Abstract

Proposed is a tire including a pattern forming area provided on a sidewall to display a pattern of predetermined shape, wherein the pattern forming area is formed by continuously arranging a plurality of hexagon-shaped unit patterns, and the unit patterns existing on the edges of the pattern forming area are cut off in shapes to correspond to the shape of the pattern forming area.

First claim

What is claimed is:

1 . A tire comprising:
a pattern forming area positioned on a sidewall to dispose a pattern having a predetermined shape, wherein the pattern forming area includes a plurality of unit patterns, wherein the plurality of unit patterns are disposed adjacent to each other, wherein each unit pattern comprises a plurality of concaved portions and a plurality of protruding portions, wherein each of the plurality of concaved portions includes a first center portion, a first side portion, and a second side portion, wherein the first side portion extends in a first predetermined length from one end of the first center portion and the second side portion extends in a second predetermined length from another end of the first center portion, and wherein each of the plurality of protruding portions includes a second center portion, a third side portion, and a fourth side portion, wherein the third side portion extends in a third predetermined length from one end of the second center portion and the fourth side portion extends in a fourth predetermined length from another end of the second center portion, wherein the plurality of concaved portions and the plurality of protruding portions are arranged alternately, wherein an angle of each of the plurality of concaved portions defined between the first center portion and the first side portion is greater than 90 degrees and less than 180 degrees, wherein angles of the plurality of concaved portions adjacent to each other are different.

2 . The tire according to claim 1 ,
wherein a length of the first center portion is different from a length of another first center portion adjacent to the first center portion.

3 . The tire according to claim 2 ,
wherein the lengths of the first center portions of the plurality of concaved portions increase from a first side of each unit pattern to a second side of each unit pattern.

4 . The tire according to claim 1 ,
wherein a length of the second center portion is different from a length of another second center portion adjacent to the second center portion.

5 . The tire according to claim 4 ,
wherein the lengths of the second center portions of the plurality of protruding portions increase from one side of each unit pattern to another side of each unit pattern.

6 . The tire according to claim 1 ,
wherein an outer edge portion encloses outer ends of the plurality of concaved portions and outer ends of the plurality of protruding portions.

7 . The tire according to claim 6 ,
wherein the outer edge portion has a closed loop.

8 . The tire according to claim 6 ,
wherein the outer edge portion extends along and is disposed adjacent to an outermost concaved portion of the plurality of concaved portions.

9 . The tire according to claim 6 ,
wherein the outer edge portion is positioned higher than the plurality of concaved portions.

10 . The tire according to claim 6 ,
wherein a shape of the outer edge portion is hexagonal.

11 . The tire according to claim 1 ,
wherein the plurality of unit patterns are disposed in contact with each other.

12 . The tire according to claim 1 ,
wherein each of the plurality of unit patterns is symmetrical with respect to a line extending along centers of the first center portions and the second center portions.

13 . The tire according to claim 1 ,
wherein the first side portion and the second side portion are bent in both side directions of the first center portion, respectively.

14 . A tire comprising:
a pattern forming area positioned on a sidewall to dispose a pattern having a predetermined shape, wherein the pattern forming area includes a plurality of unit patterns, wherein the plurality of unit patterns are disposed adjacent to each other, wherein each unit pattern comprises a plurality of concaved portions and a plurality of protruding portions, wherein each of the plurality of concaved portions includes a first center portion, a first side portion, and a second side portion, wherein the first side portion extends in a first predetermined length from one end of the first center portion and the second side portion extends in a second predetermined length from another end of the first center portion, and wherein each of the plurality of protruding portions includes a second center portion, a third side portion, and a fourth side portion, wherein the third side portion extends in a third predetermined length from one end of the second center portion and the fourth side portion extends in a fourth predetermined length from another end of the second center portion, wherein the plurality of concaved portions and the plurality of protruding portions are arranged alternately, wherein an angle of each of the plurality of protruding portions defined between the second center portion and the third side portion is greater than 90 degrees and less than 180 degrees, wherein the angles of the plurality of protruding portions adjacent to each other are different.

15 . A tire comprising:
a pattern forming area positioned on a sidewall to dispose a pattern having a predetermined shape, wherein the pattern forming area includes a plurality of unit patterns, wherein the plurality of unit patterns are disposed adjacent to each other, wherein each unit pattern comprises a plurality of concaved portions and a plurality of protruding portions, wherein each of the plurality of concaved portions includes a first center portion, a first side portion, and a second side portion, wherein the first side portion extends in a first predetermined length from one end of the first center portion and the second side portion extends in a second predetermined length from another end of the first center portion, and wherein each of the plurality of protruding portions includes a second center portion, a third side portion, and a fourth side portion, wherein the third side portion extends in a third predetermined length from one end of the second center portion and the fourth side portion extends in a fourth predetermined length from another end of the second center portion, wherein the plurality of concaved portions and the plurality of protruding portions are arranged alternately, wherein an angle of each of the plurality of concaved portions defined between the first center portion and the first side portion is greater than 90 degrees and less than 180 degrees, wherein the angles of the plurality of concaved portions decrease from a first side of each unit pattern to a second side of each unit pattern.

16 . A tire comprising:
a pattern forming area positioned on a sidewall to dispose a pattern having a predetermined shape, wherein the pattern forming area includes a plurality of unit patterns, wherein the plurality of unit patterns are disposed adjacent to each other, wherein each unit pattern comprises a plurality of concaved portions and a plurality of protruding portions, wherein each of the plurality of concaved portions includes a first center portion, a first side portion, and a second side portion, wherein the first side portion extends in a first predetermined length from one end of the first center portion and the second side portion extends in a second predetermined length from another end of the first center portion, and wherein each of the plurality of protruding portions includes a second center portion, a third side portion, and a fourth side portion, wherein the third side portion extends in a third predetermined length from one end of the second center portion and the fourth side port
