자전거 통 타이어의 단면구조{SECTIONAL STRUCTURE OF TUBLESS TIRE OF A BICYCLE}Sectional structure of bicycle barrel tires {SECTIONAL STRUCTURE OF TUBLESS TIRE OF A BICYCLE}

본 고안은 자전거 통타이어의 단면 구조에 관한 것이다.The present invention relates to a cross-sectional structure of a bicycle tong tire.

일반적으로 자전거 타이어는, 속이 빈 C형 단면의 원호상 고무타이어의 내부에 압축공기를 주입하는 고무 튜브가 내장하게 된 구성으로 되어 있다.In general, bicycle tires have a structure in which a rubber tube for injecting compressed air is embedded inside a hollow C-shaped circular rubber tire.

또 튜브가 없는 타이어로서 원호상의 타이어의 내부가 중공으로 형성하고 중공으로 된 격실에 유동성의 고무액을 주입하여 못 등이 타이어에 박혀도 고무액이 파열된 부분을 치유하게 된 것이 있다.In addition, there is a case in which a tubeless tire is formed in the shape of a hollow tire in a hollow shape, and a fluid rubber fluid is injected into the hollow compartment to heal the portion where the rubber fluid has ruptured even when nails or the like are stuck in the tire.

또 타이어체의 내부에 지름방향의 방사상으로 다수의 원통공을 형성하고 원통공의 양단부를 비드(beat)부와 트래드(trade)부로 차폐되게 성형하여 노펑크를 목적으로 한 타이어가 있다.In addition, there is a tire for the purpose of no puncture by forming a plurality of cylindrical holes radially in the radial direction inside the tire body and shielding both ends of the cylindrical holes with a bead part and a tread part.

또 타이어의 소재에 발포성물질을 혼합 하여 가류(加硫)성형중에 다수의 독립성 기포가 발포되게 하여 튜브가 없는 노펑크 타이어로 성형된 것이 있다. In addition, the foam material is mixed with the tire material to allow a large number of independent bubbles to be foamed during vulcanization molding, and molded into a tubeless no-punk tire.

종래의 자전거 타이어에 있어서, 튜브가 내장된 것은 타이어에 펑크가 나면 튜브의 공기가 빠지게 되어, 타이어가 납작하게 압착되기 때문에 주행할 수 없고 고속주행시에 펑크가 발생하면 더욱 위험한 사고가 발생되는 문제점이 있었다.In conventional bicycle tires, the built-in tube has a problem in that when the tire is punctured, the air is drawn out of the tube, and the tire is flattened so that the tire cannot be driven, and when the puncture occurs during high-speed driving, a more dangerous accident occurs. there was.

또 튜브가 없이 통타이어의 내부에 고무액을 주입하고 압축공기가 충전된 것은 자전거의 주행시 타이어의 내부에 충전된 고무액이 회전 원심력에 의해 타이어의 어느 한 부분에 밀착되어 타이어의 질량이 고무액이 부착된 부분으로 편위되어 바퀴의 회전진동이 발생하게 되고 또 타이어가 예리한 물질에 의해 선형(線形)으로 절결된 경우에는 타이어의 내부에 충전(充塡)된 고무액에 의하여 파손된 부분의 치유가 어렵기 때문에 역시 자전거를 탈 수 없는 문제가 있다. In addition, the rubber liquid is injected inside the tong tire without a tube, and the compressed air is filled. The rubber fluid filled inside the tire adheres to any part of the tire by the centrifugal force when the bicycle is driven, and the mass of the tire is If the wheel is vibrated due to the attached part and the tire is cut in a linear shape by a sharp material, the damaged part is damaged by the rubber liquid filled in the tire. There is also a problem that can not ride bikes because it is difficult.

또 튜브가 없이 통타이어체의 내부에 지름방향으로 다수의 원통공이 형성된 것은 펑크의 문제는 없으나 타이어의 쿠션이 미흡하여 도로의 요철에 의한 자전거의 주행진동을 용이하게 완충할 수 없는 문제점이 있었다.In addition, a large number of cylindrical holes formed in the tubular tire body in the radial direction without the tube does not have a problem of puncture, but there is a problem in that the cushion of the tire is insufficient to easily cushion the driving vibration of the bicycle due to the unevenness of the road.

또 발포성 타이어는 타이어의 성형시 타이어체의 내부에 형성된 독립기포의 분포를 제어할 수 없기 때문에 타이어의 무게중심이 어느 한쪽으로 쏠리는 등 균일한 탄성분포를 가진 일정한 품질의 타이어의 성형이 어려운 문제점이 있었다. In addition, since a foam tire cannot control the distribution of independent bubbles formed inside the tire body when the tire is molded, it is difficult to form a tire of uniform quality with a uniform elastic distribution such that the center of gravity of the tire is directed to either side. there was.

본 고안은 종래의 이러한 문제점을 시정하기 위하여 고안된 실용신안등록출원 제2008-0013671호와 관련된 계속고안(繼續考案)에 속하는 것으로 탄성재질의 자 전거 통타이어(튜브가 없는 타이어)에 있어서, 타이어체의 원호상 단면 내부에 다수개의 타원홈의 긴쪽이 타이어 원호 중심방향을 향하도록 트래드(trade)의 돌출부 위치에 배열 형성하고 타이어체의 일측방으로 형성된 타원홈의 개구부가 차폐되도록 다수의 마개가 상기 타원홈의 개구부와 상응하게 배열 형성된 측면밴드를 상기 타이어체의 한쪽 면에 접착하여 각 타원홈의 개구부가 마개로 차폐되고 타원홈에 공기가 상압으로 채워진 타원홈의 격실을 구성하여서 된 것이다. The present invention belongs to the continuation design related to Utility Model Application No. 2008-0013671, which is designed to correct such problems in the prior art, and in the case of an elastic bicycle tire (a tubeless tire), the tire body A plurality of stoppers are formed so that the long side of the plurality of elliptical grooves in the arcuate cross section of the tread is arranged at the position of the protrusion of the trade so as to face the direction of the center of the tire arc and the opening of the elliptical groove formed to one side of the tire body is shielded. The side bands formed to correspond to the openings of the ellipse grooves are bonded to one side of the tire body to form an compartment of the ellipse grooves in which the openings of the ellipse grooves are shielded with a stopper and the air is filled with air at normal pressure.

본 고안의 타이어의 비드를 자전거의 휠의 림(rim)에 장착하고 타이어에 압축공기의 주입없이 자전거를 탄다. 본 고안의 타이어는 원호상의 타이어체에 타원홈으로 된 격실이 타이어의 원호 중심부를 향하여 균일하게 배열되어 있기 때문에 타이어체의 질량이 전체적으로 균형 있게 분포되어 타이어의 회전시 무게 중심에 밸런스가 유지되어 회전진동이 없다.The bead of the tire of the present invention is mounted on the rim of the wheel of the bicycle and rides the bicycle without injecting compressed air into the tire. In the tire of the present invention, since the compartments of the elliptical groove are uniformly arranged toward the center of the arc of the tire, the mass of the tire body is distributed in a balanced manner, and the balance is maintained at the center of gravity when the tire is rotated. No vibration

또 자전거의 주행시, 타이어 트래드와 노면과의 마찰로 발생된 열이 타이어체에 전달되어 각 격실에 채워진 공기압이 마찰열에 의해 압력이 상승된다. 따라서 타원홈으로 된 격실은 팽창력이 유지되고 또 타이어의 측판과, 측면밴드 및 격실을 둘러싼 측벽의 탄성적인 지지력에 의해, 자전거를 탄 사람의 체중이나 하중으로 타이어가 납작하게 변형되지 않고 통타이어의 기본형태를 유지하면서 자전거의 주행진동이 용이하게 완충되어 안락하게 자전거를 탈 수 있다. When the bicycle is running, heat generated by the friction between the tire tread and the road surface is transmitted to the tire body, and the air pressure filled in each compartment is increased by the frictional heat. Therefore, the compartments of the elliptical grooves maintain the inflation force and the elastic support of the side plates of the tires, the side bands and the side walls surrounding the compartments do not flatten the tires due to the weight or load of the cyclist, While maintaining the basic shape, the driving vibration of the bicycle can be easily cushioned to allow comfortable riding.

본 고안은 자전거의 통타이어에 있어서, 타이어의 원호상 단면 내부에 다수의 타원홈의 장축(長軸)이 타이어의 원호 중심부를 향하도록 나란히 배치되게 형성 하여 공기가 밀폐된 타원홈의 격실을 구성하였기 때문에 격실에 밀폐된 공기압의 쿠션작용과, 타이어의 측판과, 측면밴드 및 격실을 둘러싼 측벽의 탄성적인 지지력의 결합으로 자전거를 탄 사람의 체중이나 하중에 의하여 타이어가 납작하게 변형됨이 없이 자전거의 주행진동의 완충작용이 향상되어 보다 안락하게 자전거를 탈 수 있다.The present invention is to form a compartment of the air-sealed ellipse groove by forming the long axis of the plurality of ellipse grooves side by side toward the center of the circular arc of the tire in the cylindrical tire of the bicycle. Due to the combination of the cushioning of the air pressure sealed in the compartment and the elastic support of the side plate of the tire, the side bands and the side wall surrounding the compartment, the tire is not flattened by the weight or load of the cyclist. The shock absorbing effect of the driving vibration is improved, so you can ride the bicycle more comfortably.

제1도 및 제2도에 표시된 바와 같이, 탄성재질로 된 원호상의 자전거 타이어에 있어서, 자전거 휠의 림에 타이어를 장착하는 비드(1b)가 타이어(T)의 내주면에 납작한 판상으로 형성되고 지면에 접촉되는 요철형의 트래드(1t)가 타이어(T)의 외주면에 형성된 타이어체(1)의 원호상 단면의 내부에 다수개의 타원홈(2)의 장축(a)이 타이어의 원호 중심부를 향하도록 측벽(w)을 두고 배열 형성한다. 이때 측벽(w)의 중심선(y)은 각각 타이어의 중심부를 향하고 있다. 제3도 및 제4도에 표시된 바와 같이, 상기 타원홈(2)은 관통공이 아니고 측판(1s)으로 막혀 있으며, 타원홈(2)의 한쪽 측면에 형성된 개구부(2u)를 차폐하도록 다수의 마개(3t)가 타원홈(2)의 개구부(2u)와 상응하게 배열 형성된 원호상의 탄성질 측면밴드(3)를 상기 타이어체(1)의 한쪽 측면에 접착하여 각 타원홈(2)의 개구부(2u)가 마개(3t)로 차폐되고 공기가 상압(常壓)으로 채워진 타원홈의 격실(2a)을 구성하여 된 것이다. As shown in Figs. 1 and 2, in the circular arc-shaped bicycle tire made of elastic material, a bead 1b for mounting the tire on the rim of the bicycle wheel is formed in a flat plate shape on the inner circumferential surface of the tire T, and the ground The long shafts a of the plurality of elliptical grooves 2 are directed toward the circular arc center portion of the tire in an arcuate cross section of the tire body 1 formed on the outer circumferential surface of the tire T with an uneven tread 1t in contact with the tire. The side wall w is arranged so as to be formed. At this time, the centerline y of the side wall w faces the center of the tire, respectively. As shown in FIGS. 3 and 4, the elliptical groove 2 is not a through hole but is blocked by the side plate 1s, and a plurality of plugs are provided to shield the opening 2u formed on one side of the elliptical groove 2. An opening of each elliptic groove 2 is formed by adhering an arc-shaped elastic side band 3, which is formed to correspond to the opening 2u of the elliptical groove 2, on a side surface of the tire body 1, 3t. 2u) is made up of a compartment 2a of an elliptical groove which is shielded with a stopper 3t and filled with air at normal pressure.

본 고안의 실시에 있어서, 상기 타이어체의 타원홈(2)은 한쪽 측면에 타원홈(2)의 개구부(2u)가 형성되어 있기 때문에 타이어 성형의 좌우 할금형(割金型)에 의하여 용이하게 성형할 수 있다.In the practice of the present invention, since the opening 2u of the elliptical groove 2 is formed at one side of the elliptical groove 2 of the tire body, it is easily possible by the right and left halting mold of the tire molding. It can be molded.

이와 같이 된 본 고안은 타이어(T)의 비드(1b)를 도시되지 않은 자전거 휠의 림에 장착하고 타이어에는 압축공기를 주입함이 없이 자전거를 탄다.자전거의 주행시, 자전거의 하중에 의하여 타이어체(1)의 비드(1b)와 지면에 접지된 트래드(1t) 사이의 타이어체(1)가 압력을 받아 타이어에 마찰열이 발생한다. 따라서 타원홈(2)의 격실(2a)에 밀폐된 공기는 압력이 상승되어 강한 팽찰력이 유지된다. 또 타이어(T)의 일측판(1s)과, 측면밴드(3)과, 배열된 타원홈(2) 사이에서 방사형으로 연결된 측벽(w)의 탄성적 지지력 및 상기 격실의 공기압력에 의해 자전거를 탄 사람의 체중이나 하중에 의하여 타이어가 납작하게 변형되는 일이 없고 자전거의 주행진동이 양호하게 완충된다. According to the present invention, the bead 1b of the tire T is mounted on the rim of a bicycle wheel (not shown) and the bicycle is ride without injecting compressed air into the tire. The tire body 1 is pressurized between the bead 1b of (1) and the tread 1t grounded on the ground, and friction heat is generated in the tire. Therefore, the air sealed in the compartment 2a of the elliptical groove 2 is increased in pressure to maintain a strong traction force. In addition, the bicycle is supported by the elastic support force of the side wall w radially connected between the one side plate 1s of the tire T, the side band 3, and the arranged elliptical grooves 2 and the air pressure of the compartment. The tire is not flattened by the weight or load of the rider, and the driving vibration of the bicycle is well buffered.

또 통타이어임으로 펑크의 우려가 없이 종래의 통타이어에 비하여 보다 안전하고 안락하게 자전거를 탈 수 있다.In addition, it is possible to ride a bicycle more safely and comfortably than conventional tong tires without fear of puncture due to tong tires.
