medium 10□.

Next, a sixth embodiment shown in FIG. 6 will be described.

In the sixth embodiment, while the second surface water medium 102 is placed in the center of the first surface water medium 10+, the periphery of each display medium is bordered by a ridge R as in the fourth embodiment described above. The surface level of each display medium is equal to the level of the outer surface of the sidewall.

Furthermore, in this embodiment, the entire surface of the second surface water medium 102 is formed with a rough surface C, which is in good contrast with the smooth surface d of the first surface water medium 101 to obtain a good revealing effect. This is so that you can do it.

It goes without saying that the above-mentioned surface conditions may be reversed between the first surface water medium 101 and the second surface water medium 102.

Further, the surface of each display medium can be provided with a large number of thin vertical, horizontal or diagonal grooves or ridges, as long as the purpose is not impaired, or a mesh pattern formed by a combination of these can also be applied.

〔Effect of the invention〕
