Description

공기주입식 서프 보드 및 이의 제조 방법Inflatable surfboard and manufacturing method thereof
본 발명은 공기주입식 서프 보드에 관한 것으로, 보다 상세하게는 하면에 오목하거나 볼록한 직선부를 형성하여 보드의 직진성이 향상되도록 하면서 중심 잡기가 보다 간편하면서 안정적으로 이루어지도록 하는 공기주입식 서프 보드 및 이의 제조 방법에 관한 것이다.The present invention relates to an inflatable surfboard, and more particularly, to an inflatable surfboard, which forms a concave or convex straight part on the lower surface to improve the straightness of the board while making centering easier and more stable, and a method for manufacturing the same is about
최근 생활수준의 향상에 따라 각종 레저 활동 및 레저 스포츠를 즐기는 인구가 증가되고 있다. 특히 수상에서 즐길 수 있는 레저 스포츠 중 대표적인 것으로 서프 보드(Stand Up Paddle board : SUP board)를 예로 들 수 있으며, 이는 투어링, 카약킹, 파도타기 또는 윈드서핑 등의 용도로 사용할 수 있다.Recently, with the improvement of living standards, the number of people who enjoy various leisure activities and leisure sports is increasing. In particular, a surf board (Stand Up Paddle board: SUP board) may be cited as a representative among leisure sports that can be enjoyed on the water, and it can be used for touring, kayaking, surfing or windsurfing.
이러한 서프 보드는 보드 판재에 사람이 양발도 딛고 올라서기도 하고, 보드 판재에 상체를 대고 엎드려서 파도를 타기도 하는 등 다양한 방법으로 사용될 수 있다.Such a surfboard can be used in various ways, such as when a person climbs up with both feet on the board board, and rides a wave by lying face down on the board board.
그런데, 일반적으로 서프 보드는 그 크기가 길이 약 1.5 ~ 4.5m, 너비 약 50 ~ 100㎝, 두께 약 7 ~ 15㎝ 정도여서 상당한 부피를 갖는데, 종래에는 목재를 사용하여 제조되어 그 무게가 50 kg 이상에 달하였다. 따라서, 보관뿐만 아니라 운반 등이 용이하지 않은 문제점이 있었다.However, in general, the size of the surfboard is about 1.5 to 4.5m in length, about 50 to 100cm in width, and about 7 to 15cm in thickness, so it has a considerable volume. Conventionally, it is manufactured using wood and its weight is 50 kg reached above. Therefore, there is a problem in that it is not easy to carry as well as to store.
이러한 문제점을 해결하기 위해 폴리우레탄이 서핑용 보드의 소재로서 소개되었다. 하지만, 서핑용 보드는 일정한 크기를 가져야 하므로 그 무게의 감소에도 한계가 존재하며, 폴리우레탄도 경질 소재이므로, 보관이나 운반 등의 문제점이 여전히 해결되지 못하고 있다.In order to solve this problem, polyurethane has been introduced as a material for surfboards. However, since the surfboard has to have a certain size, there is a limit to the reduction of its weight, and since polyurethane is also a hard material, problems such as storage or transport are still not solved.
또한 레저 활동이 증가됨에 따라, 전문적인 파도타기나 윈드 서핑 외에도 물놀이 시설이 구비된 놀이공원에서 즐길 수 있는 간단한 서핑도 최근 소개되고 있는데, 종래의 서핑용 보드는 이러한 시설물 내부에서 사용하기에는 적합하지 않은 문제점이 있다.In addition, as leisure activities increase, in addition to professional surfing and windsurfing, simple surfing that can be enjoyed at an amusement park equipped with a water play facility has been recently introduced. Conventional surfing boards are not suitable for use inside these facilities. There is a problem.
상기한 문제점을 해소하기 위해 최근에는 고무 재질의 공기튜브를 사용하여 서프 보드를 제작하고 있고, 이러한 공기튜브는 공기의 주입에 의해 보드의 형태를 가지게 되고, 공기의 배출에 의해 운반 및 보관이 용이한 형태가 되어 사용상의 편의성이 상당히 좋아진다.In order to solve the above problems, recently, a surfboard is manufactured using an air tube made of a rubber material. The air tube has a board shape by injection of air, and transportation and storage are easy by discharge of air. In one form, the convenience of use is greatly improved.
근래에는 공기튜브의 형태를 유지하도록 형태유지라인이 내설된 공간지를 이용한 공기튜브가 공기주입식 서프 보드에 많이 적용되고 있다.Recently, an air tube using a space paper with a built-in shape maintaining line to maintain the shape of the air tube has been widely applied to the inflatable surfboard.
그런데, 상기와 같은 종래 기술에는 다음과 같은 문제점이 있다.However, the prior art as described above has the following problems.
종래의 공기주입식 서프 보드는 그 하면이 평평하게 형성되어 보드 자체의 직진성이 적절히 보장되지 못하여 사용상의 불편함이 상존하는 문제점이 있었다.The conventional air-injected surf board has a flat bottom surface, so that the straightness of the board itself is not properly guaranteed, so there is a problem that inconvenience in use exists.
또한, 종래의 서프 보드는 그 하면이 평평하게 형성되어 수면에서 여러 방향으로 미끄러질 수 있고, 그에 따라 탑승한 사용자가 균형을 잃으면 쉽게 넘어지는 등 중심 잡기가 어려운 문제점이 있었다.In addition, the conventional surfboard has a problem in that its lower surface is formed flat, so that it can slide in various directions on the water surface.
