Description

딩기정의 밸러스트 탈부착 구조{Ballast structure of dinghy boat}Ballast structure of dinghy boat

본 발명은 딩기정의 밸러스트 탈부착 구조에 관한 것으로, 보다 상세하게는 소형보트, 특히 딩기정의 센터보드에 중량물인 밸러스트를 손쉽게 탈부착할 수 있으며 부착시에는 안정적이고 견고한 상태를 유지할 수 있도록 하기 위한 딩기정의 밸러스트 탈부착 구조에 관한 것이다.
The present invention relates to a ballast detachable structure of a dinghy, more specifically, a small ball, in particular a ballast of a dinghy for making it possible to easily attach and detach a heavy ballast to a center board of a dinghy and to maintain a stable and solid state when attached. It relates to a removable structure.

일반적으로, 딩기정은 갑판이 없는 작은 배를 의미하는 것으로, 엔진과 선실을 갖추지 않은 1~3인용의 소형 세일 요트(sail yacht)를 가리킨다. In general, a dinghy refers to a small ship without a deck, and refers to a small sail yacht for one to three persons without an engine and a cabin.

대개 딩기정은 엔진이 없이 작은 돛과 바람의 힘으로만 움직이기 때문에 주로 연안이나 강 또는 호수에서 레포츠용으로 사용되는데, 윈드서핑도 딩기정에 속한다. Usually, dinghys are used for small sports on coasts, rivers or lakes because they are driven only by small sails and wind forces without engines. Windsurfing is also a dinghy.

또한 선실과 엔진을 갖춘 세일 요트는 크루저(cruiser)라고 구분하며, 특히 외국에서는 규모가 큰 배를 요트라고 부르고 작은 돛배는 세일 딩기(sail dinghy)라고 부른다. In addition, sail yachts with cabins and engines are classified as cruisers, and in particular, large ships are called sailboats and small sailboats are called sail dinghy.

올림픽경기대회의 요트 종목은 모두 딩기를 이용하는데, 전장과 전폭, 세일 면적, 선체 중량, 승정 인원수에 따라 16개 종목으로 나뉜다.All yachts of the Olympic Games use dinghys, which are divided into 16 events according to the length, width, sail area, hull weight and number of passengers.

상기 딩기정의 선체 중앙의 수면 아래쪽에는 센터보드가 길이방향으로 형성되어지는데, 상기 센터보드는 용골(KEEL)이 횡방향으로의 저항을 받지 않는 구조를 갖는 선박의 수면 아래쪽에 횡방향으로 저항을 생기게 하는 것으로, 일반적으로 널판지 모양이며, 물속에서 올렸다 내렸다 할 수 있는 구조를 갖는다.The center board is formed in the longitudinal direction below the water surface of the hull center of the dinghy, the center board causes resistance in the transverse direction below the water surface of the vessel having a structure that the keel (KEEL) does not receive the resistance in the transverse direction In general, it is a board-like shape, and has a structure that can be raised and lowered in the water.

다시 말해 센터보드는 리보드를 선체 중앙에 옮겨 놓은 것과 같은 것으로, 리보드는 일종의 저항판 역할을 해 조류나 바람에 의해 선체가 횡쪽으로 밀리는 것을 방지하게 된다.
In other words, the centerboard is like moving the reboard in the center of the hull. The reboard acts as a kind of resistance plate to prevent the hull from being pushed laterally by birds or wind.

그런데 종래의 딩기정은 크루저 선박과는 달리 밸러스트가 없기 때문에 바람에 따라 적절한 조치를 하지 않으면 쉽게 전복되는 단점을 갖는다.
By the way, the conventional dinghy has a disadvantage that unlike the cruiser ship, because there is no ballast, it is easily overturned unless appropriate measures according to the wind.

상기한 바와 같은 목적을 성취하기 위한 본 발명은 딩기정의 센터보드 하부에 밸러스트를 형성함에 있어, 상기 센터보드의 하부에 통공을 형성하고, 밸러스트는 센터보드보다 높은 비중을 갖는 중량물로 이루어지되 상기 밸러스트의 상부 중앙에는 길이방향으로 센터보드 삽입홈이 형성되고, 상부 양측에는 센터보드 삽입홈을 관통하는 볼트체결공이 형성되어 상기 센터보드 삽입홈에 삽입된 센터보드를 볼트와 너트에 의해 결합되도록 구성됨을 특징으로 한다.The present invention for achieving the object as described above in forming a ballast in the lower centerboard of the dinggi, forming a through hole in the lower portion of the centerboard, the ballast is made of a weight having a higher specific gravity than the centerboard, but the ballast A center board insertion groove is formed in a longitudinal direction at the upper center of the bolt, and bolt fastening holes penetrating the center board insertion grooves are formed at both upper sides thereof so that the center board inserted into the center board insertion groove is coupled by a bolt and a nut. It features.

또한 본 발명에 있어 상기 밸러스트는 유선형 형상으로 구성됨을 특징으로 한다.
In the present invention, the ballast is characterized in that it is configured in a streamlined shape.

이처럼 본 발명은 종래 밸러스트를 구비하지 않는 딩기정의 센터보드 하부에 밸러스트를 형성할 수 있도록 하되, 상기 밸러스트를 딩기정의 센터보드 하부에 신속하게 탈부착 가능토록 하여 선박 체급에 따른 복원력을 조절할 수 있도록 하는 효과를 갖는다.As described above, the present invention allows the ballast to be formed on the lower portion of the centerboard of the dinghy which does not have the conventional ballast, but the ballast can be quickly attached to and detached from the lower portion of the centerboard of the dinghy. Has

또 본 발명은 센터보드 하부에 장착하되 밸러스트 상부에 삽입홈을 형성하여 센터보드를 삽입하고 이를 측면으로 부터 체결수단에 의해 체결함으로써 견고하고 안정적인 결합을 가능하게 하는 효과를 갖는다.In another aspect, the present invention is mounted on the center board lower portion, but the insertion groove is formed in the upper portion of the ballast to insert the center board and to fasten it by the fastening means from the side to enable a strong and stable coupling.

또한 본 발명은 밸러스트를 유선형으로 형성함으로써 유도항력(induced drag)의 감소로 인하여 물의 저항을 최소화할 수 있는 매우 유용한 발명인 것이다.
In addition, the present invention is a very useful invention that can minimize the resistance of the water due to the reduction of the induced drag (induced drag) by forming the ballast in a streamlined form.

본 발명은 딩기정(100)의 센터보드(110) 하부에 밸러스트(120)를 형성함에 있어서, 상기 센터보드(110)의 하부에는 통공(111)이 천공되고, 밸러스트(120)는 센터보드(110)보다 높은 비중을 갖는 중량물로 이루어지되 상기 밸러스트(120)의 상부 중앙에는 길이방향으로 센터보드 삽입홈(121)을 형성하고, 상부 양측에는 센터보드 삽입홈(121)을 관통하는 볼트체결공(122)이 형성되도록 하며, 상기 센터보드 삽입홈(121)에 삽입된 센터보드(110)를 볼트(123)와 너트(124)에 의해 결합되도록 구성된다.In the present invention, in forming the ballast 120 in the lower portion of the center board 110 of the dinggi 100, the through hole 111 is drilled in the lower portion of the center board 110, the ballast 120 is a center board ( Consists of a weight having a higher specific gravity than 110, but forms a center board insertion groove 121 in the longitudinal direction in the upper center of the ballast 120, and bolt fastening holes penetrating the center board insertion groove 121 on both upper sides To form the 122, the center board 110 is inserted into the center board insertion groove 121 is configured to be coupled by the bolt 123 and the nut 124.

이때 상기 볼트(123)는 센터보드(110)에 천공된 통공(111)과 밸러스트(120)의 상부 양측에 천공된 볼트체결공(122)을 관통하여 너트(124)에 나사 결합된다.At this time, the bolt 123 is screwed to the nut 124 through the through holes 111 and the bolt fastening hole 122 drilled in the upper both sides of the ballast 120 to the center board 110.

상기 센터보드 삽입홈(121)은 센터보드(110)에 긴밀하게 삽입되도록 함이 견고한 결합을 위해 바람직하다.The center board insertion groove 121 is preferable to be firmly inserted into the center board 110 to be tightly coupled.

상기 밸러스트(120)는 딩기정(100)의 안정적인 선박의 운행을 가능하게 하며, 이를 위해 센터보드(110)보다 높은 비중을 가져야 한다. 따라서 비중이 매우 높은 금속재질로 제조됨이 바람직하다.
The ballast 120 enables the stable ship operation of the dinggi 100, and for this purpose it should have a higher specific gravity than the center board (110). Therefore, the specific gravity is preferably made of a metal material having a very high.

이처럼 상기한 구성을 갖는 본 발명이 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.
