Description

롤러 스케이트용 또는 스케이트 보드용 트럭Trucks for roller skates or skateboards
본 발명은 롤러 스케이트용 또는 스케이트 보드용 트럭에 관한 것이다.The present invention relates to a truck for roller skates or skateboards.
롤러 스케이트는 신발 바닥에 붙는 프레임, 트럭 및 롤러를 포함하고 있고, 그리고 스케이트 보드는 데크, 트럭, 및 롤러를 포함하고 있다.Roller skates include a frame, truck and rollers that attach to the sole of a shoe, and skateboards include a deck, truck, and rollers.
트럭은 프레임 또는 데크와 롤러를 연결해주는 부품이다The truck is the part that connects the frame or deck and the rollers.
트럭은 베이스 플레이트에 행거를 킹핀으로 연결시켜 놓은 형태이고, 사실상 스케이트 보드 또는 신발을 지지해주는 뼈대이다. 프레임 또는 데크 앞뒤로 1개씩 총 2개가 장착된다.The truck is a form in which a hanger is connected to a base plate with a kingpin, and is actually a skeleton that supports a skateboard or a shoe. A total of two are installed, one at the front and back of the frame or deck.
롤러 스케이터(roller skater)나 스케이트보더(skateboarder)에게는 평형을 유지하는 것이 높은 관심의 대상이며, 이러한 평형유지는 도약, 방향전환, 회전 등을 행하여야 하는 전문 스케이터나 보더들에게는 어려움이 있다.Maintaining balance is of great interest to roller skaters and skateboarders, and maintaining such balance is difficult for professional skaters or boarders who need to jump, change direction, and turn.
이러한 평형유지에 조력하는 장치가 트럭이다.A device that assists in maintaining this balance is a truck.
상기 트럭은, 킹핀과 행거 사이에 개재된 부싱 및 콘부싱 그리고 피봇컵에 삽입장착된 피봇부싱에 의해 좌우 밸런스를 조절해주고, 터닝 주행을 조절해주며, 완충을 해주는 작용을 한다.The truck controls left and right balance by a bushing and a cone bushing interposed between the kingpin and the hanger, and a pivot bushing inserted and mounted in a pivot cup, and controls turning driving, and acts as a buffer.
하지만, 상기 개시된 트럭은, 주행방향에서 나란하게 킹핀의 중심축선과 피봇컵의 중심축선이 배치되어 있기 때문에, 주행방향에서 볼 때 좌우의 경사도가 작아, 터닝 주행시에 또는 곡선 주행시에 전륜휠과 후륜휠이 C자형 궤적으로 배열되지 못하여, 터닝 반경이나 곡선 반경이 커서, 롤러 스케이터나 스케이트보더에게 자유로운 스케이팅을 제공할 수 없다고 하는 문제점을 가진다.However, in the truck disclosed above, since the central axis of the kingpin and the central axis of the pivot cup are arranged side by side in the running direction, the left and right inclinations are small when viewed from the running direction. Since the wheels are not arranged in a C-shaped trajectory, the turning radius or the curvature radius is large, so there is a problem that free skating cannot be provided to roller skaters or skateboarders.
