본 발명은 범선용 돛을 접고 펴는 장치에 관한 것이다.The present invention relates to a device for folding and straightening sails for sailing vessels.

종래, 범선의 돛을 접고 펴는 장치에는 제1도 내지 제4도와 같은 구조의 것이 있는 바, 그 제1도는 돛을 편 상태의 정면도.Conventionally, the apparatus for folding and extending a sail of a sailing boat has a structure having the same structure as that of FIGS.

제2도는 그 평면도이고, 제3도는 돛을 접은 상태의 측면도, 제4도는 그 평면도이다.FIG. 2 is a plan view thereof, FIG. 3 is a side view of the sails folded, and FIG. 4 is a plan view thereof.

제1도 및 제2도에서 부호(1)는 강판이고, (2)는 고정대(2), (3)은 고정대(2)상에 설쳐되어 그 고정대(2)의 중심선과 일쳐되어 회동할 수 있게 한 돛대이다. 그 돛대(3)는 제2도에 도시한 바와 같이 양측에 유착부(5)(5')로 부착된 돛(4)(4')과의 면이 일쳐되는 앞면(3')이 있고, 돛(4), (4')은 자유계수(a), (a') 및 (b), (b')를 통하여 링크(6), (6') 로 로드(7)에 연결되어 있다. 로드(7)의 하방에는 유압실린더 기구(8)가 설치되고 그 유압실린더 기구(8)를 조작하여 로드(7)를 하방으로 이동함에 따라 링크(6), (6')의 측(7)이 하방으로 끌리어서 제3도 및 제4도에 도시한 바와 같이 돛편(4), (4)이 접어지게 된다. (9a), (9b), (9c)는 베어링이고 (10a), (10b), (10c)는 돛대(3)와 베어링과의 지지체(11)은 유압모우터, (12)는 피니온, (13)은 돛대(3)에 설치된 링기어이다.In FIG. 1 and FIG. 2, reference numeral 1 denotes a steel plate, reference numeral 2 denotes a fixture 2, and 3 denoted on the fixture 2 so as to be aligned with the centerline of the fixture 2 to rotate. It is a mast made. As shown in FIG. 2, the mast 3 has a front surface 3 'on which sides of the mast 3 are aligned with the sails 4 and 4' attached to the coalescing portions 5 and 5 '. The sails 4, 4 ′ are connected to the rod 7 via links 6, 6 ′ via free coefficients a, a 'and (b), b'. The hydraulic cylinder mechanism 8 is installed below the rod 7 and the hydraulic cylinder mechanism 8 is operated to move the rod 7 downward so that the side 7 of the links 6 and 6 'is moved. The sail pieces 4 and 4 are folded as shown in FIGS. 3 and 4 by being pulled downward. 9a, 9b, and 9c are bearings, 10a, 10b, and 10c are the support of the mast 3 and the bearing, 11 is a hydraulic motor, 12 is a pinion, 13 is a ring gear installed in the mast 3.

제4도에 도시한 바와 같이 돛을 접은 상태에서는 될 수 있는 한 저항을 적게받을 수 있도록 폭(A)으로 나타낸 부분에서만 바람을 받도록 제어하고 있으며 그 폭(A)이 적을수록 바람의 저항이 적고 돛을 접는 성능이 좋다.As shown in FIG. 4, when the sail is folded, the wind is controlled to receive the wind only in the portion indicated by the width (A) so that the resistance is as low as possible. The smaller the width (A), the less the wind resistance. The ability to fold sails is good.

그러나 상술한 바와 같은 종래의 기구에 의하면 폭(A)을 돛의 전체폭의 약 18% 이하로 할 수 없는 것을 알게 된다.However, according to the conventional mechanism as described above, it is found that the width A cannot be made about 18% or less of the total width of the sail.

그 이유는 다음과 같다. 즉 로드(7)에 전달된 유압실린더 기구(8)이 하방으로 끄는 힘과 돛(4), (4')을 유착부(5), (5')에서 회동시키는 힘이 점점 적게 된다. 이에 대하여 돛(4), (4')을 제3도의 화살표와 같이 수직방향으로 끌어내리려고 하는 힘은 점점 커져서 돛면의 강도상 나쁜 영향을 끼쳐게 된다. 즉 제4도와 같이 돛을 접은 상태에서, 로드(7)에 부설된 자유계수(b), (b')와 돛(4), (4')에 부설된 자유계수(a), (a') 사이의 수평거리(B)를 최대한으로 줄일 수 없으므로 폭(A)에도 한계가 생긴다.The reason for this is as follows. That is, the force which the hydraulic cylinder mechanism 8 transmitted to the rod 7 pulls downward, and the force which rotates the sails 4 and 4 'at the coalescing part 5 and 5' become smaller. On the other hand, the force that tries to pull the sails 4 and 4 'in the vertical direction as shown by the arrow in FIG. 3 becomes larger, which adversely affects the strength of the sail surface. That is, the free coefficients (b) and (b ') attached to the rod (7) and the free coefficients (a) and (a') attached to the sails (4) and (4 ') attached to the rod (7) while the sails are folded as shown in FIG. Since the horizontal distance (B) between) cannot be reduced to the maximum, there is a limit in the width (A).

상술한 바와 같이 돛을 접을 때의 돛의 성능 향상을 도모하기 위하여 폭(A)를 더욱 적게 줄일 수 있는 돛을 접고 펴는 방법이 요구되고 있다.As described above, in order to improve the performance of the sail when folding the sail, there is a demand for a method of folding and extending the sail, which can further reduce the width A.

본 발명은 상술한 종래 기술의 문제점을 해결하기 위하여 앙안된 것으로 일부가 돛면을 구성하고, 갑판상에 세운 돛대와, 그 돛대의 양측에 축설된 한쌍의 돛판과, 기 돛판의 후면에 수평으로 축설된 한 쌍의 돛판과, 그 돛판의 후면에 수평으로 설쳐된 복수의 유체실린더 기구와, 그 유체실린더 기구의 각 선단에는 일단이 유착되고 중간부가 대개 돛대의 후면에 수평으로 고정된 가설대에 수평으로 유착된 한쌍의 L자형 제1링크체와, 상기한 각 돛판에 일단이 유착되고 또 타단이 상기한 제1링크체의 타단에 유착된 한쌍은 제2링크체로 되며, 상기한 유체실린더 기구를 신축함에 따라 상기한 한쌍의 돛판을 돛대상에서 접고 펼 수 있게 하는 특징을 가진 것으로 본 발명의 실시예를 제5도 내지 제8도에 도시한 도단을 참조하면서 설명하건대 제1도 내지 제4도에 도시한 종래예와 같은 부분에는 같은 부호를 넣어서 설명한다.The present invention is to solve the above-mentioned problems of the prior art, a part of which constitutes a sail surface, a mast erected on the deck, a pair of masts built on both sides of the mast, and horizontally laid on the back of the base mast A pair of masts, a plurality of fluid cylinder mechanisms arranged horizontally on the rear side of the mast, and one end of each fluid cylinder mechanism at one end thereof, and a middle portion of which is usually horizontally fixed to the rear of the mast. A pair of L-shaped first link bodies adhered to each other and a pair of one end adhered to each of the sail plates and the other end adhered to the other end of the first link body are formed as a second link body, and the fluid cylinder mechanism is As described above, embodiments of the present invention will be described with reference to the dothans shown in FIGS. 5 to 8 as the pair of sail plates can be folded and unfolded from the sail target. The same reference numerals are given to the same parts as in the conventional example shown in FIG.

수평으로 회동되게 한 돛대(3)의 돛면 일부를 구성하는 앞면(3')의 양측부에 돛판(4), (4')이 유착부(5), (5')에 의하여 지지되고 (14a), (14b), (14c)는 돛대(3)의 후면에 수평으로 부착된 가설대인데, 그 가설대(14a), (14b), (14c) 내에는 유체 실린더 기구(15a), (15b), (15c)가 수평으로 설쳐되고 있다. 그 실린더 기구에는 각각 돛대(3)의 후부에 부착되고 그 로드의 선단은 가설대(14)에 중간부가 유착된 한쌍의 L자 형으로 형성된 제1링크체(16a), (16b), (16c)의 일단에 각각 유착되고 있다. (17a), (17b), (17c)는 일단이 돛판(4), (4')의 거의 중간부에 타단이 상기한 제1링크체(16)의 타단에 유착된 한쌍의 제2링크체이다.The mast plates 4 and 4 'are supported by the coalescing portions 5 and 5' at both sides of the front surface 3 'which form part of the mast surface of the mast 3 which is rotated horizontally (14a). ), (14b) and (14c) are temporary poles horizontally attached to the rear of the mast 3, and the cylinders 14a, 14b and 14c have fluid cylinder mechanisms 15a and 15b. ) And 15c are laid out horizontally. The cylinder mechanisms are respectively attached to the rear portion of the mast 3, and the ends of the rods are formed in a pair of L-shapes having a middle portion bonded to the temporary stand 14, the first link bodies 16a, 16b, and 16c. Are attached to one end of each. (17a), (17b), and (17c) are a pair of second link bodies, one end of which is bonded to the other end of the first link member 16, the other end of which is substantially in the middle of the sail plates 4 and 4 '. to be.

따라서 유체실린더 기구(15a), (15b), (15c)의 각 로드를 신장시키면 한쌍의 제1링크체(16a), (16b), (16c)는 그 돛체측의 선단이 돛대(3) 가까운 가설대(14a), (14b), (14c)와의 유착부를 축으로 하여 회동하고 이에 수반하여 한쌍의 제2링크체(17a), (17b), (17c)를 통하여 돛판(4), (4')은 유착부(5), (5')를 중심으로 돛대(3)상에서 제8도와 같이 접어진다. 한편, 상기한 유체실린더기구(15a), (15b), (15c)의 각 로도를 수축하면 돛판(4), (4')은 유착부(5), (5')를 축으로 하여 제6도와 같이 펴지게 된다.Therefore, when the rods of the fluid cylinder mechanisms 15a, 15b, and 15c are extended, the pair of first link bodies 16a, 16b, and 16c has the front end of the mast side close to the mast 3; Rotating around the abutment part with the hypothesis 14a, 14b, 14c, and accompanying it, the sail plate 4, 4 through a pair of 2nd link bodies 17a, 17b, and 17c. ') Is folded as shown in FIG. 8 on the mast 3 about the coalescing portions 5 and 5'. On the other hand, when the respective roadways of the fluid cylinder mechanisms 15a, 15b, and 15c are contracted, the sail plates 4 and 4 'have a sixth axis with the coalescing portions 5 and 5' as their axes. Spread out together.

그리고 제6도에 있어서 (18), (18)는 안내 레일인데 이것은 반듯이 필요한 것은 아니다.In Fig. 6, (18) and (18) are guide rails, which are not necessary.

이상에서 설명한 바와 같이 본 발명에 의하면 제1링크체, 제2링크체가 수평 운동하면서 돛체를 접고 펴는 작동을 하는 것이므로 돛면에 불필요한 힘이 작용하지 않고 돛을 접을 수 있고, 또 폭(A')(제8도 참조)은 돛을 폈을 때에 전체 폭의 15% 이하로 할 수 있으므로 돛을 접었을때, 풍향을 제어할 경우, 바람의 저항을 대폭으로 감소시킬 수 있는 유용한 효과를 가져다 주는 것이다.As described above, according to the present invention, since the first link body and the second link body operate to fold and straighten the sail while horizontally moving, the sail can be folded without unnecessary force on the sail surface, and the width A '( 8) can be 15% or less of the total width when sailing, so when the sail is folded, controlling the wind direction has a useful effect of greatly reducing the wind resistance.
