본 발명은, 림에 장착된 타이어의 비드부가 미끄러지는 현상을 방지하기 위한 것이다.The present invention is to prevent the phenomenon that the bead portion of the tire mounted on the rim slips.

종래에는 림의 표면에 요철부를 형성시키거나 타이어의 비드부 바닥면에 절삭홈이나 반구형 홈을 형성시킴으로서 비드부의 바닥과 림의 표면상에 저항을 부여하여 슬립을 방지하려고 하는 등의 기술이 알려져 왔으나, 이들은 타이어와 휠의 접촉 불균일성을 유발하고 타이어의 장착시 타이어의 변형을 유발할 염려가 있었던 것이다.Conventionally, there have been known techniques for forming slips on the surface of the rim or forming cutting grooves or hemispherical grooves on the bottom of the bead of the tire to prevent slippage by imparting resistance on the bottom of the bead and the surface of the rim. In other words, they caused a nonuniform contact between the tire and the wheel and a deformation of the tire when the tire was mounted.

이에 본 발명은, 비드부의 림체크라인으로부터 림프로텍트 바 사이에 원주방향으로 돌출띠를 형성시키되, 돌출띠를 원주방향으로 파형이나 지그재그 형태가 되게 형성시키며, 한편, 타이어의 비드부 외면부와 접하는 림의 벽내면에도 위 돌출띠에 대응하는 요홈부가 형성되게 하여, 돌출띠가 요홈부에 결합되어 타이어의 비드부와 휠의 림의 결합이 많은 접촉 면적을 가지면서 결합되게 하여 비드부의 미끄러짐을 방지하고 비드부의 이탈을 방지할 수 있게 한 것인 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Accordingly, the present invention, while forming a protruding band in the circumferential direction between the rim check line of the bead portion and lymphatic tract bar, the protruding band is formed in the form of a wave or zigzag in the circumferential direction, while contacting the outer surface of the bead portion of the tire In the wall of the rim, grooves corresponding to the upper projection band are formed on the inner surface of the rim, and the projection band is coupled to the groove so that the bead portion of the tire and the rim of the wheel are combined with a large contact area to prevent slipping of the beads It is to be possible to prevent the separation of the bead portion, this invention will be described with reference to the accompanying drawings as follows.

트레드와 사이드월 및 비드부로 구성된 것에 있어서, 본 발명은, 비드부(가)의 림체크라인(2)으로부터 림프로텍트 바(1) 사이에 원주방향으로 돌출띠(3)를 형성시켜서 된 것을 특징으로 한다. 나아가, 본 발명은 위의 돌출띠(3)를 원주방향으로 파형이나 지그재그 형태가 되게 형성시키는 것을 제2의 특징으로 한다. 돌출띠(3)는 그 상부 두께(31)를 하부 두께(32)보다 얇게 형성시키어 휠로부터의 탈부착을 용이하게 함이 바람직하다.The present invention comprises a tread, a sidewall, and a bead portion, wherein the present invention is formed by forming a protruding band (3) in a circumferential direction between the rim check line (2) of the bead portion and the lymphocyte bar (1). It is done. Further, the present invention is characterized in that the above-described protruding strip 3 is formed to have a wave shape or a zigzag shape in the circumferential direction. The protruding band 3 preferably forms the upper thickness 31 thinner than the lower thickness 32 to facilitate detachment from the wheel.

한편, 타이어의 비드부 외면부와 접하는 림(4)의 벽내면(41)에도 위 돌출띠(3)에 대응하는 요홈부(42)가 형성되게 하는 경우, 본 발명의 타이어를 이러한 휠에 장착하면, 타이어 비드부(가)의 돌출띠(3)가 휠의 요홈부(42)에 결합되어, 타이어의 비드부와 휠의 림의 결합이 많은 접촉 면적을 가지면서 결합되게 하고, 그리하여 비드부의 미끄러짐을 방지하고 비드부의 이탈을 방지할 수 있게 한다.On the other hand, when the groove portion 42 corresponding to the upper projection band 3 is formed on the wall inner surface 41 of the rim 4 which is in contact with the bead outer surface of the tire, the tire of the present invention is mounted on such wheel. The lower surface of the tire bead portion (A) is coupled to the groove 42 of the wheel so that the engagement of the bead portion of the tire and the rim of the wheel has a large contact area, thereby engaging the bead portion. It is possible to prevent slipping and to prevent the bead from coming off.

이와 같이 구성된 본 발명은, 위에서 본 바와 같이, 타이어의 비드부 외면부와 접하는 림(4)의 벽내면(41)에 위 돌출띠(3)에 대응하는 요홈부(42)가 형성되게 하는 경우, 본 발명의 타이어를 위와 같은 휠에 장착하면, 타이어 비드부(가)의 돌출띠(3)가 휠의 요홈부(42)에 결합되어, 타이어의 비드부와 휠의 림의 결합이 많은 접촉 면적을 가지면서 결합되게 할 뿐 아니라, 돌출띠(3)가 원주방향으로 파형 또는 지그재그 형을 이루고 있어 타이어의 원주방향 미끄러짐이 방지된다. 뿐만 아니 라 이러한 미끄럼방지기능은 타이어의 휠로부터의 이탈을 방지하는 효과를 낳을 뿐 아니라, 타이어와 휠이 돌출띠(3)와 요홈부(42)에 의하여 타이어 이탈 방향으로도 저항을 제공하여 타이어 이탈 방지 효과를 상승시키는 효과가 있다.According to the present invention configured as described above, when the groove portion 42 corresponding to the upper projection band 3 is formed on the inner wall 41 of the rim 4 in contact with the bead outer surface of the tire, as shown above, When the tire of the present invention is mounted on the wheel as described above, the protruding band 3 of the tire bead part is coupled to the groove 42 of the wheel, so that the contact between the bead part of the tire and the rim of the wheel is many. In addition to having an area to be coupled, the protruding band 3 is wavy or zigzag in the circumferential direction, thereby preventing the tire from circumferentially sliding. In addition, the anti-slip function not only prevents the tire from being separated from the wheel, but also provides resistance to the tire from the tire and the wheel by the protruding bands 3 and the recesses 42 in the tire disengaging direction. There is an effect of increasing the separation prevention effect.
