Abstract

PURPOSE: A motor vehicle tire is provided to protect the groove formed at the tire tread from crack, by preventing stones from being inserted into the groove and allowing the inserted stone to be easily escaped from the groove. CONSTITUTION: A motor vehicle tire includes a tread(1) having grooves(2) formed at the surface of the tread, and each of grooves has a stone insertion preventing member(3) arranged in a spiral manner in the lengthwise direction of the groove. The stone insertion preventing member has a width of 1 to 40mm and a thickness of 0.5 to 5mm, and a distance of 1 to 5mm from the wall of the groove. The stone insertion preventing member pushes, through a flexion-extension motion of the tread, the stone inserted into the groove and permits the stone to be escaped from the groove.

Description

자동차용 타이어 {Pneumatic Vehicle Tire}Automotive Tires {Pneumatic Vehicle Tire}

본 발명은 자용차용 공기입 타이어에 관한 것으로, 특히 트레드에 형성된 그루브에 돌이 끼이는 것을 방지하고, 끼인 돌이 용이하게 빠지게 하는 타이어를 제공하기 위한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire for a private car, and more particularly, to provide a tire that prevents a stone from being caught in a groove formed in a tread and makes it easier to remove the stuck stone.

종래에도 타이어의 트레드부에 설치된 그루브(Groove)에 돌끼임방지구를 형성시켜 돌의 끼임을 방지하도록 하여 왔다. 그러나 종래의 타이어에 설치된 돌끼임 방지구는 단순히 돌의 끼임만을 방지할 뿐 끼인 돌이 빠지게 하는 기능을 가지지 못하는 결점이 있었다. 따라서 일단 그루브에 돌이 끼이면 상당한 시간 그루브에 돌이 끼워져 타이어에 응력과 스트레스를 주어 타이어의 그루브에 크랙을 발생케하여 결과적으로 타이어의 수명을 단축시켜 왔다.Conventionally, a stone jam prevention tool is formed in a groove provided in a tread portion of a tire to prevent a stone jam. However, the anti-twisting tool installed in the conventional tire has a drawback that does not have a function of simply preventing the pinch of the stone, but only to prevent the pinched stone. Therefore, once a stone is stuck in the groove, the stone is inserted into the groove for a considerable time, thereby stressing and stressing the tire, causing cracks in the groove of the tire, and consequently shortening the life of the tire.

이에 본 발명은 트레드에 형성된 그루브에 돌이 끼이는 것을 방지할 뿐만 아니라, 그루브에 돌이 끼인 경우에는 끼인 돌이 용이하게 빠지게 하는 타이어를 제공하기 위한 것이다. 이와같은 목적을 달성하기 위하여 본 발명은 돌끼임 방지구를 나선형으로 형성시킴으로서, 차량의 운행에 따른 트레드부의 굴신에 따라 돌끼임 방지구가 나선형의 방향으로 운동을 하게 하여, 돌끼임 방지구가 그루브에 끼워진 돌을 밀어내어 그루브에 끼인 돌이 빠져 나가게 하는 타이어를 제공하고자 하는 것이다. 이와 같은 본 발명은 타이어의 트레드부가 차량의 운행 중 차체의 하중으로 지면과의 사이에서 끊임 없는 굴신 운동을 한다는 데에서 착안된 것이다. 그리고 이와 같이 굴신운동은 하는 경우 그루브 내부가 나사모양을 이루는 경우 이에 끼인 돌은 나사산의 굴신작용으로 비교적 쉽게 끼인 돌을 배출할 수 있다고 하는 생각에 기초한다. 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Accordingly, the present invention is to provide a tire that not only prevents the stones from being caught in the grooves formed in the tread, but also easily removes the stones if the stones are caught in the grooves. In order to achieve the above object, the present invention forms a swivel prevention tool in a spiral shape, thereby causing the swivel prevention tool to move in a spiral direction in accordance with the bending of the tread part according to the operation of the vehicle, thereby preventing the swivel prevention tool groove It is intended to provide a tire that pushes the stones inserted in the grooves so that the stones caught in the grooves are pulled out. The present invention is conceived in that the tread portion of the tire performs a continuous flexural movement between the ground and the ground by the load of the vehicle body during the operation of the vehicle. In this way, the flexion movement is based on the idea that when the inside of the groove is screwed, the stones caught therein can be ejected relatively easily by the stretching action of the thread. Referring to the present invention as described above is as follows.

1................트레드1 ...... Tread

2................그루브2 ...... groove

3................돌끼임방지구3 ......

본 발명은, 트레드부(1)에 종횡의 그루브(2)를 형성시키고, 그루브(2)에 돌끼임방지구(3)를 설치하여서 된 것에 있어서, 그루브(2)에 설치되는 돌끼임방지구(3)가 그루브(2) 방향으로 기다란 나선형으로 되도록 형성시킨다. 여기서 말하는 "나선형"은 파형이나 첨부된 도면에 도시된 바와 같은 지그재그형을 포함하는 개념이다. 어느 것이나 굴신운동을 하는 경우 끼인 돌을 나사 방향으로 이동시키려 할 것이기 때문이며, 이와 같이 돌끼임방지구(3)에 의하여 이동되는 끼인 돌은 결국 그루브(2)를 빠져 나갈 것이기 때문이다.In the present invention, the vertical and horizontal grooves 2 are formed in the tread portion 1, and the anti-twisting tools 3 are provided in the grooves 2, and the anti-twisting tools 3 provided in the grooves 2 are provided. ) Is formed to be a long spiral in the direction of the groove (2). The term " spiral " as used herein is a concept including a waveform or a zigzag shape as shown in the accompanying drawings. This is because any of them will try to move the pinned stones in the direction of the screw in the case of stretching movement, and thus the pinched stones moved by the pinch stop 3 will eventually exit the groove 2.

돌끼임방지구(3)는 그 폭을 1∼40mm, 그 두께를 0.5∼5mm, 그루브(2)의 벽과의 거리를 1∼5mm로 형성시키는 것이 바람직하다.The pinch prevention tool 3 preferably has a width of 1 to 40 mm, a thickness of 0.5 to 5 mm, and a distance from the wall of the groove 2 to 1 to 5 mm.

이와 같이 구성된 본 발명은, 차량이 돌이 많은 지면을 통과하게 되어, 그루브(2)에 돌이 끼이려 하면, 돌끼임방지구(3)가 1차로 그루브(2)에 돌이 끼이는 것을 방지하고, 그래도 그루브(2)에 돌이 끼이게 되면, 제2차로 나선형으로 형성된 돌끼임방지구(3)가 굴신운동을 하면서 끼인 돌을 이동시키게 되며, 따라서 이러한 이동으로 끼인 돌은 결국 외부로 방출된다. 이와 같이 본 발명의 타이어는 종래의 타이어에 있어서와 같이 타이어에 돌이 끼이는 것을 방지할 수 있을 뿐만 아니라, 이에서 나아가, 타이어에 돌이 끼인 경우 끼인 돌을 배출할 수 있는 기능을 가지게 되어 타이어의 그루브에 크랙이 생기는 일을 억제하여 크랙의 발생으로 인한 타이어의 수명 감소 염려를 크게 불식할 수 있는 효과가 있다.According to the present invention configured as described above, when the vehicle passes through the ground having a lot of stones, and the stones are caught in the grooves 2, the anti-twisting tool 3 prevents the stones from being caught in the grooves 2 primarily. When the stone is caught in (2), the second helical anti-twisting tool 3 formed in the spiral moves the pinched stones during the stretching movement, and thus the stones pinched by this movement are eventually released to the outside. As described above, the tire of the present invention not only prevents the tire from being stuck in the tire as in the conventional tire, but also has a function of discharging the stuck stone when the tire is stuck in the tire. By suppressing the occurrence of cracks, there is an effect that can greatly eliminate the fear of reducing the life of the tire due to the occurrence of cracks.
