It is a figure which shows the decoration which contains the modification of the polygon pattern of FIG. It is a figure which shows the decoration which contains another modification of the polygon pattern of FIG. It is a figure which shows the decoration which contains another modification of the polygon pattern of FIG.

Hereinafter, an embodiment of a tire according to the present invention will be described based on the drawings.
FIG. 1 is a side view of a tire 1 of the present embodiment. As shown in FIG. 1, the tire 1 of the present embodiment is a pneumatic tire provided with a tread portion 2, a sidewall portion 3 and a bead portion 4.

  A decorative body 5 is provided on the surface of the sidewall portion 3. The decorative body 5 of the present embodiment extends continuously in the tire circumferential direction. The decorative body 5 may be formed intermittently in the tire circumferential direction. In the area of the decorative body 5, characters or the like indicating a brand name, a tire size, and the like may be formed in a concave shape or a convex shape.

  When the tire 1 is an airless tire, the sidewall of the tread ring portion corresponds to the sidewall portion 3. Therefore, the decorative body 5 is formed on the side wall of the tread ring portion.

  The decorative body 5 includes a polygonal pattern 6. The polygonal pattern 6 is configured using a linear pattern 60 made of a protrusion or a groove.

  The height of the linear pattern 60 (the depth when the linear pattern 60 is a groove) is preferably 0.1 mm to 1.0 mm. If the height of the linear pattern 60 is less than 0.1 mm, a sufficient decorative effect may not be obtained. If the height of the linear pattern 60 exceeds 1.0 mm, the decorative effect may become a corner.

  The polygonal pattern 6 may be configured using a linear pattern 60 consisting only of projections, or may be configured using a linear pattern 60 consisting only of grooves, and the projections and grooves are combined The linear pattern 60 may be used.

  The polygon pattern 6 includes a plurality of small polygon patterns 7, a first middle polygon pattern 8, a second middle polygon pattern 9, and a large polygon pattern 10. The first middle polygon pattern 8 and the second middle polygon pattern 9 are larger than the small polygon pattern 7, and the large polygon pattern 10 is larger than the first middle polygon pattern 8 and the second middle polygon pattern 9. .

  By combining the polygonal patterns 6 having different sizes as described above, the impression of the sidewall portion 3 is prevented from being monotonous, and the design and the distinctiveness of the tire 1 are enhanced.

  The small polygon pattern 7 is composed of a plurality of linear patterns 60. In order for the small polygon pattern 7 to form a polygon, the small polygon pattern 7 is formed of three or more (four in the present embodiment) linear patterns 60. Each small polygon pattern 7 has the same number of angles. Thereby, a small pattern is given a sense of unity, and the design of the tire 1 is enhanced. In addition, the small polygonal pattern 7 makes the unevenness of the side wall portion 3 inconspicuous, and improves the appearance performance of the tire 1.

  The first middle polygon pattern 8 is composed of an outline of a set of a plurality of small polygon patterns 7 sharing at least one side 75. In other words, the first middle polygon pattern 8 is divided into two small polygon patterns 7 by one side 75. The first middle polygon pattern 8 in the present embodiment is an outline of a set of a pair of small polygon patterns 7. Such a first middle polygon pattern 8 gives a concentrated feeling to the set of small polygon patterns 7 and enhances the design and identification of the tire 1. In the present embodiment, the small polygon pattern 7 and the first middle polygon pattern 8 have the same number of angles. Thereby, a sense of unity is obtained between the small polygon pattern 7 and the first middle polygon pattern 8.

  The second middle polygon pattern 9 is formed to have a larger area than the small polygon pattern 7. The second middle polygon pattern 9 shares one side 85 with the first middle polygon pattern 8. In the present embodiment, the first middle polygon pattern 8 and the second middle polygon pattern 9 have the same number of angles. The first middle polygon pattern 8 and the second middle polygon pattern 9 preferably have a congruent shape. Thereby, a sense of unity is obtained between the first middle polygon pattern 8 and the second middle polygon pattern 9.

  The large polygon pattern 10 is constituted by the outline of a set of the first middle polygon pattern 8 and the second middle polygon pattern 9. As a result, the light irradiated to the side wall portion 3 is reflected in a complicated manner, and light and shade appear, and the design and identification of the tire are enhanced. In the present embodiment, the first middle polygon pattern 8 and the large polygon pattern 10 have the same number of angles. Thereby, a sense of unity is obtained between the first middle polygon pattern 8 and the large polygon pattern 10. A large polygon pattern 10 is formed by the outline of the set of the first middle polygon pattern 8 and the second middle polygon pattern 9 forming a pair.

  The length L of one side of the large polygon pattern 10 is preferably 3.0 mm to 10.0 mm. If the length L is less than 3.0 mm, it may be difficult to form the small polygon pattern 7. When the length L exceeds 10.0 mm, it may be difficult to form a precise geometric pattern on the sidewall portion 3.

  The polygonal patterns 6 are repeatedly arranged without gaps in the tire circumferential direction and the tire radial direction. As a result, the decorative body 5 continuous in the tire circumferential direction and the tire radial direction is formed on the sidewall portion 3, and the design and identification of the tire 1 are enhanced. The polygonal patterns 6 may be arranged singly or intermittently, and may be repeatedly arranged only in the tire circumferential direction or only in the tire radial direction.

  The second middle polygon pattern 9 preferably does not include the small polygon pattern 7. Such a second middle polygonal pattern 9 changes the density of the linear pattern 60 in the decorative body 5 to construct a complex geometric pattern, and the design and the distinctiveness of the tire 1 are enhanced.

  It is desirable that one side 75 shared by the small polygon patterns 7 is connected to one side 85 shared by the first middle polygon pattern 8 and the second middle polygon pattern 9. As a result, an organic geometric pattern is formed, and the design and identification of the tire 1 are enhanced.

  Each small polygon pattern 7 desirably has the same area. As a result, a precise geometric pattern is formed, and the design and identification of the tire 1 are enhanced.

  The second middle polygon pattern 9 preferably has the same area as the first middle polygon pattern 8. The density of the line pattern 60 in the decorative body 5 is significantly changed, a complicated geometric pattern is constructed, and the design and the distinguishability of the tire 1 are enhanced.

  In the present embodiment, each small polygon pattern 7 is a square pattern. Such a small polygonal pattern 7 can be repeatedly disposed without gaps in the tire circumferential direction and the tire radial direction.

  In the present embodiment, the polygon pattern 6 has three types of large polygon patterns 10a, 10b and 10c. The large polygon patterns 10b and 10c are disposed adjacent to each other in the tire circumferential direction. The large polygon patterns 10b and 10c are disposed on both sides in the tire radial direction of the large polygon pattern 10a. The large polygon patterns 10a, 10b and 10c are preferably parallelograms. By such large polygon patterns 10a, 10b and 10c, the large polygon patterns 10a, 10b and 10c are regularly arranged as described above, and the design and identification of the tire 1 are enhanced.

  The large polygon pattern 10a is a rhombus. Such a large polygon pattern 10a makes it possible to arrange the large polygon patterns 10a, 10b and 10c symmetrically, and the design and identification of the tire 1 are enhanced.

  In the large polygon pattern 10 adjacent in the tire circumferential direction and the tire radial direction, it is desirable that one side 85 shared by the first middle polygon pattern 8 and the second middle polygon pattern 9 be non-parallel. Such a side 85 makes up a complex geometric pattern and enhances the design and identification of the tire 1.

  The interior angle α of the large polygon pattern 10 is preferably 60 ° or 120 °. As a result, the large polygon patterns 10 are regularly arranged, and the design and identification of the tire 1 are enhanced.

  FIG. 4 shows a decorative body 5 including polygonal patterns 6A and 6B which is a modification of the polygonal pattern 6. The configuration of polygon pattern 6 described above may be employed for portions of polygon patterns 6A and 6B which are not described below.

  In the polygon pattern 6A, a first middle polygon pattern 8A is formed by the outline of a set of four small polygon patterns 7A. Each small polygon pattern 7A is congruent with each other, and adjacent small polygon patterns 7A share the side 75A. In other words, the first middle polygon pattern 8 is divided into four small polygon patterns 7 by the three sides 75A. Each side 75A is parallel in one first middle polygon pattern 8A. Thereby, the small polygon pattern 7A becomes a quadrangle.

  The polygonal patterns 6A are repeatedly arranged without gaps in the tire radial direction. The polygon pattern 6A may be repeatedly disposed without gaps in the tire circumferential direction. The polygonal pattern 6A enriches the variation of the decorative body 5 and enhances the design and identification of the tire 1.

  In the polygon pattern 6B, the first middle polygon pattern 8B is formed by the outline of the set of four small polygon patterns 7B. The respective first middle polygon patterns 8B are congruent with each other, and adjacent small polygon patterns 7B share the side 75B. In other words, the first middle polygon pattern 8B is divided into four small polygon patterns 7B by the three sides 75B. Each side 75B is non-parallel in one first middle polygon pattern 8B. Thereby, the small polygon pattern 7B becomes a triangle.

  The polygonal patterns 6B are repeatedly arranged without gaps in the tire radial direction. The polygon pattern 6A may be repeatedly disposed without gaps in the tire circumferential direction. The polygonal pattern 6B enriches the variation of the decorative body 5 and enhances the design and identification of the tire 1.

  As shown in FIG. 4, polygonal patterns 6, 6A and 6B may be mixed in one decoration 5. Such a decorative body 5 further enhances the design and identification of the tire 1.

  FIG. 5 shows a polygonal pattern 6C which is another modified example of the polygonal pattern 6. The figure is a developed view in which linear patterns 60 extending in the tire radial direction are drawn in parallel (the same applies to FIG. 6 described later). The configuration of the above-described polygon pattern 6 or the like may be employed for portions of the polygon pattern 6C which are not described below.

  In the polygon pattern 6C, the small polygon pattern 7C is configured by a triangle. In one polygon pattern 6C, each small polygon pattern 7C is congruent with each other, and adjacent small polygon patterns 7C share the side 75C. Furthermore, the first middle polygon pattern 8C and the second middle polygon pattern 9C sharing the side 85C are also configured by triangles. Furthermore, a large polygon pattern 10C composed of a set of the first middle polygon pattern 8C and the second middle polygon pattern 9C is configured by a quadrangle.

  FIG. 6 shows a polygonal pattern 6D which is another modification of the polygonal pattern 6. The configuration of the above-described polygon pattern 6 or the like may be employed for portions of the polygon pattern 6D which are not described below.

  In the polygon pattern 6D, the three small polygon patterns 7D are configured by triangles. Each small polygon pattern 7D is congruent with each other, and adjacent small polygon patterns 7D share the side 75D. A first middle polygon pattern 8D composed of an outline of a set of three small polygon patterns 7D is formed of a pentagon. Furthermore, the second middle polygon pattern 9D sharing the first middle polygon pattern 8D and the side 85D is also configured by a pentagon. A large polygon pattern 10D composed of an outline of a set of the first middle polygon pattern 8D and the second middle polygon pattern 9D is formed of a hexagon.

  As apparent from FIGS. 3 to 6, the polygon pattern 6 of the present invention can be generalized and abstracted into a polygon having three or more triangles.

  As mentioned above, although the tire 1 of this invention was demonstrated in detail, this invention is changed into a various aspect, without being limited to said specific embodiment, and implemented.
